JOSE CARLOS DE SOUZA ABRAHAO, MD<br />

President, <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong><br />

Healthcare delivery to populations is constantly subject to change. With globalization,<br />

technological advances and new developments, large numbers of people can be<br />

reached quicker, with increasingly specialized and skilled levels in delivery of care.<br />

This scenario, which is being transformed by pursuit of healthier lifestyles, reduction in<br />

alcohol and tobacco consumption, and promotion of physical activity, is also a reflection of<br />

the strategies implemented in the field of preventive medicine.<br />

The <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong> (IHF), to echo these trends, has renamed the<br />

<strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong> Reference Book – <strong>Hospital</strong> and Healthcare Innovation<br />

Book. In this renamed publication, the articles featured, highlight advancement and<br />

developments in healthcare delivery and health services management. Through this<br />

medium of exchange in knowledge, ideas and practices, it is hoped that the innovations<br />

may serve to ensure a better future for the sector and that high quality standards are<br />

maintained in service delivery.<br />

From this edition, leaders and professionals will gain knowledge in activities in the<br />

treatment of breast cancer; the management of burn patients; trends and alternatives to<br />

reduce the risks of heart diseases; and strategies for surveillance and immunization against<br />

infectious and contagious diseases such as the Influenza A (H1N1).<br />

Within the scope of sustainability, it is worth drawing attention to the role “green actions”<br />

should play in planning of healthcare facilities. The advancement in technology can be an<br />

ally in controlling the effects caused by environmental changes. An example is the use of<br />

satellite imagery in the monitoring of climatic and environmental conditions around the<br />

world, in order to predict and prevent the emergence of infectious and contagious diseases.<br />

These and other issues are featured in this first edition of <strong>Hospital</strong> and Healthcare<br />

Innovation Book. We hope that this exchange of knowledge produces new strategies and<br />

creates opportunities for healthcare managers around the world. Beyond the differences<br />

between countries, all health services are facing and will face, over the coming years, the<br />

challenge of developing ways to ensure provision of better healthcare to their population.<br />

With this thought we hope to contribute in a dynamic and innovative way for the future of<br />

health.<br />

We wish you all a good read. ❏<br />

Introduction<br />

Introduction<br />

ERIC DE ROODENBEKE, PhD<br />

Chief Executive Officer, <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong><br />

Innovation does involve a revolution, but rather the appropriate<br />

use of inventions to enhance the result of a process.<br />

Opportunities for innovation are very frequent in health services<br />

and this is the reason why <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong> (IHF)<br />

has decided to rename its reference yearbook The <strong>Hospital</strong> and<br />

Healthcare Innovation Book. This move is not to look more<br />

fashionable or to present a cutting edge image, but it is simply to<br />

emphasis the potential of adopting new approaches to enhance<br />

hospital performance. As a vehicle for cross fertilization of<br />

knowledge, IHF must also show that decision makers should not<br />

only constantly think out of the box but should also rely on<br />

activities that have achieved successful results in a given<br />

environment.<br />

Innovation does not involve systematically experimenting but it<br />

is more often customizing and introducing, at full scale or within a<br />

new environment, that which has been proven effective or initiated<br />

locally at a small scale. Innovation also presents leaders of health<br />

services the opportunity to observe evolution in the various<br />

healthcare related activities both beyond and across borders. This<br />

annual publication offers a chance to gain an insight into matters<br />

that would not ordinarily feature as priority in your daily schedule.<br />

It is the role of IHF to highlight all dimensions that may affect<br />

strategic development of healthcare facilities both in the<br />

developed and developing world. Because healthcare facilities<br />

confront life and death issues, there is little room for unproven<br />

experiences. There should, however, be readiness and openness<br />

to either explore or implement novel processes that may result in<br />

improved performance.<br />

It is also the role of IHF to encourage and assist decisionmakers<br />

of the individual facility in making choices as well as<br />

influencing policy-makers whose choices wrongly influence<br />

performance in service delivery.<br />

In this edition, you will have the opportunity to read how<br />

creativity can be applied to management and should not only be<br />

considered as the territory of artists. It is obvious that by bringing<br />

creativity in the organization, top managers can both engage the<br />

staff and create an extraordinary movement and stimulation. In an<br />

ever rapidly evolving world, it is important to reconcile the need to<br />

rely on data and the capacity to look for new approaches that<br />

cannot be <strong>document</strong>ed.<br />

On the other hand, the reader will discover a new approach in<br />

risk and emergency confrontation. This concept is contrary to that<br />

of creativity, as it addresses the ways in which processes to<br />

reduce vulnerability and response to any potential disaster, can be<br />

reconciled in hospitals and healthcare facilities. This year, as past<br />

years, has witnessed catastrophes and with each event, the<br />

capacity of healthcare facilities to respond immediately to<br />

emergencies, has made a difference in survival and treatment of<br />

the injured. This very comprehensive article should be considered<br />

as a key tool for hospital decision-makers, with which to ensure<br />

they take seriously their role and responsibility in providing safety<br />

to the population they serve. If responding to the demand for care<br />

is an obvious function of hospitals it is not always the same for<br />

providing safety to the population. Recognition of this factor,<br />

before rather than after the occurrence of a disaster, is possible<br />

through advocating for and adoption of a comprehensive<br />

approach. Funding should not be an issue if politicians are<br />

convinced of such a role. Response to fire threats is an accepted<br />

priority around the world and fairly well resourced, healthcare<br />

decision-makers should, therefore, make a case for having a<br />

similar support when it comes to health threat.<br />

This year communicable diseases have been very much under<br />

the spotlight with the H1N1 flu threat. Although, to date, this threat<br />

has failed to manifest as a real public health issue when the death<br />

toll is compared with that from annual seasonal flu epidemics,<br />

hospitals and healthcare facilities have, nevertheless, been on the<br />

front line to respond. The IHF has surveyed major hospital and<br />

healthcare associations and found that they have all been involved<br />

in one form or another in the response strategies developed (<strong>Full</strong><br />

survey results: www.ihf-fih.org). Enhancement of influenza<br />

surveillance in order to avoid excessive and costly mobilization<br />

should be the way forward, in order to prevent the consequences<br />

of lack of preparedness. When reading the other articles related<br />

to infectious diseases you will appreciate and come to understand<br />

emerging issues, one of which addresses the issue of coverage by<br />

immunization. The work done on hepatitis B vaccine provides a<br />

warning with regards to the use of treatment in facilities, which may<br />

stimulate resistance and thereby result in a reduction in the<br />

coverage of immunization programmes. The change in<br />

environment has an impact in the development of communicable<br />

diseases. Satellite images can help to shape adequate responses<br />

ahead of time, not through major investment but just by appropriate<br />

use of existing technologies. While advanced technology should<br />

not be disregarded the appropriate use of low-technology has still<br />

to be better mastered. The existing event-based outbreak<br />

systems can provide large support in decision-making by<br />

<strong>Hospital</strong> and Health-care Innovation Book 2009/2010 09


Introduction<br />

monitoring the evolution of an outbreak.<br />

All countries are currently facing the double burden of diseases<br />

with the growing importance of non-communicable diseases<br />

(NCDs) in the emerging and developing world. For this reason<br />

there is need to attach much importance to matters relating to<br />

responses to injuries like burn management as well as to<br />

cardiovascular risks and cancer, for such population groups in a<br />

deprived area of a rich country like Australia. We also have an<br />

opportunity to reflect on the fact that although enhanced medical<br />

knowledge helps in improving outcomes, illness is also related to<br />

psychosocial conditions. Failure to fully appreciate this treatment<br />

source can undermine potential success.<br />

The article which argues that surgery should be considered as<br />

part of the primary care package of services, demonstrates how<br />

by reconsidering the place of intervention and the role of health<br />

professionals, it is possible to provide response without mobilizing<br />

massive resources. The Human resource shortage calls<br />

professions to reconsider their ability to respond to growing<br />

challenges. By featuring the article on physical therapy, IHF has<br />

sought also to expose the diversity of skills needed in caring for<br />

patients. In relation with the role of physical therapists the issue of<br />

patient handling shows the importance of using best practices to<br />

face this situation while protecting the health of workers.<br />

Last but not least, it was not possible to cover a large spectrum<br />

of issues without having an article related to patient safety.<br />

Appropriate use of recommendations can make a big difference in<br />

results. Innovation can be simple things but well and<br />

systematically implemented.<br />

Finally, as there is now greater recognition of the role of the<br />

private sector in supporting health, it was important to highlight the<br />

role companies can play for the health of their workers. It is usual<br />

that in remote places where companies have a large workforce<br />

that they create their own facilities which in return benefit the<br />

population. For HIV treatments, it is also obvious that employers<br />

should play an important role in providing access.<br />

Like in any approach that covers a large spectrum of issues, it<br />

can be argued that there is not enough or too much on a topic and<br />

that some important topics are missing. This 2009/2010 edition is<br />

not intended to be comprehensive, but as mentioned above, it is<br />

to provide insight to decision-makers and enable them to embrace<br />

and absorb the full spectrum of available knowledge.<br />

I do hope you will have a pleasant reading and that one or<br />

another article will be a sparkle triggering innovation in your<br />

facility. ❏<br />

Innovation and strategy: creativity<br />

Creativity and innovation in<br />

healthcare management<br />

ARTICLE BY BY KENNETH HEKMAN, MBA<br />

President, Health Development <strong>International</strong><br />

Creativity may be one of the most misunderstood topics in management. Creativity is usually associated with artists,<br />

those rare people who seem to be endowed with a mystical ability to make aesthetic sense out of colour, texture, shape<br />

and form. In the manager’s world, creativity is typically limited to picking out artworks for the walls of a new office or<br />

selecting a designer to develop a new logo.<br />

Some managers even find the topic of creativity to be<br />

threatening. In the logical world where decisions are based<br />

on statistical and financial data, working with abstractions<br />

rather than policies and procedures can be threatening. If artists<br />

do not use familiar methods, how can we measure their outcomes<br />

or judge their work? Likewise, how can creative geniuses<br />

appreciate managers’ logic and business acumen? We just don’t<br />

talk the same language.<br />

But artists, writers and inventors work with concepts that<br />

healthcare managers can benefit from learning. Their tools and<br />

language may be different, but their results can inspire, inform and<br />

enrich people in all walks of life.<br />

Why innovate?<br />

One area where artists and healthcare managers can agree is that<br />

the world is changing. Change is constant. Futurists tell us that<br />

knowledge is increasing at exponential rates and that we must get<br />

accustomed to the idea of change with increasing speed. In a<br />

single generation, we have seen the development of personal<br />

computers, faxes, email and the internet, with each creation<br />

bringing us closer to real-time transactions and communication<br />

options unimagined a few decades earlier. Change is the one<br />

constant in every aspect of our work and relationships.<br />

Change is often disruptive. It challenges routine ways of thinking<br />

and working. It makes us uncomfortable and requires us to adopt<br />

unfamiliar processes as we adapt to a new ways of thinking and<br />

working. Health care delivery seems to be at the apex of disruptive<br />

change. Laparoscopic surgical techniques are making some<br />

open-incision methods obsolete. New pharmaceutical options are<br />

reducing the length of hospital stays. A global recession is proving<br />

to challenge personal values and adjust priorities for funding<br />

agencies.<br />

Change can also stimulate creativity. Artists sometimes look for<br />

opportunities by studying contrasts and conflicts between light<br />

and dark, young and old, clean and dirty. Healthcare managers<br />

can also look for opportunities brought about by change. Eastern<br />

bloc countries are finding opportunities to improve healthcare<br />

delivery by adopting free market enterprise business models in<br />

contrast to the former state-run institutions. African hospitals are<br />

looking for ways to prevent malaria so they can reallocate limited<br />

inpatient resources for other diseases. Asian healthcare leaders<br />

are seeking ways to improve service attitudes of healthcare<br />

workers in an effort to stem the tide of conflicts from dissatisfied<br />

patients. Changes and conflicts stimulate adaptive ideas and<br />

behaviours. Healthcare managers who embrace changes and<br />

learn from conflicts are more able to anticipate the consequences<br />

and adapt more rapidly.<br />

Just as physicians on the cutting-edge of medical research find<br />

new diagnostic and treatment options for combatting disease, so<br />

also healthcare managers on the cutting-edge of innovative<br />

management techniques lead the way in discovering methods for<br />

improving clinical outcomes, gaining efficiencies and building<br />

healthier communities. Healthcare managers who are constantly<br />

searching for best practices worthy of adoption at their own<br />

hospitals and clinics gain a competitive advantage over others and<br />

advance the standards for quality of care and organizational<br />

performance. Innovators create new paradigms that make other<br />

methods obsolete. They introduce fresh ways of thinking and<br />

acting that advance civilization itself.<br />

What makes innovators different?<br />

Innovative healthcare managers can be found in every country and<br />

organizational setting. Innovation or creativity is not constrained by<br />

the presence of resources. In my experience as a healthcare<br />

consultant and trainer on five continents, some of the most<br />

innovative healthcare managers are those who become<br />

resourceful because of resource constraints. Adversity can<br />

stimulate invention rather than stifle it.<br />

Everett M Rogers, author of Diffusion of Innovations describes<br />

innovators as the earliest adopters of new technology and ideas. 1<br />

He describes them as venturesome, eager to try new ideas,<br />

sometimes desiring the hazardous, the rash, the daring and the<br />

risky. They comprise only about 2.5% of the population. Another<br />

13.5% are early adopters. They are more respectable opinion<br />

Innovation and strategy: creativity<br />

leaders and are viewed as role models by their peers.<br />

Some of the most innovative healthcare managers exhibit the<br />

following qualities:<br />

✚ They are consistently curious and eager to learn. Their<br />

commitment to continuous learning also requires them to<br />

abandon ideas that are no longer useful or that get in the way<br />

of advancing knowledge and understanding. They invest in<br />

themselves and their teams by expanding their management<br />

skills, exploring trends in healthcare and in other industries,<br />

visiting other organizations and reading a wide variety of<br />

management literature. They may take online courses and<br />

local workshops to learn from leading experts in healthcare<br />

management and to extend their network with other healthcare<br />

managers. They may engage a mentor to help them honestly<br />

assess their competence and to guide their career path.<br />

✚ They foster a freedom to experiment, even if it means there<br />

will be failures. Innovative healthcare managers understand<br />

that employees grow and thrive when they have opportunities<br />

to express their ideas and try new methods for improving<br />

patient care. They also understand the need to preserve and<br />

protect patient safety, and they strike a healthy balance<br />

between experimentation and tradition by regularly reviewing<br />

policies and procedures. The key is to create an environment<br />

where employees feel safe in suggesting new ideas that<br />

advance the standards for quality assurance.<br />

✚ Innovative managers dare to take a creative approach to<br />

ordinary decisions. Nobel Prize winner, Albert Szent-Györgyi,<br />

said, “Discovery consists of looking at the same thing as<br />

everyone else and seeing something different.” For the<br />

healthcare manager, that might mean looking at the pressure<br />

of competition and seeing a niche that others have overlooked.<br />

A creative administrator might view patient complaints as<br />

opportunities for service improvements or look at compliance<br />

challenges for their potential to improve clinical quality.<br />

Discovery can be a simple thing like playing with scheduling<br />

options to improve throughput or being open to fresh ideas<br />

from employees to reduce turnover. The creative healthcare<br />

manager looks beyond traditional problems to “see something<br />

different.” They conduct brainstorming sessions to draw out<br />

the best ideas of front-line staff. The technique, which was<br />

translated at a workshop in Latin America as “a thunderstorm<br />

of ideas,” empowers employees to take personal responsibility<br />

for solving problems. Front-line staff members encounter<br />

operational problems first and often see solutions before<br />

managers do.<br />

✚ Innovators commit to strategic planning for their organizations.<br />

They devote a few days each year to assemble department<br />

supervisors and the management team to evaluate how well<br />

the organization is serving its community. They analyze the<br />

trends impacting the hospital’s future, assess their readiness to<br />

meet new challenges and set goals for achieving<br />

improvements in operations and in service to the community.<br />

Every organization can benefit from planning. It takes<br />

courageous leadership to initiate the process and follow<br />

through with the plan, applying creative solutions to business<br />

development challenges.<br />

Examples<br />

Innovators can be found in the executive suites and on the front<br />

lines in healthcare delivery systems. Creative managers are<br />

sometimes recognized for their innovation by public awards, but<br />

unsung heroes can also be found in the daily experiences at<br />

hospitals, clinics and public health programmes in every culture.<br />

Here are a few examples:<br />

✚ Quint Studer became the administrator of a hospital in Florida<br />

USA based on his reputation for improving patient satisfaction<br />

at his previous employer. When he started, he approached<br />

employees, one at a time to introduce himself. He said, “Hi.<br />

My name is Quint Studer. I’m the new administrator here and I<br />

work for you. What can I do for you today?” A nurse asked<br />

him to trim the bushes near where she parked her car so it<br />

would be safer for her when she finished her shift after dark.<br />

While she worked, he had the bushes trimmed and put up a<br />

small fence. She was impressed that this administrator cared<br />

about her safety and shared the story with her co-workers. He<br />

earned their trust for other, more significant changes as time<br />

went on. 2<br />

✚ An engineer at a hospital in the Philippines looked for a way to<br />

assure a reliable flow of oxygen from the central supply area to<br />

the surgical suites. He developed a simple pipeline and<br />

adapted a water pump by reversing the polarity to convert it to<br />

a low-cost, highly reliable tool for delivering the vital resource<br />

to where it was needed most. While this method may not be<br />

fully compliant with requirements in all countries, it was efficient<br />

and effective in this setting.<br />

✚ At Park Nicollet, a medical clinic in Minnesota USA, inventory<br />

of medications was the third highest expense. Managing the<br />

inventory was crucial to the financial health of the organization<br />

as much as keeping current medications was vital to patient<br />

care. Managers found that at three departments in one<br />

location, approximately 628 individual containers of medication<br />

were stored with an overall price tag of US$ 32,513. Of this<br />

amount, 28% were high-cost, low-use medications - items<br />

regularly stocked but infrequently used. By setting up a system<br />

that automatically signaled when new items were needed,<br />

improvement teams eliminated 29% of the stock in one<br />

location and reduced cost by 50%. 3<br />

✚ At Selian Lutheran <strong>Hospital</strong> in Tanzania, managers were<br />

frustrated that only 50% of HIV-AID patients in nearby villages<br />

would comply with the requirement for regular visits to the<br />

clinic to receive the medications needed to keep them alive.<br />

They rallied the assistance of some of the more responsible<br />

patients to become mentors to their co-sufferers. The<br />

voluntary adherence counselors befriended others with HIV-<br />

AIDS and raised the compliance rate to 90%. 4<br />

Examples like these may sound like simple common sense, but<br />

common sense often fails to become common practice.<br />

Innovative healthcare managers search for ways to improve clinical<br />

outcomes, employee engagement, resource usage and the<br />

satisfaction of patients, visitors and staff at every opportunity. They<br />

recognize that simple tactics can sometimes yield exponential<br />

results.<br />

I think I can<br />

If ingenuity doesn’t come naturally, you are not alone; but the good<br />

news is that creativity appears to be a learned behavior. Creativity<br />

begins with a positive attitude, confidence and belief in your<br />

Innovation and strategy: creativity<br />

abilities. Roger von Oech, author of A Whack on the Side of the<br />

Head, 5 describes an extraordinary insight from the experience of a<br />

major oil company. The management team was concerned about<br />

why some of their research and development people seemed to<br />

have more productive and better ideas than others. They brought<br />

in psychologists to study educational backgrounds, where people<br />

grew up, favourite colours and other issues. After three months of<br />

study, the psychologists concluded that the chief factor that<br />

separated the two groups was that the creative people thought of<br />

themselves as creative, and the less creative people didn’t. Those<br />

who held a creative self-concept allowed themselves to get into an<br />

innovative frame of mind and to play with their knowledge. Those<br />

who didn’t embrace their creativity were either too practical or<br />

were caught in routines in their thinking.<br />

Healthcare managers can learn to be creative, and their<br />

innovation can lead to improvements in clinical quality, financial<br />

results and community impact. Approaching problems with an<br />

innovative frame of mind can yield surprising results and restore<br />

a fresh motivation for making a difference as a healthcare<br />

manager. ❏<br />

Innovation and strategy: risk management<br />

A comprehensive risk and emergency<br />

management programme for<br />

hospitals: a new approach<br />

ARTICLE BY MARCEL R DUBOULOZ<br />

Senior Medical Consultant, Health Development Counseling and Audit (HDCA) – Geneva<br />

This article looks at risk management in hospitals and the management of emergencies and disasters. It<br />

considers the models and policies that exist in private companies and the core components of a risk<br />

management strategy for hospitals. Building on this knowledge the author puts forward a new plan for<br />

hospitals called the Comprehensive Risk and Emergency Management Programme (CREMP) and explains the<br />

advantages of this approach.<br />

The World Health Organization (WHO) has, over the years,<br />

advocated adoption, by all Members States, laws and<br />

regulations for safer hospitals during major crisis and<br />

disasters. The United Nations <strong>International</strong> Strategy for Disaster<br />

Reduction (UNISDR) and WHO launched the 2008-2009<br />

campaign for “safe hospitals”, the primary focus of which is the<br />

reduction in “vulnerabilities” 1 , that result in major loss of life,<br />

services in hospitals. Global indicators show that lack or weak<br />

management of vulnerabilities in hospitals lead to catastrophic<br />

loss in services in both high and low-income countries. The 2009<br />

World Health Day was dedicated to “safe hospitals”. Besides<br />

providing care, hospitals also have a major role to play in<br />

management of public health programmes during disasters and<br />

health crisis. With hospitals acting as key sources of information in<br />

the surveillance system 2 , priority is now increasingly being given to<br />

development of the concepts of continuity of delivery of essential<br />

services and surge capacity. <strong>Hospital</strong>s are not isolated islands:<br />

therefore the objective should be to develop a global health<br />

system, prepared for disasters and major emergencies. There<br />

must be a continuum between the concept of “safer hospitals”<br />

(focus on reducing vulnerabilities) and mass casualty<br />

management. Management of hospital vulnerabilities is best<br />

addressed and controlled when brought into the broader concept<br />

of hospital risk management.<br />

Risk management in hospitals<br />

Many countries, over the years, have developed complex laws and<br />

regulations to regulate and control medical and other healthrelated<br />

activities 3 , such as medical practice, blood safety, quality<br />

assurance, safety and security, and accreditation. Ministries of<br />

Health (MoH) and/or specialized governmental institutions are<br />

often the bodies mandated to monitor compliance 4 . The majority<br />

of countries, however, have yet to develop exhaustive<br />

administrative and technical guidelines for full implementation of<br />

such policies as well as to identify and produce <strong>document</strong>ation on<br />

best practices.<br />

Management of emergencies and disasters<br />

Many countries have developed national multi-sectoral policies on<br />

management of emergencies 5 , particularly for mass casualty<br />

management (MCM) – also referred as Comprehensive<br />

Emergency Management Programme 6 (CEMP). The Ministry of<br />

Interior or a special Unit in the office of the Prime Minister is usually<br />

entrusted with the responsibility of developing and implementing<br />

the policies, from conception of plans to response management 7 .<br />

Some countries or States in USA have also adopted similar<br />

CEMPs for major governmental Institutions 8 . The trend is more<br />

and more to decentralize the response capacity 9 for MCMs. In<br />

these countries usually the MoHs have also developed their<br />

respective MCM policies, Emergency Medical Services (EMS)<br />

policies, and <strong>Hospital</strong> Emergency Response Plans 10 . The<br />

increasing trend is towards development of management of<br />

emergencies in hospitals within the framework of CEMPs 11 .<br />

Risk management in hospitals<br />

In parallel to development of the emergency (disaster)<br />

management strategies, many hospitals have introduced risk<br />

management approaches usually under the umbrella of<br />

Comprehensive 12 Risk Management Programmes 13 ”, the targets of<br />

which are regulated risks 14,15 , with the creation of specific<br />

committees for the different regulated risks. Many countries have<br />

national policies on risk management in hospitals, with technical<br />

guidelines for implementation 16 . The risks incorporated in these<br />

policies are primarily routine medical and clinical risks and the<br />

regulated risks. Disasters are not included in these programmes.<br />

<strong>Hospital</strong> accreditation is also a risk management-related<br />

regulatory tool applied in many countries. The prerequisite,<br />

however, for accreditation is the existence of a risk management<br />

programme as well as the existence of a hospital disaster plan.<br />

Often the process of accreditation is linked to the concept of<br />

quality assurance. Various methods (including checklists 17 ) are<br />

used to assess and monitor. Development of quality improvement<br />

strategies is gaining in importance with MoHs and hospitals. There<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 17


Innovation and strategy: risk management<br />

are many methods and software available for managing these<br />

different hospital programmes (risks management; quality<br />

assurance; safety). Increasing numbers of hospitals appoint a full<br />

time “Risk Manager” to contribute to the development,<br />

implementation and the management of such programmes. Also,<br />

many universities, professional associations and private schools<br />

offer training courses for “<strong>Hospital</strong> Risks Managers 18,19 ”. Although<br />

the exact structure of a given hospital risk management<br />

programme depends on the size of the facility and the scope of<br />

patient care and other services it offers, several key structural<br />

components are common and necessary for all hospital risk<br />

management programmes. Part of the business of “hospital risks<br />

management” is in connection with “vulnerabilities”. This is a<br />

complex issue as hospitals have various types of vulnerabilities<br />

that, when they interact with hazards or threats (the source of risk),<br />

can contribute to create risks. WHO has published several key<br />

<strong>document</strong>s on this particular issue 20,21 and launched a campaign in<br />

2008 22 as a direct contribution to improve awareness in this area<br />

and to advocate for the further development of existing hospital<br />

risk management programmes. The ISO 31000 (under<br />

preparation) on Risk Management will be a major step forward in<br />

promoting the adoption of risk management principles as a routine<br />

part of the management of hospitals.<br />

Models and policy in private companies<br />

Most of what is practiced in hospitals as risk management comes<br />

from the experiences gathered in the private sector over many<br />

years and much literature exists on these issues. “Business<br />

continuity”, “business safety”, “enterprise risk management”, and<br />

“comprehensive risk management” are concepts that have been<br />

applied by private companies for many years. Most of the private<br />

companies have adopted this strategic approach to ensure<br />

business sustainability and prosperity and to avoid preventable<br />

losses while others are specialized in offering services aimed at<br />

assisting the companies to “manage risks”. The notion of<br />

“business continuity” (continuity of operations for hospitals:<br />

continuity in the delivery of essential services) is given increasing<br />

priority in these programmes together with greater attention to IT.<br />

Business process management is the newly adopted strategy in<br />

this area by private companies for ensuring the success of<br />

business continuity and risk management.<br />

The diversity of models and conceptual frameworks in<br />

hospital risk management programmes and in hospital<br />

emergency (disaster) management<br />

The great diversity of concepts and programmes in risk<br />

management and emergency management allows countries to<br />

adopt models that best suit the local context. Nevertheless there<br />

are several major problematic issues in the two areas of hospital<br />

risk management and hospital emergency response plans (ERP;<br />

including contingency plans):<br />

✚ The Terminology. Unfortunately there is no international<br />

consensus on the key terms (e.g. emergency; risks 23 ;<br />

vulnerabilities; readiness; prevention; mitigation, recovery, safe<br />

hospital, essential services and so fort). It is therefore very<br />

difficult to compare existing risk management programmes<br />

18 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and strategy: risk management<br />

Figure 2: Comprehensive risk and emergency management programme Source: HDCA 2008<br />

(applicable to hospitals, private business or governmental<br />

institutions) or existing hospital ERPs. The various UN<br />

Agencies (ISDR; OCHA; WHO, etc.) have not yet agreed on a<br />

common terminology (adding to the existing confusion).<br />

✚ The great diversity of conceptual frameworks. There are<br />

several different conceptual frameworks dealing with the<br />

concepts of business continuity (continuity of operations for<br />

institutional agencies such as hospitals) and risk management;<br />

vulnerability analysis and reduction; hospital risks<br />

management. It is difficult to compare the various existing<br />

models due to the absence of clear indicators for assessing<br />

their usefulness, their effectiveness and their efficiency. The<br />

strategies adopted to pilot these programmes in hospitals also<br />

differ from one country to another or even from one hospital to<br />

the other in the same country. The indicators used to assess<br />

and monitor these programmes and the classification of types<br />

of risks also vary from one model to the other. In addition, the<br />

concept of ERP varies greatly from one country to other one:<br />

management systems; components 24 of the ERPs. The<br />

absence of universal references and best practices. There are<br />

no internationally agreed best practices, either for hospital risk<br />

management programmes or for hospital ERP. There are many<br />

different references in use and none of them claim to be of<br />

universal value.<br />

✚ The diversity of standards. Although there are international<br />

standards (ISO) for many activities, each country has<br />

developed its own standards for hospital risks management<br />

(regulated risks).<br />

✚ The great diversity of methodology, IT and software. In<br />

private businesses, risk management programmes have long<br />

been managed by using high technology and software. There<br />

are many computerized systems that are available for<br />

managing programmes and managing information 25 . They all<br />

have strengths and weaknesses. The data that are collected<br />

and processed vary greatly according to the IT used. There are<br />

several methods to assess the risks (especially to quantify the<br />

risks. Many different scales are in use to rank the risks). Many<br />

methods that are used in quality assurance process (which<br />

also includes a component on risk identification and<br />

management) are also used in RMP in hospitals.<br />

✚ The absence of a link between the hospital risk<br />

management programme and hospitals management<br />

during disasters and major crisis. Existing hospital risk<br />

management programmes focus mainly on the safety of<br />

patients and equipment and quality of medical care and<br />

services. There are very few programmes that also make<br />

mention of “risks arising from disasters”. There are no<br />

programmes that make clear and functional links between “risk<br />

management programmes” and “emergency management<br />

during major crisis and disasters”. In other words there are no<br />

programmes that clearly identify and specify the links between<br />

the <strong>Hospital</strong> Risk Management Programme and the ERP (of<br />

course the plan is made to facilitate the management of the<br />

response during emergencies). During disasters 26 hospitals<br />

have not only to focus on “continuity of operations” (especially<br />

for essential services) but they also must focus on the capacity<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 19


Innovation and strategy: risk management<br />

of the hospital to provide more such services (surge capacity)<br />

in order to contribute to the management of mass casualty<br />

situations. Medical surge capacity and medical surge capability<br />

is a key emerging concept for preparing hospitals to respond<br />

in disaster situations 27 .<br />

The core components 28 of risk management programmes 29<br />

in hospitals<br />

Although the exact structure of a given hospital risk management<br />

programme depends on the size of the facility and the scope of<br />

patient care and other services it offers, several key components<br />

are common and necessary to all hospital risk management<br />

programmes. It is, therefore, possible to identify some “core<br />

components” that are found in most existing programmes. The<br />

components selected in each model depend on the goal and<br />

objectives of the institutional programme. The hospital risk<br />

management programme, like other hospital “functions”, requires<br />

certain <strong>document</strong>ed policies and procedures to ensure programme<br />

consistency and uniformity. The plans, policies and procedures are<br />

usually approved and adopted in accordance with established<br />

hospital policy and in accordance with the existing laws and<br />

governmental monitoring mechanisms 30 . The most common<br />

objectives found in hospital risks management programmes are:<br />

✚ to identify and to prevent cause of injury or harm to patients,<br />

visitors, and employees and to treat the causes and or<br />

consequences should an adverse event happen;<br />

✚ to identify, to prevent or to manage events that can jeopardize<br />

the safety and security of the equipment and of the<br />

environment;<br />

✚ to manage as efficiently as possible the claims and lawsuits so<br />

that subsequent financial losses of the institution are minimized;<br />

✚ to contribute to quality improvement of services offered.<br />

In order to implement a risk management programme, as in any<br />

significant project in hospitals, the first step is usually to start with:<br />

✚ a census of existing regulations and laws applicable to the<br />

hospital (including safety and security) and to medical care and<br />

nursing services;<br />

✚ the establishment of the institutional long term vision, goal and<br />

objectives of the risk management programme;<br />

✚ the establishment of the planning committee and the<br />

identification and the description of the various components of<br />

the programme. This includes the strategic choice (when<br />

applicable) to decide how this risk management programme<br />

will include or not some other already existing “programmes”,<br />

such as quality assurance and accreditation; safety and<br />

security; clinical care safety; blood safety, drug safety;<br />

occupational medicine, etc. Usually all these existing<br />

programmes are integrated into this new “comprehensive 31 risk<br />

management programmes”. A major issue that the planning<br />

committee has to thoroughly discuss is the “management of<br />

information”. Indeed, hospital risk management programmes<br />

require the management of a huge quantity of data and an<br />

efficient system to computerize them. Clear indicators 32 must<br />

be identified and defined in order to monitor the programme<br />

and to revise the components of the programme when<br />

necessary;<br />

✚ identification of criteria for defining and classifying the events<br />

(critical event, etc.).<br />

The various components most frequently found in hospital risk<br />

management programmes are:<br />

✚ Organization and Programme Management System<br />

• Organogramme.<br />

• Roles and responsibilities of the various stakeholders. In<br />

almost all HRMP a “<strong>Hospital</strong> Risk Manager” (HRM) is<br />

appointed. This is a key position in the institution 33 .<br />

• Coordination mechanisms and management of information.<br />

Because of the wide range of risk management functions and<br />

the diversity of necessary activities, both formal and informal<br />

mechanisms for coordination and information exchange<br />

must exist between the risk management programme and<br />

other hospital departments and functions 34 . Coordination<br />

extends also to the outside world with local safety and rescue<br />

agencies (such as fire and ambulance services) and with<br />

governmental institutions having a normative role or a<br />

supervisory role (quality assurance; accreditation, etc.).<br />

• Methods and processes for “risk assessment”. There must<br />

be a system in place with the necessary tools and methods.<br />

The main steps are: 1) identification of risks; (2) analysis of<br />

risks identified; (3) treatment of risks; and (4) evaluation of<br />

risks treatment strategies: (5) ongoing monitoring (see figure<br />

135). There are many different methods for qualifying and<br />

quantifying risks 36 . Anyway an important step in identifying<br />

risk is to identify the “hazards” (or threats) that can engender<br />

risks when interacting with existing vulnerabilities 37 for that<br />

hazard. It is also vital to develop surveillance functions (early<br />

detection as much as possible; sentinel events, etc.) and<br />

monitoring functions in order to investigate all significant<br />

events, and to also assess the effectiveness of the treatment<br />

options and the evolution of the context and hazards. The<br />

notion of “readiness” is unfortunately sometimes mixed up<br />

with the notion of “resilience” in these programmes.<br />

Readiness is the major outcome of Emergency<br />

Preparedness Programmes. The use of modern technology<br />

contributes to safer management of the processes.<br />

• Funding of the programme and links with administration and<br />

finance department.<br />

• Training activities for key stakeholders of the programme and<br />

staff of the hospital.<br />

• Logistics and resources.<br />

✚ Description of “regulated risks” and safety of medical<br />

activities 38 that are often included into the HRMP:<br />

• blood safety;<br />

• drug safety;<br />

• nosocomial infection;<br />

• security measures and security equipment (especially for fire,<br />

gas, chemicals and nuclear products);<br />

• critical 39 equipment safety (including backup systems;<br />

redundancy, etc.);<br />

• clinical and medical safety (including activities performed by<br />

medical staff as well as the sustainability of the provision of<br />

these services by ensuring that the necessary environment40<br />

is adequate);<br />

• professional risks: those risks experienced especially by<br />

medical staff (doctors, nurses, etc.) performing clinical<br />

activities in relation with patient care.<br />

✚ Besides the above-mentioned “regulated risks”, there are<br />

20 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and strategy: risk management<br />

other “non-regulated” risks and emerging risks that occur more<br />

frequently, with sometimes great potential for severe<br />

consequences and substantial losses. Many HRMP do not<br />

include the “non-regulated” risks and are limited to only the<br />

“regulated risks” and the safety procedures that are necessary<br />

for quality assurance and accreditation. The trend,<br />

nevertheless, seems to be towards increasing consideration of<br />

non-regulated risks as part of the business.<br />

✚ Information management. This is a major component as<br />

HRMP requires management of l many data. Several key<br />

issues must be solved:<br />

• selection of the necessary and useful data (what, when, who;<br />

forms, use of computers; etc.);<br />

• quality of data (from collection to processing and use in the<br />

decision making process) and of the source of data;<br />

• confidentiality of data (data concerning patients; sensitive<br />

data concerning the hospital);<br />

• reporting mechanisms of any event that has a link with the<br />

Programme (especially critical events, sentinel and precursor<br />

events 41 ).<br />

Use of modern technology 42 . The use of modern technology for<br />

managing information facilitates the management of data<br />

pertaining to the HRMP and the data collected as routine activity.<br />

It enhances early detection of emerging risks (detection of signals),<br />

adverse events and precursor events (software intranet based or<br />

internet based).<br />

The emergency response plans of hospitals (disaster plans)<br />

In many countries the MoH has defined its policy on <strong>Hospital</strong><br />

Emergency Response Plans (from preparation of the ERP to the<br />

validation of the Plans). Contingency plans 43 (e.g. internal fire;<br />

bomb threat; Avian Influenza Pandemic, chemical incidents, etc.)<br />

are either included in the overall <strong>Hospital</strong> ERP as contingency<br />

procedures (SOP and Supplemental Emergency Response Plans<br />

of the various units and departments of the <strong>Hospital</strong>) or<br />

developed as contingency plans. Unfortunately in many<br />

countries the situation is chaotic: lack of national policy of the<br />

MoH (only few hospitals develop an ERP); lack of validation of<br />

the plans that are developed (no standardization; many plans are<br />

only paper <strong>document</strong>s that will never survive a real emergency).<br />

WHO has recommended a list of elements that must be included<br />

in the ERP of hospitals 44 . WHO has also developed toolkits for<br />

developing hospital ERP.<br />

Comprehensive Risk and Emergency Management<br />

Programme (CREMP) for <strong>Hospital</strong>s: the new approach 45 .<br />

The rationale for the integration of hospital risk management<br />

programmes (as a sub-programme) and hospital emergency<br />

management (as a sub-programme) into a cohesive overall<br />

Programme<br />

Many elements of the conceptual framework of Comprehensive<br />

Emergency Management used by communities (and<br />

governmental institutions at national or sub-national levels) can<br />

be applied to the management of hospitals during crisis and<br />

major emergencies. The preparation, the activation, and the use<br />

of the hospital ERP often mirror 46 the existing systems and<br />

mechanisms used in the wider community or at sectoral level,<br />

especially when focusing on special functions such as Incident<br />

Management Systems; EOC; Incident Command Group; logistic<br />

management; information management, etc. The adoption of a<br />

CREMP by hospitals must be based on the assessment of<br />

existing hazards (and threats) that could possibly affect the<br />

activities of the hospital or the assets (either impacting on them or<br />

requiring an important surge capacity in delivering essential 47<br />

service). In the context of Comprehensive Emergency<br />

Management in MCM, WHO advocates for capacity building at<br />

community level and for decentralization. The safe and efficient<br />

decentralization of the response capacity to sub-national levels<br />

and to community levels requires a clear national policy (and its<br />

application guidelines) and clear mechanism for transfer of<br />

authority, resources and financial means. <strong>Hospital</strong>s are a major<br />

assets to consider in MCM.<br />

The systems and the structures of the CREMP<br />

Clear rationale exists for integration of the Emergency<br />

Management System, as described in the ERP of the hospital,<br />

together with the various programmes dealing with risk<br />

management into an overall comprehensive programme. The<br />

general conceptual framework and the overall organization as<br />

well as the links between the components of these different subprogrammes<br />

are presented in the Figure 2. Emergency<br />

Management Australia (Governmental Agency) has already paved<br />

the way in this direction by combining together the subprogrammes<br />

of quality assurance and emergency risk<br />

management 48 . In this new conceptual framework, the notion of<br />

critical infrastructure is defined as follows: “A service, facility or a<br />

group of services or facilities, the loss of which will have severe<br />

adverse effects on the physical, social, economic or<br />

environmental well being or safety of the community”. It is<br />

particularly interesting to note that this notion also includes “a<br />

group of services or facilities”. Medical surge capacity largely<br />

depends on the effectiveness of the networks (as recommended<br />

by ADPC 49 ) that each hospital develops with the other<br />

stakeholders 50 .<br />

The main elements that of the various programmes (Quality<br />

Assurance; Emergency Management/ ERP; <strong>Hospital</strong> Risk<br />

Management Programme) are:<br />

✚ hazard and threat identification and assessment;<br />

✚ risk analysis (that requires also identification of vulnerabilities);<br />

✚ development and implementation of risk treatment options<br />

(which includes vulnerability reduction);<br />

✚ monitoring mechanisms;<br />

✚ coordination and management systems.<br />

The advantages of the CREMP<br />

The main advantages of adopting this integrated strategy in<br />

hospitals are:<br />

✚ Many management systems required for Emergency.<br />

Management/ERP and Risk Management Programmes/Quality<br />

Assurance are very similar. Indeed the management of severe<br />

events in Risk Management Programmes and the<br />

management of crisis during disasters require the mobilization<br />

of a “Command Group” and the development of an Incident<br />

Action Plan; the mobilization of resources (especially trained<br />

staff); the activation of special procedures and SOP; the<br />

management of information, etc. The pre-establishment of<br />

such structures and systems for responding to both situations<br />

will enhance efficiency and effectiveness, and will contribute to<br />

the rationalization of the cost (from equipment to training of<br />

key staff) and will facilitate the development of relevant and<br />

useful training activities<br />

✚ Many functions in both management systems are similar so<br />

that the use of common tools and methods (such as modern<br />

technology) will enhance the “reaction capacity” as early as<br />

possible (allowing for the selection of efficient treatment<br />

options as early as possible in order to prevent, to mitigate as<br />

many as possible adverse consequences).<br />

✚ Complementarities can be identified so that the acquisition of<br />

new resources can be rationalized and adequately selected, as<br />

well as training of staff.<br />

✚ The integration of the various “Committees” for regulated risks<br />

(e.g. Blood Safety Committee) into a cohesive whole, although<br />

the these technical Committees should still work in their field of<br />

competence.<br />

✚ The appointment of an <strong>Hospital</strong> Risk Manager in charge of<br />

contributing to the management of both Sub-Programmes is<br />

recommended.<br />

✚ The process for identifying vulnerabilities, hazards and risk is<br />

similar to all these programmes so that it is advisable to look<br />

for synergy and complementarities:<br />

• development of common procedures and tools;<br />

• data collection and reporting procedures;<br />

• data processing and information sharing;<br />

• training of stakeholders;<br />

• information management systems for hospital internal use<br />

and for coordination and reporting to higher levels.<br />

✚ Collection of many data as routine procedures are needed in<br />

all the sub-programmes to ensure surveillance, early warning,<br />

and the monitoring of both the efficiency of the programmes<br />

and of the management of risks.<br />

✚ The management of information 51 and the integration of all<br />

elements are now possible by using common integrated<br />

technology.<br />

✚ The pooling and sharing of information will contribute to<br />

improve the early identification of potentially severe adverse<br />

events or of infrequent events (such as cluster of unusual<br />

diseases or a new threat).<br />

✚ In many activities of these sub-programmes, the staff is the<br />

same, therefore enabling rationalization of training, awareness<br />

raising and development of a sense of ownership and<br />

stewardship.<br />

✚ Many treatment options are partly similar in these subprogrammes<br />

so that it is possible to use existing resources<br />

more efficiently (avoiding unnecessary duplication) or to acquire<br />

new resources in a coordinated manner.<br />

✚ Development of common terminology and of “institutional<br />

culture of risk and emergency management”.<br />

✚ Promotion of common national standards among all hospitals.<br />

✚ Promotion of cross-fertilized cooperation and coordination<br />

(avoiding vertical approach) within the hospital.<br />

✚ Enhancement of integration strategy of activities from all<br />

departments and units of the hospital.<br />

✚ Contribution to quality improvement.<br />

✚ Rationalization of the use of resources and of acquisition of<br />

new resources.<br />

✚ Contribution to a better understanding by the MoH of the<br />

actual problems and the priorities in the country, and<br />

identification of priority areas for further development (from<br />

policy making to monitoring and normative activities).<br />

✚ Contribution to an increased readiness of the health sector to<br />

respond to major emergencies and to detect new threats.<br />

✚ Contribution to better management of public health by the<br />

MoH. The creation of a national “risk observatory” fed by all<br />

hospitals in the country is recommended so that the MoH has<br />

a comprehensive view of the real context and of the priorities.<br />

This will also contribute to revision of national policies when<br />

necessary and to the development of national programmes<br />

when required. The development of this integrated CREMP in<br />

each hospital must also aim at contributing to a more efficient<br />

management of public health by the MoH and the provincial<br />

health departments.<br />

✚ Contribution to a more efficient management of resources<br />

such as selection by the MoH of equipment (safety; efficiency;<br />

costs, etc.) for hospitals.<br />

✚ Contribution to the development of efficient cooperation<br />

between hospitals (creation of networks of hospitals) in<br />

prevention as well as in response and crisis management.<br />

✚ CREMP will also contribute to identify the actual strengths and<br />

weaknesses of each hospital member of the network as<br />

services providers during crisis (either for receiving patients or<br />

as back up for logistics).<br />

✚ The identification of best practices applicable either to one of<br />

the Sub-Programmes or to both.<br />

✚ Cross-sectional sharing of lessons learned.<br />

Conclusion: Major issues that need further discussion at country<br />

level for developing this new approach<br />

Pre-requisite for launching CREMP project in an hospital<br />

First of all it should be clear that without a national policy (prepared<br />

by the MoH) on “regulated risks and quality assurance” on the one<br />

hand and an ERP on the other, hospitals would be undertaking<br />

major risks in considering implementation of an CREMP.<br />

Awareness-raising among all categories of staff is absolutely<br />

necessary in order to promote a strong sense of ownership by the<br />

hospital and of the stewardship by the MoH. It would, therefore,<br />

be advisable that there be agreement at administrative and care<br />

delivery decision-making levels on the necessity and on the<br />

rationale for developing the two Sub-Programmes and for their<br />

integration.<br />

In the case of hospitals with existing CRM and ERP Sub-<br />

Programmes (even though these may be if limited to a few<br />

regulated risks), launching of such a new approach for a new<br />

Integrated CREMP, is facilitated. It is still necessary, however, to<br />

engage strong commitment from key staff of both Sub-<br />

Programmes.<br />

Planning committee (roles, responsibilities; composition,<br />

activities) for integration of the two Sub-Programmes<br />

As in any major hospital project, it is vital to set up a planning<br />

committee. Indeed a CREMP will involve many stakeholders inside<br />

and outside of the hospital. As there is no “international model” for<br />

such a CREMP, each hospital will have to identify what are the<br />

exact planning activities that will be conducted either during the<br />

development of the two Sub-Programmes or for ensuring the<br />

22 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and strategy: risk management<br />

efficient integration of the two Sub-Programmes when they<br />

already exist. This Committee will have to decide on key issues<br />

such as: management structure of the CREMP and of the two<br />

Sub-Programmes; the level of integration of the two Sub-<br />

Programmes; common information management systems;<br />

methods and tools to be used for assessing risks (even if there<br />

are already methods and tools in use; integration would call for a<br />

new approach), etc. It is important that all key stakeholders of the<br />

two Sub-Programmes are represented in the Committee, either<br />

as permanent members or as temporary advisers when<br />

necessary. Cross-fertilised participation by managerial and clinical<br />

staff is necessary.<br />

Management structure and systems<br />

Many hospitals already have a RMP and an ERP. These<br />

Programmes, where they exist, have their own management<br />

structure although some key functions (such as the director of the<br />

hospital: chief of security, etc.) are members of both structures.<br />

The challenge here is to integrate as much as possible the<br />

“management structure for all risks” (including the risk arising from<br />

disasters) into one single “command structure”. Both Programmes<br />

require the technical expertise of different stakeholders in parallel<br />

to the presence of a common “core management group”.<br />

Therefore it is necessary to consider running two Sub-<br />

Programmes as complementary and in synergy and to integrate<br />

them into one single command structure of the CREMP.<br />

Depending on the size of the hospital and the services it provides,<br />

the complexity of the two Sub-Programmes will vary and therefore<br />

the composition of the management board of each of them.<br />

<strong>Hospital</strong>s should consider the appointment of a “<strong>Hospital</strong> Risk<br />

Manager” (highly qualified; adequately trained; having a high<br />

position in the hierarchy; appropriate authority).<br />

Methodology for assessing vulnerabilities<br />

There are many different methods for assessing the vulnerabilities<br />

of communities, hospitals and systems, areas in which private<br />

companies, for many years, have been very active. It is necessary<br />

that hospitals desiring to develop a CREMP, select the methods<br />

that best suit their facilities’ needs. Selection must be done also in<br />

coordination with the local community, other hospitals that are<br />

members of the local network, and in accordance with the policy<br />

of the MoH (when available). The use of simple techniques<br />

(qualitative) for the first estimate, is recommended for small-sized<br />

hospitals. Very sophisticated computerized quantitative<br />

techniques do not add much in terms of programme development<br />

and in effectiveness of the whole process of risk management.<br />

However, computerization of data is of paramount importance<br />

(see information management). WHO has published a system for<br />

assessing hospital vulnerabilities 52 . Nevertheless, it is<br />

recommended that external vulnerabilities (present in the<br />

surrounding community or in the system in which the hospital is a<br />

member) that can impact on hospital activities, be included. When<br />

selecting a method, the Planning Committee must consider the<br />

resources that will be necessary as well as the competencies of<br />

staff involved.<br />

Methodology for identifying the hazards and threats<br />

Selection of the methods that can be used must be done<br />

according to validated pre-established criteria.<br />

Methodology for assessing risks and ranking risks<br />

It is vital that all hospitals in one country use the same<br />

methodology. Training activities must be considered for those in<br />

charge of contributing to either identification or treatment of risks.<br />

Roles, functions, responsibilities and composition of the<br />

Incident Command Group –ICG– (the “brain” of the two Sub-<br />

Programmes); activation; resources; location of the<br />

Command Room<br />

These issues are usually discussed during the development of the<br />

ERP. But is is necessary to identify the specific components and<br />

the systems pertaining to a CREMP.<br />

Administrative support<br />

The support from and direct involvement of Administration<br />

(including HR, Finance, etc.) is necessary as in any major project<br />

in hospitals. The clear identification of the roles of the various<br />

stakeholders is necessary (especially in Administration).<br />

Logistic support<br />

The two Sub-Programmes require resources (from back-up<br />

systems and equipment to sophisticated technology). The<br />

rationalization of the acquisition, mobilization, monitoring of<br />

resources must be a continuous effort, including necessary<br />

training of staff.<br />

Information management<br />

The management of information in both Sub-Programmes is a<br />

complex issue as it involves different systems. For integration of<br />

these systems the following issues need to be discussed:<br />

i. data: selection, processing, reporting;<br />

ii. software and IT;<br />

iii. ongoing surveillance activities and special surveillance<br />

during health crisis (e.g. syndromic based, active reporting);<br />

iv. links with the national “observatory for hospital risks”;<br />

v. links with national policy making;<br />

vi. links with quality assurance and accreditation.<br />

Management of information also includes sharing of information<br />

with the MoH (health system and its management). This includes<br />

the mechanisms for sharing the information and development of<br />

new structures 53 at national level, to enable management of the<br />

information gathered by hospitals. Development of a CREMP will<br />

involve many stakeholders from different programmes (quality<br />

assurance; blood safety, etc..) and therefore require integration of<br />

all efforts and existing systems into a cohesive whole. This does<br />

not mean that the various existing programmes are no longer<br />

necessary. They need to be complementary and coordinated. The<br />

development of a more comprehensive and more coordinated<br />

policy on all these issues will contribute to the development of<br />

CREMP by hospitals.<br />

Monitoring process<br />

Monitoring will consist of a complex set of activities in this new<br />

concept of CREMP. The main elements that would need<br />

addressing are:<br />

✚ assessment of implemented risk treatment options (in both<br />

Sub-Programmes)<br />

✚ assessment of the Programme, involving<br />

1. reorientation and revision<br />

2. new technologies<br />

3. evolution of context, risks, and vulnerabilities<br />

Training activities and exercises<br />

As in any activity, staff is the key resource. Training of staff is of<br />

paramount importance. Exercises (from exercising the ERP to<br />

security, etc.) are vital. Training and exercises must be developed<br />

in a systemic approach. Much guidance from the MoH is needed<br />

in this area. This is a weak element in hospital preparedness at the<br />

moment almost everywhere around the world.<br />

Implementation of risk management processes<br />

Finally, in management of risks by private companies, there is<br />

increasing use of the conceptual framework of “Business<br />

Management Processes”. <strong>Hospital</strong>s seeking to develop a CREMP<br />

can certainly benefit in the use of this approach. ❏<br />

Problem: A multinational company with operations in several African countries was committed to offer antiretroviral treatment<br />

to its employees and their dependants. Approach The Accelerating Access Initiative (AAI), an initiative of six pharmaceutical<br />

companies and five United Nations’ agencies, offered the possibility of obtaining brand antiretroviral drugs (ARVs) at 10% of<br />

the commercial price. PharmAccess, a foundation aimed at removing barriers to AIDS treatment in Africa, helped to establish<br />

an HIV policy and treatment guidelines, and a workplace programme was rolled out from September 2001.<br />

Local setting: Private sector employers in Africa are keen to take more responsibility in HIV prevention and AIDS care. An<br />

important hurdle for African employers remains the price and availability of ARVs.<br />

Relevant changes: The programme encountered various hurdles, among them the need for multiple contracts with multiple<br />

companies, complex importation procedures, taxes levied on ARVs, lack of support from pharmaceutical companies in<br />

importation and transportation, slow delivery of the drugs, lack of institutional memory in pharmaceutical companies and<br />

government policies excluding the company from access to ARVs under the AAI.<br />

Lessons learned: The launch of the AAI enabled this multinational company to offer access to ARVs to its employees and<br />

dependants. The private sector should have access to these discounted drugs under the AAI. A network of local AAI offices<br />

should be created to assist in logistics of drugs ordering, purchase and clearance. No taxes should be levied on ARVs.<br />

