<strong>The</strong> leading paper in this <strong>issue</strong> is Selak and<br />

colleagues’ Aspirin for primary prevention:<br />

yes or no? 1 <strong>New</strong> <strong>Zealand</strong> (NZ) cardiovascular<br />

disease (CVD) risk guidelines recommend aspirin,<br />

along with lipid and blood pressure–lowering<br />

drugs and lifestyle changes, for all people with a<br />

five-year CVD risk that is 15% or greater. 2 This<br />

recommendation still stands for secondary prevention<br />

(patients who have had a previous CVD<br />

event). However, a recent meta-analysis has cast<br />

doubt on whether the benefits <strong>of</strong> aspirin use outweigh<br />

the potential harms in primary CVD prevention,<br />

concluding that ‘in primary prevention<br />

without previous disease, aspirin is <strong>of</strong> uncertain<br />

net value’. 3 <strong>General</strong> practitioners (GPs) therefore<br />

face a clinical dilemma: should we prescribe aspirin<br />

(unless contraindicated <strong>of</strong> course) for primary<br />

prevention <strong>of</strong> CVD in at-risk patients?<br />

Selak et al.’s research gives us the answer. <strong>The</strong>y<br />

applied evidence-based modelling to the metaanalysis<br />

data (six randomised controlled trials<br />

involving 95 456 individuals without prior CVD<br />

randomised to aspirin or no aspirin) calculating<br />

the rates <strong>of</strong> benefit and <strong>of</strong> harm for men and<br />

women in 10-year age bands, at different levels<br />

<strong>of</strong> CVD risk, both for aspirin alone and also for<br />

aspirin combined with lipid and blood pressure–<br />

lowering drugs.<br />

<strong>The</strong>y found that the benefits <strong>of</strong> aspirin outweigh<br />

the harms for both men and women aged up to 80<br />

years with a five-year CVD risk >15% in primary<br />

prevention. However, harm may outweigh benefit<br />

for primary prevention for those over 80 years,<br />

particularly for men. In men aged 70–79, lipid<br />

and blood pressure–lowering therapies should be<br />

considered first and then the patient reassessed as<br />

to whether aspirin adds an additional net benefit.<br />

This study is a great example <strong>of</strong> translational<br />

research, using the analysis <strong>of</strong> secondary data<br />

to answer a clinical question. We can apply the<br />

evidence to decide whether we should confirm<br />

or change our practice for optimal health care<br />

outcomes. Studies such as this, assessing the marginal<br />

benefits and harms <strong>of</strong> starting and stopping<br />

medication, are the way <strong>of</strong> the future.<br />

<strong>The</strong> topic <strong>of</strong> primary prevention <strong>of</strong> CVD is also<br />

touched on in our ethics column. 4 <strong>The</strong> authors<br />

discuss the difficult balance that doctors need to<br />

find between providing patients with information<br />

on all the possible, but <strong>of</strong>ten rare, adverse<br />

effects <strong>of</strong> management options, and informing<br />

patients about every aspect <strong>of</strong> their condition and<br />

its treatment that they might consider significant.<br />

Statins, like aspirin, are used to prevent<br />

heart attacks and strokes. Statins can cause very<br />

rare but serious and potentially life-threatening<br />

events. Most people are able to accept the remote<br />

risk that something bad may happen, but a few<br />

may be overly concerned to the point that they<br />

‘make bad decisions from a faulty appraisal’<br />

<strong>of</strong> the evidence they are given. Ideally in the<br />

patient-centred approach a GP knows when a<br />

patient might misinterpret or become unrealistically<br />

anxious and tailors how much information<br />

about risks to impart, but the real world is not<br />

always this simple.<br />

<strong>The</strong>se two papers demonstrate the potential<br />

dilemma in practising both population and individual<br />

care. Like the Roman god Janus, we can<br />

be perceived as having two heads facing in opposite<br />

directions. <strong>The</strong> GP who gives statins and<br />

aspirin to his or her at-risk patients knows that a<br />

number are prevented from having a heart attack<br />

or a stroke, and that treating the practice population<br />

in this way leads to an overall improvement<br />

in a number <strong>of</strong> patients’ quality <strong>of</strong> life. However<br />

an individual patient may suffer a severe haemorrhagic<br />

stroke that can be attributed to taking the<br />

aspirin, or rhabdomyolysis and renal failure from<br />

the statin. This is devastating for the person,<br />

their family and their GP. We may act for the<br />

greater good, but sometimes individuals will<br />

suffer harm.<br />

This theme is continued further in a letter to the<br />

editor by Wells and colleagues. 5 <strong>The</strong>y challenge<br />

an essay published in our December 2009 <strong>issue</strong><br />

which argued that using CVD risk pr<strong>of</strong>ile tools<br />

does not improve patient care nor outcomes. 6<br />

Wells et al. agree that merely knowing a patient’s<br />

risk score and giving one-<strong>of</strong>f advice is unlikely<br />

to lead to sustained changes in patient behaviour.<br />

However they provide evidence that integrating<br />

CVD risk pr<strong>of</strong>ile tools into practice management<br />

systems provides immediately available decision<br />

support and generates ‘a comprehensive, personalised<br />

set <strong>of</strong> evidence-based management recommendations’<br />

which can significantly improve<br />

quality <strong>of</strong> care.<br />

Indeed, such clinical decision support systems<br />

help bridge the gap between population and individual<br />

care, taking best evidence obtained from<br />

large populations and tailoring management to fit<br />

a particular patient in the context <strong>of</strong> his or her<br />

specific characteristics, risks and needs.<br />

This <strong>issue</strong> <strong>of</strong> the JPHC also includes a study<br />

exploring the sources that NZ GPs use both for<br />

lifelong learning and to answer clinical questions<br />

arising during consultation. 7 Increasingly GPs<br />

are using web-based tools and resources. This<br />

research was conducted by Zachary Gravatt as a<br />

summer studentship 2008–2009. Tragically, Zac<br />

died last year during his 4th year as a medical<br />

student, and sadly never saw his work in print.<br />

Research pertaining to practice nursing is prominent<br />

this <strong>issue</strong>. <strong>The</strong>re are two papers on chronic<br />

illness care, 8,9 another exploring the preventive<br />

care possibilities from patients seeing the practice<br />

nurse before the GP, 10 a study <strong>of</strong> the enablers and<br />

barriers for practice nurses to advance their pr<strong>of</strong>essional<br />

development, 11 and one addressing the<br />

skills palliative care nurses need to help terminally<br />

ill people remain in control <strong>of</strong> their day-to-day<br />

decisions for as long as possible. 12 <strong>The</strong>re are also<br />

two studies addressing variation in hospitalisation<br />

rates, particularly in Maori 13 and in Pacific<br />

people, 14 and a short report exploring a possible<br />

association <strong>of</strong> unexplained vaginal symptoms and<br />

psychological distress. 15<br />

ABSTRACT<br />

Aim: To assess benefit versus harm <strong>of</strong> aspirin for cardiovascular disease (CVD) primary prevention by<br />

age group, gender and risk category and to interpret these results in light <strong>of</strong> current <strong>New</strong> <strong>Zealand</strong> CVD<br />

risk assessment and management guidelines.<br />

Methods: Rates <strong>of</strong> benefit (avoided vascular events) and harm (additional major extracranial bleeds)<br />

for each gender and age group were calculated from data from the six randomised controlled trials included<br />

in the Anti-Thrombotic Trialists’ (ATT) Collaboration meta-analysis. <strong>The</strong>se rates were applied to CVD<br />

risk categories to calculate the net benefit or net harm likely to occur from the use <strong>of</strong> aspirin in primary<br />

prevention <strong>of</strong> CVD as monotherapy and when added to lipid and blood pressure–lowering therapies.<br />

Results: Benefits <strong>of</strong> aspirin monotherapy outweigh the harms for both men and women aged up to<br />

80 years with calculated five-year CVD risk >15% in primary prevention. Harm may outweigh benefit for<br />

primary prevention for those over 80 years. For men 70–79 years the benefit <strong>of</strong> aspirin in primary prevention<br />

is marginal when added to lipid and blood pressure–lowering therapies.<br />

Discussion: <strong>The</strong> recent ATT Collaboration meta-analysis has raised doubts about the relative safety<br />

<strong>of</strong> aspirin in primary prevention <strong>of</strong> CVD. However, modelling by risk category and age group suggests<br />

that current guidelines are justified in recommending aspirin for primary prevention <strong>of</strong> CVD in those with<br />

five-year CVD risk ≥15% up to the age <strong>of</strong> 80 years. For men 70–79, consider lipid and blood pressure–<br />

lowering therapies first then reassess whether aspirin adds additional net benefit.<br />

Introduction<br />

Cardiovascular disease (CVD) is <strong>New</strong> <strong>Zealand</strong>’s<br />

biggest killer and leading cause <strong>of</strong> loss <strong>of</strong><br />

healthy life years. 1 Current <strong>New</strong> <strong>Zealand</strong> (NZ)<br />

CVD risk assessment and management guidelines<br />

recommend that CVD preventive management<br />

decisions are based on an individual’s<br />

five-year absolute CVD risk. 2 All people with<br />

a five-year CVD risk 15% or greater should be<br />

considered for aspirin, lipid-lowering and blood<br />

pressure–lowering therapies (unless there are<br />

contraindications), in addition to lifestyle interventions,<br />

as necessary to reduce their absolute<br />

risk. This recommendation was made on the<br />

basis that the combination <strong>of</strong> aspirin, lipidlowering<br />

and blood pressure–lowering therapies<br />

is estimated to reduce CVD risk by at least 55%<br />

with a much lower risk <strong>of</strong> harm. 3 While the<br />

role <strong>of</strong> aspirin in the management <strong>of</strong> people<br />

with a prior CVD event remains undisputed,<br />

the recently published Anti-Thrombotic Trialists’<br />

(ATT) Collaboration meta-analysis has<br />

raised doubts about the relative safety <strong>of</strong> aspirin<br />

in the primary prevention <strong>of</strong> CVD. 4 We sought<br />

to model benefit versus harm <strong>of</strong> aspirin for<br />

CVD primary prevention for age group, gender<br />

and risk categories using data from the ATT<br />

Collaboration meta-analysis and to interpret<br />

these results in light <strong>of</strong> current NZ CVD risk<br />

assessment and management guidelines.<br />

ORIGINAL SCIENTIFIC PAPErS<br />

<strong>The</strong> effect <strong>of</strong> adding aspirin to a regime <strong>of</strong> lipid<br />

and blood pressure–lowering therapy among<br />

those with five-year CVD risk >15% was assessed<br />

for each sex / age category. <strong>The</strong> benefit <strong>of</strong> lipidlowering<br />

therapy (statin) and blood pressure–<br />

lowering therapy was estimated from recent<br />

meta-analyses <strong>of</strong> randomised controlled trials. 7,8<br />

Methods<br />

Design<br />

Evidence-based modelling <strong>of</strong> benefit and harm <strong>of</strong><br />

aspirin for primary prevention <strong>of</strong> CVD.<br />

Population<br />

This analysis used results from the ATT Collaboration<br />

meta-analysis, which included 95 456<br />

individuals without prior CVD who had been<br />

randomised to aspirin or no aspirin in six<br />

randomised controlled trials <strong>of</strong> at least 1000 nondiabetic<br />

participants each with at least two years<br />

<strong>of</strong> scheduled treatment. 4<br />

Analysis<br />

Expected CVD events<br />

<strong>The</strong> expected number <strong>of</strong> CVD events based on<br />

five-year CVD risk for a hypothetical population<br />

<strong>of</strong> 1000 people was calculated. For example,<br />

for a hypothetical cohort <strong>of</strong> 1000 people at 1%<br />

five-year CVD risk, 10 CVD events would be expected.<br />

<strong>The</strong> CVD outcomes included in Framingham-based<br />

prediction models (such as those used<br />

in NZ) are myocardial infarction, angina, stroke,<br />

transient ischaemia, congestive heart failure, peripheral<br />

vascular disease and CVD-related death. 5<br />

Benefit<br />

Rates <strong>of</strong> benefit (avoided vascular events) with aspirin<br />

were calculated by applying the proportional<br />

reduction in serious vascular events observed in<br />

the ATT Collaboration meta-analysis (12%, 99%<br />

confidence interval 6–18%) to the number <strong>of</strong> CVD<br />

events expected to be avoided in five years. This<br />

reduction was applied to progressively increasing<br />

five-year CVD risk groups (from 1% to 20%) for<br />

hypothetical populations <strong>of</strong> 1000 people who were<br />

also stratified by gender and 10-year age bands:<br />

50–59, 60–69, 70–79 and 80–89 years. Vascular<br />

events in the meta-analysis were defined as myocardial<br />

infarction, stroke (haemorrhagic or other),<br />

or death from a vascular cause (coronary heart disease<br />

death, stroke death, or other vascular death—<br />

including sudden death, death from pulmonary<br />

embolism, and death from any haemorrhage).<br />

WHAT GAP THIS FILLS<br />

What we already know: <strong>The</strong> benefits <strong>of</strong> aspirin outweigh the risks in<br />

people with a history <strong>of</strong> cardiovascular disease.<br />

What this study adds: <strong>The</strong> benefits <strong>of</strong> aspirin outweigh the risks in primary<br />

prevention <strong>of</strong> CVD in those with five-year CVD risk >15%, up to the age<br />

<strong>of</strong> 80 years, although in men 70–79 consider lipid and blood pressure–lowering<br />

therapies first then reassess whether aspirin adds additional net benefit.<br />

Harm<br />

Rates <strong>of</strong> harm (i.e. the difference between rates<br />

<strong>of</strong> non-fatal major extracranial bleeds in the<br />

aspirin and control groups) were provided by the<br />

ATT Collaboration meta-analysis for men and<br />

women aged 50–59 years (0.2% and 0.1%, respectively).<br />

Non-fatal major extracranial bleeds were<br />

mainly gastrointestinal and usually defined as a<br />

bleed requiring transfusion. Rates <strong>of</strong> harm were<br />

estimated for other age groups (60–69, 70–79<br />

and 80–89 years) by multiplying the rate for<br />

those aged 50–59 years by the rate ratio associated<br />

with age (per decade) identified by the ATT<br />

Collaboration meta-analysis for each additional<br />

decade (2.15, 95% confidence interval 1.93–2.39).<br />

Haemorrhagic stroke and fatal extracranial<br />

haemorrhage were included in vascular events<br />

(see above).<br />

Aspirin monotherapy<br />

Rates <strong>of</strong> benefit and harm were compared in<br />

CVD risk / sex / age categories to assess the net<br />

benefit or net harm likely from the use <strong>of</strong> aspirin<br />

in primary prevention <strong>of</strong> CVD and depicted in<br />

ment in people without a history <strong>of</strong> CVD were<br />

combined using the ratio <strong>of</strong> these events from<br />

the ATT Collaboration meta-analysis to produce a<br />

proportional reduction in the risk <strong>of</strong> CVD events.<br />

Rates <strong>of</strong> harm from the most serious adverse<br />

events associated with statins (rhabdomyolysis)<br />

and antihypertensives (adverse events serious<br />

enough to warrant discontinuation <strong>of</strong> antihypertensive<br />

therapy) were also estimated from metaanalyses<br />

<strong>of</strong> randomised controlled trials. 9,10<br />

Results<br />

Aspirin monotherapy<br />

<strong>The</strong> benefits <strong>of</strong> aspirin are estimated to exceed<br />

the harms at least fourfold among men 60–69<br />

years and women 70–79 who have a calculated<br />

five-year CVD risk >15% in primary prevention<br />

(see Table 1). In people one decade older (men<br />

70–79 and women 80–89) with the same CVD<br />

risk, the number <strong>of</strong> vascular events avoided by<br />

aspirin are still close to twice the harms. From<br />

the age <strong>of</strong> 80 years the harms <strong>of</strong> aspirin are likely<br />

to outweigh the benefits in primary prevention<br />

among men with five-year CVD risk at or just<br />

over 15%.<br />

Adding aspirin to lipid and blood pressure–<br />

For people with a five-year CVD risk <strong>of</strong> 15%,<br />

statin and antihypertensive therapy are estimated<br />

to reduce absolute CVD risk by 6.6% (relative<br />

risk reduction (RRR) <strong>of</strong> 26% and 24% for statin<br />

and antihypertensive therapy respectively applied<br />

in a stepwise fashion to produce an overall RRR<br />

<strong>of</strong> 44%) and increase absolute risk <strong>of</strong> serious side<br />

effects by 0.15% over a five-year period (see Figure<br />

1). <strong>The</strong> balance <strong>of</strong> benefits and risks varies by<br />

sex and age when aspirin is added to the regime.<br />

Aspirin is estimated to reduce absolute CVD risk<br />

by a further 1% (12% RRR), but absolute risk <strong>of</strong><br />

additional serious side effects (extracranial bleeding)<br />

is estimated to increase by 0.20% in men<br />

aged 50–59 years, 0.43% in men 60–69, 0.92% in<br />

men 70–79 and 1.99% in men 80–89. Absolute<br />

risk <strong>of</strong> additional serious side effects is estimated<br />

to increase by 0.10% in women aged 50–59 years,<br />

0.22% in women 60–69, 0.46% in women 70–79<br />

and 0.99% in women 80–89 (see Figure 2).<br />

Discussion<br />

This analysis found that the benefits <strong>of</strong> aspirin<br />

monotherapy outweigh the harms for both men<br />

and women aged up to 80 years with five-year CVD<br />

risk >15% in primary prevention. However, harm<br />

may outweigh benefit for primary prevention for<br />

those over 80 years, particularly for men. <strong>The</strong> proportional<br />

reduction in CVD risk is greater and the<br />

risk <strong>of</strong> serious adverse events is lower with statin<br />

and antihypertensive therapies than with aspirin.<br />

For men 70–79 years the benefit <strong>of</strong> aspirin in primary<br />

prevention is marginal when added to lipid<br />

and blood pressure–lowering therapies. <strong>The</strong>refore,<br />

current <strong>New</strong> <strong>Zealand</strong> CVD risk assessment and<br />

management guidelines are justified in recommending<br />

aspirin for primary prevention <strong>of</strong> CVD in<br />

those with five-year CVD risk ≥15%, up to the age<br />

<strong>of</strong> 80 years, although in men 70–79, lipid and blood<br />

pressure–lowering therapies should be considered<br />

first and additional net benefit <strong>of</strong> aspirin assessed.<br />

This analysis used the most recently published<br />

meta-analysis <strong>of</strong> randomised controlled trials<br />

<strong>of</strong> aspirin for the primary prevention <strong>of</strong> CVD<br />

to model the benefit and harm <strong>of</strong> aspirin. 4 <strong>The</strong><br />

proportional reduction <strong>of</strong> CVD (and increase in<br />

haemorrhagic stroke) with aspirin was assumed<br />

to be constant across sex and age groups. Aspirin<br />

has been shown to reduce CVD primarily<br />

by reducing myocardial infarctions in men and<br />

ischaemic strokes in women. 11 Modelling could<br />

be improved by updating the ATT Collaboration<br />

with more recent trials, 12 obtaining nationally<br />

representative data to provide more up-to-date<br />

and generalisable estimates for rates <strong>of</strong> serious<br />

adverse events and assessing the treatment effect<br />

<strong>of</strong> aspirin by sex and age groups.<br />

<strong>The</strong>re are differences in the way outcomes are<br />

defined that should be considered when interpreting<br />

results. Firstly, haemorrhagic strokes and<br />

fatal extracranial bleeds were included in the<br />

ATT Collaboration’s estimate <strong>of</strong> the proportional<br />

reduction in serious vascular events. This may<br />

explain why their estimate <strong>of</strong> the benefit <strong>of</strong> aspirin<br />

was lower than those previously reported. 2<br />

Secondly, the number <strong>of</strong> estimated CVD events<br />

and those avoided may be slightly overestimated<br />

by the NZ CVD risk assessment and management<br />

guidelines, which use the Framingham<br />

equation, because while the ATT Collaboration<br />

meta-analysis included only serious events<br />

such as myocardial infarction, stroke and death<br />

from CVD (or haemorrhage), the Framingham<br />

equation includes ‘s<strong>of</strong>ter’ CVD events such<br />

as angina, transient ischaemia and peripheral<br />

vascular disease. 5<br />

<strong>New</strong> <strong>Zealand</strong> CVD risk management guidelines<br />

use an adjusted Framingham equation. 2 Certain<br />

groups (on the basis <strong>of</strong> family history, ethnicity,<br />

diabetes status) are moved up one risk category<br />

(5%) during risk assessment and people with<br />

isolated high blood pressure or high cholesterol<br />

are categorised as being at >15% five-year CVD<br />

risk. <strong>The</strong> implications <strong>of</strong> this adjustment to the<br />

absolute benefit likely from medications such<br />

as aspirin in people who have been ‘upgraded’<br />

are not fully known, but there is no obvious<br />

reason to believe that the benefit gained would<br />

be different. However, one study has suggested<br />

that the risk assessment strategy currently used<br />

in <strong>New</strong> <strong>Zealand</strong> for ethnicity adjustment may<br />

be over-estimating risk, 13 while another suggests<br />

that for people who have diabetes with<br />

microalbuminuria, the Framingham equation<br />

underestimates risk substantially, and still underestimates<br />

risk with current adjustments. 14<br />

<strong>The</strong> ATT Collaboration found that the main<br />

risk factors for coronary disease were also risk<br />

factors for bleeding associated with aspirin. 4<br />

Whilst our analysis accounted for the risk<br />

factors with the greatest effect on bleeds (age<br />

and male sex), diabetes, smoking, mean blood<br />

pressure and body mass index have not been<br />

adjusted for.<br />

On the other hand, the ATT Collaboration<br />

meta-analysis is likely to overestimate current<br />

gastrointestinal bleeding rates with aspirin.<br />

<strong>The</strong>re has been an increase in the use <strong>of</strong> triple<br />

eradication therapy (for H. Pylori) and proton<br />

pump inhibitors, along with a reduction in the<br />

use <strong>of</strong> non-steroidal anti-inflammatory agents.<br />

Further, while efforts were made to balance the<br />

severity <strong>of</strong> benefit and harm events, side effects<br />

<strong>of</strong> comparable severity to ischaemic stroke or a<br />

coronary heart disease event are very rare.<br />

Our findings and recommendations are broadly<br />

consistent with, and if anything more conservative<br />

than, British and United States (US) guidelines.<br />

British guidelines advise that the benefit<br />

<strong>of</strong> aspirin in primary prevention outweighs<br />

harm in people aged over 50 years and with<br />

10-year CVD risk >20% (equivalent to five-year<br />

CVD risk >10% 15 ). 16 US guidelines recommend<br />

that aspirin is <strong>of</strong>fered to men 45–79 years and<br />

women 55–79 years when the potential benefit<br />

(reduction in myocardial infarction (MI) in men<br />

and ischaemic stroke in women) outweighs the<br />

potential harm <strong>of</strong> an increase in gastrointestinal<br />

haemorrhage. 6 <strong>The</strong>y estimate that the number<br />

<strong>of</strong> MIs prevented is closely balanced to the<br />

number <strong>of</strong> serious bleeding events when 10-year<br />

coronary heart disease risk is 4% for men 45–69,<br />

9% for men 60–69 and 12% for men 70–79 years<br />

(equivalent to five-year CVD risk 3, 6.75 and<br />

9%, respectively 15 ) . For women, the number <strong>of</strong><br />

ischaemic strokes prevented is estimated to be<br />

closely balanced to the number <strong>of</strong> serious bleeding<br />

events when 10-year stroke risk is 3% for<br />

women 55–59, 8% for women 60–69 and 11% for<br />

women 70–79 years.<br />

<strong>The</strong> proportional reduction with aspirin in the<br />

ATT Collaboration meta-analysis is comparable<br />

across ‘primary’ and ‘secondary’ prevention settings<br />

in cause-specific outcomes: major coronary<br />

events (Rate Ratio 0.82 in primary prevention<br />

vs 0.80 in secondary prevention), ischaemic<br />

stroke (0.86 vs 0.78) and serious vascular event<br />

(0.88 vs 0.81), 4 which questions the rationale for<br />

dichotimising CVD prevention. It is more likely<br />

that CVD risk and benefit from aspirin are on a<br />

continuum.<br />

In conclusion, the findings <strong>of</strong> this analysis<br />

reinforce the importance <strong>of</strong> basing preventive<br />

management decisions on CVD risk. CVD risk<br />

assessment is recommended prior to commencing<br />

aspirin, lipid-lowering and blood pressure–<br />

lowering therapy, and management decisions<br />

should generally be made on the basis <strong>of</strong> this<br />

assessment, according to current guidelines.<br />

From these analyses, aspirin should still be<br />

considered for primary prevention <strong>of</strong> CVD<br />

in those with five-year CVD risk >15%, up to<br />

the age <strong>of</strong> 80 years, although in men 70–79<br />

consider lipid and blood pressure–lowering<br />

therapies first and then reassess whether aspirin<br />

adds additional net benefit.<br />

ABSTRACT<br />

INTRODUCTION: <strong>General</strong> practitioners need to search for evidence to remain up-to-date with knowledge<br />

and to answer clinical questions that arise during consultations. In the past their main sources <strong>of</strong><br />

information have been via colleagues and books.<br />

Aim: To determine the resources Auckland GPs use to answer clinical questions and to maintain lifelong<br />

learning.<br />

Methods: One hundred questionnaires were mailed to Auckland GPs. <strong>The</strong>re were 33 replies (33%<br />

response rate). From this sample 10 were chosen at random and all agreed to be interviewed (100%<br />

response rate).<br />

Results: All participants were using Internet resources to obtain answers to clinical questions. Colleagues<br />

were also important for answering immediate questions, but not for future requirements. <strong>The</strong>re<br />

is possibly less use <strong>of</strong> paper book resources. <strong>The</strong> websites were used to obtain knowledge now and for<br />

future need, while paper books were only used for answering immediate questions.<br />

Discussion: <strong>The</strong> use <strong>of</strong> websites may be increasing in general practice for both immediate knowledge<br />

requirements and for lifelong learning. Colleagues are still a source <strong>of</strong> answers to immediate clinical questions,<br />

but textbooks may be less used. Empiric data are needed to monitor changes in answering clinical<br />

questions and the <strong>issue</strong> <strong>of</strong> lifelong learning requires more research.<br />

Introduction<br />

For medicine to continue to be respected as a<br />

pr<strong>of</strong>ession, evidence-based decision-making is<br />

required where this is possible. This in turn<br />

depends on physicians being able to understand<br />

how and why they make decisions. 1 In particular,<br />

evidence-based decision-making requires a ‘conscientious,<br />

explicit and judicious use <strong>of</strong> current<br />

best evidence in making decisions about the care<br />

<strong>of</strong> individual patients’. 2 It is this definition that<br />

underpins evidence-based medicine (EBM). By applying<br />

such a definition it becomes apparent that<br />

physicians’ knowledge following formal graduation<br />

will not remain current throughout their<br />

careers unless they develop skills enabling them<br />

to participate in lifelong learning (LLL). 3<br />

<strong>General</strong> practitioners (GPs) are likely to search<br />

for evidence for two primary reasons. <strong>The</strong> first<br />

is to keep up-to-date with new information 4<br />

and modern clinical opinion. This style <strong>of</strong> LLL<br />

and continuing medical education (CME) relies<br />

considerably on individuals’ own awareness <strong>of</strong><br />

strengths and weaknesses in their knowledge. 5<br />

It has been suggested that GPs have imperfect<br />

abilities to judge their own learning requirements<br />

and external assessment is one proposed<br />

solution to this. 6,7 Currently GPs believe CME<br />

quantitative research<br />

is advantageous and can lead to patient benefits. 8<br />

<strong>The</strong> literature suggests GPs may be somewhat<br />

misguided in this belief, because CME sessions<br />

only occasionally change health outcomes or<br />

result in pr<strong>of</strong>essional development. 9,10 This might<br />

result from a preponderance <strong>of</strong> poor quality CME<br />

activities with low levels <strong>of</strong> effectiveness. 11<br />

<strong>The</strong> second reason GPs might search for evidence<br />

is to answer questions generated by patients. 4<br />

However this can be an arduous and problematic<br />

task due to the time and effort required to navigate<br />

the large and ever-expanding wealth <strong>of</strong> medical<br />

information available. 4 Consequently, GPs may be<br />

unable to answer reliably 70% <strong>of</strong> clinical questions<br />

for which they have sought answers. 4 For certain<br />

questions electronic textbooks such as DynaMed,<br />

MDConsult and UpToDate might prove to be<br />

a reasonable resource for this problem. 12 <strong>The</strong>se<br />

electronic textbooks are comprehensive, reasonably<br />

evidence-based where such information is<br />

available, and can give answers to common clinical<br />

questions in a few minutes <strong>of</strong> searching.<br />

Previous research exploring the ways <strong>New</strong><br />

<strong>Zealand</strong> GPs answer patient questions has been<br />

reported. This demonstrated that, although the<br />

majority <strong>of</strong> GPs had access to computers, they<br />

were not the most frequently used source for<br />

answering patient questions. 13 Instead, answers<br />

are most likely to be sought from books, followed<br />

by colleagues. 13 <strong>The</strong>se patient questions were<br />

most likely to focus on <strong>issue</strong>s related to treatment<br />

or diagnosis. 13<br />

On the <strong>issue</strong> <strong>of</strong> information sources used to<br />

find answers to clinical questions, interesting<br />

differences arise between GPs and specialists. 4,14<br />

A 2005 <strong>New</strong> <strong>Zealand</strong> survey found that <strong>New</strong><br />