HIV is the largest threat to adult survival in sub-Saharan<br />

Africa. According to UNAIDS, 33 million people were living<br />

with HIV by December 2007, of whom 22 million were in<br />

sub-Saharan Africa. In 2007 an estimated 1.5 million sub- Saharan<br />

Africans died of AIDS and an estimated 1.9 million became<br />

infected with HIV. 1 Several international initiatives were launched to<br />

increase funding for antiretroviral therapy. This has led to a<br />

spectacular increase in access to antiretroviral drugs (ARVs) in<br />

Africa: by April 2007 an estimated 28% of eligible HIV patients in<br />

sub-Saharan Africa were on ARVs. 2 One initiative that aimed to<br />

increase access was the Accelerating Access Initiative (AAI). This<br />

paper reports practical experiences of a multinational company<br />

with the AAI.<br />

Approach<br />

In May 2000 five United Nations organizations – United Nations<br />

Population Fund (UNFPA), United Nations Children’s Fund<br />

(UNICEF), WHO, The World Bank and the Joint United Nations<br />

Programme on HIV/AIDS (UNAIDS) – announced a partnership<br />

with five pharmaceutical companies to address the lack of<br />

affordable HIV medicines in resourcepoor settings. 3 This<br />

partnership, the AAI, 4 was committed to offer ARVs at about 10%<br />

of the commercial price to the public sector and nongovernmental<br />

organizations that complied with three conditions (correct use, no<br />

mark-up, no backflow of drugs to markets in developed<br />

countries). By September 2006, an estimated 424 000 Africans<br />

were treated with ARVs provided through AAI arrangements, 5<br />

most of them in public sector treatment programmes.<br />

In July 2001, multinational brewing company Heineken<br />

<strong>International</strong>, with headquarters in the Netherlands and operating<br />

companies (OPCOs) in several African countries, decided to<br />

include ART among the medical benefits for employees and their<br />

dependants, including children. The company, itself selling a<br />

brand beer, preferred to purchase brand ARVs, and accepted that<br />

this would make the programme more expensive. The AAI price<br />

reductions made the provision of ARVs to employees and<br />

dependants affordable for the company. A partnership was<br />

established with PharmAccess, a foundation specialized in<br />

a Some people might have been tested more than once. Due to turnover of the workforce, it cannot be calculated which proportion of the current workforce has been tested<br />

removing barriers to AIDS treatment in Africa.<br />

PharmAccess conducted assessments, provided training,<br />

helped define treatment protocols, provided laboratory support,<br />

established a web-based database for patient follow-up6 and<br />

conducted monitoring, evaluation and quality control.<br />

PharmAccess interacted with AAI to guarantee a continuous<br />

availability of ARVs at the OPCOs. The programme was gradually<br />

rolled out at 14 OPCOs in 6 countries: Burundi, the Congo, the<br />

Democratic Republic of the Congo, Nigeria, Rwanda and Sierra<br />

Leone. The average size of the workforce per OPCO varied<br />

between 200 and 500 employees; including spouses and children,<br />

the total target population was ± 30 000 of which 10 332 were<br />

adults (Table 1). Through the company’s voluntary counselling and<br />

testing programme, 531 infections were diagnosed among<br />

employees and dependants, and 273 HIV patients had started<br />

highly active ARV therapy (HAART) by mid- 2008.<br />

PharmAccess arranged purchase and shipment of ARVs and<br />

the OPCOs organized customs clearance and storage. The<br />

chosen first and second line regimens implied procurement of<br />

eight drugs from six different pharmaceutical companies.<br />

PharmAccess signed agreements with these six companies.<br />

Because neither the pharmaceutical companies nor PharmAccess<br />

had local offices in most of the six countries, the local OPCO had<br />

to clear the goods at customs. If the products were not yet<br />

registered in the country, the OPCO had to arrange temporary<br />

import permits. In the rare cases that a pharmaceutical company<br />

had a local office, this did not assist in ordering and receiving<br />

drugs for the company. It was difficult to import newer ARVs as<br />

they were usually not registered.<br />

Challenges<br />

After some time it became possible in some countries to purchase<br />

ARVs (both generic and brand) locally. If the drugs were<br />

prequalified by WHO, the OPCOs obtained ARVs locally through<br />

government agencies. The Ministry of Health in one country felt<br />

that drugs purchased with a grant from the Global Fund to fight<br />

AIDS, Tuberculosis and Malaria should not be re-sold, so it<br />

stopped the provision of drugs to the OPCO. The same<br />

government declined to provide free ARVs to the OPCO, arguing<br />

that a for-profit private company should not have access to free<br />

drugs. Given these challenges, the company sometimes<br />

purchased generic ARVs. Generic drug companies were generally<br />

more helpful than brand pharmaceutical companies in the<br />

importation of products through their local representatives. For<br />

newer drugs, the AAI was the only source of supply.<br />

Procuring ARVs was complex. Several pharmaceutical<br />

companies had not yet developed AAI-agreement <strong>document</strong>s and<br />

practicalities differed from one to another. Sometimes a<br />

pharmaceutical company insisted that PharmAccess should sign<br />

one agreement per country rather than one general agreement<br />

covering all sub-Saharan countries. The high turnover of staff in<br />

the pharmaceutical companies affected institutional memory; at<br />

times PharmAccess had to explain AAI procedures to new staff at<br />

pharmaceutical companies.<br />

The price discount that was obtained was different per product<br />

and per company and varied between 77% and 93%. The doorto-door<br />

delivery time of small ARV orders varied between 1 and 5<br />

months. Despite the explicit assurance that pharmaceutical<br />

companies would carry transport costs of ARVs, this was not<br />

always the case in practice. Surprisingly none of the<br />

pharmaceutical companies ever requested PharmAccess to<br />

provide evidence of drug flows or absence of mark-up.<br />

Lessons learned<br />

The AAI was set up as a public sector, country-led process. 7 This<br />

implied that the private sector in most African countries could not<br />

benefit from the AAI. We argue that allowing the African private<br />

sector employers, private clinics and private health insurance<br />

companies to obtain ARVs through AAI will contribute to more<br />

sustainable access for all patients in sub-Saharan Africa. 8<br />

Private sector employers in Africa are keen to take more<br />

responsibility in HIV prevention and AIDS care. 9 An important<br />

hurdle for African employers remains the price of ARVs; allowing<br />

them access to ARVs under the AAI would make a big difference.<br />

The overstretched African public health care sector would<br />

indirectly benefit from this, allowing increased access for the poor.<br />

The second sector that would benefit from AAI support is the<br />

private health care sector. Private clinics in Africa provide care to a<br />

substantial and increasing part of the population. 10 National<br />

governments should allow these clinics to use ARVs obtained<br />

26 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and stategy: Accelerating Access Initiative<br />

Box 1: Lessons learned<br />

• The private sector should have access to discounted ARVs<br />

under the AAI.<br />

• A network of local AAI offices should be created to assist in<br />

logistics of drugs ordering, purchase and clearance.<br />

• No taxes should be levied on ARVs.<br />

AAI, Accelerated Access Initiative; ARV, antiretroviral drugs.<br />

through AAI. The quality of the performance of these clinics should<br />

be assessed and monitoring is needed regarding markups on<br />

drugs; all private clinics providing ARVs should comply with<br />

national treatment standards. 11<br />

The third entity requiring access to AAI is the private health<br />

insurance sector in Africa. Private health insurance Africa but this<br />

situation is changing in several countries. 12 Health insurance and<br />

managed care may be instrumental in making African health care<br />

more self-supporting and less dependent on external donors.<br />

Therefore, African health maintenance organizations and health<br />

insurance companies should be given access to AAI-discounted<br />

ARVs. The launch of the AAI in the year 2000 enabled this<br />

multinational to provide ARV therapy to its employees, their<br />

spouses and children in Africa. The company’s experience with the<br />

AAI indicates the need for local AAI offices in African countries.<br />

Such offices could facilitate ordering, clearance and channel bulkprocurement<br />

of ARVs for the three private sector actors named<br />

previously.<br />

Registration of drugs is often problematic, importation is highly<br />

complex and taxes are being levied on ARVs. These issues should<br />

be addressed by African governments. The lessons learned are<br />

Recommendations<br />

The AAI has led to substantial price reductions of brand drugs and<br />

increased access to ARVs. Administrative, logistical and regulatory<br />

hurdles have meant that the full potential of the AAI has not been<br />

fulfilled. The following four recommendations are made to<br />

strengthen the AAI and increase access to affordable good quality<br />

drugs in sub-Saharan Africa. (i) AAI eligibility should be extended<br />

beyond the public sector. Local private clinics, health insurers and<br />

health maintenance organizations should get access to AAI ARVs,<br />

under specific conditions. (ii) Governments should waive taxes on<br />

ARVs, simplify and harmonize the drug registration process and<br />

certify private clinicians. (iii) Private companies and non-profit<br />

organizations that wish to provide ART to their employees and<br />

dependants should be encouraged to do so and should benefit<br />

from AAI. (iv) The pharmaceutical companies within AAI should<br />

support the creation of a network of local AAI distributors of ARVs.<br />

<strong>International</strong> donor funds should invest in this network. ❏<br />

The emergence of a novel strain of influenza virus A (H1N1) in April 2009 focused attention on influenza surveillance<br />

capabilities worldwide. In consultations before the 2009 outbreak of influenza subtype H1N1, the World Health Organization<br />

had concluded that the world was unprepared to respond to an influenza pandemic, due in part to inadequate global<br />

surveillance and response capacity. We describe a sentinel surveillance system that could enhance the quality of influenza<br />

epidemiologic and laboratory data and strengthen a country’s capacity for seasonal, novel, and pandemic influenza detection<br />

and prevention. Such a system would 1) provide data for a better understanding of the epidemiology and extent of seasonal<br />

influenza, 2) provide a platform for the study of other acute febrile respiratory illnesses, 3) provide virus isolates for the<br />

development of vaccines, 4) inform local pandemic planning and vaccine policy, 5) monitor influenza epidemics and<br />

pandemics, and 6) provide infrastructure for an early warning system for outbreaks of new virus subtypes.<br />

The emergence of a novel strain of influenza virus A (H1N1) in<br />

April 2009 and its subsequent rapid global spread have<br />

focused attention on influenza surveillance capabilities<br />

worldwide 1 . A consultation convened by the World Health<br />

Organization (WHO) in 2005 had previously concluded that the<br />

world was unprepared to respond to an influenza pandemic, due<br />

in part to inadequate global surveillance and response capacity 2 .<br />

The <strong>International</strong> Health Regulations 2005 call for strengthened<br />

surveillance for all events that may constitute a “public health<br />

emergency of international concern”; such events include<br />

individual human cases of influenza caused by a new subtype of<br />

influenza virus A 3 . As part of the <strong>International</strong> Health Regulations<br />

2005 core surveillance and response capacity requirements, each<br />

Member State must develop and maintain capabilities to detect,<br />

assess, and report disease events nationally and internationally to<br />

WHO within 48 hours of confirmation. However, reviews of<br />

national pandemic planning indicate that surveillance systems are<br />

often inadequate to support current preparedness strategies 4–8 .<br />

WHO has existing surveillance guidelines to help Member States<br />

implement universal surveillance for novel and pandemic<br />

influenza 9 , but the guidelines lack the specificity that would enable<br />

many countries to establish operational surveillance plans. Quality<br />

influenza surveillance systems are needed to enable countries to<br />

better understand influenza epidemiology, including disease<br />

incidence and severity, and help them implement appropriate<br />

prevention strategies. The challenges experienced by the United<br />

States and Mexico to rapidly determine the extent and severity of<br />

illness of the 2009 novel influenza A (H1N1) outbreak highlighted<br />

the need for systems that can reliably produce these estimates.<br />

Furthermore, global strategies to address other vaccinepreventable<br />

diseases have acknowledged the importance of<br />

establishing local disease burden (effects, severity, amount of<br />

illness, and costs) as a first step toward decisions about the<br />

introduction of vaccines into new countries. We describe a generic<br />

guideline for collecting data on severe acute respiratory infection<br />

(SARI), influenza-like illness (ILI), and laboratory-confirmed<br />

influenza that can be implemented in limited-resource settings.<br />

Current situation<br />

Global Influenza surveillance<br />

For 60 years, the WHO Global Influenza Surveillance Network<br />

(GISN) has provided virologic information used in the biannual<br />

process of selecting strains for the Northern and Southern<br />

Hemisphere influenza vaccine formulations. However, its capacity<br />

to provide epidemiologic data or an alert of an emerging pandemic<br />

is limited. GISN currently comprises 122 National Influenza<br />

Centers in 87 countries and 4 WHO Collaborating Centres for<br />

Reference and Research on Influenza 10 . Although this system has<br />

proven to be valuable, tropical and resource-limited countries<br />

(particularly in Africa) are underrepresented 11 .<br />

Innovation and policy: disease surveillance<br />

differences in cultural practices, the environment, geography,<br />

human genetics, and social structures. Enhanced influenza<br />

surveillance can permit assessment of a number of factors that<br />

may affect disease activity: population density, differences in<br />

prevalence and spectrum of chronic illness, proximity of the young<br />

and elderly, low proportion of elderly in the population, low school<br />

attendance, and school schedules that may not correspond with<br />

peak transmissibility season. The effectiveness of control measures<br />

such as social distancing and vaccination may differ between<br />

developed and developing settings because of these factors.<br />

Available epidemiologic evidence suggests that influenza is<br />

common in tropical regions and contributes substantially to<br />

disability and use of healthcare resources 12–16 . Data describing the<br />

seasonality and epidemiology of influenza in tropical areas are<br />

limited; however, some tropical countries report year-round human<br />

influenza activity 12 , unlike in temperate regions where transmission<br />

occurs with marked seasonality. Because of these limited data,<br />

most of the understanding of seasonal influenza is derived from<br />

epidemiologic data collected in western Europe and North<br />

America. Nevertheless, estimates of a pandemic impact indicate<br />

that most deaths will be in developing countries and that more<br />

than half will occur in southern Asia and sub-Saharan Africa 17 . A<br />

better understanding of the epidemiology of influenza in these<br />

areas would facilitate country-appropriate pandemic planning and<br />

vaccine policy development.<br />

Objectives<br />

The most efficient process for producing high-quality<br />

epidemiologic data for influenza-associated illness is sentinel<br />

surveillance. The primary limitation of most existing influenza<br />

sentinel-site networks that track ILIs has been that they often<br />

provide little epidemiologic data, do not produce data on disease<br />

incidence, and are focused on mild disease, which supports the<br />

notion that influenza is a benign disease. We propose that<br />

influenza surveillance should capture severe influenza outcomes<br />

as a primary measure. <strong>Hospital</strong>-based sentinel surveillance is the<br />

most efficient way to collect clinical data and laboratory specimens<br />

from persons with a prevalent and severe infectious disease.<br />

Carefully placed sentinel sites can provide adequate information<br />

on the epidemiology of influenza without the need for<br />

comprehensive national case ascertainment or reporting.<br />

Placing surveillance sites where population data are known<br />

would permit calculation of population-based estimates of disease<br />

rates according to age and other demographic variables. In<br />

addition, collection of clinical specimens from persons from whom<br />

epidemiologic data are also collected would ensure virus strain<br />

surveillance and provide isolates that can be used for vaccine<br />

development. A sentinel surveillance system can be used to<br />

monitor >1 disease, can be sustainable, and can integrate with<br />

and build upon existing systems. The system objectives are 1)<br />

describe the disease impact and epidemiology of severe, acute,<br />

febrile respiratory illness and define the proportion that is<br />

associated with influenza; 2) provide influenza virus isolates for<br />

monitoring changes in viral antigens and development of new<br />

vaccines; 3) contribute data for local pandemic planning and<br />

making decisions regarding vaccine policy; 4) provide<br />

infrastructure for an early warning system for outbreaks of new<br />

subtypes of influenza A viruses and new strains of existing<br />

subtypes; and 5) serve as a monitoring tool for pandemic influenza.<br />

Components and processes<br />

Case definitions<br />

These surveillance guidelines use the existing WHO case definition<br />

for ILI and incorporate WHO guidance to define SARI in adults and<br />

children (Table 1). The case definitions fit within the existing<br />

framework for pandemic early warning, use existing definitions for<br />

ease of adoption, and rely on physical examination findings that do<br />

not require laboratory or radiographic criteria. In addition, SARI<br />

definitions may capture a broad spectrum of severe influenzaassociated<br />

illness, including exacerbations of asthma, chronic<br />

obstructive pulmonary disease, and decompensated congestive<br />

heart failure, which may account for ≈75% of hospitalized influenza<br />

patients 16,20,21 .<br />

Sentinel site selection<br />

Ideally, sites should represent a wide cross-section of ethnic and<br />

socioeconomic groups and should be in different climatic regions.<br />

Placement of sites in areas where the population denominator can<br />

be ascertained or estimated will facilitate incidence estimates.<br />

Ultimately, the choice of sentinel hospitals will often be based on<br />

practical issues such as human resources, communication<br />

infrastructure, and availability of specimen transport and testing.<br />

There is no ideal number of surveillance sites; the number chosen<br />

by a particular country will depend in part on sustainability and<br />

resources available.<br />

Data Collection<br />

Minimum data elements are outlined in Table 2. Data collected<br />

should be adequate for routine public health surveillance and<br />

description of key epidemiologic features of disease. Data can be<br />

broadened to include clinical signs and symptoms, potential<br />

exposures, laboratory data, and therapies.<br />

Specimen collection<br />

Respiratory specimens should be collected early from all SARI<br />

patients, following established protocols 24 . If resources do not<br />

allow collection from all patients, an unbiased systematic sampling<br />

scheme should be established. To develop quality estimates of<br />

incidence and severity, data and specimens from all or most SARI<br />

patients from a few facilities would be preferred over a small<br />

sample of SARI patients from multiple facilities.<br />

Because seasonality, attack rates, and public health priorities<br />

differ from country to country, there is no generic number of<br />

specimens to be collected by each site. The number must be<br />

determined by the primary surveillance objective (e.g.,<br />

understanding of seasonality, risk factor analysis, or determination<br />

of clinical outcomes) and must represent climatic and geographic<br />

regions. For example, a country with coastal, mountainous, and<br />

tropical regions may have different influenza activity in each region<br />

and may thus require more surveillance sites and increased<br />

specimen collection than neighbors or similarly sized countries.<br />

Therefore, the number of specimens collected must be<br />

approached on a case-by-case basis and depends on objectives<br />

of a country, country-specific geographic and climatic issues, and<br />

public health priorities.<br />

Integration into national reporting systems<br />

In countries with established national disease reporting systems,<br />

such as the Integrated Disease Surveillance Reporting system<br />

used in Africa 25 , sentinel surveillance for SARI can be incorporated<br />

into the existing system. Because Integrated Disease Surveillance<br />

Reporting is generally a passive surveillance program, a few select<br />

sites should serve as embedded sentinel sites; intensive training<br />

and close follow-up should be conducted to ensure the quality of<br />

Innovation and policy: disease surveillance<br />

the reported data.<br />

Outpatient surveillance<br />

The highest priority should be to collect data on SARI cases<br />

because they contain the most influenza-associated disability and<br />

premature death. However, if resources permit, data collection at<br />

sentinel sites should be expanded to include ambulatory patients<br />

with ILI. Because the number of cases at ambulatory care sites is<br />

likely to be large, case counts would be aggregated, and clinical<br />

specimens and epidemiologic data would be collected from only a<br />

small sample of patients. Weekly case counts should be<br />

categorized by age group according to well-studied age-range<br />

categories (6–23 months, 2–4 years, 5–17 years, 18–49 years,<br />

50–64 years, and >65 years) 26 . Patients chosen to give detailed<br />

epidemiologic data and clinical specimens should be selected in<br />

as unbiased a manner as possible. The selection protocol must<br />

take into account local health-seeking behavior, such as<br />

differential use of evening and weekend clinics. Ideally, the weekly<br />

total number of patients seen by clinics would also be collected by<br />

age group to allow for proportion of ILI to be calculated. Rapid<br />

system expansion can compromise the quality of collected data;<br />

therefore, ILI surveillance should emphasize quality data collection<br />

from a few well-run sites.<br />

Laboratory testing<br />

Clinical specimens should be collected from a high proportion of<br />

SARI patients and a systematic sample of ILI patients. These<br />

specimens can be processed in sentinel site laboratories, but<br />

further analyses may require their transport to additional<br />

laboratories. Ideally, specimens would be tested for evidence of<br />

influenza viruses by reverse transcription–PCR (RT-PCR). A subset<br />

of specimens should undergo viral culture and antigenic<br />

characterization. Surveillance data should be submitted to WHO<br />

FluNet, and, if possible, national laboratories should work with a<br />

WHO Collaborating Center laboratory to submit sample virus<br />

isolates for vaccine strain selection.<br />

In countries where influenza spreads in seasonal epidemics, it<br />

may be adequate to collect less epidemiologic data and fewer<br />

specimens for laboratory testing by sampling a smaller proportion<br />

of SARI patients during the noninfluenza season. Knowledge of<br />

SARI rates outside influenza season will permit comparisons<br />

between peak season and baseline rates. Non–influenza season<br />

rates of SARI can also be monitored by public health authorities,<br />

because anomalies in SARI rates could represent outbreaks in<br />

need of investigation. However, high-quality, year-round data will<br />

be required for >1 season before assumptions can be made about<br />

seasonality in a region.<br />

Nasal and nasopharyngeal specimens have a higher yield for<br />

influenza virus detection in ILI cases than do oropharyngeal<br />

specimens 27 . However, the relative sensitivity of nasal versus<br />

oropharyngeal swabs to detect influenza virus infection in SARI<br />

cases is unknown. If both are collected, specimens can be placed<br />

in the same tube of viral transport media for processing. If SARI<br />

patients are intubated, endotracheal aspirates can also be used.<br />

Specimens can be frozen at –70°C for storage and possible future<br />

assessment of other respiratory pathogens.<br />

The sensitivity and specificity of any test for influenza will depend<br />

on the laboratory performing the test, the quality of the clinical<br />

specimen, the manner in which the specimen is processed, and<br />

the type of specimen collected. Generally, RT-PCR testing of<br />

respiratory specimens is the most sensitive laboratory test for<br />

influenza virus, but it is relatively expensive and is not useful for<br />

antigenic characterization 28 . If the proper primers and probes are<br />

used, RT-PCR can determine influenza virus A subtype and can<br />

detect novel influenza virus A subtypes. Fluorescent antibody<br />

tests, although less expensive, are less sensitive and specific than<br />

RT-PCR 27 . Rapid point-of-care tests are less sensitive and specific<br />

than RT-PCR or fluorescent antibody tests and are not generally<br />

recommended for use by sentinel surveillance. Virus culture has<br />

been the diagnostic standard for identifying influenza virus. Culture<br />

sensitivity depends on proper specimen handling and the<br />

experience of the laboratory. Virus culture should be performed on<br />

at least a sample of specimens to provide material for antigenic<br />

determination and potential isolates for vaccine production.<br />

Data analysis and reporting<br />

Timely analysis and reporting of surveillance data will facilitate<br />

treatment decisions by clinicians and control measures by public<br />

health officials. It will also encourage continued reporting of cases<br />

by clinicians in the surveillance system. Weekly reports of clinical<br />

and laboratory confirmed case counts should be disseminated<br />

throughout the surveillance system to participating healthcare<br />

providers and all stakeholders during peak seasons. The<br />

frequency of reports and the extent to which they are<br />

disseminated will depend on data timeliness and public health<br />

priorities. Sentinel surveillance reporting mechanisms should use<br />

existing public health communications systems and augment<br />

other reporting mechanisms such as FluNet through WHO GISN 29 .<br />

Basic analyses of surveillance data should include weekly<br />

frequencies of SARI and laboratory-confirmed influenza cases as<br />

well as the proportion of tested patients, by age group, who are<br />

influenza virus positive. If possible, proportions of SARI and<br />

influenza cases per total of weekly sentinel hospital admissions<br />

should be reported. Reports with case frequencies and<br />

proportions during prior weeks and years will demonstrate trends<br />

over time. At least once annually, analyses of surveillance data to<br />

determine risk factors for disease should be reported. These<br />

reports should use collected data on concurrent conditions and<br />

populationbased rates, if these can be determined.<br />

Understanding the epidemiology of severe influenzaassociated<br />

disease is essential for decisions related to vaccine<br />

recommendations. These data are prioritized in the guidelines<br />

because many developing countries have limited funds and<br />

competing healthcare priorities. However, data collected during<br />

SARI surveillance alone will be inadequate to describe aspects of<br />

influenza epidemiology such as transmission dynamics, costs, and<br />

occurrence of mild disease.<br />

Evaluation and auality assurance<br />

The usefulness of surveillance data will depend directly on the<br />

quality of the data; every system should have a quality assurance<br />

program. Quality indicators will reflect such attributes as system<br />

acceptability, timeliness, completeness, and representativeness of<br />

collected data. These attributes should be assessed routinely. In<br />

addition, the system should undergo regular data audits and<br />

systematic field evaluation. In 2001, the Centers for Disease<br />

Control and Prevention published comprehensive guidelines for<br />

the evaluation of public health surveillance systems 30 .<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 31


Innovation and policy: disease surveillance<br />

These guidelines serve as a template for sentinel surveillance<br />

evaluation and quality recommendations. Several key quality<br />

indicators are recommended in the following section and in Table 3.<br />

Data validity<br />

Regular field evaluations and audits at a facility level must be a<br />

standard component of the system. This process can determine<br />

that cases are being counted appropriately, that reported cases<br />

meet the case definition, and that sampling procedures are being<br />

used uniformly without evidence of bias. Data values recorded in<br />

the surveillance system can be compared with standard chartreview<br />

values by a retrospective review of a sample of medical<br />

records. If a sampling procedure is used for specimen collection,<br />

audits can ensure that procedures are uniform and unbiased.<br />

Additionally, audits can determine whether clinical specimens are<br />

being taken, stored, processed, tested (if appropriate), and<br />

shipped properly and in a timely manner from all those who meet<br />

sampling criteria.<br />

Observance of expected trends in reporting and disease activity<br />

can provide an additional means of assessing data quality.<br />

Although it is not possible to define expected values for some<br />

parameters, such as the percentage of specimens testing positive<br />

for influenza virus or the number of SARI cases occurring in a<br />

given facility, aberrations in the data over time or substantial<br />

differences between facilities can signal problems at a given site.<br />

Trends assessed may include number of cases reported by<br />

month, number of specimens submitted by month, percentage of<br />

influenzapositive specimens, and number and percentage of SARI<br />

and ILI cases tested.<br />

Timeliness<br />

To be useful, collection and reporting of surveillance data must be<br />

timely. Timeliness of the following activities is appropriate for<br />

routine measurement as quality indicators for surveillance sites:<br />

data reporting, specimen shipment to the laboratory for testing,<br />

receipt of specimens by the laboratory, laboratory processing and<br />

testing of specimens, and reporting of laboratory results.<br />

One way to quantify timeliness is to calculate the percentage of<br />

times that a site achieves targets for specific intervals, for example,<br />

the percentage of times that a site sends reports or specimens to<br />

the appropriate place within a specified time frame. A hypothetical<br />

system may choose as a goal that 80% of data reports be sent<br />

within 48 hours of the reporting deadline or that 80% of specimens<br />

be shipped within 48 hours of specimen collection. Likewise, for<br />

the laboratory, the percentage of samples that are tested and have<br />

final results within a target time frame can be calculated. Targets<br />

will depend on site-specific circumstances and public health<br />

priorities.<br />

A similar quality metric that can be used is the calculation of the<br />

average time to accomplish surveillance activities. For example, a<br />

hypothetical site that is chronically late in sending data every<br />

month might average several days between the deadline for<br />

receipt (the day of the week or month on which reports are due)<br />

and actual receipt of data. For laboratory specimen processing,<br />

the average number of days between receipt of specimens and<br />

the reporting of the results can be measured and followed similarly.<br />

Site time averages can be compared to identify sites that are<br />

underperforming and to target improvements. Either percentages<br />

of sites achieving timeliness targets or time lag averages can also<br />

Table 3: Influenza surveillance evaluation and recommended<br />

quality indicators*<br />

1. Timeliness<br />

a. Several time intervals are appropriate for routine<br />

measurement as quality indicators. These include the<br />

duration of time from<br />

i. Target date for data reporting from the sentinel site to the<br />

next administrative level until the actual reporting date<br />

ii. Target date for data reporting from the next<br />

administrative level to the national level until the actual<br />

reporting date<br />

iii. Date of specimen collection at facility until shipment to<br />

laboratory<br />

iv. Date of result availability in laboratory until date of report<br />

to referring institution and physician<br />

v. Date of receipt of specimen in the laboratory until result<br />

availability<br />

b. Metrics. Two metrics can be used to reflect timeliness<br />

indicators:<br />

i. Percentage of time that a site achieves target for<br />

timeliness<br />

ii. Average number of days for each interval over time for<br />

each site<br />

2. Completeness<br />

a. Percentage of reports received from each site with complete<br />

data<br />

b. Percentage of data reports that are received<br />

c. Percentage of reported cases that have specimens<br />

collected<br />

3. Audit. Regular field evaluations and audits at facility level of a<br />

subset of medical records to ensure<br />

a. Cases are being counted appropriately and not being<br />

underreported<br />

b. Reported cases fit the case definition<br />

c. Epidemiologic data are correctly and accurately abstracted<br />

d. Respiratory samples are being taken, stored, processed,<br />

tested, and shipped properly and in a timely fashion from all<br />

those who meet sampling criteria<br />

e. Sampling procedures are being done uniformly without<br />

evidence of bias<br />

4. Data to be followed and observed for aberrations over time<br />

a. Number of cases reported by month for each site<br />

b. Number of specimens submitted by month for each site<br />

c. Percentage of specimens that are positive for influenza<br />

d. Number and percent of ILI and SARI cases tested<br />

*ILI, influenza-like illness; SARI, severe acute respiratory illness.<br />

be used as a quality metric to be followed over time.<br />

Completeness<br />

Indicators of completeness can be determined by analyzing<br />

reported data. They may include percentage of reports received<br />

from each site with complete data, percentage of total expected<br />

data reports received, and percentage of total expected cases<br />

that have specimens submitted to the laboratory (depends on<br />

sampling scheme devised for sites).<br />

Pandemic early warning systems and monitoring<br />

Emergence of new subtypes of influenza virus A in human<br />

populations is unusual and unlikely to be detected by a sentinel<br />

surveillance system, except by chance or if transmission is<br />

sustained. Control of a pandemic caused by the introduction of a<br />

32 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and policy: disease surveillance<br />

new subtype of influenza virus A will require early detection and<br />

recognition of the event. Although sentinel surveillance as a standalone<br />

system may not accomplish this, it has value in establishing<br />

the infrastructure necessary to respond to a pandemic. In addition<br />

to providing a basic understanding of the epidemiology of<br />

influenza transmission and risk, a routine reporting system would<br />

produce an infrastructure for reporting, specimen processing and<br />

testing, and data collection and analysis. It would make data<br />

interpretation more routine (and thus more manageable in the face<br />

of a pandemic emergency) and drive interest in influenzaassociated<br />

disease and vaccination.<br />

After a novel strain of influenza emerges, monitoring its course<br />

is necessary to determine whether cases are increasing or<br />

decreasing, to detect changes in patient age distribution or other<br />

epidemiologic characteristics, to detect changes in mortality rates,<br />

and to monitor changes in susceptibility to antiviral agents. In the<br />

midst of an outbreak, national monitoring may not be necessary or<br />

feasible, and most, if not all, critical information can be gained from<br />

a few sentinel sites. Emergence of a new strain of influenza<br />

increases the data needs of health policy makers. Historical<br />

surveillance data for comparison can facilitate the understanding<br />

of answers to critical questions such as severity of the outbreak<br />

related to a new strain and its potential to adversely affect<br />

healthcare delivery. An existing surveillance infrastructure also<br />

provides the platform needed to describe the clinical course of<br />

emerging pathogens, risk factors for severe outcomes, and<br />

effectiveness of control measures.<br />

Conclusions<br />

Surveillance for SARIs can provide critical understanding of the<br />

contribution of influenza infection to the global burden of disease,<br />

provide a platform for the study of other common respiratory<br />

pathogens, and strengthen public health infrastructure. Such a<br />

system should be a part of a routine surveillance program to<br />

provide data needed for allocation of scarce healthcare<br />

resources. ❏<br />

Since its widespread introduction, the hepatitis B vaccine has become an essential part of infant immunization programmes<br />

globally. The vaccine has been particularly important for countries where the incidence of hepatitis B virus-related<br />

hepatocellular carcinoma is high. Effective treatment options for individuals with chronic hepatitis B infection were limited<br />

until 1998 when lamivudine, the first nucleoside analogue drug, was introduced. As a single treatment agent, however,<br />

lamivudine has a significant drawback: it induces lamivudine-resistant hepatitis B virus strains that may pose a risk to the<br />

global hepatitis B immunization programme. Mutations associated with drug treatment can cause changes to the surface<br />

antigen protein, the precise part of the virus that the hepatitis B vaccine mimics. However, the emergence of antiviral drug<br />

associated potential vaccine escape mutants (ADAP-VEMs) in treated patients does not necessarily pose a significant,<br />

imminent threat to the global hepatitis B immunization programme. Nonetheless, there is already evidence that current<br />

treatment regimens have resulted in the selection of stable ADAP-VEMs. Treatment is currently intended to prevent the longterm<br />

complications of hepatitis B virus infection, with little consideration given to potential adverse public health impacts.<br />

To address individual and public health concerns, trials are urgently needed to find the optimal combination of existing<br />

drugs that are effective but do not induce the emergence of ADAP-VEMs. This paper examines the mechanism of antiviral<br />

drug-selected changes in the portion of the viral genome that also affects the surface antigen, and explores their potential<br />

impact on current hepatitis B immunization programmes.<br />

Since its widespread introduction in 1983, the hepatitis B<br />

vaccine has become an essential part of infant<br />

immunization programmes globally, and is the key<br />

component of the global hepatitis B control programme for the<br />

World Health Organization. 1 Infection with hepatitis B virus (HBV)<br />

can cause acute liver disease, as well as chronic infection that may<br />

lead to liver failure or hepatocellular carcinoma. The vaccine has<br />

been particularly important for countries where the incidence of<br />

HBV-related hepatocellular carcinoma is high. In effect, the<br />

hepatitis B vaccine was the world’s first anticancer vaccine.<br />

Effective treatment options for individuals with chronic hepatitis<br />

B infection were limited until 1998 when lamivudine, the first<br />

nucleoside analogue drug, was approved for treatment. Newer<br />

agents have been developed, but lamivudine remains the<br />

mainstay therapy in many countries with high HBV prevalence<br />

because of its safety, efficacy and low cost. As a single treatment<br />

agent, however, lamivudine has a significant drawback:<br />

monotherapy has resulted in the appearance of lamivudineresistant<br />

HBV strains, a phenomenon that has been observed with<br />

single-drug regimens used to treat other infections such as<br />

tuberculosis and human immunodeficiency virus (HIV) infection. 2<br />

The emergence of these drug-resistant strains limits therapeutic<br />

options for individuals chronically infected with HBV; moreover, the<br />

spread of these strains may pose a risk to the global hepatitis B<br />

immunization programme. Mutations associated with drug<br />

treatment can cause changes to the surface antigen protein, the<br />

precise portion of the virus that the hepatitis B vaccine mimics.<br />

This article examines the mechanism of antiviral drug-selected<br />

changes in the part of the viral genome that also affects the<br />

surface antigen, and explores their potential impact on current<br />

hepatitis B vaccine programmes (Box 1).<br />

Features of the hepatitis B virus<br />

HBV is an enveloped, partly double-stranded DNA virus<br />

containing a compact, circular genome of overlapping reading<br />

frames (Figure 1). Human HBV causes both acute and longterm<br />

infections, including chronic and neoplastic liver disease. The virus<br />

exists as eight genotypes labelled A to H, with varied geographical<br />

34 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: hepatitis B<br />

distributions. Differences between genotypes involve<br />

approximately 8% of the genomic sequence. 3–5 HBV uses an<br />

encoded enzyme reverse transcriptase to replicate its viral<br />

genome. Reverse transcription is an error-prone process that<br />

generates a large number of nucleotide changes within the viral<br />

genome. This process results in new, closely-related viral species;<br />

as a result, at any given time in a particular host the viral population<br />

consists of a swarm of similar but discrete viruses. 6,7<br />

Hepatitis B vaccine escape mutants<br />

The hepatitis B vaccine is an effective means of preventing HBV<br />

infection, producing protective levels of antibodies in up to 95% of<br />

recipients. 8 The envelope gene of HBV produces proteins of three<br />

different lengths: two larger proteins, preS1 and preS2, as well as<br />

the smaller S protein. The commercially available hepatitis B vaccine<br />

used in most programmes is a yeast-derived recombinant surface<br />

antigen of the small S protein alone. Antibodies elicited by the<br />

hepatitis B vaccine specifically target the “a” determinant of the<br />

surface antigen (Figure 1). It has been recognized that the<br />

administration of hepatitis B vaccine can increase the mutation rate<br />

of the virus. In high-prevalence countries such as China, Thailand<br />

and Taiwan, monitoring for more than a decade has shown that<br />

hepatitis B immunization programmes have increased the incidence<br />

of HBV variants with mutations in the surface antigen protein 9,10 even<br />

as they reduce the overall burden of chronic hepatitis B infection. 11<br />

Mutations in and around the “a” determinant may lead to an<br />

alteration in the antigenicity of the surface antigen protein so that<br />

antibodies directed against the surface antigen protein may fail to<br />

neutralize the virus. 12–20 Infection of immunized individuals with a<br />

vaccine escape mutant (VEM) 20 is therefore possible. VEMs are<br />

typically characterized by the presence of single-amino-acid<br />

changes in the S protein. 12,21 Some of these variants are associated<br />

with high levels of viraemia and have persisted in the host for more<br />

than 10 years, suggesting they are stable and transmissible variants.<br />

In addition, the antibody responses against the surface antigen<br />

protein elicited by the recombinant yeast-derived vaccine now in use<br />

are weaker and more specific than those achieved with the previous<br />

plasma-derived surface antigen vaccine. 22–24 In Taiwan, up to 28% of<br />

children with chronic hepatitis B infection also harbour hepatitis B<br />

surface antigen mutants. So VEMs capable of causing infection in<br />

fully immunized individuals are not uncommon in countries with high<br />

rates of endemic HBV infection and universal hepatitis B infant<br />

immunization programmes. 12,20 However, to date the emergence of<br />

VEMs has not had a known negative impact on any country’s<br />

immunization programme. 25<br />

Treatment of HBV infection<br />

Five oral antiviral agents have been approved by the United States<br />

Food and Drug Administration for the treatment of chronic<br />

hepatitis B infection: lamivudine, adefovir, entecavir, telbivudine<br />

and tenofovir. 26,27 The same agents are licensed in the United<br />

Kingdom and Europe. Each of these nucleoside analogue drugs<br />

has an excellent safety and efficacy profile. Effective long-term<br />

suppression of HBV replication by these agents is associated with<br />

histological and clinical improvement. Before the approval of these<br />

direct antiviral agents, interferon, an immune potentiator, had been<br />

used to treat chronic hepatitis B infection. 28 However, interferon<br />

was not consistently successful when used as monotherapy. 26,27<br />

More recently, standard interferon has been replaced by interferon<br />

with PEG-IFN alone. However, compared with lamivudine<br />

monotherapy, this combination was more effective in preventing the<br />

emergence of lamivudine-resistant HBV. 31 The combination of PEG-<br />

entecavir or tenofovir needs to be tested.<br />

frames that overlap each other. As a consequence of this<br />

arrangement, the part of the polymerase gene that codes for the<br />

reverse transcriptase enzyme – the target of antiviral therapy –<br />

overlaps the neutralization domain of the surface gene that codes<br />

for the S protein – the target of antibodies elicited by the hepatitis<br />

B vaccine (Figure 1). Treatment of HBV-infected individuals with<br />

nucleoside analogues results in mutations in the polymerase gene,<br />

many of which are associated with alterations in the “a”<br />

determinant of the surface antigen. 32–34 Resistance to lamivudine is,<br />

in fact, common in patients on monotherapy, appearing in from<br />

15% after the first year of treatment to 67% when used<br />

continuously for 4 years. 35 The genomic changes can be stable,<br />

and in at least one case a drug-resistant strain has been<br />

transmitted to another individual. 36 Consequently, in populations<br />

where lamivudine has been widely used to treat patients<br />

continuously for periods of several years, viruses with alterations in<br />

the surface antigen are likely to occur relatively frequently, and<br />

some will be antiviral drug-associated potential vaccine escape<br />

mutants (ADAP-VEMs). Although drug-driven changes in the S<br />

protein have been well described, the effect of these changes on<br />

the antigenicity of the surface antigen has been little studied. 37,38<br />

Public health risk of escape mutants<br />

The use of nucleoside and nucleotide analogues in the treatment<br />

of chronic hepatitis B infection results in mutations in the<br />

HBV genome that can have an impact on public health (Fig.<br />

2). However, the emergence of such ADAP-VEMs in treated<br />

patients does not necessarily pose a significant, imminent<br />

threat to the global hepatitis B immunization programme. For<br />

instance, some ADAP-VEMs selected by lamivudine have<br />

been shown to be less fit virologically; that is, they are rapidly<br />

replaced when the drug is removed and are unlikely to be a<br />

dominant or co-dominant viral population in terms of virus<br />

transmission. 29 For a new viral species to pose a threat to an<br />

immunization programme, we propose that it must display<br />

the following characteristics: (i) it must be a stable mutant, (ii)<br />

the changes in antigenicity must be sufficient to prevent the<br />

antibody generated by the vaccine from neutralizing it (i.e. it<br />

must be a true ADA-VEM), (iii) it must be transmissible,<br />

cause infection in immunized individuals and have<br />

opportunities to spread and (iv) it must cause acute or<br />

chronic disease in infected individuals. Of these four<br />

characteristics, to date we have evidence that three have<br />

been fulfilled, although we do not know if ADAP-VEMs have<br />

the same propensity to cause disease as do strains of HBV<br />

that are already circulating. However, given the high rate of<br />

HBV drug resistance and the discovery of ADAP-VEMs in<br />

individuals who have received lamivudine therapy, we<br />

suggest at least two features of HBV treatment programmes<br />

may increase the likelihood that an ADAP-VEM of public<br />

health importance will emerge. The first feature of such<br />

programmes that can increase the risk is the type of antiviral<br />

agent. Lamivudine, although it is relatively inexpensive, has<br />

been shown to rapidly result in the selection of primary<br />

antiviral drug-resistant polymerase variants.<br />

These variants in turn also select for compensatory<br />

mutations, some of which may have altered surface<br />

antigens. 33,34,39 In contrast, the likelihood that mutants will be<br />

generated seems to be much lower for newer agents such<br />

as entecavir, and for combination therapies including PEG-IFN,<br />

although the risk is not zero. 30,35,38,40 All of these newer medications,<br />

however, are more expensive and their long-term efficacy is still<br />

being established. Consequently, for the foreseeable future many<br />

countries, especially in the Asia-Pacific region, will probably<br />

continue to treat chronic hepatitis B infection with lamivudine even<br />

though it is no longer considered the first-line treatment, and<br />

despite the fact that drug resistance may rapidly emerge. 41 The<br />

proliferation of medications and substandard drugs, as has<br />

occurred with treatments for malaria (for instance), is an additional<br />

risk as treatment programmes expand in developing countries.<br />

The second potentially problematic feature of current treatment<br />

programmes is the way patients are selected. Antiviral drugs are<br />

the only long-term treatment option for chronic hepatitis B<br />

infection, 40 and many investigators have argued that all patients<br />

who are viraemic should be treated. Because of the strong<br />

correlation between HBV viral load and the likelihood of developing<br />

cirrhosis and hepatocellular carcinoma, reducing viral replication<br />

as early as possible after infection is likely to be beneficial. In<br />

addition to being costly, this approach may generate antiviral drug<br />

resistance since current agents never lead to eradication of the<br />

virus, but only to control of replication. This effect, in turn, can<br />

complicate second-line therapies and may favour the appearance<br />

of ADAPVEMs. Treatment in industrialized countries is therefore<br />

Innovation and clinical specialities: hepatitis B<br />

usually reserved for patients likely to respond to therapy and those<br />

who have advanced disease. 41 However, there is no consensus<br />

globally regarding which patients to treat, and WHO has not yet<br />

produced international recommendations to guide therapy (Daniel<br />

Lavanchy, personal communication, 2008). Inappropriate inclusion<br />

criteria, improper application of these criteria or lack of compliance<br />

with treatment could greatly influence the emergence of both drug<br />

resistance and ADAP-VEMs. The public health risk of treatment<br />

programmes in different populations may also depend upon<br />

features of the circulating viral genotype. There is evidence that the<br />

genotype of the virus influences the speed and frequency of<br />

development of resistance to treatment, which may in turn<br />

influence the likelihood that ADAP-VEMs will emerge. For<br />

example, genotype A-1 (common in northwestern Europe and<br />

North America) more frequently develops surface protein changes<br />

with lamivudine therapy than genotype D-1 (concentrated in<br />

Mediterranean countries but distributed globally). 42 The viral<br />

genotype also influences how frequently infected individuals<br />

develop antibodies to the hepatitis B “e” antigen (HBeAg). During<br />

the natural history of chronic hepatitis B, persons infected with<br />

genotype D-1 are more likely to become HBeAg-negative than<br />

those infected with genotype A-1. 43 In general, when HBeAg is<br />

detectable in the blood, the infection is more transmissible. Among<br />

children born to mothers who are HBeAg-positive, 90% will<br />

become infected whereas only 10% of children born to HBeAgnegative<br />

mothers will become infected. The disease process can<br />

also be more active and more rapidly progressive in HBeAgpositive<br />

individuals, 43 although disease progression may also be<br />

influenced more by the underlying HBV genotype than by HBeAg<br />

status alone. 44,45 The proportion of infected individuals who are<br />

HBeAg-positive could therefore influence the total numbers of<br />

persons treated with antiviral medications, the risk of generating<br />

ADAPVEMs and the subsequent risk of secondary transmission of<br />

these mutants. Given these features, the likelihood that escape<br />

mutants will emerge as a result of HBV treatment programmes is<br />

probably greatest in settings of high HBV prevalence, where<br />

treatment is widely available and where regimens are inappropriate<br />

or adherence is uneven. Escape mutants may also appear in<br />

settings where HIV/HBV co-infection is prevalent since HIV is<br />

known to increase HBV replication, 46 but it has not been confirmed<br />

that co-infection alters the rate of developing resistance. Within<br />

these settings there may be subgroups of particular interest. For<br />

example, the efficiency of transmission from an HBeAg-positive<br />

mother to her child during the perinatal period creates a very high<br />

risk for chronic hepatitis B infection. This risk makes it important to<br />

monitor for ADAP-VEMs among treated women of childbearing<br />

age, especially if lamivudine is used as monotherapy, since neither<br />

hepatitis B immunoglobulin nor active immunization would prevent<br />

infection with an ADAP-VEM transmitted from mother to child. In<br />

addition, the child may then spread the ADAP-VEM to other<br />

children, immunized or not. Subsequent treatment of chronic<br />

hepatitis B in all persons infected when young is also complicated<br />

if they have been infected with a drug-resistant strain. On the other<br />

hand, it has been estimated that the proportion of all HBV<br />

infections acquired among children more than 5 years of age<br />

ranges from 10% where prevalence of hepatitis B infection is high<br />

to as much as 90% where prevalence is low. 47 These numbers<br />

suggest that monitoring for ADAP-VEMs may be needed in other<br />

populations in addition to HBVinfected HBeAg-positive women of<br />

childbearing age. Geographical sites of high risk for the<br />

emergence of ADAP-VEMs of public health importance should be<br />

mapped. To this end, official and unofficial treatment programmes<br />

that already record the type of antiviral treatment, treatment criteria<br />

and the extent of substandard medications could be combined<br />

with descriptive epidemiology (e.g. high burden of disease, viral<br />

genotype, proportion of HBV-infected individuals with surface<br />

antigen positivity) to identify high-risk settings.<br />

Discussion<br />

In this article we raise the possibility of a threat to the global<br />

hepatitis B immunization programme because of the use of<br />

lamivudine and other nucleoside or nucleotide analogue<br />

therapeutic agents to treat individuals with chronic hepatitis B<br />

infection. Although the threat is theoretical, there is already<br />

evidence that current treatment regimens have resulted in the<br />

selection of stable ADAP-VEMs. Even though the transmission of<br />

ADAPVEMs to individuals immunized with HBV vaccine has been<br />

observed in only one case, 36 VEMs generated by hepatitis B<br />

vaccine have spread more widely and caused infection in<br />

previously immunized individuals.<br />

Knowing this, what should our response be now? At the very<br />

least, we must learn more about ADAP-VEMs, their transmissibility<br />

and their potential to cause infection and disease in immunized<br />

individuals. This will require virological surveillance and clinical<br />

follow-up of infected individuals and those undergoing treatment,<br />

and also, possibly, surveillance of their close contacts. The initial<br />

focus of these activities should be highrisk settings until the level<br />

of risk is defined and understood better. Incident cases of HBV in<br />

these situations could also be examined for VEMs, especially if a<br />

new case is epidemiologically linked to an individual undergoing<br />

treatment for chronic hepatitis B infection. Follow-up of such<br />

cases of HBV, however, would depend on the availability of testing,<br />

and currently no suitable commercial tests are available.<br />

At present, treatment aims to prevent the long-term<br />

complications of HBV infection, with little consideration given to<br />

potential adverse public health impacts. The number of potent<br />

antiviral agents is limited, their development by manufacturers is<br />

episodic and trials that have evaluated combination therapies are<br />

lacking. Because of these factors, monotherapy remains the usual<br />

practice in most settings. As with other infections, more potent<br />

combination therapies for HBV would reduce the chance of<br />

drugresistance and lead to early and longer-lasting control of HBV<br />

replication. Such therapies would not only benefit the individual<br />

but would also simultaneously reduce the likelihood that ADAP-<br />

VEMs of global public health significance will emerge. Trials are<br />

urgently needed to identify the optimal combination of existing<br />

drugs that can address both individual and public health needs.<br />

<strong>International</strong> therapeutic guidelines for chronic hepatitis B such as<br />

those issued by the Asian-Pacific Association for the Study of the<br />

Liver, 48 the European Association for the Study of the Liver<br />

<strong>International</strong> Consensus Conference 49 and the American<br />

Association for the Study of Liver Disease 50 should ideally consider<br />

both of these elements, and will need to be refined as more is<br />

learned about ADAP-VEMs. More effective novel agents are clearly<br />

needed that target other parts of the virus.<br />

It is still essential to prevent the spread of wild, vaccine-sensitive<br />

strains of HBV. Well-tested measures such as safe sex and<br />

avoiding the risks associated with injection drug use will also help<br />

to reduce horizontal transmission of both the wild virus and VEMs.<br />

Hepatitis B immunization for infants of mothers with HBV will<br />

reduce perinatal transmission of the wild virus but may not prevent<br />

transmission of VEMs. The global hepatitis B immunization<br />

programme will continue to reduce new incident infections of<br />

hepatitis B and the burden of chronic HBV disease globally,<br />

although it is simultaneously generating VEMs. One simulation has<br />

predicted that the spread of VEMs selected out by immunization<br />

would result in relatively few new infections for the foreseeable<br />

future. 51 However, it is not yet clear whether the emergence of<br />

ADAP-VEMs in a population will be speeded up by the<br />

simultaneous use of both the vaccine and treatment. Of course,<br />

hepatitis B vaccines that incorporate HBV proteins not altered by<br />

immunization or drug therapy are the ultimate solution to prevent<br />

the appearance of viral escape mutants generated by vaccines or<br />

antiviral drugs. ❏<br />

Recent events clearly illustrate a continued vulnerability of large populations to infectious diseases, which is related<br />

to our changing human-constructed and natural environments. A single person with multidrug-resistant tuberculosis<br />

in 2007 provided a wake-up call to the United States and global public health infrastructure, as the health<br />

professionals and the public realized that today’s ease of airline travel can potentially expose hundreds of persons to<br />

an untreatable disease associated with an infectious agent. Ease of travel, population increase, population<br />

displacement, pollution, agricultural activity, changing socioeconomic structures, and international conflicts<br />

worldwide have each contributed to infectious disease events. Today, however, nothing is larger in scale, has more<br />

potential for long-term effects, and is more uncertain than the effects of climate change on infectious disease<br />

outbreaks, epidemics, and pandemics. We discuss advances in our ability to predict these events and, in particular,<br />

the critical role that satellite imaging could play in mounting an effective response.<br />

Atmospheric chemists and climate modelers have little doubt<br />

that the earth’s climate is changing. Concomitant with rising<br />

carbon dioxide levels and temperatures, severe weather<br />

events are increasing, which can lead to substantial rises in sea<br />

level, flooding, increased droughts, and forest fires 1 . In recent<br />

decades, infectious diseases have resurged, and previously<br />

unrecognized agents of disease have been characterized 2 .<br />

Evidence is accruing that these phenomena may in part be linked<br />

to environmental change 3 . Several questions have emerged from<br />

events that have occurred over the past 20 years: was<br />

cryptosporidiosis inevitable in Milwaukee, Wisconsin, USA, in<br />

1993, and was Escherichia coli O157 infection inevitable in<br />

Walkerton, Ontario, Canada, in 2000? Both events were preceded<br />

by heavy rains; had highly concentrated sources of pathogens in<br />

the form of untreated sewage and animal waste, respectively; and<br />

had vulnerable infrastructure. Although the situations were<br />

perhaps more complex, could we have predicted epidemic<br />

cholera in South America in 1991 after a 100-year absence and<br />

the emergence of a new strain of potentially pandemic cholera in<br />

India in 1992?<br />

A considerable body of knowledge has accumulated over the<br />

past decade or so about the relationships between environment<br />

and disease, yet far more information and resources are needed if<br />

we are to develop effective early warning systems through<br />

environmental surveillance and modeling as well as appropriate<br />

emergency response. In the United States, we face a crisis in<br />

funding that not only affects basic and applied research in this field<br />

but also undermines our ability to deploy remote sensing<br />

technologies that provide the most promising means for<br />

monitoring our environment. Using examples of waterborne and<br />

vectorborne disease, we will discuss how remote sensing<br />

technology can be used for disease prediction. We will then<br />

examine the lessons learned from these examples and provide<br />

recommendations for future modeling.<br />

Waterborne disease<br />

Water and climate go hand in hand, with precipitation and extreme<br />

events known to be associated with waterborne outbreaks 4 .<br />

Flooding is the most frequent natural weather disaster (30%–46%<br />

of natural disasters in 2004–2005), affecting >70 million persons<br />

worldwide each year (data for 2005 5 ).<br />

The most common illnesses associated with floods described in<br />

the literature are diarrhea, cholera, typhoid, hepatitis (jaundice),<br />

and leptospirosis. Unusual illnesses such as tetanus have also<br />

been reported. The etiologic agents identified include<br />

Cryptosporidium spp., hepatitis A virus, hepatitis E virus,<br />

Figure 1: Modeling cholera outbreaks in Bangladesh. Adapted from RR Colwell and<br />