<strong>Zealand</strong> GPs want information that is presented<br />

concisely, clearly, timely, attractively and is<br />

‘owned’ and trusted by them. 16 GPs are unlikely<br />

to seek original research articles, but instead<br />

opt to conduct Internet searches. Specialists,<br />

however, are more likely to search the literature<br />

and journals or enter into correspondence with<br />

colleagues. 16 Family medicine residents who are<br />

trained in EBM are unlikely to perform evidencebased<br />

searches at the point <strong>of</strong> care, but instead<br />

use sources that allow them access to answers<br />

swiftly and conveniently. 4,16<br />

WHAT GAP THIS FILLS<br />

What we already know: GPs used colleagues and books in the past to<br />

answer immediate clinical questions. <strong>The</strong>re is no recent overview <strong>of</strong> how<br />

general practitioners acquire clinical information and keep up-to-date.<br />

What this study adds: Colleagues are still a common source <strong>of</strong> information,<br />

but it appears that paper books are being replaced with electronic resources.<br />

Websites are used both to answer clinical questions and to facilitate<br />

lifelong learning.<br />

<strong>The</strong> aim <strong>of</strong> this study was to determine the resources<br />

used by GPs for lifelong learning and to<br />

retrieve answers to clinical questions as they arise<br />

during a consultation.<br />

Methods<br />

One hundred questionnaires were mailed to a<br />

random selection <strong>of</strong> Auckland GPs using the<br />

Department <strong>of</strong> <strong>General</strong> Practice and Primary<br />

Health Care (Auckland University) database <strong>of</strong><br />

Auckland GPs. This database is regularly updated.<br />

<strong>The</strong> questionnaire asked about sources <strong>of</strong><br />

information (such as websites, books, colleagues,<br />

email), how <strong>of</strong>ten they were used and how <strong>of</strong>ten<br />

an ‘answer’ was found. <strong>The</strong>re were 33 replies<br />

(33% response rate). It was considered that the<br />

responders were likely to be interested GPs keen<br />

on lifelong learning.<br />

From this sample 10 were chosen at random<br />

and all agreed to be interviewed (100% response<br />

rate). <strong>The</strong> interview was conducted by<br />

telephone and notes were taken rather than an<br />

audio-recording. <strong>The</strong> interviewer had the GP’s<br />

answers to the original questionnaire to guide<br />

the GP through the interview. <strong>The</strong>se interviews<br />

were conducted between December 2008 and<br />

February 2009.<br />

<strong>The</strong> GPs were asked which sources <strong>of</strong> information<br />

they used for particular enquiries; specifically,<br />

websites, online text, journals (electronic or<br />

paper), paper books, colleagues, audits, prescribing<br />

sources and email feeds. For each answer<br />

the GP was asked for the name <strong>of</strong> the source, if<br />

payment was required, if it was a source accessed<br />

when needed (a ‘pull’ resource) or information<br />

that is sent to them routinely (a ‘push’ resource),<br />

questions from Internet resources and colleagues<br />

than from books.<br />

Discussion<br />

This study shows that all the participants were<br />

using the Internet both to seek information for<br />

questions requiring an answer now and for future<br />

learning. Half were using it daily. Colleagues and<br />

paper-based sources were only used daily by one<br />

<strong>of</strong> the participants and only used for immediate<br />

clinical questions.<br />

This may represent a change in information seeking<br />

when compared with another Auckland-based<br />

study in 2002 where computers were rarely used<br />

to answer clinical questions. Colleagues including<br />

GPs, specialists and pharmacists were still common<br />

sources <strong>of</strong> information. 13 <strong>The</strong> use <strong>of</strong> journal<br />

articles or searching for literature other than<br />

through search engines was rare. We were also<br />

surprised at the wide range <strong>of</strong> websites used and<br />

the fact that some were using web resources daily<br />

and some less <strong>of</strong>ten.<br />

A strength <strong>of</strong> this study is that each <strong>of</strong> the 10<br />

GPs was able to be interviewed in some depth<br />

about their information approaches. A limitation<br />

is that they are a self-selected group <strong>of</strong> highly<br />

motivated learners who probably represent one<br />

end <strong>of</strong> a spectrum <strong>of</strong> GPs and are not representative<br />

<strong>of</strong> all GPs. However, the study intended to<br />

interview such a group to see what innovations<br />

are possible in the primary care setting. It was<br />

not possible to do an in-depth interview on a<br />

wide range <strong>of</strong> GPs with the resources available to<br />

the study.<br />

In the words <strong>of</strong> McConaghy we agree that<br />

‘clinicians must learn the techniques and skills<br />

to focus on finding, evaluating and using<br />

ACKNOWLEDGEMENTS<br />

Thank you to the GPs who<br />

relevant and valid information at the point<br />

<strong>of</strong> care. Clinicians also need sources for rapid<br />

retrieval <strong>of</strong> this information to integrate it into<br />

their daily practice and their careers <strong>of</strong> lifelong<br />

learning.’ 4 <strong>The</strong> GPs in our sample certainly<br />

have ‘sources for rapid retrieval’ and are using<br />

‘relevant’ information; they are probably also<br />

getting ‘valid’ information, given the resources<br />

they have nominated.<br />

Web resources have the potential to provide<br />

both immediate answers to clinical questions<br />

and contribute to lifelong learning. <strong>The</strong> possible<br />

change from textbooks to web resources has the<br />

additional advantages <strong>of</strong> providing clinicians<br />

with up-to-date information which is not possible<br />

with paper textbooks. Future research is needed<br />

and perhaps it would be worthwhile repeating<br />

the study <strong>of</strong> 2002 to see how answering clinical<br />

questions may have changed. 13 <strong>The</strong> <strong>issue</strong> <strong>of</strong> lifelong<br />

learning (knowledge for the future) needs<br />

more research.<br />

ABSTRACT<br />

introduction: Pacific people suffer disproportionately poorer health and reduced life expectancy at<br />

birth compared to the total <strong>New</strong> <strong>Zealand</strong> population.<br />

Department <strong>of</strong> Preventive<br />

and Social Medicine,<br />

University <strong>of</strong> Otago,<br />

<strong>New</strong> <strong>Zealand</strong><br />

Aim: To assess causes <strong>of</strong> excess morbidity in the Pacific population, and identify lesser known or previously<br />

unknown causes which require further investigation.<br />

Methods: We obtained public hospital discharge data from July 2000 to December 2002. <strong>The</strong> population<br />

data were from the 2001 Census. Standardised discharge ratios were calculated to compare Pacific<br />

peoples with the total <strong>New</strong> <strong>Zealand</strong> population.<br />

Results: Pacific peoples were six times more likely to have a diagnosis <strong>of</strong> cardiomyopathy and gout,<br />

and four to five times <strong>of</strong> rheumatic fever, gastric ulcer, systemic lupus erythematosus (SLE), and diabetes.<br />

Respiratory diseases, skin abscesses, heart failure, cataracts, cerebral infarction and chronic renal failure<br />

were also significant causes <strong>of</strong> excess morbidity. Unexpected causes <strong>of</strong> excess morbidity included candidiasis,<br />

excess vomiting in pregnancy (hyperemesis gravidarum) and pterygium.<br />

discussion: <strong>The</strong> magnitude <strong>of</strong> established causes <strong>of</strong> excess morbidity among Pacific peoples were<br />

similar to our findings. Other causes <strong>of</strong> excess morbidity are less widely known, or are identified here for<br />

the first time. <strong>The</strong>se are systemic lupus erythematosus, hyperemesis gravidarum, cardiomyopathy, gastric<br />

ulcer, candidiasis and pterygium. <strong>The</strong> findings draw attention to specific causes <strong>of</strong> excess morbidity in Pacific<br />

communities where effective interventions are available in primary care, and where further research<br />

may identify preventive or curative interventions.<br />

KEYWORDS: Pacific peoples; primary care; hyperemesis gravidarum; morbidity; hospitalizations<br />

Introduction<br />

<strong>The</strong> Pacific population makes up approximately<br />

7% <strong>of</strong> the total <strong>New</strong> <strong>Zealand</strong> population from<br />

the 2006 Census. 1 Pacific people suffer disproportionately<br />

from poorer health and, in 2001,<br />

their life expectancy at birth was five years less<br />

compared to the total <strong>New</strong> <strong>Zealand</strong> population. 2,3<br />

<strong>The</strong> focus <strong>of</strong> many health intervention programmes<br />

is on addressing this disparity in health<br />

status. To decrease disparities it is important to<br />

understand the range <strong>of</strong> health problems which<br />

disproportionately affect Pacific peoples. Some <strong>of</strong><br />

these problems have already been identified from<br />

mortality and health survey data. 2–5 Nevertheless,<br />

there is limited information published on the<br />

occurrence <strong>of</strong> chronic conditions among Pacific<br />

peoples in <strong>New</strong> <strong>Zealand</strong>.<br />

This study was carried out as part <strong>of</strong> a health<br />

needs analysis for Pacific peoples commissioned by<br />

the Ministry <strong>of</strong> Health. Our aim was to determine<br />

the specific causes <strong>of</strong> hospital admissions which<br />

are significantly elevated in the Pacific population.<br />

This will provide information that may assist early<br />

diagnosis and treatment in primary care, and may<br />

result in better outcomes for Pacific peoples.<br />

quantitative research<br />

Methods<br />

We undertook a systematic examination <strong>of</strong> public<br />

hospital discharge diagnoses (as a measure <strong>of</strong><br />

morbidity) to determine which conditions are<br />

relatively important causes <strong>of</strong> morbidity among<br />

Pacific peoples compared to the total population<br />

in <strong>New</strong> <strong>Zealand</strong>. <strong>The</strong> results presented are<br />

for those who were admitted to hospital only.<br />

Patients who were seen at the emergency department<br />

and discharged were excluded.<br />

<strong>The</strong> hospital activity data used in this study were<br />

obtained from the <strong>New</strong> <strong>Zealand</strong> Health Information<br />

Service <strong>of</strong> the Ministry <strong>of</strong> Health, and relate<br />

to public hospital discharges for the period July<br />

2000 to December 2002. <strong>The</strong> population data<br />

were derived from Statistics <strong>New</strong> <strong>Zealand</strong> census<br />

data for 2001. Discharge diagnoses were coded to<br />

International Classification <strong>of</strong> Diseases (ICD) 10.<br />

‘Pacific peoples’ included anyone who reported<br />

sole Pacific Island ethnicity or Pacific Island ethnicity<br />

as well as another ethnic group or groups<br />

from hospital discharges.<br />

Standardised discharge ratios (SDRs) were<br />

calculated using the rate <strong>of</strong> discharges per capita<br />

by age group for the total population, applied to<br />

the age structure <strong>of</strong> the Pacific population. This<br />

provides an estimate <strong>of</strong> the expected number <strong>of</strong><br />

discharges that the Pacific population would have<br />

had, given its own population structure, but with<br />

discharge rates equal to those in the population<br />

at large. Effectively we adjust for the younger age<br />

structure <strong>of</strong> the Pacific population. <strong>The</strong> expected<br />

number <strong>of</strong> discharges for Pacific people formed<br />

the denominator, and the observed number <strong>of</strong><br />

discharges the numerator. SDRs higher than one<br />

thus imply higher standardised discharges among<br />

Pacific peoples compared to the total population.<br />

Further adjustment were made to the expected<br />

number <strong>of</strong> discharges to allow for the different<br />

fertility pattern <strong>of</strong> Pacific peoples. For those conditions<br />

that relate to pregnancies and births, we<br />

multiplied the expected number <strong>of</strong> hospitalisations<br />

by the relative birth rate for Pacific peoples<br />

compared to the population as a whole.<br />

Given the relatively small number <strong>of</strong> hospitalisation<br />

events, the frequency <strong>of</strong> occurrence in the<br />

two population groups can differ by chance. Confidence<br />

is usually represented statistically by confidence<br />

intervals (CIs); these intervals show the<br />

range <strong>of</strong> values in which we can be 95% confident<br />

that the ‘true’ value lies. <strong>The</strong> CIs for the SDRs<br />

were calculated using an algorithm described by<br />

Byar. 6 This algorithm makes allowances for the<br />

lower confidence we can place on estimates from<br />

smaller samples. Because the SDRs are distributed<br />

non-normally, we applied a log transformation<br />

before calculating the standardised distance from<br />

the mean in terms <strong>of</strong> the number <strong>of</strong> CIs. <strong>The</strong><br />

method is effectively a measure <strong>of</strong> our certainty<br />

that the disease differs from the population<br />

standard, and might be thought <strong>of</strong> as equivalent<br />

to a ‘z’ score. <strong>The</strong> ICD-10 diagnoses where the<br />

standardised distance from the mean was in the<br />

top 5% <strong>of</strong> values are presented.<br />

Permission for access to data was granted from<br />

the Ministry <strong>of</strong> Health.<br />

Results<br />

During the study period July 2000 to December<br />

2002, there were 2 831 789 discharges from<br />

all public hospitals in <strong>New</strong> <strong>Zealand</strong>. Of these,<br />

99 476 (3.5%) were identified as Pacific peoples.<br />

<strong>The</strong> number <strong>of</strong> people responding to the ethnicity<br />

question in the 2001 Census was 3 586 731<br />

(96%), and 231 801 (6.2 %) identified themselves<br />

as Pacific peoples. <strong>The</strong> apparent lower proportion<br />

admitted to hospital is because <strong>of</strong> differences in<br />

the age structure <strong>of</strong> the Pacific population compared<br />

to the total population.<br />

Table 1 shows the 24 discharge diagnoses which<br />

were most elevated for Pacific peoples; that is, the<br />

top 5% <strong>of</strong> values. Pacific peoples were around two<br />

to six times more likely to be discharged from<br />

hospital with these conditions. More specifically,<br />

Pacific peoples were six times more likely to have<br />

a diagnosis <strong>of</strong> cardiomyopathy and gout, and four<br />

to five times more likely to have rheumatic fever,<br />

gastric ulcer, systemic lupus erythematosus (SLE),<br />

diabetes and its associated complications. Respiratory<br />

diseases were also a significant cause <strong>of</strong><br />

excess morbidity with discharges for bronchiectasis<br />

nearly five times, and pneumonia at least two<br />

times more in comparison. Skin abscesses, heart<br />

failure, cataracts, cerebral infarction and chronic<br />

renal failure were at least twice as likely to be<br />

discharge diagnoses. <strong>The</strong>re were some unexpected<br />

findings also, where Pacific peoples were five<br />

times more likely to have candidiasis, and ‘other<br />

disorders <strong>of</strong> the conjunctiva’ and two times more<br />

likely to have hyperemesis gravidarum compared<br />

to the total <strong>New</strong> <strong>Zealand</strong> population, after adjustment<br />

for fertility rates. When looking at the<br />

four-character ICD code for candidiasis, 90% <strong>of</strong><br />

Pacific cases were due to either cheilitis (candidiasis<br />

<strong>of</strong> the mouth) or enteritis. <strong>The</strong> four-character<br />

ICD code for other disorders <strong>of</strong> the conjunctiva<br />

showed 97% <strong>of</strong> cases were pterygium. Of the six<br />

WHAT GAP THIS FILLS<br />

What we already know: <strong>The</strong> main known causes <strong>of</strong> excess morbidity<br />

amongst Pacific peoples in <strong>New</strong> <strong>Zealand</strong> are respiratory and cardiovascular<br />

diseases, diabetes, gout, skin infections, rheumatic fever, and their associated<br />

complications.<br />

What this study adds: Causes <strong>of</strong> excess morbidity among Pacific people<br />

that are less well known, or reported here for the first time, are: cardiomyopathy,<br />

systemic lupus erythematosus, hyperemesis gravidarum, gastric ulcer,<br />

candidiasis, and pterygium. Early diagnosis and treatment <strong>of</strong> these conditions<br />

in primary care will reduce morbidity.<br />

most common diagnoses, pneumonia, acute bronchiolitis<br />

and asthma each resulted in over 2000<br />

admissions during this period. Skin infections,<br />

cellulitis, and hyperemesis gravidarum each were<br />

a cause <strong>of</strong> over 1000 admissions.<br />

Discussion<br />

Our results provide a description <strong>of</strong> the illnesses<br />

causing hospital admissions which most clearly<br />

affect Pacific peoples disproportionately compared<br />

to the total <strong>New</strong> <strong>Zealand</strong> population. Some <strong>of</strong><br />

these causes <strong>of</strong> morbidity were consistent with<br />

what is already known; however, there were also<br />

some unexpected findings. <strong>The</strong> cut-<strong>of</strong>f <strong>of</strong> the top<br />

5% was arbitrary, but chosen in order to include<br />

only differences which we were confident were<br />

not chance findings. Moreover, by taking the<br />

top 5% <strong>of</strong> conditions we satisfy the Bonferroni<br />

correction for multiple sampling (to allow for the<br />

possibility that some significant results would<br />

Public hospital discharge data, despite the<br />

limitations discussed, are a good measure<br />

<strong>of</strong> morbidity amongst Pacific peoples<br />

occur purely by chance when considering a large<br />

number <strong>of</strong> statistics). A number <strong>of</strong> conditions<br />

which are known to be higher amongst Pacific<br />

peoples were below this cut-<strong>of</strong>f. 2 For example,<br />

meningococcal infection (SDR 2.11), gastric<br />

cancer (SDR 2.98), and tuberculosis (SDR 3.57).<br />

Many <strong>of</strong> the illnesses resulting in admissions<br />

for Pacific peoples in this study can either be<br />

prevented, their severity reduced, or complications<br />

delayed, through effective primary care<br />

interventions.<br />

<strong>The</strong>re were some limitations in our study. It was<br />

a snapshot <strong>of</strong> morbidity and does not <strong>of</strong>fer any<br />

information about trends over time. ICD discharge<br />

diagnosis coding will contain errors, but<br />

these could not account for large differences. <strong>The</strong><br />

results show admissions not people. If Pacific people<br />

have a higher number <strong>of</strong> re-admissions than<br />

the total population, this could account for some<br />

<strong>of</strong> the excess. Because <strong>of</strong> potential differences in<br />

knowledge, access to services, and referrals for<br />

treatment, it may be that SDRs for Pacific peoples<br />

are higher (or lower) on average, for reasons that<br />

are unrelated to levels <strong>of</strong> morbidity. <strong>The</strong> most<br />

extreme SDRs, however, are likely to indicate<br />

conditions within the Pacific community that<br />

are associated with the highest levels <strong>of</strong> excess<br />

morbidity. Ethnicity data collection has improved<br />

since 1995 and there are changes in how ethnicity<br />

data are now collected. However, there are<br />

persisting <strong>issue</strong>s with the recording <strong>of</strong> ethnicity<br />

in <strong>New</strong> <strong>Zealand</strong> with underenumeration <strong>of</strong> Maori<br />

and Pacific peoples. 7–8 This means the elevated<br />

rates observed may be an underestimation. On the<br />

other hand, the definition <strong>of</strong> Pacific ethnicity in<br />

the hospitalisation data and the census differ (the<br />

former prioritised Pacific, the latter prioritised<br />

Maori). This could lead to an overestimation <strong>of</strong><br />

the elevated rates in Pacific people, but any effect<br />

will be very small. Private hospital data were not<br />

included. If Pacific peoples use private hospitals<br />

less, this may result in an overestimation <strong>of</strong> the<br />

elevated rates. This is likely to be a minor problem<br />

for the conditions examined, as most <strong>of</strong> these<br />

are treated in public hospitals for everyone.<br />

<strong>The</strong> strengths <strong>of</strong> this study include the large<br />

number <strong>of</strong> admissions, hence the statistical<br />

power. Public hospital discharge data, despite<br />

the limitations discussed, are a good measure <strong>of</strong><br />

morbidity amongst Pacific peoples.<br />

Our results, compared to other published data,<br />

showed similar or higher excess rates for respiratory<br />

diseases, heart failure, rheumatic fever,<br />

cerebral infarction (stroke), and diabetes and<br />

other related conditions. For instance, the annual<br />

hospitalisation rate for pneumonia in Pacific children<br />

in Auckland was twice as high, while the<br />

national incidence <strong>of</strong> bronchiectasis was at least<br />

10 times higher compared to Europeans. 9,10 <strong>The</strong><br />

prevalence <strong>of</strong> diabetes in the Pacific population,<br />

at 23.5%, was higher compared to all other ethnic<br />

groups. 11 Pacific mortality from heart failure and<br />

stroke was at least double compared to the total<br />

population. 2 Cardiomyopathy was six times more<br />

common among Pacific peoples in our study,<br />

but there appears to be no previous research on<br />

this. We found that a whole range <strong>of</strong> respiratory<br />

illnesses were significantly more common among<br />

Pacific people. In terms <strong>of</strong> burden <strong>of</strong> disease (total<br />

numbers), respiratory diseases were the most<br />

important. Many <strong>of</strong> these illnesses are influenced<br />

by socioeconomic and environmental conditions.<br />

We found Pacific peoples were at least six times<br />

more likely to have a diagnosis <strong>of</strong> gout, and four<br />

times more likely to have gastric ulcer. Research<br />

into the aetiology <strong>of</strong> gout in Pacific people had<br />

identified a potential genetic link, which may<br />

act in conjunction with diet and obesity. 12,13<br />

Indigenous Fijians had a higher prevalence <strong>of</strong><br />

gastric ulcers diagnosed by endoscopic examination<br />

than Fijian Indians. 14 Risk factors for gastric<br />

ulcers included helicobacter pylori (H.pylori)<br />

infection, non-steroidal anti-inflammatory drugs<br />

and smoking. 15–16 H.pylori IgG seropositivity<br />

has been shown to be highest in Pacific peoples<br />

compared to either Maori or people <strong>of</strong> European<br />

ethnicity. 17 Antibiotic treatment is effective for<br />

H.pylori eradication.<br />

We found Pacific peoples were at least 1.5 times<br />

more likely to have a diagnosis <strong>of</strong> cellulitis, and<br />

five times more likely to have rheumatic fever<br />

compared to the total <strong>New</strong> <strong>Zealand</strong> population.<br />

Cellulitis is caused by either Group A streptococcus<br />

or staphylococcus aureus. 18 A complication <strong>of</strong><br />

Group A streptococcus infection is acute rheumatic<br />

fever. Skin infections are more common<br />

among Pacific children. 3 High rates <strong>of</strong> rheumatic<br />

fever are linked to socioeconomic conditions, and<br />

consistent with previous findings for Maori and<br />

Pacific peoples. 2,19 Improved socioeconomic conditions<br />

and access to early diagnosis and treatment<br />

can reduce the development <strong>of</strong> complications.<br />

Most pregnant women experience some degree<br />

<strong>of</strong> nausea and vomiting. Previous research based<br />

on a review <strong>of</strong> medical notes found the incidence<br />

<strong>of</strong> hyperemesis gravidarum in Pacific Island<br />

women was higher compared to either Maori or<br />

Europeans. 20,21 We found Pacific women to be<br />

two times more likely to be hospitalised because<br />

<strong>of</strong> hyperemesis gravidarum compared to the total<br />

<strong>New</strong> <strong>Zealand</strong> population, and this accounted for<br />

a high burden <strong>of</strong> disease (over 1000 admissions<br />

in 2.5 years). Recent research showed a consistent<br />

association between hyperemesis gravidarum and<br />

H.pylori, with relief <strong>of</strong> symptoms after antibiotic<br />

treatment for H.pylori. 22,23 Given the higher<br />

prevalence <strong>of</strong> H.pylori this is a plausible cause <strong>of</strong><br />

hyperemesis gravidarum among Pacific women,<br />

although psychosocial factors and disorders <strong>of</strong><br />

thyroid function are also possible causes. 23 We<br />

could find no evidence that any clinical trial <strong>of</strong><br />

treatment <strong>of</strong> H.pylori in women with hyperemesis<br />

gravidarum has been undertaken.<br />

Candida is a commensal found in the mouth,<br />

stool and vagina. 18 Invasive candidiasis is a serious<br />

problem in diabetic patients. 24 Our results<br />

showed Pacific peoples were nearly five times<br />

more likely to be discharged with a diagnosis <strong>of</strong><br />

candida enteritis and cheilitis, compared to the<br />

total <strong>New</strong> <strong>Zealand</strong> population. <strong>The</strong>re has been no<br />

previous research on ethnic differences in susceptibility<br />

to candidiasis in <strong>New</strong> <strong>Zealand</strong>. Research<br />

is required to find out why Pacific peoples appear<br />

to be more susceptible.<br />

<strong>The</strong> prevalence <strong>of</strong> SLE is known to vary among<br />

people <strong>of</strong> different ethnic groups. 25–29 A review<br />

<strong>of</strong> medical notes in <strong>New</strong> <strong>Zealand</strong> in the 1980s<br />

showed a major difference in prevalence when<br />

comparing people <strong>of</strong> European ethnicity and Polynesians.<br />

30 <strong>The</strong> Polynesian ethnic group included<br />

Maori and Pacific peoples. Polynesians were 3.5<br />

times more likely to have SLE compared to the<br />

European population in <strong>New</strong> <strong>Zealand</strong>. Age standardised<br />

comparative mortality rates were also<br />

higher. Our findings are similar, with Pacific peoples<br />

four times more likely to have SLE compared<br />

to the total <strong>New</strong> <strong>Zealand</strong> population. It would<br />

be helpful to look at Maori and Pacific peoples<br />

separately, to provide clarity about morbidity and<br />

mortality from SLE in these ethnic groups.<br />

Pterygium is a ‘wedge-shaped fibrovascular<br />

growth <strong>of</strong> conjunctiva that extends onto the<br />

cornea’. 18 <strong>The</strong> prevalence is higher in countries<br />

nearer the equator, and appears to be associated<br />

with sun exposure. 31–32 We did not have information<br />

about the country <strong>of</strong> birth for Pacific peoples<br />

in this study. It is possible that the higher prevalence<br />

<strong>of</strong> cases seen is due to Pacific peoples from<br />

the Pacific Islands now living in <strong>New</strong> <strong>Zealand</strong>.<br />

This association does not appear to have been<br />

documented previously.<br />

COMPETING INTERESTS<br />

None declared.<br />

vascular diseases, diabetes, gout, skin infections<br />

and their associated complications—were all<br />

considerably more common discharge diagnoses<br />

compared with the total population in this<br />

analysis. <strong>The</strong>se disorders are already the focus <strong>of</strong><br />

attention, and it is important for primary health<br />

care pr<strong>of</strong>essionals to continue working collaboratively<br />

with Pacific communities to improve<br />

health in these areas.<br />

Other causes <strong>of</strong> excess morbidity in Pacific peoples<br />

are less widely known, or are identified here<br />

for the first time. <strong>The</strong>se are cardiomyopathy, SLE,<br />

hyperemesis gravidarum, gastric ulcer, candidiasis<br />

and pterygium. <strong>The</strong> clinical implications<br />

are that improved knowledge amongst general<br />

practitioners <strong>of</strong> the excess risk <strong>of</strong> these conditions<br />

in Pacific peoples will lead to earlier diagnosis,<br />

treatment and improved outcomes. Further research<br />

is required to establish the cause <strong>of</strong> excess<br />

hyperemesis gravidarum in the Pacific population<br />

and the potential for treatment.<br />

Although a main focus on the broader socioeconomic<br />

determinants <strong>of</strong> health is appropriate in<br />

order to improve the health <strong>of</strong> Pacific peoples, it<br />

is important also to attend to specific causes <strong>of</strong><br />

morbidity where effective interventions are available,<br />

and where further research may identify<br />

preventive or curative interventions.<br />

Methods: Practice enrolment data for 345 254 patients enrolled with 102 Partnership Health Primary<br />

Health Organisation (PHO) general practices were sent to <strong>New</strong> <strong>Zealand</strong> Health Information Service. Data<br />

linked to the patient National Health Index (NHI) relating to hospital discharges were attached to the<br />

practice enrolment data for the two years ending June 2007 and returned to the researchers with the NHI<br />

numbers encrypted. Total discharges were 127 426.<strong>The</strong> data were analysed for rates <strong>of</strong> hospital discharges<br />

for different population groups and by general practice.<br />

Results: <strong>The</strong>re is a substantial variation in hospital discharge rates between general practices, but this<br />

is only partly accounted for by practice population characteristics. Furthermore while there is a strong<br />

social gradient in European admissions, this is much less true for Maori. <strong>The</strong>re was also a wide variation<br />

between practices in the uptake <strong>of</strong> High Use Health Cards, special funding for frequent attenders at general<br />

practices and ‘Care Plus’ funding for patients with chronic conditions. Practice deprivation, ethnicity<br />

and age only explained a minor part <strong>of</strong> this variation.<br />

Discussion: <strong>The</strong> high rate <strong>of</strong> unexplained practice variation in chronic care management and hospitalisation<br />

rates, especially for Maori, is <strong>of</strong> concern. Further investigation <strong>of</strong> the causes <strong>of</strong> such variability is<br />

needed as a first step in reducing hospitalisation.<br />

Introduction<br />

Reduction <strong>of</strong> hospital admissions through greater<br />

intensity <strong>of</strong> care in primary health care has been<br />

strongly emphasised in many countries, including<br />

<strong>New</strong> <strong>Zealand</strong>. <strong>The</strong> evidence from the experience<br />