J Calkins, unpub. data.<br />

Leptospira spp., Salmonella spp., and Vibrio spp. Severe<br />

outbreaks of cholera, in particular, have been directly associated<br />

with flooding in Africa and in West Bengal, India 6,7 .<br />

A rise in sea level, combined with increasingly severe weather<br />

events, is likely to make flooding events commonplace worldwide.<br />

The Climate Change 2001 Synthesis Report from the<br />

Intergovernmental Panel on Climate Change 8 suggests that the<br />

average annual numbers of persons affected by coastal storm<br />

surges will increase from 50% 10 .<br />

Although remote sensing technology is currently<br />

still a research tool, the example of cholera<br />

prediction through its use provides a compelling<br />

argument to maintain and adequately fund our<br />

satellite programmes; unless this is done, this<br />

extraordinary effort at disease prediction will fail. Some of the<br />

critical needs that must be met to predict the effect of<br />

environmental change on waterborne disease include the<br />

following:<br />

✚ better knowledge of disease incidence and pathogen<br />

excretion;<br />

✚ better characterization of the pathogens in sources (e.g.,<br />

combined sewer overflows, septic tanks) and these sources’<br />

vulnerabilities to climate change;<br />

✚ better monitoring of sewage indicators to gather source,<br />

transport, and exposure information (event monitoring);<br />

✚ improved understanding of sediments and other pathogen<br />

reservoirs;<br />

✚ more quantitative data for risk assessment; and<br />

✚ better health surveillance data. In turn, this information can be<br />

used to better use ground truthing in combination with remote<br />

sensing technologies as predictors of waterborne disease<br />

outbreaks.<br />

Using satellite technology to model prediction of Cholera<br />

outbreaks<br />

Effective prediction depends on many factors, not just the<br />

prediction of an event. Cholera may be the most studied and best<br />

understood of the waterborne diseases and, perhaps in hindsight,<br />

we could have predicted the occurrence of cholera in South<br />

America in 1991 9 . Models for cholera prediction, although country<br />

specific, are constantly improving. For example, considerable<br />

work has gone into predicting outbreaks of cholera in Bangladesh.<br />

Remote imaging technologies developed by the US National<br />

Aeronautics and Space Administration have been used to relate<br />

sea surface temperature, sea surface height, and chlorophyll A<br />

levels to cholera outbreaks (Figure 1) (RR Colwell and J Calkins,<br />

unpub. data). This process used a composite environmental<br />

model that demonstrated a remarkable similarity between<br />

predicted rates based on these three parameters and actual<br />

cholera incidence. These data are far from perfect and<br />

considerable uncertainty still remains. For example, rates of<br />

Vectorborne disease<br />

Other emerging and reemerging infectious diseases also are<br />

environmentally driven. Many are zoonotic, vector- 1342 Emerging<br />

borne, or both, and have complex life histories that make<br />

predicting disease emergence or reemergence particularly difficult.<br />

An insect or rodent vector can make it almost inevitable that a<br />

pathogen will be globally transported by plane or boat. With<br />

environmental change, disease range, prevalence, and seasonality<br />

may change in direct relationship to the vector or animal host.<br />

Therefore, to understand the life cycle of a pathogen and the risks<br />

of disease emergence, all stages of that life cycle and the life<br />

cycles of its intermediate hosts must be considered.<br />

To date, predicting vectorborne diseases has proved to be<br />

complex. Although climate change and other environmental<br />

stressors are major components, separation from human factors<br />

is difficult. Climate change undoubtedly affects the distribution of<br />

disease, but changes in human behaviour that increase exposure<br />

risk are also critical factors. Šumilo et al. 11 reported that climatic<br />

42 <strong>Hospital</strong> and healthcare Innovation Book 2009/2010


Innovation and strategy: infectious disease surveillance<br />

variables explain only 55% of spatial variation in tick-borne<br />

encephalitis in the Baltic States, which have seen an increase in<br />

disease incidence over the past 3 decades. These authors report<br />

that changes in predation pressure on intermediate hosts and<br />

shifting socioeconomic conditions that increase or decrease<br />

peoples’ visits to forests (for recreation, work, or berry and<br />

mushroom harvesting) are important factors in disease<br />

distribution 12 .<br />

Effective modeling of future risk for vectorborne disease<br />

outbreaks needs to take into account human behaviour that<br />

increases exposure, as well as other factors that effect the ecology<br />

of the vectors, such as predation pressure and habitat change.<br />

Coupled with remote sensing technologies that monitor<br />

environmental and climatic changes, human observations of<br />

population movement and distribution will be necessary.<br />

Malaria also presents a challenge. This disease continues to<br />

devastate sub-Saharan Africa and other parts of the developing<br />

world. Substantial resources over the past several decades have<br />

gone toward eradication, vaccination, treatment, and, more<br />

recently, prediction of malaria outbreaks. Satellite imaging has<br />

been used to predict the distribution of 5 of the 6 Anopheles<br />

gambiae complex species that are responsible for much of the<br />

malaria transmission in Africa 13 . However, human factors again<br />

make accurate prediction of disease events complex. Prediction of<br />

a disease event is complicated by host immunity effects, which<br />

can result in cycles of infection that would appear to bear no<br />

relationship to environmental variables.<br />

To predict malaria outbreaks, remote sensing technologies need<br />

to be coupled with a better understanding of how specific<br />

populations are effected by host immunity, which could allow<br />

population susceptibility at any given time to be estimated.<br />

Using satellite technology to model Hantavirus Pulmonary<br />

Syndrome<br />

Although considerable uncertainty exists in disease prediction<br />

through remote sensing technology, particularly for vectorborne<br />

disease as discussed above, satellite technology has been applied<br />

with some success to predictive modeling for cases of hantavirus<br />

pulmonary syndrome (HPS). The 1993 outbreak of HPS in the<br />

southwestern United States was believed to be linked to<br />

environmental conditions and, in particular, to abnormally high<br />

rainfall that resulted in increased vegetation with a subsequent<br />

explosion in the rodent populations. Several research groups have<br />

subsequently modeled conditions that led to an HPS outbreak,<br />

with mixed success. Engelthaler et al. 14 looked at 10 years of data<br />

on monthly precipitation and daily ambient temperature in the<br />

Southwest region (1986–1995) in relation to HPS cases<br />

(1993–1995). They found that cases tended to cluster seasonally<br />

and temporally by biome type and elevation and only indirectly<br />

demonstrated a possible association between the 1992/1993 El<br />

Niño precipitation events and HPS. Glass et al. 15,16 were also<br />

unable to make a definitive link with precipitation events in their<br />

analyses of HPS in the southwestern United States. They did,<br />

however, find a relationship between Landsat Thermatic Mapper<br />

(LTM) images recorded by satellite in 1992 and HPS risk the<br />

following year. LTM generates numbers that represent reflected<br />

light in 6 bands, 2 of which were associated with decreased risk<br />

and 1, in the mid-infrared range, with increased risk. The authors<br />

admit that considerable ground truthing is necessary to relate<br />

satellite imagery to the environmental variables being measured<br />

(i.e., vegetation, soil type, soil moisture) and their relation to rodent<br />

population dynamics.<br />

However, this work does demonstrate the utility of remote<br />

satellite imaging and the increasingly important role it can and<br />

should play in disease prediction. In 2006, Glass et al. 17 reported<br />

strong predictive strength from logistic regression modeling of LTM<br />

imagery from one year, when estimating risk of HPS the following<br />

year, for the years 1992– 2005. Their risk analysis for 2006, based<br />

on Landsat imagery for 2005, when precipitation levels increased<br />

dramatically over prior drought years, suggested an increased risk<br />

for HPS, particularly in northern New Mexico and southern<br />

Colorado. This prediction was unfortunately borne out in the early<br />

part of 2006 when 9 cases of HPS occurred within the first 3<br />

months, 6 of those cases in New Mexico and Arizona. However,<br />

the anticipated threat to Colorado did not occur, with a fairly<br />

typical number of 6 cases, compared with a total of 11 cases for<br />

the state in 2005 18 .<br />

However, these results are not necessarily a failure of prediction.<br />

In fact, they may illustrate that an early warning system serves to<br />

reduce exposure of persons to the deermice habitat. For example,<br />

USA Today highlighted HPS risks with a June 8, 2006, article<br />

titled “Officials warn of increased threat of hantavirus”<br />

(www.usatoday.com/news/ health/2006-06-08-hantavirus-x.htm).<br />

The role of the popular press is hard to quantify but undoubtedly<br />

does have an effect on human behavior patterns. Many health<br />

departments in the western states produce health advisories<br />

warning the public about the risks of exposure to the virus through<br />

inhalation of dust contaminated with rodent urine, feces, or saliva.<br />

The popular press may serve an important role in increasing<br />

awareness of a heightened health risk, which, in turn, promotes<br />

greater compliance with health advisories.<br />

Lessons learned and recommendations for future modeling<br />

The scientific community has a relative consensus that epidemic<br />

and pandemic disease risks will be exacerbated by environmental<br />

changes that destabilize weather patterns, change distribution of<br />

vectors, and increase transport and transmission risk. Predictive<br />

modeling may lead to improved understanding and potentially<br />

prevent future epidemic and pandemic disease. Many respiratory<br />

infections are well known as highly climate dependent or seasonal.<br />

Although we are not yet able to predict their incidence with great<br />

precision, we may well be able to do this in the future.<br />

Meningococcal meningitis (caused by Neisseria meningitidis) in<br />

Africa is probably the best known example. In the diseaseendemic<br />

so-called meningitis belt (an area running across sub-<br />

Saharan Africa from Senegal to Ethiopia), this is classically a dry<br />

season disease, which ceases with the beginning of the rainy<br />

season, likely as a result of changes in host susceptibility 19 . Many<br />

other infectious diseases show strong seasonality or association<br />

with climatic conditions 20 . Perhaps one of the most interesting is<br />

influenza, which is thought of as a wintertime disease in temperate<br />

climates but shows both winter and summer peaks in subtropical<br />

and tropical regions 21 . Although the reasons for seasonality are<br />

often poorly understood, the close dependence of such diseases<br />

on climatic conditions suggests that these, too, are likely to be<br />

amenable to prediction by modeling and remote sensing 22 . When<br />

we consider influenza, it is hard not to think about the future risks<br />

from pandemic influenza. Public health agencies in the United<br />

States and around the world are focusing on influenza<br />

preparedness, notably concerning influenza virus A<br />

subtype H5N1, which has captured attention because<br />

it causes severe disease and death in humans but as<br />

yet has demonstrated only very limited and inefficient<br />

human-to-human transmission. The severity of the<br />

disease raises images of the 1918 influenza epidemic<br />

on an unimaginably vast scale if the virus were to adapt<br />

environmental variables help in prediction of future<br />

influenza pandemics? Xiangming Xiao at the University<br />

of New Hampshire was funded in 2006 by the National<br />

Institutes for Health to lead a multidisciplinary and<br />

multi-institutional team to use remote satellite imaging<br />

to track avian flu. Xiao et al. have used satellite<br />

image–derived vegetation indices to map paddy rice<br />

agriculture in southern Asia 23 . They believe that a similar<br />

approach can be used in conjunction with the more<br />

traditional approach of analyzing bird migration<br />

patterns and poultry production 24,25 to map potential hot<br />

spots of virus transmission 26 .<br />

An interesting question is why did we not see disease epidemics<br />

in Indonesia, following the devastating tsunami disaster of<br />

December 2004? Could rapid public health intervention be<br />

credited with minimizing spread of disease? In the case of Aceh<br />

Province, many communities reported diarrhea as the main cause<br />

of illness (in 85% of children


Innovation and strategy: infectious disease surveillance<br />

ability to accurately link environmental variables, particularly those<br />

related to climate change, will improve. What has become clear<br />

over the past few years is that satellite imaging can play a critical<br />

role in disease prediction and, therefore, inform our response to<br />

future outbreaks. We conclude that infectious disease events may<br />

be closely linked to environmental and global change. Satellite<br />

imaging may be critical for effective disease prediction and thus<br />

future mitigation of epidemic and pandemic diseases. We cannot<br />

stress too strongly our belief that a strong global satellite<br />

programme is essential for future disease prediction. ❏<br />

Free or low-cost sources of unstructured information, such as Internet news and online discussion sites, provide detailed local<br />

and near real-time data on disease outbreaks, even in countries that lack traditional public health surveillance. To improve<br />

public health surveillance and, ultimately, interventions, we examined three primary systems that process event-based<br />

outbreak information: Global Public Health Intelligence Network, HealthMap, and EpiSPIDER. Despite similarities among<br />

them, these systems are highly complementary because they monitor different data types, rely on varying levels of<br />

automation and human analysis, and distribute distinct information. Future development should focus on linking these<br />

systems more closely to public health practitioners in the field and establishing collaborative networks for alert verification<br />

and dissemination. Such development would further establish event-based monitoring as an invaluable public health<br />

resource that provides critical context and an alternative to traditional indicator-based outbreak reporting.<br />

<strong>International</strong> travel and movement of goods increasingly<br />

facilitates the spread of pathogens across and among nations,<br />

enabling pathogens to invade new territories and adapt to new<br />

environments and hosts. 1–3 Officials now need to consider<br />

worldwide disease outbreaks when determining what potential<br />

threats might affect the health and welfare of their nations 4 . In<br />

industrialized countries, unprecedented efforts have built on<br />

indicator-based public health surveillance, and monitoring of<br />

clinically relevant data sources now provides early indication of<br />

outbreaks 5 . In many countries where public health infrastructure is<br />

rudimentary, deteriorating, or nonexistent, efforts to improve the<br />

ability to conduct electronic disease surveillance include more<br />

robust data collection methods and enhanced analysis<br />

capability. 6,7 However, in these parts of the world, basing timely and<br />

sensitive reporting of public health threats on conventional<br />

surveillance sources remains challenging. Lack of resources and<br />

trained public health professionals poses a substantial<br />

roadblock. 8–10 Furthermore, reporting emerging infectious diseases<br />

has certain constraints, including fear of repercussions on trade<br />

and tourism, delays in clearance through multiple levels of<br />

government, tendency to err on the conservative side, and<br />

inadequately functioning or nonexistent surveillance infrastructure. 11<br />

Even with the recent enactment of international health<br />

regulations in 2005, no guarantee yet exists that broad<br />

compliance will be feasible, given the challenges associated with<br />

reporting mechanisms and multilateral coordination. 12 In many<br />

countries, free or low-cost sources of unstructured information,<br />

including Internet news and online discussion sites (Figure 1),<br />

could provide detailed local and near real-time data on potential<br />

and confirmed disease outbreaks and other public health<br />

events. 9,10,13–18 These event-based informal data sources provide<br />

insight into new and ongoing public health challenges in areas that<br />

have limited or no public health reporting infrastructure but have<br />

the highest risk for emerging diseases 19 . In fact, event-based<br />

informal surveillance now represents a critical source of epidemic<br />

intelligence – almost all major outbreaks investigated by the World<br />

Health Organization (WHO) are first identified through these<br />

informal sources. 9,13<br />

With a goal of improving public health surveillance and,<br />

ultimately, intervention efforts, we (the architects, developers, and<br />

methodologists for the information systems described herein)<br />

reviewed 3 of the primary active systems that process<br />

unstructured (free-text), event-based information on disease<br />

outbreaks: The Global Public Health Intelligence Network (GPHIN),<br />

the HealthMap system, and the EpiSPIDER project (Semantic<br />

Processing and Integration of Distributed Electronic Resources for<br />

Epidemics [and disasters]; www.epispider.net). Our report is the<br />

result of a joint symposium from the American Medical Informatics<br />

Association Annual Conference in 2007. Despite key differences,<br />

all 3 systems face similar technologic challenges, including 1) topic<br />

detection and data acquisition from a high-volume stream of event<br />

reports (not all related to disease outbreaks); 2) data<br />

characterization, categorization, or information extraction; 3)<br />

information formatting and integration with other sources; and 4)<br />

information dissemination to clients or, more broadly, to the public.<br />

Each system tackles these challenges in unique ways, highlighting<br />

the diversity of possible approaches and public health objectives.<br />

Our goal was to draw lessons from these early experiences to<br />

advance overall progress in this recently established field of eventbased<br />

public health surveillance. After summarizing these<br />

systems, we compared them within the context of this new<br />

surveillance framework and outlined goals for future development<br />

and research.<br />

The GPHIN project<br />

Background<br />

GPHIN took early advantage of advancements in communication<br />

technologies to provide coordinated, near realtime, multisource,<br />

and multilingual information for monitoring emerging public health<br />

events. 20,21 In 1997, a prototype GPHIN system was developed in<br />

a partnership between the government of Canada and WHO. The<br />

objective was to determine the feasibility and effectiveness of<br />

using news media sources to continuously gather information<br />

about possible disease outbreaks worldwide and to rapidly alert<br />

international bodies of such events. The sources included<br />

websites, news wires, and local and national newspapers<br />

retrieved through news aggregators in English and French. After<br />

the outbreak of severe acute respiratory syndrome (SARS), a new,<br />

robust, multilingual GPHIN system was developed and was<br />

launched November 17, 2004, at the United Nations.<br />

Innovation and policy: infectious disease surveillance<br />

Data Acquisition<br />

Automated process<br />

The GPHIN software application retrieves relevant articles every 15<br />

minutes (24 hours/day, 7 days/week) from news-feed aggregators<br />

(Al Bawaba [www.albawaba.com] and Factiva [www. factiva.com])<br />

according to established search queries that are updated regularly.<br />

The matching articles are automatically categorized into >1 GPHIN<br />

taxonomy categories, which cover the following topics: animal,<br />

human, or plant diseases; biologics; natural disasters; chemical<br />

incidents; radiologic incidents; and unsafe products. Articles with<br />

a high relevancy score are automatically published on the GPHIN<br />

database. The GPHIN database is also augmented with articles<br />

obtained manually from openaccess web sites. Each day, GPHIN<br />

handles ≈4,000 articles. This number drastically increases when<br />

events with serious public health implications, such as the fi nding<br />

of melamine in various foods worldwide, are reported.<br />

Human analysis process<br />

Although the GPHIN computerized processes are essential for the<br />

management of information about health threats worldwide, the<br />

linguistic, interpretive, and analytical expertise of the GPHIN<br />

analysts makes the system successful. Articles with relevancy<br />

below the “publish” threshold are presented to a GPHIN analyst,<br />

who reviews the article and decides whether to publish it, issue an<br />

alert, or dismiss it. Additionally, the GPHIN analyst team conducts<br />

more in-depth tasks, including linking events in different regions,<br />

identifying trends, and assessing the health risks to populations<br />

around the world.<br />

Data Dissemination<br />

Machine translation<br />

English articles are machine-translated into Arabic, Chinese<br />

(simplifi ed and traditional), Farsi, French, Russian, Portuguese,<br />

and Spanish. Non-English articles are machine-translated into<br />

English. GPHIN has adopted a best-of-breed approach in<br />

selecting engines for machine translation. The lexicons associated<br />

with the engines are constantly being improved to enhance the<br />

quality of the output. As such, the machine-translated outputs are<br />

edited by the appropriate GPHIN analysts. The goal is not to<br />

obtain a perfect translation but to ensure comprehensibility of the<br />

essence of the article.<br />

Information access<br />

Users can view the latest list of published articles or query the<br />

database by using both Boolean and translingual metadata search<br />

capabilities. In addition, notifications about events that might have<br />

serious public health consequences are immediately sent by email<br />

to users in the form of an alert.<br />

Project results<br />

As an initial assessment of data collected during July 1998<br />

through August 2001, WHO retrospectively verified 578<br />

outbreaks, of which 56% were initially picked up and disseminated<br />

by GPHIN. 9 Outbreaks were reported in 132 countries,<br />

demonstrating GPHIN’s capacity to monitor events occurring<br />

worldwide, despite the limitation of predominantly English (with<br />

some French) media sources. One of GPHIN’s earliest<br />

achievements occurred in December 1998, when the system was<br />

the fi rst to provide preliminary information to the public health<br />

community about a new strain of influenza in northern People’s<br />

Republic of China 20 . During the SARS outbreak, declared by WHO<br />

in March 2003, the GPHIN prototype demonstrated its potential as<br />

an early-warning system by detecting and informing the<br />

appropriate authorities (e.g., WHO, Public Health Agency of<br />

Canada) of an unusual respiratory illness outbreak occurring in<br />

Guangdong Province, China, as early as November 27, 2002.<br />

GPHIN was further able to continuously monitor and provide<br />

information about the number of suspected and probable SARS<br />

cases reported worldwide on a near real-time basis. GPHIN’s<br />

information was ≈2-3 days ahead of the official WHO report of<br />

confirmed and probable cases worldwide.<br />

In addition to outbreak reporting, GPHIN has also provided<br />

information that enabled public health officials to track global<br />

effects of the outbreak such as worldwide prevention and control<br />

measures, concerns of the general public, and economic or<br />

political effects. GPHIN is used daily by organizations such as<br />

Innovation and policy: infectious disease surveillance<br />

WHO, the US Centers for Disease Control and Prevention (CDC),<br />

and the UN Food and Agricultural Organization.<br />

The HealthMap Project<br />

Background<br />

Operating since September 2006, HealthMap 22,23 is an Internetbased<br />

system designed to collect and display information about<br />

new outbreaks according to geographic location, time, and<br />

infectious agent 24–26 . HealthMap thus provides a structure to<br />

information flow that would otherwise be overwhelming to the user<br />

or obscure important elements of a disease outbreak.<br />

Healthmap.org receives 1000–10 000 visits/day from around<br />

the world. It is cited as a resource on sites of agencies such as the<br />

United Nations, National Institute of Allergy and Infectious<br />

Diseases, US Food and Drug Administration, and US Department<br />

of Agriculture. It has also been featured in mainstream media<br />

publications, such as Wired News and Scientific American,<br />

indicating the broad utility of such a system that extends beyond<br />

public health practice. 24,26 On the basis of usage tracking of<br />

HealthMap’s Internet site, we can infer that its most avid users<br />

tend to come from government-related domains, including WHO,<br />

CDC, European Centre for Disease Prevention and Control, and<br />

other national, state, and local bodies worldwide. Although the<br />

question of whether this information has been used to initiate<br />

action will be part of an in-depth evaluation, we know from<br />

informal communications that organizations (ranging from local<br />

health departments to such national organizations as the US<br />

Department of Health and Human Services and the US<br />

Department of Defense) are leveraging the HealthMap data stream<br />

for day-to-day surveillance activities. For instance, CDC’s<br />

BioPHusion Program incorporates information from multiple data<br />

sources, including media reports, surveillance data, and informal<br />

reports of disease events and disseminates it to public health<br />

leaders to enhance CDC’s awareness of domestic and global<br />

health events. 27<br />

Data acquisition<br />

The system integrates outbreak data from multiple electronic<br />

sources, including online news wires (e.g., Google News), Really<br />

Simple Syndication (RSS) feeds, expertcurated accounts (e.g.,<br />

ProMED-mail, a global electronic mailing list that receives and<br />

summarizes reports on disease outbreaks) 18 , multinational<br />

surveillance reports (e.g., Eurosurveillance), and validated offi cial<br />

alerts (e.g., from WHO). Through this multistream approach,<br />

HealthMap casts a unifi ed and comprehensive view of global<br />

infectious disease outbreaks in space and time. <strong>Full</strong>y automated,<br />

the system acquires data every hour and uses text mining to<br />

characterize the data to determine the disease category and<br />

location of the outbreak. Alerts, defined as information on a<br />

previously unidentified outbreak, are geocoded to the country<br />

scale with province-, state-, or city-level resolution for select<br />

countries. Surveillance is conducted in several languages,<br />

including English, Spanish, Russian, Chinese, and French. The<br />

system is currently being ported to other languages, such as<br />

Portuguese and Arabic.<br />

Data dissemination<br />

After being collected, the data are aggregated by source, disease,<br />

and geographic location and then overlaid on an interactive map<br />

for user-friendly access to the original report. HealthMap also<br />

addresses the computational challenges of integrating multiple<br />

sources of unstructured information by generating meta-alerts,<br />

color coded on the basis of the data source’s reliability and report<br />

volume. Although information relating to infectious disease<br />

outbreaks is collected, not all information has relevance to every<br />

user. The system designers are especially concerned with limiting<br />

information overload and providing focused news of immediate<br />

interest. Thus, after a first categorization step into locations and<br />

diseases, a second round of category tags is applied to the<br />

articles to improve filtering. The primary tags include 1) breaking<br />

news (e.g., a newly discovered outbreak); 2) warning (initial<br />

concerns of disease emergence, e.g., in a natural disaster area; 3)<br />

follow-up (reference to a past outbreak); 4) background/context<br />

(information on disease context, e.g., preparedness planning); and<br />

5) not disease-related (information not relating to any disease 2–5 are<br />

filtered from display]). Duplicate reports are also removed by<br />

calculating a similarity score based on text and category matching.<br />

Finally, in addition to providing mapped content, each alert is<br />

linked to a related information window with details on reports of<br />

similar content as well as recent reports concerning either the<br />

same disease or location and links for further research (e.g., WHO,<br />

CDC, and PubMED).<br />

Project results<br />

HealthMap processes an average of 133.5 disease alerts/day<br />

(95% confidence interval [CI] 124.1–142.8); ≈50% are categorized<br />

as breaking news (65.3 reports/day). Looking 30 days back<br />

(default display), the system displays >800 breaking news alerts<br />

for any given day. From October 2006 through November 20,<br />

2007, HealthMap had processed >35,749 alerts across 171<br />

disease categories and 202 countries or semiautonomous or<br />

overseas territories. Most alerts come from news media (92.8%),<br />

followed by ProMED (6.5%) and multinational agencies (0.7%).<br />

The EpiSPIDER Project<br />

Background<br />

The EpiSPIDER project was designed in January 2006 to serve as<br />

a visualization supplement to the ProMED-mail reports. Through<br />

use of publicly available software, EpiSPIDER was able to display<br />

topic intensity of ProMED-mail reports on a map. Additonally,<br />

EpiSPIDER automatically converted the topic and location<br />

information of the reports into RSS feeds. Usage tracking showed,<br />

initially, that the RSS feeds were more popular than the maps.<br />

Transforming reports to a semantic online format (W3C Semantic<br />

Web) makes it possible to combine emerging infectious disease<br />

content with similarly transformed information from other Internet<br />

sites such as the Global Disaster Alert Coordinating System<br />

(GDACS) website (www.gdacs.org). The broad effects of disasters<br />

often increase illness and death from communicable diseases,<br />

particularly where resources for healthcare infrastructure have<br />

been lacking 28,29 . By merging these 2 online media sources<br />

(ProMED-mail and GDACS), EpiSPIDER demonstrates how<br />

distributed, event-based, unstructured media sources can be<br />

integrated to complement situational awareness for disease<br />

surveillance.<br />

Data acquisition and dissemination<br />

EpiSPIDER connects to news sites and uses natural language<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 49


Innovation and policy: infectious disease surveillance<br />

processing to transform free-text content into structured<br />

information that can be stored in a relational database. For<br />

ProMED reports, the following fields are extracted: date of<br />

publication; list of locations (country, province, or city) mentioned<br />

in the report; and topic. EpiSPIDER parses location names from<br />

these reports and georeferences them using the georeferencing<br />

services of Yahoo Maps (http:// maps.yahoo.com), Google Maps<br />

(http://maps.google.com), and Geonames (www.geonames.org).<br />

Each news report that has location information can be linked to<br />

relevant demographic- and health-specific information (e.g.,<br />

population, per capita gross domestic product, public health<br />

expenditure, and physicians/1,000 population). EpiSPIDER<br />

extracts this information from the Central Intelligence Agency (CIA)<br />

Factbook (www.cia.gov/library/ publications/the-worldfactbook/index.html)<br />

and the United Nations Development Human<br />

Development Report (http://hdr.undp.org/en) Internet sites. This<br />

feature provides different contexts for viewing emerging infectious<br />

disease information. By using askMEDLINE 30 , EpiSPIDER also<br />

provides context-sensitive links to recent and relevant scientific<br />

literature for each ProMED-mail report topic. After EpiSPIDER<br />

extracts the previously described information, it automatically<br />

transforms it to other formats, e.g., RSS, keyhole markup<br />

language(KML; http://earth.google.com/ kml), and JavaScript<br />

object notation (JSON, a human-readable format for representing<br />

simple data structures; www. json.org). Publishing content using<br />

those formats enables the semantic linking of ProMED-mail<br />

content to country information and facilitates EpiSPIDER’s<br />

redistribution of structured data to services that can consume<br />

them. Continuing along this transformation chain, the SIMILE<br />

Exhibit API (http://simile.mit.edu) that consumes JSON-formatted<br />

data fi les enables faceted browsing of information by using scatter<br />

plots, Google Maps, and timelines. Recently, EpiSPIDER began<br />

outsourcing some of its preprocessing and natural language<br />

processing tasks to external service providers such as OpenCalais<br />

(www.opencalais. com) and the Unifi ed Medical Language<br />

System (UMLS) web service for concept annotation. This action<br />

has enabled the screening of noncurated news sources as well.<br />

Project results<br />

Built on open-source software components, EpiSPIDER has been<br />

operational since January 2006. In response to feedback from<br />

users, additional custom data feeds have been incorporated, both<br />

topic oriented (by disease) and format specific (KML, RSS,<br />

GeoRSS), as has semantic annotation using UMLS concept<br />

codes. For example, the EpiSPIDER KML module was developed<br />

to enable the US Directorate for National Intelligence to distribute<br />

avian infl uenza event-based reports in Google Earth KML format<br />

to consumers worldwide and also to enable an integrated view of<br />

ProMED and World Animal Health Information<br />

Database reports<br />

EpiSPIDER is used by persons in North America, Europe,<br />

Australia, and Asia, and it receives 50–90 visits/hour, originating<br />

from 150–200 sites and representing 30–50 countries worldwide.<br />

EpiSPIDER has recorded daily visits from the US Department of<br />

Agriculture, US Department of Homeland Security, US Directorate<br />

for National Intelligence, US CDC, UK Health Protection Agency,<br />

and several universities and health research organizations. In the<br />

latter half of 2008, daily access to graphs and exhibits surpassed<br />

access to data feeds. EpiSPIDER’s semantically linked data were<br />

also used for validating syndromic surveillance information in<br />

OpenRODS (http://openrods. sourceforge.net) and populating<br />

disease detection portals, like www.intelink.gov and the Research<br />

Triangle Institute (Research Triangle Park, NC, USA).<br />

Discussion<br />

Despite their similarities, the 3 described event-based public<br />

health surveillance systems are highly complementary; they<br />

monitor different data types, rely on varying levels of automation<br />

and human analysis, and distribute distinct information. GPHIN,<br />

being the longest in use, is probably the most mature in terms of<br />

information extraction. In contrast, HealthMap and EpiSPIDER,<br />

being comparatively recent programs, focus on providing extra<br />

structure and automation to the information extracted. Their<br />

differences and similarities, summarized in the Table, can be<br />

analyzed according to multiple characteristics: What data sources<br />

do they consider? How do they extract information from those<br />

sources? And in what format is the information redistributed and<br />

how?<br />

For completeness, the broadest range of sources is critical.<br />

GPHIN’s data comes from Factiva and Al Bawaba, which are<br />

subscription-only news aggregators. Their strategy is to rely on<br />

companies that sell the service of collecting event information from<br />

every pertinent news stream.<br />

In contrast, HealthMap’s strategy is to rely on open-access<br />

news aggregators (e.g., GoogleNews and Moreover) and curated<br />

sources (e.g., ProMED and EuroSurveillance). EpiSPIDER, until<br />

recently, has concentrated on curated sources only (e.g., ProMED,<br />

GDACS, and CIA Factbook). This distinction between free and<br />

paid sources raises the question of whether the systems have<br />

access to the same event information.<br />

After the data sources have been chosen, the next step is to<br />

extract useful information among the incoming reports. First, at the<br />

level of the report stream, the system must fi lter out reports that<br />

are not disease related and categorize the remaining (diseaserelated)<br />

reports into predefi ned sets. Then, at a second level of<br />

triage, the information within each retrieved alert (e.g., an event’s<br />

location or reported disease) is assessed. GPHIN does this data<br />

characterization through automatic processing and human<br />

analysis, whereas HealthMap and EpiSPIDER rely mainly on<br />

automated techniques (although a person performs a daily scan of<br />

all HealthMap alerts and a sample of EpiSpider alerts).<br />

After a report in the data stream is determined to be relevant, it<br />

is processed for dissemination. GPHIN automatically translates<br />

the reports into different languages and grants its clients access to<br />

the database through a custom search engine. GPHIN also<br />

decides which reports should be raised to the status of alerts and<br />

sent to its clients by email. HealthMap provides a geographic and<br />

temporal panorama of ongoing epidemics through an openaccess<br />

user interface. It automatically filters out the reports that do<br />

not correspond to breaking alerts. The remaining alerts are<br />

prepared for display (time codes and geocodes as well as disease<br />

category and data source) to allow faceted browsing and are<br />

linked to other information sources (e.g., the Wikipedia definition of<br />

the disease). These data are also provided as daily email digests<br />

to users interested in specific diseases and locations. Although<br />

GPHIN and HealthMap provide their own user interface,<br />

EpiSPIDER explores conventional formats for reports, adding<br />

50 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and policy: infectious disease surveillance<br />

time-coding, geocoding, and country metadata for automatic<br />

integration with other information sources and versatile browsing<br />

by using existing open-source software. These reports are<br />

displayed under the name of Web Exhibits and include, for<br />

example, a mapping and a timeline view of the reports and a<br />

scatter plot of the alerts with respect to the originating country’s<br />

human development index and gross domestic product per<br />

capita.<br />

A division arises between the HealthMap and EpiSPIDER<br />

strategies and the GPHIN strategy regarding the level of access<br />

granted to users. This division is due in part to the access policies<br />

of the data sources used by the systems, as discussed previously.<br />

A discrepancy also exists in the amount of human expertise, and<br />

thus in the cost, required by the systems. These differences also<br />

raise the question of whether information from one system is more<br />

reliable than that of the others. Undertaking an evaluation of the<br />

systems in parallel is a critical next step. Also, all 3 systems are<br />

inherently prone to noise because most of the data sources they<br />

use or plan to use (Figure 1) for surveillance are not verified by<br />

public health professionals, so even if the system is supervised by<br />

a human analyst, it might still generate false alerts. False alerts<br />

need to be mitigated because they might have substantial undue<br />

economic and social consequences. Eventbased disease<br />

surveillance may also benefit from algorithms linked by ontology<br />

(formal representation of a set of concepts within a domain and<br />

the relationships between those concepts) detecting precursors of<br />

disease events. Measurement and handling of input data’s<br />

reliability is a critical research direction.<br />

Future development should focus on linking these systems<br />

more closely to public health practitioners in the field and<br />

establishing collaborative networks for alert verification and<br />

dissemination. Such development would ensure that event-based<br />

monitoring further establishes itself as an invaluable public health<br />

resource that provides critical context and an alternative to more<br />

traditional indicator-based outbreak reporting. ❏<br />

Innovation and clinical specialities: burns<br />

Burn management<br />

ARTICLE BY M DAVEY AND B AYENI (PICTURED)<br />

McMaster University, Hamilton, Ontario, Canada<br />

Y YING AND MJ DUNCAN<br />

Department of Plastic Surgery, Children’s <strong>Hospital</strong> of Eastern Ontario, Ottawa, Ontario, Canada<br />

Pepita, 6 years old, was thrown into a fire by another child two years earlier and sustained an 8% burn of her<br />

lower back. The burn was initially thought to be superficial, but, months later, the wound is still open and has<br />

never been grafted. Pepita cannot stand upright because she has flexion contractures of both hips and one<br />

knee. Instead, she has to crawl. Her groin was not burned, and the burn on her knee was only a minor one.<br />

Her contractures are the result of failing to ensure that she used her unburnt and minimally burnt limbs<br />

during the acute stage of her injury. She has now been abandoned by her family 1 .<br />

The devastating effects of burns are long lasting at both an<br />

individual and societal level. These impacts are<br />

compounded in resource-poor settings, where the human<br />

and material resources necessary to deal with this complex public<br />

health problem are lacking. Developing nations are<br />

disproportionately affected – 95% of the 322,000 global firerelated<br />

deaths in 2002 occurred in low to middle-resource<br />

countries. 2 A structured and comprehensive approach to burn<br />

care must be applied to resource-poor settings in order to improve<br />

outcomes.<br />

A combination of improved management and prevention<br />

strategies has resulted in important declines in morbidity and<br />

mortality in the developed world. A recent US study demonstrated<br />

a 50% decline in burn-related mortality and hospital admissions<br />

over a 20 year period. 3 Patients are frequently surviving even the<br />

most devastating burns due to advances in infection control,<br />

antimicrobial and biologic wound coverings, as well as a better<br />

understanding of resuscitation and the systemic effects of burn<br />

physiology and associated lung injury in burn patients. However,<br />

a stark contrast is seen when comparing the burn related mortality<br />

rates in high and low-income countries. For example, the WHO<br />

Global Burden of disease database has reported an over 10 fold<br />

difference between mortality rates in South East Asia and Europe<br />

(11.6 vs 0.7 per 100 000 population respectively). 2<br />

Unfortunately, without adequate resources in first-aid, acute<br />

surgical management and rehabilitation facilities, patients that do<br />

survive their burn injuries in developing countries often have poor,<br />

disfiguring and disabling long term outcomes. A Ghanaian study<br />

found that 18 % of childhood burns patients had suffered a<br />

physical impairment or disability. 4<br />

As surgeons working in or supporting those who work in<br />

resource-poor countries, it is imperative that we understand the<br />

region-specific risk factors associated with burns, support<br />

preventative measures and provide rapid and appropriate<br />

resuscitation, surgical treatment and rehabilitation.<br />

Etiology and epidemiology<br />

In order to understand and overcome the challenges in the<br />

management and prevention of burns in low-income countries, a<br />

close look at the epidemiology and causal factors involved is<br />

required. It is also necessary to understand the local economic<br />

constraints and the available healthcare infrastructure.<br />

There exist numerous hospital or clinic-based studies describing<br />

epidemiological characteristics of their burn population. Forjuoh<br />

has published a review of 117 articles from 34 low and middleincome<br />

countries. 5 The majority of these studies dealt with the<br />

pediatric population, with the highest incidence of burns occurring<br />

in infants and toddlers (ages 0-4 years) who are dependant on<br />

others for their care. In a study from Angola which looked at all age<br />

groups, the pediatric population accounted for as much as one<br />

third of all burn victims. 6 A comprehensive population-based study<br />

in Ghana identified and calculated the strength of specific risk<br />

factors found in childhood burns; the presence of a pre-existing<br />

impairment such as epilepsy was associated with 6.7 greater odds<br />

of a burn, a finding supported by many other studies. 7 Other risk<br />

factors identified in case-control studies include history of a burn<br />

or burn-death in a sibling, low income, illiteracy, poor living<br />

conditions (overcrowding, lack of water supply) and careless<br />

7, 8, 9, 10<br />

practices (cooking equipment within reach of children). All<br />

these reflect the importance of identifying and developing<br />

prevention strategies that reach marginalized populations.<br />

In many countries in Africa and Asia, young women are also at<br />

particular risk. A reversal of gender distribution is seen compared<br />

to most other injury mechanisms. Women in East Asia account for<br />

26% of the burn deaths worldwide, the highest burn mortality<br />

rates of any population (16.9 per 100 000 population per year) 5, 11 .<br />

This risk is attributed to the domestic role of women cooking in the<br />

home, using unsafe ground-level stoves oil-lanterns or open-fires<br />

and frequently wearing highly flammable (yet inexpensive)<br />

synthetic, loose clothing 12 . Some authors have found that violence<br />

against women is a frequent underlying causal factor in fatal burns,<br />

often billed as suicide in newlywed young women. 13<br />

Most burns occur in the home, commonly in the cooking area,<br />

accounting for the high proportion of scald burns, followed by<br />

flame burns. Combined, they account for over 80% of all burns<br />

seen in low-income countries 4 . Electrical burns are also frequently<br />

seen in low-income areas where building codes may be less<br />

stringent and homes may be built near high tension wires.<br />

Although most studies report higher burn rates in urban settings,<br />

this could be due to a publication bias, with few district hospitals<br />

having the means to carry out and publish results. 14 Given the lack<br />

of first-aid resources and longer distances to travel to medical care<br />

in rural settings, it is not surprising that outcomes are worse in<br />

these locations. This is intuitively understood and is illustrated in a<br />

South African study showing that the average pre-hospital delay<br />

was 42 hrs in rural South Africa, with high rates of wound infection<br />

(22%), contractures (6%) and prolonged length of stay 15 .<br />

Prevention<br />

At a population health level, the true magnitude of the problem is<br />

not well defined with few standardized comprehensive statistical<br />

collection systems in many low-income countries. Some authors<br />

suggest that the global estimated death rate is a gross<br />

underestimation 14 . It is widely accepted that the social and<br />

economic costs of burn injuries to low-income populations are<br />

great and efforts to develop, evaluate, and implement prevention<br />

strategies specific to the local cultural and economic settings are<br />

urgently needed. Successful examples have been shown to work<br />

in developed countries such as Norway, where with a communitybased<br />

prevention program, the rate of burn-related hospital<br />

admissions was reduced by 52%. 5<br />

With over 2 billion people worldwide preparing meals using<br />

rudimentary traditional stoves or open fires 5 , much interest has<br />

been directed toward developing safer domestic appliances and<br />

energy sources. 14 An example of such a strategy is the inexpensive<br />

redesigned flat kerosene lamp, designed by burn surgeon Dr.<br />

Wijaya Godakumbura of Sri Lanka’s Safe Bottle Lamp Project. 16<br />

Although outcome studies have not formally been performed, with<br />

over 600 000 lamps distributed and accompanying community<br />

based education addressing basic fire-safety, this project is<br />

anticipated to have a major impact on the incidence of lamprelated<br />

accidents.<br />

Recognizing the complexity of the issue and its regional<br />

challenges, the WHO, in collaboration with international partner<br />

agencies, developed in 2008 an evidence-based global strategy<br />

for burn prevention and care. 5<br />

Pathophysiology of burns<br />

There are several processes involved in the local tissue responses<br />

after a burn. An increase in vascular permeability leads to the loss<br />

of water, electrolytes, proteins and heat. 11 The complement and<br />

coagulation cascades are activated and this results in thrombosis<br />

and the release of histamine and bradykinin. These mediators<br />

cause an increase in capillary leak and interstitial edema in distant<br />

organs and soft tissue. In addition, the activation of the<br />

inflammatory cascade can lead to immune dysfunction. All of<br />

these responses increase the patient’s susceptibility to sepsis and<br />

multiple organ failure. 17 These systemic responses are significant<br />

once a burn exceeds 20 percent of the patient’s body surface.<br />

Hypovolemia, immunosuppression, bacterial translocation from<br />

the gut, and Acute Respiratory Distress Syndrome (ARDS) can<br />

ensue. 11<br />

Initial management<br />

Primary survey<br />

The rapid implementation of the ABCs of trauma management<br />

(airway, breathing, circulation) also applies to burns. The initial<br />

physical examination of the burn victim should focus on assessing<br />

the airway and the patient’s hemodynamic status, as well as<br />

estimating the size and depth of the burn. Airway edema can<br />

result in airway obstruction and death. One hundred percent<br />

oxygen should be administered from the outset. If there are any<br />

concerns about the adequacy of the airway, prompt endotracheal<br />

intubation is mandated. 18 In addition, signs of inhalational injuries<br />

should be quickly recognized.<br />

If there are concerns of cervical spine injuries, nasotracheal<br />

intubation can be performed because it has the advantages of<br />

decreased cervical spine manipulation and the tube can be easily<br />

secured by suturing it to the nasal septum. The disadvantage of<br />

nasotracheal tubes is that they tend to be of smaller caliber, which<br />

are not as good for suctioning, and may increase the risk of<br />

sinusitis. In difficult cases, fiber-optic bronchoscopy (if available)<br />

can prove to be an invaluable tool in securing the airway. Vocal<br />

cords, directly injured from smoke, may be resistant to usual<br />

topical anesthesia and care must be exercised to avoid<br />

laryngospasm. Consideration should be given to securing the<br />

tube to the teeth with wires (or heavy sutures), rather than risking<br />

further damage to burned facial skin with tie-tapes.<br />

Once the airway has been addressed, the next step is to place<br />

two large-bore (at least 14 gauge) peripheral intravenous catheters<br />

through non-burned viable tissue. If necessary, these catheters<br />

can be placed through burned skin because the eschar is still<br />

sterile in the acute phase and more importantly, death can result<br />

from delays in fluid resuscitation. A Foley catheter should be<br />

placed to monitor urine output because this is the most<br />

straightforward and reliable indicator of intravascular volume<br />

status in the majority of these patients. Associated life-threatening<br />

injuries such as cardiac tamponade, pneumothorax, hemothorax,<br />

and flail chest must be identified and treated quickly 18 Tetanus<br />

toxoid should also be administered routinely to all burn patients,<br />

depending on immune status.<br />

Assessment of injury<br />

Quantifying the extent (Figures 1 & 2) of the burn is crucial in<br />

determining subsequent management. Burns are dynamic injuries,<br />

and damage to the skin can continue for 24 to 48 hours after the<br />

initial injury due to edema, coagulation of small vessels, pressure,<br />

desiccation, and infection. Thus daily evaluation is of paramount<br />

importance in reassessing burn depth and success of excision 17 .<br />

Superficial burns (1st degree) are generally red, painful, and<br />

involve the most superficial aspect of the skin; as such, they are<br />

not included in the calculation of total body surface area (TBSA).<br />

These blanch to the touch 19 and have an intact epidermal barrier.<br />

Examples include sunburn or a minor scald from a kitchen<br />

accident. These burns will heal spontaneously, will not require<br />

operative treatment, and will not result in scarring. Treatment is<br />

aimed at comfort with the use of soothing topical salves with or<br />

without aloe and oral non-steroidal anti-inflammatory agents.<br />

Surgery is not required for these patients. 20<br />

Partial-thickness (2nd<br />

degree) burns involve<br />

the dermis and<br />

the epidermis. Partialthickness<br />

injuries<br />

classified into two types:<br />

superficial and deep. All<br />

second-degree injuries<br />

involve some amount of<br />

dermal damage, and<br />

the division is based on<br />

the depth of injury into<br />

this structure.<br />

Superficial dermal<br />

burns are erythematous,<br />

painful, may blanch to<br />

touch, and often blister.<br />

Examples include<br />

Figure 1: Burn Depth Burns are usually<br />

classified into superficial, superficial<br />

partial thickness, deep partial thickness<br />

Figure 3: Lund and Browder chart 11<br />

and full thickness. Here we have given<br />

then letters A, B, C, D and E 1<br />

Figure 2: Adult compared to<br />

child burn surface areas<br />

scald injuries from overheated<br />

bathtub water and flash flame<br />

burns from open carburetors.<br />

These wounds will spontaneously<br />

re-epithelialize from retained<br />

epidermal structures in the rete<br />

ridges, hair follicles, and sweat<br />

glands in 7–14 days. The injury<br />

will cause some slight skin<br />

discoloration.<br />

Deep dermal burns into the<br />

reticular dermis will appear more<br />

pale and mottled, will not blanch to touch, but will remain painful to<br />

pinprick. These burns will usually heal in 14–28 days by reepithelialization<br />

from hair follicles and sweat gland keratinocytes,<br />

often with severe scarring. Some of these will require surgical<br />

treatment 20 .<br />

A full-thickness (3rd degree) burn generally is identified by a dry<br />

and leathery appearance, although a plastic-like texture and a<br />

hemorrhagic or purpuric pattern may also be seen. Classically, fullthickness<br />

burn wounds have been described as insensate,<br />

although there is often mixed distribution patterns which make<br />

sensation determination less reliable as a defining characteristic. 19<br />

Deep dermal and full-thickness burns require excision and<br />

grafting with autograft skin to heal the wounds in a timely fashion 19 ,<br />

thus minimizing morbidity from protein loss, sepsis, and<br />

contracture. Since all the elements of the epidermis have been<br />

obliterated in full-thickness wounds, healing can occur only<br />

through wound contraction and/or spreading epithelialization from<br />

the wound edges. In a sizable wound, this process will take weeks<br />

to months to years to complete. 21<br />

Fourth-degree burns involve other organs beneath the skin,<br />

such as fat, muscle, bone, and the brain.<br />

In adults, the rule of nines can be used to quickly estimate the<br />

size of a burn. The anterior and posterior trunk is each l8%, each<br />

of the lower extremities is 18%, each upper extremity is 9%, and<br />

the head is 9%. This is depicted clearly in Figure 2. Unfortunately,<br />

the rule of nines is somewhat inaccurate in children and may<br />

overestimate burn size because the head accounts for a greater<br />

portion of the body surface area (BSA). In a 2-year-old child, this is<br />

19% of the TBSA Diagrams such as the Lund and Browder charts<br />

(Figure 3) are more accurate and should be used for calculating the<br />

burn size in children. 18 In small burns, the surface of the patient’s<br />

hand can be used to estimate the extent of the burn; it represents<br />

approximately 1% of the TBSA (from fingertips to wrist).<br />

Patient selection<br />

Patient selection is the key to improving the outcomes of burn<br />

injury within the resource constraints of a given environment. The<br />

mortality of a given size of burn injury increases in infants and the<br />

elderly. It is difficult to cite what size of burn constitutes a lethal<br />

injury as mortality varies so much around the world, but local<br />

experience will suggest what magnitude of injury is likely to be<br />

survivable given the treatments available. For patients with clearly<br />

lethal burn/inhalation injury it is humane to withhold fluid<br />

resuscitation and airway intervention and provide palliation with<br />

dressings and generous amounts of intravenous morphine.<br />

Depending on circumstances it may be prudent to ask a<br />

colleague to examine the patient and note their concurrence with<br />

the lethality of the prognosis. Patients with severe, but not clearly<br />

lethal burn injuries pose a difficult problem: they can consume an<br />

inordinate amount of scarce hospital resources (ICU days, total<br />

length of stay, dressing supplies, nursing and operating room<br />

time), and still die or have dreadful outcomes. Consultation and<br />

possible referral to a burn centre is helpful. Treatment with pain<br />

control, dressings, prevention of infection, nutritional support,<br />

good splinting and early mobilization of affected joints, and careful<br />

selection of patients for surgical intervention is a sound<br />

policy. Small but potentially disabling burns, especially in children,<br />

should be the main focus of surgical attention. It is in this group<br />

of patients that early surgery, meticulous graft care, splinting,<br />

pressure garments and aggressive physiotherapy will produce the<br />

most gratifying (and cost effective) outcomes.<br />

Fluid resuscitation<br />

The most commonly used formula for adults, for fluid resuscitation<br />

after a burn, is the Parkland formula. To calculate daily fluid<br />

requirements, a crystalloid solution at the rate of 4 mL/kg/%TBSA<br />

burn is given intravenously. The first half of the calculated amount<br />

of fluid is administered within the first 8 hours after the burn, and<br />

the remaining is given over the next 16 hours. In the first 24 hours<br />

post-burn, the initial resuscitation fluid is Lactated Ringers, which<br />

is isotonic to plasma.<br />

56 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: burns<br />

In children, maintenance requirements must be added to the<br />

resuscitation formula, and should be provide as a dextrose<br />

containing solution for infants due to the risk of hypoglycemia if<br />

they are not drinking. The addition of maintenance is less<br />

important in adults due to the large volumes and low risk of<br />

hypoglycemia. One formula that accounts for the maintenance<br />

requirements is the Shiners Burns <strong>Hospital</strong> SBH-Galveston<br />

Formula, which calls for initial resuscitation with 5000 mL/m 2 BSA<br />

burn/d + 2000 mL/m2 BSA/d of Lactated Ringers solution. 18 See<br />

http://www.halls.md/body-surface-area/bsa.htm to express BSA<br />

in M2. Again, the first half is administered within the first 8 hours<br />

post-burn, and the remaining is given over the next 16 hours.<br />

Another option to intravenous fluids, in cases of less severe<br />

burns or where intravenous solutions are at a premium, includes<br />

oral rehydration solution. The WHO describes a method for<br />

preparation of an electrolyte-balanced solution 62 . Although very<br />

time consuming, IV fluids may also be prepared on site at low<br />

cost. 63<br />

It is important to remember that these are only guidelines, and<br />

the infusion volumes must be titrated on a regular basis. Urine<br />

output is the usual indicator of adequate resuscitation. Urine<br />

output in a child should be maintained at 1 mL/kg/h. In an adult,<br />

0.5 mL/kg/h is sufficient (unless myoglobinuria is suspected in<br />

which case it should be over 2 mL/kg/h). It is essential to avoid<br />

over-aggressive resuscitation, which may lead to increased<br />

extravascular hydrostatic pressure and pulmonary edema. This is<br />

especially important in patients who have a cardiac history, as well<br />

as patients with a concomitant inhalation injury, because they will<br />

also have increased pulmonary vascular permeability.<br />

Administration of colloid or hypertonic solutions decreases the<br />

total amount of fluid requirements in the first 24 hours post-injury;<br />

however, no clear advantages in long-term outcomes over isotonic<br />

crystalloid resuscitations have been clinically <strong>document</strong>ed. In<br />

general, crystalloid resuscitation with isotonic Lactated Ringers is<br />

the best option in the acute phase. 18<br />

If a patient is having increased fluid requirements, it should raise<br />

suspicion of concomitant inhalation injury, a delay in resuscitation,<br />

or another associated injury. It must be reiterated that the most<br />

important thing is to begin resuscitation as soon as possible after<br />

the time of injury. Unfortunately, delays in adequate resuscitation<br />

are common and lead to increased fluid requirements because of<br />

additive perfusion-reperfusion injury, which lead to unnecessary<br />

loss of life. 18<br />

Escharotomy<br />

With circumferential full thickness, or deep partial thickness burns,<br />

there must be a high index of suspicion for compartment<br />

syndrome. The decreased skin compliance does not<br />

accommodate the extreme edema from the inflammatory<br />

response. Swelling increases with fluid resuscitation and it is<br />

much better to release a limb with early escharotomies than to<br />

discover too late that compartment syndrome and myonecrosis<br />

have set in. The diagnosis of compartment syndrome in a burned<br />

patient is challenging. Pallor is difficult to determine because the<br />

eschar often is discolored, soot stained and can be pale and<br />

leathery or red and plastic-like to the touch. Most burn wounds are<br />

painful to the touch, unless an area of pure full thickness exists.<br />

Paresthesia and paralysis are late findings of compartment<br />

syndrome and are impossible to address in a patient that may be<br />

paralyzed or sedated.<br />

The absence of a pulse<br />

is similarly too late<br />

of a finding. Delayed<br />

escharotomies can lead<br />

to muscle necrosis<br />

and limb loss. Sufficient<br />

release can usually be<br />

noted as soon as the<br />

dermis is released,<br />

as the wound opens<br />

and subcutaneous<br />

tissue bulges out.<br />

Escharotomies may need<br />

to be done on any limb.<br />

(Figure 4) Escharotomy<br />

may be done with a<br />

scalpel or diathermy<br />

blade. While it is true that Figure 4: Escharotomy lines<br />

full thickness burns are<br />

usually insensate, it is not true that escharotomy can routinely be<br />

performed without some kind of pain control. Ketamine or<br />

fentanyl and versed are safe and effective. The incision should go<br />

through skin but not into fascia or muscle. The mid-medial and<br />

mid-lateral lines of each limb are incised. A small “T” where the<br />

incision meets normal skin will ease constriction at the end of the<br />

incision.<br />

Thoracic escharotomies are also occasionally required for<br />

improving chest-wall compliance and facilitate ventilation. This<br />

may require multiple incisions across the chest, both longitudinally<br />

and transversely to allow full chest expansion. Figure 4 shows<br />

possible thoracic escharotomy lines, but more lines may be<br />

required for very deep constricting burns.<br />

In electrical injury, the final extent of tissue injury can be difficult<br />

to predict. Frequent assessments and surgical debridements are<br />

required often in the face of progressive myonecrosis. With any<br />

high voltage electrical injury, the index of suspicion for a deep<br />

injury should be high. The skin wound is not a reliable indicator of<br />

the underlying damage. These injuries will require a fasciotomy,<br />

with release of all muscle compartments to minimize muscle<br />

damage. Patients should also be monitored for myoglobinuria<br />

which will require treatment with increasing urine output,<br />

alkalinization of the urine, and sometimes with very cautious use of<br />

diuretics. Untreated myoglobinuria can lead to deposition in the<br />

glomerular tubules and renal failure.<br />

Inhalation injury<br />

Inhalation injuries are associated with severe burns and poor<br />

outcomes. A retrospective review in Cape Town, South Africa<br />

found that inhalation injury was present in 63% of severe burn<br />

patients (>30% TBSA), which resulted in a mortality rate of 76%. 21<br />

However, it is believed that inhalation injuries are more frequently<br />

seen in high income countries due to the high prevalence of house<br />

burns, where victims are confined to enclosed spaces. Alcohol<br />

and smoking account for over half the deaths in developing<br />

countries, so prolonged exposure to smoke may occur as a result<br />

of intoxication. The prevalence of inhalational injury in low to<br />

middle income countries is unknown, but suspected to be lower.<br />

The reason for differences in prevalence is unclear, whether due to<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 57