<strong>of</strong> Kaiser Permanente, a large United States<br />

Health Maintenance Organisation, is that hospital<br />

admissions can be halved through appropriate<br />

use <strong>of</strong> the primary care sector. 1 A key factor in<br />

this strategy is the organisational integration <strong>of</strong><br />

primary and secondary care such as is now being<br />

addressed by District Health Boards (DHBs).<br />

Canterbury DHB, in conjunction with the<br />

primary care sector in Christchurch including<br />

Pegasus Health, have sought to reduce demand<br />

upon emergency department and hospital services<br />

through primary care alternatives. Attention has<br />

now shifted to what has being hailed as the<br />

‘Canterbury Initiative’. 2 <strong>General</strong> practitioners<br />

and specialists are working together to develop<br />

and implement mutually acceptable solutions<br />

to common problems. One aim is to reduce<br />

unnecessary demands on hospital-based care,<br />

including admissions.<br />

Despite the importance <strong>of</strong> reducing hospital<br />

admissions, there has been little research examining<br />

variations in hospital admission rates between<br />

general practices. While studies <strong>of</strong> medical prac-<br />

tice variation are well documented in primary<br />

and secondary care, both in <strong>New</strong> <strong>Zealand</strong> 3–6 and<br />

elsewhere, 7–8 there has been little research that<br />

has specifically examined links between the two.<br />

That which has been conducted suggests that<br />

sociodemographic characteristics <strong>of</strong> practices explained<br />

most <strong>of</strong> the variation in overall admission<br />

rates and that the general practice characteristics<br />

considered added very little. 9–10<br />

If variation in admission rates cannot be accounted<br />

for by differences in patient morbidity,<br />

then questions arise regarding equity <strong>of</strong> access to<br />

hospital care, appropriateness <strong>of</strong> hospital referrals<br />

and admissions and the effectiveness <strong>of</strong> primary<br />

care. Given the recent emergence <strong>of</strong> Primary<br />

Health Organisations (PHOs) in <strong>New</strong> <strong>Zealand</strong>,<br />

While studies <strong>of</strong> medical practice variation are<br />

well documented in primary and secondary<br />

care, both in <strong>New</strong> <strong>Zealand</strong> and elsewhere,<br />

there has been little research that has<br />

specifically examined links between the two<br />

with their increased focus on equity <strong>issue</strong>s in<br />

health policy, 11 it is imperative that research<br />

investigates such variations.<br />

This study is part <strong>of</strong> a larger set <strong>of</strong> studies examining<br />

relationships between primary and secondary<br />

care in Partnership Health general practices.<br />

<strong>The</strong>se include studies <strong>of</strong> the quality <strong>of</strong> PHO data<br />

compared with hospital data, 12 <strong>of</strong> hospital general<br />

practice/hospital data on cardiological services<br />

especially related to Maori, 13 and <strong>of</strong> ambulatory<br />

sensitive hospitalisations. 14<br />

With such considerations in mind, this paper has<br />

three main objectives:<br />

• To examine the extent <strong>of</strong> the variation in hospital<br />

discharge rates between general practices.<br />

• To determine the extent to which this variation<br />

can be explained by patient characteristics,<br />

in particular deprivation and ethnicity.<br />

• To determine the extent to which special<br />

access funding is associated with<br />

practice need characteristics and increased<br />

risks <strong>of</strong> hospitalisation.<br />

Methods<br />

<strong>The</strong> study is based on patient enrolment data<br />

provided by Partnership Health, which represents<br />

approximately 75% <strong>of</strong> the Canterbury district<br />

population and is the largest PHO in <strong>New</strong><br />

<strong>Zealand</strong>, with an enrolled population <strong>of</strong> 345 254<br />

in 2007 including 19 712 Maori and 6974 Pacific<br />

people. It has over 100 general practices based in<br />

Christchurch and Selwyn. 15 It has a broadly-based<br />

governance structure with strong representation<br />

from community groups including Maori and<br />

Pacific people.<br />

Partnership Health, in conjunction with Pegasus<br />

Health, has established a comprehensive practicebased<br />

database <strong>of</strong> its enrolled patients. <strong>The</strong><br />

almost complete recording <strong>of</strong> patients’ National<br />

Health Index (NHI) numbers is a key part <strong>of</strong> this<br />

database and enables linkages to be researched between<br />

this database and hospital discharges from<br />

data held by the <strong>New</strong> <strong>Zealand</strong> Health Information<br />

Service (NZHIS).<br />

Enrolment data for Partnership Health were<br />

provided by Pegasus Health. This included the<br />

NHI numbers for all patients enrolled to which<br />

was attached data relating to practice <strong>of</strong> enrolment,<br />

date <strong>of</strong> birth, gender, ethnicity, deprivation<br />

scores, High Use Health Cards (HUHCs)—a<br />

subsidy related to need for high use <strong>of</strong> general<br />

practice consultations—and Care Plus—a subsidy<br />

for patients with chronic conditions. <strong>The</strong> date <strong>of</strong><br />

the data set was October 2007.<br />

<strong>The</strong> data were sent directly to the NZHIS by<br />

Pegasus Health. <strong>The</strong> NHI was used to link<br />

the Partnership Health enrolment data to the<br />

National Minimum Data Set (NMDS) for all<br />

hospital discharges totalling 127 246 for those<br />

enrolled for the 2½ years ending 30 June 2007.<br />

<strong>The</strong> data added to the Partnership Health data set<br />

included ethnicity, and all the other variables associated<br />

with a hospital discharge including date<br />

<strong>of</strong> admission and discharge and diagnosis. <strong>The</strong><br />

linked data from NZHIS was returned to the re-<br />

searchers with the NHIs encrypted. <strong>The</strong> NMDS<br />

data analysed were based upon the discharges <strong>of</strong><br />

all patients enrolled with Partnership Health over<br />

the two years ending 30 June 2007.<br />

In addition to calculating annual admission rates<br />

for age, gender, ethnicity, deprivation (meshblock<br />

domicile), HUHCs and Care Plus, crude annual<br />

rates were calculated for each general practice.<br />

<strong>The</strong>se are defined as the total number <strong>of</strong> admissions<br />

for each general practice per year per 1000<br />

patients registered at that practice. Rates were<br />

calculated for all 102 practices for which data<br />

were available.<br />

<strong>The</strong> association between admission rates and<br />

possible explanatory factors was investigated<br />

via stepwise multiple regression analysis. <strong>The</strong><br />

analyses <strong>of</strong> admission rates were undertaken as<br />

follows: First, controls were made for practice<br />

variations in age and sex by entering these into<br />

the model followed by other practice population<br />

variables, including deprivation, percentage<br />

Maori, percentage Pacific and percentage Asian<br />

patients. Second, the same process was then repeated<br />

using age/sex and other practice characteristics.<br />

<strong>The</strong> latter included practice size (number<br />

<strong>of</strong> enrolled patients), average number <strong>of</strong> patients<br />

per GP and the proportion <strong>of</strong> practice populations<br />

enrolled in Care Plus and with HUHCs. Third,<br />

all practice characteristics were included in the<br />

final model. Separate analyses were conducted for<br />

total, European and Maori patients.<br />

For the analyses predicting practice variations<br />

in the take-up <strong>of</strong> Care Plus, and in the use <strong>of</strong><br />

HUHCs, all variables were included in stepwise<br />

models, for total, European and Maori patients.<br />

<strong>The</strong> analyses were conducted with SPSS for Windows<br />

Version 15.<br />

Results<br />

Practice variations in discharge rates<br />

Figure 1 indicates extensive variation in crude<br />

discharge rates between practices. Crude discharge<br />

rates/1000 ranged from a low <strong>of</strong> 74/1000<br />

to 353/1000 around the mean <strong>of</strong> 184/1000<br />

(SD=38.0). <strong>The</strong> important question is, thus, to<br />

what extent can this variation be explained by<br />

WHAT GAP THIS FILLS<br />

What we already know: Despite the improving quality <strong>of</strong> general practice<br />

enrolment data, very little analysis has been undertaken to explore the<br />

use <strong>of</strong> the data in linking primary and secondary care utilisation.<br />

What this study adds: A new approach to analysis using the National<br />

Health Index numbers to link general practice data with other data sources,<br />

including national data on deprivation and ethnicity, demonstrates how primary<br />

health organisation data can reliably contribute to a district database.<br />

variation in practice populations or by other practice<br />

characteristics?<br />

Table 1 presents the results <strong>of</strong> the stepwise<br />

regression models containing age and other<br />

practice population characteristics. Three practice<br />

population characteristics emerged as significant<br />

predictors <strong>of</strong> total discharges: mean deprivation,<br />

Maori ethnicity and the percentage <strong>of</strong> Asian<br />

patients, the presence <strong>of</strong> whom tended to reduce<br />

admission rates. Similar results were obtained for<br />

European but not for Maori patients. Here both<br />

predictors were different and the cumulative R 2<br />

was much lower than for the other two models<br />

(0.271 vs 0.558 and 0.583). Also it is interesting<br />

that European discharge rates were higher in<br />

practices with a higher proportion <strong>of</strong> Maori (even<br />

after accounting for deprivation) and Maori rates<br />

were also high in practices with more European<br />

and Pacific patients, although the effect <strong>of</strong> these<br />

factors was small compared to the effects <strong>of</strong> deprivation.<br />

Nevertheless, what is important is that<br />

ethnic mix had effects independent <strong>of</strong> deprivation<br />

in all three models.<br />

While there was a significant relationship, after<br />

controlling for age and sex, between the proportion<br />

<strong>of</strong> patients enrolled in Care Plus and<br />

hospitalisation rates, the effect disappeared when<br />

further controls were made for deprivation and<br />

other practice population characteristics.<br />

Practice variations in enrolment in Care Plus<br />

Partnership Health patients enrolled in Care<br />

Plus and with HUHCs have much higher<br />

discharge rates than those without, with the<br />

former being 2.9 times more likely to experience<br />

a hospital episode and the latter 4.2 times<br />

(Table 2). However, the question arises as to the<br />

extent to which GP practices vary in the extent<br />

to which they have developed chronic patient<br />

care programmes, like Care Plus, compared to<br />

HUHCs which is a subsidy approach tied to the<br />

number <strong>of</strong> GP visits.<br />

Even more so than for discharge rates, Figure 2<br />

indicates a considerable variation between<br />

practices in patient enrolment in Care Plus. Just<br />

over half <strong>of</strong> the Partnership Health practices had<br />

enrolment rates <strong>of</strong> less than 1%, while 12 practices<br />

had rates <strong>of</strong> enrolment over 5% and seven <strong>of</strong><br />

these were over 10%.<br />

Of the practice population and other characteristics,<br />

only the former help predict practice variations<br />

in Care Plus enrolment. For all patients,<br />

the percentage <strong>of</strong> Maori and the percentage aged<br />

75 years and over are the main predictors. This<br />

is also true for European patients, while for<br />

Maori only the percentage <strong>of</strong> Maori in a practice<br />

emerged as a significant predictor. Other variables,<br />

such as practice size, were not significant.<br />

For HUHCs the results (not shown) are similar,<br />

with older patients and deprivation being the<br />

main predictors in all three models (R 2 <strong>of</strong> 0.251,<br />

0.313 and 0.124 respectively).<br />

Discussion<br />

<strong>The</strong>re are two important findings <strong>of</strong> this<br />

research. First, the study confirms substantial<br />

variations in discharge rates between general<br />

practices in the Partnership Health PHO, with<br />

the highest rates more than double those <strong>of</strong> the<br />

lowest. <strong>The</strong> mean admission rate <strong>of</strong> 184 per 1000<br />

is almost identical to that reported by an English<br />

study. 9 Thus, while the level <strong>of</strong> practice variation<br />

in the current study is not unexpected, it is important<br />

because <strong>of</strong> the need to better understand<br />

ORIGINAL SCIENTIFIC PAPErS<br />

quantitative research<br />

the reasons for such differences. <strong>The</strong>re is no<br />

universal standard on what constitutes a normal<br />

range <strong>of</strong> practice variation in admission rates, but<br />

clearly in an era <strong>of</strong> fiscal constraints and limits<br />

on the ability <strong>of</strong> hospitals to provide patient care,<br />

increasing our understanding <strong>of</strong> patient pathways<br />

to hospital and the role <strong>of</strong> GPs as ‘gatekeepers’<br />

would seem to be a high priority.<br />

Figure 2. Practice variations in enrolment in Care Plus<br />

While, as in other studies, 9–10 practice population<br />

characteristics were found to be the most significant<br />

factors explaining practice differences in<br />

discharge rates, these factors explained only 63%<br />

<strong>of</strong> the variation in total discharge rates, 58% <strong>of</strong><br />

the variation in European rates, but only 26% <strong>of</strong><br />

the variation in Maori rates. Other measures <strong>of</strong><br />

primary care service provision, such as practice,<br />

were insignificant. Substantial variation therefore<br />

remained.<br />

<strong>The</strong> most likely explanation, as suggested by<br />

the numerous studies <strong>of</strong> medical practice variation,<br />

which is ubiquitous in the health sector, is<br />

general practitioner variability in the assessment<br />

and treatment <strong>of</strong> patients. Variations in clinical<br />

decision-making could occur for a variety <strong>of</strong><br />

reasons, including uncertainty in diagnoses, 14<br />

which is associated with higher rates <strong>of</strong> investigations<br />

and follow-up and increased chances <strong>of</strong><br />

referral to hospital. 15 Pressure from patients, 16 GP<br />

relationships with local specialists 9 or patterns<br />

<strong>of</strong> social exclusion in primary care have also<br />

been suggested as contributory factors. With<br />

respect to the latter, overseas research indicates<br />

that the quality <strong>of</strong> care, especially in terms <strong>of</strong><br />

consultation time, is less in more disadvantaged<br />

practices. 17–18 While GP utilisation rates for<br />

deprived groups have increased in recent years, 11<br />

if social and ethnic variation exists in the quality<br />

<strong>of</strong> treatment provided to patients by GPs,<br />

then unmet need is likely to result in increased<br />

hospitalisation. This may well be one factor<br />

leading to relatively high rates <strong>of</strong> hospitalisation<br />

among Maori attending less deprived practices<br />

and why there was a lack <strong>of</strong> any clear relationship<br />

between practice deprivation and Maori<br />

hospitalisation rates.<br />

<strong>The</strong> second important finding <strong>of</strong> this research<br />

is the independent and <strong>of</strong>ten divergent effect <strong>of</strong><br />

ethnicity on hospitalisation rates. While Maori<br />

had the highest rates <strong>of</strong> admission, these were<br />

quantitative research<br />

inadequately explained by social demographic<br />

characteristics—in particular, deprivation. By<br />

contrast, after controlling for age, sex and<br />

deprivation, practices with larger Asian populations<br />

had much lower rates <strong>of</strong> hospitalisation.<br />

<strong>The</strong>se ethnic differences cannot be attributed to<br />

deprivation, but rather likely reflect the influence<br />

<strong>of</strong> other factors such as cultural variations<br />

in individual lifestyles, differences in dietary<br />

behaviour—the latter perhaps reflecting the<br />

length <strong>of</strong> residence <strong>of</strong> Asian immigrant groups in<br />

<strong>New</strong> <strong>Zealand</strong> (the ‘migrant’ effect). Better access<br />

to primary care on the part <strong>of</strong> Asian patients may<br />

also be a contributory factor.<br />

<strong>The</strong> third important finding is that the uptake<br />

<strong>of</strong> Care Plus is relatively incomplete and highly<br />

variable between practices. <strong>The</strong>se variations were<br />

only partly accounted for by age and ethnicity,<br />

but most <strong>of</strong> the practice variation in enrolment<br />

was unexplained by practice population characteristics.<br />

This is an important finding given<br />

In light <strong>of</strong> these findings, we suggest that there<br />

are three areas in particular where further<br />

research is necessary. First, with respect to local<br />

practice variations in admissions, it would be<br />

desirable to undertake a more in-depth study <strong>of</strong><br />

GP referral decisions in high and low income<br />

practices. Increased understanding <strong>of</strong> the referral<br />

process and the organisational environments<br />

affecting GPs’ ‘gatekeeping’ role would seem to<br />

be a high priority, especially given some research<br />

showing that a relatively high proportion <strong>of</strong><br />

referrals may be inappropriate. 20 A start has been<br />

made in this regard by examining patterns <strong>of</strong><br />

avoidable hospitalisation, 21 since this factor has<br />

been used extensively as an indicator <strong>of</strong> access<br />

to, and the overall effectiveness <strong>of</strong>, primary<br />

health care.<br />

Second, particular attention is needed to address<br />

ethnic variations in admission rates between<br />

practices and particularly why there is little <strong>of</strong><br />

a social gradient in Maori rates <strong>of</strong> hospitalisa-<br />

Increased understanding <strong>of</strong> the referral process and the organisational<br />

environments affecting GPs’ ‘gatekeeping’ role would seem to be a<br />

high priority, especially given some research showing that a relatively<br />

high proportion <strong>of</strong> referrals may be inappropriate<br />

the high hospitalisation rates <strong>of</strong> Care Plus (and<br />

HUHC) patients. For example, a previous study<br />

based in Christchurch South Health Centre 19<br />

showed that the 8.6% <strong>of</strong> patients with an HUHC<br />

generated 31.5% <strong>of</strong> discharges, 42.4% <strong>of</strong> bed days<br />

and had a longer average length <strong>of</strong> stay. Identifying<br />

such patients and ensuring that appropriate,<br />

more intensive, care is provided may be a<br />

strategy to significantly reduce their impact upon<br />

hospital services.<br />

Finally, GP practices with higher rates <strong>of</strong> enrolment<br />

in Care Plus did not have lower rates <strong>of</strong><br />

hospitalisation. This may be due to improved<br />

monitoring <strong>of</strong> conditions and a greater likelihood<br />

<strong>of</strong> arranged admissions among a group <strong>of</strong><br />

patients who previously were less likely to access<br />

primary care.<br />

tion. Thirdly, with respect to Care Plus, further<br />

work is needed to assess why patient enrolment<br />

in this programme has been so low and<br />

why so much variation occurs across individual<br />

practices. Also, given the cross-sectional nature<br />

<strong>of</strong> this study, it was not possible to assess the<br />

longer-term implications <strong>of</strong> Care Plus on hospitalisation<br />

rates.<br />

This study suggests that GP practices exhibit<br />

considerable variation in patterns <strong>of</strong> hospital<br />

admission and that practice population characteristics<br />

are particularly important in explaining<br />

this. Nevertheless, some <strong>of</strong> the variation can also<br />

be attributed to other practice characteristics, in<br />

particular the availability <strong>of</strong> special need funding<br />

designed to limit hospitalisation rates among<br />

older and more deprived patients.<br />

quantitative research<br />

In the light <strong>of</strong> these results, and in view <strong>of</strong><br />

the recent development <strong>of</strong> PHO performance<br />

measures, 15 we suggest that particular attention<br />

is needed to address variation between practices,<br />

especially in terms <strong>of</strong> ethnic differences in admission<br />

rates and in the uptake <strong>of</strong> access funding<br />

which appears to be inequitable.<br />

We suggest that health services research, while it<br />

has studied either primary or secondary care, has<br />

largely ignored the interface between these two<br />

sectors. In view <strong>of</strong> the development <strong>of</strong> integrated<br />

and managed care models <strong>of</strong> primary health care<br />

in many countries over the last decade, 11 this<br />

is an important omission in such studies and<br />

one that needs to be rectified if we are to have<br />

a fuller understanding <strong>of</strong> spatial and temporal<br />

trends in hospitalisation.<br />

ABSTRACT<br />

Introduction: In line with Wagner’s Chronic Care Model, the Patient Assessment <strong>of</strong> Chronic Illness<br />

Care (PACIC) has been developed to evaluate chronic illness care delivery from the patient's perspective.<br />

Modification <strong>of</strong> the instrument to assess the same aspects <strong>of</strong> care delivery from the health practitioner’s<br />

perspective would enable individual practitioners to evaluate their own provision <strong>of</strong> self-management<br />

support, and would also enable a more direct comparison between care provided and care received<br />

within the chronic illness context.<br />

Aim: To explore the potential <strong>of</strong> a modified PACIC instrument to assess individual health practitioners’<br />

delivery <strong>of</strong> care to chronic illness patients with a sample <strong>of</strong> primary health care nurses.<br />

Methods: Seventy-seven primary care nurses completed the modified PACIC, reworded to ask about<br />

care provision rather than receipt <strong>of</strong> care. An additional seven cultural sensitivity items were included, as<br />

were questions about the suitability <strong>of</strong> the types <strong>of</strong> chronic illness care and who should be providing the<br />

care.<br />

Results: <strong>The</strong> modified PACIC items appear to be appropriate for use with health practitioners. Agreement<br />

that the types <strong>of</strong> care described in the PACIC should be provided was almost unanimous, and the<br />

predominant view was that self-management support should be provided by both nurses and doctors.<br />

Mean scale scores were higher than those generally reported from studies using the PACIC.<br />

Discussion: <strong>The</strong> results <strong>of</strong> this first evaluation <strong>of</strong> a modified PACIC suggest that the original items<br />

plus the cultural sensitivity items can be used to assess self-management support by individual health<br />

practitioners.<br />

Introduction<br />

<strong>The</strong> Chronic Care Model (CCM) developed by<br />

Wagner and colleagues at the MacColl Institute<br />

1,2 has received considerable attention in<br />

recent years as a suitable framework for delivery<br />

<strong>of</strong> primary care to people living with chronic<br />

illness, and has been promoted in a range <strong>of</strong><br />

countries such as Australia, 3 England, 4 Scotland<br />

5 and <strong>New</strong> <strong>Zealand</strong>. 6 <strong>The</strong> model consists <strong>of</strong><br />

six components (community resources, health<br />

organisation, self-management support, delivery<br />

system design, decision support, and clinical<br />

information systems) which together encompass<br />

the health care provider, patient and community<br />

interactions necessary for planned chronic illness<br />

care. Two instruments have been developed to<br />

measure the application <strong>of</strong> the Chronic Care<br />

Model in practice: the Assessment <strong>of</strong> Chronic<br />

Illness Care (ACIC) 7 designed to be used with<br />

teams <strong>of</strong> care providers, and the Patient Assessment<br />

<strong>of</strong> Chronic Illness Care (PACIC) 8 developed<br />

for patients.<br />

Project outline<br />

As part <strong>of</strong> a larger scale study <strong>of</strong> chronic illness<br />

care provision and experience, we wanted to evaluate<br />

chronic care provision from the perspective<br />

<strong>of</strong> health care providers in one District Health<br />

Board (DHB) region <strong>of</strong> <strong>New</strong> <strong>Zealand</strong>. Recent<br />

changes in the health care system have seen the<br />

establishment <strong>of</strong> chronic care teams consisting <strong>of</strong><br />

general practitioners (GPs), practice nurses, specialist<br />

nurses and allied health practitioners such<br />

as dieticians, podiatrists, physiotherapists etc.<br />

working within Primary Health Organisations<br />

(PHOs). Our longitudinal study aims to evaluate<br />

the development <strong>of</strong> these teams. However,<br />

as the teams are only just being established, we<br />

also wanted to explore care provision from the<br />

perspective <strong>of</strong> individual practitioners and needed<br />

a suitable evaluation tool. While the ACIC is<br />

generally considered appropriate for assessing<br />

provision <strong>of</strong> care, we decided to use a modified<br />

version <strong>of</strong> the PACIC instead. <strong>The</strong>re were two<br />

rationales for this decision. Firstly, the ACIC was<br />

not considered to be the best tool for individual<br />

practitioners to use as it is designed to be completed<br />

as a result <strong>of</strong> discussion amongst a chronic<br />

care team—thus representing a team opinion.<br />

Secondly, we were interested in the possibility<br />

<strong>of</strong> obtaining responses that could be directly<br />

compared to those generated by the PACIC, thus<br />

contrasting practitioners’ and patients’ views on<br />

the same dimensions <strong>of</strong> care. Consequently we<br />

obtained permission from the MacColl Institute<br />

to modify the PACIC to suit our purposes.<br />

<strong>The</strong> Patient Assessment <strong>of</strong><br />

Chronic Illness Care (PACIC)<br />

In developing the PACIC, Glasgow and colleagues<br />

tested 46 items, originally generated by<br />

chronic illness care experts, with 130 patients. 8<br />

Twenty items were retained because they<br />

demonstrated adequate variability, were easily<br />

understood by patients and best represented<br />

the underlying constructs <strong>of</strong> the Chronic Care<br />

Model. In a study <strong>of</strong> 283 people with one or more<br />

chronic illnesses, they provided a psychometric<br />

evaluation <strong>of</strong> the PACIC. <strong>The</strong> measure was presented<br />

as having an overall score, calculated by<br />

averaging across scores on all 20 items, with good<br />

internal consistency represented by a Cronbach’s<br />

alpha <strong>of</strong> 0.93. Glasgow et al. 8 also divided the<br />

WHAT GAP THIS FILLS<br />

What we already know: <strong>The</strong> PACIC instrument has been designed to<br />

assess how well elements <strong>of</strong> Wagner’s Chronic Care Model are being met by<br />

practitioners providing chronic illness care. <strong>The</strong> instrument enables people<br />

living with chronic illness to rate the care they receive.<br />

What this study adds: This exploratory study proposes a modification<br />

and extension <strong>of</strong> the PACIC so that it can be applied to the provision <strong>of</strong> care<br />

and can be completed by an individual health practitioner. <strong>The</strong> extra items<br />

allow for the assessment <strong>of</strong> the appropriateness <strong>of</strong> chronic illness care for<br />

people <strong>of</strong> different ethnicities.<br />

items into groups <strong>of</strong> three to five, resulting in<br />

five a priori scales based on key components <strong>of</strong><br />

the CCM named Patient activation (items 1–3),<br />

Delivery system design/Decision support (items<br />

4–6), Goal setting/Tailoring (items 7–11), Problemsolving/Contextual<br />

(items 12–15) and Follow-up/<br />

Coordination (items 16–20). <strong>The</strong>se represented<br />

five <strong>of</strong> the six CCM components. <strong>The</strong> sixth was<br />

not exemplified as the authors felt that patients<br />

would be unable to report on clinical information<br />

systems or health care organisation. <strong>The</strong>y<br />

conducted a confirmatory factor analysis to evaluate<br />

the goodness <strong>of</strong> fit <strong>of</strong> the items to the scale<br />

structure and reported it to be moderate. Item 16<br />

was described as having a relatively poor fit but,<br />

as contact following a visit was considered to be<br />

essential, it was left in the measure.<br />

Since then, McIntosh 9 examined the factor<br />

structure using the items from four <strong>of</strong> the PACIC<br />

subscales with a general population, aiming to<br />

measure their experiences with the health care<br />

system. He concluded that the data better fitted a<br />

two-factor model which he labelled Whole Person<br />

Care and Coordination <strong>of</strong> Care. He acknowledged<br />

that the lack <strong>of</strong> consistency between his and<br />

Glasgow’s findings may have resulted from the<br />

sampling differences, but the other measures<br />

he tested retained their structure despite being<br />

applied to a general sample. Other authors 11 have<br />

also raised questions about the factor structure<br />

<strong>of</strong> the PACIC. While their principal components<br />

analysis suggested the existence <strong>of</strong> five factors,<br />

the items were distributed differently to how the<br />

original authors proposed.<br />

Previous modifications <strong>of</strong> the PACIC have<br />

included an extension <strong>of</strong> the measure to develop<br />

the PACIC 5As version, 10 and translations into<br />

different languages. <strong>The</strong> 5As extension was based<br />

on the 5A model <strong>of</strong> behavioural change (assess,<br />

advise, agree, assist and arrange) and involved the<br />

addition <strong>of</strong> six items which, in combination with<br />

subsets <strong>of</strong> the original 20, enabled the assessment<br />

<strong>of</strong> practitioners’ counselling aimed at improving<br />

patients’ self-management. In addition there have<br />

been translations into Spanish, 12 Dutch 11 and<br />

German 13 for use with different patient populations,<br />

but no previous attempts have been made<br />

to use the tool with health care providers.<br />

<strong>The</strong> aim <strong>of</strong> this exploratory project was to evaluate<br />

a new version <strong>of</strong> the PACIC, the focus being<br />

on content validation <strong>of</strong> the modification to see<br />

whether it is appropriate to apply the same items<br />

from the perspective <strong>of</strong> health practitioners<br />

rather than patients, as was originally intended.<br />

This included collecting participants’ views on<br />

the items included in the measure and finding<br />

out who they thought should be providing<br />

chronic illness care. For this project, the modification<br />

process involved rewording the PACIC<br />

items so that they could be used to evaluate care<br />

provided to chronic illness patients, rather than<br />

care received by them as the measure was originally<br />

intended. <strong>The</strong> new version is referred to as<br />

the modified PACIC (MPACIC).<br />

Methods<br />

Sample<br />

Using a list <strong>of</strong> regional primary care nurses held<br />

by the DHB, a questionnaire, plus an information<br />

sheet and a reply paid envelope, was posted to<br />

241 primary health nurses in the DHB region. A<br />

reminder letter was sent two weeks later. Seventy-seven<br />

(32%) questionnaires were returned. This<br />

study received ethical approval from the Central<br />

Ethics Committee.<br />

Materials<br />

<strong>The</strong> questionnaire consisted <strong>of</strong> a modified version<br />

<strong>of</strong> the PACIC. In modifying the original<br />

instrument, the content <strong>of</strong> the questions was left<br />

the same but the question stem was changed to<br />

read ‘when caring for a person with a chronic<br />

illness, how <strong>of</strong>ten do you…’ and each question<br />

was altered to fit the care provision context. An<br />

example <strong>of</strong> the item modification is as follows:<br />

Original wording:<br />

During the last six months, when receiving care for<br />

my chronic illness I was asked for my ideas when<br />

we made a treatment plan.<br />

Modified wording:<br />

When caring for a person with a chronic illness,<br />

how <strong>of</strong>ten do you ask for their ideas when making a<br />

treatment plan?<br />

<strong>The</strong> response options remained unchanged as<br />

‘almost always’, ‘most <strong>of</strong> the time’, ‘sometimes’,<br />

‘generally not’ and ‘almost never’, numerically<br />

scored as 5 to 1 respectively. <strong>The</strong> items are listed<br />

in the appendix in the web version <strong>of</strong> this paper.<br />

As well as altering the focus from care receipt to<br />

care provision, a section containing seven new<br />

items was added to address cultural sensitivity in<br />

care provision. Maori have poorer health status<br />

than non-Maori, regardless <strong>of</strong> income, educational<br />

and socioeconomic level 14 and the Ministry <strong>of</strong><br />

Health is committed to addressing health disparities<br />

following three Treaty <strong>of</strong> Waitangi (Te Tiriti<br />

o Waitangi) principles: partnership, participation<br />

and protection. 15 <strong>The</strong> seven cultural sensitivity<br />

items added to the MPACIC were developed<br />

by Maori nurses in discussion with the project<br />

advisory team. <strong>The</strong> items, following the stem, are<br />

presented below:<br />

When caring for a person with chronic illness, how<br />

<strong>of</strong>ten do you…<br />

appropriately involve the whanau/family in<br />

•<br />

the care and management <strong>of</strong> their condition?<br />

gather information or feedback from<br />

•<br />

whanau/family members?<br />

educate the whanau/family on prevention <strong>of</strong><br />

•<br />

quantitative research<br />

Two extra questions were added to each <strong>of</strong> the<br />

MPACIC items enquiring about whether the type<br />

<strong>of</strong> care outlined in the item should be provided<br />

(yes or no) and, if so, by whom (GP, nurse or<br />

both). <strong>The</strong> first was done partly as a validation <strong>of</strong><br />

the content <strong>of</strong> the PACIC since if the respondents<br />

did not see some type <strong>of</strong> care as being important<br />

they would presumably not be providing<br />

it. <strong>The</strong> second addition was included in order to<br />

explore the ‘division <strong>of</strong> labour’ notion <strong>of</strong> a team<br />

approach to chronic illness care. It was thought<br />

that views may differ on who was responsible for<br />

providing certain types <strong>of</strong> care, with a possible<br />

consequence being that some types were being<br />

neglected as different types <strong>of</strong> health practitioners<br />

thought somebody else was, or should be,<br />

taking responsibility.<br />

Data analysis<br />

Responses were entered into SPSS for Windows<br />

Version 15.0 and analyses included examination<br />

<strong>of</strong> item distributions, total scale means, and interitem<br />

correlations.<br />

Results<br />

MPACIC (20 items)<br />

Examination <strong>of</strong> the item frequencies showed<br />

that most items had either a normal or negatively<br />

skewed distribution, suggesting that most<br />

nurses rated their chronic illness care neutrally<br />

or positively. This picture was borne out by the<br />

mean item scores which ranged (out <strong>of</strong> a possible<br />

score <strong>of</strong> 5) from 3.42 for ‘provide a written list<br />

<strong>of</strong> things they should do to improve their health’<br />

to 4.52 for ‘consider their values and traditions<br />

when recommending treatments’. <strong>The</strong> mean total<br />

PACIC scores ranged from 2.3 to 4.9 out <strong>of</strong> a possible<br />

5, with a mean score <strong>of</strong> 3.99. This equates to<br />

care being provided most <strong>of</strong> the time on average.<br />

<strong>The</strong>re were very little missing data and what<br />

was missing resulted from a range <strong>of</strong> people not<br />

answering an item rather than one or two people<br />

not responding to several items.<br />

Pearson’s correlations between items ranged<br />

from 0.02 to 0.70 with the majority <strong>of</strong> correlations<br />

being in the low moderate range (mean<br />

r=0.34). Cronbach’s alpha for the total scale was<br />

0.91 and although this would not improve if any<br />

individual items were removed, examination <strong>of</strong><br />

the corrected item-total and squared multiple<br />

correlations suggested that items 16 and 18 were<br />

contributing less to the total scale than the other<br />

items. Both <strong>of</strong> these items demonstrated limited<br />

variability and were more weakly correlated with<br />

the other items.<br />

<strong>The</strong> seven new items received mean scores<br />

between 3.53 and 3.92, and correlations between<br />

items ranged from 0.15 to 0.73. <strong>The</strong> most<br />

strongly correlated items were the first two,<br />

both relating to involvement <strong>of</strong> family/whanau<br />

in chronic illness management. Despite the correlation<br />

being relatively strong, the distributions<br />

were different, and the pattern <strong>of</strong> correlations<br />

with other cultural sensitivity items, while being<br />

in the same strength range, were not identical.<br />

When these seven new items were combined<br />

with the other 20 MPACIC items, the range<br />

<strong>of</strong> scale scores was similar, ranging from 2.33<br />

to 4.85 with a mean score <strong>of</strong> 3.94. Cronbach’s<br />

alpha for the extended scale was 0.93. One <strong>of</strong><br />

these new items (number 5) had a relatively low<br />

corrected item-total correlation when compared<br />

to the other items and again displayed slightly<br />

more limited variability.<br />

As this was an exploratory project, space was provided<br />

for respondents to supplement their ratings<br />

with any comments or feedback they wanted to<br />

provide. <strong>The</strong> strongest message arising from the<br />

additional comments was that the care provided<br />

needed to be suited to the individual concerned,<br />

for example ‘this is done when appropriate, it<br />

depends on where the person is on their health<br />

journey at that time’. Similarly, a number <strong>of</strong> comments<br />

related to things being done sometimes<br />

but not at every appointment, for example ‘(this)<br />

may not be done at every consultation but is an<br />

integral part <strong>of</strong> ongoing care’.<br />

Appropriateness <strong>of</strong> care<br />

As stated earlier, two additional questions were<br />

tagged onto the PACIC items; whether the care<br />

should be provided for people with a chronic<br />

illness and, if so, by whom. <strong>The</strong> agreement that<br />

the types <strong>of</strong> care itemised should be provided was<br />

almost unanimous, with 15 <strong>of</strong> the 20 original<br />

items and four <strong>of</strong> the seven new items receiving<br />

100% support. <strong>The</strong> lowest support was provided<br />

for the screening <strong>of</strong> whanau/family where appropriate,<br />

but only two respondents (2.2%) disagreed<br />

that this should be provided.<br />

In terms <strong>of</strong> who should be providing chronic<br />

illness care ‘both GPs and nurses’ was the<br />

predominant response. All but one <strong>of</strong> the items<br />

(number 16) received this response from at least<br />

50 (72.5%) <strong>of</strong> the nurses; 29 (32.6%) felt that it<br />

was the responsibility <strong>of</strong> both GPs and nurses<br />

to contact people after a visit to see how things<br />

were going, but 44 (49.4%) considered this to be<br />

for nurses rather than GPs to carry out. In general,<br />

support for the itemised types <strong>of</strong> care being<br />

specifically part <strong>of</strong> the nurse’s role ranged from<br />

1.4% to 60.3% (one to 53 respondents). Support<br />

for types <strong>of</strong> care being specifically part <strong>of</strong> the<br />

whether the types <strong>of</strong> self-management care covered<br />

by its items are being provided by nurses<br />

for the people with chronic illness whom they<br />

see in primary practice.<br />

From the MPACIC total score it was clear that<br />

the nurses in this study perceived themselves as<br />

providing a better level <strong>of</strong> care than the patients<br />

in previous studies have indicated that they are<br />

receiving. <strong>The</strong> mean score was higher than those<br />

found with the PACIC in research with patients<br />

with various chronic conditions, 8 with diabetes<br />

10,16,17 or with osteoarthritis. 13<br />

<strong>The</strong> importance <strong>of</strong> providing health care that is<br />

appropriate and sensitive to patients’ ethnicity<br />

through the cultural competence <strong>of</strong> practitioners<br />

is widely documented as a way <strong>of</strong> decreasing<br />

inequalities in health care and reducing health<br />

<strong>The</strong> Chronic Care Model promotes provision <strong>of</strong> chronic illness care<br />

that requires a transformation <strong>of</strong> the health care system in order to<br />

provide proactive care aimed at keeping people healthy rather than<br />

acute, reactive care provided once symptoms have taken hold and<br />

people are no longer managing<br />

GP’s role ranged from 0% to 4.5% (zero to four<br />

respondents) with the highest support indicated<br />

for the screening <strong>of</strong> family/whanau being part<br />

<strong>of</strong> the GP role, although another four (4.5%) felt<br />

it should be performed by nurses and 81 (91.0%)<br />

by both.<br />

Discussion<br />

<strong>The</strong> Chronic Care Model promotes provision<br />

<strong>of</strong> chronic illness care that requires a transformation<br />

<strong>of</strong> the health care system in order to<br />

provide proactive care aimed at keeping people<br />

healthy rather than acute, reactive care provided<br />

once symptoms have taken hold and people are<br />

no longer managing. <strong>The</strong> ACIC and PACIC<br />

instruments have been designed with patient<br />

self-management as a primary focus and this<br />

study has adapted the PACIC in order to assess<br />

disparities. 18–19 <strong>The</strong> additional seven items designed<br />

to address cultural sensitivity in chronic<br />

illness care appeared to work well and may add<br />

a useful dimension to measurement in this area<br />

where people <strong>of</strong> various ethnicities are part <strong>of</strong> the<br />

patient population.<br />

This paper has considered the individual items <strong>of</strong><br />

the MPACIC and has combined them as an overall<br />

scale. Subscale scores are reported in a separate<br />

paper. 20 Future work with a larger sample should<br />

be conducted to enable analysis <strong>of</strong> the potential<br />

factor structure <strong>of</strong> the items. Inclusion <strong>of</strong> other<br />

primary care practitioners such as general practitioners<br />

would also be advisable.<br />

<strong>The</strong> results <strong>of</strong> this first application <strong>of</strong> a modified<br />

PACIC suggest that the items can be used to<br />

assess chronic illness care provision by individual<br />

health practitioners, and that the content <strong>of</strong> the<br />

items was considered an appropriate part <strong>of</strong> both<br />

nurses’ and general practitioners’ roles. Due to<br />

the small number <strong>of</strong> respondents we were unable<br />

to examine any underlying structure <strong>of</strong> the<br />

items and further work with a larger sample is<br />

needed with respect to this. <strong>The</strong> modified instrument<br />

may add useful information to that gained<br />

from application <strong>of</strong> the PACIC and ACIC when<br />

evaluating care provision for people living with<br />

chronic illness and could enable a comparison between<br />

the care practitioners consider themselves<br />

to be providing and that which patients report<br />

they are receiving.<br />

ABSTRACT<br />

Introduction: Providing care for people with chronic illness is a major <strong>issue</strong> for health practitioners<br />

around the world, especially as populations age. Encouraging self-management is beneficial in terms <strong>of</strong><br />

relieving the burden on the health system and promoting better health and adherence to medication and<br />

advice amongst this group.<br />

Aim: To measure the level <strong>of</strong> self-management support being provided to and received by people living<br />

with chronic illness in a District Health Board (DHB) region.<br />

Methods: Self-report questionnaires (PACIC) were completed by 341 people living with chronic illness<br />

to measure the self-management support they receive from general practitioners and nurses. A modified<br />

version <strong>of</strong> the PACIC was used with 12 GPs and 77 primary health nurses in the same region to assess the<br />

provision <strong>of</strong> self-management support.<br />

Results: Patients’ assessments suggest that they are receiving intermittent self-management support<br />

for their chronic illness. A comparison <strong>of</strong> ratings <strong>of</strong> different health practitioners revealed that nurses<br />

were reported to be providing support more consistently than GPs. <strong>The</strong> health practitioners rated themselves<br />

as providing self-management support more <strong>of</strong>ten than the patients reported receiving it. Many<br />

clinicians also suggested that not all forms <strong>of</strong> support are appropriate for everyone, suggesting the need<br />

to tailor support to the individual.<br />

Discussion: Chronic illness support needs to be considered within the context <strong>of</strong> the individual and to<br />

be embedded in an ongoing relationship between the person and the provider. Findings highlight the benefits<br />

<strong>of</strong> a multidisciplinary team approach to self-management support and education in chronic illness care.<br />

Introduction<br />

Chronic conditions have been identified by<br />

the World Health Organization as the twentyfirst<br />

century health care challenge due to the<br />

escalating incidence and the social and economic<br />

costs which accompany them. In 2006<br />

the NZ National Health Committee presented<br />

a report to the Minister <strong>of</strong> Health which<br />

outlined chronic conditions as a major driver<br />

for inequalities and an area where there were<br />

significant opportunities to review and revise<br />

the nature <strong>of</strong> service provision. 1 In line with<br />

international literature, a key component <strong>of</strong><br />

that advice was a move towards increasing the<br />

capacity <strong>of</strong> people with chronic illness to better<br />

understand and manage their own conditions.<br />

This has become variously known as<br />

self-management or self-care support.<br />

ORIGINAL SCIENTIFIC PAPErS<br />

quantitative research<br />

Self-management has been defined as:<br />

1) engaging in activities that promote health, build<br />

physiologic reserve and prevent adverse sequelae; 2)<br />

interacting with health care providers and adhering<br />

to recommended treatment protocols; 3) monitoring<br />

physical and emotional status and making<br />

appropriate management decisions on the basis <strong>of</strong><br />

the results <strong>of</strong> self-monitoring; and 4) managing the<br />

effects <strong>of</strong> illness on the patient’s ability to function<br />

in important roles and on emotions, self-esteem and<br />

relationships with others. 2<br />

This suggests the need for self-management support<br />

from health pr<strong>of</strong>essionals, defined as ‘the<br />

systematic provision <strong>of</strong> education and supportive<br />

interventions to increase patients’ skills and confidence<br />

in managing their health problems, including<br />

regular assessment <strong>of</strong> progress and problems,<br />

goal setting, and problem-solving support’. 3<br />

<strong>The</strong> need for self-management is tw<strong>of</strong>old; firstly,<br />

engaging patients in the decisions and management<br />

<strong>of</strong> their condition(s) results in better<br />

adherence to medication, more positive health<br />

behaviours and better outcomes, even when<br />

treatment has proved ineffective, 4 and, secondly,<br />

self-management can reduce the strain on the<br />

health system <strong>of</strong> coping with the increasing<br />

level <strong>of</strong> chronic illness in the population. Selfmanagement<br />

is a core dimension <strong>of</strong> the Chronic<br />

Care Model 5 which is widely accepted in the US<br />

and around the world. Bodenheimer 6 suggests<br />

that the provision <strong>of</strong> self-management support<br />

requires a team approach to: giving information;<br />

teaching disease-specific skills; negotiating health<br />

behaviour change; providing training in problemsolving<br />

skills; assisting with the emotional impact<br />

<strong>of</strong> having a chronic disease; providing regular<br />

and sustained follow-up and encouraging active<br />

participation in the management <strong>of</strong> the disease.<br />

<strong>The</strong> aim <strong>of</strong> this study was to measure the level <strong>of</strong><br />

self-management support being provided for and<br />

received by people living with chronic illness in<br />

the MidCentral DHB region. Here we report on<br />

the completed first phase <strong>of</strong> a two-phase study.<br />

Phase one will be replicated 15 months later to<br />

assess naturally occurring developments in recognition<br />

that this is an area <strong>of</strong> ongoing learning and<br />

development for primary health care services.<br />

WHAT GAP THIS FILLS<br />

What we already know: Facilitating self-management is an important<br />

aspect <strong>of</strong> chronic illness care, both to decrease demands on the health<br />

system and to improve patient outcomes. Previous research has explored the<br />

support provided by health practitioners, but little consideration has been<br />

given to how the impact <strong>of</strong> that support might differ when provided by health<br />

practitioners from different disciplines.<br />

What this study adds: This study shows that nurses are perceived to<br />

provide more self-care support than GPs. A multidisciplinary team approach<br />

to the provision <strong>of</strong> chronic illness care is likely to best meet the needs <strong>of</strong> individuals<br />

living with chronic illness.<br />

Methods<br />

Sample<br />

In this study, two sets <strong>of</strong> data were collected; one<br />

from people living with one or more chronic illness/es,<br />

the other from general practitioners (GPs)<br />

and primary health nurses providing chronic<br />

illness care. <strong>The</strong> patient sample was recruited by<br />

sending letters <strong>of</strong> invitation; firstly to all who<br />

had attended any ambulatory chronic illness<br />

clinic during the previous 18 months, secondly<br />

via a company managing health services provided<br />

through Primary Health Organisations (PHOs)<br />

in the community, and thirdly through a Maori<br />

health provider. From these invitations we received<br />

400 expressions <strong>of</strong> interest. Surveys were<br />

sent out to this group and 341 usable forms were<br />

returned. This reflects a response rate <strong>of</strong> 85.3%<br />

from the expression <strong>of</strong> interest pool. For the clinician<br />

sample, letters <strong>of</strong> invitation and questionnaires<br />

were also sent to GPs and primary health<br />

nurses in the DHB and 89 were returned—77<br />

from nurses and the remainder from GPs.<br />

Materials and procedure<br />

<strong>The</strong> Patient Assessment <strong>of</strong> Chronic Illness Care<br />

(PACIC) 7 was used to measure self-management<br />

support. This 20 item self-report questionnaire<br />

was designed to evaluate five types <strong>of</strong> selfmanagement<br />

support representing five <strong>of</strong> the six<br />

aspects <strong>of</strong> the Chronic Care Model. <strong>The</strong> items<br />

have consequently been developed to provide a<br />

total scale and five subscales which, according to<br />

the authors, are defined as follows: Patient activation<br />

involves actions that solicit patient input and<br />

involvement in decision-making; Delivery system<br />

design/Decision support includes actions that<br />

organise care and provide information to patients<br />

to enhance their understanding <strong>of</strong> care; Goal<br />

setting/Tailoring means acquiring information for<br />

and setting <strong>of</strong> specific collaborative goals; Problem<br />

solving/Contextual is represented by considering<br />

potential barriers and the patient’s social and<br />

cultural environment in making treatment plans;<br />

and Follow-up/Coordination involves arranging<br />

care that extends and reinforces <strong>of</strong>fice-based<br />

treatment, and making proactive contact with<br />

patients to assess progress and coordinate care. 7<br />

<strong>The</strong> PACIC requires respondents to rate the<br />

frequency with which certain types <strong>of</strong> care are<br />

provided on a 5-point scale ranging from ‘almost<br />

always’ to ‘almost never’, numerically scored as 5<br />

to 1 respectively.<br />

Two sample questions are:<br />

During the last 12 months when receiving care for<br />

my chronic illness, I was…<br />

…helped to make plans for how to get support from<br />

my friends, family or community.<br />

…sure that the health pr<strong>of</strong>essional thought about<br />

my values and my traditions when they recommended<br />

treatments to me.<br />

Scores are averaged to provide a total and subscale<br />

scores within the range <strong>of</strong> 1 to 5. With respect<br />

to internal consistency <strong>of</strong> the scales, Cronbach’s<br />

alphas have been reported to range between 0.77<br />

and 0.90. 7,8<br />

In the current study, participants were asked to<br />

rate two health pr<strong>of</strong>essionals; firstly, their GP<br />

who they felt provided care in relation to their<br />

and demographic questions comprised the patient<br />

questionnaire which was posted out with a replypaid<br />

envelope to those who had responded to the<br />

letter <strong>of</strong> invitation. A reminder letter was sent<br />

to those who had not returned the questionnaire<br />

within a month.<br />

<strong>The</strong> health pr<strong>of</strong>essional questionnaire primarily<br />

consisted <strong>of</strong> a modified version <strong>of</strong> the PACIC,<br />

hereafter referred to as the MPACIC. <strong>The</strong> modification<br />

changed the question stem to fit the context<br />

<strong>of</strong> care provided rather than received in order<br />

to amend the questionnaire for use with health<br />

practitioners rather than patients. Questions<br />

about cultural sensitivity were also included.<br />

Further detail is provided elsewhere. 9<br />

Results<br />

<strong>The</strong> patients ranged in age from 23 to 93 with<br />

a mean age <strong>of</strong> 68.2. <strong>The</strong>re were slightly more<br />

men (189, 55.4%) than women; 270 (80.4%) were<br />

NZ European and 49 (14.6%) identified as Maori.<br />

Over half <strong>of</strong> the respondents (176, 58.8%) indicated<br />

they were living on less than $20,000 per<br />

annum. <strong>The</strong> chronic conditions listed were varied<br />

with just over a third <strong>of</strong> the sample (119, 35.2%)<br />

indicating they had only one condition, the other<br />

two-thirds living with two (112, 33.1%) to seven<br />

(20, 0.6%). <strong>The</strong> main conditions experienced,<br />

and the percentage <strong>of</strong> the sample affected were:<br />

cardiac (212, 62.7%), diabetes (136, 40.2%), respiratory<br />

(94, 27.8%) and pain (94, 27.8%). Ratings<br />

<strong>of</strong> the impact <strong>of</strong> their chronic illness on quality<br />

<strong>of</strong> life ranged from 0 to 10, thus representing the<br />

full scale where 0 represented no effect and 10<br />

an extreme effect, with a mean score <strong>of</strong> 6.4 and a<br />

mode <strong>of</strong> 8.0.<br />

Of the 341 patients, 307 (90%) provided ratings<br />

<strong>of</strong> a GP as health provider and 180 (52.8%)<br />

rated a nurse. As a number <strong>of</strong> participants rated<br />

both a nurse and a GP, the ratings could not be<br />

considered independent. <strong>The</strong>refore no inferential<br />

statistics are reported in this paper. <strong>The</strong> mean total<br />

presented in columns two and three <strong>of</strong> Table 1.<br />

<strong>The</strong> possible range <strong>of</strong> score was 0 to 5 and it can<br />

be seen that the range reported was from 2.3 to<br />

3.7. A comparison reveals that nurses are rated<br />

more highly than GPs on all aspects <strong>of</strong> self-management<br />

support. <strong>The</strong> magnitude <strong>of</strong> the means<br />

shows that, on average, nurses are providing selfmanagement<br />

support sometimes to most <strong>of</strong> the<br />

time whereas GPs are generally not or sometimes<br />

providing it. <strong>The</strong> fourth column provides mean<br />

scores for the health pr<strong>of</strong>essionals’ ratings <strong>of</strong><br />

their own provision <strong>of</strong> self-management support.<br />

<strong>The</strong>y ranged from 3.8 to 4.3 (possible range 0 to<br />

5) and are notably higher than the patient ratings<br />

<strong>of</strong> the support they receive. It is also apparent<br />

from comparing the rank order <strong>of</strong> the subscale<br />

scores that the aspects <strong>of</strong> self-management support<br />

provided by nurses and GPs are similarly<br />

ordered with delivery system design being rated<br />

highest for both practitioner groups and patient<br />

activation second. <strong>The</strong> only difference was the<br />

reversal <strong>of</strong> placings for the two lowest rated<br />

aspects, goal setting and follow-up. A comparison<br />

with the MPACIC scores showed that health pr<strong>of</strong>essionals<br />

considered themselves to be providing<br />

the best support in the area <strong>of</strong> patient activation<br />

with problem solving scoring second. <strong>The</strong> other<br />

three aspects were all equally rated.<br />

One hundred and twenty-two participants<br />

provided ratings <strong>of</strong> both a GP and a nurse and,<br />

within these pairs <strong>of</strong> ratings, mean PACIC scores<br />

were 2.8 and 3.2 respectively. Although the participants<br />

were asked to provide ratings <strong>of</strong> care received<br />

from two health practitioners, not all had<br />

two to rate. To see whether those with two were<br />

better <strong>of</strong>f than those with one, a comparison was<br />

made between the one score <strong>of</strong> those participants<br />

with only one chronic care provider and the best<br />

score <strong>of</strong> those with two. Results showed that the<br />

mean score was 0.3 (on a 5-point scale) higher for<br />

those with two health practitioners, typically a<br />

GP and a nurse.<br />

<strong>The</strong> health practitioners were invited to add<br />

comments to their ratings and many <strong>of</strong> the comments<br />

focussed around the notion that the types<br />

<strong>of</strong> support listed are not all appropriate for every<br />

individual, and neither are they all appropriate to<br />

provide at every meeting. 9 For this reason many<br />

health pr<strong>of</strong>essionals were choosing to provide<br />

self-management support sometimes or mostly<br />

rather than nearly always. Care Plus was cited as<br />

being an ideal way to deliver self-management<br />

support.<br />

Discussion<br />

<strong>The</strong> patient data revealed a variety <strong>of</strong> reasons<br />

why this group required self-management support.<br />

Many were living with more than one<br />

chronic illness, which was having a pronounced<br />

affect on their quality <strong>of</strong> life, in impoverished<br />

circumstances. Pain was identified as being a<br />

problem for nearly a third <strong>of</strong> the participants.<br />

We previously found that patients were keen<br />

to achieve a sense <strong>of</strong> ownership <strong>of</strong> their condition<br />

and expressed a desire to understand, plan<br />

realistically and anticipate the course <strong>of</strong> their<br />

condition. 10 Much <strong>of</strong> this was expressed as a need<br />

to have their personhood rather than their illness<br />

At the heart <strong>of</strong> self-management support is<br />

the nature and quality <strong>of</strong> communication in<br />

clinical encounters and the best use <strong>of</strong> team<br />

members to provide aspects <strong>of</strong> care<br />

as the focus <strong>of</strong> clinical encounters. Literature on<br />

self-management identifies the need for relating<br />

to individuals in terms <strong>of</strong> their personal context<br />

including the particular capacity <strong>of</strong> each individual<br />

to manage changes and demands in their life.<br />

<strong>The</strong> scores on the various aspects <strong>of</strong> self management<br />

support, as identified by the subscale<br />

groupings, show remarkable consistency across<br />

the three sets. It appears that follow-up and goal<br />

setting are the areas <strong>of</strong> self-management support<br />

that are most in need <strong>of</strong> attention within the<br />

current system. At the heart <strong>of</strong> self-management<br />

support is the nature and quality <strong>of</strong> communication<br />

in clinical encounters and the best use <strong>of</strong><br />

team members to provide aspects <strong>of</strong> care. <strong>The</strong><br />

apparent difference between how GPs and nurses<br />

were rated by chronic illness patients in this<br />

study highlights the need for a team approach to<br />

providing self-management support. As noted by<br />

Wagner, 11 much <strong>of</strong> what is needed is behavioural<br />

counselling, which may be considered outside<br />

the job description <strong>of</strong> most GPs and better suited<br />

to the nurse role in chronic care service delivery.<br />

Thus, if a proactive team-based approach<br />

is utilised, the patient should have access to a<br />

comprehensive range <strong>of</strong> primary health care clinicians<br />

who are well placed to complement the care<br />

provided by GPs and specialists.<br />

Our results suggested that, on average, patients<br />

receiving support from more than one practitioner<br />

rated the care they received more positively<br />

than those with less support. It may well be that<br />

they were being provided with different forms <strong>of</strong><br />

support from different practitioners, thus benefiting<br />

from exposure to a care team.<br />

<strong>The</strong> reported difference between the levels <strong>of</strong><br />

self-management support patients indicated they<br />

…self-management support needs to be<br />

embedded within an ongoing relationship<br />

between patient and health pr<strong>of</strong>essional;<br />

the same approach doesn’t suit everybody<br />

are receiving, and that which health pr<strong>of</strong>essionals<br />

consider themselves to be providing, is interesting.<br />

It may reflect an inconsistency between<br />

patients’ and health practitioners’ knowledge and<br />

beliefs about what constitutes care, and specifically<br />

self-management support. <strong>The</strong> findings<br />

also need to be viewed in light <strong>of</strong> the question<br />

that was being answered. Health practitioners<br />

were rating what they generally do in relation to<br />

chronic illness care; the patients were rating the<br />

self-management support they personally receive.<br />

A number <strong>of</strong> practitioners commented that some<br />

<strong>of</strong> the listed types <strong>of</strong> support were inappropriate<br />

for a number <strong>of</strong> clients or stated that they carried<br />

them out on occasion but not at every visit.<br />

This may be an example <strong>of</strong> Willis’s 12 definition<br />

<strong>of</strong> providing information which, he suggests,<br />

should not just be the transmission <strong>of</strong> facts but<br />

encompass ‘how other people have responded in<br />

a similar situation, what the impact may be on a<br />

patient’s lifestyle, or, based on our knowledge <strong>of</strong><br />

patients derived from being their family doctor,<br />

judging what they may consider appropriate’.<br />

This approach also aligns with the notion that<br />

self-management support needs to be embedded<br />

within an ongoing relationship between patient<br />

and health pr<strong>of</strong>essional; the same approach doesn’t<br />

suit everybody. 13 Enabling patients to incorporate<br />

self-management into their daily routines<br />

requires getting to know them in order to develop<br />

self-management plans collaboratively. 6 Similarly<br />

Willis 12 talked about the need for patients to have<br />

‘true autonomy’ defined as providing information<br />

they want or need, but in a form that they<br />

can understand, thus becoming partners and<br />

enabling them to self-govern. He used a rugby<br />

team analogy to highlight the importance <strong>of</strong> one<br />

person’s autonomy not being allowed to overcome<br />

another’s and this could be applied equally well to<br />

a chronic care team where the successful approach<br />

enables doctors, nurses, other health pr<strong>of</strong>essionals<br />

and patients themselves to exercise their autonomy<br />

both individually and as a team to achieve the<br />

most positive outcome for the patient.<br />

Care Plus was considered by the health pr<strong>of</strong>essionals<br />

sampled to be a useful vehicle for administering<br />

self-management support, primarily<br />

due to the time it made available for individual<br />

consultations. <strong>The</strong> programme was introduced<br />

for people with chronic conditions in July 2004,<br />

with the aims <strong>of</strong> improving chronic care management,<br />

reducing inequalities, improving primary<br />

health care teamwork and reducing service costs<br />

for high need primary care recipients. While<br />

Care Plus was not mentioned by our patient<br />

sample—perhaps because they were unaware <strong>of</strong><br />

their involvement in it—a national review <strong>of</strong> the<br />

Care Plus programme 14 found that patients felt<br />

their care to be better structured, appreciated<br />

the consultation focus on their chronic illness,<br />

had on average accessed four more consultations<br />

per annum than previously, and had mostly<br />

(80%) received a care plan. <strong>The</strong> review identified<br />

a number <strong>of</strong> barriers to the implementation <strong>of</strong><br />