Innovation and clinical specialities: burns<br />

under diagnosis 20 or a true difference given that the vast majority<br />

of burns occur outdoors. Researchers have found prevalence<br />

rates of inhalational injury in South Africa of 2.2 % of pediatric burn<br />

patients 19 and 14.5% of adult burn patients. 21<br />

Successful management of inhalation injuries relies on early<br />

suspicion and resuscitation, as well as minimizing post-injury<br />

complications such as bronchopneumonia and acute respiratory<br />

distress syndrome (ARDS).<br />

In the early resuscitation phase (< 36hrs), it is key to suspect<br />

inhalation injury, consider early intubation and empirically<br />

oxygenate these patients. Patients who have had prolonged<br />

exposure to smoke (ie. trapped indoors), loss of consciousness,<br />

flash burns with singed facial hair, carbonaceous sputum,<br />

hoarseness should all be closely observed for impending airway<br />

obstruction. Suspicion should also be high in patient with facial<br />

scald injuries, where airway compromise is often misdiagnosed.<br />

Scald burns can be associated with direct thermal injury to the<br />

upper airway from ingestion of hot liquids or steam inhalation. 19<br />

Intubation with a large endotracheal tube (to enable suctioning)<br />

should be done in patients with stridor, increased work to<br />

breathing, respiratory distress, hypoxia, hypercapnea, deep burns<br />

to the face or edema/erythema of the oropharynx on<br />

laryngoscopic exam. Respiratory distress may not develop for<br />

several hours, and intubation should be performed in the case of<br />

transfer in high risk patients even in absence of stridor as<br />

obstruction may progress quickly as a result of airway<br />

inflammation from injury or edema from resuscitation. 22<br />

Smoke inhalation injury is often associated with significant<br />

carbon monoxide exposure, resulting in carboxyhemoglobinemia.<br />

Carbon monoxide poisonings account for the majority of deaths,<br />

which occur at the scene or early in the pre-hospital phase.<br />

Asphyxia or anoxic brain injury develop quickly; as the oxygencarrying<br />

capacity of the blood is decreased. The clinical<br />

manifestations of carbon monoxide poisoning are non-specific<br />

and can include headache, malaise, confusion, dyspnea, seizures<br />

and loss of consciousness. The diagnosis of carbon monoxide<br />

poisoning may be hard to confirm, given its imprecise<br />

presentation, unavailable carboxyhemoglobin levels, and<br />

misleading O 2 saturation measurement. Conventional pulse<br />

oxymetry monitors are unable to distinguish O 2 saturation from CO<br />

saturation, and therefore the patient may have a falsely normal O 2<br />

saturation reading. Patients may also appear pink/red and wellperfused,<br />

classically described as “cherry red”. PaO 2 should be<br />

confirmed by blood gas if possible. Clinical suspicion is the<br />

mainstay for diagnosis and treatment. Given poor outcomes<br />

associated with neurologic findings or loss of consciousness in the<br />

setting of carbon monoxide poisoning 23 , administration of high flow<br />

oxygen should be used liberally to reverse tissue hypoxia and to<br />

accelerate the displacement of carbon monoxide (as well as<br />

cyanide) from their binding sites. The half-life of<br />

carboxyhemoglobin can be decreased from 240 minutes to 75-80<br />

minutes by using 100% FiO 2 instead of room air (21% FiO 2). 24<br />

In the post-resuscitation phase (2-5 days) many competing<br />

factors can contribute to exacerbate pulmonary insufficiency.<br />

Direct thermal injury or exposure to bronchopulmonary toxins from<br />

smoke exposure can lead to airway edema, inflammatory changes<br />

and activation of systemic inflammatory response, as well as<br />

disruption of the muco-ciliary transport, increased capillary<br />

permeability, mucosal necrosis and sloughing. As a result<br />

subsequent distal airway obstruction, from atelectasis, edema and<br />

inflammatory debris, leads to a high risk of bronchopneumonia;<br />

the most frequent complication seen in a cohort of children with<br />

inhalational injuries in South Africa, seen in 32% of patients 19 .<br />

Other compounding factors include non-cardiogenic pulmonary<br />

edema secondary to aggressive fluid resuscitation in burn<br />

patients, poor lung compliance and chest wall rigidity in the setting<br />

of trunk burns, secondary ventilatory-associated lung injury from<br />

aggressive high tidal volume, ventilator associated pneumonia,<br />

relative immunosuppression and the emergence of multi-drug<br />

resistance. 25<br />

Recent recommendations to minimize respiratory complications<br />

in burn patients have been shown to improve outcomes in high<br />

income countries. 25,26 These include using low tidal volume<br />

ventilation with PEEP (positive end expiratory pressure) to maintain<br />

alveolar patency and minimize baro-trauma, humidified<br />

oxygenation and elevating the head of the bed to improve<br />

pulmonary toilet and judicious use of antibiotics based on<br />

bronchoalveolar lavage cultures. Other interventions and<br />

treatments remain controversial including early tracheostomy 27 ,<br />

adjunct inhalational therapies (heparin or N-acetylcysteine) or<br />

other modes of ventilation. Corticosteroids have been shown to be<br />

harmful in this patient population 28 .<br />

The final inflammatory-inflammation phase of injury (5 days and<br />

beyond) persists until complete lung healing and burn wound<br />

closure, during which time patients remain at risk for infectious<br />

complications.<br />

Most patients do not suffer from long-term respiratory<br />

complications as a result of their lung injury, with evidence of<br />

normal lung function seen in a study at 4 years post-injury 29 .<br />

Rarely, complications such as fibrosis and tracheal stenosis have<br />

been seen and should be managed independently of the causal<br />

etiology.<br />

Wound care<br />

Wound care is a fundamental pillar in the care of the burn patient,<br />

and an area of evolution partially responsible for improved survival<br />

seen since the 1960s. As a result of loss of dermal integrity, the<br />

burn wound loses its protective barrier against invasion by microorganisms<br />

and against evaporative losses. Therefore, until<br />

complete re-epitheliazation occurs, the burn dressing serves a<br />

number of functions: protection against micro-organism invasion,<br />

minimizing metabolic losses, limiting the pain of exposed burn<br />

surfaces, containing messy wound secretions, and hiding the burn<br />

to help prevent adverse psychological responses. 30 Most of the<br />

practices used in modern burn units are based on anecdotal or<br />

uncontrolled clinical observations. However, with the introduction<br />

of topical antimicrobial prophylaxis, occlusive dressing, and<br />

improved sterility as well as a goal of early wound closure, the<br />

incidence of burn wound infections have steadily declinedV.<br />

Burn wound care requires an experienced eye and knowledge<br />

of the dressing options available. Surgeons often lack the time to<br />

examine wounds as often as they should so developing expertise<br />

in the nursing staff is important. If dressings are changed each day<br />

by a nurse experienced in burns many problems will be averted<br />

and if staff understand well the importance of both splinting and<br />

early mobilization to prevent contracture functional results will<br />

improve. The routine inspection of wounds by a knowledgeable<br />

person is at least as important as the selection of the dressing<br />

material itself. This is the advantage of a burn team.<br />

Exposure Method: Leaving a burn open is a poor option but<br />

where dressings are not possible it may be the only option. The<br />

patients is washed daily and kept of clean dry sheets with another<br />

sheet or mosquito net draped over a frame to reduce the pain<br />

from air currents and to reduce contamination from the<br />

environment. Ambient temperature control is important to maintain<br />

normothermia. Exposure is less painful for full-thickness burns<br />

than for partial thickness burns but has little else to recommend it.<br />

Tubbing: Most modern burn units avoid the regular immersion<br />

of patients in water both because they practice early excision and<br />

grafting and because of the high risks developing resistant strains<br />

of bacteria in the tub environment and of patient cross-infection.<br />

That said, tubbing can be helpful to clean the wounds and gently<br />

remove eschar as it separates. When early wound infections<br />

develop suspect the tub! Avoid the routine immersion of infected<br />

patients in filthy bathtubs of cold water on the basis of ignorance<br />

and tradition.<br />

Bland Dressings: These provide a clean, moist wound healing<br />

environment, absorb exudates protect from contamination and<br />

provide comfort at a fraction of the cost of antibiotic dressings.<br />

Where antibiotic dressings are scarce bland dressings are a very<br />

acceptable solution for burns. Expensive topical antibiotic<br />

dressings may be reserved for infected wounds. Paraffin gauze is<br />

widely available and can be manufactured locally. Honey and ghee<br />

dressings were first advocated in Ayurvedic texts two thousand<br />

years ago and remain an excellent choice for bland burn<br />

dressings. Mix two parts honey with one part ghee (clarified butter)<br />

and pour over a stack of gauze dressings in a tray. Cover and<br />

store. Vegetable oil or mineral oil may be substituted for Ghee.<br />

Gauze sheets can be applied directly to the wound in a single layer<br />

and covered with plain dry gauze to absorb exudates, then<br />

wrapped. Dressings should be changed at least ever second day,<br />

or when soiled.<br />

Antimicrobial dressing: There exist numerous topical<br />

antimicrobial agents that are effective in delaying the onset of<br />

invasive wound infections, but none prevent them entirely. This is<br />

why they must be used in conjunction with a goal of early surgical<br />

wound closure when possible. A brief review of the agents most<br />

likely to be available to low and middle income countries will follow.<br />

There are also alternative synthetic wound coverings and newer<br />

silver-ionized agents that can be used; however they are often very<br />

costly and inaccessible in low-income countries. A more detailed<br />

review, as well as instructions for preparation, can be found in<br />

these references. 11,33<br />

Silver sulfadiazine (SSD, Flamazine), is by far the most frequently<br />

used agent, given its broad antimicrobial coverage, painless<br />

application and minimal toxicity. It is better to apply the SSD to<br />

large gauze squares and to apply these to the wound than to<br />

attempt to cover the burn in an even coat of cream before<br />

applying the gauze. A very loose plastic or surgical glove<br />

containing silver sulfadiazine and gently secured with tape around<br />

the wrists is a simple and excellent hand dressing. Splints can be<br />

applied outside the bag and the fingers can easily be mobilized to<br />

Innovation and clinical specialities: burns<br />

reduce swelling and prevent stiffening.<br />

There exist many other less expensive options worthy of<br />

mention. Honey has well established antimicrobial properties, and<br />

has demonstrated effectiveness in limited studies. 34 Tannins, as<br />

found in tea leaves, have also been shown to have antibacterial<br />

properties and may reduce the incidence of hypertrophic<br />

scarring. 64,65 Amniotic membrane, used as a biologic wound<br />

coverage has also been shown to be more effective than<br />

nitrofurazone in decreasing the incidence of wound infection 35 , as<br />

well as being cost-effective in reducing the length of stay and<br />

increasing epithelialization 36 . Obvious caution regarding the risk of<br />

disease transmission with the use of human tissue should be used<br />

and comprehensive donor viral screening performed prior to widespread<br />

adoption of this technique. Another innovative way to<br />

minimize cost yet still provide an occlusive dressing to prevent<br />

dehydration has been demonstrated in India with the use of<br />

Banana leaves. 37 Gore et al have shown an acceptable level of<br />

patient acceptance, in comparison to potato peels. Both options<br />

provide wound protection and healing at a fraction of the cost of<br />

conventional dressings.<br />

If despite vigilance, an invasive wound infection becomes<br />

evident on serial observations, one must consider altering the<br />

current treatment protocol. An invasive wound infection can be<br />

determined by clinical expertise or suggestive by wound cultures<br />

showing >10 5 organism per gram or invasion seen on tissue<br />

biopsy. Invasion of microorganism into viable tissues may lead to<br />

progression of the burn or systemic sepsis. It should be noted that<br />

elevated temperatures per se are not necessarily indicative of<br />

sepsis, but are common secondary to the inflammatory<br />

component of the burn wound process. The same organisms<br />

have been identified in serial wound cultures in both low and<br />

middle income countries, with Staph aureaus, Proteus, Klebsiella,<br />

E.coli and Pseudomonas being the most common. The problem<br />

of drug resistance is not confined to high income countries 38 . A<br />

recent Nigerian study, looking at serial wound cultures, concluded<br />

that systemic prophylactic antibiotics did not reduce invasive<br />

infection, but may in fact select more virulent, resistant strains of<br />

bacteria 39 , a notion which has gained wide spread acceptance.<br />

We should therefore guide our antimicrobial use by evidence of<br />

invasive infection, organism culture and sensitivities when these<br />

are known. Prophylactic antibiotics at the time of initial admission<br />

are not routinely advised.<br />

Medical management<br />

Severe burn wounds are known to induce systemic inflammatory<br />

response syndrome (SIRS) through the release of a series of proinflammatory<br />

endotoxins, exotoxins from infectious sources or<br />

from the wound itself. Although the exact mechanism is not well<br />

understood, it is clear that there is a systemic response which can<br />

lead to progressive infection, immuno-suppression, sepsis and<br />

eventually multi-organ failure. Supportive measures are needed<br />

early in the care of the severely burned patient to minimize the<br />

progression and attenuate the hypermetabolic response to burn<br />

injury.<br />

Nutritional support<br />

Early nutritional support is essential in burn patients, even more so<br />

in low-middle income countries where many patients present<br />

malnourished. Burn patients demonstrate levels of metabolism<br />

that can be as high as 200% normal and that are proportional to<br />

the severity of the burn. The metabolic rate does not return to<br />

normal until wound closure. Supporting this high metabolic rate<br />

with diets rich in carbohydrate and protein without overfeeding<br />

patients can decrease muscle wasting, and poor wound healing<br />

consequences of chronic malnutrition. Early feeding also avoids<br />

mucosal atrophy and bacterial translocation. 40 This is particularly<br />

important for intubated patients, for whom feeding is often not<br />

initiated at presentation, increasing the risk of bacterial sepsis.<br />

Strategies to achieve this goal include tube feeding, which should<br />

begin within 6 hours, weekly monitoring patients’ weights, and the<br />

creation of high protein high-caloric feeds from locally available<br />

produce. The frequency of the feeds should be adjusted to the<br />

severity of the burn (%TBSA) and the patient’s pre-existing<br />

nutritional status. 11<br />

Anemia<br />

Unfortunately the prevalence of underlying disease in burn patients<br />

is common in low to middle income countries and may influence<br />

treatment options. A Liberian study found that 61% of their<br />

patients had underlying medical co-morbidities, including epilepsy,<br />

anemia as a result of malaria, or iron deficiency and malnutrition 41 .<br />

Anemia and malnutrition contribute to infectious complications in<br />

these burn patients; however grafting was possible, albeit<br />

delayed, in this study, with surgery being performed between 5-96<br />

days (average 29.8 days) with reasonable graft take (mean 81%).<br />

There is no question that the benefits of early excision must be<br />

weighted against the risk of blood loss and physiological needs of<br />

these specific patients. However, new understanding of the<br />

potentially infectious complications of blood transfusion is<br />

emerging as a result of large prospective multi-centered ICU<br />

trials 42 . A recent multicentre retrospective cohort study that has<br />

shown an associated 13% rise in infectious complications per unit<br />

of blood transfused and an associated increased mortality rate<br />

even when accounting for burn severity 43 . This study underlined<br />

the importance of further research to establish appropriate<br />

transfusion guidelines. Strategies should be undertaken to<br />

minimize blood loss during surgery. Some techniques for<br />

minimizing blood loss are discussed in the surgical management.<br />

HIV<br />

Another important consideration in many low-income countries is<br />

the burn patient who is HIV positive. Until recently, little was known<br />

regarding clinical outcomes in this specific patient population.<br />

James et al conducted a study in a burn unit in Malawi 44 , showing<br />

a 31% HIV prevalence rate in their adult burn population (34 of 112<br />

patients) and in 3% of the pediatric burn patients (6 of 231 patients<br />

under the age of 15). The researchers found that HIV status was<br />

an independent risk factor for death, mostly from infectious<br />

complications with more marked immunosuppression, as<br />

indicated by a lower mean CD 4 count (383mm 3 vs. 937 mm 3 in<br />

HIV negative patients). They found no differences in bacterial<br />

cultures, need or outcome of skin grafting, transfusion or antibiotic<br />

requirements or length of stay. In a case-controlled study out of<br />

South Africa 45 , no differences in mortality or morbidity was found<br />

when comparing 33 patients with and without HIV, when matched<br />

for age, sex, burn severity and inhalational injury. Two patients with<br />

clinical AIDS died of infectious complications leading the authors<br />

to conclude that HIV positive patients, without the stigmata of<br />

60 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: burns<br />

AIDS should be treated in the same manner with similar outcomes<br />

expected. Further research is needed to understand the effect of<br />

HIV on immunosuppression in its early stages of disease.<br />

Surgical management<br />

After hemodynamic stabilization, a burned patient’s priority of<br />

treatment shifts to ‘burn-wound-management’ 46 . Preoperatively,<br />

several factors can pose a challenge to surgical patient care. In<br />

the developing world, many of the burns present late, already<br />

infected, or the poor general health of the patients makes them<br />

unfit for anesthesia. In addition, blood loss can be significant in<br />

burn wound excision, especially since inflamed and infected<br />

wounds tend to bleed more during tangential excision. Thus, burn<br />

surgery can be dangerous in high risk patients where blood<br />

transfusion facilities are not readily available.<br />

The options for the surgical management of burns includes early<br />

tangential excision and grafting for deep dermal burns and<br />

delayed escharectomy skin grafting for full thickness skin loss 47 .<br />

Tangential excision describes the sequential and layered excisions<br />

of devitalized tissues to a vital bed, generally recognized by<br />

punctuate bleeding. An inadequately excised wound is more likely<br />

to become infected and is unsuitable for graft take, necessitating<br />

further surgery. 19 The use of tumescence (discussed below) is<br />

good for decreasing blood loss from the burn site; however it<br />

makes judgment of adequacy of excision and of hemostasis more<br />

difficult. It can decrease blood loss to a minimal amount. Adequate<br />

debridement must instead be determined by tissue quality, and<br />

not by punctuate bleeding.<br />

The exact timing for wound excision is debatable. It is often<br />

suggested that burn wounds should be excised and grafted if they<br />

are not expected to heal within 21 days of injury. This is especially<br />

true for key functional and esthetic locations such as the hands<br />

and face. 19 The decision to perform extensive excisions in a single<br />

setting versus staged procedures is dependent upon the<br />

hemodynamic stability of the patient, the availability of resources,<br />

and the coordination of all parties involved in the care of the<br />

patient. 19 Conservative treatment of burn wounds, with silver<br />

sulfadiazine, followed by serial excision of the burn wound is<br />

currently the standard of care in many burn centres throughout the<br />

world. Burns are excised in areas of as much as 20% TBSA in one<br />

operative setting, and performing the entire excision of the burn<br />

wound in 10 days post-injury is the goal. All full-thickness burns<br />

can be excised first, so that deep dermal and indeterminate depth<br />

wounds are addressed later, preventing excision of potentially<br />

viable tissue. Early excision and grafting is the treatment of choice<br />

to potentially reduce scar contractures and hypopigmentation 47 .<br />

The disadvantages to serial excision are that the patient needs to<br />

return many times to the operative room, so that episodes of<br />

bacterial translocation, bacteremia, and cardiovascular instability<br />

are repeated. Other disadvantages include exaggerated blood<br />

losses, prolongation of the hypermetabolic response, and<br />

increased risk of infection and sepsis from remaining eschar in<br />

which bacteria proliferate.<br />

Near-total wound excision has been advocated as an alternative<br />

to serial debridement in massive burns. In near-total excision, all<br />

full-thickness and partial-thickness burns are excised within 24<br />

hours of admission, and the excised wounds are covered with<br />

autografts and skin substitutes are used if the burn exceeds the<br />

donor-site supply. Areas of the face are normally not excised in the<br />

first operation. Near-total burn excision has dramatically improved<br />

survival in massive burns 18 . However, it has been postulated that<br />

the surgical trauma of immediate burn wound excision, especially<br />

given the hemodynamic instability of burn patients during the first<br />

72 h after the injury, may aggravate the inflammatory and catabolic<br />

responses, leading to potentially fatal postoperative<br />

complications. 18,47 It should be clear that near-total wound excision<br />

is only meant for massive burns, and allograft/autograft/xenograft<br />

must be available for coverage, or the wounds would only have<br />

been converted to full thickness open wounds.<br />

General surgical principles<br />

The intent of burn wound operations is twofold: to remove<br />

devitalized tissue and restore skin continuity. For this process to<br />

take place and for the skin graft to take, four things are required:<br />

✚ A viable wound bed.<br />

✚ No accumulation of fluid between the graft and the wound<br />

bed.<br />

✚ No shear stresses on the wound.<br />

✚ Avoidance of massive micro-organism proliferation.<br />

Surgical debridement is performed using a Goulian blade for small<br />

areas or those with multiple irregular contours (e.g., hand or knee)<br />

and a Watson or Humby blade for larger areas. Inexpensive<br />

alternatives have been proposed for harvesting and debriding<br />

blades 48 . Burned tissue is excised tangentially and sequentially<br />

until the wound has been excised down to healthy dermis, fat,<br />

muscle, peritenon, or periosteum. The wound may then be<br />

covered with an autograft, allograft, or synthetic skin substitute.<br />

Graft depth should be adjusted in pediatric and geriatric<br />

populations for their thinner reticular dermis layer. If using a<br />

powered dermatome, it should be set at less than 10/1000th<br />

inch. The meshing pattern used for wound closure depends on<br />

burn surface area and donor site availability. Meshing of the skin<br />

graft has several advantages, including expanding the square<br />

centimeters of coverage, allowing for drainage of fluid from under<br />

the graft, and allowing for placement of the graft over contoured<br />

areas, such as the knee or ankle. The disadvantage of the meshed<br />

skin graft includes a permanent weave-like appearance of the<br />

healed scar site, and increased contraction. 17<br />

Many authors have described innovative methods for<br />

performing skin grafting in resource-poor settings 49 . With minimal<br />

financial resources, using readily available modified household or<br />

industrial materials a surgeon is able to sharpen the Humby knife<br />

48, 50<br />

and use a pizza cutter for meshing grafts.<br />

Methods of optimizing hemostasis and minimizing blood losses<br />

include meticulous attention to maintaining the patient’s core body<br />

temperature (operating in a warm environment, isolating surgical<br />

fields, warming intravenous fluids, warming humidified air circuits<br />

for anesthesia), the use of cautery, the application of topical<br />

epinephrine solutions or topical thrombin solutions, injecting dilute<br />

epinephrine tumescent solution below the eschar, and the use of<br />

topical fibrin sealants.<br />

The use of tumescence and tourniquet in burn excision<br />

significantly reduces intraoperative blood loss and facilitates<br />

accurate wound excision. Epinephrine is diluted in saline to a<br />

concentration of 1:500,000 (2mg/l) and large volumes are injected<br />

beneath the wound to be excised. Use a concentration of<br />

1:1,000,000 for children. The edges of the wound are scored with<br />

a scalpel and the burned dead skin is sliced away with a grafting<br />

knife. Tangential excision is continued to the point where the<br />

dermis looks healthy, clean and pearly white, fat appears shiny and<br />

yellow with no haem staining and small visible vessels have<br />

patency and flow. If the fat does not look healthy consider excision<br />

down to the fascia which is possessed of a better blood supply<br />

than the fat. Bleeding vessels are coagulated and the wound is<br />

wrapped in adrenaline saline soaked gauze while natural<br />

haemostasis takes place. Attention is the turned to the donor site<br />

and a template of gauze from the excised wound is used to<br />

measure the area of skin to be harvested. Adrenaline saline is<br />

injected beneath the donor site till the skin is taught and blanched<br />

then it is harvested with the humby knife or power dermatome.<br />

The donor wound is wrapped in adrenaline saline gauze while<br />

attention returns to the burn site. When hemostasis is satisfactory<br />

the grafts are applied and secured in place. Local anesthetic can<br />

also be added for small wounds, with 20ml of 1% xylocaine added<br />

to 1 L of solution. The addition of local anesthetic to the solution<br />

can decrease pain, reducing anesthetic agents and narcotics<br />

during surgery but the toxicity of xylocaine exceeds that of the<br />

adrenaline. A number of recent papers have addressed the safety<br />

of high dose adrenaline tumescence during burn excision and are<br />

cited here to placate anesthetic concerns. Atropine and ketamine<br />

are poor choices for tumescent burn excision as the patient will be<br />

tachycardic and hypertensive even before adrenaline infiltration is<br />

begun. Excision of burns from the extremities under tourniquet<br />

control can minimize bleeding significantly<br />

If possible, donor sites should be chosen that are inconspicuous<br />

and will have a good color match for the wound bed. Donor sites<br />

may develop hypertrophic scars and should not cross joints.<br />

Potential donor sites include the upper thigh or the buttock, which<br />

remain hidden with normal clothing and the back, which heals well<br />

but is technically difficult to harvest with a hand held grafting knife.<br />

Selection of the donor site should also consider the color match of<br />

the wounded area, which is most significant on the head and<br />

neck. A number of types of donor site dressings are available. The<br />

first type is a fine-mesh cotton gauze that may or may not be<br />

impregnated. Dressings of this type include Scarlet Red and<br />

Xeroform, which have the advantage of low cost and familiarity.<br />

These may need to be reinforced with more gauze initially that can<br />

be removed in 24-48 hours, and the inner layer left intact. The<br />

adherent gauze will start lifting in 1-2 weeks as the wound reepithelializes.<br />

The edges can be trimmed off as they<br />

spontaneously lift. An occlusive dressing such as<br />

OpSite/tegaderm can also be used, but may require a few holes<br />

to drain seromas. 47<br />

Loss of dermis leads to significant scarring and wound<br />

contracture. There are a number of dermis substitutes that can be<br />

used such as Integra and AlloDerm. These products allow the use<br />

of a very thin partial thickness skin graft on top of the dermis.<br />

These products require a very clean wound bed, and meticulous<br />

cleanliness post-operatively to prevent infection. These two<br />

options are very expensive, though, and are not mainstays of the<br />

armamentarium of burn surgeons in the developing world.<br />

Grafts must be held in place by sutures or staples. Some form<br />

of dressing is required to hold grafts in place. In more mobile<br />

locations, a bolster dressing may be placed on top of the graft. An<br />

inner layer that can maintain moisture (petroleum jelly or mineral oil<br />

product) should be placed before gauze. Grafts over joints will<br />

require casting/splinting for the time period for grafts to take,<br />

usually 10-14 days. Dressings are left intact during the time<br />

period.<br />

Specific anatomic considerations<br />

Particular anatomical regions require specific treatments. The<br />

head and neck region is well vascularized and this is protective<br />

against invasive infection. Excision and grafting of the face is<br />

ideally done in full aesthetic units (Figure 5). Early excision of<br />

eschar is not recommended in order to preserve any dermal and<br />

epidermal structures that may survive. Once the eschar separates<br />

in 10–14 days, the underlying wound can be grafted. The color of<br />

the skin in this area is relatively specific; therefore, autograft skin<br />

should be obtained from donor sites above the clavicles. The<br />

scalp is an excellent donor site for<br />

the face 21 .<br />

With regards to the breasts,<br />

keratinocytes are often found<br />

deep beneath the skin. These will<br />

proliferate and facilitate wound<br />

closure if left in place. The<br />

coloration of the areola is also<br />

very specific so the nipple/areolar<br />

complex should not be excised.<br />

The buttocks and perineum are<br />

in a very difficult position for skin<br />

grafts to take, since the dressings<br />

applied are often soiled from<br />

Figure 5: Anantomic subunits<br />

of the face<br />

excrement, and cleaning, often shearing the grafts. It may be<br />

necessary to leave the patient in the prone position at later<br />

operations after application of grafts to this area while they adhere.<br />

In extreme cases, a temporary defunctioning colostomy may be<br />

considered until the burn wounds in the perineum are closed.<br />

The penis and scrotum have an excellent blood supply, so they<br />

will usually heal in a timely fashion. The skin in this region occupies<br />

a highly important function, so, in general, excision is avoided. In<br />

the case of a small burn to the shaft of the penis, excision and<br />

primary closure akin to a circumcision can suffice. The scrotum is<br />

also a very good donor site because it heals well, is relatively<br />

hidden, and can be vastly expanded to provide a surprising<br />

amount of donor skin.<br />

The hands are very important in terms of function and cosmesis.<br />

Most burns of the hand are limited to the dorsal surface as the<br />

hand is clenched during injury. Unfortunately, sometimes the digits<br />

sustain a second injury associated with diminished perfusion<br />

during resuscitation. Escharotomies along the axial lines may<br />

salvage digits during resuscitation. Grafts placed on the hands<br />

should either be unmeshed or meshed tightly at a 1:1 ratio to<br />

improve cosmesis. Burns through to the extensor tendons can<br />

result in boutonniere deformities even with complete wound<br />

closure due to sliding of tendons medial and lateral around the<br />

proximal interphalangeal joint. Extension contractures at the<br />

metacarpophalangeal joint are also common because the burn<br />

and subsequent scarring are limited to the dorsal surface. For<br />

these two reasons, consideration should be given to fixing the<br />

digits in extension at the proximal interphalangeal joint and flexion<br />

at the metacarpophalangeal joint by insertion of threaded<br />

Kirschner wires which are removed after complete wound healing,<br />

at which time the position can be maintained easily with splints 21<br />

62 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: burns<br />

Burns to the palm of the hand should be treated conservatively<br />

with gentle debridement, as they will often heal spontaneously<br />

because of the depth of the skin. In the paediatric population<br />

contractures may develop, either in the acute phase or, years later,<br />

as the scar growth is less than that of the normal tissue.<br />

For the feet, great care must also be taken with excision of fullthickness<br />

eschar in this area, because the extensor tendons are in<br />

very close proximity to the skin. Autograft skin applied to this area<br />

should be of a narrow mesh to avoid hypertrophic scarring, which<br />

can make it difficult to fit shoes. The toes require the same<br />

considerations as the fingers. 21<br />

Rehabilitation<br />

The goals of the rehabilitation process are to maximize function<br />

and appearance of the scars. This is done by trying to counteract<br />

two main physiologic processes, scar hypertrophy and<br />

contracture.<br />

Hypertrophic Scarring<br />

Hypertrophic scarring generally does not develop in burns that<br />

require less than 2 weeks to heal. Hypertrophic scarring develops<br />

in 33% of wounds that take less than 3 weeks to heal, but 78% of<br />

wounds that take more than 3 weeks. It also affects skin grafts.<br />

Hypertrophic scars are thickened, red, and raised scars which can<br />

often be very itchy. Unlike keloids, hypertrophic scars do not<br />

outgrow their boundaries. They will also generally remodel and<br />

regress over time, but this may take a number of years, and<br />

contractures may develop in the interim. Although children<br />

generally heal quickly, they are at higher risk of hypertrophic<br />

scarring if there is delayed healing. In addition, individuals with<br />

darker skin pigmentation are also at greater risk of hypertrophic<br />

scarring and keloids. Tangential excision and grafting of burns that<br />

require greater than 3 weeks to heal can help prevent or reduce<br />

hypertrophic scarring.<br />

Scar compression is the mainstay of non-surgical hypertrophic<br />

scarring prevention and management. This can be achieved with<br />

customized compression garments, or with elastic tensor<br />

bandages. The goal is to have pressures of approximately<br />

25mmHg. If using tensor bandages, they must be wrapped from<br />

distal to proximal, taking care not to cause ischemia or venous<br />

stasis. Using tensors for compression over grafts should be<br />

initiated after grafts are well healed, approximately 2-3 weeks after<br />

grafting. This should continue until scar maturation, which can<br />

take up to 1-2 years, and is gauged by when the scar is softened<br />

and stabilized.<br />

Scar massage can also help with breaking down of excess scar<br />

tissue. This is often done in combination with stretching exercises<br />

to prevent scar contractures. Scar massage should be done 2-3<br />

times per day with a hypo-allergenic lotion or cream, or petroleum<br />

jelly (Vaseline). Moisturizing and massaging the scars, which can<br />

be dry due to the lack of glands in the scar tissue, may be sore at<br />

first, but usually becomes soothing, and can help with the<br />

itchiness of the scars. Massaging must press hard enough to<br />

blanch the pink scars. Maturation and flattening of the scars can<br />

take 1-2 years, particularly in children where the hypertrophic<br />

phase may be longer. Most scars will eventually fade and lose<br />

their pink colour over time, but the 1-2 year time frame may be<br />

longer.<br />

Silicone gel sheets can also be beneficial. The exact mechanism<br />

is unknown, but they appear to help soften the scar. To reap the<br />

benefits, they must be worn for long periods (over 20 hours a day)<br />

to be beneficial. They can be placed under compression<br />

garments, or simply taped on for areas not amenable to<br />

compression. These can be washed daily and reused.<br />

Contractures<br />

Joint contractures are one of the most challenging aspects of burn<br />

management, and are the main source of disability from thermal<br />

burns. Scar contracture is due to activity of the myofibroblasts<br />

which act to contract scars. When the scars are across joints,<br />

particularly flexion joints, these can lead to permanent flexion<br />

deformities. In addition, flexed positions are often positions of<br />

comfort during the acute phase of burn management,<br />

exacerbating the problem. To combat joint contractures,<br />

stretching and splinting is necessary. Stretching and range of<br />

motion exercises should be initiated from the beginning. With initial<br />

edema, movement may be a bit difficult but should be encouraged<br />

with daily exercises.<br />

To combat joint contractures, stretching, careful positioning and<br />

splinting are necessary. Necks should be hyperextended with a roll<br />

under the shoulders. Axillae should be carefully positioned. Upper<br />

thigh/lower abdominal burns require positioning to prevent flexion<br />

of the hips. Stretching and range of motion exercises should be<br />

initiated from the beginning. With initial edema, movement may be<br />

a bit difficult, but should be encouraged with daily exercises.<br />

Splinting<br />

Contractures are the most debilitating residual stigma of burns,<br />

and high-risk patients (deeper burns over flexion joint surfaces)<br />

can easily be identified. Contractures are much easier to prevent<br />

than to fix. Once developed, can be very difficult to manage and<br />

correct. Elevation of the burned limb reduces edema and<br />

facilitates early joint mobilization. Where surgical treatment is<br />

limited by resource issues; hyperalimentation, good dressings,<br />

splinting and aggressive stretching can still make a big difference<br />

to patient outcomes. Equally, surgical results will improve<br />

dramatically with good post-operative splinting and early<br />

mobilization as soon as the grafts are solid.<br />

Splinting should be considered when any loss of extension is<br />

noted across elbows and knees. Hands should be splinted from<br />

the onset. 51 Simple plaster slabs covered in elastic tube bandage<br />

or “stockinet” make excellent volar hand splints, can be wrapped<br />

on with tensor bandages and are re-usable till soiled. Splints are<br />

often applied overnight, allowing for mobilization and function in<br />

the daytime.<br />

There are numerous splinting techniques suggested. Both static<br />

and dynamic splints can be used. Dynamic splints may be better<br />

for reversing any contractures, as they may gain extension, not<br />

only maintain the gains during therapy. However, they are<br />

significantly more costly to produce, and long-term gains have not<br />

consistently been shown. Many local materials have been used to<br />

produce inexpensive splints, including easily malleable aluminum<br />

sheets.<br />

Neck collar braces, or custom thermoplastic splints may be<br />

used to prevent flexion contractures, and stretches should include<br />

both extension and lateral flexion. The splint should be properly<br />

padded to prevent pressure points. There are also alternative<br />

splinting techniques for the neck 52 . Axilla contractures can be<br />

challenging to splint, with various<br />

materials used for “airplane<br />

splints”. Because splinting in<br />

abduction can be uncomfortable<br />

and awkward, this is sometimes<br />

neglected. However, the inability to<br />

abduct the arms leads to<br />

Figure 6: Position of safety<br />

significant morbidity, and it severely<br />

limits overhead activities. 53<br />

The ankle can have contractures in both directions. Burns and<br />

scar contractures to the dorsum are more common, which must<br />

be combated with plantar flexion exercises and splints. However,<br />

the Achilles tendon may also become shortened with a prolonged<br />

planter flexion. For an ambulating patient, this is not a concern.<br />

However, for a patient who is bed-ridden, splinting should be<br />

initially for dorsiflexion to prevent Achilles tendon shortening.<br />

Fingers and hands should be splinted in the position of safety<br />

(Figure 6), with MCPs flexed and IPs extended. If there is a severe<br />

burn over the palmer aspect of the MCP joints, the MP joints can<br />

sometimes be splinted in extension, but it becomes very important<br />

to ensure that daily exercises maintain good flexion of the collateral<br />

ligaments of the MCP joint, which can tighten when in extension.<br />

Oral burns, particularly commissure burns can lead to<br />

complications of microstomia. These can be initially managed with<br />

mouth exercises, and gradually increasing the amount of mouth<br />

opening.Splints can also be fabricated to stretch the<br />

commissures. 54<br />

Surgical release<br />

Surgical release of burn contractures can involve local flaps for<br />

reorientation of the scar, but often also include a skin deficit which<br />

must be filled with a graft or flap. Skin grafts are also more prone<br />

to contractures, and aggressive post-operative therapy much be<br />

implemented. Repeat surgeries may be necessary. Thick (full<br />

thickness if the area is small enough) unmeshed grafts offer less<br />

contracture. Alternatives include artificial dermal substitutes that<br />

will allow decreased contracture with thinner split-thickness grafts.<br />

However, dermal substitutes such as Integra, a bovine collagen<br />

product, are commercial produced and extremely expensive. If<br />

skin or myocutaneous flaps are possible, they offer the advantage<br />

of coverage with minimal contracture and need for repeat surgery.<br />

These include both local flaps such as z-plasties and transposition<br />

flaps, but also pedicled or free vascularized flaps. The surgeons<br />

will require an armamentarium of possible flaps and grafts to apply<br />

to the situation. Figure 7 gives a possible algorithm for selective<br />

various surgical options. 55 Other general principles include the<br />

release of more proximal contractures before distal ones in limbs<br />

with multiple levels involved, such as elbow release followed by<br />

wrist, then fingers. Certain anatomic areas are more prone to<br />

contractures and have specific complications.<br />

Neck contractures<br />

Neck flexion is often associated with webbing of the neck. There<br />

is often a severe shortage of skin, and a significant size skin graft<br />

may be necessary for coverage of the defect after release. Unless<br />

very minor, or featuring a narrow band of scar, these are usually<br />

not amenable to z-plasties. Another challenge for severe neck<br />

contractures is difficulty with intubation. The release of the neck<br />

may need to be done under local anesthetic to allow for neck<br />

Figure 7: An algorithm for the cover of burn contractures of the<br />

extremities, after adequete release: band contracture (ROM =<br />

normal joint rnage of motion)<br />

extension before initiation of general anesthetic and reconstruction<br />

of the defect. If the injury is anterior only, a good alternative for<br />

coverage of the neck is a pedicled latissimus dorsi flap, which<br />

would provide normal skin coverage without risk of contracture<br />

recurrence. 56<br />

Hands<br />

Contractures in the hands include flexion contractures of the<br />

fingers and wrist, web space narrowing of the digits, as well as<br />

hyperextension of the MCP joints.<br />

Finger contractures can sometimes be released with z-plasties,<br />

if the burn area is isolated to the central palmer aspect of each<br />

finger. If z-plasties are used, care should be taken not to cause<br />

excess tension with closures leading to finger ischemia. Release of<br />

prolonged flexion contractures can also have ischemia from<br />

overstretching of shortened neurovascular bundles. Release may<br />

need to be staged, or stretched post-operatively with therapy.<br />

Kirshner wires may be beneficial for the first 1-2 weeks until the<br />

skin graft take is reasonable. They also facilitate the fabrication of<br />

post-operative splints which are best fashioned with the K-wires<br />

still in place. Web-space deepening is particularly important in the<br />

first web-space. A 4-flap or 5-flap z-plasty (Figures 8&9) will allow<br />

deepening of the webspace and increased abduction of the<br />

thumb. A 5-flap z-plasty (also known as a double Z-plasty with V-<br />

Y advancement) allows for more deepening, while a 4-flap allows<br />

for much greater lengthening. These are used primarily in the 1st<br />

webspace. Deepening of the other webspaces is often performed<br />

using techniques for congenital syndactyly, with a skin flaps used<br />

to reconstruct the base of the webspace to prevent future web<br />

creep. Skin grafts are often necessary to fill in the gaps on the<br />

sides of the fingers. 57<br />

Axilla<br />

Axillary scar contractures are also very common. These can at<br />

lengthened (such as tendons or joints), while<br />

others may limit the release to limited stages<br />

serial casting/splinting postoperatively. The<br />

exposure of tendons or nerves in the scar<br />

bed may require a flap rather than graft<br />

coverage. Preservation of the peritenon on<br />

the tendon/peritenon may allow for a<br />

primary skin graft to survive. However, if the<br />

tendon is in an area that requires significant<br />

mobility, the skin graft may tether the tendon<br />

leading to decreased mobility. Caution<br />

should be also taken when putting a skin<br />

graft on an exposed nerve, as this may lead<br />

to complications of neuromas, or<br />

hypersensitivity in the area.<br />

Figure 9: 4-Flap Z-plasty 63<br />

times be treated with a large 4-flap z-plasty, similar to for the first<br />

webspace, or multiple z-plasties or V-Y plasties. 58 Alternatively,<br />

they can sometimes also be managed with release and skin grafts.<br />

The use of skin grafts requires post-operative splinting, often in<br />

airplane splints to prevent recurrence. An alternative may be a<br />

Figure-of-8 splint which also helps to hold the graft in place. 59<br />

Recurrent or very tight contractures may be amenable to local<br />

flaps if the burn is localized to the axilla with sparing of chest or<br />

back tissue. These include latissimus dorsi, or pectoralis<br />

major/minor myocutaneous flaps. 60<br />

Deep structures<br />

Release of the scar may be insufficient for chronic contractures.<br />

Contractures may be limited by deep structures, such as joint<br />

capsules, tendons, or nerves. Some of these may be released or<br />

can lead to corneal abrasions. These can be<br />

graft placement. Thin full-thickness skin can be harvested from the<br />

pre or post-auricular region if available. Microstomia and<br />

commissure burns can be treated initially with splinting and<br />

stretching exercises. Customized splints can be made, preferably<br />

with the ability to slowly expand the mouth. With severe<br />

microstomia, a commissureplasty using mucosa to recreate<br />

Conclusions<br />

Many accomplishments have been made in burn care over the<br />

past several decades, as illustrated below (Figure 10). 31<br />

Encouragingly, these have resulted in steady improvements in<br />

mortality rates.<br />

This progress has also been noted in a number of centres in<br />

resource-poor countries where a multidisciplinary,<br />

global approach to the burn<br />

patient has been embraced; from<br />

specific changes in clinical practice can and<br />

do improve outcomes. As medical<br />

professionals, we must not be paralyzed by the magnitude of the<br />

task ahead. Instead we must think of each small step as a<br />

significant improvement. With focused attention and the<br />

application of evidence-based knowledge, we will see change<br />

both measurable and meaningful in the treatment of burn patients.<br />

Recommendations<br />

The following recommendations capture the key elements of a<br />

simple, but effective approach to better burn management tailored<br />

to developing countries:<br />

✚ Community leaders and burn surgeons must collaborate in<br />

developing local prevention strategies as well as community<br />

education strategies on immediate first aid steps for burn<br />

victims and the critical importance of early transportation to the<br />

nearest source of appropriate medical services.<br />

✚ Medical personnel must be trained in resuscitation; including<br />

aggressive fluid resuscitation, monitoring for airway<br />

compromise, and high flow oxygen, all of which to be initiated<br />

within the first hours in the case of a major burn. The burns<br />

must be assessed for depth, size, need for escharotomy and<br />

risk of inhalation injury on presentation<br />

✚ Both physiotherapy, including early active and passive<br />

movements and splinting for high risk joints and high protein,<br />

high caloric frequent feeds should be in place as of the first<br />

day.<br />

✚ Wound care must be performed daily, with careful attention for<br />

signs of invasive infection. Appropriate analgesia, sterile<br />

conditions and topical antibiotics (SSD) should be used.<br />

✚ Whenever possible, deep second degree burns and third<br />

degree burns should be grafted within 10 days of the injury.<br />

Techniques to minimize blood loss such as tumescence and<br />

tourniquets should be standard practice.<br />

✚ Systemic antibiotics should be reserved for single-dose<br />

immediate pre-operative prophylaxis and treatment of invasive<br />

wound sepsis, tailored if possible to wound culture results and<br />

institutional resistance patterns.<br />

✚ All practicing physicians and surgeons working in areas<br />

without a regional burn center should receive training in skin<br />

grafting.<br />

✚ Blood transfusion should be limited to when physiologic need<br />

exists.<br />

✚ Life-long seizure prophylaxis and patient education regarding<br />

the importance of compliance must be part of burn care<br />

prevention in all epileptic patients. ❏<br />

Cardiovascular risk factor trends<br />

and options for reducing future<br />

coronary heart disease mortality in<br />

the United States of America<br />

One of the objectives of the Healthy People 2010 initiative in the United States of America (USA) is achievement of a 20% reduction<br />

in age-adjusted coronary heart disease (CHD) mortality rates. We examined the potential for changes in cardiovascular risk factors<br />

to achieve that target using a previously validated, comprehensive CHD mortality model. This model integrates information on<br />

trends in all the major cardiovascular risk factors, stratified by age and sex. The potential reductions in CHD mortality within the<br />

projected population of the USA aged 25 to 84 years in 2010 (198 million) from base year 2000 were calculated for three<br />

contrasting scenarios. In the first scenario, if age-adjusted CHD mortality rates observed in 2000 remained unchanged, some 388<br />

470 CHD deaths would occur in 2010. Continuation of recent risk factor trends should result in approximately 19 000 fewer coronary<br />

deaths (some 51 000 fewer deaths attributable to improvements in total cholesterol and men’s blood pressure, decreased smoking<br />

and increased physical activity, minus approximately 32 000 additional deaths attributable to adverse trends in obesity, diabetes<br />

and women’s blood pressure). In the second scenario, success in reaching all the Healthy People 2010 risk factor targets would<br />

achieve approximately 188 000 fewer deaths. In the third, additional reductions in risk factors to the levels already seen in the lowrisk<br />

stratum could potentially prevent approximately 372 000 deaths. Achievement of the Healthy People 2010 targets could almost<br />

halve predicted CHD deaths. Additional reductions in major risk factors could prevent or postpone substantially more CHD deaths.<br />

Coronary heart disease (CHD) accounted for over 450 000<br />

deaths in the United States of America (USA) in 2004. 1,2<br />

The burden of CHD is enormous, affecting more than 13<br />

million people and generating direct health-care costs exceeding<br />

US$ 150 billion annually. 1,2 Since the late 1970s, age-adjusted<br />

CHD mortality rates have been halved in most industrialized<br />

countries including the USA. However, between 1990 and 2000<br />

this decrease diminished, with clear flattening in younger age<br />

groups. 1,2 Many adults in the USA still demonstrate high levels of<br />

risk for cardiovascular disease. Total cholesterol levels exceed 200<br />

mg/dl among more than 100 million adults, approximately 70<br />

million have or are being treated for high blood pressure (a systolic<br />

blood pressure ≥140 mmHg or diastolic blood pressure ≥90<br />

mmHg) and over 50 million people still smoke. 2–4<br />

The Healthy People 2010 (HP2010) initiative promoted by the<br />

government of the USA contains targets for heart disease and<br />

stroke that explicitly address risk factor prevention, detection and<br />

management, along with prevention of recurrent events. HP2010<br />

objectives include a 20% reduction in age-adjusted CHD mortality<br />

rates (from 203 per 100 000 population in 1998 to 162 per 100<br />

000 in 2010).3 They also include specific targets for reducing<br />

cholesterol (to 199 mg/dl), smoking (to 12%), hypertension (to<br />

16%), diabetes (to 6%), obesity (to 15%) and inactivity (to 20%). 3<br />

Inactivity was measured in the Behavioral Risk Factor Surveillance<br />

System of the United States Centers for Disease Control and<br />

Prevention as the proportion of adults engaging in no physical<br />

activity.5 If those targets are achieved, what reduction in CHD<br />

mortality might actually result?<br />

Large meta-analyses and cohort studies have consistently<br />

demonstrated substantial reductions in CHD deaths related to<br />

decreases in each of the major cardiovascular risk factors among<br />

individuals covered by the studies. 6–8 However, it is difficult to<br />

attribute a decline in the mortality rate for an entire population<br />

either to specific risk factor changes or to more effective medical<br />

interventions because favourable trends in both often have<br />

occurred simultaneously. 9,10 Furthermore, risk factor improvements<br />

such as lower blood pressure or cholesterol may be achieved<br />

through medications, lifestyle changes or a combination. 1,2,8–10<br />

A variety of CHD policy models have been developed to<br />

estimate the relative contributions and hence the population<br />

impact of medical and public-health interventions. Good models<br />

are able to integrate and simultaneously consider large amounts of<br />

data on patient numbers, treatments and population risk factor<br />

trends. 9–11 The CHD Policy Model developed in the USA was used<br />

successfully to examined trends in that country between 1980 and<br />

1990 9 and later demonstrated the potential advantages of a<br />

population-based approach to prevention, 12 consistent with<br />

European studies. 13-15<br />

Capewell et al. have subsequently developed, refined and<br />

applied the IMPACT model in a variety of populations. 10,16-19<br />

Approximately 44% of the substantial CHD mortality decline in the<br />

USA between 1980 and 2000 was attributable to changes in<br />

major risk factors and 47% to specific cardiological treatments, 10<br />

similar to findings in other industrialized countries. 16,17,19,20 Three<br />

earlier analyses suggested that further modest reductions in major<br />

risk factors could halve CHD deaths in the United Kingdom of<br />

Great Britain and Northern Ireland. 15,21–23 To determine whether<br />

similar gains may be possible for the population of the USA, or<br />

whether they would be negated by recent dramatic rises in obesity<br />

and diabetes, we used the previously calibrated IMPACT model 10<br />

for the USA to estimate the number of CHD deaths that could<br />

potentially be prevented or postponed in 2010, compared with the<br />

number in 2000. The model was applied to three contrasting<br />

scenarios, the most optimistic of which assumed that the<br />

prevalence of risk factors in the entire population reaches the<br />

levels already reported in its “low-risk stratum”. 24,25<br />

Methods<br />

The IMPACT model aims to explain changes in CHD mortality<br />

rates in a population. It quantifies the contribution from temporal<br />

trends in the major population<br />

risk factors (smoking, high<br />

systolic blood pressure,<br />

elevated total cholesterol,<br />

obesity, diabetes and physical<br />

inactivity) and from medical<br />

and surgical treatments given<br />

to CHD patients. 10,17,26 The<br />

model employs regression<br />

coefficients produced by large<br />

meta-analyses and cohort<br />

studies. 6-8 Each coefficient<br />

quantifies the independent (log linear) relationship between the<br />

absolute change in a specific cardiovascular risk factor, such as<br />

high systolic blood pressure or total cholesterol, and the<br />

consequent change in population mortality rates from CHD (Table<br />

1). 6-8 For each risk factor, the subsequent reduction in deaths in<br />

2010 from base year 2000 could then be estimated as the product<br />

of three variables:<br />

Number fewer deaths = number of CHD deaths observed in<br />

2000 × the risk factor reduction × the specific regression<br />

coefficient exponentiated. 10,22,23<br />

All the coefficients and relative risk values were obtained from<br />

multivariate logistic regression analyses and were assumed to be<br />

independent, having been adjusted for potential confounding from<br />

the other major risk factors. The total deaths prevented could<br />

therefore be summed. Independent regression coefficients were<br />

not available for smoking, diabetes and physical inactivity. An<br />

alternative methodology was therefore used, which involved<br />

population-attributable risk fractions 9,21,22 calculated for the<br />

INTERHEART study, a large, international multivariate analysis that<br />

included data from the USA27 (Table 2).<br />

The original 1980–2000 IMPACT model 10 was extended to 2010<br />

using United States Census Bureau population projections and<br />

mortality data for men and women aged 25–84 years. The number<br />

of CHD deaths (ICD-10: I20-I25) expected in 2010 was then<br />

calculated under three contrasting risk factor scenarios.<br />

Risk factor scenarios<br />

The first scenario assumed that recent risk factor trends would<br />

continue to 2010. Using data from the Third National Health and<br />

Nutrition Examination Survey (NHANES) 1988–1994, NHANES<br />

1999– 2002, and the Behavioral Risk Factor Surveillance System<br />

(1988–2002), 3,4 linear projections were made from 1988–1994<br />

through 1999–2002 to the country’s population in 2010 of recent<br />

objectives. 3 In the absence of specific HP2010 targets for BMI,<br />

total diabetes and systolic blood pressure, we assumed that: (i)<br />

the 15% obesity target would equate to a population mean BMI of<br />

25 kg/m 2 for men and 26 kg/m 2 for women; (ii) the 25 per 1000<br />

population clinically diagnosed diabetes prevalence target would<br />

equate to a total (diagnosed and undiagnosed) type 1 and type 2<br />

diabetes prevalence of 6%; and (iii) the 16% hypertension<br />

prevalence target would equate to a population mean systolic<br />

blood pressure of 119 mmHg, representing a 5 mmHg reduction<br />

from 2000 levels (Table 3).<br />

In the third scenario, mean population risk factors were<br />

assumed to reach levels already observed in the “healthiest”<br />

stratum of cohorts in the USA, as defined by Stamler et al. 24 and<br />

Daviglus et al. 25 Levels for specific risk factors were as follows: (i)<br />

no smoking among men or women; (ii) 175.6 mg/dl (4.54 mmol/l)<br />

total cholesterol for men and 179.6 mg/dl (4.64 mmol/l) for<br />

women; (iii) a mean systolic blood pressure of 115.7 mmHg for<br />

men and 114.7 mmHg for women, representing a 10mmHg<br />

reduction from 2000 levels; (iv) a BMI of 25.5 kg/m 2 for men and<br />

23.6 kg/m 2 for women; (v) zero prevalence of diabetes among<br />

both men and women. 24,25 Physical activity was not specifically<br />

considered by in these studies, 24,25 so we defined the level in the<br />

lowest risk stratum as 100%, with everyone undertaking some<br />

leisure-time physical activity. (Table 3). To preserve the focus on<br />

risk factor changes, we assumed that the proportion of the<br />

population receiving medical and surgical treatments for CHD<br />

would remain constant.<br />

Sensitivity analysis<br />

Because of the uncertainties surrounding some of the estimates,<br />

a multi-way sensitivity analysis was performed using the analysis<br />

of extremes method. 28 Minimum and maximum estimates of<br />

deaths prevented or postponed were generated using minimum<br />

and maximum plausible values for the main parameters: 95%<br />

confidence intervals when available; otherwise, the best value<br />

±20%. 10,22,23,28 The Supplementary Appendix (available at:<br />

http://content.nejm.org/cgi/data/356/23/2388/DC1/1) provides<br />

worked examples of the calculations used in the model plus<br />

further details on the methods and data sources used. 10<br />

Results<br />

Trends and estimates<br />

Approximately 388 000 CHD deaths among people aged 25–84<br />

years would be expected in 2010 if the same age-specific death<br />

rates recorded in 2000 (the base year) were also observed in<br />

2010. This number would represent 15% more than the 338 000<br />

deaths observed in 2000, reflecting population aging<br />

compounded by an increase in population size (Table 4).<br />

Between 1997 and 2002, the overall annual declines observed<br />

in CHD mortality rates were 2% for men and 1% for women.<br />

a Additional deaths shown as a positive value: e.g. (+355)<br />

b Number of deaths from coronary heart disease rounded to nearest 1000 on this and subsequent rows<br />