Care Plus; for example remuneration, the need<br />

for extra nurses, and the space and time required,<br />

but concluded that most individuals (pr<strong>of</strong>essionals<br />

and patients) were generally supportive <strong>of</strong><br />

the programme. <strong>The</strong> few comments provided in<br />

128 VOLUME 2 • NUMBER 2 • JUNE 2010 J OURNAL OF PRIMARY HEALTH CARE

quantitative research<br />

this study concerning Care Plus suggest that it is<br />

well regarded by those implementing it, but the<br />

extent to which it is deployed in the study region<br />

is patchy.<br />

Glasgow et al. 5 quote the adage ‘what gets measured<br />

gets done’ and that was one intention <strong>of</strong><br />

the current study. It was hoped that the process<br />

<strong>of</strong> responding to questions regarding self-management<br />

support would increase awareness <strong>of</strong><br />

what such support involves and encourage health<br />

pr<strong>of</strong>essionals to reflect on, and perhaps even<br />

alter, their behaviour. <strong>The</strong> planned phase two <strong>of</strong><br />

the study will provide the opportunity to assess<br />

developments.<br />

Limitations<br />

Although there may have been some link<br />

between the data sets as some <strong>of</strong> the patients<br />

involved in the study would have been receiving<br />

care from some <strong>of</strong> the health pr<strong>of</strong>essional<br />

participants, patients were not asked to identify<br />

who they were rating by name and doctors and<br />

nurses were not required to identify themselves.<br />

It would be useful in future research to link the<br />

sets <strong>of</strong> ratings in order to identify areas <strong>of</strong> selfmanagement<br />

support where there were apparent<br />

disparities between what health pr<strong>of</strong>essionals<br />

consider themselves to be providing and what<br />

patients feel they are receiving.<br />

ABSTRACT<br />

Introduction: Empowerment is the personal and political processes patients go through to enhance<br />

and restore their sense <strong>of</strong> dignity and self-worth. However, there is much rhetoric surrounding nurses<br />

facilitating patients’ daily choices and enabling empowerment. Furthermore, there is frequently an imbalance<br />

<strong>of</strong> power sharing, with the patient <strong>of</strong>ten obliged to do what the health pr<strong>of</strong>essional wants them to do.<br />

Method: This phenomenological study describes the lived experience <strong>of</strong> patients attending an<br />

outpatient clinic <strong>of</strong> a community hospice. A qualitative study using Max van Manen’s phenomenological<br />

hermeneutic method was conducted to explore <strong>issue</strong>s surrounding empowerment and daily decisionmaking<br />

with terminally ill patients. <strong>The</strong> participants’ stories became a stimulus for learning about the<br />

complexities <strong>of</strong> autonomy and empowerment. It also engendered reflection and analysis <strong>of</strong> <strong>issue</strong>s related<br />

to power and control inequities in current nursing practices.<br />

findings: <strong>The</strong> results revealed not only the themes <strong>of</strong> chaoticum, contracting worlds and capitulation,<br />

but that health pr<strong>of</strong>essionals should be mindful <strong>of</strong> the level <strong>of</strong> control they exert. Within the palliative<br />

care setting they need to become partners in care, enhancing another person’s potential for autonomous<br />

choice.<br />

Conclusion: Empowerment must not be something that simply occurs from within, nor can it be done<br />

by another. Intentional efforts by health pr<strong>of</strong>essionals must enable terminally ill people to be able to stay<br />

enlivened and connected with a modicum <strong>of</strong> autonomy and empowerment over daily decisions, no matter<br />

how mundane or monumental they might be.<br />

Introduction<br />

<strong>The</strong>re has been little research conducted exploring<br />

terminally ill patients’ self-empowerment and<br />

decision-making within their day-to-day lives. 1<br />

Anecdotally terminally ill people tend to be treated<br />

as a homogenous group, as though they all suffer<br />

and behave in the same manner. 2,3 <strong>The</strong> end result<br />

is that the therapeutic relationship becomes a ‘one<br />

size fits all’ model, 1,4,5 which can leave the person<br />

and their family members feeling disenfranchised,<br />

frustrated and not listened to. 1 A terminally ill<br />

person’s day-to-day decisions may seem to others<br />

mundane and redundant, but being allowed to<br />

make them can <strong>of</strong>ten enable a person to continue to<br />

feel empowered, autonomous and self-willed. 6<br />

Decision-making by terminally ill adults has been<br />

described as a performance concerning autonomy<br />

that involves a variety <strong>of</strong> players. 7,8 <strong>The</strong> right to be<br />

autonomous and make decisions about their own<br />

lives is a commonly accepted ethical principle. 7<br />

However, pragmatic nursing styles that encourage<br />

‘doing for’ rather than maintaining a presence with<br />

a terminally ill person, tend to disable many autonomous<br />

decision-making abilities and processes. 8<br />

Empowerment is the personal and political processes<br />

patients go through to enhance and restore<br />

their sense <strong>of</strong> dignity and self-worth; 9 however,<br />

there is much rhetoric surrounding nurses facilitating<br />

patients’ daily choices and enabling empow-<br />

erment. 10,5 Historically nurses have been taught<br />

about the importance <strong>of</strong> autonomy in patients, 11 yet<br />

it is debatable whether consideration <strong>of</strong> empowerment<br />

is truly incorporated into practice. While the<br />

idea <strong>of</strong> empowerment is naturally appealing, its application<br />

becomes weakened because <strong>of</strong> its abstract<br />

ambiguity. 6,4,12,13 Furthermore, there is frequently<br />

an imbalance in power sharing, with the patient<br />

feeling obliged to be humble, in the process left<br />

feeling humiliated and inconsequential. 14,15<br />

This paper reports the findings <strong>of</strong> a qualitative<br />

study with the aim <strong>of</strong> exploring <strong>issue</strong>s <strong>of</strong> empowerment<br />

and daily decision-making from the<br />

perspectives <strong>of</strong> people who are terminally ill.<br />

Method<br />

It was decided that qualitative methods, using<br />

a hermeneutic approach, 15 was the best way to<br />

achieve the aims <strong>of</strong> this study. Such an approach<br />

examines and reveals the language buried within<br />

the meanings <strong>of</strong> words. <strong>The</strong> participants’ stories<br />

allowed glimpses into the lived experience <strong>of</strong> the<br />

world <strong>of</strong> people diagnosed with terminal illness.<br />

Reflections <strong>of</strong> the ‘self’ were revealed along with<br />

the subjective nature <strong>of</strong> integrity, spirituality<br />

and wholeness, thereby enabling the activity <strong>of</strong><br />

phenomenological thinking. 15<br />

Phenomenology is described as ‘being in the moment’,<br />

<strong>of</strong> living the experience with someone else<br />

and discovering something worthy <strong>of</strong> recording. 15<br />

Phenomenology is a style <strong>of</strong> thinking, as well<br />

as a philosophy, and the intention is to describe<br />

or understand a moment in someone’s life by<br />

interpreting recollections. <strong>The</strong> most natural way<br />

<strong>of</strong> doing this is to narrate from lived experience.<br />

15 By being part <strong>of</strong> the narration process, the<br />

researcher refrains from judging and concluding<br />

what is right or wrong, but rather participates in<br />

the story. Phenomenology thus systematically<br />

attempts to uncover, describe and discover the<br />

nature or essence <strong>of</strong> the experience; in this case,<br />

<strong>of</strong> living with a terminal disease. 15<br />

Fourteen participants receiving palliative care<br />

were selected and recruited by a doctor at a community<br />

hospice and invited to participate in an individual<br />

interview between May and June 2005.<br />

Five males and six females agreed to participate in<br />

What gap this fills<br />

What we already know: Decision-making for people nearing the end <strong>of</strong><br />

life is difficult for a number <strong>of</strong> reasons. Despite improvements in communication<br />

and management near the end <strong>of</strong> life, patients and their families <strong>of</strong>ten<br />

feel disempowered, vulnerable and frustrated.<br />

What this study adds: Primary health pr<strong>of</strong>essionals need to work actively<br />

towards ways <strong>of</strong> empowering people who are dying by paying attention as<br />

much to the being aspects <strong>of</strong> care as to the doing aspects. Self-reflection and<br />

positive regard within the therapeutic relationship can enhance the experience<br />

for those who are dying.<br />

the study. Ten were Anglo-European and one was<br />

<strong>of</strong> Polynesian descent. <strong>The</strong> age range was from 48<br />

to 84 years. Cancer was the primary diagnosis for<br />

10 participants, with one having heart disease. All<br />

the participants came from one small geographical<br />

area <strong>of</strong> <strong>New</strong> <strong>Zealand</strong>. Face-to-face interviews were<br />

audiotaped (once consent was gained) and later<br />

transcribed verbatim by the researcher. All <strong>of</strong> the<br />

participants had died by the time the study was<br />

written up. Pseudonyms have been used to protect<br />

the identity <strong>of</strong> the participants.<br />

<strong>The</strong> steps that guide a study undertaken using Van<br />

Manen’s approach are summarised in Table 1. Transcribing<br />

<strong>of</strong> the interviews by the researcher enables<br />

immersion in the transcripts in order to understand<br />

abstraction and develop themes that reveal phenomena<br />

through the narratives <strong>of</strong> lived experience.<br />

A commitment was made to stay close to and intimate<br />

with the original data and this was achieved<br />

through total immersion in the text—reading, listening,<br />

re-reading and reliving the memories <strong>of</strong> the<br />

interview with each <strong>of</strong> the participants. Careful<br />

line-by-line analysis revealed common themes. 15<br />

Ethical approval was gained from the University<br />

<strong>of</strong> Otago Board <strong>of</strong> Graduate Studies, Community<br />

Hospice Ethics Committee, Lower South Regional<br />

Ethics Committee, Ngai Tahu and a member <strong>of</strong><br />

the Chinese community.<br />

Findings<br />

Three key themes were identified from the data.<br />

<strong>The</strong> first relates to participants’ lived space and<br />

was called ‘chaoticum’, as the participants lived<br />

within a chaotic and complex time in their lives. 15<br />

quaLitative research<br />

<strong>The</strong> participants reported that their lives spiralled<br />

out <strong>of</strong> control after being given their diagnosis.<br />

<strong>The</strong> second theme relates to the lived body 15 and<br />

this was called ‘contracting worlds’; participants<br />

spoke <strong>of</strong> forfeiting normality as their worlds<br />

began shrinking around them in ever decreasing<br />

circles. <strong>The</strong> final theme relates to lived time 15 and<br />

was called ‘capitulation’ because the experiences<br />

revealed a time when the participants became<br />

submissive and acknowledged that their lives<br />

were coming to an end.<br />

Chaoticum<br />

<strong>The</strong> lived experience <strong>of</strong> the participants revealed<br />

a world that was, for them, a mixture <strong>of</strong> chaotic<br />

time and chaos. <strong>The</strong>ir worlds were freewheeling<br />

out <strong>of</strong> control, leaving little time to deal with<br />

things. Participants experienced disharmony,<br />

anger, disbelief, chaos and powerlessness, as this<br />

extract from the interview with Jane reveals:<br />

I’ve been given my life sentence; I know I’m going<br />

to die but it is the unknown. Am I going to get<br />

sick, what’s going to happen to me?”<br />

Sage talks about her total disbelief and anger at<br />

the doctor being honest about dying, thus capturing<br />

the conflicting emotions and needs at this<br />

time in her life:<br />

I was angry, I was bloody angry with the doctor<br />

when he told me I was going to die… I didn’t know<br />

where to start with things. <strong>The</strong>re seemed so little<br />

time to fix things you know.<br />

Table 1. Van Manen’s Phenomenology (Adapted from van Manen, 2002 23 )<br />

Two aspects <strong>of</strong> methodology<br />

1. <strong>The</strong> reduction: Bracketing or suspension <strong>of</strong> everyday ‘natural attitude’<br />

2. <strong>The</strong> vocation: Letting things ‘speak’ or be ‘heard’ through text<br />

Six empirical methods<br />

1. Describing experiences<br />

2. Gathering experiences<br />

3. Interviewing experiences<br />

4. Observing experiences<br />

5. Fictional experiences<br />

6. Imaginal experiences<br />

Furthermore, Jessica talks <strong>of</strong> living in a house<br />

that was very chaotic:<br />

It was a sick house. I would just lie on the floor…<br />

it was depressing because I couldn’t do anything<br />

about my life. We lived in a very sick messy chaotic<br />

house all <strong>of</strong> the time.<br />

Another participant, Bruce, appeared upset at the<br />

chaos that he had left for someone else to sort<br />

for him:<br />

<strong>The</strong>re is stuff at the house that someone else will<br />

have to sort because I don’t have the energy. <strong>The</strong>y<br />

will have to sort out the mess because for two<br />

months I haven’t had the energy to fix my life…<br />

Contracting worlds<br />

Participants described the way they had to give<br />

up things in their lives; the forfeitures, losses,<br />

decreasing circles and disempowerment that they<br />

experienced. Not only were their social lives contracting,<br />

but physically they were also suffering<br />

from contractures as their bodies started to change<br />

and shrink from their former self. This is captured<br />

by Virginia who felt very vulnerable and disempowered<br />

when she made trips to the clinician:<br />

I felt terribly disempowered in the hospital setting<br />

by the oncology doctors. Just going for a check up<br />

and I would come out and think God how am I supposed<br />

to keep my hopes up when there was such a<br />

grim sort <strong>of</strong> background, a feeling <strong>of</strong> abandonment<br />

and just the odd comments. I felt so very disempowered…<br />

Apart from hope. I don’t want them to<br />

take that away from me you know.<br />

Connie described how she maintained some semblance<br />

<strong>of</strong> normality as she tried to retain a belief<br />

that her world was not changing, by washing<br />

herself and undertaking other personal care:<br />

I don’t want others doing my personal stuff for me because<br />

that would mean that I was no longer a person…<br />

This is further reflected by Grace who commented:<br />

I got quite bitter for a while. This disease can let<br />

your bodily functions go a bit in front <strong>of</strong> people<br />

and I was disgusted.<br />

quaLitative research<br />

Clearly, these participants resented the way their<br />

bodies were failing and wanted to continue to<br />

care for themselves for as long as possible.<br />

Capitulation<br />

<strong>The</strong> third theme captures the participants’ understanding<br />

that they were only temporally in the<br />

world. Participants found that the closer to death<br />

they got, the more submissive they became until<br />

they finally began to make those final end <strong>of</strong> life<br />

arrangements as reflected in Virginia’s words:<br />

<strong>The</strong>re are days that I feel like I have gone back<br />

several more steps and I have to rely a lot on others<br />

now because I don’t know when my body will give<br />

out. I feel like I have to wait on other people to do<br />

my ‘stuff’ and I feel quite powerless.<br />

Bruce grieves for the loss <strong>of</strong> his past life as he<br />

gave in to his inability to manage for himself:<br />

Two months ago I was still working and now look<br />

at me I am little more than a baby.<br />

Harry was also feeling a sense <strong>of</strong> giving-up when<br />

he commented:<br />

I hated hospital. <strong>The</strong>y (nurses) woke me up every<br />

two hours shining a torch in my eyes. I couldn’t<br />

sleep all week and I am not sure why because I<br />

wasn’t dying. I hated it and I am never going back<br />

because I couldn’t do what I usually do. You are just<br />

stuck there whether you like it or not.<br />

Whilst Jane describes accepting her terminality:<br />

I’ve just dealt with the thought <strong>of</strong> dying. Tomorrow<br />

the funeral director lady is coming. I know I have<br />

got to get some things in order.<br />

Discussion<br />

Individuals make decisions based on personal<br />

strategies and judgments, influenced by biases<br />

and rules, especially when there is an unknown<br />

future ahead. 6 Decision-making, therefore,<br />

is a complex and multifaceted phenomenon.<br />

It is difficult to deconstruct an individual<br />

person’s thoughts, feelings and behaviours and<br />

match them to the different facets <strong>of</strong> decisionmaking.<br />

2 This study has allowed the words <strong>of</strong> a<br />

small number <strong>of</strong> people living with a terminal<br />

illness the chance to describe their lived<br />

experience at a particularly challenging time in<br />

their lives. Each <strong>of</strong> these experiences, and the<br />

subsequent themes that emerged, emphasise<br />

the need for empowerment, especially during<br />

the last period <strong>of</strong> life, since individuals are<br />

more likely to make decisions based on the<br />

availability <strong>of</strong> information, on instances or<br />

recent occurrences. 15<br />

Recent research indicates that terminally ill people<br />

consistently perceive that they have a less active<br />

role in their daily decisions than they desire. 5<br />

Others start making valued judgements for them,<br />

especially health pr<strong>of</strong>essionals, because they are<br />

considered to be too vulnerable, less <strong>of</strong> a person,<br />

thought to have lost the ability to think or too<br />

sick to make choices. Terminally ill adults can<br />

make decisions and do so based on a broad range<br />

<strong>of</strong> factors, such as spirituality, values and beliefs,<br />

that subsequently influence how they respond to<br />

everyday challenges. 1<br />

<strong>The</strong>re has been much criticism concerning<br />

ethical decision-making over recent years 16 as<br />

bioethical discourse has focussed on the ideal,<br />

rather than what actually happens. Many<br />

ethicists believe that only rational or logical decisions<br />

are the right ones, but attention should<br />

also be paid to ‘what genuinely moves people<br />

to act, their motivations and passions, loves and<br />

hates, hopes and fears.’ 16 In this study, this is<br />

supported by Connie’s experiences when she<br />

commented:<br />

I didn’t want people deciding for me right up until I<br />

can no longer talk.<br />

Hunsaker Hawkins 16 suggests that small clinical<br />

aphorism and literary narratives can be a powerful<br />

vehicle for moral reasoning and transporting<br />

you deep into another person’s world for a brief<br />

time. Phenomenology allows both the narrator<br />

and the reader to be transported into the narrator’s<br />

world. 15<br />

This research reminds nurses <strong>of</strong> the importance<br />

<strong>of</strong> reflecting fully on how they can help meet the<br />

wishes <strong>of</strong> a person who is terminally ill. <strong>The</strong>re is<br />

a need to ask and keep asking whilst also being<br />

prepared to listen.<br />

Each <strong>of</strong> the participants in this study wanted<br />

someone who was not constantly doing but rather<br />

listening or simply being there. This is aptly<br />

captured by Harry when he describes how he insisted<br />

that he keep to his daily schedule because<br />

without that he knew that he would just curl up<br />

and die:<br />

I didn’t want the nurses coming to my house and<br />

doing my washing or chores and I had to keep<br />

telling them this. If I want to walk half way across<br />

town with bags <strong>of</strong> laundry when the weather is<br />

wet then that’s what I want to do. <strong>The</strong>y kept trying<br />

to make me do things on their timetable but I had<br />

other ideas.<br />

When people are given a terminal diagnosis<br />

there is a point in the care continuum when<br />

these people feel abandoned by the biomedical<br />

model along with feeling a sense <strong>of</strong> not<br />

belonging. 17 Such people are different to many<br />

<strong>of</strong> our other patients because there are no<br />

happy endings, no cures or achievable health<br />

outcomes except for the desire and hope for a<br />

perceived good death. This study revealed that<br />

terminally ill patients want nurses to become a<br />

fully-engaged being when entering the therapeutic<br />

relationship, whilst at the same time to<br />

recognise that people who are dying are unique<br />

and unpredictable in terms <strong>of</strong> the connection<br />

and dependency within the nursing/patient<br />

relationship. 17<br />

Empowerment is central to decision-making<br />

and people who are seeking health care need to<br />

be enabled and empowered to make their own<br />

informed choices. 18 Health pr<strong>of</strong>essionals can<br />

never fully understand what the patient is going<br />

through, but they can ease the path by their<br />

own critical self-reflection, listening, intuitive<br />

caring and thought. 19 Illness and disease make<br />

people deviate from their chosen life path and<br />

typically the clinical world has its own customs<br />

and culture that can be difficult to understand.<br />

Throughout the terminal illness journey nurses<br />

should endeavour to enable people to remain<br />

informed and self-empowered. 17 Moral autonomy,<br />

according to Kant, is a combination <strong>of</strong> freedom<br />

and responsibility; a truly autonomous person<br />

cannot be subjected to the will <strong>of</strong> another. 6<br />

<strong>The</strong> findings from this study suggest that health<br />

pr<strong>of</strong>essionals need to think more about power and<br />

control <strong>issue</strong>s and explore how they can become<br />

partners in enhancing another person’s potential<br />

and autonomous choices. 6,8,10 Empowerment<br />

describes the intentional efforts to create a more<br />

equitable relationship and a living within someone<br />

else’s world. 19 How a patient exercises their<br />

empowerment and control depends on individual<br />

engagement, ability and ‘the adoption <strong>of</strong> a personvaluing<br />

approach’. 3<br />

For any moral engagement to work within a particular<br />

given time and space there has to be a comfortable<br />

social and emotional congruence driven<br />

by integrity and honesty. 1,20 Health pr<strong>of</strong>essionals<br />

must not be afraid to enter territory that is uncomfortable<br />

or unknown. <strong>The</strong>re needs to be open, unconditional<br />

positive regard shown towards every<br />

patient for whom we care. Finally, there must be<br />

empathic understanding or ‘sensitive active listening’<br />

not only to the person, but careful listening to<br />

what stories their body can tell us. 21<br />

This is summed up by Connie:<br />

I felt embarrassed and I found it very difficult I<br />

didn’t want other people touching me but when I<br />

got sicker you have to get over that and you can’t<br />

do it for your self so you have to let others do it<br />

for you. But I still don’t want other people making<br />

choices like what I am going to eat. I don’t want<br />

others picking out my food for tea for me.<br />

Limitations <strong>of</strong> this study<br />

<strong>The</strong> most significant and limiting factor was that<br />

most <strong>of</strong> the participants died before their transcripts<br />

could be transcribed and reviewed. This<br />

is a reality in all research where participants have<br />

terminal illness. However their stories are important<br />

and it is the engagement <strong>of</strong> the researcher<br />

with the participant that enables the revelation <strong>of</strong><br />

the essence <strong>of</strong> something. Phenomenology does<br />

not <strong>of</strong>fer the possibility <strong>of</strong> theory that looks at<br />

variables or controls. It does, however, <strong>of</strong>fer the<br />

plausible insights that bring us into contact with<br />

people’s lived experience, in and around us.<br />

Research implications and<br />

recommendations<br />

<strong>The</strong>se findings highlight the need to critically<br />

reflect on practice in a rigorous manner on a daily<br />

basis. <strong>The</strong>y should serve to enlighten health<br />

pr<strong>of</strong>essionals’ internal and external practices and<br />

encourage engagement in self-analysis as truly<br />

caring beings. 22 It is necessary that health pr<strong>of</strong>essionals<br />

actively consider the concept and importance<br />

<strong>of</strong> empowerment. However, more research<br />

needs to be undertaken to understand strategies<br />

related to how empowerment works and the notion<br />

that ‘empowerment is undermined by the<br />

seduction <strong>of</strong> health-discourse so that the patient<br />

ends up wanting what the system wants them<br />

to want’ and who it works for. 10 Further study is<br />

also needed on the effectiveness <strong>of</strong> being instead<br />

<strong>of</strong> doing for our patients.<br />

Conclusion<br />

‘Phenomenology, like poetry, intends to be<br />

silent as it speaks. It wants to be implicit as it<br />

explicates.’ 15 When we enter the world <strong>of</strong> the<br />

patient and actively listen to them, we become<br />

accustomed to their manner <strong>of</strong> speaking, what is<br />

important to them and what individuates them at<br />

this particular point in time. Listening enables us<br />

to get under neath the surface <strong>of</strong> the individual<br />

and their experiences. By using van Manen’s<br />

approach to researching lived experiences, this<br />

study reinforces the importance <strong>of</strong> empowering<br />

those who are terminally ill to remain in control<br />

<strong>of</strong> their day-to-day decisions for as long as possible.<br />

<strong>The</strong> themes reflect key <strong>issue</strong>s that nurses<br />

should reflect on and learn from, so that, when<br />

caring for and working with the terminally ill<br />

patient, this fully engaged being requires different<br />

nursing skills because <strong>of</strong> the unique and<br />

unpredictable psychosocial terms <strong>of</strong> reference<br />

that nurses have to work within.<br />

For each <strong>of</strong> the participants, it was everyday<br />

decisions that concerned them greatly, not the<br />

big, life-changing ones. All <strong>of</strong> the participants<br />

wanted their experiences with a terminal illness<br />

to be their own and to be allowed to die<br />

in their personal way, thus enabling autonomy<br />

and rationality. A positive regard needs to be<br />

revealed before any therapeutic relationship can<br />

ensue. People who are terminally ill are unique<br />

and unpredictable in terms <strong>of</strong> the connection<br />

and dependency within any nursing relationship;<br />

therefore it is imperative that, between the<br />

carer and the cared for, empathic, intuitive, active<br />

listening occurs, resulting in empowerment, feelings<br />

<strong>of</strong> being valued and respected, and enabling<br />

the best possible death.<br />

ABSTRACT<br />

introduction: Practice nurses see patients in both a planned (i.e. scheduled appointment) and an<br />

unplanned (i.e. opportunistic) manner. This study aimed to investigate how <strong>of</strong>ten and why <strong>New</strong> <strong>Zealand</strong><br />

practice nurses see patients prior to the general practitioner and whether they organise their care to support<br />

unplanned, opportunistic activity.<br />

Method: National postal survey from a random sample <strong>of</strong> 500 general practices, requesting a response<br />

from one nurse per practice. Semi-structured telephone interviews with a purposeful sample <strong>of</strong><br />

respondents.<br />

FINDINGS: Responses came from 225 nurses (51% <strong>of</strong> practices confirmed to be eligible). Nearly all (92%)<br />

said their work role was the same as that <strong>of</strong> others in their practice. Only 13% <strong>of</strong> nurses routinely saw<br />

patients prior to the doctor, while 24% would choose to do so it they could, and 65% thought it important.<br />