However, declines were minimal among men younger than 45<br />

years of age, and increases were seen among women in that age<br />

group. Three of the six major risk factors declined between 1988<br />

and 2002, while obesity and diabetes increased. Systolic blood<br />

pressure rates rose among women and fluctuated among men.<br />

Assuming continuation of the same trends, the overall result would<br />

be approximately 19 000 fewer deaths in 2010 than in 2000<br />

(minimum estimate 10 000 and maximum estimate 25 000). This<br />

represents some 51 000 fewer deaths because of improvements<br />

in total cholesterol and men’s blood pressure, less smoking and<br />

increased physical activity, minus approximately 32 000 additional<br />

deaths attributable to adverse trends in obesity, diabetes and<br />

women’s blood pressure (Table 5).<br />

Approximately 188 000 fewer CHD deaths than in 2000<br />

(minimum 129 000, maximum 252 000) could be achieved by<br />

reaching the specific reductions in cardiovascular risk factors<br />

called for in HP2010: (i) approximately 40 000 fewer deaths if<br />

population mean cholesterol levels declined to 199 mg/dl (5.15<br />

mmol/l) among both men and women; (ii) approximately 26 000<br />

fewer deaths if the smoking prevalence fell to 12% among both<br />

men and women; (iii) approximately 48 000 fewer deaths,<br />

assuming a decrease in mean systolic blood pressure to 119.4<br />

mmHg among men and 118.9 mmHg among women<br />

(representing a 5 mmHg reduction in all age groups); (iv)<br />

approximately 12 000 fewer deaths, assuming an increase in<br />

physical activity rates (to 80% among both men and women); (v)<br />

approximately 17 000 fewer deaths, assuming a substantial<br />

decrease in BMI to 25.0 kg/m 2 for men and 26.0 kg/m 2 for women;<br />

(vi) approximately 44 000 fewer deaths, assuming a substantial<br />

decrease in total diabetes prevalence to 6% among both men and<br />

women. If the ideal scenario were achieved, with mean population<br />

cardiovascular risk factors reduced substantially to levels already<br />

observed in the healthiest stratum of cohorts, 24,25 approximately<br />

372 000 CHD deaths (minimum 281 000, maximum 507 000)<br />

could be prevented or postponed (Figure 1). The 372 000 fewer<br />

deaths would be distributed as follows: (i) approximately 103 000<br />

fewer deaths if population mean cholesterol levels declined to<br />

175.6 mg/dl (4.54 mmol/l) among men and 179.6 mg/dl (4.64<br />

mmol/l) among women; (ii) approximately 60 000 fewer deaths if<br />

smoking prevalence fell to zero; (iii) approximately 83 000 fewer<br />

deaths, assuming a 10 mmHg decrease in mean systolic blood<br />

pressure to 115.7 mmHg for men and114.7 mmHg for women; (iv)<br />

approximately 34 000 fewer deaths if all men and women were<br />

physically active; (v) approximately 21 000 fewer deaths, assuming<br />

a decrease in BMI to 25.5 in men and 23.6 in women; (vi)<br />

approximately 72 000 fewer deaths, assuming a zero prevalence<br />

of diabetes (Table 5).<br />

Estimated mortality benefits<br />

Under the scenario in which current trends continued,<br />

approximately 16 000 fewer deaths would occur among men and<br />

3000 among women. In the two more optimistic scenarios, men<br />

would consistently benefit more than women, gaining 54% of the<br />

182 000 fewer deaths under the HP2010 reductions scenario and<br />

62% of the 372 000 fewer deaths if low-risk stratum levels are<br />

assumed (Table 5). Gains would predominantly occur among men<br />

aged 45–84 years and among women aged 65–84 years (Figure<br />

2). Of the 372 000 fewer deaths in the most optimistic scenario,<br />

252 000 (68%) would represent premature deaths avoided, that is,<br />

deaths among those under 75 years of age (Table 6). Extensive<br />

sensitivity analyses examined the impact of higher and lower<br />

values for model parameters. 28 Changing the values influenced the<br />

number of deaths postponed or prevented but did not alter the<br />

relative contribution of each risk factor (Table 5, columns 5 and 6).<br />

Thus, regardless of whether best, minimum or maximum<br />

estimates were considered, the most substantial contributions<br />

came from the changes in cholesterol, blood pressure and<br />

smoking (Table 5).<br />

Discussion<br />

Success in achieving the HP2010 targets could almost halve<br />

predicted CHD deaths in 2010, or indeed in 2015. Our findings are<br />

reassuringly consistent with earlier studies in the England, 23<br />

Scotland 22 and the USA 12 . In the United Kingdom, a modest<br />

reduction in mean population cholesterol level from 225 mg/dl to<br />

200 mg/dl could reduce CHD deaths by approximately half. 14,15,24 In<br />

contrast, a rather optimistic 25% reduction in the prevalence of<br />

obesity would probably prevent just 2% of CHD deaths. 15,24 A<br />

corresponding 25% reduction in the prevalence of inactivity might<br />

prevent 1% of CHD deaths. 15,29<br />

Although CHD death rates have been falling in the USA for four<br />

decades, they are now plateauing in young men and women. 2<br />

Recent declines in total cholesterol have been modest, blood<br />

pressure is now rising among women and obesity and diabetes are<br />

rising steeply. Furthermore, population aging will increase the<br />

numbers of CHD deaths in that country and elsewhere. 30 There is<br />

no room for complacency. Continuation of recent risk factor trends<br />

should result in approximately 20 000 fewer coronary deaths in<br />

2010 than in 2000. This reflects some 50 000 fewer deaths<br />

expected from improvements in total cholesterol, smoking, physical<br />

activity and male blood pressure, but more than half of the gain is<br />

negated by approximately 30 000 additional deaths attributable to<br />

increases in rates of obesity and diabetes, plus systolic blood<br />

pressure increases among women. Increasing treatments could<br />

not compensate for these worsening risk factors. In 2000, barely<br />

40% of eligible patients received appropriate therapies. 10 Even<br />

raising this proportion to an optimistic 50% would only postpone<br />

approximately 60 000 additional deaths in 2010. 31<br />

Successfully achieving the specific risk factor reductions<br />

proposed in the HP2010 targets could prevent or postpone<br />

approximately 190 000 CHD deaths. This would potentially halve<br />

the mortality burden seen in 2000. The HP2010 objectives for<br />

cholesterol and physical activity remain potentially attainable.<br />

However, attaining the targets for obesity, diabetes and female<br />

blood pressure appear more challenging because of the need to<br />

actually reverse recent adverse trends. 3 Successfully reducing<br />

population risk factor levels to those already seen in<br />

the healthiest (lowrisk) stratum could result in<br />

approximately 370 000 fewer CHD deaths among<br />

people aged 25–84 years. This figure would represent<br />

a 96% decrease compared to the 2000 baseline of<br />

388 000 1,3 and is somewhat larger than the 85%<br />

reduction predicted by other studies. 24,25 Although<br />

probably an overestimate, the results for this third<br />

scenario show an aspirational ideal to highlight<br />

potential future gains. However, the “low-risk stratum”<br />

in the population of the USA remains frustratingly<br />

small, even when defined only by smoking, blood<br />

Achieving risk factor reductions<br />

Although fashionable, screening and treating high-risk<br />

individuals would necessitate medicating 15% to<br />

25% of all adults. 34,35 Furthermore, the key goal is not<br />

intervention but sustained risk factor reductions. 35 The<br />

whole population approach described by Rose 13<br />

appears both more effective and cost-effective. 13–15<br />

Similar conclusions have been reported previously in<br />

Dutch, Finnish and American cohorts. 12,35<br />

Lowering cholesterol should therefore remain a<br />

priority in the USA, as it offers a potentially powerful<br />

1% mortality reduction for every 1 mg/dl decrease in<br />

total cholesterol. 6 Large cholesterol declines have<br />

already been achieved by comprehensive national<br />

policies elsewhere (-20% in Finland 18 and -15% in<br />

Mauritius 36 ). In contrast, in the USA between 1988<br />

and 2004 total cholesterol fell barely 3% in adults<br />

(from 206 to 201 mg/dl). 37 Furthermore, these levels<br />

remain well above the optimal, prompting recent<br />

national dietary policies to further reduce total<br />

cholesterol levels. 2,3,38<br />

Innovation in clinical specialities: cardiovascular disease<br />

Smoking prevalence remains above 20% overall in the USA and<br />

is even higher in certain groups. This represents substantial room<br />

for improvement. Success in reducing tobacco use requires two<br />

comprehensive strategies: preventing young people from starting<br />

to smoke, and promoting cessation among smokers. 39 Examples<br />

of successful efforts include intensive antismoking programmes in<br />

California (USA); 40 advertising bans in Finland, Iceland and Norway;<br />

and smoke-free environments legislation in Ireland, Italy, Scotland<br />

and New York City in the USA. 41 It is encouraging that many more<br />

states in the USA are now passing laws requiring smoke-free<br />

environments. 41 The recent blood pressure trends in women are<br />

alarming. This is a powerful risk factor; every 1 mmHg reduction in<br />

systolic blood pressure could prevent approximately 10 000 CHD<br />

deaths each year in the population of the USA. 7 Furthermore,<br />

population blood pressure has been decreasing in most<br />

industrialized countries in recent decades, reflecting dietary trends<br />

rather than use of medications. 42–44 The American Public Health<br />

Association has called on industry to reduce the salt content of<br />

processed food over the next decade, which could contribute to<br />

meeting the dietary guidelines for daily sodium intake of less than<br />

2300 mg. 44,45<br />

Our analysis suggested that the current adverse trends in the<br />

USA – increases in obesity and diabetes rates and blood pressure<br />

in women – will probably cause approximately 30 000 additional<br />

CHD deaths in 2010. Obese individuals with pre-diabetes can<br />

benefit from a combination of diet, exercise advice and<br />

behavioural therapy, 46 but prevention is preferable. Yet today’s<br />

obesogenic environment is reinforced by powerful commercial,<br />

political, economic and social factors, 47 and thus reversing these<br />

trends will require substantial efforts and appears daunting. 2,3,32<br />

Recent increases in physical activity in the USA are encouraging,<br />

echoing trends in Canada, Finland and elsewhere. 5,18,48 Although<br />

engaging in adequate physical activity confers many health<br />

benefits, our analyses found that the potential reductions in CHD<br />

mortality appeared modest in the USA, as elsewhere. 15,23<br />

Interventions promoting activity among individuals seldom show<br />

long-term sustainability. 48 However, physical activity in populations<br />

may be increased by 4% to 9% through multiple interventions. 23,49<br />

The IMPACT model<br />

Our current analyses used the validated IMPACT model for the<br />

USA. 10 Recent high-quality data from NHANES and other large<br />

national studies reflected many events in a very large population.<br />

The model is comprehensive and transparent; it uses recent,<br />

reliable and reasonably precise age-specific regression coefficients<br />

from substantial meta-analyses 6,7 and relative risk values obtained<br />

from the large INTERHEART study. 27 Every key assumption is<br />

addressed and justified in the Supplementary Appendix (available<br />

at: http://content.nejm.org/cgi/data/356/23/2388/DC1/1). All<br />

models are simplifications of reality, with clear limitations. First, this<br />

model considered only mortality, not morbidity. However, our<br />

estimates of fewer deaths can easily be translated into a 12-fold<br />

increase in life-years gained. 50 Second, the model only explained<br />

91% of the mortality decrease, leaving 9% unexplained. Third,<br />

several assumptions were necessary, for instance, that any delay<br />

in mortality reduction (lag time) would be relatively unimportant<br />

over a 10-year scenario. 10,17,23<br />

However, extending the projections from 2000–2010 to<br />

2000–2015 would generate very similar results. Although all<br />

coefficients were independent, coming from multivariate logistic<br />

regression analyses, 6,7,27 some may not have been fully adjusted<br />

and thus “residual confounding” may remain, along with some<br />

imprecision. 10 Furthermore, the population-attributable risk<br />

approach may have slightly overestimated the contributions of<br />

diabetes, smoking and physical activity. Some net overestimation<br />

of benefits is thus possible, particularly for the ideal scenario.<br />

Conversely, underestimation was also possible because the model<br />

assumed similar change across the population.<br />

Larger reductions among older, more motivated individuals with<br />

higher mortality rates might generate greater benefits. Model<br />

development and comparisons with other models may be useful,<br />

along with consideration of “novel” risk factors, such as high levels<br />

of C-reactive protein. 2,3,51 It may also be useful for future studies to<br />

address economic and ethnic analyses and seek to validate the<br />

model using 2010 data when it becomes available. However, our<br />

rigorous sensitivity analyses were reassuring and suggested that<br />

the key findings are unlikely to change substantially. 10,17,23 Moreover,<br />

even crude estimates are potentially valuable for planners and<br />

policy-makers. In conclusion, implementing evidence-based<br />

policies to better control tobacco use and achieve healthier diets<br />

could potentially halve future CHD deaths in the United States of<br />

America. ❏<br />

The breast service psychosocial<br />

model of care project<br />

ARTICLE BY LAUREN K WILLIAMS PhD<br />

Research Fellow, Clinical Research Department, Melbourne IVF and The Royal Women’s <strong>Hospital</strong>, East Melbourne, Victoria, Australia<br />

G BRUCE MANN MB BS, PhD, FRACS<br />

Professor, University of Melbourne, and Director of The Breast Service, Royal Melbourne <strong>Hospital</strong> and Royal Women’s <strong>Hospital</strong>,<br />

Parkville, Victoria, Australia<br />

Objective: It has been consistently demonstrated that many women with breast disease will experience psychosocial<br />

distress at some stage along the patient journey. Psychosocial care has recently gained more prominence and is<br />

increasingly recognised as an important aspect of care offered to patients with breast cancer. The purpose of this project<br />

was to develop a model that improved the way psychosocial services were provided to patients. The aim of this paper is to<br />

describe the process in developing this psychosocial model of care for patients with breast disease.<br />

Methods: Using in-depth semi-structured interviews with a sample of patients and staff, we examined psychosocial<br />

concerns experienced by breast patients and the factors associated with the effective assessment and delivery of<br />

psychosocial care. The project was approved by the Royal Women’s hospital ethics secretariat as a quality assurance<br />

project.<br />

Results: An inductive analysis of staff responses indicated that a standardised screening and referral pathway was needed<br />

in a context of well defined staff roles and a multidisciplinary team environment. An inductive analysis of patient responses<br />

indicated that psychosocial concerns were common, but varied, and a tailored approach to the provision of psychosocial<br />

care was warranted.<br />

Discussion: In line with these findings, a standardised assessment and referral pathway was developed for The Breast<br />

Service that may be extended for use in other clinical settings and tumour streams.<br />

Over 12 000 women are diagnosed with breast cancer in<br />

Australia each year. 1 Unsurprisingly, psychosocial distress<br />

plays a significant role in the journey experienced by<br />

women diagnosed with this disease. Many of the common<br />

psychosocial concerns of women with breast cancer include body<br />

image disruption, sexual dysfunction, treatment-related anxieties,<br />

depression, marital/partner communication and relationship<br />

difficulties, and existential concerns regarding mortality. 2-4 Although<br />

many women will encounter and manage some degree of<br />

psychosocial distress following diagnosis, it is estimated that as<br />

many as 30% of women will experience episodes of persistent<br />

psychosocial distress that will interfere with their ability to cope<br />

with cancer treatment and life in general. 2,4<br />

Psychosocial interventions such as support from a nurse/breast<br />

care nurse, exercise, telephone counselling, computer/online<br />

support, psychological and psychiatric care and social supports<br />

have all been found to improve the psychosocial status of women<br />

diagnosed with breast cancer. 5-7 As a result, the clinical practice<br />

guidelines from the National Health and Medical Research Council<br />

of Australia for the psychosocial care of adults with cancer 3<br />

highlight the need for further research regarding “strategies to<br />

improve the detection of psychological difficulties in people with<br />

cancer” and “optimal methods for psychosocial referral and<br />

practice strategies to improve uptake”. Enhanced knowledge<br />

about the best way to detect and respond to patients’<br />

psychosocial needs is vital in empowering and equipping health<br />

professionals with the necessary skills and resources to help<br />

patients with the range of psychosocial issues that arise along the<br />

breast cancer treatment continuum.<br />

Setting<br />

Recently, the Royal Women’s <strong>Hospital</strong> and Royal Melbourne<br />

<strong>Hospital</strong> breast services merged to form The Breast Service in an<br />

attempt to connect existing resources and provide a more<br />

comprehensive breast cancer service. Strategies to detect and<br />

respond to patients’ psychosocial needs were identified as a key<br />

priority area for The Breast Service. Before the merging of<br />

services, psychosocial care coordination differed between sites<br />

Box 1: Issues with the psychological screening tool identified by staff and patients<br />

Issues identified by The Breast Service staff<br />

■ Staff not accessing the completed supportive care tool (SCT) in patient’s medical file<br />

■ More specialised tools needed for specific areas of concern<br />

■ Not specific to breast cancer/some questions not relevant<br />

■ Only used once. Supplement testing/brief version needed at different stages of the disease<br />

■ Some questions not included to screen for identified psychosocial concern (eg, body image)<br />

■ Absence of criteria for referral (eg, if patient answers “yes” to certain questions what is the process for referral? Criteria needed to<br />

facilitate consistency between clinicians)<br />

■ Questions regarding patient strengths to use for possible referral/support<br />

■ Section needed for patient comments<br />

■ Dichotomous responses (eg, yes/no) create limitations<br />

■ Area needed to record referral details/outcome. Possibly useful to combine details from referral form to SCT. Expansion of referral<br />

options<br />

■ Unclear psychometric validity<br />

■ Does not assess all risk factors<br />

Issues identified by The Breast Service patients<br />

■ Include questions that ask women whether they wanted to be linked in with a group<br />

■ Tailor SCT to patient’s individual situation given that some questions are not relevant<br />

■ Administer the SCT later given that concerns are greater after surgery (it is generally administered at preadmission clinic [PAC])<br />

■ Administer the SCT twice, rather than once at PAC. Some experience concerns at later stages than before surgery and others<br />

don’t recognise their issues until later stages of the disease<br />

■ Include body image questions<br />

and was largely managed by the breast care nurses. Previous<br />

research has highlighted that a range of health professionals is<br />

optimal in assessing and managing the psychosocial needs of<br />

women diagnosed with breast cancer and to support breast care<br />

nurses who, in some cases, are not trained in making<br />

psychosocial assessments and referrals for patients. Furthermore,<br />

before the merging of services, the screening tool used to detect<br />

psychosocial concerns (entitled supportive care tool [SCT]) was an<br />

amalgamation of items from instruments utilised in other health<br />

care settings. Before the development of the current project, the<br />

SCT had not been evaluated since it was implemented into The<br />

Breast Service. A psychosocial working group and steering<br />

committee was developed to address challenges and<br />

opportunities arising from the merging of the two services, and<br />

involved clinicians from the departments of psychology, psychiatry,<br />

medicine, nursing, social work, pastoral care, women’s services<br />

and music therapy. A consumer representative was included and<br />

a project worker appointed to coordinate and execute the project<br />

objectives.<br />

Objectives<br />

The aim of the psychosocial model of care project was to develop<br />

a standardised way of screening for psychosocial distress and<br />

referring patients to the most appropriate clinician(s) and supports.<br />

The first objective of the project was to provide a reflection of the<br />

strengths and weaknesses of the current model of psychosocial<br />

care from relevant clinicians and to generate ideas on the most<br />

effective way to merge and coordinate existing services. The<br />

second objective was to provide a reflection from consumers<br />

regarding their psychosocial needs, the level of psychosocial<br />

support they received and their perceptions and opinions on the<br />

structure and delivery of the current psychosocial model of care<br />

from The Breast Service.<br />

Consultation with health professionals<br />

Methods<br />

A total of nineteen staff members who had (or wanted to have) a<br />

role in the screening, assessment and treatment of patients were<br />

interviewed by the project worker. Staff were recruited from social<br />

work, pastoral care, psychology, psychiatry, medicine, nursing and<br />

community support services (eg, BreaCan). A semi-structured<br />

interview guide was developed which focussed on (a) the method<br />

for screening and referring patients, (b) the role of different staff in<br />

providing psychosocial care, and (c) issues, barriers or concerns<br />

with the provision of psychosocial care. Data were analysed<br />

qualitatively using inductive thematic analysis. The project was<br />

approved by the Royal Women’s hospital ethics secretariat as a<br />

quality assurance project.<br />

Results<br />

It was found that the existing method of screening for<br />

psychosocial needs of patients with breast cancer relied heavily on<br />

the breast care nurses. Completion of a screening tool by patients<br />

at the time of initial diagnosis and surgical treatment was viewed<br />

as beneficial for identifying and recording psychosocial concerns,<br />

however the screening process relied on breast care nurses to<br />

administer the tool, evaluate the results and generate referrals at<br />

their discretion. In addition, The Breast Service staff identified<br />

several issues with the SCT (Box 1). Although the role of breast<br />

care nurses in screening psychosocial needs was viewed by most<br />

as valuable, it was commonly agreed that psychosocial<br />

assessment from additional health professionals would enhance<br />

the validity of the screening procedure. In addition, it was<br />

suggested that periodic rescreening was required to identify those<br />

with particular psychosocial needs that emerge subsequent to<br />

initial diagnosis and surgery.<br />

Consultations with patients attending The Breast Service<br />

The second step of the project was to consult patients about their<br />

psychosocial concerns and supports they received from The<br />

Breast Service staff.<br />

Methods<br />

A total of thirteen women diagnosed with breast cancer attending<br />

The Breast Service participated in either a focus group or<br />

individual interview. The age of participants ranged from 33 to 87<br />

years and four women were from non-English speaking<br />

backgrounds. A semi-structured interview guide which contained<br />

open-ended questions that assessed patients’ psychosocial<br />

concerns and their experience with The Breast Service<br />

(psychosocial screening and referral procedures) was developed.<br />

Patients were recruited from a list of all patients that had<br />

attended/were attending The Breast Service for the last 6 months.<br />

Interviews were conducted at The Royal Women’s <strong>Hospital</strong> in a<br />

private room and were later transcribed to facilitate coding and<br />

analysis. Data were analysed qualitatively using inductive thematic<br />

analysis.<br />

Results<br />

The most commonly reported psychological concerns were<br />

anxiety and depression. Anxiety was reportedly heightened at<br />

diagnosis, between appointments while waiting for results, before<br />

chemotherapy and in social situations for those with visual signs of<br />

cancer, such as hair loss. Patients reported feeling depressed<br />

during treatment, particularly those patients having chemotherapy.<br />

Other reported psychosocial concerns included body image<br />

concerns, relationship issues with their partners, family and<br />

friends, and concerns with mortality, survival and recurrence. Eight<br />

of 13 women interviewed (61.5%) had completed the screening<br />

tool, with most reporting no issues or distress in answering the<br />

questions. Specific comments are shown in Box 1. Psychosocial<br />

support accessed by patients varied. Some women reported<br />

accessing counsellors, psychologists and social workers. These<br />

services were offered through The Royal Melbourne <strong>Hospital</strong> or<br />

privately. Other women reported that they felt comfortable<br />

knowing that these supports were available, however were not<br />

ready or did not feel they would be able to assist them with their<br />

concerns. These women relied on community, family, peer and<br />

individual supports. Some women felt uneasy or awkward about<br />

attending group settings with strangers and would prefer<br />

alternative supports such as email, telephone or a casual<br />

unstructured group setting. These results suggest the individuality<br />

of women’s support needs and the need for a wide range or<br />

services that can address different concerns at different stages of<br />

the disease.<br />

The Breast Service Model of psychosocial care<br />

Based on the outcomes of this project, a revised model for the<br />

assessment and delivery of psychosocial care was developed and<br />

is currently being implemented. As highlighted in Box 2, and<br />

consistent with the previous pathway, at the first suitable visit<br />

(preferably soon after diagnosis), the breast care nurse uses a<br />

screening tool to identify patients who are potentially in need of<br />

more extensive assessment and intervention. The new screening<br />

tool combines a risk factor checklist, i a distress thermometer<br />

(0–10 ranking of distress) and a “yes/no” checklist of<br />

items/concerns; which differs from the original screening tool that<br />

relied solely on the latter. The patient is then discussed at a newly<br />

developed multidisciplinary psychosocial team meeting where a<br />

referral is made if appropriate. Review of patients and subsequent<br />

referrals also occurs in this forum. Given that some patients<br />

reported experiencing psychological concerns such as anxiety<br />

and depression and body image issues, referral options were<br />

extended to include a clinical psychologist, psychiatrist and a<br />

sexual counsellor. A music therapist is also available to assist<br />

patients.<br />

Unlike previously, where the screening tool was only<br />

administered once at initial presentation, the distress thermometer<br />

and checklist is administered again during and after definitive<br />

treatment. Re-presentation of the same patient occurs if significant<br />

distress or psychosocial need subsequently appears. Accurate<br />

execution of the revised pathway is overseen by the director of<br />

The Breast Service and staff attending the multidisciplinary<br />

meeting. Furthermore, patient results (completed screening tool,<br />

referrals forms, and related progress notes) are now inserted into<br />

the patient’s medical file to ensure accessibility by all relevant<br />

health professionals.<br />

Limitations and discussion<br />

One of the main challenges of this project was to build a team of<br />

clinicians with adequate time and resources committed to<br />

assisting with the project. The development of a working group,<br />

steering committee and mutually agreed project plan was the<br />

fundamental key to initiating this process. Staff provided the<br />

project worker with background information, details of current<br />

psychosocial practice and feasibility of new ideas. Another<br />

challenge was delegating and executing tasks, both in the<br />

development and implementation stages of the project.<br />

Clarification was particularly needed around “who is doing what<br />

and how”. These decisions are best made in the working group<br />

meetings, using existing staff and therefore reducing the need for<br />

additional resources. Furthermore, it proved pivotal to the<br />

cohesion and sustainability of the working/steering group that after<br />

each fundamental stage of the project (eg, focus groups) the<br />

execution of the findings was communicated to all relevant staff in<br />

an interactive forum (eg, email reports, meetings, in-services or<br />

workshops).<br />

Conclusion<br />

In summary, the psychosocial model of care project has<br />

transformed the way psychosocial care is provided to patients<br />

attending The Breast Service. We have implemented a<br />

standardised screening, assessment and referral process and a<br />

multidisciplinary team to provide a service of psychosocial care to<br />

all patients. Decisions about assessment, referrals and treatment<br />

no longer rely solely on the breast care nurse. Instead,<br />

collaborative recommendations are made for the patient in a forum<br />

i<br />

National Breast and Ovarian Cancer Centre and National Health and Medical<br />

Research Council guidelines for the psychosocial care of patients with cancer<br />

recommends assessing these risk factors to alert practitioners about certain subgroups<br />

of potentially “at-risk” patients.<br />

that can ensure adequate follow-up and execution of accurate and<br />

targeted referrals. An evaluation of the revised process is planned.<br />

It is envisaged that these findings could assist researchers and<br />

clinicians with the process of developing a psychosocial<br />

assessment and referral pathway. The psychosocial model of care<br />

can also be adapted and utilised in other clinical settings where<br />

psychosocial distress and morbidity is likely. The psychosocial<br />

model of care is already being implemented in the gynaecological<br />

service and ward nurses are being trained in administering the<br />

screening tool. As the results from this quality assurance project<br />

suggest, strategies for detecting and responding to the<br />

psychosocial needs of patients is a vital and achievable<br />

component to the provision of health care. ❏<br />

Supporting cancer control for<br />

Cancer Councils<br />

As in other developed countries, the Australian population is ageing, and cancer rates increase with age. Despite their<br />

substantially lower life expectancy, Indigenous Australians are also experiencing concerning cancer statistics, characterised by<br />

increasing rates, later diagnosis, higher mortality, and lower participation in screening than the non-Indigenous population.<br />

Eighteen months after the first national Indigenous Cancer Control Forum, this environmental scan within the statebased Cancer<br />

Councils was undertaken to map activities in service provision in Indigenous cancer control with a view to sharing the lessons<br />

learned. The findings show that although most of the organizations had tried to work with Indigenous communities on cancer<br />

issues, there have been difficulties in building and sustaining relationships with Indigenous organizations. Lack of having<br />

Indigenous staff internally, few Indigenous-specific resources, and few planned, long-term commitments were some of the<br />

major impediments. Some of these limitations can easily be overcome by building and improving regional or local partnerships,<br />

providing cultural awareness training to internal staff, and by building the capacity of Indigenous organizations. Health<br />

promotion projects of the Cancer Councils directed at Indigenous people could be more effectively implemented with such<br />

considerations.<br />

What is known about the topic? For many years cancer was not considered a high priority issue for Indigenous Australians as a<br />

consequence of social and other health issues. Cancer incidence and death rates of Indigenous Australians have been unclear<br />

as there has been limited epidemiological information and misclassification of Indigenous status. It is now evident that the<br />

pattern of cancer differs for Indigenous Australians, and Indigenous people tend to be diagnosed later, have poorer<br />

participation in treatment and a higher mortality rate for any equivalent stage of diagnosis.<br />

What does this paper add? This paper presents a snapshot of the staffing, projects, programmes and activities of the state<br />

Cancer Councils in early 2006 in terms of efforts to progress cancer control issues focussing on Indigenous Australians. Most<br />

successful initiatives began by establishing a relationship and working over the longer term to sustain programme activity.<br />

What are the implications for practitioners? Insights from the analysis of progress in the cancer field are relevant and<br />

applicable to practitioners in other areas of health where mainstream services have a role to improve the health of Indigenous<br />

communities.<br />

The number of recorded cancer deaths in Australia continues<br />

to increase, attributed in part to the increase in cancer<br />

incidence that occurs in an ageing and an expanding<br />

population. 1,2 Until recently, cancer was seldom identified as a<br />

priority health issue for Aboriginal and Torres Strait Islander<br />

(hereafter Indigenous) Australians. i, 3 The immediate health and<br />

welfare problems of Indigenous Australians across the lifecourse<br />

are well <strong>document</strong>ed, 4-6 and these may have distracted attention<br />

from the fact that cancer has become one of the major causes of<br />

death for these people. Interest about cancer among Indigenous<br />

populations may also be affected by their lower incidence of many<br />

cancers and their shorter life expectancy. Moreover, cancer rates<br />

in Indigenous Australians may under-represent the real burden<br />

because of misclassification and under-ascertainment of<br />

Indigenous status. 7-9<br />

i<br />

Australia has two groups of Indigenous populations: Aboriginal, and Torres Strait<br />

Islanders. In this paper, we will use the term “Indigenous” to refer to both Aboriginal<br />

and Torres Strait Islander peoples.<br />

Innovations and clinical specialities: oncology<br />

Nevertheless, available data show that Indigenous Australians<br />

are experiencing an increasing rate for some cancers. 3 For almost<br />

all cancers, they experience later diagnosis, lower 5-year survival<br />

and a higher mortality rate than non-Indigenous Australians. 10<br />

Indigenous women have lower participation in mammography and<br />

Pap smear screening than non-Indigenous women. 11,12 It has also<br />

been reported that the overall response rate was significantly<br />

lower for Indigenous people than the general population in the<br />

Bowel Cancer Screening Pilot Program that ran between<br />

November 2002 and June 2004 at three sites in Australia. 13<br />

Moreover, while the last two decades have seen a 30% reduction<br />

in cancer mortality rates in Australia, there has been little impact<br />

upon Indigenous cancer mortality. 14 The need to prioritise cancer<br />

prevention and control was recognised in the National Indigenous<br />

and Torres Strait Islander Health Strategy 2001, where cancer was<br />

<strong>document</strong>ed as one of three major chronic diseases for<br />

Indigenous Australians. 15<br />

The first national forum to discuss Indigenous cancer issues,<br />

held in Darwin in August 2004, highlighted various gaps that exist<br />

around responding appropriately to these issues. Many strategies<br />

were proposed to improve their poorer cancer outcomes.<br />

Increased government funding, boosting research on cancer<br />

among Indigenous Australians by enhancing their ownership over<br />

the data, and involving them in partnership with non-Indigenous<br />

health professionals to ensure appropriate service design and<br />

delivery mechanisms were a few of the significant<br />

recommendations. At the conclusion of the forum, the peak nongovernment<br />

organizations providing advocacy for prevention and<br />

care for cancer in Australia.<br />

The Cancer Council Australia and its statebased affiliates,<br />

committed to factoring Indigenous issues into their policy<br />

development and advocacy for cancer prevention and care. 14 This<br />

paper summarises the findings of an environmental scan of current<br />

and past programmes and practice in Indigenous cancer control<br />

by state and territory member organizations of The Cancer Council<br />

Australia. It was primarily undertaken to inform the deliberations of<br />

The Cancer Council Western Australia (TCCWA) on its potential<br />

role and contribution in improving cancer-related services for<br />

Indigenous people in WA. Environmental scanning is a method<br />

most commonly used in business but is quite popular in the health<br />

care sector around the world, 16-18 and is used to identify emerging<br />

issues within the broader economic and political environment. 19 It<br />

is similar to situation analysis in which a review is undertaken of<br />

health strategies and policies, institutional support systems,<br />

programmes and interventions with the aim of strengthening<br />

health reform and health systems. It differs from audits which<br />

generally evaluate performance and are aimed at ascertaining the<br />

validity and reliability of information as part of quality control<br />

processes. Morrison argues that environmental scanning is a<br />

method that enables decision makers both to understand the<br />

external environment and the interconnections of its various<br />

sectors and to translate this understanding into an institution’s<br />

planning and decision-making processes. 20 The advantage of<br />

environmental scanning for organisational leaders is that knowing<br />

both the internal and external environment in which the<br />

organisation operates is helpful in planning their future course of<br />

action. 21<br />

The scan was undertaken to identify various Indigenous-specific<br />

programmes and experiences of the Cancer Councils of Australia<br />

12–15 months following the Darwin forum. This paper highlights<br />

the key issues, learning, successes and limitations of related<br />

initiatives that have been undertaken by the state Cancer<br />

Councils.<br />

Methods<br />

Environmental scanning was agreed to be a suitable method for<br />

learning about how a range of organizations across the sector had<br />

approached supporting Indigenous cancer control approaches<br />

and gathering information about successful initiatives and efforts<br />

that had been less productive, and this approach was accepted<br />

by a Steering Committee and approved by the Curtin Health<br />

Research Ethics Committee.<br />

An initial approach letter was mailed to the Chief Executive<br />

Officers/Directors (CEOs) of all the Cancer Councils, outlining the<br />

background to the survey. They were also requested to nominate<br />

appropriate staff members who could be interviewed about their<br />

organizations’ past or present initiatives to improve Indigenous<br />

engagement with cancer issues and to pass the background<br />

information about the study on to those they nominated. When the<br />

individuals were contacted and nominated others, these additional<br />

nominees were also interviewed if available and willing. A copy of<br />

the letter sent to their CEO was provided to the participants<br />

beforehand.<br />

Semi-structured interviews, either face-to-face or by telephone,<br />

were undertaken with the key nominated staff (Indigenous and<br />

non-Indigenous). The interview was based upon a theme list<br />

developed following a review of relevant literature and discussion<br />

within the research team. The list was also discussed with<br />

Indigenous colleagues and forwarded to a Steering Committee<br />

established to oversee the project of which this scan was a<br />

component. Key areas focusing on Indigenous Australians that<br />

were considered during the interviews, included: cancer<br />

prevention and education; cancer support services for Indigenous<br />

health organizations; healthcare delivery (workforce/access to<br />

healthcare services); research; advocacy/policy and human<br />

resources and any cross-organisational initiatives. Interviews were<br />

taped with the permission of participants, and the responses were<br />

coded following the key themes of the interview schedule.<br />

Thematic analysis was undertaken manually, in which the efforts<br />

and experiences of each Cancer Council were recorded against<br />

the major service areas.<br />

Staff from The Cancer Councils of the Australian Capital<br />

Territory, Tasmania, Victoria, New South Wales and the Cancer<br />

Foundation of Queensland participated in telephone interviews.<br />

Information was collected from staff at the Cancer Councils of<br />

Western Australia and South Australia through face-to-face<br />

interviews. Before submission of this article for publication, it was<br />

circulated to the CEOs of all participating Cancer Councils, giving<br />

them the opportunity to make additions or corrections, and<br />

appropriately represent their organisation, and suggested<br />

amendments were incorporated.<br />

Findings from the scan<br />

Most interviewees indicated that their organisation had tried to<br />

work with Indigenous communities on cancer-related issues.<br />

Working in partnership with Indigenous organizations was seen as<br />

important, and perhaps more effective than establishing<br />

Indigenous-specific positions within the organisation. However, a<br />

number of respondents noted the difficulty of building and<br />

sustaining relationships with Indigenous health agencies because<br />

they were under-resourced to respond and cancer is not<br />

prioritised among many competing social and health issues. Key<br />

findings related to Indigenous cancer control are summarised in<br />

the Box. Further details are reported according to core functional<br />

areas.<br />

Education and training<br />

Capacity building within the Indigenous health sector was<br />

identified as a priority area, in which respondents believed Cancer<br />

Councils could play an important supportive and advocacy role.<br />

Some success was reported in running training programmes with<br />

Aboriginal Health Workers (AHWs). The most promising example<br />

was initiated by The Queensland Cancer Fund (QCF). Based upon<br />

the priorities identified through consulting Indigenous groups and<br />

other key stakeholders, a cancer care course was developed for<br />

AHWs with assistance from an Indigenous advisory panel in<br />

developing the course content. The five-day programme<br />

introduced various aspects of cancer treatment and care, and<br />

provided site visits to various cancer support services. Overall, it<br />

was felt the course provided a good overview for the AHWs on the<br />

rationale and practical aspects of cancer treatment and insight into<br />

what patients go through during treatment. Scholarships were<br />

provided to 14 health workers from across Queensland to attend<br />

the first course, and this helped with the development of networks<br />

between AHWs and cancer service providers. Indigenous<br />

participants were generally identified through the regional officers<br />

of the QCF and contact with Indigenous communities. The<br />

desirability of oneto- one follow-up and support after training,<br />

utilising regional officers, was emphasised. The QCF has also<br />

trialled a less intensive version of education, for example, by<br />

adapting a mainstream 2- day training programme for community<br />

speakers around prevention and awareness of cancer for delivery<br />

to AHWs in northern Queensland. A small number of volunteer<br />

Indigenous speakers were trained through this programme to<br />

increase cancer awareness in their local communities. Cancer<br />

Councils in some other jurisdictions have also tried to arrange<br />

training programmes with AHWs, although some reported<br />

receiving a low level of interest from the stakeholders. TCCWA<br />

Indigenous Community Controlled Health Organizations in their<br />

areas, have begun planning to incorporate cancer awareness<br />

into AHW training, but not all discussions have yet resulted in<br />

established commitment. The Cancer Council Victoria (TCCV)<br />

has, since 2001, been delivering training on cancer, screening<br />

and cervical cancer to AHWs undertaking the Certificate 4 in<br />

Women’s and Babies’ health which is delivered by the Victorian<br />

Aboriginal Community Controlled Health Organisation. The<br />

Cancer Council New South Wales (TCCNSW) had organised<br />

one-day training workshops for AHWs covering basic<br />

information about cancer biology, prevention, early detection,<br />

treatment and end of life which were jointly delivered by two<br />

Aboriginal consultants. However, the workshops have not been<br />

systematically and regularly conducted. The organisation now<br />

proposed to develop a more sustainable, organised programme<br />

with regional Aboriginal Health Services (AHSs) interested in this<br />

approach. Implementation may occur by extending the 1-day<br />

training workshop to 2 days, and shifting the focus to include<br />

more practical issues related to cancer care. Lack of availability<br />

of Indigenous-specific resources was mentioned as a barrier to<br />

education about cancer. TCCV has supported development of<br />

many Indigenous-friendly resources addressing smoking<br />

cessation and cervical screening. Respondents were also aware<br />

of resources in the process of development by other<br />

organizations such as The Centre for Excellence in Indigenous<br />

Tobacco Control, and felt that specific resources would be<br />

helpful in address Indigenous needs. It was considered<br />

important to develop educational and outreach materials that<br />

included artwork, pictures, role models and/or stories resonating<br />

culturally with the programme’s target population. It was also<br />

stressed that any resources produced must be appropriately<br />

used, because in some instances, good resources remain underutilised<br />

as a result of inadequate promotion, poor distribution or<br />

inadequate staff training in their appropriate use. Although there<br />

was recognition that resources designed in another jurisdiction<br />

were not always suitable and relevant elsewhere, some<br />

respondents noted a lack of capacity within their organizations in<br />

adapting these or developing new resources.<br />

Education of cancer staff about indigenous people<br />

Training and capacity building are not only necessary for AHWs<br />

and community members. Respondents acknowledged the need<br />

for awareness of Indigenous culture, cultural differences and<br />

beliefs to be taught and understood among the mainstream health<br />

service providers. The QCF runs cultural awareness training for<br />

staff twice a year, with training provided by the Department of<br />

Health and delivered by an Indigenous person. The TCCNSW has<br />

been running 2-day workshops on Indigenous culture for about 5<br />

years, and it is mandatory for all staff. TCCV have organised<br />

cultural awareness training in 2001 and 2005, and they now plan<br />

to deliver it annually.<br />

Cancer prevention education<br />

The focus within cancer prevention was strongest in the area of<br />

tobacco control, and primarily focussed on education and support<br />

initiatives. For instance, TCCWA provides support and advice to<br />

Say No To Smokes, the only Aboriginaltargeted tobacco control<br />

project in WA. Working in collaboration with the Say No To<br />

Smokes team, the partners have now submitted a joint funding<br />

proposal for another project, the brainchild of an Aboriginal exsmoker,<br />

to capture and tell in their own words the success stories<br />

of Indigenous people who have stopped smoking. The Australian<br />

Capital Territory Cancer Council in partnership with Winnunga<br />

Nimmitjah runs a smoking cessation programme No More Bunda<br />

for Indigenous people that includes access to free<br />

nicotinereplacement therapy (NRT). This programme was adapted<br />

from a standard cessation programme and has been running for 5<br />

years. TCCV is working in two programme areas — tobacco<br />

control and cervical screening — to take on an Indigenous-specific<br />

focus, and to train and support AHWs. TCCSA supports and plays<br />

partnership roles with the Aboriginal Health Council of South<br />

Australia to deliver a Quit Skills training programme to AHWs.<br />

TCCNSW appointed an Indigenous representative on the planning<br />

committee for a tobacco control conference and provided 12<br />

scholarships for Indigenous people to attend. In reporting on<br />

successful initiatives, respondents often described relatively smallscale<br />

local or regional initiatives where the kernel of the project<br />

came out of a personal or good relationship between a Cancer<br />

Council member and an Indigenous person working in a local<br />

health service or in the community. Such partnerships recognised<br />

that Indigenous Health Services are experienced in working with<br />

Indigenous people, while the Cancer Councils have expertise<br />

around cancer education and supporting people affected by<br />

cancer. Building relationships and reciprocity through sharing<br />

information and skills between organizations was valued by the<br />

informants. A local or regional approach was seen as better able<br />

to support the diverse needs of the Indigenous population within<br />

each state.<br />

Indigenous employment<br />

Involvement of Indigenous people was acknowledged as a crucial<br />

factor in every aspect of cancerrelated service delivery. However,<br />

only one of the Cancer Councils (TCCV) during the project period<br />

reported having an Indigenous staff member. While some Cancer<br />

Councils had experience in recruiting Indigenous staff,<br />

respondents recognised the inherent problems of appointing one<br />

Indigenous position to provide advice across the organisation.<br />

Based upon their observations and experience, respondents<br />

believed that it was difficult to recruit Indigenous staff with the skills<br />

and knowledge to hit the ground running. One respondent<br />

proposed the merits of two or three part-time positions working<br />

together on one project instead of one person across the whole<br />

organisation.<br />

Respondents were aware of the need to provide orientation,<br />

adequate direction and support to Indigenous staff in the same<br />

way as other staff members, but some noted that there had been<br />

difficulties in achieving this in practice. There were risks of<br />

Indigenous staff members feeling isolated, and either not<br />

performing to their ability or suffering burnout. Some respondents<br />

proposed the need to encourage Indigenous employees to<br />

network with other Indigenous people in the health sector if there<br />

were not other Indigenous employees within the organisation. In<br />

the absence of Indigenous staff members, some organizations are<br />

working with Indigenous volunteers and some with non-<br />

Indigenous staff, generally through linking with Indigenous health<br />

service organizations.<br />

Policy and advocacy<br />

The need for Indigenous people to be involved in setting the<br />

agenda and deciding priorities was consistently recognised by the<br />

respondents — as it is in the literature. But respondents also<br />

acknowledged that initiatives would have to fit within the Cancer<br />

Councils’ scope and priorities. Cancer Council staffs are aware of<br />

their reliance upon donors and fundraising events, and were<br />

cautious about undertaking activities that might offend donors or<br />

distract from their mainstream business. A number of the<br />

informants described their organisation as “white middle class”,<br />

not intended as criticism but rather as a statement of where they<br />

were in their historical development. In some jurisdictions,<br />

programmes for culturally and linguistically diverse populations<br />

were also acknowledged as relatively under-developed. The<br />

Cancer Councils generally had not adopted specific Indigenous<br />

action plans, although they had strategic plans that addressed<br />

social determinants of health inequalities, special needs groups<br />

and under-served populations.<br />

Informants generally felt that insufficient time and effort had been<br />

put into Indigenous cancer issues within their organizations to<br />

date. What had been undertaken was described by some as<br />

piecemeal, “just scratching the surface”. There were some<br />

criticisms that efforts had not generally been sustained over time.<br />

For example, one respondent reported that their organisation had<br />

been running programmes like a 1-day workshop on Quit skills to<br />

raise awareness; promoting discussion about priorities and areas<br />

for action to support Indigenous cancer support group; running<br />

projects with young Indigenous women smokers to quit smoking<br />

and so on. However, systematic efforts with follow through have<br />

only recently begun, and are still at an early stage of development.<br />

Some Cancer Councils have established a staff Aboriginal Health<br />

Interest Group. At TCCV a voluntary group with representatives<br />

from most Units was established in 2002 and meets quarterly to<br />

discuss Indigenous issues, provide cultural awareness<br />

opportunities and links with external Aboriginal health agencies.<br />

The group enables increased awareness of Indigenous needs and<br />

information goes back to Units to address.<br />

Cancer support services<br />

Cancer support services provide support across a range of needs<br />

to people during their cancer journey, from counselling newly<br />

diagnosed cancer patients, their families and friends, to providing<br />

emotional and practical support, advice, accommodation and<br />

assistance with palliative care. None of the Cancer Councils<br />

reported that Indigenous people were truly represented in their<br />

client groups. However, TCCSA had supported the establishment<br />

of an independent Indigenous Women’s Cancer Action Group that<br />

provides support to other women with cancer.<br />

Underlying issues for inclusion of Indigenous people in cancer<br />

care and support emerged during the interviews. With regard to<br />

accommodation facilities, some informants reported there had<br />

been tensions related to large families visiting and staying, mess,<br />

dirtiness and noise. It was widely reported that many staff felt ill<br />

equipped to deal with the cultural differences of Indigenous<br />

patients, and some staff were uncomfortable in dealing with<br />

Indigenous families. They did not understand the values and<br />

customs of Indigenous people, while language difficulties further<br />

impeded communication. Often there was no access to<br />

interpreters when the person spoke an Aboriginal language as<br />

their first and usual language. There were also issues with some<br />

Indigenous clients not wanting to be alone in private rooms,<br />

preferring being at floor level rather than bed height, having<br />

different dietary preferences and their preferred foods being<br />

unavailable. Despite challenges in communication, staff often<br />

understood the desire of rural patients to return home to die, but<br />

it generally had required dedicated effort and substantial cost to<br />

achieve this. A number of informants spoke of the importance of<br />

improving the quality of data around Indigenous cancer and<br />

needs. Good information serves as the impetus for setting<br />

priorities and directing resources, giving individuals a rationale for<br />

further work with a minority population. Baseline data for<br />

monitoring progress was seen as vital for people in the field.<br />

Discussion<br />

Cancer Councils in Australia have been highly effective nongovernment<br />

organizations with considerable expertise on all<br />

aspects of cancer control. As a result of their strategic approach,<br />

they are effective advocates around cancer screening, treatment<br />

and support services. As key players in cancer control, they<br />

contribute through education, training, research, advocacy and<br />

cancer support service functions, all of which are necessary<br />

components of achieving improved cancerrelated outcomes for<br />

Indigenous Australians. Cancer Council staff acknowledged the<br />

limitations of their organizations in addressing Indigenous cancer<br />

issues and their own deficiencies in understanding Indigenous<br />

culture and hence the “right” way to do things. But their<br />

willingness and enthusiasm to work with these communities was<br />

apparent in the organisation and participation at the 2004<br />

Indigenous Cancer Control Forum in Darwin, and this was<br />

followed by new initiatives within many of the Cancer Councils.<br />

These initiatives include planning for a state-based Indigenous<br />

Cancer Forum in South Australia (held in September 2006),<br />

training of AHWs, cultural safety training for non-Indigenous<br />

cancer support staff, and working in collaboration with local and<br />

regional Indigenous health organizations.<br />

Limitations identified in the environmental scan which impeded<br />

progress on Indigenous cancer issues were the lack of dedicated<br />

staff time for Indigenous issues, lack of Indigenous staff, limited<br />

commitment of significant resources on a sustained basis, and<br />

lack of Indigenous input into policy and programmes. There were<br />

no Indigenous Board members, and where an Indigenous person<br />

had been appointed as a staff member, often many demands were<br />

made upon them. Some were uncomfortable working in a<br />

mainstream organisation without Indigenous colleagues providing<br />

peer-support. While it was recognised as desirable to have<br />

Indigenous staff members working within the organizations,<br />

respondents appreciated the practical challenges of this, and that<br />

an Indigenous person per se was not a panacea. Most<br />

organizations therefore opted to develop linkages with Indigenous<br />

health organizations, and in some instances such projects had<br />

been sustained over a number of years, with resources committed<br />

over that time period. The linkage approach sometimes proved<br />

frustrating as it often relied upon individual relationships and<br />

required that the Indigenous organisation have both capacity and<br />

commitment to the partnership. Informants recognised the<br />

necessity to build capacity around cancer within the Indigenous<br />

health sector. Considerable activity, not all of which had yet come<br />

to fruition, had been initiated at planning and service levels<br />

Innovations and clinical specialities: oncology<br />

subsequent to the Darwin forum, and the project funded by<br />

TCCWA, of which this scan is a component, exemplifies the<br />

interest in how Indigenous cancer control might be progressed. An<br />

intensive week of training with ongoing opportunities for<br />

networking and relevant professional development seems a<br />

particularly useful approach to increasing Indigenous capacity<br />

around cancer issues. Activities and projects catalysed by small<br />

seed project funding and initiated regionally or locally within<br />

established networks, were often cited as successes. However,<br />

such successes had not generally been translated into sustained<br />

activity or programmes. Participants consistently recognised the<br />

importance of long-term and well planned programmes with<br />

dedicated resources. Practitioners involved in health promotion<br />

with Indigenous clients advocated the use of “nonpreachy”<br />

methods, that is, approaches that appeal to an individual’s<br />

concern for the health and wellbeing of their family and the<br />

community rather than harms to their own health. Thus, messages<br />

around tobacco control might focus initially upon harm reduction<br />

by preventing passive exposure of family members to tobacco<br />

smoke.<br />

Cancer Councils provide support services for people with<br />

cancer that recognise the social, spiritual, emotional, and physical<br />

supports of cancer patients and their family members. However,<br />

most were aware of their own organisational limitations in<br />

understanding and capacity, particularly around Indigenous culture<br />

and values. Although there has been very limited exploration in<br />

Australia of what cancer means to Indigenous Australians, those<br />

interviewed recognised that Western psychosocial and support<br />

models might not be appropriate for Indigenous clients. This deficit<br />

in understanding made service providers feel that they lacked the<br />

knowledge and confidence in supporting Indigenous clients well.<br />

Staffs were keen to better appreciate Indigenous people’s sociocultural<br />

understanding of cancer and to use this knowledge in their<br />

practice in cancer service delivery. Many would welcome<br />

Indigenous cultural awareness training but wanted specific<br />

information around cancer beliefs, not just information about the<br />

historical context of Indigenous health. Although Cancer Councils<br />

have a well developed network of volunteers to help support<br />

people with cancer, training of existing staff and volunteers to<br />

support Indigenous people is needed. It may be helpful to provide<br />

Indigenous mentors for non-Indigenous staff who are<br />

inexperienced in working with Indigenous people. Recruitment<br />

and support for Indigenous volunteers and cancer survivors to<br />

assist in cancer advocacy work is in place in SA and Queensland,<br />

but not in other jurisdictions. One-to-one support services appear<br />

to be underutilised currently, and Indigenous-specific cancer<br />

survivor support resources using testimonials or story-telling may<br />

be helpful. An issue regularly raised within Indigenous cancer<br />

contexts was the use of traditional healers and traditional<br />

medicines, 22 although these issues were generally not mentioned<br />

by the informants interviewed. Support programmes that integrate<br />

cultural components (traditional medicine, selected ceremonies)<br />

may be acceptable and effective means of supporting Indigenous<br />

people to engage in cancer treatment.<br />

There are many similarities between the cancer issues<br />

experienced by Indigenous Australians and those of indigenous<br />

people in other developed countries. It is beyond the scope of this<br />

paper to discuss in detail the experience in cancer control and<br />

support strategies in indigenous populations in countries such as<br />

Canada, New Zealand and the United States. However, the<br />

authors have undertaken a comprehensive literature review of<br />

these populations and key lessons from international experience<br />

are: acknowledgement of past treatment and the impact of<br />

colonisation; acknowledgement of the cultural diversity of<br />

Aboriginal people; recognition of the impact of the structural<br />

causes of inequality; need to enable Indigenous ownership,<br />

participation, partnership and control, with Indigenous<br />

representation at all levels of decision making; and support for<br />

community-based and community-driven interventions. There<br />

have also been efforts to develop culturally appropriate resources<br />

and servicebased programmes, promoting Indigenous healing<br />

approaches concurrently with Western medical treatment. The<br />

reader is recommended to read further about these<br />

approaches 23,28 which were generally Indigenous community-led<br />

and government supported.<br />

While there has been a lack of Australian government leadership<br />

in this area, Cancer Councils can play both an effective practical<br />

and advocacy role at the local, state and national level to ensure<br />

Indigenous issues in cancer control are more effectively<br />

incorporated and heeded. Respondents recognised that this<br />

should be done “hand-in-hand in partnership with Indigenous<br />

communities”, and leadership is needed from The Cancer Council<br />

Australia to ensure that there is steady national progress with<br />

lessons shared across jurisdictions. The need for Cancer Councils<br />

to adopt a respectful approach that invests in learning and<br />

understanding about Indigenous issues, and the reciprocal<br />

benefits that might derive from such partnerships in enhancing<br />

Indigenous cancer control are recognised in the words of one<br />

informant:<br />

“The Darwin Forum was like... the Cancer Council people trying<br />

to learn from Aboriginal people... and if we maintain that theme all<br />

the way through our state-based work or national work, we will do<br />

ok... because we have developed lots of respect in taking that<br />

approach...” ❏<br />

Technology of the 21st Century<br />

Pioneers in Diagnostic Imaging:<br />

Reliability and advanced technology<br />

add value and increase safe diagnosis<br />

ARTICLE BY SHIMADZU EUROPA GMBH<br />

As a pioneer in medical technology since 1896 after recording the first X-ray images in Japan, Shimadzu<br />

develops, manufactures and distributes a broad range of diagnostic systems in almost all areas of clinical<br />

applications – Digital Subtraction Angiography (DSA), cardiovascular systems, digital radiography &<br />

fluoroscopy systems and general radiography equipment.<br />

Directly digitalized X-ray data merge economic with<br />

diagnostic benefits<br />

Safire is one of the most recent developments in X-ray technology<br />

and is the world’s first large-field flat-panel X-ray detector with<br />

direct conversion. X-rays are converted directly into electrical<br />

signals using amorphous selenium – without the need for indirect<br />

light conversion. The result is an outstanding image quality, free of<br />

any influence of scattering with an unparalleled ability for detail<br />

discrimination. With its dynamic detector system which can<br />

acquire 30 images per second, safire offers a wide range of new<br />

and revolutionary applications in radiology, fluoroscopy and<br />

cardiology, such as tomosynthesis, dual-energy subtraction and<br />

slot-radiography. The 23 x 23 cm (9-inch-square) or 43 x 43 cm<br />

(17-inch-square) safire FPD can be used for both still images and<br />

fluoroscopy. Shimadzu’s safire FPDs are integrated in cardio<br />

systems as well as fluoroscopic equipment and bucky rooms.<br />

Introducing the safire direct-conversion FPD to the medical<br />

sector enables digitizing of all X-ray related diagnostic imaging. It<br />

allows faster diagnosis, improved diagnostic capabilities and<br />

accelerated remote medical diagnostics. The current image<br />

amplifier technology, inferior in image quality and dose efficiency,<br />

is expected to soon become obsolete.<br />

C-arm systems, radiography and fluoroscopy as well as<br />

projection radiography<br />

Under the BRANSIST name Shimadzu offers floor- or ceilingmounted<br />

as well as biplane C-arm systems with integrated safire<br />

FPD’s (22 x 22 cm or 43 x 43 cm). In addition to the brilliant image<br />

quality, the BRANSIST system enables real-time operation at a<br />

rotation speed of up to 60° per second.<br />

The SONIALVISION safire X-ray multifunctional instrument can<br />

be used, for instance, to create three-dimensional images of<br />

patients standing upright during prostheses check-ups.<br />

SONIALVISION safire has a low access of 47 cm and a capacity<br />

of up to 318 kg for use in bariatrics.<br />

RADspeed safire, the digital high-end product of the RADspeed<br />

Safire is one of the most<br />

recent developments in<br />

X-ray technology and is<br />

the world’s first largefield<br />

flat-panel X-ray<br />

detector with direct<br />

conversion<br />

family, combines high patient throughput with optimal<br />

convenience for users as well as patients and, at the same time,<br />

delivers brilliant image quality. RADspeed safire acquires clear<br />

images of difficult-to-diagnose findings such as round lesions that<br />

are often obscured by ribs.<br />

Award-winning mobile X-ray technology<br />

In 2009, Shimadzu introduced the MobileArt Evolution series, the<br />

next generation mobile X-ray systems of the award-winning<br />

MobileArt series. This family of systems offers efficiency as well as<br />

user and patient friendliness together with high-quality images.<br />

The premium version can be extended to a fully digital unit<br />

applying FPD.<br />

The new mobile fully digital MobileDaRt Evolution system covers<br />

the entire radiological spectrum. Based on its high-performance<br />

flat-panel detector of 35 x 43 cm, an optimal image quality can be<br />

guaranteed under the most difficult conditions, for example in<br />

trauma and intensive care medicine or on patient wards. With the<br />

Breast Cancer – a review for<br />

African surgeons<br />

Breast Cancer constitutes a major public health issue globally. In Africa, it is the commonest malignancy affecting women<br />

and the incidence rates appear to be rising. While mortality rates are declining in the developed world as a result of early<br />

diagnosis, screening, and improved cancer treatment programmes, the converse is true in the developing world.<br />

Breast cancer and its treatment constitute a great physical, psychosocial and economic challenge in resource limited<br />

societies as found in Africa. The hallmarks of the disease in Africa are clinically advanced disease, lack of adequate<br />

infrastructure for diagnosis, screening and treatment, preponderance of younger pre-menopausal patients.<br />

This Review is meant to provide practical guidance for the surgeon working in the developing world.<br />

There is an international/geographical variation in the<br />

incidence of Breast Cancer. Incidence rates are higher in the<br />

developed countries than in the developing countries and<br />

Japan. Incidence rates are also higher in urban areas than in the<br />

rural areas.<br />

In Africa, Breast Cancer has overtaken cervical cancer as the<br />

commonest malignancy affecting women and the incidence rates<br />

appear to be rising. 3,4 In Nigeria for example, incidence rate has<br />

increased from 13.8–15.3 per 100,000 in the 1980s, to 33.6 per<br />

100,000 in 1992 and 116 per 100,000 in 2001. 5 These increases<br />

in incidence are due to changes in the demography, socioeconomic<br />

parameters, epidemiologic risk factors, better reporting<br />

and awareness of the disease. While mortality rates are declining<br />

in the developed world (Americas, Australia and Western Europe)<br />

as a result of early diagnosis, screening, and improved cancer<br />

treatment programmes, the converse is true in the developing<br />

world as well as in eastern and central Europe. 6-8<br />

Breast cancer and its treatment constitute a great physical,<br />

psychosocial and economic challenge in resource limited societies<br />

as found in Africa. The hallmarks of the disease in Africa are<br />

patients presenting at advanced stage, lack of adequate<br />

mammography screening programmes, preponderance of<br />

younger pre-menopausal patients, and a high morbidity and<br />

mortality. 3,6<br />

This Review is meant to provide practical guidance for the<br />

surgeon working in the developing world. We have relied on the<br />

Chapter on Breast Cancer by Bland et al in Schwartz’s Principles<br />

of Surgery, 8th Edition. 9<br />

Material which is of interest but not immediately applicable has<br />

followed the principles developed in the Breast Health Global<br />

Initiative. 10-12<br />

History<br />

Breast cancer is one of the oldest known forms of malignancies.<br />

The earliest known <strong>document</strong>ation on breast cancer was the<br />

Smith Surgical Papyrus (3000-2500 B.C.) written in Africa (Egypt).<br />

It described 8 cases of tumors or ulcers of the breast that were<br />

treated by cauterization, with a tool called “the fire drill.” The<br />

writing says about the disease, “There is no treatment.” At least<br />

one of the described cases is male. There were few other historical<br />

references to breast cancer until the first century when Celsus<br />

recognized the relevance of operations for early breast cancer.<br />

In the second century, Galen inscribed his classical clinical<br />

observation: “We have often seen in the breast a tumor exactly<br />

resembling the animal the crab. Just as the crab has legs on both<br />

sides of his body, so in this disease the veins extending out from<br />

the unnatural growth take the shape of a crab's legs. We have<br />

often cured this disease in its early stages, but after it has reached<br />

a large size, no one has cured it. In all operations we attempt to<br />

excise the tumor in a circle where it borders on the healthy<br />

tissue.” 13<br />

Halsted and Meyer reported their operations for the local<br />

treatment of breast cancer in 1894. Both Halsted and Meyer<br />

advocated complete dissection of axillary lymph node levels I to III<br />

and removal of pectoral muscle along with the breast. By<br />

demonstrating locoregional control rates after radical resection<br />

and providing the first opportunity for cure, these surgeons<br />

established radical mastectomy as state-of-the-art treatment in<br />

the early part of the 20th century. Later in the century, there was a<br />

transition from the Halsted radical mastectomy to the modified<br />

radical mastectomy (MRM) as the surgical procedure most<br />

frequently used for breast cancer. This procedure maintained the<br />

en bloc dissection of the breast and lymph nodes, but left the<br />

pectoralis major muscle intact.<br />

The recognition in the 1950s that breast cancer was often a<br />

systemic disease at presentation shifted the management of<br />

primary breast cancer away from a purely surgical approach to a<br />

multidisciplinary one that uses systemic therapy, surgery and<br />

radiation. As a result surgery for breast cancer may now be<br />

understanding of the basic science of the disease especially the<br />

genetic and molecular basis of the disease.<br />

Anatomy of the breast<br />

The breast is a modified sweat gland and therefore ectodermal in<br />

origin. It is present in all mammals and becomes particularly<br />

prominent in females as the hallmark of pubertal development. It<br />

lies cushioned in adipose tissue between the subcutaneous fat<br />

layer and the superficial pectoral fascia. It extends from the clavicle<br />

above to the upper border of the rectus sheath below and from the<br />

midline to the posterior axillary line. It overlies the second to the<br />

sixth ribs, the pectoralis major, serratus anterior and the upper part<br />

of the rectus sheath. The area covered is wider than the visible<br />

protuberant breast. An axillary extension of the breast (axillary tail<br />

of Spence) always exists and its size is proportional to the total<br />

volume of the main breast mass. The innervation of the breast is<br />

derived from the anterior branches of the intercostal nerves 2<br />

through 6 with the nipple receiving its innervation from the 4th<br />

intercostal nerve. The major blood supply, in order of importance,<br />

are the internal mammary branches, the lateral thoracic, and the<br />

thoracodorsal perforating vessels from the pectoral branch of the<br />

throacoacrominal branch of the axillary artery, and small<br />

intercostals branches. The venous and lymphatic drainage parallel<br />

the blood supply.<br />

The glandular tissue consists mainly of epithelium, fibrous<br />

stroma, and fat. The breast is organized into roughly 20 lobular<br />

units made up of terminal ducts surrounded by fat and fibrous<br />

tissues and efferent ductules. These terminal ducts coalesce and<br />

drain towards the areola forming the 15-20 ducts of the nipple<br />

areolar complex.<br />

The lymphatic drainage is primarily to the axillary nodes (75%),<br />

divided into three levels by the Pectoralis minor muscle (level I<br />

nodes lie lateral, level II nodes behind and level III nodes medial to<br />

the muscle). Usually, but with some exceptions, lymphatic<br />

drainage is progressive through these levels. Drainage also occurs<br />

to the internal mammary chain of lymph nodes which lie in the<br />

intercostal spaces, the supraclavicular nodes, the opposite breast<br />

and axilla, and to the liver via the rectus abdominis muscle.<br />

Epidemiologic risk factors/etiology<br />

The precise etiology of breast cancer is largely unknown, but<br />

several risk factors have been identified. Table 1 lists the known<br />

risk factors. 14<br />

The risk factors include:<br />

✚ Age: The incidence of breast cancer increases with age and is<br />

rare before the age of 20 years. The breast cancer incidence in<br />

Caucasians is highest at age 50-59, after menopause,<br />

dropping after age 70. In Africa and African-Americans the<br />

peak age incidence is about one decade less, so that the<br />

majority of the patients are pre- menopausal. While numerous<br />

theories have been proposed to explain this difference,<br />

including age at menarche, time of first delivery, parity, sociodemographic<br />

factors, body mass index, and underlying genetic<br />

difference, none are completely satisfactory and more research<br />

is needed in this area. 3-5;15-17<br />

✚ Sex: Breast Cancer is 100 times more common in women<br />

than in men with male breast cancer accounting for


Innovation and clinical specialities: oncology<br />

✚ Previous breast disease: Individuals who have a prior<br />

history of invasive carcinoma or ductal carcinoma in situ have<br />

a 0.5%-1% per year risk of developing a new invasive breast<br />

carcinoma. Women with atypical ductal or lobular hyperplasia<br />

have a four to five times higher risk of developing breast<br />

cancer. Proliferative lesions without atypia, such as moderate<br />

hyperplasia and sclerosing adenosis, are associated with a<br />

slightly increased risk (1.5-2%). Other common nonproliferative<br />

changes such as palpable cysts, fibroadenomas<br />

and duct papillomas are not associated with a significantly<br />

increased risk. 34<br />

✚ Enviromental Exposures: Exposure to ionizing irradiation<br />

increases the risk of developing breast cancer. Excess breast<br />

cancer has been observed in patients given multiple<br />

fluoroscopies, radiotherapy for ankylosing spondylitis, Hodgkin’s<br />

disease, or enlargement of the thymus gland and in survivors of<br />

the atomic bombings, painters of radium watch faces and X-ray<br />

technicians 28 . Environmental exposures to organic chlorines and<br />

other environmental/synthetic estrogens like cosmetics and<br />

phytoestrogens found in food have also been postulated to<br />

increase the risk, but so far there are no conclusive evidence<br />

linking organic chlorines to breast cancer. 31;35;36<br />

Lifestyle risks<br />

Anthropometric indices and physical activity: Height, obesity and<br />

high body mass index are risk factors especially in post<br />

menopausal women. In pre-menopausal women, obesity and high<br />

body mass index has an insignificant but inverse relationship to<br />

breast cancer risk that is reduced by physical activity. 37-39<br />

Diet, alcohol and smoking: alcohol and diets rich in fat especially<br />

saturated fat raises the risk while smoking does not appear to<br />

affect the risk. 40-42<br />

Family history and genetics<br />

A family history of breast cancer increases a woman's risk of<br />

developing the disease. A woman is considered to be at increased<br />

risk if the family member is a first degree relation with early age of<br />

onset (< age 50), if both breasts are involved, or if she has multiple<br />

primary cancers (such as breast and ovarian cancer). Women with<br />

one, two, and three or more first-degree affected relatives have an<br />

increased breast cancer risk when compared with women who do<br />

not have an affected relative (risk ratios 1.8, 2.9 and 3.9,<br />

respectively) 43 Such women are recommended to begin breast<br />

cancer screening at an age 10 years younger than the age at<br />

which the affected relative was diagnosed.<br />

Hereditary breast cancer caused by an underlying inherited<br />

gene mutation accounts for a small proportion (5-10%) of all<br />

breast cancers. The majority is accounted for by 2 germline<br />

mutations BRCA-1 (50%) and BRCA-2 (32%), which are inherited<br />

in an autosomal dominant fashion with varying penetrance. These<br />

tumor suppressor genes are important in the processing of DNA<br />

damage and preservation of genomic integrity. BRCA-1 is located<br />

on chromosome 17q while BRCA-2 is located on chromosome<br />

13q. 44 They are most commonly found in the European Ashkenazi<br />

Jewish population and their descendants, accounting for their<br />

relatively high prevalence in the developed world. In Europe and<br />

North America, BRCA1 is found in 0.1% of the general population,<br />

compared with 20% in the Ashkenazi Jewish population and is<br />

found in 3% of the unselected breast cancer population and in<br />

70% of women with inherited early-onset breast cancer. 9 Up to 50-<br />

87% of women carrying a mutated BRCA1 gene develop breast<br />

cancer during their lifetime. Risks for ovarian and prostate cancers<br />

are also increased in carriers of this mutation. BRCA2 mutations<br />

are identified in 10-20% of families at high risk for breast and<br />

ovarian cancers and in only 2.7% of women with early-onset<br />

breast cancer. The lifetime risk of developing breast cancer in<br />

female carriers is 25-30%. BRCA2 is also a risk factor for male<br />

breast cancer; male carriers have a lifetime risk of 6% for<br />

developing the cancer. BRCA2 mutations are associated with<br />

other types of cancers, such as prostate, pancreatic, fallopian<br />

tube, bladder, non-Hodgkin lymphoma, and basal cell carcinoma.<br />

Risk management strategies for BRCA-1 and BRCA-2 carriers<br />

include:<br />

✚ prophylactic mastectomy and reconstruction;<br />

✚ prophylactic oophorectomy and hormone replacement<br />

therapy;<br />

✚ intensive surveillance for breast and ovarian cancer; and<br />

✚ chemoprevention using Tamoxifen or raloxifene (postmenopausal<br />

women)<br />

In contrast, less is known about genetic mutations as a cause of<br />

breast cancer in the non-Caucasian population. Studies that have<br />

been done of African-Americans, whose genetic history includes<br />

Caucasians, have identified BRCA-1 and -2 mutations but of a<br />

different pattern. 17,45,46 In native Africans, a wide range of BRCA-1<br />

and BRCA-2 mutations and sequence variations have been found<br />

which are unique. This suggests that there may be significant<br />

differences in the genetics of hereditary breast cancer in Africa.<br />

A screening of 206 black South African women with breast<br />

cancer revealed 3 common BRCA1 mutations: 185delAG in exon<br />

2, 4184del4 in exon 11, and 5382insC in exon 2022. A second<br />

study of the coding regions of BRCA1 and BRCA2 genes from 70<br />

Nigerian patients diagnosed with breast cancer before the age of<br />

40 years revealed 2 novel BRCA1 truncating mutations, Q1090X<br />

and 1742insG; four BRCA1 missense variations; one BRCA2<br />

truncating mutation, 3034del4, previously unreported in anyone of<br />

African descent; and 20 nontruncating variants were detected in<br />

BRCA2.45 BRCA1 and BRCA2 mutations and sequence<br />

variations are potentially significant in cases of early-onset breast<br />

cancer within Africa. However, only a small portion of the<br />

mutations were protein truncating, fewer than those observed<br />

among white women 47<br />

Other rare genetic changes that account for predisposition to<br />

breast cancer include Li Fraumeni syndrome (TP53 gene mutation),<br />

Cowdens syndrome, Peutz-Jeghers and Muir-Torre syndromes,<br />

Ataxia Telangiectasia syndrome (caused by the ATM gene). 48-51 New<br />

breast cancer susceptibility genes are being reported and they<br />

include the CHEK2 or CHK2 gene, cytochrome P450 genes<br />

(CYP1A1, CYP2D6, CYP19), glutathione S-transferase family<br />

(GSTM1, GSTP1), alcohol and one-carbon metabolism genes<br />

(ADH1C and MTHFR), DNA repair genes (XRCC1, XRCC3,<br />

ERCC4/XPF) and genes encoding cell signaling molecules (PR, ER,<br />

TNFalpha or HSP70). All these factors contribute to a better<br />

understanding of breast cancer risk but the degree of penetrance<br />

of these genes are far less than the BRCA1 and BRCA2 genes 43,51<br />

Risk assessment<br />

Several statistical models are currently in use in North America to<br />

92 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: oncology<br />

predict the risk of breast cancer, based on the above risk factors<br />

identified in the American Caucasian population. The universal<br />

applicability of these models can not, however be taken for<br />

granted as the data on which they rely on were generated from<br />

predominantly American Caucasian population and have not been<br />

tested for African women 43,52,53<br />

The most prominent statistical models are the Gail and the<br />

Claus models. Gail and colleagues developed the most frequently<br />

used model, which incorporates age at menarche, the number of<br />

breast biopsies, age at first live birth, and the number of firstdegree<br />

relatives with breast cancer. It predicts the cumulative risk<br />

of breast cancer according to decade of life. To calculate breast<br />

cancer risk with the Gail model, a woman's risk factors are<br />

translated into an overall risk score by multiplying her relative risks<br />

from several categories. This risk score is then compared to an<br />

adjusted population risk of breast cancer to determine a woman’s<br />

individual risk. A software programme incorporating the Gail<br />

model is available from the National Cancer Institute at<br />

http://bcra.nci.nih.gov/brc.<br />

Claus and colleagues, using data from the Cancer and Steroid<br />

Hormone Study, a case-control study of breast cancer, developed<br />

the other frequently used risk-assessment model, which is based<br />

on assumptions about the prevalence of high-penetrance breast<br />

cancer susceptibility genes. Compared with the Gail model, the<br />

Claus model incorporates more information about family history,<br />

but excludes other risk factors. The Claus model provides<br />

individual estimates of breast cancer risk according to decade of<br />

life based on knowledge of first- and second-degree relatives with<br />

breast cancer and their age at diagnosis. Risk factors that are<br />

less-consistently associated with breast cancer (diet, use of oral<br />

contraceptives, lactation), or are rare in the general population<br />

(radiation exposure), are not included in either the Gail or Claus<br />

risk-assessment models. 54<br />

Pathology<br />

Breast cancers are derived from the epithelial cells that line the<br />

terminal duct lobular unit. Cancer cells that remain within the<br />

basement membrane of the elements of the terminal duct lobular<br />

unit and the draining duct are classified as in situ or non-invasive.<br />

An invasive breast cancer is one in which there is dissemination of<br />

cancer cells outside the basement membrane of the ducts and<br />

lobules into the surrounding adjacent normal tissue.<br />

TNM staging for Breast Cancer (AJCC classification (6th edition or<br />

revision) 55 , which incorporates both clinical information and<br />

changes related to the growing use of new technology (e.g.,<br />

sentinel lymph node biopsy, immunohistochemical staining,<br />

reverse transcriptase-polymerase chain reaction). Patients with<br />

bilateral or multicentric breast cancer are staged according to the<br />

size of the largest tumor.<br />

Diagnosis<br />

Examination<br />

Early breast cancer causes no symptoms and is usually painless.<br />

The commonest symptom is a painless lump in the breast.<br />

Examination of the breast should be done in such a way to show<br />

respect for the privacy and comfort of the patient. A systematic<br />

approach to breast examination is important. Initial examination<br />

should start with the patient in an upright position with careful<br />

visual inspection of masses, skin and nipple changes, and<br />

asymmetries. Palpation should be done to include all the breast<br />

quadrants, the nipple-areola complex, the axillary tail and the<br />

axilla. Simple maneuvers like stretching the arms high above the<br />

head, tensing the pectoralis muscles may help accentuate<br />

asymmetries and dimpling.<br />

Other less frequent presenting signs and symptoms of breast<br />

cancer include (1) breast enlargement or asymmetry; (2) nipple<br />

changes, retraction, or discharge, including Paget’s disease; (3)<br />

ulceration or erythema of the skin of the breast including<br />

inflammatory carcinoma; (4) an axillary mass; and (5) systemic<br />

symptoms such as fatigue, cough, ascites or new musculoskeletal<br />

discomfort.<br />

Imaging<br />

Mammography, Ductography, Ultrasonography, MRI are imaging<br />

techniques useful in the screening and diagnosis of breast cancer.<br />

Mammography is the most useful test to differentiate between<br />

benign and malignant lesions and is the one that is recommended<br />

for breast cancer screening. Specific mammography features that<br />

suggest a diagnosis of a breast cancer include a solid mass with<br />

or without stellate features, asymmetric thickening of breast<br />

tissues, and clustered microcalcifications Mammography may also<br />

be used to guide interventional procedures, including needle<br />

localization and needle biopsy.<br />

Xeromammography techniques are identical to those of<br />

mammography with the exception that the image is recorded on a<br />

xerography plate, which provides a positive rather than a negative<br />

image Details of the entire breast and the soft tissues of the chest<br />

wall may be recorded with one exposure.<br />

Ductography and ductoscopy<br />

Mammary ductoscopy (MD) is a newly developed endoscopic<br />

technique that allows direct visualization and biopsy examination<br />

of the mammary ductal epithelium where most cancers originate.<br />

When combined with ductal lavage and cytology , it may reveal<br />

early carcinoma. 56-59 The primary indication for ductography is<br />

nipple discharge, particularly when the fluid contains blood.<br />

Radiopaque contrast media is injected into one or more of the<br />

major ducts and mammography is performed. Intraductal<br />

papillomas are seen as small filling defects surrounded by contrast<br />

media. Cancers may appear as irregular masses or as multiple<br />

intraluminal filling defects.<br />

Ultrasonography is an important method of resolving equivocal<br />

mammography findings, defining cystic masses, and demonstrating<br />

the echogenic qualities of specific solid abnormalities.<br />

Ultrasonography is used to guide fine-needle aspiration biopsy,<br />

core-needle biopsy, and needle localization of breast lesions. It is<br />

highly reproducible and has a high patient acceptance rate, but<br />

does not reliably detect lesions that are 1 cm or less in diameter<br />

Magnetic Resonance Imaging is a non invasive, non radiating<br />

imaging technique. In the process of evaluating MRI as a means<br />

of characterizing mammography abnormalities, additional breast<br />

lesions have been detected. However, in the circumstance of both<br />

a negative mammogram and a negative physical examination, the<br />

probability of a breast cancer being diagnosed by MRI is extremely<br />

low. There is current interest in using MRI to screen the breasts of<br />

high-risk women and of women with a newly diagnosed breast<br />

cancer. In the first case, women with a strong family history of<br />

breast cancer or who carry known genetic mutations require<br />

screening at an early age, but mammography evaluation is limited<br />

because of the increased breast density in younger women. In the<br />

second case, a study of MRI of the contralateral breast in women<br />

with a known breast cancer showed a contralateral breast cancer<br />

in 5.7% of these women. 62-64<br />

Plain X-rays and Bone Scan are useful in the detection and<br />

diagnosis of metastasis especially to the bones.<br />

MRI, PET, CT Scans and bone scans are not readily available in<br />

most centers in the developing world, and when available, the cost<br />

of these procedures makes them virtually unrealistic for many of<br />

the patients. Ultrasonography and X-rays are however readily<br />

available and many patients will end up with these minimal<br />

investigations and the standard history and physical examination.<br />

Biopsy<br />

Pathologic diagnosis of a breast lesion can be achieved using a<br />

number of biopsy techniques. With a larger biopsy sample, greater<br />

accuracy and more information are obtained, but this is at the<br />

expense of increased invasiveness. Ideally, needle biopsies should<br />

be performed after imaging to help prevent distortions of imaging<br />

due to hematoma. The various needle biopsy techniques can be<br />

divided into two groups:<br />

✚ 1. Fine needle aspiration will provide cytology which will allow<br />

a diagnosis of malignant cells but will not differentiate between<br />

in situ or invasive disease.<br />

✚ 2. Tissue biopsy for histology which include Tru cut biopsy,<br />

Biopty cut, Mammotome. These relatively larger tissue samples<br />

will allow the diagnosis of invasive versus in situ cancer.<br />

Table 4 compares the accuracy of needle biopsy techniques.<br />

Open Biopsy (Excision or Incision biopsy) The ultimate diagnostic<br />

biopsy is open biopsy of a lesion, normally performed under<br />

general or local anesthetic. Open excisional biopsy should be<br />

reserved for lesions for which some doubt remains regarding<br />

diagnosis after less invasive assessment or for benign lesions that<br />

the patient wants removed. A wide clearance of the lesion is usually<br />

not the goal in diagnostic biopsies, thus avoiding unnecessary<br />

distortion of the breast. It is also useful for excision of<br />

mammographic lesions when percutaneous biopsy has failed or is<br />

equivocal. Where frozen section is available, open excisional biopsy<br />

may be performed at the same time the as definitive breast cancer<br />

surgery. Incisional biopsy is used only in cases where the lesion is<br />

very large and a percutaneous biopsy has been unsuccessful.<br />

Screening<br />

Annual screening mammography has been demonstrated to<br />

reduce breast cancer mortality among women older than 50 years<br />

by 20 –39%. The benefit in younger women is not yet established.<br />

For Caucasian women aged 40–49, the results of RCTs are<br />

consistent in showing no benefits at 5–7 years after entry, a<br />

marginal benefit at 10–12 years, and unknown benefit thereafter.<br />

This is primarily because when used as a screening tool, the<br />

detection rate per screened individual is lower because of denser<br />

breasts and an overall lower incidence. The controversy over the<br />

effectiveness of screening mammography among younger women<br />

(i.e., 40–49 years) has led to varying recommendations about its<br />

use for this age group. In patients with high risk factors a yearly<br />

mammography assessment from the age of 40 years is<br />

advisable. 65-67 Considering the younger demographic pattern of<br />

Breast Cancer in Africa, it is not clear what role screening<br />

mammography should have in Africa.<br />

Other methods of early breast cancer screening like Self Breast<br />

Examination and Clinical Breast Examination have not been<br />

demonstrated to improve mortality in patients; rather SBE has<br />

resulted in more breast biopsies due to false positive results, more<br />

physician visits and apprehension in patients 68 . It is pertinent to<br />

state that most of the studies that evaluated the role of SBE and<br />

CBE have been done in developed societies where cancers are<br />

small at diagnosis and this may not be relevant in Africa where the<br />

majority of patients present late. Incorporation of Breast<br />

Awareness programmes and health education into the Primary<br />

Health Care of African countries may very well be a useful option<br />

to allow for a diagnosis at an earlier stage. Cultural attitudes play<br />

important roles in the acceptance of screening programmes. 69<br />

Treatment<br />

Treatment strategy will depend on the stage of the disease.<br />

In situ breast cancer (DCIS and LCIS)<br />

LCIS: Observation alone with or without tamoxifen is the preferred<br />

option for women diagnosed with LCIS because their risk of<br />

developing invasive carcinoma is relatively low (approximately 21%<br />

over 15 years) and is equal in both breast.. 70 Follow-up of patients<br />

with LCIS includes physical examinations every 6 to 12 months for<br />

5 years and then annually. Annual diagnostic mammography is<br />

recommended in patients being followed with clinical observation.<br />

DCIS: Treatment options for DCIS are mastectomy, breastconserving<br />

surgery (BCS) plus radiotherapy or BCS alone. The<br />

goal of treatment for DCIS is to reduce local recurrence, because<br />

50% of the time that DCIS recurs it recurs as an invasive cancer.<br />

Factors that may modify treatment are:<br />

✚ the grade of the lesion, with higher-grade lesions more likely to<br />

recur in a short time;<br />

✚ the youth of the patient, with many more years at risk for<br />

recurrence and<br />

✚ the size of the lesion.<br />

For years the traditional surgical management of DCIS was<br />

mastectomy, with or without axillary dissection. Breast<br />

conservation technique and irradiation is now a preferred<br />

alternative where local breast radiation is available. Only small, low<br />

grade DCIS that has been excised with a large margin may be<br />

considered for BCS alone. Axillary lymph node staging is<br />

discouraged in women with apparent pure DCIS. However, a small<br />

proportion of patients with apparent pure DCIS will be found to<br />

have invasive cancer at the time of their definitive surgical<br />

procedure which will require a further axillary dissection. 71 Addition<br />

of Tamoxifen reduces the risk of developing contralateral breast<br />

cancer. 72,73 . Follow-up of women with DCIS includes a physical<br />

examination every 6 months for 5 years and then annually, as well<br />

as yearly diagnostic mammography.<br />

Early breast cancer (stages I and II or T1-3N0-1 M0):<br />

Staging for metastatic disease is standard for most patients<br />

diagnosed with early breast cancer and include a chest X-ray,<br />

bone scan and ultrasound of the abdomen. If negative, treatment<br />

intent is curative, and involve modalities that fight the cancer<br />

locally (surgery and radiation) and systemically (chemotherapy and<br />

endocrine therapy).<br />

Loco-regional treatment:<br />

Local treatment requires the treatment of the entire breast and the<br />

axillary lymph nodes with surgery, radiation, or a combination of<br />

both. Surgery can be breast conservation therapy (BCT) and<br />

axillary staging (SLNB or axillary dissection) or simple or total<br />

mastectomy with axillary staging (modified radical mastectomy).<br />

The surgical procedure for the excision of the breast in BCT<br />

goes by several names (Partial mastectomy, tylectomy, segmental<br />

resection, quadrantectomy or lumpectomy).<br />

The goal of breast-conserving surgery is to minimize the risk of<br />

local recurrence while leaving the patient with a cosmetically<br />

acceptable breast. The selection of BCT versus mastectomy<br />

depends on the size of the tumor relative to the rest of the breast<br />

96 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: oncology<br />

and the availability of radiation. BCT and breast radiation together<br />

offers equivalent survival to total mastectomy provided the BCT<br />

removes the entire tumor with negative margins. Generally a tumor<br />

less that 1/4 of the breast is amenable to BCT; anything much<br />

larger will result in significant breast distortion after surgery and<br />

radiation. The procedure can be done safely with local anesthesia<br />

and sedation unless axillary dissection is part of the procedure. A<br />

curvilinear incision lying parallel to the nipple-areola complex is<br />

made in the skin overlying the breast cancer. Radial scars are<br />

avoided because of poor cosmetic results. Skin encompassing any<br />

prior biopsy site is excised, but skin excision is not otherwise<br />

necessary. The breast cancer is removed with an envelope of<br />

normal-appearing breast tissue. Meticulous hemostasis is<br />

important because a large hematoma distorts the appearance of<br />

the breast and makes re-excision and follow-up more difficult.<br />

The excised specimen is orientated for the pathologist using<br />

sutures, clips, or dyes. Additional margins (superior, inferior,<br />

medial, lateral, superficial, and deep) can be taken from the<br />

surgical bed to confirm complete excision of the tumor. These six<br />

margins are marked with titanic clips as this may help the<br />

Radiotherapist in planning the boost. In addition, it helps the<br />

surgeon to do an adequate re-resection if the margins are not free<br />

of cancer cells at definitive paraffin-embedded histology sections.<br />

Attempts to re-approximate the cavity in the breast should be<br />

avoided, because this will usually distort the breast contour, which<br />

may not be apparent when the patient is supine on the operating<br />

table. Similarly, drains are not used. Allowing the cavity to fill with<br />

serum and fibrin maintains contour in the early postoperative<br />

period and helps to avoid deformity. The procedure is completed<br />

with two-layer closure of the deep dermis and the subcuticular<br />

layer, and a light dressing is used.<br />

There is no firm consensus on the extent of the excision or<br />

margins required. The main benefit of BCT is preservation of body<br />

image for the woman, which greatly improves her quality of life.<br />

Several randomized controlled trials have shown that BCT and<br />

radiation has a similar survival advantage as mastectomy as there<br />

were no significant differences in the two groups in disease-free<br />

survival, distant-disease-free survival, or overall survival and even<br />

in loco regional control. 74-80<br />

Contraindications to breast conservation therapy (BCT) can be<br />

divided into absolute or relative. Absolute contraindications<br />

include lack of mammography facilities to ensure all tumors have<br />

been removed, adequate pathology facilities to ensure tumor- free<br />

resection margins and/or lack of radiotherapy facilities. 10,11 Other<br />

contraindications include pregnancy (first or second trimester<br />

because of the risk of radiotherapy to the fetus), patient’s<br />

preference, diffuse suspicious calcifications, inflammatory breast<br />

carcinoma, previous radiation to the region, and inability to achieve<br />

negative margins particularly with extensive intraductal carcinoma<br />

(EIC). Relative contraindications also include two or more gross<br />

tumors (multicentric disease) in different quadrants, tumor greater<br />

than 5 cm initially or after neoadjuvant chemotherapy, large tumorbreast<br />

ratio for cosmesis, and collagen vascular disease. 74<br />

In Africa, many of the factors above make the practice of BCT<br />

difficult and these include lack of adequate diagnostic oncology<br />

services like mammography and surgical pathology, lack of<br />

adequate therapeutic oncology services like radiotherapy,<br />

advanced stage disease and poor follow up culture. 5 Thus the<br />

majority of the patients with early breast cancer in Africa should<br />

still undergo total mastectomy and axillary clearance.<br />

In a total or simple mastectomy, the patient is placed in the<br />

supine position with the ipsilateral arm extended horizontally.<br />

General anesthesia is used. The incision is in the form of an ellipse<br />

is designed to include the skin overlying the tumor or biopsy scar<br />

and the nipple–areola complex. Superior and inferior skin flaps are<br />

then raised. The plane between the subcutaneous tissue and<br />

breast tissue is not always obvious and is most easily identified at<br />

the medial superior flap; it is therefore easiest to begin here. The<br />

skin flaps must be thin, to ensure that all the breast tissue is<br />

removed, and yet enough subcutaneous fat to ensure adequate<br />

blood supply to the skin. Superiorly the dissection must include<br />

the tail of Spence laterally. Inferiorly, the dissection ends at the<br />

inframammary fold. The entire breast, the skin ellipse, nippleareola<br />

complex are then dissected off the pectoralis fascia. The<br />

procedure is completed with an en bloc excision of the axillary<br />

lymph nodes level I and II (see description below). The<br />

mastectomy site and axillary nodal basin are then irrigated with<br />

saline solution, and meticulous hemostasis is achieved. The<br />

wound is closed with a closed suction drainage bottle fixed to a<br />

catheter brought out through a separate stab incision.<br />

Modified radical mastectomy can be done alone or in<br />

association with breast reconstruction. Reconstruction, using<br />

implants or myocutaneous flaps, provides many women with an<br />

enhanced body image and self-esteem, and better psychosocial<br />

adjustment, but it does not impact on the probability of disease<br />

recurrence or survival. 81,82 One method becoming widely used is<br />

the skin-sparing mastectomy (SSM) that conserves an extensive<br />

section of skin, as well as the more recent skin and nipple-sparing<br />

mastectomy that preserves the nipple-areolar complex. 83-85 SSM is<br />

clearly contraindicated in patients with direct involvement of the<br />

skin by the underlying tumor. Nicotine, previous radiotherapy,<br />

diabetes and obesity increase the risk of skin envelope ischemia,<br />

skin necrosis and infection.<br />

However, the additional cost of reconstruction is an issue<br />

especially in resource poor countries.<br />

Treatment of the axilla<br />

Axillary lymph node dissection (ALND)<br />

The status of axillary and internal mammary lymph nodes is the<br />

most significant prognostic factor for survival in patients with<br />

breast cancer. In breast cancer, the status of axillary and internal<br />

mammary lymph nodes is the most significant prognostic factor<br />

for survival. The axillary nodal basin has been the main target in<br />

lymphatic staging in breast cancer because over 75% of the<br />

lymphatic flow from the breast is directed to the ipsilateral axilla.<br />

Axillary clearance (ALND) has been the gold standard in axillary<br />

staging in breast cancer, providing valuable information about the<br />

planning of adjuvant therapy, prognosis and an excellent regional<br />

disease control as well. Removal of 10 or more nodes as assessed<br />

by the pathologist provides accurate information about the axillary<br />

nodal status of the patient.<br />

The most accepted surgical axillary clearance procedure is a<br />

level I and II axillary dissection, detecting 98.5% of cases with<br />

positive axillary nodes. 86 Either at the time of mastectomy, or<br />

through a separate incision (if BCT), the lateral border of pectoralis<br />

major muscle is identified. The clavipectoral fascia, extending<br />

laterally from the edge of this muscle, is divided parallel to the<br />

edge of the muscle to allow entry into the axilla. The superior<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 97


Innovation and clinical specialities: oncology<br />

border of the dissection is the lower border of the axillary vein;<br />

dissection above the vein runs the risk of damage to the brachial<br />

plexus. The nerves to latissimus dorsi (thoracodorsal) and to<br />

serratus (long thoracic) are identified and are the posterior border<br />

of the dissection. The lateral border is the floor of the axilla,<br />

consisting of skin and subcutaneous tissue. Retraction of the<br />

pectoralis minor muscle medially allows for the removal of level II<br />

nodes. All the fatty tissue within these borders is removed. The<br />

sensory intercostal brachial nerve runs through the axilla and may<br />

or may not be preserved.<br />

Sentinel node biopsy<br />

Although long considered the standard management of the axilla for<br />

breast cancer, ANLD is associated with significant arm morbidity<br />

(20-25% risk of lymphedema) and risk of damage to the axillary vein,<br />

nerve to the latissimus dorsi and serratus anterior and hypoesthesia<br />

of the arm and the thorax. For these reasons, other less invasive but<br />

accurate methods have been sought for axillary staging in breast<br />

cancer, especially in the developed world, where three-quarters of<br />

patients present with early node negative disease. Clinical<br />

examination of the axilla and available diagnostic imaging<br />

techniques like US, CT and PDG-PET are manifestly inaccurate for<br />

axillary staging.<br />

Less invasive than ALND, sentinel lymph node biopsy (SLNB) is<br />

now accepted as an alternative to routine ALND for the detection<br />

of occult lymph node metastases in patients with clinically nodenegative<br />

breast cancer. 87,88 SNLD is based on the observation that<br />

specific areas of the breast drain by way of afferent lymphatics to<br />

a specific ‘sentinel’ node. This node can be detected by injecting<br />

vital blue dye (isosulfan blue dye, methylene blue or patent blue V<br />

dye) or a radioactive suspension (Tc99m radioisotope labeled<br />

colloids). The route of injections include intra parenchymal (peritumorally),<br />