Positive and negative aspects <strong>of</strong> seeing patients first are presented. Constraints included time, their role<br />

assisting practice workflow and perceptions <strong>of</strong> patient expectations. Few organised their work to create<br />

opportunities for lifestyle interventions.<br />

to see an opportunity<br />

until it had ceased<br />

to be one.’<br />

Conclusion: <strong>The</strong> current working environment <strong>of</strong> practice nurses in <strong>New</strong> <strong>Zealand</strong> does not readily<br />

support them routinely seeing patients before the general practitioner. We suggest this is a lost opportunity<br />

for patient-centred preventive care.<br />

KEYWORDS: Practice nursing roles; opportunistic interventions; work organisation; primary health<br />

care; chronic conditions<br />

Introduction<br />

Practice nurse (PN) work can be considered as<br />

planned and unplanned. Planned work includes<br />

chronic care management clinics and similar ways<br />

<strong>of</strong> organising care to include blocks <strong>of</strong> protected<br />

time to engage with patients in relatively systematic<br />

and prescribed programmes. Unplanned<br />

work includes responding to patient needs as they<br />

present, and proactively taking opportunities<br />

to engage patients on <strong>issue</strong>s which they did not<br />

present. It is this latter, opportunistic work that<br />

interests us in this study.<br />

Identifying and using opportunities effectively<br />

was the principle behind the Brief Opportunistic<br />

Interventions programme developed by author<br />

BD and others at <strong>The</strong> University <strong>of</strong> Auckland. 1<br />

During course feedback <strong>of</strong> this programme, most<br />

nurses stated that the best time to use these<br />

person-centred skills was by seeing the patient<br />

before the general practitioner (GP) (personal<br />

communication B Docherty, 2009). Putting aside<br />

the fact that 23% <strong>of</strong> children and 29% <strong>of</strong> adults<br />

see a PN per year without seeing a GP, 2 these<br />

nurses saw it as problematic that, when patients<br />

saw a GP prior to the PN, the GP <strong>of</strong>ten set the<br />

preventive care agenda prior to any opportunity<br />

for the PN to explore the patient’s agenda. One<br />

logical extension <strong>of</strong> such opportunistic activity<br />

would be for PNs to arrange their work to ensure<br />

that they routinely see every patient, ‘planning’<br />

to create an ‘opportunity’. We therefore sought to<br />

investigate if and when practice nurses can and<br />

do see patients first.<br />

quaLitative research<br />

Methods<br />

A national postal survey was used to collect<br />

quantitative and qualitative data. Semi-structured<br />

interviews were conducted by telephone with a<br />

purposeful sample <strong>of</strong> survey respondents. Ethics<br />

approval was given by <strong>The</strong> University <strong>of</strong> Auckland<br />

Human Participants Ethics Committee (Reference<br />

number 206/381). In <strong>New</strong> <strong>Zealand</strong>, university<br />

ethics committees can approve studies <strong>of</strong> health<br />

care pr<strong>of</strong>essionals, while the Ministry <strong>of</strong> Health<br />

committees can approve studies with patients.<br />

Participants<br />

A contact list for general practices in <strong>New</strong> <strong>Zealand</strong><br />

was constructed from data held by the Department<br />

<strong>of</strong> <strong>General</strong> Practice and Primary Health<br />

Care and the Immunisation Advisory Service,<br />

both at <strong>The</strong> University <strong>of</strong> Auckland. <strong>The</strong> list contained<br />

1915 organisations presumed to be general<br />

medical practices, from which 500 were randomly<br />

selected using the rand() function in Excel, and<br />

sent one copy <strong>of</strong> the survey questionnaire. We<br />

requested one response from a practice nurse per<br />

practice. <strong>The</strong> sample size was chosen on the basis<br />

<strong>of</strong> available resources, anticipating a response rate<br />

<strong>of</strong> 60%, and was considered more than adequate<br />

for the simple descriptive statistics planned.<br />

Data collection: questionnaire<br />

<strong>The</strong> content <strong>of</strong> the questionnaire was developed<br />

initially based on feedback from nurse training<br />

courses run by author BD and from anecdotes<br />

and experience in primary care by author TK.<br />

Drafts were iteratively tested for content and<br />

face validity with a panel <strong>of</strong> 36 primary health<br />

care nurses.<br />

<strong>The</strong> final questionnaire, which can be found in Appendix<br />

1 in the web version <strong>of</strong> the paper, consisted<br />

<strong>of</strong> 20 closed questions and 11 open questions.<br />

<strong>The</strong> closed questions asked about practice nurse<br />

demographics, pr<strong>of</strong>essional qualifications, and<br />

preferences and practices. <strong>The</strong> open questions gave<br />

practice nurses the opportunity to expand on their<br />

answers and give examples. <strong>The</strong> questionnaires<br />

were tagged with a temporary identification code<br />

to track non-responders. <strong>The</strong> questionnaires were<br />

sent in December 2006, and a follow-up request<br />

was sent to initial non-responders in January 2007.<br />

WHAT GAP THIS FILLS<br />

What we already know: In <strong>New</strong> <strong>Zealand</strong> in 2006/7, 41% <strong>of</strong> adults saw a<br />

practice nurse in the previous 12 months and 85% attended a general practice.<br />

For practice nurses, this is largely for clinical care and planned, structured care.<br />

What this study adds: A minority <strong>of</strong> practice nurses routinely see patients<br />

before they see the doctor, or organise their work to routinely support<br />

unplanned, ‘opportunistic’ person-centred care.<br />

Name and address lists were stored independently<br />

<strong>of</strong> the questionnaires. Respondents were assured<br />

that they would not be identified in any report.<br />

Data collection: interviews<br />

Respondents to the postal questionnaire were<br />

also asked to provide their name and contact<br />

details if they were interested to take part in a<br />

follow-up telephone interview. From this group<br />

we purposefully selected 20 practice nurses to<br />

cover a range <strong>of</strong> age, ethnicity, employment and<br />

geography. <strong>The</strong> guide questions for the interview<br />

were developed following a preliminary analysis<br />

<strong>of</strong> the survey responses, and can be found<br />

in Appendix 2 in the web version <strong>of</strong> the paper.<br />

Questions were intended primarily to confirm<br />

our interpretation <strong>of</strong> the quantitative data. Written<br />

consent was obtained prior to each interview.<br />

<strong>The</strong> interviews lasted from 20 to 35 minutes,<br />

were digitally recorded and transcribed. We <strong>of</strong>fered<br />

interviewees the opportunity to view their<br />

transcript and to receive a copy <strong>of</strong> our report.<br />

Data analysis<br />

Quantitative data were entered and checked in<br />

Excel. Qualitative data from the questionnaires,<br />

together with the interviews, were entered into<br />

NVivo v7.0 for analysis. A general inductive approach<br />

was used for a thematic analysis 3 that was<br />

initially undertaken independently by authors<br />

TK, NS and BD, then confirmed and enriched<br />

by consensus.<br />

practice had ceased operating, or the organisation<br />

was not a general practice; and 32 practices had<br />

no practice nurses. <strong>The</strong>re were 225 responses<br />

giving a response rate <strong>of</strong> 225/444 (51%). <strong>The</strong>se<br />

225 individual practice nurses represented 225<br />

practices, with a total <strong>of</strong> 843 practice nurses<br />

and 802 GPs. Ninety-two percent said that their<br />

job was the same as that <strong>of</strong> the other nurses in<br />

the practice, or they were the only nurse in the<br />

practice. Descriptive statistics for respondents are<br />

in Table 1.<br />

Training in lifestyle behaviour change had been<br />

undertaken by 143 practice nurses (64%). Of<br />

these, most indicated condition-specific training<br />

such as for smoking cessation (46), diabetes (44),<br />

asthma (19) or exercise, weight management and<br />

nutrition (29), while only 38 described generic<br />

courses such as Brief Opportunistic Interventions<br />

training. 2<br />

<strong>The</strong> great majority <strong>of</strong> the nurses saw the positives<br />

and negatives <strong>of</strong> seeing patients first in purely<br />

transactional, workflow terms. <strong>The</strong>y could take<br />

very different attitudes to what appeared to be<br />

the same activities:<br />

Chance to get to know patients better, catch up<br />

with recalls, bloods etc. sometimes patients tell<br />

PN things they won’t tell GPs. Good interaction<br />

Responses are summarised in Table 2, which<br />

reflects responses from all the free text questions<br />

in the questionnaire. As in the quotations above,<br />

some <strong>of</strong> the comments contradict each other,<br />

presumably reflecting a variety <strong>of</strong> PN attitudes<br />

and work situations.<br />

When asked when it would be beneficial for<br />

PNs to see the patient first, 147 PNs replied,<br />

most giving several examples. <strong>The</strong> great majority<br />

<strong>of</strong> examples were activities relating to practice<br />

workflow—emergencies, patients arriving<br />

without an appointment or when the GP was<br />

fully booked or running behind time. Thirty<br />

PNs nominated activities that are shaped by<br />

a specific schedule <strong>of</strong> tasks—such as ‘diabetes<br />

checks’, ‘wellness checks’, ‘antenatal visits’, ‘new<br />

patient visits’—that, nevertheless could poten-<br />

tially be used to discuss lifestyle changes in a<br />

patient-centred manner. Seven PNs specifically<br />

noted the opportunity to engage in discussions<br />

and advice around patient lifestyle changes.<br />

Several specifically noted an advantage <strong>of</strong> their<br />

female gender:<br />

Most women are comfortable talking to another<br />

woman about menstrual, sexual, menopause problems.<br />

Some patients feel like they don’t want to<br />

waste doctor’s time so talk to nurse. (#84)<br />

Only two specifically noted their role dealing<br />

with mental health <strong>issue</strong>s:<br />

Depressed, embarrassed elderly woman needing<br />

reassurance. (#332)<br />

Interviews<br />

One hundred and thirty-two nurses indicated<br />

that they were willing to be interviewed, from<br />

which we selected 26. Of these, seven routinely<br />

saw all patients first and nine would choose to<br />

see all patients first if they could. Summary<br />

descriptions <strong>of</strong> the nurses interviewed are in<br />

Table 3.<br />

Perceptions <strong>of</strong> ‘usefulness’ were the principal<br />

drivers <strong>of</strong> whether practice nurses routinely saw<br />

patients prior to the GP.<br />

I can’t really see… practice nurses doing the consultations<br />

first before seeing [the doctor]. All I can do<br />

sometimes is… just take the occupation, height and<br />

weight, when they’re doing some… CVD assessment.<br />

But most <strong>of</strong> the time, there’s not much to do<br />

with them. (#452)<br />

Usefulness was primarily seen as an administrative<br />

role that would contribute to the workflow<br />

<strong>of</strong> the doctors…<br />

It saves the doctors time because we can do blood<br />

pressures weights and take temperatures, get a<br />

basic history before they see them, so they just<br />

need to quickly scan the notes and they’re already<br />

there. (#45)<br />

…and their workflow came secondary to the<br />

doctors’.<br />

themes from free text in questionnaires<br />

Positives<br />

• Time efficient mostly stated as for GPs, practice and patients, occasionally for PNs<br />

• Continuity <strong>of</strong> care with PN<br />

• Reduction <strong>of</strong> GP workload and stress, all patients do not need to see GP<br />

• Screening, opportunistic education<br />

• Assists GP with essential history prior to GP consultation<br />

• PNs gain experience and educational opportunities<br />

• Increases PN confidence in clinical skills<br />

• Strengthens PN–patient relationships<br />

• Strengthens GP–PN relationship, GP recognises PN skills<br />

• Better care and outcomes for patients<br />

• Autonomy to triage and initiate first aid for emergency patients<br />

• Opportunity to use learned skills, e.g. brief interventions<br />

• Strengthens nursing holistic approach<br />

• More input from PN allows patients to utilise PN more<br />

• Patients more likely to talk to PNs and to be more ‘honest’<br />

• Assist in diagnosis and treatment <strong>of</strong> acute cases<br />

• Perception that PN is less busy than GP<br />

• Improves access for patients when PN service free<br />

• Establishes PN role with patients as independent health pr<strong>of</strong>essional<br />

Negatives<br />

• Patient has right to choose provider (autonomy)<br />

• Patient may want confidentiality or privacy<br />

• Patients may expect to see GP not PN<br />

• Total patient time in practice longer<br />

• Relationship is with the GP not the PN<br />

• Alters GP–patient relationship, PN undermining GP position<br />

• <strong>New</strong> way <strong>of</strong> working for patients, patient resistance<br />

• GP may not want patient to see the PN first<br />

• Patients seen twice and history-taking repeated<br />

• Time constraints, time waster<br />

• PN workload increased, PN already too busy<br />

• No financial reward for PN<br />

• Not cost-effective for practice or patient<br />

• Would reduce consultation time with PN and/or GP<br />

• Increase work hours and paperwork for both PNs and GPs<br />

• Not interesting enough, boring<br />

• PN training inadequate<br />

quaLitative research<br />

A lot <strong>of</strong> wounds have to be seen by the GP only for<br />

claiming purposes and it’s a waste <strong>of</strong> time because<br />

you need to have the patient sitting around, you’re<br />

waiting for the GP to come in… (#457)<br />

<strong>The</strong> nurses might be ‘useful’ to patients by being<br />

time efficient with administrative <strong>issue</strong>s.<br />

…You’ll be doing some treatment type care for them<br />

and at the same time you’ll take note <strong>of</strong> their other<br />

health <strong>issue</strong>s like recalls and things like that that<br />

they might be due for… (#490)<br />

Nevertheless, there was considerable variation<br />

between nurses in what they saw as useful. Many<br />

saw themselves as never having anything useful<br />

to contribute by seeing patients first, while others<br />

each nominated a small number <strong>of</strong> specific<br />

medically-defined conditions—such as diabetes,<br />

asthma and sexual health—in which they felt<br />

sufficiently skilled and confident to see patients<br />

first. However, the skill list nominated by each<br />

nurse seemed very partial, implying that the<br />

medical conditions <strong>of</strong> the majority <strong>of</strong> patients<br />

could not be ‘matched’ by any one nurse.<br />

<strong>The</strong> nurses who preferred to see all patients<br />

first, however, saw their skills in more generic<br />

terms that were independent <strong>of</strong> specific medical<br />

conditions. <strong>The</strong>se nurses—a minority in both the<br />

questionnaires and interviews—spoke <strong>of</strong> their<br />

role forming and maintaining relationships with<br />

patients, and <strong>of</strong> sensing or seeking opportunities<br />

while performing administrative tasks.<br />

That’s an advantage <strong>of</strong> seeing the patients in the<br />

first place, by doing the weight and by doing the<br />

those are all the things that we do… we use every<br />

Most nurses gave a sense <strong>of</strong> being pressured and<br />

controlled by time. Nevertheless, the few nurses<br />

who routinely saw patients first gave a sense <strong>of</strong><br />

multi-tasking and using time, suggesting that<br />

time was the very thing they could <strong>of</strong>fer the<br />

patient that the doctor could not.<br />

We’re able to discuss those <strong>issue</strong>s because we’ve got<br />

more time than the doctors have. (#45)<br />

Frustrations with time pressure seemed more<br />

directed at patients and receptionists than doctors<br />

or the wider health system, and appeared to be<br />

accepted as inevitable.<br />

Nurse perceptions and presumptions about<br />

patient expectations also formed a powerful influence<br />

on whether they saw patients first (or at all).<br />

Nurses mostly took it for granted that patients<br />

<strong>of</strong>ten came specifically to see the doctor—and, by<br />

implication, not the nurse:<br />

I also don’t know how patients would react to seeing<br />

a nurse first if they’ve chosen to make a doctor’s<br />

appointment. (#397)<br />

…that patients had every right to do so:<br />

I feel that we’re taking away patients’ rights to a<br />

certain extent if we chose to do that role automatically.<br />

(#490)<br />

…that patients were entitled to privacy and confidentiality<br />

that might extend to the doctor but not<br />

the nurse:<br />

…<strong>The</strong>y want to wait until the doctor if they feel<br />

it’s something they don’t want to discuss, if they<br />

don’t want me to know they can leave it until<br />

they do see him. (#54)<br />

…and that nurses, doctors and patients probably<br />

share an implicit sense <strong>of</strong> when it was<br />

‘useful’ for the nurse to see the patient first.<br />

However, this may simply be a matter <strong>of</strong> patients,<br />

and nurses, becoming familiar with<br />

a new arrangement.<br />

I have only one patient who has not wanted to see<br />

the nurse, out <strong>of</strong> all the thousands that we see<br />

there’s probably one guy who would rather just see<br />

the doctor. (#45)<br />

Discussion<br />

Nurses undertook work they considered ‘useful’,<br />

that they considered to be acceptable to patients,<br />

and within limits imposed by time pressure. As<br />

such, only 13% <strong>of</strong> practice nurses routinely saw<br />

all patients before they saw a GP, while 24%<br />

thought it desirable and 65% thought it important.<br />

PNs viewed seeing patients first largely<br />

as an administrative role to assist practice and<br />

GP workflow. A minority took a different view,<br />

seeing patients first because they saw themselves<br />

as <strong>of</strong>fering skills and a relationship that doctors<br />

did not <strong>of</strong>fer. While most nurses acknowledged<br />

that they could become involved in opportunistic<br />

discussions while engaged in clinical care, there<br />

was no sense <strong>of</strong> routinely or proactively creating<br />

such opportunities.<br />

A strength <strong>of</strong> this study is that we surveyed the<br />

<strong>entire</strong> country. <strong>The</strong> fact that 92% <strong>of</strong> respondents<br />

said their job is the same as that <strong>of</strong> the other<br />

nurses in the practice supports our strategy <strong>of</strong><br />

sampling one nurse per practice, as it suggests<br />

that the respondents may be similar to the<br />

nurses not sampled in the same practice. Nevertheless,<br />

our response rate <strong>of</strong> just over half calls<br />

for caution interpreting the results. We have<br />

no data to describe the practices from which we<br />

received no response.<br />

<strong>The</strong> nearest comparative data to our survey is<br />

from a recent evaluation <strong>of</strong> nursing developments<br />

in primary health, which included a national<br />

survey <strong>of</strong> PNs. 4 <strong>The</strong> response rate to their survey<br />

was only 34% and included 384 practice nurses.<br />

This evaluation made it clear that PNs around the<br />

country are increasingly taking up the (planned)<br />

activities involved in structure projects, 5 as was<br />

hoped and expected following <strong>The</strong> <strong>New</strong> <strong>Zealand</strong><br />

Health Strategy 6 and <strong>The</strong> Primary Health Care<br />

Strategy. 7 <strong>The</strong> increase in structured care by PNs<br />

is reflected in the current study, but it also seems<br />

clear from our work that the dedicated time devoted<br />

to structured care, reflected in the number<br />

<strong>of</strong> nurses with their own appointment list, is one<br />

<strong>of</strong> the barriers to PNs taking up unplanned, opportunistic<br />

activities.<br />

Given the perennial problem <strong>of</strong> patients spending<br />

‘too long’ in waiting rooms, we suggest<br />

that PNs routinely seeing patients first is an<br />

opportunity that is largely missed. Seeing<br />

patients first also represents an opportunity<br />

to pr<strong>of</strong>ile PNs, especially given findings that<br />

PNs are frequently anonymous and ‘invisible’<br />

to patients, and that patients can enormously<br />

value a personal pr<strong>of</strong>essional relationship with<br />

a PN. 8 In pr<strong>of</strong>iling PNs, seeing patients first<br />

would help break down one <strong>of</strong> the very barriers<br />

mentioned by our respondents, when they<br />

considered that some patients expect and prefer<br />

to see the doctor.<br />

A seminal paper that shaped the theory <strong>of</strong><br />

general medical practice proposed ‘opportunistic<br />

health promotion’ as one <strong>of</strong> four key dimensions<br />

<strong>of</strong> the ‘exceptional potential’ <strong>of</strong> the GP consultation.<br />

9 We suggest that the same opportunity can<br />

be taken or created within PN care, recognising<br />

that this needs appropriate training and working<br />

conditions that formally acknowledge and support<br />

this role.<br />

ABSTRACT<br />

Introduction: <strong>The</strong>re is a need for educated primary health nurses to develop their practice, educational<br />

and career pathways in response to opportunities emerging from the Primary Health Care Strategy<br />

(PHCS). This study aimed to explore the opportunities and constraints encountered by practice nurses<br />

when participating in post-registration education.<br />

Methods: This study used exploratory qualitative design, incorporating focus group interviews with 16<br />

practice nurses employed by Pegasus Health, Christchurch. Qualitative thematic analysis used a general<br />

inductive approach.<br />

Findings: Seven key themes emerged, including motivation to learn, enablers for learning and challenges<br />

to accessing education. Practice nurses also described their changing roles with clients and their<br />

vision for practice nursing in the future.<br />

Conclusion: This study considered accessibility <strong>of</strong> post-registration education for practice nurses<br />

and the extent to which they are embracing these opportunities in order to meet their practice needs.<br />

<strong>The</strong> PHCS states that primary health care nursing is crucial to its implementation. Successful expansion<br />

<strong>of</strong> primary health care nursing roles rests on the development <strong>of</strong> educational qualifications and skills,<br />

as well as career frameworks. It is envisaged that, with strong leadership and research skills resulting<br />

from pr<strong>of</strong>essional development, practice nurses will be more able to reduce health inequalities. Study<br />

findings indicate that practice nurses are rising to the challenge <strong>of</strong> expanding their roles and engaging in<br />

post-registration education. <strong>The</strong>y are more likely to pursue this if constraints are minimised and support<br />

increased. Currently practice nurses make significant contributions to primary health care and have the<br />

potential for an even greater contribution in the future.<br />

Introduction<br />

In 2001 the <strong>New</strong> <strong>Zealand</strong> (NZ) Primary Health<br />

Care Strategy (PHCS) was launched. 1 <strong>The</strong> strategy<br />

provided a framework for the health sector<br />

with a focus on population health and addressing<br />

health inequalities <strong>of</strong>fering opportunities<br />

for nurses in primary health care to develop<br />

their practice, educational and career pathways.<br />

<strong>General</strong> practitioners have been employers <strong>of</strong><br />

practice nurses for many years. Working within<br />

a business model has been challenging to nurses<br />

seeking to establish a greater degree <strong>of</strong> autonomy<br />

<strong>of</strong> practice. 2 <strong>The</strong> Ministry <strong>of</strong> Health calls<br />

for governance and leadership opportunities for<br />

practice nurses. Nursing leadership in primary<br />

health care in NZ has had a history <strong>of</strong> being<br />

‘fragmented and devolved to individual primary<br />

health care providers’. 3 However, this situation<br />

has changed over time with District Health<br />

Boards (DHBs) and Primary Health Organisations<br />

(PHOs) recognising the need for nursing<br />

leadership at all levels. <strong>The</strong> Ministry <strong>of</strong> Health<br />

document Investing in Health: Whakatohutia<br />

te Oranga Tangata outlined a comprehensive<br />

framework in which nurses can have a key role<br />

in implementing the Primary Health Care Strat-<br />

egy. 4 <strong>The</strong> strategy has highlighted opportunities<br />

for nurses to gain advanced nursing practice<br />

qualifications and to develop their roles. Nurses<br />

constitute the largest pr<strong>of</strong>essional group working<br />

in primary health care, yet their potential<br />

roles within the workforce remain unrealised. 5<br />

According to Jones, the Chief Nursing Advisor<br />

to the Ministry <strong>of</strong> Health, the ability <strong>of</strong><br />

practice nurses to communicate with people,<br />

work within the context <strong>of</strong> NZ families and<br />

understand the impact <strong>of</strong> the environment on<br />

their health are highly developed skills. 6 Jones<br />

questions whether practice nurses are equipped<br />

to practise more independently if a family or<br />

individual chose them as their primary health<br />

care pr<strong>of</strong>essional.<br />

<strong>The</strong>re is a critical need for a skilled and educated<br />

workforce to meet the challenging needs<br />

within primary health care. 4 <strong>The</strong> expectations<br />

for primary nursing to develop new roles in<br />

primary health care and to become increasingly<br />

autonomous require access to pr<strong>of</strong>essional<br />

development. Many practice nurses working in<br />

general practices may not wish to become nurse<br />

practitioners nor obtain a clinical postgraduate<br />

qualification, but want to gain the knowledge<br />

required for them to work in their unique role in<br />

the primary health care workforce. 7 This may be<br />

interdisciplinary education with a general practitioner<br />

or a short course with other practice nurse<br />

colleagues. However, Minto sees the future <strong>of</strong><br />

practice nursing as being more mobile, whereby<br />

nurses will visit patients in their homes, be more<br />

educated (most will have postgraduate education)<br />

and better paid. 2<br />

Several constraints to practice nurses’ ongoing<br />

pr<strong>of</strong>essional development are cited in the<br />

literature. First is the need for funding for<br />

pr<strong>of</strong>essional development in primary health care.<br />

Practice nurses have only been able to access<br />

funding from established streams, such as the<br />

Clinical Training Agency (CTA) since 2007. 8<br />

According to Pullon, ‘Primary Health Organisations<br />

have largely not considered practice nurse<br />

pr<strong>of</strong>essional development as their responsibility’.<br />

7 <strong>The</strong> funding shift from DHBs has enabled<br />

them to purchase postgraduate education for both<br />

primary health care nurses and hospital nurses.<br />

Some general practice employers have supported<br />

WHAT GAP THIS FILLS<br />

What we already know: Opportunities for nurses to extend their population<br />

health focus and an increased range <strong>of</strong> services in primary health care<br />

have been clearly identified in the Primary Health Care Strategy. <strong>The</strong>re is<br />

a need for well-educated primary health nurses with developing practice,<br />

educational and career pathways.<br />

What this study adds: This research identifies the constraints and opportunities<br />

experienced by practice nurses in furthering post-registration<br />

education and developing leadership roles in primary health care.<br />

practice nurse pr<strong>of</strong>essional development with<br />

contracts <strong>of</strong> up to five days a year to study; more<br />

<strong>of</strong>ten this study is undertaken in their own<br />

time and at their own cost. A further constraint<br />

in practice nurses obtaining study leave is that<br />

practice locums—<strong>of</strong>ten needed to cover the<br />

positions—can be difficult to find. <strong>The</strong> provision<br />

<strong>of</strong> short courses to acquire clinical skills for practice<br />

nurses may not lead to a qualification, as the<br />

courses may not be linked to the <strong>New</strong> <strong>Zealand</strong><br />

Qualifications Authority framework. 5 Also, the<br />

continual updating <strong>of</strong> specific practising certificates,<br />

such as vaccinators or smear takers, may<br />

lead to practice nurses focussing on these to the<br />

detriment <strong>of</strong> undertaking further pr<strong>of</strong>essional<br />

development.<br />

A growing body <strong>of</strong> literature explores practice<br />

nursing roles in Australia, NZ and the United<br />

Kingdom (UK). 9,10,11,12 Parker et al. 12 and Halcombet<br />

al. 10 note that significant developments have<br />

been made in NZ and the UK to advance primary<br />

health care nursing education and career pathways.<br />

However, in Australia there is no policy<br />

at a national level to prepare nurses for primary<br />

health care, nor a framework for education or<br />

career pathways. In a 2007 Australian survey<br />

the educational needs <strong>of</strong> practice nurses reflected<br />

their current roles, but did not address developing<br />

roles. 13 <strong>The</strong>re has been a call for the development<br />

<strong>of</strong> education and training programmes,<br />

supporting the need for a quality education and<br />

career framework for practice and other nurses in<br />

primary health care. 12,14 Since 2001, the potential<br />

for enhanced roles <strong>of</strong> NZ practice nurses has been<br />

recognised. 12 This includes responding to community<br />

need, developing leadership and models <strong>of</strong><br />

practice, holding governance positions in PHOs,<br />

and developing a national career pathway for<br />

primary health care nurses.<br />

Methods<br />

An exploratory qualitative research design was<br />

implemented, using focus group interviews. Focus<br />

group interviews were selected for this study<br />

as their interactive nature allows the participants<br />

in a group to comment, explain, disagree,<br />

and share attitudes and experiences, providing<br />

rich perspective in the context in which events<br />

occur. 15,16 Ethical approval was obtained from<br />

Christchurch Polytechnic Institute <strong>of</strong> Technology<br />

and the <strong>New</strong> <strong>Zealand</strong> Health and Disability Ethics<br />

Committee in June 2008.<br />

<strong>The</strong> sample group was practice nurses employed<br />

by general practitioners <strong>of</strong> Pegasus Health Limit-<br />

Kreuger’s tape and note-based approach 18 was<br />

employed for analysis in conjunction with a fourstage<br />

approach guided by Boyatzis. 19<br />

Researchers first listened to the audiotapes then<br />

entered a process <strong>of</strong> reading, listening and summarising<br />

the raw data to identify multiple views<br />

and perceptions <strong>of</strong> participants and to recognise<br />

codable moments. 19 Codes were compared and<br />

examined for their potential to inadvertently reflect<br />

the researchers’ personal values and, finally,<br />

interpreted to contribute to the development <strong>of</strong><br />

knowledge. Finally, key information was identified<br />

and presented in seven themes.<br />

Methodological rigour was achieved through<br />

trustworthiness and authenticity criteria adapted<br />

from the work <strong>of</strong> Lincoln and Guba. 20 <strong>The</strong><br />

research plan was carefully documented, using<br />

In all focus groups, practice nurses identified several challenges to<br />

accessing education courses. <strong>The</strong>se included their employer<br />

supporting only ‘in-house education’, lack <strong>of</strong> assistance to get time<br />