intradermal or subareolar. 88,89 . The use of vital dye is<br />

resource efficient (cheaper and less time consuming) and safer,<br />

but may miss non axillary sites and also carries the risk of<br />

anaphylactic reactions while radioactive agents are more<br />

expensive, carries the risk of exposure to staff, and requires that<br />

the hospital have a nuclear medicine department.<br />

There are five principal aims for the excision and<br />

histopathological analysis of the SN:<br />

✚ minimally invasive assessment of the nodal status;<br />

✚ selection of patients with positive SNs for elective lymph node<br />

dissection (ELND) or adjuvant therapy;<br />

✚ prevention of lymph node dissection and associated morbidity<br />

in SN negative patients;<br />

✚ detection of aberrant or alternative lymphatic drainage;<br />

✚ improvement of sensitivity of histopathological detection of<br />

lymph node metastasis. 90<br />

Further surgery of the axillary nodes now depends on the results<br />

of the sentinel lymph-node biopsy – if negative, ALND is avoided.<br />

While SLNB is becoming widely used in the developed world as a<br />

method to assess the axilla, ALND remains the recommended<br />

management for treatment in any hospital that does not have<br />

access to a nuclear medicine department or a dedicated breast<br />

pathologist able to use specialized immunohistochemistry markers.<br />

Radiotherapy in early breast cancer<br />

The aim of radiotherapy to the whole breast after BCT is to<br />

establish local control. Numerous studies have shown reductions<br />

in local recurrences from 12-35% to 2-10% at 5-10 years. This<br />

compares to local recurrence rates after mastectomy of 5%.(91) In<br />

most developed countries, the current standard of care for<br />

patients with early-stage breast cancer consists of breastconserving<br />

surgery, followed by 5–6 weeks’ postoperative<br />

radiotherapy used on the whole breast. Probabilities of adequate<br />

local control rates and good cosmetic results are high with the use<br />

of conventional fractionation. Patients who cannot receive<br />

radiation are treated with mastectomy. Some recent papers<br />

suggest a small survival advantage which was rather offset by the<br />

long term toxicity from radiotherapy resulting in deaths from<br />

vascular and cardiac injuries. 92<br />

Some data support the effectiveness of an additional dose<br />

applied to the tumor bed (i.e., boost irradiation) to reduce local<br />

recurrence. However, delivery of the boosting dose raises the rate<br />

of morbidity, which reduces cosmetic outcome.<br />

Recent advances in radiotherapy includes partial breast<br />

irradiation using various techniques such as such as low or highdose<br />

rate brachytherapy (interstitially or with an intracavitary<br />

balloon), conformal external-beam irradiation (including intensity<br />

modulated radiotherapy), and intraoperative radiotherapy (Electron<br />

Intra Operative Therapy-ELIOT). 93,94<br />

Most reports of partial breast irradiation have provided results<br />

much the same as those achieved with conventional external<br />

beam, even though some caution is needed until the safety and<br />

efficacy of such irradiation have been shown in appropriate<br />

patients and analysis of long-term treatment outcomes. 95-97<br />

Systemic treatment<br />

More than half the women with operable breast cancer who<br />

receive only locoregional treatment die from metastatic disease.<br />

This indicates that breast cancer is a systemic disease and that<br />

the micrometastatic process can occur early even independently<br />

from lymphatic spread. 76,98 The way to improve survival is to give<br />

these women systemic medical treatment, including endocrine<br />

therapy, chemotherapy, or targeted therapy with trastuzumab<br />

along with surgery/radiotherapy.<br />

Systemic treatment may be given after (adjuvant) or before<br />

(neoadjuvant, primary, or preoperative) locoregional treatment.<br />

Adjuvant treatment has been shown to be effective in randomized<br />

clinical trials, whereas the evaluation of neoadjuvant systemic<br />

therapy is ongoing.<br />

It is important to realize, especially in the African context, that any<br />

systemic therapy including hormonal therapies, will at least<br />

temporarily interrupt child bearing. The current recommendations of<br />

at least 5 years of Tamoxifen after diagnosis will significantly impact<br />

on the ability of a woman to bear many children. Chemotherapy will<br />

cause most women to stop menstruating and permanent premature<br />

menopause is common. These recommendations listed below,<br />

based on the culture of the developed world, may not be<br />

acceptable or applicable to African women.<br />

The choice of systemic adjuvant therapy in early breast cancer<br />

will depend on the following factors; estrogen (ER)/progesterone<br />

(PR) receptor status, menopausal status and over-expression of<br />

HER2. It will also depend significantly on the risk of recurrence and<br />

therefore the potential benefit of the treatment. Any systemic<br />

therapy carries with it a risk of toxicity, and can be quite expensive.<br />

A woman at high risk of recurrence will benefit significantly from<br />

98 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: oncology<br />

Figure 1: Advanced breast cancer<br />

treatment while for a woman at low risk the benefit will be small yet<br />

she will be exposed to the same toxicity. For example, a 20%<br />

reduction with chemotherapy for a patient with a baseline 50% risk<br />

of recurrence will result in an absolute reduction to 10% (from 50%<br />

to 40%) where as a woman with a 10% recurrence risk reduces<br />

her risk of recurrence to 8%, only a 2 % absolute reduction. Some<br />

women would not choose chemotherapy for a 2% risk reduction<br />

and others might. The decision to take systemic therapy therefore<br />

is therefore very much dependent on the woman and her<br />

understanding of these risks. 99<br />

Adjuvant endocrine therapy is effective in ER and/ or PR positive<br />

tumors. The most commonly used endocrine therapy is the<br />

Selective Estrogen Receptor Modulator (SERM) Tamoxifen, used<br />

in premenopausal women. Other SERM agents like Toremifene<br />

and Raloxifene are equally effective. There is strong evidence to<br />

support the superiority of a 5 year Tamoxifen therapy over shorter<br />

durations. Tamoxifen in addition helps to maintain bone mineral<br />

density in post menopausal women and reduces the risk of<br />

developing cancer in the contralateral breast. The side effects of<br />

Tamoxifen include hot flashes, risk of thrombo-embolic disease,<br />

endometrial carcinoma and cataracts.<br />

For post-menopausal women, third generation selective<br />

aromatase inhibitors have been shown in recent trials to be more<br />

effective than Tamoxifen and have become the standard of care.<br />

Examples include non steroidal type (anastrozole and letrozole)<br />

and the steroidal type exemestane. Patients using aromatase<br />

inhibitors have less gynecological symptoms such as endometrial<br />

cancer, vaginal bleeding, and vaginal discharges. Fewer<br />

cerebrovascular events and venous thromboembolic events were<br />

also observed with patients receiving aromatase inhibitors.<br />

However, musculoskeletal effects (arthritis, arthralgia, and/or<br />

myalgia) and bone toxicity (bone fractures) are associated with<br />

aromatase inhibitors.<br />

The combination of endocrine therapy and cytotoxic<br />

chemotherapy provides benefits greater than the benefits from<br />

either therapy alone. They are therefore usually offered sequentially,<br />

with chemotherapy given right after surgery, local radiation therapy<br />

is then given, and endocrine therapy commenced. Premenopausal<br />

women are given Tamoxifen for five years. The optimal duration of<br />

the aromatase inhibitors has not yet been determined and<br />

postmenopausal women remain on them indefinitely.<br />

Ovarian ablation (e.g., surgical oophorectomy or radiation<br />

ablation) or suppression (e.g., use of the gonadotropin- releasing<br />

hormone or luteinizing hormone-releasing hormone analogues) is<br />

another effective way to reduce estrogen in premenopausal<br />

women. It can be used as an adjuvant treatment alone or to<br />

induce menopause in very high risk premenopausal women to<br />

allow the use of adjuvant aromatase inhibitors.<br />

Chemotherapy<br />

Chemotherapy has been shown to substantially improve the longterm,<br />

relapse-free, and overall survival in both premenopausal and<br />

postmenopausal women up to age 70 years with lymph nodepositive<br />

and lymph node-negative disease irrespective of the<br />

hormone receptor status.<br />

The administration of polychemotherapy (two or more agents) is<br />

superior to the administration of single agents. Four to six courses<br />

of treatment (3–6 months) appear to provide optimal benefit, with<br />

the administration of additional courses adding to toxicity without<br />

substantially improving overall outcome. Popular regimes include<br />

CMF (cyclophosphamide, methotrexate,fluorouracil), CAF, AC,<br />

FEC. Anthracycline based adjuvant therapy (with doxorubicin or<br />

epirubicin) result in a small (4-5%) but statistically significant<br />

improvement in survival compared with non-anthracyclinecontaining<br />

regimens. 100 .<br />

Trials using accelerated or dose dense chemotherapy (two<br />

weekly interval instead of the standard three weeks) with<br />

granulocyte colony stimulating factor (GCSF) support to overcome<br />

the risk of neutropenic sepsis has been demonstrated to improve<br />

both disease free survival and overall survival with fewer<br />

neutropenic crises.<br />

Trials using high dose chemotherapy with haemopoietic stem<br />

cell rescue on the other hand showed high morbidity and no<br />

benefit from this approach.<br />

Around 20% of breast cancers over express HER2, and this is<br />

associated with an adverse prognosis. Trastuzumab is a<br />

humanised monoclonal antibody directed against the external<br />

domain of the receptor with clinical activity as a single agent<br />

inpatients whose cancers over express HER2.<br />

Trastuzumab in combination with Taxanes and other drugs have<br />

shown considerable improvement in metastastic breast cancer. Its<br />

role in the adjuvant setting in early breast cancer has been so<br />

successful in HER2 positive breast cancer showing significant DFS<br />

and OS. Unfortunately, the cost implication is a drawback to its<br />

use in countries with limited resources.<br />

Bisphosphonates are drugs that inhibit osteoclast mediated<br />

bone resorption induced by tumors. Some adjuvant trials indicate<br />

that two years of oral clodronate reduces the incidence of bone<br />

metastases. One trial showed a small, but significant,<br />

improvement in overall survival. Further trials are underway with<br />

clodronate and the newer, more potent bisphosphonate<br />

zoledronate to define their long term effectiveness.<br />

They are very useful in patients taking Aromatase inhibitors<br />

because of the risk of bone loss and fractures.<br />

of all breast cancers in countries with limited resources and has a<br />

poor prognosis 12 . Locally advanced tumors include tumours that<br />

present with palpable lymph node metastases, ulcerations, tumors<br />

greater than 5 cm etc.<br />

A subtype of LABC that deserves some further discussion is<br />

Inflammatory Breast Cancer (IBC). Inflammatory breast cancer is a<br />

rare but aggressive subtype of breast cancer, which historically<br />

was considered uniformly fatal. Clinically, inflammatory breast<br />

cancer is characterized by the rapid onset of breast warmth,<br />

erythema, and edema (peau d’orange) often without a welldefined<br />

mass.<br />

Along with extensive breast involvement, women with<br />

inflammatory carcinoma often have early involvement of the axillary<br />

lymph nodes. In general, women with inflammatory breast cancer<br />

present at a younger age are more likely to have metastatic<br />

disease at diagnosis, and have shorter survival than women with<br />

non-inflammatory breast cancer. 101-103 The management of LABC<br />

requires a combined modality treatment approach involving<br />

surgery, radiotherapy and systemic therapy.<br />

Radiotherapy in LABC<br />

Radiotherapy after MRM or mastectomy to the chest wall or axilla<br />

is restricted to patients with high risk of recurrence. These include<br />

tumors larger than 5 cm in maximum diameter and those with<br />

four or more involved axillary lymph nodes, those with positive<br />

surgical margins on resection, and those with involvement of the<br />

skin or underlying chest wall. 12 It can also be a very effective local<br />

modality in controlling or shrinking tumors that are not amenable<br />

to surgical therapy.<br />

Preoperative and locoregional treatment<br />

The initial management should be neoadjuvant chemotherapy<br />

with Doxorubicin- or Epirubicin-based or Paclitaxel- or Docetaxel<br />

based chemotherapy. Patients with HER2 positive tumors should<br />

be considered for preoperative chemotherapy incorporating<br />

Trastuzumab.<br />

The advantages of neoadjuvant therapy include down staging of<br />

the tumor, improving operability of tumors and increasing the<br />

chances of BCT.<br />

For patients that respond to neoadjuvant chemotherapy, the<br />

following options are recommended 71,104-108 modified radical<br />

mastectomy, radiotherapy to the chest wall and supraclavicular<br />

nodes (plus internal mammary nodes if involved) with or without<br />

delayed breast reconstruction. In those women with LABC who do<br />

not have access to neoadjuvant chemotherapy because of<br />

economic constraints or radiotherapy, mastectomy with node<br />

dissection, when feasible, may still be considered in an attempt to<br />

achieve local-regional control. 12 The second option is BCT with<br />

surgical axillary staging, radiotherapy to the breast, supraclavicular<br />

nodes (plus internal mammary nodes if involved).<br />

However, for patients who fail to respond to preoperative<br />

chemotherapy, recommended treatment is to consider additional<br />

systemic chemotherapy and/or preoperative radiation.<br />

Adjuvant treatment<br />

Chemotherapy should contain an anthracycline. Acceptable<br />

regimens are 6 cycles of 5 Fluorouracil, Doxorubicin,<br />

Cyclophosphamide (FAC) or Cyclophosphamide, Epirubicin,<br />

5Fluorouracil (CEF). Sequential addition of Taxanes has also<br />

proven very effective.<br />

Tamoxifen for 5 years should be recommended to pre- and<br />

postmenopausal women whose tumours are hormone responsive.<br />

Aromatase inhibitors like Letrozole, Anastozole and Examestane<br />

can be used in post menopausal patients.<br />

Surgical oophorectomy causing ovarian ablation is a very<br />

effective therapy in the treatment of locally advanced and<br />

metastatic ER positive breast cancer in premenopausal women.<br />

This therapy is one that would be very feasibly applied in Africa<br />

provided that it was acceptable to the woman.<br />

Metastastic and recurrent cancer<br />

The standard evaluation procedure for this group of patients<br />

includes history and clinical examination, full blood count, liver<br />

function test, platelet count , chest X-ray, limited skeletal survey<br />

especially of any long or weight bearing bones that are painful,<br />

biopsy of recurrence, evaluation of hormone receptor status,<br />

ultrasound of the abdomen or CT where available.<br />

Others include bone scans, MRI, PET, and determination of<br />

HER2 status of the tumor. These are however tall orders in<br />

countries with limited resources and where there are no medical<br />

insurances to cover the cost of these investigations. Pragmatism<br />

is required in this setting.<br />

Treatment of local recurrence<br />

Local recurrence can occur in two settings; post BCT or MRM.<br />

Post MRM local recurrence should undergo local resection of<br />

the recurrence where feasible without unnecessarily endangering<br />

the lives of the patients. In addition, radiotherapy of the involved<br />

area should be done if the chest wall was not previously irradiated<br />

or if it could be done safely.<br />

Post BCT patients should undergo a total mastectomy.<br />

Systemic therapy for local recurrence could be adjuvant<br />

chemotherapy or endocrine therapy as in LABC.<br />

Addition of Hyperthermia to radiotherapy has been shown in<br />

some trials to cause a statistically significant increase in local<br />

tumor response and greater duration of local control. This is<br />

however technically demanding and resource intensive.<br />

Systemic disease<br />

Systemic recurrence and metastatic cancers are incurable, so the<br />

goals of therapy are to prolong survival, improve quality of life with<br />

minimal morbidity or toxicity from the therapy.<br />

Minimally toxic endocrine therapy is therefore preferred to the<br />

use of cytotoxic therapy whenever indicated. Endocrine therapies<br />

are indicated in women with hormone receptor status, bone or<br />

soft tissue disease only and those with limited asymptomatic<br />

visceral disease. For post menopausal women, the choice is<br />

between Tamoxifen and aromatase inhibitors, with aromatase<br />

inhibitors having a slight edge especially in those who have taken<br />

anti-estrogen previously.<br />

For premenopausal women who are anti-estrogen naïve, antiestrogen<br />

with or without LHRH agonist is the preferred choice.<br />

Oophorectomy is an excellent cheap alternative where drugs are<br />

not available.<br />

Since the majority of African women with breast cancer are<br />

hormone receptor negative, few will benefit from endocrine<br />

therapy, chemotherapy will be the option in most cases.<br />

Premenopausal patients who have taken anti-estrogen<br />

Innovation and clinical specialities: oncology<br />

previously have a choice of either surgical or radiotherapeutic<br />

oophorectomy or luteinizing hormone-releasing hormone (LHRH)<br />

agonists with or without an antiestrogen.<br />

Endocrine therapies in postmenopausal women include<br />

selective, nonsteroidal aromatase inhibitors (anastrozole and<br />

letrozole); steroidal aromatase inhibitors (exemestane); pure<br />

antiestrogens (fulvestrant); progestin (megestrol acetate);<br />

androgens (fluoxymesterone); and high-dose estrogen (ethinyl<br />

estradiol). In premenopausal women, therapies include LHRH<br />

agonists (goserelin and luprolide); surgical or radiotherapeutic<br />

oophorectomy; progestin (megestrol acetate); androgens<br />

(fluoxymesterone); and high-dose estrogen (ethinyl estradiol).<br />

Chemotherapy is the best option in women with estrogen and<br />

progesterone receptor-negative tumors, symptomatic visceral<br />

metastasis, or endocrine therapy refractory disease.<br />

The higher rates of objective response and longer time to<br />

progression of combination chemotherapy are at the expense of<br />

increased toxicity with little survival benefit.<br />

Therefore, there is no significant advantage of combination<br />

chemotherapy over sequential single agents.<br />

Preferred first-line chemotherapies include sequential single<br />

agents or combination chemotherapy. Among preferred first-line<br />

single agents, are doxorubicin, epirubicin, pegylated liposomal<br />

doxorubicin, paclitaxel, docetaxel, capecitabine, vinorelbine (all<br />

category 2A), and gemcitabine (category 2B). Among preferred<br />

first-line combination regimens are cyclophosphamide,<br />

doxorubicin, and fluorouracil (FAC/CAF); fluorouracil, epirubicin,<br />

cyclophosphamide (FEC); doxorubicin, cyclophosphamide (AC);<br />

epirubicin, cyclophosphamide (EC); doxorubicin in combination<br />

with either docetaxel or paclitaxel (AT); cyclophosphamide,<br />

methotrexate, fluorouracil (CMF); docetaxel, capecitabine;<br />

gemcitabine, paclitaxel.<br />

Patients with tumors that are HER2-positive may derive benefit<br />

from treatment with trastuzumab as a single agent or in<br />

combination with selected chemotherapeutic agents. 27% of<br />

patients treated with a combination of Trastuzumab and<br />

doxorubicin/cyclophosphamide chemotherapy develop significant<br />

cardiac dysfunction making this regime unsafe and unpopular. 71<br />

Treatment of complications<br />

In Africa, a good number of women present with fungating/<br />

ulcerating masses and many of them are so ill that they can not<br />

undergo surgery or radiotherapy immediately. The following are<br />

some useful supportive measures:<br />

✚ Dressing of the wound with honey and metronidazole<br />

cleanses and remove the odor. This measure in addition to the<br />

use of neoadjuvant chemotherapy has largely reduced the<br />

need for toilet mastectomy.<br />

✚ Clean malignant ulcers are prone to secondary hemorrhage;<br />

topical formalin is effective in this setting.<br />

✚ Pain is another significant problem and this may be due to the<br />

disease, therapy or depression. Optimal pain management is<br />

very crucial to improving the quality of life. If pain occurs, there<br />

should be prompt oral administration of drugs in the following<br />

order: non-opioids (aspirin and paracetamol); then, as<br />

necessary, mild opioids (codeine); then strong opioids such as<br />

morphine, until the patient is free of pain. To calm fears and<br />

anxiety, additional drugs – “adjuvants” – should be used. To<br />

maintain freedom from pain, drugs should be given “by the<br />

clock”, that is every 3-6 hours, rather than “on demand” This<br />

three-step approach (see figure 2) of administering the right<br />

drug in the right dose at the right time is inexpensive and 80-<br />

90% effective. Surgical intervention on appropriate nerves may<br />

provide further pain relief if drugs are not wholly effective. 109<br />

✚ Anemia as a result of the disease or chemotherapy is often<br />

under treated and underestimated in patients. It has a negative<br />

impact on quality of life and survival. It will require blood<br />

transfusion in some women. The introduction of recombinant<br />

human erythropoietin (epoetin) has provided an effective and<br />

convenient treatment of anemia without the risks of blood<br />

transfusion. Epoetin is also effective for the prevention of<br />

anemia and reduction of transfusion requirements in patients<br />

with a high risk of developing anemia during chemotherapy. 110-112<br />

✚ Lymphedema of the arm is a very distressing complication<br />

which may occur as a result of the disease itself or as a result<br />

of surgery or radiotherapy in the treatment of breast cancer.<br />

Treatment options include compression treatments (using<br />

compression bandage or garments and pneumatic<br />

compression devices), therapeutic exercises and<br />

pharmacotherapy (antibiotics, flavonoids, hyaluronidase, and<br />

selenium). Diuretics have not been found useful. 113,114<br />

✚ Respiratory distress in advanced breast cancer may be as a<br />

result of pleural effusion or deposits in the lungs. Closed<br />

thoracostomy tube drainage with pleurodesis using<br />

Tetracycline or Bleomycin is an effective treatment. Lung<br />

metastasis can be treated with steroids inhalers, bronchodilators,<br />

diuretics, anxiolytics, chest physiotherapy and oxygen. 5<br />

✚ Neurological complications include cerebral metastases,<br />

spinal, leptomeningeal, cranial and peripheral nerve<br />

metastases. 115 Treatment includes steroids,<br />

radiotherapy and surgery for localized metastases.<br />

Younger women with breast cancer are more prone to physical<br />

and psychological distress which makes them have poorer quality<br />

of life outcomes. These arise as a result of the disease and the<br />

complications of treatment. Gonadal toxicity leading to irregular<br />

menses, amenorrhea and premature menopause is especially<br />

disturbing for African patients, the majority of whom are in their<br />

reproductive age group. Other problems like Alopecia, fertility<br />

problems and the cost of treatment may severely affect<br />

relationship especially among young couples. In this context, a<br />

multi disciplinary approach is important which will involve<br />

psychologists, social welfare/support groups and various<br />

advocacy groups where survivors of breast cancer can share their<br />

experiences and support one another. 116-120<br />

Prognosis<br />

Natural history<br />

The natural history of breast cancer in 250 untreated women<br />

revealed the following statistics; Median survival of untreated breast<br />

cancer was 2.7 years after initial diagnosis. The 5- and 10-year<br />

survival rates were 18.0 and 3.6%, respectively. Only 0.8% survived<br />

for 15 years or longer. Autopsy data confirmed that 95% of these<br />

women died of breast cancer, while the remaining 5% died of other<br />

causes. Almost 75% of the women developed ulceration of the<br />

breast during the course of the disease. The longest surviving<br />

patient died in the nineteenth year after diagnosis. 121<br />

With modern treatment, the 5-year survival rate for stage I<br />

is 52%; for stage IIIb patients, 48%; and for stage IV patients, 18%.<br />

Prognostic Iindicators:<br />

Tumor size<br />

Prognosis deteriorates with increasing tumor size, which is an<br />

independent predictor of survival in node-negative patients and<br />

correlates with the incidence of nodal metastases.<br />

Staging<br />

The status of the axillary lymph nodes is one of the most useful<br />

prognostic indicators for breast cancer, with average 10-year<br />

survival rates of 60-70% for node-negative patients, dropping to<br />

20-30% in node-positive patients.<br />

Histopathology<br />

✚ Histologic type<br />

• Carcinoma in situ, because it is a preinvasive condition, is<br />

curable if completely removed, although 16% of patients with<br />

carcinoma in situ develop invasive recurrence after local<br />

excision of ductal carcinoma in situ, usually high grade.<br />

Similarly, 18% of patients develop invasive recurrence after<br />

lobular carcinoma in situ excision.<br />

• Well-differentiated invasive cancers have a relatively good<br />

prognosis if they are tubular, mucinous, cribriform, or<br />

secretory.<br />

• Medullary carcinoma is probably of intermediate prognosis, but<br />

different studies have used different criteria for its definition.<br />

• Invasive ductal and invasive lobular carcinomas have a less<br />

favorable prognosis but are influenced heavily by other factors.<br />

✚ Cytologic grade<br />

• Cytologic grade is the best predictor of disease prognosis in<br />

carcinoma in situ but is dependent on the grading system<br />

used, such as the Van Nuys classification (high-grade, lowgrade<br />

comedo, low-grade noncomedo).<br />

• The grading of invasive carcinoma is also important as a<br />

prognostic indicator, with higher grades indicating a worse<br />

prognosis. Microscopic criteria for grading are shown in<br />

Table 5.<br />

✚ Lymphovascular: Lymphatic invasion, vascular invasion,<br />

microvessel quantification, and lymphoplasmacytic infiltration<br />

are associated with a worse prognosis.<br />

✚ Hormone receptor status: With the aid of gene expression<br />

studies using DNA microarrays and immunohistochemistry,<br />

several distinct biologic breast cancer subtypes have been<br />

identified. These subtypes differ markedly in prognosis and in<br />

the number of potential therapeutic targets they express.<br />

The intrinsic subtypes include 2 main subtypes of estrogen<br />

receptor (ER)–negative tumors (basal-likeand human epidermal<br />

growth factor receptor-2 positive/ER- [HER2_/ER-] subtype) and<br />

at least 2 types of ER+ tumors (luminal A and luminal B). The basal<br />

like subtype carries poor biologic (worse grade) and clinical<br />

prognostic indicators like positive axillary nodes.<br />

This subtype was found to be more prevalent in pre-menopausal<br />

African-American women compared to post menopausal African-<br />

American women and other races. 122 This finding may be one of the<br />

reasons why African-American women with breast cancer have<br />

high grade, late stage tumor and with poor prognosis and poor<br />

survival outcome.<br />

The similar clinical outcome of native African women with breast<br />

cancer may tempt one to extrapolate these findings seen in<br />

African-American women. To lend credence to this fact, the few<br />

studies on hormone receptor status of breast cancer in native<br />

African women show that the majority of them are Estrogen or<br />

Progesterone negative 123-125 .<br />

There are also several other provocative parallels between<br />

African-American and native African breast cancer patients which<br />

include a younger age distribution and a greater prevalence of high<br />

grade, estrogen-receptor-negative disease among breast cancer<br />

patients in the Ghanaian and Nigerian populations of western<br />

Africa similar to the patterns of breast cancer reported among<br />

African-American women. Western African populations served as<br />

the source for most of the slave trade to colonial North America,<br />

and therefore share a common ancestry with present-generation<br />

African Americans. These parallels suggest the possible<br />

contribution of founder effects. 16<br />

However, further research needs to be done in this area before<br />

reaching any conclusion is reached as the African-Americans are<br />

Hispanics, Caucasians and Africans. In addition other<br />

socioeconomic factors and environmental factors may contribute<br />

to the clinical outcome seen. 126,127<br />

✚ Immunohistochemistry<br />

• The most widely used tests are for the estrogen receptors (ER)<br />

and progesterone receptors (PR). Immunohistochemistry<br />

analysis of heat-treated paraffin sections has largely<br />

superseded the enzyme-linked immunosorbent assay (ELISA)<br />

ligand-binding assay. ER- and PR-positive status (ie, >10 fmol<br />

on ELISA; >15 H-score on immunohistochemistry) predict<br />

improved response to endocrine treatment, time to relapse,<br />

and overall survival.<br />

• Immunohistochemical positivity for c-erb-B2 and p53 is<br />

associated with a worse prognosis.<br />

• HER-2 status: The human epidermal growth factor receptor-2<br />

(HER-2/neu) is a well-characterized biomarker in the biology of<br />

breast carcinoma that has had immediate impact on clinical<br />

medicine. The positive status of HER-2/neu is associated with<br />

a younger age and several adverse prognostic factors, i.e.,<br />

advanced stage, absence of estrogen and progesterone<br />

receptors, metastasis to axillary lymph nodes, and high<br />

nuclear grade. In addition, women diagnosed with<br />

positiveHER-2/neu breast carcinoma generally have relative<br />

resistance to anthracycline-based chemotherapy, tamoxifen<br />

therapy, and have shorter disease-free and overall survival. 128<br />

Other prognostic indicators<br />

Advances, in the knowledge of the molecular mechanisms that<br />

influence normal and aberrant cell growth, have led to the<br />

identification of an increasing number of surrogate biomarkers,<br />

which have been correlated with prognosis or used as predictors<br />

of response to specific treatments. These novel prognostic<br />

markers can be classified as follows:<br />

✚ Oncogene products<br />

• Bcl-2<br />

• p53<br />

• HER-2/neu<br />

• Cyclin D1<br />

• Nm23<br />

✚ Proteases<br />

• uPA<br />

• Cathepsin D<br />

• Tenascin C<br />

✚ Markers of proliferation - Ki-67<br />

HER-2/neu identifies patients with a poor prognosis. These<br />

patients are likely to respond to treatment with trastuzumab<br />

(Herceptin).<br />

Tumors positive for Ki-67 have a high metastatic potential and<br />

warrant the possible use of early aggressive therapy.<br />

uPA and cathepsin D identify poor prognosis node-negative<br />

tumors. In these cases, chemotherapy can be offered.<br />

The use of gene expression profiling to detect breast carcinoma<br />

has already shown that the differential expression of specific genes<br />

is a more powerful prognostic indicator than traditional<br />

determinants such as tumor size and lymph node status. These<br />

molecular assays are awaiting clinical validation.<br />

Prevention<br />

Screening as currently practiced can reduce mortality but not<br />

incidence, and then only in a particular age group. Advances in<br />

treatment have produced significant but modest survival benefits.<br />

A better appreciation of factors important in the etiology of breast<br />

cancer would raise the possibility of disease prevention. Currently,<br />

prevention strategies fall into two groups: chemoprevention and<br />

surgical prophylaxis.<br />

Chemoprevention is defined as the systemic use of natural or<br />

synthetic chemical agents to reverse or suppress the progression<br />

of a premalignant lesion to an invasive carcinoma 129 . Tamoxifen is<br />

currently the only agent that has been approved clinically for use<br />

in women with high risk of developing cancer. Raloxifene,<br />

selenium, retinoids, aromatase inhibitors and cyclo-oxygenase 2<br />

inhibitors require further clinical investigation before adoption in<br />

this context.<br />

Surgical prophylaxis: by either a bilateral mastectomy or<br />

oophorectomy, is another avenue of prevention. Some studies<br />

profile after such operation. 130<br />

Dietary intervention If specific dietary factors are found to be<br />

associated with an increased risk of breast cancer dietary<br />

intervention will be possible. However, reduction of dietary intake<br />

of such a factor in whole communities may well be difficult to<br />

achieve without major social and cultural changes. Dietary fat<br />

reduction and exercise decrease the circulating serum oestradiol<br />

level, but whether this in turn leads to a reduction in the incidence<br />

of breast carcinoma has not been determined conclusively. 131<br />

Breast cancer and pregnancy<br />

Pregnancy associated breast cancer is defined as breast cancer<br />

diagnosed during pregnancy or lactation or one year post partum.<br />

Breast cancer and pregnancy can be classified into three main<br />

situations; these are (a) breast cancer that is detected during the<br />

evolution of pregnancy, (b) breast cancer that is detected during<br />

lactation or postpartum, and (c) pregnancy in patients who have<br />

had a previous breast cancer. Cancer complicates approximately<br />

1 per 1000 pregnancies and accounts for one-third of maternal<br />

deaths during gestation. The prevalence of breast cancer during<br />

pregnancy is increasing due to delayed onset of childbearing.<br />

Breast cancer is diagnosed in approximately 1 in 3000<br />

pregnancies. The incidence ranges from 0.76% to 3.8% of breast<br />

cancer cases. The median age of pregnant women affected with<br />

breast cancer is 33 years. In a recent review in Nigeria, 12% of the<br />

patients with Breast Cancer were pregnant or lactating and 74%<br />

were premenopausal , making it the most frequently occurring<br />

malignancy during pregnancy, along with cancer of the uterine<br />

cervix.(5) Treatment decisions for breast cancer patients during<br />

pregnancy become most difficult because not only the mother but<br />

also the fetus is involved. The final advice should be based upon<br />

the following considerations:<br />

✚ the parents’ decision whether or not to continue with the<br />

pregnancy,<br />

✚ the period of pregnancy when the breast cancer is<br />

diagnosed, and<br />

✚ the stage of the breast cancer.<br />

A detailed guideline on the management of breast cancer in<br />

pregnancy can be found in the NCCN Clinical Practice Guidelines<br />

in Oncology Breast cancer V.1.2007 at www.nccn.org.<br />

Early studies have indicated that the prognosis of breast cancer<br />

in pregnancy is very poor; however, more recent studies with more<br />

careful consideration of age and the stage of the disease show no<br />

significant differences. Evidence is lacking that termination of<br />

pregnancy changes the outcome of breast cancer. Pregnancy<br />

after breast cancer does not alter the outcome of treatment. The<br />

ideal interval between treatment for breast cancer and subsequent<br />

pregnancy is unknown. 132<br />

Breast cancer in males<br />

Male breast cancer is an uncommon disease although the<br />

incidence has increased over the past 25 years. Less than 1% of<br />

all breast cancer patients are male. Rates of male breast cancer<br />

vary widely between countries: in Uganda and Zambia the annual<br />

incidence rates are 5% and 15%, respectively of all breast cancer<br />

cases. These relatively high rates have been attributed to endemic<br />

infectious diseases causing liver damage, leading to<br />

hyperestrogenism. By contrast, the annual incidence of male<br />

breast cancer in Japan is less than five per million, in parallel with<br />

the lower than average incidence of female breast cancer in that<br />

country. Jewish men are the only racial group with a higher than<br />

average incidence (2•3/100 000 per year), irrespective of living in<br />

Israel or the USA. 133 Risk factors for Breast Cancer include Genetic<br />

(BRCA2, Klinefelter’s syndrome), Lifestyle (Obesity, Alcohol,<br />

Estrogen intake), Work (High ambient temperature, Exhaust<br />

emissions), and Disease (Testicular damage, Liver damage,<br />

Radiotherapy to chest) The predominant histological type of<br />

disease is invasive ductal, which forms more than 90% of all male<br />

breast tumors.<br />

Much rarer tumour types include invasive papillomas and<br />

medullary lesions. Lobular carcinoma of the male breast has been<br />

reported not only in men with Klinefelter’s syndrome, but also in<br />

genotypically normal men with no previous history of oestrogen<br />

exposure or gynaecomastia. In large studies of male breast cancer,<br />

104 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: oncology<br />

oestrogen receptor positivity has been reported in more than 90%<br />

of tumours, with 92–96% being progesterone-receptor positive.<br />

Some studies suggested that breast cancer has a worse<br />

prognosis in men than in women, but if age- matched and stagematched<br />

breast cancer is compared, there is no difference<br />

between the sexes 18;134;135<br />

Future trends and controversies<br />

✚ Diagnosis and early detection Several new technologies,<br />

apart from mammography are being evaluated to improve the<br />

early detection of breast cancer. These include non ionizing<br />

imaging techniques like Ultrasonography and MRI. Other<br />

imaging tools being evaluated include scintimammography,<br />

positron emission tomography, magnetic resonance<br />

spectroscopy, optical imaging, thermo-acoustic computed<br />

tomography, microwave imaging, Hall effect imaging etc.<br />

✚ Molecular targets and new drugs HER-2 Pertuzumab<br />

(also known as 2C4, Omnitarg) is a new recombinant<br />

humanised monoclonal antibody that also binds the<br />

extracellular portion of HER2, which causes steric hindrance<br />

and impairs receptor dimerisation. Ongoing phase-I testing<br />

has shown activity in patients with breast cancer that is either<br />

HER2-negative and trastuzumab-refractory HER2-positive.<br />

✚ Tyrosine kinase, cyclines, and proteosoma Most tyrosinekinase<br />

inhibitors are in preclinical investigations and only a few<br />

have been tested in patients with advanced breast cancer.<br />

Gefitinib is an inhibitor of the tyrosine kinase of human<br />

epidermalgrowth-factor receptor (HER1) and has shown some<br />

antitumour activity in preclinical studies and a phase II trial of<br />

patients heavily pretreated for metastatic breast cancer.<br />

✚ Insulin-like growth factor (IGF) IGF is an interesting<br />

therapeutic target in breast cancer because its ligands and<br />

receptors are often overexpressed and are implicated in<br />

proliferation, transformation, and metastasis. The IGF system<br />

includes ligands IGF-I and IGF-II, receptors IGF-IR and IGF-IIR,<br />

and six known IGF-binding proteins. These binding proteins<br />

are promising targets for the manipulation of endocrine<br />

responsiveness and resistance to Trastuzumab.<br />

✚ Angiogenesis Bevacizumab is a recombinant, humanised<br />

monoclonal antibody to vascular endothelial growth factor that<br />

has shown some efficacy when used alone in phase II clinical<br />

trials. Several anti-angiogenic drugs have been tested for<br />

efficacy, including thalidomide, endostatin, angiostatin,<br />

SU6668, SU11248, and cyclo-oxygenase 2 (COX-2) inhibitors.<br />

COX-2 also improves the efficacy of<br />

✚ Receptors as targets for radionuclides Efficacy of targeted<br />

therapy depends on the biologically relevant quality and<br />

quantity of the specific compound. This treatment needs to<br />

reach the target efficiently and accurately and exert a selective<br />

therapeutic effect. The development of biomarkers to assess<br />

in-vivo responses and the ability to use such biomarkers as<br />

targets for specific radionuclide treatment represent great<br />

challenges in cancer medicine.<br />

In situ ablation<br />

In situ ablation of the primary tumour has been suggested as an<br />

alternative to surgery. There are preliminary reports on methods<br />

using cryosurgery, or coagulating with heat, delivered by a laser<br />

fiberoptic technique .<br />

Who will perform breast surgery?<br />

Within the next decade the number of patients undergoing axillary<br />

surgery will diminish as a result of improved staging by sentinel<br />

node biopsy. A greater part of the patients will have only breast<br />

resection, and these operations can be performed as day-case<br />

surgery, even under local anaesthesia. The surgical challenges<br />

during the next decade will be immediate breast reconstruction<br />

and various oncoplastic procedures. Therefore breast surgery will<br />

increasingly be performed by plastic surgeons. General surgeons<br />

will not be so interested in carrying out all the other rather<br />

undemanding breast procedures. 136<br />

Controversies<br />

✚ Relevance.<br />

✚ The place of post mastectomy radiotherapy in early breast<br />

cancer especially in women with T1 ,T2 and one to three<br />

positive lymph nodes.<br />

✚ Sequencing of post mastectomy radiotherapy and breast<br />

reconstruction. 137<br />

✚ The impact of mammographic screening in reduction of<br />

mortality in breast cancer.<br />

Conclusion<br />

Management of breast cancer is a major challenge in resource<br />

limited countries.<br />

Efforts should be geared towards early diagnosis, prompt and<br />

standardized treatment to reduce the burden of advanced disease<br />

in African women, majority of who are worse hit in the most<br />

productive part of their life time.<br />

Our knowledge about breast cancer is evolving, but is still<br />

limited with respect to its etiology and biology, and with respect to<br />

its features in individual countries and cultures.<br />

Further research is needed to understand the role of genetics<br />

and environment in the etiology of breast cancer in Africa.<br />

Recommnedations<br />

In high-resource countries, evidence-based guidelines outlining<br />

optimal approaches to early detection, diagnosis, and treatment of<br />

breast cancer have been defined and disseminated. These<br />

guidelines unfortunately are not applicable in countries with<br />

resource constraints as they are not economically feasible or<br />

culturally appropriate.<br />

The following recommendations might be considered appropriate<br />

in the resource-poor countries of Africa. Following the Breast Health<br />

Global Initiative we have stratified the recommendations into Basic,<br />

Limited, Enhanced and Maximal. 10-12,138<br />

Definition of stratification terms<br />

✚ Basic level – Core resources or fundamental services<br />

absolutely necessary for any breast healthcare system to<br />

function. By definition, a healthcare system lacking any basiclevel<br />

resource would be unable to provide breast cancer care<br />

to its patient population. Basic-level services are typically<br />

applied in a single clinical interaction.<br />

✚ Limited level – Second-tier resources or services that<br />

produce major improvements in outcome, such as increased<br />

survival, but which are attainable with limited financial means<br />

and modest infrastructure. Limited-level services may involve<br />

single or multiple clinical interactions.<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 105


Innovation and clinical specialities: oncology<br />

✚ Enhanced level – Third-tier resources or services that are<br />

optional but important. Enhanced-level resources may produce<br />

minor improvements in outcome but increase the number and<br />

quality of therapeutic options and patient choice.<br />

✚ Maximal level – High-level resources or services that may be<br />

used in some high-resource countries, but nonetheless should<br />

be considered lower priority than those in the basic, limited, or<br />

enhanced categories on the basis of cost or impracticality for<br />

limited-resource environments. In order to be useful, maximallevel<br />

resources typically depend on the existence and<br />

functionality of all lower-level resources.<br />

Our own recommendations include:<br />

✚ Early Detection and Diagnosis: Possible less resourceintensive<br />

methods for earlier diagnosis of breast cancer like<br />

education in breast awareness, training in breast selfexamination<br />

(BSE), regular clinical breast examination (CBE) by<br />

experienced personnel and diagnostic ultrasound may be the<br />

option in resource limited countries as mammography<br />

screening may be resource intensive. 69<br />

✚ To improve breast pathological capacity and services in Africa,<br />

the following approaches may be explored; including training<br />

pathologists, establishing pathology services in centralized<br />

facilities, and organizing international pathology services. In<br />

particular it is important that estrogen and progesterone<br />

receptor status of tumors be identified.<br />

✚ As staging is crucial to treatment decisions and prognosis, a<br />

thorough clinical evaluation after the diagnosis of breast cancer<br />

to check for clinically obvious indications of metastases to the<br />

lymph nodes and other areas is crucial. In addition, tests to<br />

assess the presence of metastases to the lungs, liver, and<br />

bone provide valuable information, if available. Hormone<br />

receptor testing of pathology specimens should be part of the<br />

pathology services<br />

✚ More training for surgeons in BCT and Sentinel node biopsy. ❏<br />

Responding to challenges<br />

in physical therapy<br />

This paper describes a range of contemporary challenges affecting the physical therapy profession and its<br />

practice around the world, and the way the profession is responding to them.<br />

Physical therapists (called physiotherapists in some<br />

countries) provide services to individuals and populations to<br />

develop, maintain and restore maximum movement,<br />

functional ability and quality of life throughout the lifespan. Their<br />

practice encompasses the spheres of promotion, prevention,<br />

treatment/intervention, habilitation and rehabilitation. Their work<br />

includes incorporating the aspects of physical, psychological,<br />

emotional, and social wellbeing into their practice. The practice of<br />

physical therapy includes treatments/interventions for<br />

patients/clients with a multiplicity of diseases, disorders and<br />

conditions of the musculoskeletal, neuromuscular, cardiovascular/<br />

pulmonary, integumentary, genito-urinary, endocrine, and<br />

immunological systems. Working with patients/clients, other<br />

health professionals, families, caregivers, and communities,<br />

physical therapists examine movement potential and establish<br />

mutually agreed upon goals, using knowledge and skills unique to<br />

them.<br />

Physical therapists practise in a wide variety of settings: not only<br />

in hospitals and other acute care settings but also in the<br />

community, out-patient clinics, private practices, rehabilitation<br />

centres, schools, work places, recreational facilities and public<br />

places. As governments seek to reduce healthcare budgets,<br />

services are moved from the expensive hospital environment to<br />

more community-based service delivery settings. Physical<br />

therapists have responded to the increasingly diverse service<br />

delivery system in flexible, responsive and unique ways that are<br />

reflective of local needs and resources.<br />

As the international voice of the profession, the World<br />

Confederation for Physical Therapy (WCPT) is instrumental in<br />

leading the profession, providing strong communication on behalf<br />

of its member organisations. WCPT is the international body<br />

founded in 1951 to represent the global interests of physical<br />

therapists and their patients/clients. It represents 101 member<br />

organisations and more than 300 000 physical therapists<br />

worldwide, providing the sole international voice for the profession.<br />

Evolution of the profession of physical therapy<br />

Physical therapy firmly established itself in the 20th century. Its<br />

growth was triggered by the large numbers of people injured<br />

particularly in World War I and and by the raging polio epidemics<br />

leaving untold numbers of children and adults with paralysis.<br />

Educated at the highest levels, physical therapists now deliver<br />

services as autonomous practitioners.<br />

Professional challenges<br />

Physical therapy now faces a number of new challenges around<br />

the world, which are being addressed by the World Confederation<br />

for Physical Therapy (WCPT).<br />

These include the growth of lifestyle-related diseases, such as<br />

arthritis, cardiovascular disease, diabetes and asthma; new<br />

technologies such as robotics; increasingly complex service<br />

delivery systems; the supply of physical therapists to meet service<br />

Innovation and clinical specialities: physical therapy<br />

delivery requirements; and public access to physical therapy<br />

services.<br />

The World Confederation for Physical Therapy is addressing this<br />

range of challenges through its policies, programmes and<br />

advocacy.<br />

Lifestyle related diseases<br />

Chronic and lifestyle related diseases are the primary causes of<br />

death and disability in many countries, including those with low<br />

and middle incomes. Physical therapists are increasingly<br />

undertaking a primary care role, specifically in relation to the<br />

prevention and management of those lifestyle diseases that are<br />

associated with low levels of physical activity. As experts in<br />

movement and exercise and with a thorough knowledge of<br />

anatomy, physiology and the effects of pathology on all systems,<br />

physical therapists are the ideal professionals to promote, guide,<br />

prescribe and manage exercise activities. Exercise promotes wellbeing<br />

and fitness. It is a powerful intervention for strength, power,<br />

endurance, flexibility, balance, relaxation, recreation and the<br />

remediation of functional limitations. There is evidence of the cost<br />

benefits that this intervention can bring:<br />

✚ One study showed statistically significant decreases in body<br />

mass index (BMI) over time in an intervention group of people<br />

with intellectual disabilities compared with a non-intervention<br />

group (Chapman et al 2009).<br />

✚ A home-based programme of strength and balance retraining<br />

exercises, individually prescribed by a physical therapist, was<br />

effective in reducing falls and injuries in women aged 80 years<br />

and older. The benefit, for those who keep exercising,<br />

continued over a 2-year period (Campbell et al 1999). The<br />

reduction in healthcare costs per individual for treating fallrelated<br />

injuries was 1.85 times higher than the cost of<br />

implementing a fall prevention programme (Hektoen et al<br />

2009).<br />

A range of policies and resources has been developed by WCPT<br />

for use by member organisations to support of the role of physical<br />

therapists in this area.<br />

New technologies<br />

Technology has been developing apace in recent years and,<br />

physical therapists with their educational background in the<br />

physical, biological, biomechanical, and kinesiological sciences<br />

can engage readily with these new technologies.<br />

Technology for delivering services<br />

Physical therapists have been using electronic channels, such as<br />

the telephone and the internet, to augment their service provision<br />

to patients and clients and to help to reduce the costs of service<br />

delivery. For example, a 12-week home-based tele-rehabilitation<br />

programme delivered to people with multiple sclerosis resulted in<br />

improved functional outcomes. The individualised exercise<br />

programmes devised during a face-to-face consultation with a<br />

physical therapist were monitored by online video conferencing.<br />

Advantages of this form of delivery included the ability to monitor<br />

performance, make progressions and address questions and<br />

complications promptly. Tele-rehabilitation was well accepted by<br />

the programme recipients and cost effective for providers<br />

(Finkelstein et al 2008).<br />

Web-based physical therapy advice is another means of<br />

providing prompt, cost-efficient access to physical therapy<br />

services, especially for those in remote areas. Simultaneous<br />

management of many people and access 24 hours a day are<br />

advantages of this form of self-management. The majority of users<br />

of this sort of low cost service were satisfied with the advice they<br />

received, did not require further health services and completely<br />

self-managed their condition (see: www.physioadvice.scot.nhs.uk).<br />

Technology as treatments/interventions<br />

As well as affecting how physical therapy is delivered, many new<br />

technologies have influenced treatments and interventions.<br />

Physical therapists are involved in the rapidly expanding field of<br />

exoskeletons and their varied uses, including gait training during<br />

post-stroke recovery and helping patients with neurological<br />

disorders. Robotic systems that augment physical therapy have<br />

shown improvements in the level and speed of recovery of<br />

functional performance of individuals with hemiplegic upperextremity<br />

impairments. New biofeedback mechanisms such as<br />

myoelectric signals enable the user to control prosthetic limbs<br />

(Moffat 2004).<br />

The Guidelines for Physical Therapist Professional Entry Level<br />

Education (WCPT 2007) ensure that physical therapists education<br />

constantly evolves to keep pace with new developments.<br />

Technology for evidence and communication<br />

Electronic health records (EHR) are the future for recording and<br />

monitoring health care provision, not only at the individual level,<br />

but also by aggregation of anonymised data for administrative<br />

reporting and statistics. The challenge is to ensure that functional<br />

status information is included in EHR in a way that is consistent<br />

and reliable across service settings such that the value of physical<br />

therapy can be demonstrated and communicated. For example,<br />

current administrative records use the <strong>International</strong> Classification<br />

of Diseases to describe the health condition (e.g. M06.0<br />

Seronegative rheumatoid arthritis); however this does not describe<br />

whether the upper limbs or lower limbs are affected, whether the<br />

person can care for herself/himself and get around, or the sorts of<br />

equipment that they need to remain independent. Functional<br />

status information complements information about the disease<br />

and can be used to describe how the person lives with rheumatoid<br />

arthritis. To this end the WCPT has endorsed the <strong>International</strong><br />

Classification of Functioning, Disability and Health (WHO 2001)<br />

with the aim that it be used as the framework for describing the<br />

functional status of individuals as part of physical therapy practice.<br />

WCPT also promotes the use of the classification for evidencing<br />

the efficacy of physical therapy practice. High quality, reliable data<br />

collected in daily practice can be used to make comparisons<br />

between services, identify service training needs, highlight where<br />

research is needed, support evidence-based policies, and help<br />

identify the best balance of human resources for the health<br />

system.<br />

Many of these new developments are showcased at the WCPT<br />

Congress; an event conducted every four years, which brings<br />

together more than 3000 physical therapists from across the<br />

world.<br />

Education<br />

WCPT recognises that there is diversity in the social, economic,<br />

110 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: physical therapy<br />

cultural, and political environments in which physical therapist<br />

education is conducted. Professional education equips physical<br />

therapists with the appropriate knowledge and skills to practise in<br />

a variety of settings, as well as promoting the value of practising in<br />

these settings. <strong>International</strong>ly, the qualification to enter the physical<br />

therapy profession ranges from diploma to professional doctoral<br />

degree.<br />

With today’s level of physical therapist education, the research<br />

base for physical therapy has been expanded, supporting<br />

evidence-based practice. WCPT supports its member<br />

organisations as they develop new education programmes and<br />

revise existing programmes. It has done this by developing<br />

<strong>document</strong>s outlining the curriculum for entry level physical therapy<br />

education (WCPT 2007a), standards for physical therapy practice<br />

(WCPT 2007b) and guidelines for accreditation of physical therapy<br />

programmes (WCPT in preparation).<br />

Sufficient education programmes with qualified faculty<br />

particularly in low resource countries, is an impediment to ensuring<br />

adequate supply of physical therapists in these countries. WCPT<br />

uses its network to raise awareness of the need to recruit faculty<br />

members to work with local faculty in underserved areas on the<br />

development and sustainability of programmes.<br />

Resources for continuing education and development are a<br />

challenge for the profession. One key way to foster retention is to<br />

offer opportunities for physical therapists to continue postprofessional<br />

education studies even as they continue working in<br />

rural areas. WCPT’s focus on this issue through online courses,<br />

courses on DVDs and other initiatives will help to meet these<br />

education needs particularly where populations are least well<br />

served.<br />

Physical therapy service delivery<br />

Underserved areas<br />

In addressing the challenges of attracting physical therapists to<br />

underserved areas, WCPT has supported its member<br />

organisations by working alongside other health professional<br />

organisations and the Global Health Workforce Alliance (see:<br />

http://www.who.int/workforcealliance/en/) to produce the first<br />

guidelines on incentives for health professionals as part of the<br />

Positive Practice Environments campaign.<br />

The community based rehabilitation (CBR) movement and other<br />

grass roots level health services have been well supported by<br />

physical therapists. In many instances physical therapists have<br />

taken the lead in developing and running such services.<br />

Collaborative practice<br />

Physical therapists are active members of multi-professional<br />

teams, working in partnership with other health professionals to<br />

deliver services as equal partners. WCPT believes it is fundamental<br />

to professional autonomy that individual physical therapists should<br />

exercise their professional judgement as long as it is within the<br />

physical therapist's knowledge and competence. So it follows that<br />

their professional decisions cannot be controlled or compromised<br />

by persons from other professions (WCPT 2007c).<br />

In a growing number of countries, physical therapy has first<br />

contact/direct access status: in other words, a referral from<br />

another practitioner is not required, legally or ethically, before<br />

physical therapy services are provided. When physical therapists<br />

see patients without a referral, they can relieve the pressure on<br />

other health care providers (general practitioners and secondary<br />

referrals to hospitals). More people can be treated successfully at<br />

a lower cost to the health system and to the greater satisfaction of<br />

all involved (Holdsworth et al 2007).<br />

WCPT supports professions mutually recognising each others’<br />

skills and collaborative working methods which optimise the<br />

outcomes for their clients/patients.<br />

Regulatory environments that permit direct access and<br />

appropriate scope of practice enable physical therapists to offer a<br />

greater range of skills, thus increasing their ability to practice<br />

independently. In doing so they can relieve pressure on other<br />

professionals, such as physicians, enhance services to areas<br />

poorly served by other health care providers and improve the<br />

patient/client experience and outcomes.<br />

Regulation of the profession<br />

Regulation provides the right to practise physical therapy by the<br />

appropriately qualified individuals under the appropriate legislative<br />

framework. The purpose of regulation is to protect the public from<br />

incompetent, unqualified or unethical practitioners. The form of<br />

regulation varies across jurisdictions, but generally involves<br />

registration of those appropriately qualified to practise, protection<br />

of professional title, a system of accreditation and standards of<br />

practice and a process whereby those failing to meet ethical or<br />

practice standards can be removed from the register.<br />

WCPT encourages open and fair regulatory systems and works<br />

to reduce restrictive practices. In assisting member organisations<br />

and potential new members, WCPT has developed a range of<br />

position papers and policies on various aspects of the profession<br />

to provide information to governments, international nongovernmental<br />

organisations, the media and the public.<br />

Conclusion<br />

Many of the contemporary issues for physical therapy are<br />

interdependent. Where there is high quality professional education<br />

in accredited education programmes and a regulatory<br />

environment that supports autonomous practice, direct access to<br />

physical therapy services and respectful and collaborative<br />

relationships amongst health care providers, there are excellent<br />

opportunities for enhancing the delivery of physical therapy<br />

services to all that need them. ❏<br />

Population based surgery in low<br />

and middle income countries<br />

ARTICLE BY DAVID A SPIEGEL MD, AND RICHARD GOSSELIN MD, MPH<br />

Division of Orthopaedic Surgery, Childrens <strong>Hospital</strong> of Philadelphia, University of Pennsylvania School of Medicine,<br />

& University of California at Berkeley School of Public Health<br />

The burden of surgical diseases is large and is increasing, and there are enormous gaps in access to surgery<br />

between high and low income countries. Surgical services may be cost effective at the district level in LMICs,<br />

and providing access to essential surgery should be viewed as “primary prevention” of death and disability.<br />

The integration of essential surgical services into health systems, within the context of primary healthcare<br />

reforms, will surely improve population health.<br />

The world’s burden of surgical diseases is increasing, and<br />

considerable morbidity and mortality may be averted by<br />

providing access to safe and timely surgical care for injuries,<br />

acute abdominal conditions, complications of pregnancy, and<br />

many other diagnoses. 1-12 Injuries, especially due to road traffic<br />

crashes, have been recognized as emerging global public health<br />

concern. 1,2,7-9,11-17 For each death, many more individuals are left<br />

with a permanent disability. Although more than 230 million<br />

surgical procedures are estimated to be performed in the world<br />

each year, there are enormous gaps in access to surgical services<br />

both between and within countries 18 . Only 3.5% of major surgical<br />

procedures are performed in countries ranked in the lowest third<br />

in per capita health expenditure 18 . Surgery has been neglected as<br />

a population-based health strategy in low and middle income<br />

countries (LMICs), despite evidence to suggest that surgical<br />

conditions account for approximately 11% of the world’s disease<br />

burden 1 and basic surgical services may be cost effective even at<br />

the district level in LMICs 19-22 .<br />

The question is not whether universal access to “essential”<br />

surgical (including orthopaedics and anaesthesia) services would<br />

improve population-based health care in LMIC’s, but rather how<br />

this may be achieved. There has been a resurgence of interest in<br />

primary health care 23 as a means to strengthen health systems,<br />

and integration of essential surgery and anaesthesia within the<br />

context of primary healthcare reforms will undoubtedly improve<br />

population health. While recognizing that modern surgical services<br />

are usually available at a limited number of tertiary facilities in<br />

LMICs, there is a great need to provide access for the majority of<br />

the population, who reside in rural communities and are serviced<br />

by a district hospital or equivalent. This process will require a<br />

multidisciplinary, multisectoral effort, under the leadership of<br />

governments and their ministries of health.<br />

Barriers to the delivery of surgical and anaesthetic services<br />

Barriers to the delivery of safe and timely surgery and anaesthesia<br />

include deficiencies in capacity (infrastructure, physical resources,<br />

human resources) and quality (training and experience of<br />

caregivers). While recognizing the positive contributions from nongovernmental<br />

organizations and others in delivering surgical<br />

services, these vertical initiatives have often contributed to<br />

fragmentation within the health system, and may also foster<br />

complacency among health planners leading to inadequate<br />

resource allocation. In addition, the misperception that surgery is<br />

a high cost treatment benefitting only a limited segment of the<br />

population must be reversed if adequate resources are to be made<br />

available to support a functional district level surgical service.<br />

While considerable attention has been directed to addressing<br />

the global human resource crisis, there has been little mention of<br />

deficiencies in capacity of the health system to deliver surgical<br />

services, especially at the district level in LMICs 24,25 . Providing the<br />

capacity for facilities based services, including anaesthesia and<br />

surgery, is obviously more complex than many other health<br />

services such as immunizations, family planning, etc. Using the<br />

WHO’s surgical situational analysis questionnaire, significant<br />

deficiencies in capacity in Sierra Leone were identified, including<br />

shortages of water, electricity, supplies, and trained health<br />

workers 24 . Patients often had to purchase medical supplies prior to<br />

receiving treatment 24 . Kushner et al studied 132 district health<br />

facilities in 8 LMICs, and also identified significant shortfalls in<br />

infrastructure, physical resources, and in the procedures<br />

performed 25 . While incision and drainage of abscesses was<br />

performed at 73%, only 44% could perform a caeserian section.<br />

Only 33% of facilities treated open fractures, and 43% managed<br />

cases of osteomyelitis. Only 13% would treat a clubfoot.<br />

The capacity to deliver orthopaedic surgery is even more<br />

challenging, given the plethora of technological advancements<br />

from high income countries, which are resource intensive and<br />

costly. While attempting to transfer these technologies is<br />

unrealistic at the population level, we suggest that the majority of<br />

essential orthopaedic surgical procedures may be carried out at<br />

the district hospital, relying upon time honored methods of<br />

treatment and only the most basic equipment/implants, for<br />

112 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovation and clinical specialities: surgery<br />

example the closed management of fractures and dislocations,<br />

skeletal traction for fractures, irrigation and debridement for open<br />

fractures and infections (osteomyelitis, septic arthritis),<br />

amputations, and manipulation and casting for clubfoot. The<br />

challenge lies in teaching safe and reliable methods that have often<br />

been displaced by higher cost technologies, while maintaining<br />

similar outcomes. Another consideration is whether some of these<br />

technological advances may be adapted through low cost<br />

production and dissemination in LMICs 26-40 . The “SIGN”<br />

intramedullary nailing system for femur and tibia fractures is one<br />

example, although the implants are currently exported free of<br />

charge to low income countries, rather than being produced<br />

locally 41 . However, surgical complications from nailing fractures<br />

that were before successfully treated conservatively by traction or<br />

other means will need to be monitored. Another example of a low<br />

cost, transferable technology is the Ponseti method for clubfoot<br />

care, which relies upon serial casting followed by a minor surgical<br />

procedure (heelcord release) and then a long-term splinting 42-45 .<br />

While the method was developed in a high-income country (USA),<br />

excellent results have been achieved in several LMICs, even in<br />

patients up to 6 years of age 42 . The treatment may be delivered by<br />

nonmedical personnel, for example by orthopaedic clinical officers<br />

in Malawi or physiotherapists in Nepal 42-44 .<br />

Establishing and maintaining adequate capacity at the facilities<br />

level must begin with a situational analysis of all district level health<br />

facilities, to obtain a baseline and inform health planners as to<br />

which improvements are required. Furthermore, a mechanism for<br />

monitoring of capacity would be invaluable to ministries of health,<br />

and would contribute to strengthening each health information<br />

system. An example is the Service Availability Mapping (SAM)<br />

technology developed by the World Health Organization<br />

(WHO) 46,48 . Both district level and facilities based questionnaires are<br />

utilized, and health workers enter information into personal digital<br />

assistants (PDAs), and also record the location with a global<br />

positioning system device (GPS). The data is then processed<br />

(digital maps, graphs, etc.) and can be disseminated to help<br />

inform decision making and the development of health care<br />

policies. Mapping has been carried out in Tanzania 48 , Uganda,<br />

Albania, Rwanda, Kenya, and Zambia. Recently, a surgical<br />

questionnaire has been incorporated into this methodology, and a<br />

pilot project has been initiated in Mongolia in collaboration with the<br />

WHO and the ministry of health. Monitoring the capacity to deliver<br />

facilities based health services such as surgery will enhance the<br />

delivery of services. There is also the need to define the unmet<br />

need for surgical services at the population level, which will require<br />

community based surveys. This additional information will help<br />

prioritize services, and guide local allocation of resources.<br />

Once the capacity to provide basic orthopaedic and surgical<br />

services is available, trained health workers must be available to<br />

deliver the services. While only 10% of the world’s burden of<br />

disease is found in the Americas, this region has 37% of the global<br />

health work force and accounts for 50% of the world’s health<br />

spending 49 . In stark contrast, Sub Saharan Africa must utilize 3%<br />

of the world’s health work force to tackle 24% of the global<br />

disease burden, and accounts for less than 1% of the world’s<br />

health spending 49 . Brain drain has been an enormous problem,<br />

with workers migrating both between and within (rural to urban)<br />

countries 49-57 . There is a critical shortage of health workers in 57<br />

countries worldwide (36 in Africa) 49 . Common problems impacting<br />

health worker satisfaction include a lack of materials, inadequate<br />

salary, inadequate training or lack of supportive supervision, poor<br />

working conditions, inadequate living conditions, and inadequate<br />

professional recognition 50 . Other factors may include better<br />

opportunities in the private sector, with non-governmental<br />

organizations, and in other countries. A nationwide survey in<br />

Uganda demonstrated that less than 50% of health workers were<br />

satisfied, and more than 50% of physicians would prefer to<br />

emmigrate 51 . A mixture of both financial and non-financial<br />

incentives must be provided in order to retain health workers.<br />

There will never be enough surgeons to staff even the tertiary<br />

facilities in LMICs, let alone primary health care facilities, for<br />

decades to come. A recent report from Sierra Leone <strong>document</strong>ed<br />

only 10 trained surgeons for a population of 5.3 million 25 . Any<br />

approach to human resources must strongly consider task shifting<br />

as a means to provide the necessary number of surgical<br />

caregivers, at least over the short term 58-75 . While there remains<br />

some controversy regarding the use of non-physician clinicians,<br />

especially for surgery, these health workers may be found in at<br />

least 25 of 47 Sub Saharan African countries 58 . While the training<br />

is shorter and less costly than for physicians (and is based on the<br />

local disease burden), the curriculum and scope of practice have<br />

not been standardized. Non-physician caregivers perform<br />

selected surgical services in Ethiopia, Angola, Ghana, Kenya,<br />

Mozambique, Tanzania, Malawi, and Uganda. Several reports<br />

have suggested that alternate cadres of health worker can safely<br />

and successfully perform caesarian section, as evidenced in<br />

Mozambique, Malawi and Tanzania 61-64 . Orthopaedic services have<br />

been shiften to non-surgeons effectively in Uganda and Malawi 65-<br />

67<br />

. Malawi has nine orthopaedic surgeons for a population of<br />

approximately 27 million, and Orthopaedic Clinical Officers (OCO)<br />

provide all of the district hospital level orthopaedic services for the<br />

country, under remote supervision from the few orthopaedic<br />

surgeons 65,66 . A diploma is offered after eighteen months of<br />

training, and core competencies include the treatment of<br />

musculoskeletal infections, burns, clubfoot, fractures and<br />

dislocations, and amputations 66 . Of 117 caregivers trained in this<br />

programme, only 11% have retired or relocated 66 . Uganda also<br />

utilizes 200 orthopaedic officers, as only 23 orthopaedic surgeons<br />

are available for a population of 28 million 67 . Another approach is<br />

the training of a “rural surgeon”; a pilot project has been initiated<br />

in India, and medical school graduates enroll in a 3 year training<br />

programme which focuses on competency in a finite number of<br />

common surgical procedures drawn from all of the surgical<br />

subspecialties, adapted to the local disease burden 74,75 . These<br />

individuals are typically recruited from a rural environment, and<br />

plan to practice in a rural environment. Further study will be<br />

required to evaluate the utility of this approach.<br />

Integration of surgical services in primary healthcare<br />

reforms<br />

The most recent World Health Report 23 focuses on how primary<br />

health care reforms may strengthen health systems and provide<br />

universal access to quality health services. Within this scheme, the<br />

primary care team serves to coordinate the delivery of health<br />

services, directly interfacing with communities and individuals.<br />

Despite the emphasis on primary care and preventive medicine,<br />

and the suggestion that hospital based services should be<br />

reduced, surgical care is recognized as an important component<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 113


Innovation and clinical specialities: surgery<br />

of the health system 23 .<br />

We feel that “essential” surgical care should be viewed as<br />

primary prevention of death and disability, and that the integration<br />

of surgical services at the district level in LMICs will strengthen<br />

population based health care. How can we reduce maternal<br />

mortality if access to caesarian section cannot be provided, or<br />

improve childhood survival without better care for the injured?<br />

Examples include not only the capacity to perform selected<br />

procedures such as cesaerean section, laparotomy, repair of a<br />

strangulated hernia, irrigation and debridement, or conservative<br />

management for fractures/dislocations, but also the ability to care<br />

for surgical diseases which might not require a procedure, such as<br />

closed head injury or blunt abdominal trauma. The vision of a<br />

comprehensive, horizontal approach must be emphasized, as<br />

illustrated by the WHO’s Emergency and Essential Surgical Care<br />

project (EESC) 4,6,76-79 , a diverse educational programme which has<br />

been introduced in 33 countries. In addition, the Global Initiative<br />

for Emergency and Essential Surgical Care (GIEESC) was<br />

launched in 2005, and represents the first coordinated effort to<br />

address global disparities in surgical care 79 .<br />

Integrating surgery and anaesthesia at the district level within<br />

the context of primary health care reforms will require commitment<br />

from multiple stakeholders, including governments and their<br />

ministries of health, funding agencies, non-governmental<br />

organizations, academic institutions, organizations outside the<br />

health sector, as well as community leaders and individual.<br />

Adequate resources must be allocated to upgrade and maintain<br />

capacity of the district health system (including surgery and<br />

anaesthesia), and mechanisms to train and retain health workers<br />

must be developed. Strengthening the deliver of essential surgical<br />

services will improve the capacity to deliver other hospital based<br />

services, enhance population based health care, and contribute to<br />

achieving the Millennium Development Goals. ❏<br />

Wipak Medical – Steriking ® specialized<br />

packaging for hospital sterilization<br />

ARTICLE BY WIPAK<br />

Wipak manufactures specialized packaging for hospital sterilization, including<br />

sterilization packaging materials, sterilization monitoring products and sealing<br />

equipment and accessory products for sterile supplies.<br />

STERIKING ® CLEAN PEEL, MULTI-X FILMS<br />

Steriking ® Clean Peel range of see-through packaging, thanks to a<br />

unique Multi-X film, provides for a reliable processing and safe<br />

presentation of a packed item. In the modern multilayer film<br />

technology, featured in the Steriking ® Multi-X films, it is possible to<br />

produce steam sterilizable plastic films that resist high<br />

temperatures but have high tensile strength. These films facilitate<br />

strong sealing properties against medical papers, preventing<br />

possible packaging bursting failure. The low incidence of bursting<br />

and tearing minimizes resterilization load and costs.<br />

The two major sources of packaging failure are bursting during<br />

sterilization and/or film tear or paper shear when opening a<br />

package. Bursting of a pack can be caused e.g. by inadequate<br />

seal strength. The cause for tearing and shearing can be a low<br />

internal tensile strength of the film or paper. When exposed to heat<br />

upon sealing and sterilization processes, most plastic materials<br />

crystallize. This crystallization makes the material more brittle, thus<br />

reducing the tensile strength of the film.<br />

Figure 2: Sterilization packs<br />

STERILIZATION PACKS<br />

A well-designed and correctly used sterilization pack provides for<br />

effective sterilization and safe handling and storage of all items<br />

until the moment they are used. A pack must remain sealed<br />

against bacteria and facilitate aseptic presentation of the<br />

packaged product. The Steriking ® sterilization packaging are<br />

developed and designed to ensure optimal reliability of use in<br />

hospitals and other health care institutions. The sterile state of<br />

medical device, which is achieved through sterilization, is<br />

maintained with the help of an appropriate packaging. The design,<br />

materials and manufacture of the packaging materials have to be<br />

compatible with the medical device to be packed, the handling<br />

processes of the medical device, the sterilization method to be<br />

used, the labelling systems and distribution and storage<br />

conditions as well.<br />

AN UNIQUE CONTROL SHEET FOR SEAL QUALITY TEST<br />

Where medical devices are packed for sterilization the user is<br />

responsible for assuring the performance of the final closing seal<br />

of a package. Steriking ® Seal Control is designed for operational<br />

qualification of the sealing process. The critical paremeters of a<br />

sealing process are temperature, time and pressure. Under the<br />

new standard ISO 11607-2: 2006 the following qualities of the seal<br />

should be controlled: intact seal for a specified width, channels or<br />

open seals, punctures or tears and material delaminating or<br />

splitting. The Seal Control sheet accurately simulates see-through<br />

peel packages and provides users a practical tool for validation<br />

and <strong>document</strong>ation processes. It is exclusive designed and<br />

patented by Wipak.<br />

range is suitable for sterilization in steam and gas processes. The<br />

identification of packed instruments is easy because of the<br />

transparent plastic film. Thanks to the coloured film, it is possible<br />

to visually control the seal integrity.<br />

Innovations in patient care: infection control<br />

Surgical Site Infections (SSIs),<br />

antimicrobial agents, universal<br />

precautions and post-exposure<br />

prophylaxis<br />

ARTICLE BY JONATHAN SAMUEL,<br />

University of North Carolina, School of Medicine, Chapel Hill, North Carolina<br />

WAKISA MULWAFU, (PICTURED)<br />

Queen Elizabeth Central <strong>Hospital</strong>, Blantyre, Malawi<br />

SSIs represent a major cause of morbidity in surgical patients, affecting only around 2% of patients with<br />

clean cases, but upwards of 15-20% of patients undergoing contaminated cases. This article sets out to<br />

show the best ways of dealing with surgical site infections and makes specific recommendations for the<br />

best ways of treating SSIs.<br />

Awound is defined by the Center for Disease Control (CDC)<br />

as an interruption or break in the continuity of the external<br />

surface of the body or the surface of an internal organ,<br />

caused by surgical or other forms of injury or trauma. A surgical<br />

site infection (SSI) is clinically defined as presence of pain at a<br />

surgically created wound, which is accompanied by erythema,<br />

induration and local tenderness or presence of purulent discharge<br />

at wound site 1 . SSIs are not a modern phenomenon. As early as<br />

14-37AD there is <strong>document</strong>ary evidence that Cornelius Celsus (a<br />

Roman physician) described the four principal signs of<br />

inflammation and used “antiseptic” solutions. Another Roman<br />

physician, Claudius Galen (130-200 AD) had such an influence on<br />

the management of wounds that he is still thought of by many<br />

today as the “father of surgery”.<br />

Surgeons encounter wound infections in two major ways:<br />

patients present with an infection that requires surgical treatment,<br />

like drainage of an abscess; or infection complicates a surgical<br />

procedure, e.g. SSI. This problem was almost universal prior to the<br />

development of aseptic surgery in the last century but, in spite of<br />

our more sophisticated understanding of the nature of infection<br />

and an arsenal of antimicrobial agents, SSI still remains a major<br />

surgical problem today.<br />

SSIs have a significant impact on patients, increasing length of<br />

hospital stay, contributing to overuse of hospital stay, contributing<br />

to an overuse of antibiotics and increased associated costs, and<br />

contributing to increased mortality 2 .<br />

SSIs are common, comprising about 12% of all hospitalacquired<br />

infections. The rate of infection varies depending on the<br />

type of surgery undertaken. Especially high rates are associated<br />

with contaminated surgery, such as colorectal surgery or delayed<br />

surgery to traumatic wounds.<br />

Aetiology of SSIs<br />

SSIs are caused by the deposition and multiplication of<br />

microorganisms in the surgical site of a susceptible host. There are<br />

a number of ways microorganisms colonize and cause infection,<br />

including: a) direct contact – either from another patient, transfer<br />

from surgical equipment or the hands of the hospital staff; b)<br />

airborne dispersal – surrounding air contaminated with microorganisms<br />

that deposit onto the wound; and c) self-contamination<br />

(also known as endogenous infection) – physical migration of the<br />

patient’s own normal flora which are present on the skin, mucous<br />

membranes or gastrointestinal tract to the surgical site. Most<br />

surgical infection is due to bacterial and, more rarely, fungal<br />

infection. Viruses, such as human immunodeficiency virus (HIV)<br />

and the hepatitis B and C viruses are important to surgeons<br />

because they may contract these diseases from their patients.<br />

Due care has to be taken when managing such patients and<br />

infection significantly alters the host response to other diseases.<br />

The commonest organism causing SSI is Staphylococcus<br />

aureus. Other common causative organisms include other Gramnegative<br />

aerobes, Streptococcus spp. and anaerobes. A study by<br />

Erickson et al. in Tanzania showed that S. aureus was the most<br />

common isolate (n=22), followed by E. coli (n=12) and Klebsiella<br />

120 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovations in patient care: infection control<br />

spp. (n=12) 2 . In another observational study in Tanzania, the overall<br />

rate of SSI was 24% among all surgical disciplines; wound<br />

classification associated with infection (dirty-infected wounds) had<br />

a risk ratio of 2.8 compared to clean wounds 3 . Overall, 144 of the<br />

618 patients studied developed SSIs, with the most common<br />

isolates being S. aureus (37%), E. coli (11%), and Enterococcus<br />

spp. (5%). Especially concerning was the isolation of one strain of<br />

methicillin-resistant S. aureus (MRSA) and three isolates of<br />

vancomycin-resistant Enterococcus. Of the patients with SSIs in<br />

the study, 35% had cultures that yielded no growth or “no clinically<br />

significant organism.” The authors do not specifically mention<br />

whether anaerobic cultures were done, and no obligate anaerobes<br />

were identified, so the high rate of negative cultures may be in part<br />

due to failure to identify obligate anaerobes.<br />

Risk factors associated with SSIs<br />

The likelihood of developing an SSI is influenced by a number of<br />

factors. These factors fall into four major groups, which are:<br />

patient factors, anaesthetic factors, wound status, and surgeon<br />

factors.<br />

Patient factors<br />

General patient characteristics that play a role in SSI include:<br />

immunosuppression, malnutrition, endocrine & metabolic<br />

disorders, obesity, age (young and elderly), malignant disease and<br />

others. All these factors have their influence by lowering host<br />

immunity to various infections.<br />

Given the high prevalence of HIV among patients in developing<br />

countries, the impact of HIV on surgical outcomes is a topic of<br />

considerable interest. For example, HIV infection leads to a lower<br />

rate of both skin graft survival (69% vs. 22%) 4 , and overall patient<br />

survival among burn victims (for 21-30% burns: 100% mortality<br />

versus 50% mortality in HIV negative patients) 5 . Among HIV<br />

positive patients undergoing anorectal procedures, wound healing<br />

is poor 6,7 .<br />

A considerable body of research exists on the topic of surgical<br />

site infections and HIV as well. In orthopaedic trauma patients, the<br />

risk of postoperative infection is considerably higher in HIV positive<br />

individuals (16.7% versus 5.4%) 8 , though in elective orthopaedic<br />

cases with intact skin and use of implants, the rate of infection<br />

clots in the wound space and prevention of third spaces by tissue<br />

re-approximation.<br />

Prevention of SSIs<br />

Prevention is always better than a cure, and thus a careful<br />

assessment of risks related to SSIs is paramount. The goal of SSI<br />

management is to prevent or minimise the risk through careful<br />

planning.<br />

The following factors or methods external to the patient are<br />

critical to preventing SSIs: a) Theatre environment and care of<br />

instruments; maintenance of positive pressure ventilation of<br />

operating theatre, laminar airflow in high risk areas, and<br />

sterilisation of surgical instruments, sutures etc. according to<br />

guidelines, and b) Surgical team members educated in aseptic<br />

technique; staff with infections excluded from duty and scrubbing<br />

up followed by appropriate sterile attire.<br />

The following section outlines the evidence regarding hair<br />

removal, preparation of the sterile field, and wound closure<br />

technique. Prophylactic antibiotic use is discussed in section 6.<br />

Decisions regarding hair removal<br />

Hair removal is commonly performed prior to surgery, yet both the<br />

Centers for Disease Control and Prevention (CDC) and the<br />

Norwegian Centre for Health Technology Assessment recommend<br />

against hair removal 14 . The CDC recommends that, if performed,<br />

hair removal should be done by clipping or use of a depilatory<br />

cream, rather than by razor. A recent Cochrane Database of<br />

Systematic Reviews identified 11 studies that met criteria for<br />

inclusion in a meta-analysis of hair removal and infections; 3 of<br />

these studies compared shaving with clipping and found that<br />

shaving increased surgical site infections (relative risk 2.02, 95%<br />

confidence interval 1.21 to 3.36). Furthermore, shaving versus<br />

clipping leads to more skin trauma even under ideal conditions,<br />

providing further evidence that shaving should be avoided 15 .<br />

There were no studies meeting inclusion criteria that compared<br />

clipping of hair to no hair removal. Two studies compared shaving<br />

with no hair removal, and found that shaving increased infection<br />

(relative risk 1.59). However there were relatively few subjects in<br />

these two studies and hence the conclusion did not reach<br />

statistical significance.<br />

Evidence from within Africa supports the CDC recommendation<br />

against hair removal. Adeleye et al. recently reported their<br />

experience with 17 cranial procedures on black Africans, in which<br />

all of the fields were non-shaved, and reported no serious<br />

complications over a 2 to 6 month follow-up 16 .<br />

In conclusion, if hair is to be removed at all, it should be done by<br />

clipping and not by shaving. Furthermore, hair should not routinely<br />

be removed except in cases where the presence of hair interferes<br />

with the technical aspects of the surgery, which is a judgment that<br />

is best left to the operating surgeon within the context of these<br />

recommendations.<br />

Preparation of the surgical field<br />

Two factors relate to the surgical field – the choice of skin<br />

preparation, and the method of draping. In developing countries,<br />

the choice of drapes has been limited due to cost constraints,<br />

whereas in developed countries, sterile, adhesive iodineimpregnated<br />

drapes (commonly known as Ioban) are available.<br />

These adhesive drapes are placed over the skin after preparation<br />

and application of standard side drapes. However, this practice<br />

has demonstrated no benefit in randomized controlled trials.<br />

Furthermore, adhesive drapes without iodine increase SSI rates<br />

(relative risk 1.23, p=0.03) 17 . Thus the avoidance of adhesive<br />

drapes as an adjunct to standard cloth drapes is best avoided.<br />

Several methods of skin preparation are available, including<br />

chlorhexidine, iodine, spirit, and over-the-counter soap. Bibbo et<br />

al. compared chlorhexidine and isopropyl alcohol to povidoneiodine<br />

in a randomized of 127 patients undergoing foot surgery<br />

and found that chlorhexidine preparation resulted in a lower rate of<br />

culture-positive skin swabs (38% versus 79%) 18 . Chlorhexidine, an<br />

antiseptic solution that has been used worldwide since the 1950s,<br />

is a safe and effective product with broad antiseptic activity.<br />

Chlorhexidine gluconate is a water soluble, cationic biguanide that<br />

binds to the negatively charged bacterial cell wall, altering the<br />

bacterial cell osmotic equilibrium and is available in a variety of<br />

concentrations (0.5%–4%) and formulations (with and without<br />

isopropyl alcohol or ethanol). Chlorhexidine (0.05% solution) has<br />

broad activity against gram-positive and gram negative bacteria,<br />

facultative anaerobes and aerobes, yeasts, and some lipidenveloped<br />

viruses, including HIV. Chlorhexidine is not sporicidal 19 .<br />

Meier et al., recognizing the scarcity at times of conventional<br />

skin preparation solutions, compared the use of over-the-counter<br />

soap followed by methylated spirit, to the use of iodine 20 . The<br />

study randomized 200 patients undergoing elective inguinal hernia<br />

repair in Nigeria. In group 1, the subject’s skin was prepared by<br />

scrubbing with soap and water, blotting with a sterile towel, and<br />

applying spirit. In group 2, skin was prepared by scrubbing with<br />

povidone-iodine then blotting with a sterile towel and applying<br />

povidone-iodine paint. There was no difference in surgical site<br />

infections between groups 1 and 2 (5.1% versus 5.9%,<br />

respectively).<br />

To this date, no studies have compared using soap and spirit<br />

versus chlorhexidine. Thus the current evidence supports the use<br />

of chlorhexidine for preparation of the surgical site. If chlorhexidine<br />

is not available, scrubbing with soap followed by painting with<br />

spirit (70% alcohol/30% water) appears equally efficacious as<br />

scrubbing and painting with povidone-iodine.<br />

Wound closure techniques and use of drains<br />

There is little disagreement that clean wounds should be closed<br />

primarily. However, the choice of whether to close primarily or<br />

leave open, contaminated and clean-contaminated wounds is not<br />

as straightforward. If a wound is not closed primarily (closed at the<br />

time of surgery), it can be left open to heal by secondary intent, or<br />

evaluated for closure at a later date (delayed primary closure, or<br />

DPC). DPC of a surgical wound involves placing sterile dressing<br />

over the wound at the conclusion of the case, and then removing<br />

the dressing usually several days later. If the wound bed appears<br />

clean and without devitalized tissue, the wound is then closed with<br />

sutures.<br />

One prospective randomized study from Tanzania found that the<br />

rate of infection was higher when clean-contaminated or<br />

contaminated wounds were left open, as opposed to closed<br />

(30.2% versus 2.1%) 1 . It must be noted that those subjects in the<br />

group whose wounds were left open were heterogeneous, and<br />

included a combination of delayed primary closure (DPC) and<br />

secondary healing techniques. Marion et al. conducted a metaanalysis<br />

of primary versus DPC in complicated appendicitis, and<br />

122 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovations in patient care: infection control<br />

found similar results, with a lower rate of infection in those wounds<br />

closed primarily (relative risk 0.64, 95% confidence interval 0.46 to<br />

0.91) 21 .<br />

The one exception in which DPC might be advisable is in the<br />

management of traumatic wounds. For DPC of traumatic wounds,<br />

the same general principles for DPC of surgical wounds apply: no<br />

wound should be closed if grossly contaminated, and any<br />

devitalized tissue should first be debrided. The management of<br />

neglected or chronic wounds by DPC is more complicated. The<br />

<strong>International</strong> Committee of the Red Cross provides a good<br />

overview of DPC in traumatic, neglected, and contaminated<br />

wounds 22 .<br />

Decisions surrounding placement of a surgical drain is beyond<br />

the scope of this review. However, in most cases the routine use<br />

of surgical drains should be discouraged, as is discussed in an<br />

excellent review by Schein 23 . Schein does note that select<br />

situations may be appropriate for drain placement, including noncollapsible<br />

abscesses (rare), high prediction of fluid leakage (bile,<br />

pancreatic juice, or urine), or drainage for a short duration of an<br />

“oozy” surface. One study compared the use of post-mastectomy<br />

drains for 4 days or 10 days, and found a significantly higher rate<br />

of infection among those drains left in place for 10 days (9.5%<br />

versus 2.2%) 24 , lending support to Schein’s recommendation of a<br />

short duration of drainage.<br />

Treatment of surgical site infections<br />

The following section outlines the diagnosis and surgical treatment<br />

of SSIs. Use of antibiotics is discussed in section 6, and is<br />

secondary to adequate drainage, discussed below.<br />

Diagnostic criteria<br />

An SSI is defined by both clinical and microbiological<br />

examinations. The isolation of bacteria from the wound alone is<br />

not diagnostic for an SSI without at least clinical evidence of<br />

infection (redness, localised swelling, pain or tenderness, purulent<br />

discharge, relative warmth to the touch). Often, SSIs are<br />

diagnosed and treated based on a constellation of signs and<br />

symptoms. However, samples from the wound can also be taken<br />

for culture. Pus or, if appropriate, a tissue biopsy is preferred over<br />

simple wound swabs. In patients where bacteraemia or sepsis is<br />

suspected, blood cultures should also be taken.<br />

Drainage<br />

“Never let the sun set on an abscess.” This frequently quoted<br />

surgical adage emphasizes the critical importance of timely<br />

diagnosis and treatment of SSIs. Though some SSIs may be<br />

limited to cellulitis, one should have a low threshold for incision and<br />

drainage, or reopening, either a portion or all of the incision, to<br />

drain pus if examination suggests the infection is more then<br />

cellulitis.<br />

Special note must also be made of necrotizing fasciitis, which<br />

can occur as a SSI. Signs that suggest necrotizing fasciitis<br />

include:<br />

✚ wounds with early drainage of clear brown fluid (“dishwater<br />

drainage”);<br />

✚ wounds in which the subcutaneous fat has a dark brown<br />

discoloration;<br />

✚ wounds in which normally adherent tissue planes separate<br />

easily;<br />

✚ wounds in which subcutaneous vessel thrombosis is present.<br />

Any of these signs or the presence of systemic toxicity, suggest<br />

a serious infection, and immediate debridement of all infected<br />

tissue is the mainstay of treatment. This may require debridement<br />

of skin, subcutaneous fat, and possibly muscle. (See Surgery in<br />

Africa, October 2005: Soft-tissue infections)<br />

Antibiotics and SSIs<br />

The goals of antibiotic prophylaxis are to achieve inhibitory<br />

antibiotic levels at incision and throughout the procedure in an<br />

effort to decrease the likelihood of developing a SSI. Antibiotics<br />

can also play an important role in the treatment of SSIs.<br />

Antibiotics for prophylaxis of SSIs<br />

Animal studies have shown that antibiotic prophylaxis is most<br />

effective in preventing post-surgical infections when administered<br />

before the start of surgery, and pharmacokinetic data suggest<br />

administration as near the time of incision as possible. Classen et<br />

al., in a prospective observational study, monitored the timing of<br />

antibiotic prophylaxis in 2847 patients in “clean” or “clean<br />

contaminated” surgery. Using a step-wise logistic regression<br />

model, they found that preoperative antibiotics within two hours of<br />

incision had the lowest rate of infection as compared to antibiotics<br />

given after incision or earlier than two hours prior 25 .<br />

In addition to being given preoperatively, prophylactic antibiotics<br />

should not be continued postoperatively. A five-month prospective<br />

survey of surgical-site infections (SSI) conducted in the<br />

department of general surgery at Kilimanjaro Christian Medical<br />

Center, Tanzania by Eriksen et al., showed that 77 (19.4%) of the<br />

397 patients studied developed SSI 2 . Twenty-eight (36.4%) of<br />

these infections were apparent only after discharge from hospital.<br />

A surprising eighty-seven percent of the patients who developed<br />

SSI had received antibiotics, the majority having received the<br />

antibiotics for several days. Such a practice is contrary to the<br />

current recommendation of a single preoperative dose, and<br />

prolonged inappropriate use of broad-spectrum antibiotics may<br />

contribute to increased emergence of resistance.<br />

The type of surgery (clean, clean/contaminated, contaminated,<br />

or dirty) (see Table 1) also impacts the role of antibiotic prophylaxis.<br />

An understanding of this classification, as well as knowledge of<br />

recommendations for specific procedures, is invaluable in making<br />

an appropriate choice regarding antibiotic prophylaxis. Antibiotic<br />

administration in dirty cases is not considered prophylactic as<br />

these cases represent treatment of infection rather than<br />

prophylaxis.<br />

Controversy exists regarding the use of antibiotic prophylaxis for<br />

clean cases. When antibiotic prophylaxis is given, the agent<br />

should target S. aureus, the most common organism causing SSIs<br />

in clean cases; cefazolin is a good choice 26 . When bone is incised,<br />

the use of prophylactic antibiotics is clearly recommended 27 . A<br />

good choice in this situation, or for cardiothoracic or vascular<br />

surgery, is cefazolin or cefuroxime (or clindamycin or vancomycin<br />

for penicillin allergic) 26 . For general surgical clean cases, the<br />

decision is less clear. A Cochrane Database of Systematic<br />

Reviews examined the use of prophylactic antibiotics prior to<br />

hernia surgery, and found that infection rates were lower with use<br />

of antibiotics (2.9% versus 3.9%) but concluded that “antibiotic<br />

prophylaxis for elective inguinal hernia repair cannot be universally<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 123


Innovations in patient care: infection control<br />

recommended” because of overall low infection rates, a high<br />

number needed to treat, and a lack of a large, randomized<br />

controlled trial to prove efficacy 28 . Similarly, Osuigwe et al. studied<br />

the use of prophylactic antibiotics for paediatric surgery in a<br />

prospective, randomized, double-blind study of 289 children at a<br />

teaching hospital in Nigeria 29 . Patients were randomly assigned to<br />

receive either doses of ampicillin/cloxacillin (Ampliclox) with vitamin<br />

B (Group A, treatment group), or vitamin B only (Group B, placebo<br />

group). The doses were begun at induction and continued for five<br />

days postoperatively. Patients were evaluated for wound infection<br />

at postoperative day 5, and then again at postoperative day 7 to<br />

10 during suture removal. Wound infection was defined as the<br />

presence of erythema, induration, or discharge. Group A had a<br />

4.3% infection rate compared to 5% in group B, a difference that<br />

was not statistically significant.<br />

For clean-contaminated and contaminated cases, antibiotic<br />

prophylaxis is recommended. Colorectal surgery is the most<br />

thoroughly studied type of procedure in this category, and as such<br />

most recommendations are based on studies involving colorectal<br />

surgery. The most commonly encountered organism in cleancontaminated<br />

and contaminated SSIs is still S. aureus, though<br />

other aerobic as well as anaerobic bacteria are also culprits 30 . As<br />

such, prophylaxis should be broader than that used for clean<br />

cases. Song et al. reviewed all randomized controlled trials of<br />

antibiotic prophylaxis in colorectal surgery 31 . Four of these studies<br />

compared antibiotic regimens to no antibiotics and showed a<br />

convincing benefit of prophylactic antibiotics (odds ratio 0.24,<br />

95% confidence interval 0.13 to 0.43). Further analysis revealed<br />

that the most efficacious regimens include coverage against both<br />

aerobic and anaerobic organisms (such as a 2nd or 3rd generation<br />

cephalosporin, or gentamicin in combination with metronidazole),<br />

and cited certain regimens inadequate (metronidazole alone,<br />

doxycycline alone, piperacillin alone) 32 . Though data from Africa is<br />

limited, differences in efficacy between various 2nd and 3rd<br />

generation cephalosporins appear negligible 33 , and choice<br />

prophylaxis with a single-agent 2nd or 3rd generation<br />

cephalosporin can probably be dictated by availability or cost. For<br />

penicillin-allergic patients, clindamycin combined with gentamicin,<br />

aztreonam, or ciprofloxacin, or metronidazole combined with<br />

gentamicin or ciprofloxacin are adequate choices 26 .<br />

Antibiotics for treatment of SSIs<br />

Empiric treatment of an SSI after clean cases should be primarily<br />

directed against S. aureus. Clean-contaminated, contaminated,<br />

and dirty cases require broader empiric coverage to include both<br />

aerobic and anaerobic bacteria. Choices of empiric therapy,<br />

against SSIs suspected of being caused by S. aureus, such as<br />

SSIs after clean cases, include cloxacillin or in penicillin-allergic<br />

patients, clindamycin. For SSIs after clean-contaminated,<br />

contaminated or dirty cases, a second- or third-generation<br />

Cephalosporin (such as cefuroxime or ceftriaxone), metronidazole<br />

with gentamicin, or amoxicillin/clavulanate, are all reasonable<br />

choices that will provide aerobic and anaerobic coverage.<br />

It is also important to take note that in many surgical operations,<br />

patients will have previously received antibiotic prophylaxis.<br />

Prophylaxis can affect the flora and thus the cause of any<br />

subsequent infection. One study of antibiotic prophylaxis for<br />

cardiac surgery compared vancomycin to cefazolin, and found<br />

that SSIs in those receiving cefazolin were more likely to be<br />

important to determine the nature of any prior antibiotic therapy; a<br />

prudent approach is to choose a different regimen that the one<br />

used for prophylaxis at the time of surgery.<br />

Lastly, it should be re-emphasized that antibiotic administration<br />

for SSIs is secondary to the cornerstone of treatment—which is<br />

adequate drainage of the infection. Additionally, if antibiotic<br />

sensitivities are identified, it may be necessary to tailor antibiotics<br />

to the specific strains. Many surgeons use topical agents such as<br />

hydrogen peroxide, 2% acetic acid, or Dakin’s solution (0.5%<br />

sodium hypochlorite), but evidence in support of this is scant. A<br />

review of the evidence regarding Dakin’s solution, for example,<br />

found only three small prospective studies and concluded that<br />

there was no benefit to its use 35 . More important is the frequency<br />

of dressing changes when managing SSIs; dressings should be<br />

changed if they appear soiled or are foul-smelling, and must be<br />

changed no less frequently than once daily. Lastly, one should not<br />

forget to emphasize the importance of hand hygiene to the<br />

guardian, or any others involved in the care of the patient, which<br />

minimizes cross-contamination.<br />

Universal precautions and post-exposure prophylaxis<br />

Universal precautions mandate that health care providers assume<br />

all patients carry a transmissible infectious disease (such as viral<br />

hepatitis or HIV), and maintain precautions against contracting<br />

such infections. The nature of personal protective equipment is<br />

situation-dependent, and may include gloves, eye protection, a<br />

protective gown and/or boots, or a mask. Bodily fluids, including<br />

blood and saliva, as well as airborne particles, are considered an<br />

exposure risk. Testing all patients to identify individuals infected<br />

with transmissible diseases is not feasible, and thus universal<br />

precautions are required 36 .<br />

In addition to universal precautions, pre-exposure vaccination<br />

against hepatitis B is recommended. All health care workers<br />

potentially coming in to contact with bodily fluids should be<br />

vaccinated against hepatitis B, which is given as a series of three<br />

intramuscular doses. Despite the importance of hepatitis B<br />

vaccination, many health care workers are not vaccinated due to<br />

either not being aware of the vaccine’s efficacy, or being unable to<br />

afford the series of vaccinations 37 .<br />

HIV and hepatitis C pose risks to health care providers, and to<br />

this date there are no vaccinations available for pre-exposure<br />

prophylaxis. Therefore prevention relies solely on universal<br />

precautions and safe practices, such as not recapping used<br />

needles, using sharps containers appropriately, and properly<br />

124 <strong>Hospital</strong> and Healthcare Innovation Book 2009/2010


Innovations in patient care: infection control<br />

passing sharp instruments in theatre (by a sharps container, or<br />

using verbal communication between the surgeon and the scrub<br />

nurse).<br />

To this date, there are no known cases of transmission of HIV<br />

from a patient to a health care provider in the operating room.<br />

However there are at least 57 <strong>document</strong>ed cases of transmission<br />

to health care providers in settings outside of the operating room 38 .<br />

Hepatitis C poses a more serious risk of transmission, which is<br />

estimated to be 2% if the patient is infected with hepatitis C, and<br />

the health care provider as been stuck with a hollow needle 39 .<br />

After unintentional exposure, the site should be copiously<br />

washed, and consideration must be given to post-exposure<br />

prophylaxis against HIV. If possible, the patient should be tested<br />

for HIV. Factors influencing the choice for or against HIV post<br />

exposure prophylaxis include the type of exposure, whether the<br />

status of the patient is known at the time of exposure, and the<br />

availability of post exposure prophylaxis. The overall risk of<br />

transmission from a needle stick when the patient is HIV positive<br />

is estimated at 0.3%; high risk occupational exposure from an HIV<br />

positive patient is defined as a deep puncture with a hollow<br />

needle, a needle that is visibly contaminated, large bore needle,<br />

needle that was place directly in an artery or vein, high viral load of<br />

the patient, or a patient with end-stage disease 40 . Post-exposure<br />

prophylaxis should continue for 28 days and include both a<br />

nucleotide reverse transcriptase inhibitor (NRTI) and a protease<br />

inhibitor (PI); in the United Kingdom, the recommended regimen is<br />

now Combivir (lamivudine and zidovudine, both NRTIs) with<br />

lopinavir and ritonavir (PIs; supplied in combination as Kaletra)<br />

(Table 2).<br />

Summary of recommendations<br />

In conclusion, SSIs represent a major cause of morbidity in<br />

surgical patients, affecting only around 2% of patients with clean<br />

cases, but upwards of 15-20% of patients undergoing<br />

contaminated cases.<br />

1. To limit the chance of SSIs, one should treat any endocrine or<br />

metabolic disorders in the patient, and optimize nutritional<br />

status.<br />

2. Preoperative antibiotics should be given for clean-contaminated<br />

and contaminated cases (second or third generation<br />

cephalosporin). For clean cases, the evidence is mixed, and if<br />

given the best choice is a first generation cephalosporin. The<br />

antibiotic should be given before incision, but no longer than 60<br />

minutes before, and should not be continued for more than 24<br />

hours postoperatively. Antibiotics for dirty cases represent<br />

treatment of infection and thus are not considered prophylaxis.<br />

3. Body hair need not be removed, and if the surgeon chooses to<br />

remove hair, it should be done by use of clippers or a depilatory<br />

agent; shaving causes an increased chance of wound infections<br />

and must be avoided.<br />

4. Chlorhexidine is the best skin preparation agent. Soap followed<br />

by iodine, or 70% alcohol followed by iodone are the next best<br />

alternatives.<br />

5. Intraoperatively, patients should retain normothermia,<br />

normoglycemia, and adequate perfusion and oxygenation. The<br />

surgeon should minimize tissue devitalisation, adhere to sterile<br />

technique, avoid hematoma formation, and close potential<br />

spaces.<br />

6. Evidence supports closing primarily all wounds, and avoiding<br />

drain placement, or if used, such as in breast surgery, not<br />

leaving drains in post-operatively any longer than necessary.<br />

7. If one suspects an SSI (redness, localised swelling, pain or<br />

tenderness, purulent discharge, relative warmth to the touch),<br />

maintain a low threshold for opening the wound which is the<br />

primary treatment. Antibiotics are secondary to adequate<br />

drainage. There are a number of reasonable choices for treating<br />

SSIs, and the choice of an agent should be dictated by culture<br />

results when possible.<br />

8. Surgeons should be familiar with the risks of transmission of<br />

HIV, and the indications for and choices of post-exposure<br />

prophylaxis. All surgeons should be vaccinated against hepatitis<br />

B virus. ❏<br />

Innovation in patient care: patient handling<br />

Have we created an alternative MSD<br />

risk from a reliance on hoisting<br />

solutions? An academic review of<br />

patient handling research<br />

ARTICLE BY AUTHOR M FRAY<br />

Research Fellow, Healthcare Ergonomics and Patient Safety Research Unit, Department of Human Sciences, Loughborough University, UK<br />

Many hospitals employ systems and personnel to reduce the effects of patient handling activities. Research has<br />

found limited evidence for the benefits of patient handling interventions and poor levels of evidence for the<br />

reduction of work-related MSDs in the healthcare setting. Historically the reduction of MSDs has been the primary<br />

purpose of patient handling interventions but other benefits have been identified. This paper describes the range<br />

of outcomes that have been identified in published research. Describes the type of intervention strategy that gives<br />

best results and suggests that hospitals and healthcare providers need to consider appropriate audit systems to<br />

collect suitable data to prove the success of their management systems.<br />

There is clear evidence to show that the size of patients entering<br />

healthcare is increasing in the western world.<br />

Some systems have been developed to help reduce the risks<br />

of managing the movement of larger people (Muir and Archer-Heese,<br />

2009). The focus of risk reduction in patient handling has rightly been<br />

on the reduction of lifting injuries as a priority. Given the development<br />

of a wide range of lifting equipment to assist with the movement of<br />

larger people the consensus is that we are in a relatively well controlled<br />

risk position. Evidence shows the provision of hoisting equipment<br />

reduces the risks of injury but the question raised in this review asks<br />

whether the risks are reduced enough? Recent studies have<br />

suggested that the push, pull and rotation forces required to move<br />

regular and large weight patients (Marras et al, 2008, Rice et al, 2009)<br />

exceed the much lower safe working limits for creating spinal damage<br />

from shear force in certain circumstances. This paper challenges the<br />

situations where current thinking would be to provide a mobile passive<br />

lifting hoist or mechanical means to transfer a larger adult.<br />

Literature analysis<br />

Patient handling<br />

A series of systematic reviews have failed to identify<br />

musculoskeletal disorder (MSD) reduction from patient handling<br />

interventions (Van Poppel, 2004, Bos et al, 2006, Amick et al<br />

2006, Haslam et al, 2006, Dawson et al, 2007, Martimo et al,<br />

2008). More inclusive reviews identify that other outcomes could<br />

be used to show success (Hignett et al 2003, Fray and Hignett<br />

2006, Fray and Hignett 2009). The volume of evidence for the<br />

reduction of known risk factors is growing and the development of<br />

multi-faceted ergonomics, equipment and education packages<br />

are showing improvements in practice (Nelson et al 2006, Collins<br />

et al 2004, Hignett 2003).<br />

Systems adopted in the UK were directed by the introduction of<br />

the Manual Handling Operations Regulations 1992 (HMSO 2004)<br />

and the subsequent development and support of both statutory<br />

providers and professional organisations. Though the countries of<br />

Europe all had the same EU directive the responses have not all<br />

been the same (Hignett et al, 2007). The North American systems<br />

and approaches have not had the pressure of national legislation<br />

but some state legislation has more recently been implemented<br />

from 2006 onwards.<br />

Risk reduction strategy<br />

The information and guidance contained in the <strong>document</strong>s relating<br />

to the management of health and safety in the workplace (HMSO<br />

1992 a,b,c) stated the need for a systematic assessment of<br />

workplace hazards, the reality of risk controls in patient handling is<br />

different.<br />

Research information identified that lifting people was the most<br />

easily identified risk (Owen and Garg 1989, 1990 and 1991, Takala<br />

and Kukkonen 1987, Zhang et al 1999, 2000 Menzel et al 2004)<br />

and the measure for lumbar compression was critical.<br />

Interestingly a comprehensive biomechanical study (Marras et al<br />

1999) using the lumbar motion monitor continued the evidence<br />

that compression values seriously exceeded the known<br />

recommended limits and should be rectified. It also showed that<br />

the methods for manual assistance also exceeded the safe limits<br />

for shear(anterior-posterior and/or lateral).<br />

The clear evidence presented related to lifting hazards, the<br />

reactive management style of the National Health Service and the<br />

chance of high return with simple process change lead to a large<br />

<strong>Hospital</strong> and Healthcare Innovation Book 2009/2010 127


Innovation in patient care: patient handling<br />

focus on the removal of hazardous lifting and transfer tasks with a<br />

lifting component. It has been the development of safer handling<br />

policies in their various definitions that have lead to much<br />

improvement in the management of patient handling risks. Proof of<br />

the success of developing multi-faceted interventions have mostly<br />

been recorded in studies from North America. Biomechanical and<br />

workload reductions have been recorded in a number of studies<br />

(Daynard et al 2001, Nelson et al, 2006, Ronald et al, 2002, Marras<br />

et al, 1999, Engst et al, 2005,). The cost benefits of such a process<br />

have also been recorded (Spiegel et al, 2002, Chhokar et al, 2005,<br />

Martin et al, 2009). Patient and staff perceptions improved with use<br />

of ceiling track systems (Alamgir et al 2009). These studies have<br />

also measured differences between the use of mobile hoists and<br />

ceiling track systems (Santaguida et al, 2005).<br />

Push-pull risks<br />

The focus of most of the biomechanical studies and workplace<br />

studies, above, have been on the lifting component and the<br />

resulting spinal compression loading. More specifically the<br />

concentration is on identification and then avoidance of any very<br />

high compression loading. This fails to address the more complex<br />

question of physical work done represented by force over time<br />

exposure. Daynard et al (2001) showed that when using handling<br />

aids and mechanical lifting the cumulative effort was increased, as<br />

the time taken was usually higher, but the peak forces were<br />

reduced. A recent study (Fray and Hignett, 2009) that restructures<br />

a lateral transfer task by the use of an innovative pressure reducing<br />

device showed significant savings in physical exposure by<br />

removing tasks and reducing the time taken to complete the<br />

transfer. This is the cumulative loading or exposure over time<br />

question that frequently taxes occupational injury research and<br />

prevention literature.<br />

Recent studies have, in addition, raised questions related to the<br />

potential problems of the pushing and pulling associated with<br />

healthcare tasks and in particular the use of hoists for patient<br />

transfers. Marras et al (2009) measured the spinal loads for a<br />

person manoeuvring a hoist across a fixed course and compared<br />

a ceiling tracked system with a floor based system. The key<br />

findings were that the patient weight affected the force needed with<br />

a floor based system but not a ceiling track system and the shear<br />

loading for the floor based system exceeded the safe working limit<br />

for shear during push tasks. Another study (Rice et al, 2009), which<br />

used hand held dynamometers to measure actual push pull forces<br />

for moving hoists, concurred with the relationships of weight to<br />

force for floor standing hoists and that floor standing hoists required<br />

more force than ceiling track systems.<br />

Importantly neither study investigated the forces required to<br />

obtain an ideal sitting or lying position or the complexities and<br />

postural loads of positioning the hoist sling. These two studies<br />

that measure the physical requirements of the solutions to<br />

handling issues may lead to further questions relating to some of<br />

our known risk reduction systems. It is worthy of note that these<br />

studies were completed with patients weighing up to 163kg and<br />

146kg respectively to identify the hazards of larger individuals.<br />

Population changes<br />

Recent observations have indicated that the size of western<br />

populations is increasing (DOH 2004, Heena 2005, Hedley et al<br />

2004). The growth in adult prevalence is matched by the increase<br />

in problems with increasing size and weight of infant populations<br />

(Stamatakis 2002, Hedley et al 2004). A systematic review (Baird<br />

et al 2005) showed there is agreement from many studies that<br />

childhood growth is a clear indicator for adult obesity. Given that<br />

a Cochrane review (Summerbell et al 2005) also indicated the<br />

general lack of success of intervention strategies for reducing<br />

population obesity for the long term and the desired weight in<br />

adult populations is also growing (Maynard et al 2006). Most of<br />

the evidence indicates to the providers of healthcare that the<br />

amount of overweight, obese and morbidly obese patients<br />

requiring healthcare interventions will increase over the<br />

foreseeable future. The reluctance to design environments and<br />

systems for these types of patients will be short-sighted and<br />

potentially hazardous for the carers delivering the hands on<br />

treatment.<br />

The development of products, equipment and management<br />

systems for the reduction of patient handling risks has seen<br />

improvements (Muir and Archer-Heese 2009, Hignett and<br />

Chipchase, 2007). The range of beds, hoists and handling aids<br />

allows healthcare providers access to a wider variety of physical<br />

solutions to the transfers of larger people.<br />

Summary of literature<br />

The management of patient handling risks has improved over the<br />

past 20 years. The use of education, equipment and management<br />

systems all have made an impact on practice but any reduction in<br />

MSD has not been proven. Recent studies have shown that the<br />

safer methods of mobile hoists and ceiling track systems have<br />

reduced the lifting loads on healthcare workers but there is some<br />

doubt over the push pull requirements to use some hoists.<br />

Evidence that handling bariatric patients is high risk has been<br />

confirmed in one study. Randall et al (2009) showed when<br />

bariatric patients (BMI>35kg/m2) were

2003). The interpretation of this research has focussed on the<br />

removal of lifting tasks and has not evaluated the push pull levels<br />

or the cumulative workload in as much detail. Warming et al<br />

(2009) and Knibbe and Friele (1999), both used self reported logs<br />

to identify the 24 hour exposure to physical loads with a good level<br />

of reliability. These studies show that the number of care related<br />

tasks (e.g. re-positioning, limb movement, push, pull) add<br />

significantly to the patient lifting risks of the lifting/hoisting tasks.<br />

Documented guidance to the safe use of hoists is in most UK<br />

care provider E.g. Fray et al 2001, Smith (Ed) 2005. A task analysis<br />

of the potential phases for hoisting show that many of the physical<br />

tasks may not be improved by the provision of the hoist device.<br />

Table 1 shows the different physical actions that may be included<br />

in a transfer task and whether the provision of different hoist types<br />

affects the completion of the task.<br />

When the use of hoisting systems is compared for the full range<br />

of physical tasks many components are not affected. If this<br />

transfer is compounded by the two surfaces being a significant<br />

distance apart then a transportation phase is also added. The<br />

present design of hoists do not allow for the transportation of<br />

patients over anything other than very short distances. Design<br />

options for the transport of people in a sitting or lying position have<br />

already indicated that for large patients a powered transport<br />

device would be suitable (Kim et al 2009). Some technological<br />

solutions are available to assist in this movement e.g. Bed movers,<br />

powered wheelchairs or trolleys and one motor driven hoist for the<br />

movement of larger patients (www.Smartlift.eu). The need to move<br />

people in a confined space also raises the force requirements and<br />

so powered systems may be indicated in more regular transfer<br />

tasks, e.g. bathing or toileting, with larger patients (Marras et al<br />

2009). The increase in the use of hoisting solutions for other<br />

activities, e.g. during rehabilitation, also suggests the<br />

consideration of powered hoists as a possible requirement.<br />

Financial considerations<br />

Publications that consider handling equipment options have<br />

identified the need for powered systems to assist with patient<br />

transport (Nelson and Fragala, 2004) but noted that the cost might<br />

be prohibitive for integrated powered systems e.g. trolleys.<br />

Charney (2004) and Siddarthan et al (2005) both discuss methods<br />

for calculating the direct, indirect and intangible costs of MSD<br />

resulting from patient handling injuries and guide the calculation of<br />

a cost benefit analysis for provision of any intervention strategy.<br />

The reality of potential losses in UK healthcare is guided by the<br />

NHS pay scales and the replacement fees for lost staff time. As an<br />

example one injury that leads to 3 months<br />

sickness absence of a mid level band 5 nurse<br />

(NHS Employees, 2009) could cost £8400 in the<br />

direct costs of not having the nurse at work, the<br />

same again for the replacement staff to complete<br />

the shift pattern. Without adding all the indirect<br />

expenses and costs this would amount to<br />

£16 800.<br />

The financial balance of prevention against<br />

losses always shows preference to the small fees<br />

for prevention but full investment in prevention<br />

solutions is rarely seen. Solutions for prevention<br />

are regularly delivered at cost minimal solutions so<br />

mobile hoists are preferred. The alternatives of<br />

powered or two dimensional ceiling track hoist systems are price<br />

comparable and might provide a better solution with a cost<br />

effective return through reduced accidents and ill health costs.<br />

Future considerations<br />

The provision of a vertical mechanism passive lifter has some<br />

benefits but it is important to appreciate the cumulative effects of<br />

the other assistive tasks, e.g. pushing, pulling, rolling, positioning,<br />

and transporting patients in the causation of fatigue and possible<br />

injury. The possible costs of increased sickness absence need to<br />

be considered when supplying the mechanical solutions for<br />

handling larger adults in the healthcare environment.<br />

This academic review raises questions that might need to be<br />

considered in the future design of patient handling and healthcare<br />

solutions for the movement and positioning of larger patients:<br />

✚ Improve the understanding of movement and positioning<br />

requirements of the larger individual.<br />

✚ Avoid the pushing and pulling loads by having powered<br />

movement e.g. bed movers and powered hoist movement.<br />

✚ Consider sling sizing and sling design to minimise risks for<br />

application and removal e.g. hoistable clothing.<br />

✚ Consider powered positioning for sitting/reclining, increased<br />

patient comfort and therapeutic benefits e.g. powered<br />

positioning in 3 axes.<br />

✚ Consider the combination of hoists with transport actions to<br />

reduce the in/out manoeuvres for sling application.<br />

✚ Ensure compatibility between the hoisting system and the bed<br />

mechanisms.<br />

✚ Encourage patient handling research to examine the<br />

cumulative load for patient handling tasks in addition to the<br />

single high risk lifting factors.<br />

These considerations are leading the provision of healthcare<br />

tasks towards full automation and the possible use of robots and<br />

intelligent communication to assist with care tasks. Intelligent bed<br />

systems (Hill-Rom 2009) offers patient status information linked<br />

directly to hospital networks. A recent study in the Norwegian<br />

Association of Local and Regional Authorities (Nursing Times<br />

2009) showed that carers would value the use of robots to free up<br />

carers to have more time for face to face duties. A BBC news<br />

(2009) article suggests that technological advances can already<br />

deliver a caring robot to assist with treatments, communication<br />

interventions and patient movement tasks. It is time to consider<br />

how much more we can utilise from innovative solutions rather<br />

than following traditional hoist design? ❏<br />

The <strong>International</strong><br />

<strong>Hospital</strong> <strong>Federation</strong><br />

Our vision is a world of healthy communities served by well<br />

managed hospitals and health services where all individuals<br />

reach their highest potential for health<br />

Origins and aims<br />

The <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong> (IHF), successor to the<br />

<strong>International</strong> <strong>Hospital</strong> Association, established in 1929 after the first<br />

<strong>International</strong> <strong>Hospital</strong> Congress in Atlantic City, USA, was revived<br />

under its new title — <strong>International</strong> <strong>Hospital</strong> <strong>Federation</strong> (IHF) — in<br />

1947. We are an international non-governmental organisation,<br />

supported by members from over 100 countries. As the worldwide<br />

body for hospitals and healthcare organizations we seek to develop<br />

and maintain a spirit of cooperation and communication among<br />

them, with the primary purpose of improving patient safety and<br />

promoting health in underserved communities.<br />

Mission, vision and activities<br />

Our vision is to become a world leader in facilitating the exchange<br />

of knowledge and experience in health sector management, with<br />

our main goals being:<br />

✚ To improve patient care quality around the globe, through the<br />

dissemination of evidence-based information.<br />

✚ To collect, collate, publish and facilitate the exchange of<br />

information and ideas on best practice in hospital and<br />

healthcare management.<br />

✚ To assist in the creation of environments that support<br />

organisations in the promotion and delivery of healthcare.<br />

✚ To foster international partnerships that promote interaction<br />

among public and private hospitals and healthcare<br />

organisations, the community and commercial entities.<br />

✚ To promote and protect the dignity, safety and welfare of<br />

patients.<br />

This vision is promoted through events, publications, networking<br />

and projects in line with our mission and values. These activities<br />

prioritize information on leadership and management of hospitals<br />

and health services.<br />

The IHF is driven by its founding ethos that it is the right of every<br />

human being irrespective of geographical, economic, ethnic or<br />

social condition to enjoy the best standard in quantity and quality<br />

of health and access to hospital and health care services. By<br />

promoting this value, IHF supports the improvement of the health of<br />

society. The provision of health and health care to all people,<br />

recognizes and accepts current best practice in medical standards<br />

and patient care as well as the ethical behaviour and standards of<br />

integrity required to govern, lead and manage health-care<br />

organizations.<br />

Membership and communications<br />

Through our membership and communications activities we seek<br />

to act as a bridge between members in order to facilitate and<br />

support cross-fertilization of knowledge and experience in<br />

management and leadership of health organizations. Through<br />

these activities, we also support the creation of new national<br />

hospital associations. Establishing strong and permanent<br />

communication between the IHF Secretariat and members is a<br />

priority goal.<br />

IHF offers three categories of membership:<br />

✚ <strong>Full</strong> Membership is open to any association or organizational<br />

body deemed representative of the national healthcare<br />

organizations, in particular but not exclusively hospitals, in a<br />

country, a polity or a circumscribed region of the world.<br />

✚ Associate Membership is open to healthcare organizations,<br />

in particular but not exclusively hospitals, and other institutions<br />

having a distinct relationship with the provision of healthcare,<br />

who are not eligible for <strong>Full</strong> Membership.<br />

✚ Honorary Membership is awarded to persons or<br />

organizations who have rendered exceptional services to the<br />

IHF.<br />

IHF reference<br />

The combined membership forms our General Assembly,<br />

which meets every second year during the IHF Biennial World<br />

<strong>Hospital</strong> Congress. Only <strong>Full</strong> Members have the right to vote and<br />

elect members to the Governing Council at the General Assembly.<br />

At present, there are some fifty two <strong>Full</strong> Members, and twenty-one<br />

Governing Council members. The Governing Council in turn elects<br />

from within its ranks an Executive Committee of four, namely the<br />

President, President Designate, Immediate Past President and<br />

Treasurer. The Executive Committee is responsible for conducting<br />

affairs between Council meetings<br />

Partnerships and relations with other organizations<br />

✚ World Confederation for Physical Therapy<br />

Events<br />

These are organized and located to enable us to be present in all<br />

regions of the world. Our regional events are supported by the<br />

Biennial World <strong>Hospital</strong> Congress. The subject focus of each of<br />

these events is tailored to address the needs of the host region,<br />

thereby ensuring our contribution to regional health services<br />

management and development. Our events also provide both a<br />

its aim is to bridge the gap between<br />

scientific evidence and actual practice in<br />

healthcare. It seeks to play a critical role in<br />

establishing global benchmarks in<br />

organizations whose primary focus is<br />

patient care and safety. Its mission also<br />

includes identification and dissemination of<br />

practical knowledge regarding sustainable<br />

applications that would contribute to<br />

GE Healthcare<br />

The burden of surgical diseases is large and is increasing, and there are enormous gaps in access to surgery between high and<br />

low income countries. Surgical services may be cost effective at the district level in LMICs, and providing access to essential<br />

surgery should be viewed as “primary prevention” of death and disability. The integration of essential surgical services into<br />

health systems, within the context of primary healthcare reforms, will surely improve population health.<br />

How Can Health Organizations Get the Most Out of Their Data?<br />

With a Geographic Information System.<br />

In any modern and progressive health organization,<br />

being able to view clinical and administrative<br />

information in its geographic context helps<br />

organizations make better business decisions.<br />

GIS aids in locating scarce health care resources.<br />

Nearly all health data today includes a field that ties it<br />

to a specific place. A geographic information system<br />

(GIS) is the key to bringing this data together and<br />

seeing it in a new way. <strong>Hospital</strong>s, health systems,<br />

managed care plans, physicians, and home health<br />

agencies can all benefit from using a GIS.<br />

ESRI is the world leader in GIS technology. ESRI<br />

offers innovative software solutions that help health<br />

organizations increase the value of the information<br />

they manage. More than 5,000 health clients, 90<br />

ministries of health and 350 hospitals use ESRI<br />

software to help them make better business decisions.<br />