<strong>of</strong>f work if the courses were held during the day, and finding<br />

appropriate courses relevant to practice nursing<br />

ed who had engaged in post-registration education<br />

at graduate (n=10) and postgraduate levels (n=6).<br />

Graduate education included formal learning at<br />

700 level and postgraduate, formal education at<br />

800 level. Practice nurses were selected by a convenience<br />

sampling approach; that is a sample <strong>of</strong><br />

the population that was readily available. Practice<br />

nurses were invited by letter to participate in the<br />

focus groups. To be suitable for inclusion, all practice<br />

nurses were working full-time, currently or<br />

previously engaged in post-registration education<br />

and employed by Pegasus Health (320). 17 Sixteen<br />

participants attended the focus group interviews.<br />

<strong>The</strong> moderator encouraged participant discussion<br />

but avoided leading the group to reinforce existing<br />

assumptions. In addition to the audiotaped<br />

data, notes were taken by the moderator during<br />

the discussions and participants were given opportunity<br />

to clarify their comments and ideas.<br />

the same data collection and analysis techniques<br />

utilised for all three focus groups. Preliminary<br />

results were mailed to participants inviting them<br />

to participate in the analysis by verifying or adding<br />

to the findings.<br />

Findings<br />

Specific demographic information <strong>of</strong> the nurses in<br />

the study is not provided due to ethical considerations<br />

<strong>of</strong> anonymity. However, the 16 participants<br />

were all women, whose ages ranged from 25 to 61<br />

years. Practice nursing experience ranged from<br />

three to five years (for three recently graduated<br />

nurses) and five to 25 years for the other 13 registered<br />

nurses. <strong>The</strong> majority <strong>of</strong> participants identified<br />

as European/Pakeha <strong>New</strong> <strong>Zealand</strong>er.<br />

Seven key themes emerged.<br />

144 VOLUME 2 • NUMBER 2 • JUNE 2010 J OURNAL OF PRIMARY HEALTH CARE


ORIGINAL SCIENTIFIC PAPErS<br />

quaLitative research<br />

1. Motivation to learn<br />

In each focus group, all practice nurses talked<br />

about wanting to be better—‘to improve myself<br />

all the time’ to help people and feel efficient.<br />

<strong>The</strong>y wanted to be knowledgeable, using clinical,<br />

evidence-based knowledge to ‘deliver better<br />

practice’. <strong>The</strong> majority <strong>of</strong> participants talked<br />

about the personal satisfaction they gained from<br />

learning. <strong>The</strong>y recognised that ‘knowledge is<br />

power’, which enabled them to improve their<br />

nursing skills to benefit clients while providing<br />

the increased intellectual stimulation that accompanies<br />

learning. Eight participants mentioned the<br />

self-confidence gained by participating in courses.<br />

Seven practice nurses spoke <strong>of</strong> the enjoyment<br />

<strong>of</strong> networking and studying together, especially<br />

for solo practitioners. Developing clinical skills<br />

was important for 14 participants, engaging in<br />

learning that was particularly useful for practice.<br />

Several courses were mentioned: cervical smear<br />

taking, Appetite for Life (healthy eating programme),<br />

preceptorship <strong>of</strong> student nurses, clinical<br />

supervision, along with more formal education<br />

such as the Bachelor <strong>of</strong> Nursing transition programme<br />

and the Graduate Certificate in Nursing<br />

Practice. <strong>The</strong> practice nurses described a strong<br />

commitment to learning—‘I could be addicted<br />

to learning, if it didn’t cost so much and I didn’t<br />

have to complete assignments!’<br />

2. Enablers for learning<br />

Nine practice nurses described being in an atmosphere<br />

that helped motivate them to learn—in<br />

‘like minded groups’. <strong>The</strong>re was agreement in<br />

all focus groups that funding for nurse-related<br />

education that became available in 2007 via the<br />

CTA was ‘a huge barrier to break’ in increasing<br />

the affordability <strong>of</strong> formal study. This meant that<br />

practice nurses could be funded for the full cost<br />

<strong>of</strong> course fees, relief in practice and travel and<br />

accommodation expenses to attend courses, if an<br />

equivalent course was not available locally.<br />

In each focus group all practice nurses spoke<br />

about a difference between practice nurse education<br />

at a clinical level and the courses available at<br />

Christchurch Polytechnic Institute <strong>of</strong> Technology<br />

(CPIT) or university education. ‘It [postgraduate<br />

study] extends you as a registered nurse in the<br />

world’. CPIT graduate courses were described as<br />

being ‘so practical’ and ‘relating to practice nursing<br />

well’. <strong>The</strong> educational credits scheme, where<br />

practice nurses gain credits to access courses as<br />

payment for preceptoring nursing students was<br />

considered very helpful by most participants.<br />

Opportunities for education through Pegasus<br />

Health were mentioned by all focus groups. Full<br />

financial support to attend courses such as the<br />

Child and Adult Health Assessment <strong>of</strong>fered<br />

by CPIT, was a ‘turning point’ in their engagement<br />

in education. <strong>The</strong> funding <strong>of</strong> courses was<br />

described as a ‘massive reason why I have looked<br />

twice’ at child health assessment courses, motivational<br />

learning and diabetes courses. Participants<br />

mentioned the rewards <strong>of</strong>fered by Pegasus Health<br />

to attend group education sessions as enabling<br />

them to engage in study.<br />

3. Challenges to accessing education<br />

In all focus groups, practice nurses identified<br />

several challenges to accessing education courses.<br />

<strong>The</strong>se included their employer supporting only<br />

‘in-house education’, lack <strong>of</strong> assistance to get time<br />

<strong>of</strong>f work if the courses were held during the day,<br />

and finding appropriate courses relevant to practice<br />

nursing. Shortages <strong>of</strong> relieving nurses were<br />

mentioned by most participants as a challenge and<br />

weekend courses made it difficult to maintain the<br />

balance <strong>of</strong> family and work commitments.<br />

Six practice nurses mentioned the ‘steep learning<br />

curve’ <strong>of</strong> getting into academic writing, using a<br />

computer and managing the workload <strong>of</strong> master’s<br />

education. Two practice nurses spoke <strong>of</strong> ‘taking<br />

a sabbatical’ to engage in master’s study. <strong>The</strong>se<br />

challenges did not appear to demotivate the practice<br />

nurses to strive for learning. One mentioned<br />

that ‘being a solo practitioner’ prompted her<br />

personal learning and others were not deterred in<br />

finding appropriate courses, planning and budgeting<br />

for study.<br />

4. Negotiating with the employer<br />

Negotiating study leave with their employer was<br />

mentioned in all three focus groups. This included<br />

coming to agreement that the practice nurses<br />

engage in a course, the funding <strong>of</strong> the course and<br />

being uncomfortable asking for leave when they<br />

VOLUME 2 • NUMBER 2 • JUNE 2010 J OURNAL OF PRIMARY HEALTH CARE 145


ORIGINAL SCIENTIFIC PAPERS<br />

quaLitative research<br />

had ‘already done a course that year’. Seven practice<br />

nurses spoke <strong>of</strong> creating some ‘buy in’ from<br />

the employer, so they needed to find courses<br />

which would benefit and were relevant to the<br />

practice. Some practices are run by managers and<br />

two practice nurses had cervical screening funded<br />

when they signed a bond to stay in the practice<br />

for a year following completion. Two practice<br />

nurses spoke <strong>of</strong> being so motivated to learn skills<br />

such as cervical screening that they paid for some<br />

<strong>of</strong> the course fees, with their employer funding<br />

the remainder.<br />

5. Changing clients<br />

All practice nurses described the changing client<br />

as a motivator for them to study. <strong>The</strong>y described<br />

clients in the twenty-first century as ‘well read<br />

and better informed’ and felt they ‘owed it to<br />

their clients’ to provide quality and up-to-date<br />

information. In each focus group practice nurses<br />

stated that clients may not be aware <strong>of</strong> the<br />

potential <strong>of</strong> practice nurses when they come into<br />

the practice and they would like to develop and<br />

market their skills to their client base.<br />

6. <strong>The</strong> changing role <strong>of</strong> the practice nurse<br />

<strong>The</strong>re was consensus that the practice nurse role<br />

had changed so much over the past eight years,<br />

emphasising new opportunities for practice<br />

nurses <strong>of</strong>fered by the PHCS. Changes included<br />

people being ‘put back into the community, with<br />

much more acute care required’ and that practice<br />

nurses are ‘expected to do much more’. This<br />

has motivated nurses to ‘catch up’ (researching<br />

current knowledge while in the workplace) and<br />

‘get involved in CPIT learning’. According to<br />

four participants, the role <strong>of</strong> the practice nurse<br />

has developed in the last 20 years, from being<br />

‘handmaiden’ to becoming ‘colleagues <strong>of</strong> the doctors’.<br />

<strong>The</strong>re was pride in their comments; practice<br />

nurses described themselves as ‘very sharp and go<br />

ahead’. In all focus groups participants spoke <strong>of</strong><br />

special projects that they are involved with such<br />

as ‘Care Plus’, a project for people with chronic<br />

illness and high health needs and ‘Services to<br />

Improve Access’ where the practice nurse and<br />

general practitioner can access funding to assist<br />

clients and families to access health care. <strong>The</strong>se<br />

projects were mentioned in terms <strong>of</strong> practice<br />

nurses becoming more innovative in their approach<br />

to reducing social inequalities. <strong>The</strong>re<br />

was also a change in emphasis in education for<br />

practice nurses, with the need to maintain their<br />

practising certificates through the development <strong>of</strong><br />

pr<strong>of</strong>essional portfolios. Some anticipated the day<br />

when practice nurses might be directly funded in<br />

their workplaces.<br />

7. Vision as a practice nurse/<br />

vision for practice nursing<br />

‘We are so valuable!’ one practice nurse stated,<br />

and there was consensus that practice nurses are<br />

increasingly working independently, alongside<br />

GPs. Ten participants spoke <strong>of</strong> conducting more<br />

nurse consultations, where the ‘nurse owns the<br />

consult’. This growing autonomy was described<br />

as more satisfying and rewarding for practice<br />

nurses—‘we have quite a bit <strong>of</strong> autonomy, depending<br />

on our employer’.<br />

‘Moving up a level’ was also described in terms<br />

<strong>of</strong> engaging in special projects, where the practice<br />

nurses felt they were maximising their skills.<br />

This included mentoring new graduates, running<br />

nurse-led clinics and leading consultations.<br />

Ten practice nurses spoke <strong>of</strong> wanting to lift their<br />

image <strong>of</strong> themselves, to be more confident in<br />

what they can <strong>of</strong>fer and acknowledgement <strong>of</strong> the<br />

income they bring into the practice. <strong>The</strong> manner<br />

in which practice nurses worked was discussed<br />

throughout the focus groups. Ten participants<br />

envisaged the development <strong>of</strong> the primary<br />

health care team, where comprehensive care was<br />

provided. One example included intersectoral collaboration,<br />

with a multidisciplinary health team<br />

in the same building with services such as Work<br />

and Income <strong>New</strong> <strong>Zealand</strong>.<br />

Discussion<br />

<strong>The</strong> 2001 PHCS signalled an increased emphasis<br />

on population health, community involvement,<br />

health promotion and illness prevention, with<br />

primary health care nurses being vital to the<br />

implementation <strong>of</strong> the strategy. 1 Practice nurses<br />

have responded to the challenge with considerable<br />

role development and have been key members<br />

<strong>of</strong> the primary health care team in addressing<br />

inequality <strong>of</strong> health care and working with<br />

people with chronic disease. 21 According to Rolls,<br />

well-educated nurses can find solutions to health<br />

problems more comprehensively, promptly and efficiently<br />

than others, thus clients are <strong>of</strong>fered the<br />

best possible nursing care. 22 Sibbald et al. found<br />

in a systematic review <strong>of</strong> literature that in the<br />

provision <strong>of</strong> initial consultation and ongoing care<br />

<strong>of</strong> patients, nurses can provide as high a quality<br />

<strong>of</strong> care as general practitioners. 23 In controlled<br />

trials in the UK, practice nurses were shown to<br />

be cost-effective in generating health gains for<br />

patients, particularly in areas <strong>of</strong> screening and<br />

health promotion. 23 <strong>The</strong> focus group interviews<br />

captured participants’ enthusiasm and motivation<br />

for learning, particularly that which will enhance<br />

their clinical skills and health outcomes for<br />

clients and their families.<br />

Participants emphasised their enjoyment <strong>of</strong><br />

their primary health care nursing role, and their<br />

intention to extend their practice within the<br />

general practice interdisciplinary team. Collaborative<br />

practice was identified as a facilitator which<br />

served to extend the practice nurse role, where<br />

the unique role <strong>of</strong> the practice nurse and GP can<br />

be retained and overlaps be identified. 10,11,24,25<br />

Continuing pr<strong>of</strong>essional education is essential<br />

to develop the breadth <strong>of</strong> the practice nurses’<br />

experience and knowledge, to improve levels <strong>of</strong><br />

job satisfaction as well as health outcomes for<br />

consumers <strong>of</strong> primary health care. 24<br />

Participants clearly articulated that the funding<br />

was the key enabler that has assisted them to<br />

engage in post-registration education. <strong>The</strong> cost <strong>of</strong><br />

education can be a significant barrier to improving<br />

nursing education opportunities. Postgraduate<br />

fees for a 30 credit course in 2009 were $1456<br />

and $1935 at the Universities <strong>of</strong> Canterbury and<br />

Otago respectively. 26,27 Accommodation and travel<br />

are additional costs. 22 Pegasus Health has been<br />

proactive in enabling post-registration education<br />

for practice nurses in Christchurch. Pegasus<br />

Health has provided scholarships for practice<br />

nurses to engage in certificate and diploma<br />

courses provided by the Christchurch Polytechnic<br />

Institute <strong>of</strong> Technology.<br />

Several challenges were identified in the focus<br />

group interviews regarding access to postregistration<br />

education. This included discussion<br />

around practice nurses wanting ‘to have a life’,<br />

as well as working and studying. Issues such as<br />

practice nurse career pathways were commented<br />

on. In 2000 the NZ <strong>College</strong> <strong>of</strong> Practice Nurses<br />

developed a career and pr<strong>of</strong>essional development<br />

framework. 28 A uniform, national primary health<br />

care nursing education framework is essential for<br />

the development <strong>of</strong> primary health care nursing<br />

roles. 29 <strong>The</strong>re is no mandatory training, or core<br />

pr<strong>of</strong>essional competencies for practice nurses<br />

in NZ or Australia and the result is ‘unacceptable<br />

variations in the quality <strong>of</strong> practice’ seen<br />

in NZ. 12,24,29 A suggestion from participants was<br />

the establishment <strong>of</strong> an appraisal system for all<br />

practice nurses, to recognise work-related achievements<br />

and highlight pr<strong>of</strong>essional development<br />

goals. <strong>The</strong> Health <strong>Practitioners</strong> Competence Assurance<br />

Act (2003) requires registered nurses to<br />

Participants emphasised their enjoyment <strong>of</strong> their<br />

primary health care nursing role, and their<br />

intention to extend their practice within the<br />

general practice interdisciplinary team<br />

maintain their currency by engaging in ongoing<br />

education, with a minimum <strong>of</strong> 60 hours pr<strong>of</strong>essional<br />

development every three years.<br />

Participants identified negotiating pr<strong>of</strong>essional<br />

development time with their employer as an<br />

<strong>issue</strong>. <strong>The</strong> discussion included practice nurses<br />

gaining support from their employer to embark<br />

on study, agreement about its relevance to the<br />

practice, obtaining funding for upgrading skills<br />

and leave to engage in study. A report <strong>of</strong> nursing<br />

developments in primary health care from 2001<br />

to 2007 found that a majority <strong>of</strong> general practitioners<br />

encouraged practice nurses to increase<br />

their role and 75% reported that practice nurses<br />

had taken on an increased role. 21 <strong>The</strong> Health<br />

Workforce Advisory Committee is concerned<br />

that the general practitioner workforce is in<br />

significant decline in relation to the population<br />

<strong>of</strong> <strong>New</strong> <strong>Zealand</strong>. 30 Thus the expansion <strong>of</strong> the<br />

practice nurse role could free up general practitioners’<br />

time and be more cost-effective for<br />

the practice. However, it might be necessary to<br />

establish some incentives for practice nurses to<br />

develop their extended roles and continue with<br />

post-registration education. <strong>The</strong>re was consensus<br />

that participants would like financial rewards for<br />

their educational achievements. Nurse leaders in<br />

NZ have suggested that the GP employment <strong>of</strong><br />

nurses should cease, and be replaced by a salaried<br />

model <strong>of</strong> employment by a PHO or DHB. 9 Providing<br />

financial incentives and recognition <strong>of</strong> the<br />

practice nurse’s extended roles has been recommended<br />

by Harrison et al. 31 Twelve participants<br />

spoke <strong>of</strong> wanting to see more acknowledgement<br />

from their GP employers as they felt they ‘have<br />

the qualifications’ but wanted to use their ‘full<br />

necessarily include obtaining nurse practitioner<br />

status, as they felt that this role required intensive<br />

study and practice and they were not sure if this<br />

potential’ in primary health care. All participants<br />

commented on their engagement in nursing innovation<br />

projects, where they have been given<br />

the opportunity to deliver nursing care in new<br />

ways, such as release time to conduct community<br />

or home visits and delivering care for clients and<br />

families with chronic conditions. <strong>The</strong>se new<br />

models <strong>of</strong> care have been cited by participants as<br />

motivators to maintain currency and to engage in<br />

post-registration education.<br />

Participants’ visions for practice nursing did<br />

not necessarily include obtaining nurse practitioner<br />

status, as they felt that this role required<br />

intensive study and practice and they were not<br />

sure if this was adequately rewarded financially.<br />

However, there was a shared vision emerging,<br />

where clients and families were aware <strong>of</strong> and<br />

utilised their potential. Pullon states ‘it is time<br />

practice nurses had due recognition, not only <strong>of</strong><br />

their unique skill set, but also <strong>of</strong> their undis-<br />

puted and essential place in primary care teams<br />

in general practices’. 32 Working collaboratively<br />

in the practice team was valued by participants.<br />

<strong>The</strong> government has proposed the establishment<br />

<strong>of</strong> multidisciplinary, integrated family health<br />

centres that reflect the participants’ vision. 33<br />

Strengths <strong>of</strong> this study<br />

This study involved a review <strong>of</strong> the current literature<br />

on primary health care nursing roles and<br />

post-registration education. <strong>The</strong> 16 participants<br />

provided in-depth understanding <strong>of</strong> the influences<br />

that promoted their engagement in post-registration<br />

education. All participants highlighted<br />

how pr<strong>of</strong>essional development complemented<br />

their clinical expertise, enhancing application <strong>of</strong><br />

theory to practice.<br />

Limitations<br />

<strong>The</strong> qualitative approach <strong>of</strong> the focus group<br />

interviews and the small number <strong>of</strong> participants<br />

prevents generalisations being made to the larger<br />

population <strong>of</strong> practice nurses. Only practice<br />

nurses employed by Pegasus Health were interviewed<br />

and this excluded nurses who work for<br />

other organisations who might have a different<br />

experience <strong>of</strong> accessing post-registration education.<br />

<strong>The</strong> convenience sampling method may have<br />

led to response bias, whereby the group <strong>of</strong> practice<br />

nurses who volunteered for the study may<br />

not have educational experiences representative<br />

<strong>of</strong> the population as a whole. However, the lack<br />

<strong>of</strong> a local practice nurse register precluded other<br />

sampling techniques.<br />

Implications<br />

It is important that practice nurses are supported<br />

to develop their roles in primary health care. This<br />

includes provision <strong>of</strong> educational opportunities<br />

and the development <strong>of</strong> a career pathway and<br />

educational framework. Participants indicated<br />

that Pegasus Health has actively encouraged their<br />

pr<strong>of</strong>essional development and provided opportunities<br />

to overcome barriers to post-registration<br />

education.<br />

Given its qualitative nature, this research could<br />

only explore what influences practice nurses to<br />

not reflect views <strong>of</strong> practice nurses who are not<br />

interested in further education or improving<br />

education would assist in broadening<br />

ABSTRACT<br />

Aim: Vaginal complaints cannot be definitively diagnosed in approximately one-third <strong>of</strong> women. We<br />

sought to determine if women without a diagnosis had higher levels <strong>of</strong> psychiatric disorders.<br />

Methods: This was an observational study in an urban family practice clinic. Prior to seeing a clinician,<br />

women with vaginal complaints completed the Patient Health Questionnaire (PHQ); symptoms were<br />

measured by the Vaginal Complaints Scale (VCS). Patients were then examined and treated by a family<br />

physician. At one and two weeks’ time patients were contacted by phone regarding symptom resolution<br />

and clinical outcomes.<br />

Results: We enrolled 47 patients; one patient was excluded. A diagnosis was made in 36. Eighteen<br />

had bacterial vaginosis, 16 had candida, three trichomonas, two HSV, one chlamydia; there were eight<br />

dual diagnoses. PHQ diagnoses were slightly less common in women without an identified cause for their<br />

symptoms. We obtained follow-up data from 45 subjects at one week and 34 subjects at two weeks’ time.<br />

At two weeks’ follow-up, 97% <strong>of</strong> subjects had complete resolution or improvement <strong>of</strong> their symptoms.<br />

Symptom improvement was equivalent among women with a diagnosis and those without. We estimate<br />

180 subjects would be needed to detect a clinically meaningful difference in PHQ diagnoses.<br />

Discussion: Our pilot study did not find an association between psychiatric diagnoses made by the<br />

PHQ and unexplained vaginal symptoms. Nearly all patients experienced rapid resolution <strong>of</strong> symptoms irrespective<br />

<strong>of</strong> whether a diagnosis had been made or not. <strong>The</strong>se findings are limited primarily by the small<br />

sample size.<br />

Introduction<br />

Vaginal complaints are common in primary care,<br />

yet comprehensive microbiologic investigations<br />

fail to identify an aetiology in about one-third <strong>of</strong><br />

cases. 1–4 Factors other than known microbes and<br />

dermatological reactions must, therefore, play a<br />

role in the development <strong>of</strong> vaginal complaints.<br />

Since vaginal symptoms can have important<br />

social meanings, 5–8 some investigators have<br />

postulated a role for psychosocial stress in their<br />

genesis. A population-based survey in India<br />

concluded that psychosocial factors were strongly<br />

associated with complaints <strong>of</strong> vaginal discharge,<br />

while reproductive tract infections (RTI) were<br />

not. 8 This may reflect specific cultural ideas in<br />

India concerning leucorrhoea (white vaginal discharge).<br />

7,9 Chronic stress has been linked to vaginal<br />

candidiasis. 10,11 Studies on the role <strong>of</strong> stress in<br />

bacterial vaginosis have been contradictory. 12–14<br />

No study has examined the relationship between<br />

medically unexplained vaginal symptoms and<br />

psychosocial stress. To explore this relationship,<br />

we hypothesised that if unexplained symptoms<br />

resulted from psychosocial factors, then we<br />

would find higher levels <strong>of</strong> depression, somatisation,<br />

anxiety symptoms and psychosocial stress in<br />

patients who did not have an RTI when compared<br />

to patients who did have an RTI. In addition, we<br />

evaluated the impact <strong>of</strong> a having made a specific<br />

diagnosis on the resolution <strong>of</strong> vaginal symptoms.<br />

Methods<br />

Subjects<br />

<strong>The</strong> study was conducted at an urban family practice<br />

clinic and residency training site. All women<br />

from 18 to 45 years presenting with vaginal complaints<br />

were eligible. Exclusion criteria included:<br />

fever; known diagnosis <strong>of</strong> gonorrhoea, chlamydia,<br />

or herpes; menstruation; and pregnancy. Women<br />

who had self-treated for vaginal symptoms were<br />

not excluded in order to assure a representative<br />

study population.<br />

Recruitment and consent<br />

Nurses queried all patients regarding their<br />

presenting problems. Patients with any vaginal<br />

complaints were referred to one <strong>of</strong> the authors<br />

(UA). Written informed consent was obtained<br />

from those who wished to participate.<br />

Study protocol<br />

Consenting patients completed a basic demographic<br />

survey, a sexual and contraceptive history,<br />

the Vaginal Complaints Scale (an 18-question survey<br />

designed by the authors) 15 and the depression,<br />

anxiety, somatisation, and stress sections <strong>of</strong> the<br />

self-report Patient Health Questionnaire (PHQ). 16<br />

Study patients were seen by their assigned clinical<br />

providers or by UA. All providers at the clinic<br />

are trained in the diagnosis <strong>of</strong> vaginitis. Resident<br />

physicians only examine patients under direct<br />

supervision <strong>of</strong> attending physicians. A pelvic<br />

examination was performed and a sample <strong>of</strong> the<br />

vaginal fluid obtained. <strong>The</strong> pH was measured, a<br />

whiff test performed, and the sample examined<br />

under a microscope using normal saline and potassium<br />

hydroxide (KOH). All specimens were reviewed<br />

by UA in addition to the primary clinician.<br />

Bacterial vaginosis (BV) was diagnosed using the<br />

Amsel Criteria. If microscopic examination did not<br />

reveal a definitive diagnosis, culture <strong>of</strong> yeast and<br />

T. vaginalis were obtained. Women were tested for<br />

gonorrhoea and chlamydia; physicians were free to<br />

order additional tests at their clinical discretion.<br />

What gap this fills<br />

What we already know: Vaginal complaints are very common in primary<br />

care, but a cause cannot be identified in one-quarter to one-third <strong>of</strong> women.<br />

Some evidence has suggested that psychosocial morbidity may account for<br />

unexplained vaginal symptoms.<br />

What this study adds: In this small pilot study, unexplained symptoms<br />

were not associated with measures <strong>of</strong> psychosocial distress. Most women<br />

experienced prompt relief <strong>of</strong> symptoms regardless <strong>of</strong> whether a diagnosis<br />

had been made or not.<br />

Patients with an identified microbe were treated<br />

by their primary care provider. Patients without<br />

a definitive diagnosis were either treated or not<br />

treated according to their provider’s assessment<br />

(typically based on the severity <strong>of</strong> symptoms or<br />

likelihood <strong>of</strong> disease on the basis <strong>of</strong> the pH or<br />

past history).<br />

Follow-up<br />

UA contacted subjects by phone at both one week<br />

and two weeks after initial presentation regarding<br />

symptom resolution, clinical outcomes, and<br />

any persistent patient concerns. Patients who<br />

remained symptomatic at the two-week follow-up<br />

call were referred for re-evaluation at the clinic.<br />

Infection with trichomonas or candida<br />

Reports indicating an RTI were returned to the<br />

primary care provider who initiated therapy for<br />

the patient and, when applicable, for their sexual<br />

partner(s).<br />

Positive screening for psychosocial <strong>issue</strong>s<br />

Patients with evidence <strong>of</strong> any mental disorder or<br />

family violence were <strong>of</strong>fered referral to a social<br />

worker.<br />

Data analysis<br />

Data was entered into an Access database and analysed<br />

using SPSS for Windows Version 15.0 s<strong>of</strong>tware.<br />

Group differences were evaluated with twotailed<br />

t-tests for independent samples or Fisher’s<br />

exact test. We analysed the vaginal symptom score<br />

using a hierarchical linear regression model with<br />

a random intercept at the individual level. Fixed<br />

basis <strong>of</strong> <strong>of</strong>fice tests (pH, microscopy, whiff test).<br />

Four additional diagnoses were made based on<br />

culture: one candida, one chlamydia and two<br />

herpes simplex (HSV). Taking into account both<br />

<strong>of</strong>fice diagnoses and culture, 15 women had BV<br />

alone, 13 women had candida alone, two women<br />

had trichomonas alone and two women had HSV.<br />

Four women had dual diagnoses: two with BV<br />

and candida, one with BV and chlamydia, and<br />

one with trichomonas and candida. No woman<br />

was diagnosed with a non-infectious cause <strong>of</strong><br />

vaginitis (contact dermatitis or allergic reactions).<br />

Ten patients (22%) were undiagnosed.<br />

Psychological distress and diagnosis<br />

Eleven women had diagnoses suggested from<br />

scoring the PHQ survey. Seven women had a<br />

single diagnosis: three had somatisation, two had<br />

minor depression and one each had panic and<br />

anxiety. Three women had dual diagnoses; one<br />

patient each had somatisation associated with either<br />

minor depression, major depression or panic<br />

disorder. One woman was diagnosed with minor<br />

depression, panic disorder, and anxiety. PHQ<br />

diagnoses were not more common in women<br />

without a medical diagnosis (Table 2).<br />

Symptom resolution<br />

We were able to contact 45 patients for follow-up<br />

at one week’s time (one lost to follow-up) and 33<br />

patients at two weeks’ time (13 lost to followup).<br />

At one week 21 (47%) patients had complete<br />

resolution <strong>of</strong> symptoms, 20 (44%) had partial<br />

resolution <strong>of</strong> symptoms and four (9%) reported no<br />

change in symptoms. At two weeks 22 (67%) were<br />

completely better, 10 (30%) were a little better<br />

and only one patient was no better. No patient reported<br />

that symptoms were worse at either time.<br />

Symptoms decreased markedly at the one week<br />

follow-up and decreased further at two weeks;<br />

these differences were statistically significant and<br />

occurred in both the diagnosis and non-diagnosis<br />

group. Differences in clinical resolution and<br />

symptom scores were not statistically different<br />

between the diagnosis and non-diagnosis groups.<br />

Table 2. Diagnoses and association with psychological distress<br />

Diagnosis<br />

Based on PHQ scoring<br />

We considered that three points on the Vaginal<br />

Complaints Scale represented a meaningful clinical<br />

difference. To have 80% power for detecting<br />

a difference <strong>of</strong> three using a two-tailed test with<br />

alpha = 0.05, and a correlation <strong>of</strong> zero between<br />

the baseline and follow-up measure would require<br />

91 people in each group.<br />

Discussion<br />

Women with a<br />

diagnosis (n=36)<br />

In this pilot study we failed to find increased<br />

levels <strong>of</strong> psychosocial distress in women with<br />

undiagnosed vaginal symptoms when compared<br />

to those who did have a diagnosis. Both groups <strong>of</strong><br />

patients experienced prompt symptomatic relief <strong>of</strong><br />

their symptoms. Thus, in terms <strong>of</strong> psychological<br />

distress and symptom resolution, patients in our<br />

study who went undiagnosed seemed indistinguishable<br />

from patients with a medical diagnosis.<br />

Our rate <strong>of</strong> non-diagnosis (22%) compares favourably<br />

to that reported in the medical literature as<br />

do our range <strong>of</strong> diagnoses. Our study is, however,<br />

limited by the small sample size, the convenience<br />

nature <strong>of</strong> the sample, relatively poor follow-up<br />

at two weeks (74%), and the fact that the PHQ is<br />

primarily a screening tool.<br />

<strong>The</strong> simplest explanation <strong>of</strong> our findings is that<br />

women without a medical diagnosis are reacting<br />

appropriately to bodily changes in the same way<br />

as women with an identified cause. This would<br />

suggest that there may be unidentified infectious<br />

pathogens or processes that are causing their<br />

symptoms. Another explanation is that psychosocial<br />

stress is causing them to over-react to normal<br />

bodily functions but that the levels <strong>of</strong> stress are<br />

equivalent to those <strong>of</strong> persons with symptoms<br />

caused by a pathogen. It may be that the PHQ<br />

that might be responsible for symptoms. It is important<br />

to note that even had we found association<br />

between unexplained vaginal symptoms and<br />

psychological distress at the time <strong>of</strong> presentation<br />

this would not necessarily imply that the distress<br />

caused the symptoms.<br />

Since one-quarter to one-third <strong>of</strong> women in<br />

primary care with vaginal symptoms go undiagnosed,<br />

a better understanding <strong>of</strong> their symptoms<br />

remains an important problem in primary care.<br />

<strong>New</strong> <strong>Zealand</strong> general practice should adopt<br />

population-based screening for attention<br />

deficit hyperactivity disorder (ADHD)<br />

YES<br />

One <strong>of</strong> the advantages <strong>of</strong> having been around in<br />

general practice for more than four decades is the<br />

opportunity to observe the long-term impact <strong>of</strong><br />

a change in thinking in one area <strong>of</strong> medicine and<br />

to ask the question ‘Why do we not deal with<br />

another area according to the same principles?’<br />

For example, in the diagnosis and management <strong>of</strong><br />

diabetes there has been a quiet revolution. When<br />

I first started in general practice we waited until<br />

a diabetic was symptomatic before assessing. <strong>The</strong><br />

usual opportunistic test was to check the urine<br />

for sugar. <strong>The</strong> received wisdom at that time was<br />

that most practices had 1% <strong>of</strong> known diabetes but<br />

that there was another 1% waiting to be detected<br />

if we looked a little harder. At the present time<br />

4% <strong>of</strong> my patients are known to be diabetic but I<br />

am told this is too low. Yes, the rate <strong>of</strong> diabetes<br />

has increased over 40 years because <strong>of</strong> increasing<br />

obesity, but the biggest change is the result<br />

<strong>of</strong> a serious population screening approach with<br />

tougher criteria. All the indications are that<br />

the benefits in patient outcome are substantial<br />

in moving some patients back from the edge <strong>of</strong><br />

diabetes and reducing end organ damage and<br />

therefore mortality.<br />

<strong>The</strong> same could be said <strong>of</strong> the management <strong>of</strong><br />

cardiovascular disease by screening for hypertension<br />

and hypercholesterolaemia, and treating<br />

early. We also have a much more aggressive<br />

approach to smoking cessation and altogether<br />

it is making a difference. No one suggests that<br />

the modern management <strong>of</strong> diabetes and heart<br />

disease is a waste <strong>of</strong> time and money.<br />

An equally strong case can be made for the detection<br />

<strong>of</strong> attention deficit hyperactivity disorder<br />

(ADHD) across the population. <strong>The</strong> generally<br />

agreed rate <strong>of</strong> ADHD in most populations is 5% 1<br />

or more, which translates into at least 200 000<br />

people <strong>of</strong> all ages in <strong>New</strong> <strong>Zealand</strong> (NZ). According<br />

to Pharmac figures, around 25 000 are<br />

currently receiving medication, which is less than<br />

13% <strong>of</strong> the possible total. <strong>The</strong>re may be another<br />

13% in whom a diagnosis <strong>of</strong> ADHD has been<br />

made, but in whom it has been decided by doctors,<br />

patients or families that medication is not<br />

appropriate. If these estimates are roughly correct<br />

there would still be around 74% who are undiagnosed.<br />

Does it matter?<br />

Various studies have found a massive social burden<br />

from ADHD. One claims that 25% <strong>of</strong> those<br />

in jail in the USA have ADHD. Another suggests<br />

that those with ADHD are 22 times more<br />

likely to be incarcerated at some time in life than<br />

While evidence can help inform best practice, it needs to be placed in context.<br />

<strong>The</strong>re may be no evidence available or applicable for a specific patient with<br />

his or her own set <strong>of</strong> conditions, capabilities, beliefs, expectations and social<br />

circumstances. <strong>The</strong>re are areas <strong>of</strong> uncertainty, ethics and aspects <strong>of</strong> care for which<br />

there is no one right answer. <strong>General</strong> practice is an art as well as a science. Quality<br />

<strong>of</strong> care also lies with the nature <strong>of</strong> the clinical relationship, with communication and<br />

with truly informed decision-making. <strong>The</strong> Back to Back section stimulates<br />

debate, with two pr<strong>of</strong>essionals presenting their opposing views regarding a clinical,<br />

ethical or political <strong>issue</strong>.<br />

those who do not. 2 <strong>The</strong> rate <strong>of</strong> road accidents was<br />

found to be four times higher in ADHD drivers. 3<br />

Substance abuse is double in ADHD, but reduced<br />

by treatment. 4 Academic underachievement, 5 job<br />

instability, 6 unemployment, relationship breakdowns,<br />

teenage pregnancy, and suicide are all<br />

significantly higher. Rates <strong>of</strong> other psychiatric<br />

illnesses including depression, anxiety, 7 schizophrenia,<br />

and OCD are all higher. A high proportion<br />

<strong>of</strong> Specific Learning Disorders have an underlying<br />

problem <strong>of</strong> ADHD. 8 <strong>The</strong> cost in terms<br />

<strong>of</strong> suffering for the patient and those around<br />

him or her is enormous. <strong>The</strong> financial cost to the<br />

Ministries <strong>of</strong> Education, Social Welfare, Justice,<br />

and Health (with particular reference to ACC)<br />

must be equally substantial. This latter amount<br />

would be many times the cost <strong>of</strong> a greater use <strong>of</strong><br />

medication where needed.<br />

Why then do we not take a wider approach to the<br />

detection <strong>of</strong> ADHD in our practices? <strong>The</strong>re are<br />

various excuses.<br />

1. Isn’t ADHD a new disease?<br />

<strong>The</strong> first good description <strong>of</strong> the condition was<br />

by Dr Alexander Crichton in 1798 and it was<br />

described more fully in 1902 by Dr Joseph Still.<br />

Effective treatment began in 1976. <strong>The</strong> current<br />

name is relatively new, first used in 1980 for<br />

children and in 1994 for adults, but the symptom<br />

complex was clear long before.<br />

2. ADHD is not a real condition, is it?<br />

Positron Emission Tomography first demonstrated<br />

in 1990 the difference in blood flow in key areas<br />

<strong>of</strong> the brain, and this was later shown to reverse<br />

with medication. <strong>The</strong> genetic factors are being<br />

rapidly defined. <strong>The</strong> test <strong>of</strong> variable attention<br />

(TOVA) computer test has 80% specificity and<br />

80% sensitivity. Endless RCTs <strong>of</strong> medication have<br />

shown easily measurable benefits in learning and<br />

behaviour from treatment.<br />

3. Isn’t ADHD a specialist condition?<br />

<strong>The</strong> diagnosis requires a careful history from<br />

the individual, the family and the teacher for<br />

children, and a wider circle for adults. It is a<br />

common problem. <strong>The</strong> management involves the<br />

family and the community and is long-term. <strong>The</strong><br />

medication is simple to titrate and safe. Aren’t<br />

these the very conditions GPs manage best? Only<br />

3% <strong>of</strong> general psychiatric patients are referred to<br />

psychiatrists in the public system. Why should<br />

ADHD be different?<br />

4. Doesn’t ADHD treatment<br />

leads to drug abuse?<br />

Studies have shown, on the contrary, that later<br />

drug abuse is substantially reduced by the early<br />

use <strong>of</strong> medication. <strong>The</strong> proportion <strong>of</strong> those<br />

receiving medication who abuse is less than 5%<br />

if they are strictly managed. Why punish the<br />

other 95%?<br />

5. Can’t ADHD be well-managed<br />

by better parenting, firm teaching,<br />

diet, and counselling?<br />

All <strong>of</strong> these measures may help, but only when<br />

appropriate medication is considered at the same<br />

time. Vast amounts <strong>of</strong> money are spent by desperate<br />

parents on alternative medicines and therapies<br />

for which there is no evidence <strong>of</strong> benefit.<br />

6. Isn’t ADHD only a childhood<br />

condition which they outgrow?<br />

ADHD is recognisable throughout life. About<br />

half <strong>of</strong> ADHD sufferers have adapted sufficiently<br />

by the end <strong>of</strong> the teens, but the other<br />

half need ongoing help.<br />

A population approach to ADHD would inevitably<br />

mean shifting responsibility for basic<br />

assessment and management to general practice.<br />

This, in turn, would necessitate training interested<br />

GPs to be able to undertake this effectively.<br />

9 More complex problems with multiple<br />

psychiatric diagnoses would still need specialist<br />

input. Tools, <strong>of</strong> which there are many, to<br />

assist diagnosis should be reviewed to establish<br />

suitability, effectiveness and reliability. Current<br />

barriers to the decision to prescribe stimulants<br />

would need to be modified. <strong>The</strong> rules<br />

have recently been relaxed to allow GPs to<br />

prescribe Isotretinoin in acne, arguably a more<br />

risky decision. Education <strong>of</strong> teachers, parents,<br />

and social workers would need to be under-<br />

taken to achieve a more harmonious working<br />

relationship to support ADHD patients. Funding<br />

for GPs with a special interest in this area<br />

to allow sufficient time for thorough assessment<br />

would need to be agreed.<br />

Singapore and South Korea, with similar rates<br />

<strong>of</strong> ADHD to NZ, are developing a population<br />

approach in which GPs are central. <strong>The</strong>y<br />

report that this is working well. What are we<br />

waiting for?<br />

<strong>New</strong> <strong>Zealand</strong> general practice should adopt<br />

population-based screening for attention<br />

deficit hyperactivity disorder (ADHD)<br />

NO<br />

Prevention <strong>of</strong> harm through screening is<br />

naturally a good thing to do—only a wowser<br />

would vote against it. However we work in a<br />

resource-limited system and so have to carefully<br />

consider where we should put our efforts. Over<br />

the years many new screening programmes have<br />

been proposed and then fallen by the wayside.<br />

As far back as 1968 the World Health Organization<br />

promoted a set <strong>of</strong> criteria to be met before a<br />

screening programme is adopted. <strong>The</strong>se include:<br />

Is it a well-defined and important disease? Does<br />

the population want the screening? Do we have<br />

a sensitive and specific test to help differentiate<br />

those at risk? Do we have an effective intervention,<br />

is the screening likely to lead to harm<br />

rather than benefit? Do we have evidence <strong>of</strong><br />

benefit from randomised controlled trials? Do we<br />

have the resources to implement the screening<br />

programme?<br />

So how does screening for attention deficit<br />

hyperactivity disorder (ADHD) stack up against<br />

these criteria? ADHD is a chronic behavioural<br />

disorder characterised by persistent hyperactivity,<br />

impulsivity, and inattention. 1 Its reported<br />

prevalence is greater in boys than girls, decreases<br />

with age and varies from country to country with<br />

the USA reporting as many as one in 20 children<br />

with a diagnosis <strong>of</strong> ADHD. 2 Many young people<br />

with signs <strong>of</strong> ADHD have comorbid conditions<br />

such as depression, conduct disorders, substance<br />

abuse and bipolar disease. 1 It is therefore difficult<br />

to determine what the natural history <strong>of</strong> ADHD<br />

is when many <strong>of</strong> the outcomes can be confounded<br />

by the comorbidities. Whilst we have quite good<br />

data on what happens to children with signs <strong>of</strong><br />

ADHD, 3 the progression and outcomes for adolescents<br />

and adults is less well documented. We do<br />

know that those with attention disorder in childhood<br />

are less likely to achieve academically, and<br />

are more likely to have accidents. <strong>The</strong>re is also<br />

an association with ADHD, conduct disorders in<br />

childhood and later use <strong>of</strong> drugs. 4 Given what<br />

we know about ADHD do we believe there is a<br />

demand for population-based screening in NZ? A<br />

number <strong>of</strong> screening programmes fail because <strong>of</strong><br />

poor uptake. <strong>The</strong> Before Schools Checks includes<br />

a screening test for behavioural problems—and<br />

the uptake to date has been poor. I suspect the<br />

uptake by adolescents and adults would be even<br />

worse. We would certainly need studies to<br />

ascertain the likely uptake before embarking on a<br />

population-based programme.<br />

One danger <strong>of</strong> a screening test is that it may<br />

lead to some patients being incorrectly labelled<br />

rectly labelled as having a condition which may<br />

have lifelong implications.<br />

<strong>The</strong> next key question is: do we have an effective<br />

intervention? Whilst there are good randomised<br />

controlled trials (RCTs) <strong>of</strong> a number<br />

<strong>of</strong> agents (e.g. methylphenidate, amphetamines,<br />

and desipramine) these are generally short-term<br />

studies and the outcomes measured are mainly<br />

reductions in symptom scores. 6 No one has<br />

had the money to show that long-term use <strong>of</strong><br />

methylphenidate has improved intellectual attainment,<br />

reduced driving accidents or helped<br />

with employment—the outcomes that matter.<br />

In the absence <strong>of</strong> long-term RCTs in a screened<br />

population it is unsafe to extrapolate the drug<br />

trials in highly selected populations to propose<br />

effectiveness. Longer term studies have shown<br />

large drop-out rates with older children being less<br />

likely to adhere to treatment. 7 Thus the efficacy<br />

<strong>The</strong> side effects <strong>of</strong> medication for ADHD are well recognised,<br />

but more important is their potential for abuse. Eleven percent<br />

<strong>of</strong> adolescents being treated in the USA reported selling their<br />

medication. Another concern is the harm generated by labelling<br />

a child or adolescent as having ADHD<br />

as having a disorder and subsequently being<br />

unnecessarily or incorrectly treated. <strong>The</strong>re are<br />

a number <strong>of</strong> screening tools for ADHD. Most<br />

are sensitive, but lack specificity. Consequently<br />

a second stage is required where those identified<br />

through screening are then reviewed and a<br />

diagnosis made. For ADHD this should involve<br />

a psychiatrist. It could be argued that general<br />

practitioners (GPs) are competent to accurately<br />

diagnose the condition. Whilst we do not know<br />

NZ GPs’ views on this, a Canadian study suggested<br />

95% <strong>of</strong> GPs would refer patients for a<br />

specialist opinion. 5 I would suspect that most NZ<br />

GPs would want to have an expert opinion—to<br />

ensure there was not a misdiagnosis <strong>of</strong> another<br />

psychiatric condition, to ensure comorbid conditions<br />

had been appropriately picked up, and <strong>of</strong><br />

course to make sure that people were not incor<strong>of</strong><br />

treatment in a screened population is likely to<br />

be much less than that found in short-term RCTs<br />

with selected patients. Is screening likely to<br />

lead to harm as well as benefit? <strong>The</strong> side effects<br />

<strong>of</strong> medication for ADHD are well recognised,<br />

but more important is their potential for abuse.<br />

Eleven percent <strong>of</strong> adolescents being treated in the<br />

USA reported selling their medication. 8 Another<br />

concern is the harm generated by labelling a child<br />

or adolescent as having ADHD.<br />

Finally, do we have the resources to implement<br />

a screening programme? <strong>The</strong> MaGPIe study<br />

noted that GPs felt that managing mental health<br />

problems took more time, the costs were likely to<br />

be subsidised by the practice as patients were not<br />

prepared to pay the full costs, and more training<br />

was needed if recognition <strong>of</strong> mental health<br />

problems was to be improved. 9 We should also<br />

recognise that there is a shortage <strong>of</strong> psychiatrists<br />

with expertise in the area and so waiting lists for<br />

assessment and diagnosis are likely to be long. <strong>The</strong><br />

opportunity costs both to GPs and mental health<br />

services are likely to be considerable and would<br />

require a reduction <strong>of</strong> activity in other areas.<br />

Let my review not be construed as saying ADHD<br />

is not important or that GPs should not be<br />

involved in its management. Rather I am saying<br />

that in patients and families who present for help,<br />

proper diagnosis and ongoing long-term support<br />

should be available. But I would suggest that the<br />

greatest utility is achieved by concentrating on<br />

the most severely affected, who have been identified<br />

by parents and teachers as being in need <strong>of</strong><br />

help. This does not mean we should leap into a<br />

screening programme.<br />

In summary, I would argue that ADHD does not<br />

meet the criteria for a screening programme. It<br />

is poorly defined, is frequently associated with<br />

comorbid mental health conditions and the health<br />

impact is not well quantified. Does the population<br />

want the screening? This is not known, but<br />

uptake in children has been poor. Do we have<br />

a sensitive and specific test to help differentiate<br />

those at risk? A variety <strong>of</strong> tests are available,<br />

but different tests are better for different age<br />

groups, they are time-consuming and doctors or<br />

their staff would need training. In the hands <strong>of</strong><br />

experts they are generally sensitive, but followup<br />

diagnosis is required. Do we have an effective<br />

intervention? <strong>The</strong>re are a number <strong>of</strong> medications<br />

that have shown symptom reduction in shortterm<br />

studies, but longer-term drop-out rates<br />

are high and the evidence <strong>of</strong> long-term benefit<br />

for outcomes that matter is poor. Is the screening<br />

likely to lead to harm rather than benefit?<br />

Adverse aspects <strong>of</strong> labelling and diversion <strong>of</strong><br />

drugs into the illicit market are likely to be a<br />

problem. Do we have the resources to implement<br />

managing mental health problems takes more<br />

time, more training is required and the additional<br />

costs are likely to be borne at least in part by GPs.<br />

NSAIDs for dysmenorrhoea<br />

Bruce Arroll MBChB, PhD, FRNZCGP; Pr<strong>of</strong>essor <strong>of</strong> <strong>General</strong> Practice<br />

and Primary Health Care, <strong>The</strong> University <strong>of</strong> Auckland, Private Bag 92019,<br />

Auckland, <strong>New</strong> <strong>Zealand</strong>; b.arroll@auckland.ac.nz<br />

<strong>The</strong> problem: Dysmenorrhoea is a common gynaecological<br />

problem consisting <strong>of</strong> painful cramps accompanying menstruation<br />

which, in the absence <strong>of</strong> any underlying abnormality, is<br />

known as primary dysmenorrhoea.<br />

<strong>The</strong> situation: Research has shown that women with<br />

dysmenorrhoea have high levels <strong>of</strong> prostaglandins, hormones<br />

known to cause cramping abdominal pain. Nonsteroidal<br />

anti-inflammatory drugs (NSAIDs) are drugs which act by<br />

blocking prostaglandin production. Pain is usually centred in<br />

the suprapubic area, but may radiate to the back <strong>of</strong> the legs<br />

or lower back, and may be accompanied by other symptoms<br />

such as nausea, diarrhoea, headache and lightheadedness. <strong>The</strong><br />

prevalence estimates vary widely. It was reported by 72% <strong>of</strong><br />

Australian women <strong>of</strong> reproductive age in a recent nationallyrepresentative<br />

sample and caused severe pain in 15% <strong>of</strong> cases.<br />

Other representative samples report rates ranging from 17% to<br />

81%. In addition to the distress associated with dysmenorrhoea,<br />

surveys have shown significant socioeconomic repercussions:<br />

over 35% <strong>of</strong> female high school students report missing school<br />

due to menstrual pain and 15% <strong>of</strong> working.<br />

Clinical bottom line: All NSAIDs are effective for<br />

dysmenorrhoea and there does not seem to be one better than<br />

others. It was not possible to report a numbers needed to treat<br />

from the review, but in one <strong>of</strong> the typical papers it was about<br />

five. <strong>The</strong> review did not suggest when to start taking the<br />

medication, but some <strong>of</strong> the studies advised to start taking the<br />

medication at the onset <strong>of</strong> first cramps.<br />

Ginkgo<br />

Ginkgo biloba L., also known as fossil tree,<br />

kew tree, maidenhair tree, yin xing (whole plant),<br />

yin xing ye (leaves), bai guo (seeds)<br />

Preparations: <strong>The</strong> leaf is the part used medicinally;<br />

in Traditional Chinese Medicine and<br />

in Japan, the seed is also used, although it contains<br />

some toxic constituents. Extracts <strong>of</strong> ginkgo<br />

leaf are available in several dose forms, including<br />

capsules, tablets and tinctures. Chopped or<br />

powdered forms <strong>of</strong> the dried material are also<br />

available. Several products marketed as dietary<br />

supplements containing ginkgo are available on<br />

the <strong>New</strong> <strong>Zealand</strong> market.<br />

Active constituents: Ginkgo has been<br />

described as having polyvalent action; that is, the<br />

combined activities <strong>of</strong> several constituents are<br />

responsible for its effects. Important constituents<br />

<strong>of</strong> the leaves include the ginkgo flavonoid glycosides<br />

(e.g. glycosides <strong>of</strong> quercetin and kaempferol)<br />

and the terpene lactones (e.g. ginkgolides<br />

A, B and C). Modes <strong>of</strong> action demonstrated in<br />

preclinical studies include cardiovascular and<br />

haemorheological effects, antagonism <strong>of</strong> plateletactivating<br />

factor, antioxidant activity and effects<br />

on concentrations <strong>of</strong> certain neurotransmitters.<br />

Seeds contain ginkgotoxin (4-O-methylpyridoxine)<br />

and ginkgolic acids.<br />

Main uses: Ginkgo leaf and seed have a history<br />

<strong>of</strong> traditional use in China for asthma and the seed<br />

also as an antitussive and expectorant. Contemporary<br />

interest in ginkgo leaf is focussed on its use<br />

in cognitive deficiency and dementia, intermittent<br />

claudication (from peripheral arterial occlusive<br />

disease) and vertigo and tinnitus <strong>of</strong> vascular origin.<br />

It is also used and promoted for cognitive improvement<br />

in healthy individuals.<br />

Evidence for efficacy: Recent Cochrane<br />

systematic reviews are available <strong>of</strong> clinical trials<br />

that assessed the effects <strong>of</strong> standardised ginkgo<br />

leaf preparations in cognitive impairment and dementia,<br />

intermittent claudication, acute ischaemic<br />

stroke, tinnitus and age-related macular degeneration.<br />

<strong>The</strong>se reviews conclude that there is no convincing<br />

evidence available to support the efficacy<br />

<strong>of</strong> the ginkgo preparations tested in cognitive impairment<br />

and dementia, intermittent claudication,<br />

recovery after ischaemic stroke and tinnitus; there<br />

was insufficient research to determine whether<br />

or not ginkgo is efficacious in age-related macular<br />

degeneration. Many trials, particularly older ones,<br />

have methodological limitations.<br />

A Cochrane systematic review <strong>of</strong> trials <strong>of</strong> ginkgo<br />

for cognitive improvement in healthy individuals<br />

is in preparation.<br />

Adverse effects: Typically, Cochrane systematic<br />

reviews <strong>of</strong> (usually small-scale) clinical trials<br />

have not shown any difference between ginkgo and<br />

placebo with respect to the frequency <strong>of</strong> adverse<br />

events, including bleeding episodes. However, spontaneous<br />

reports <strong>of</strong> adverse effects associated with<br />

the use <strong>of</strong> ginkgo preparations have raised concerns<br />

about the risk <strong>of</strong> haemorrhagic reactions, including<br />

intracranial and ocular bleeding. Many <strong>of</strong> these<br />

cases concern individuals who were also taking conventional<br />

antiplatelet and/or anticoagulant agents,<br />

although some concerned use <strong>of</strong> ginkgo only.<br />

indicated that ginkgo leaf extracts generally had no<br />

charms & harms<br />

Summary message<br />

Evidence for the efficacy <strong>of</strong> ginkgo extracts for cognitive impairment and<br />

dementia, intermittent claudication, acute ischaemic stroke, tinnitus and<br />

age-related macular degeneration is unconvincing. Ginkgo preparations<br />

have been associated with haemorrhagic reactions. Health pr<strong>of</strong>essionals<br />

should be aware <strong>of</strong> the possibility <strong>of</strong> (undisclosed) use <strong>of</strong> ginkgo; use <strong>of</strong><br />

ginkgo should be avoided, or at least used only with caution, in patients with<br />

bleeding disorders and those taking conventional anti-platelet or anticoagulant<br />

agents. If using ginkgo, these patients should be advised to be vigilant<br />

for signs <strong>of</strong> bleeding and to seek pr<strong>of</strong>essional help. Suspected adverse drug<br />

reactions should be reported to CARM. As with all herbal medicines, different<br />

ginkgo products vary in their pharmaceutical quality, and the implications<br />

<strong>of</strong> this for efficacy and safety should be considered.<br />

statistically significant effects on antiplatelet effects<br />

and/or pharmacokinetics <strong>of</strong> clopidogrel or ticlopidine,<br />

or on the pharmacokinetics and pharmacodynamics<br />

(INR) <strong>of</strong> warfarin. However, these studies<br />

involved healthy volunteers and the relevance <strong>of</strong><br />

these findings to the clinical setting is unclear.<br />

It is prudent to advise that use <strong>of</strong> ginkgo should be<br />

avoided in patients with bleeding disorders, since it<br />

is unlikely that the benefit–harm balance is favourable<br />

on the basis <strong>of</strong> current evidence. Likewise,<br />

ginkgo should only be used with caution in patients<br />

taking anticoagulant and/or antiplatelet agents.<br />

Some authors advise that the evidence is insufficient<br />

to advise patients taking such medicines to avoid<br />

using ginkgo. If ginkgo is used, patients should be<br />

advised to monitor for bruising and other signs <strong>of</strong><br />

bleeding, and to seek pr<strong>of</strong>essional help if this occurs.<br />

Contact with or ingestion <strong>of</strong> the fruit pulp can<br />

cause severe allergic reactions.<br />

Health pr<strong>of</strong>essionals are reminded to report<br />

suspected adverse reactions associated with all<br />

medicines, including vaccines and complementary<br />

medicines, to the Centre for Adverse Reactions<br />

Monitoring (http://carm.otago.ac.nz).<br />

Drug interactions: See Adverse effects for<br />

information on interactions with antiplatelet/anticoagulant<br />

agents.<br />

Drug interaction studies involving healthy volunteers<br />

who received ginkgo leaf extracts have<br />

indicated that ginkgo induces the metabolism and<br />

lowers concentrations <strong>of</strong> omeprazole; it is unlikely<br />

that the benefit–harm balance for using ginkgo in<br />

patients being treated with omeprazole would be<br />

favourable on the basis <strong>of</strong> current evidence. Similar<br />

studies have shown that ginkgo leaf extracts did<br />

not appear to have clinically relevant pharmacokinetic<br />

interactions with alprazolam, caffeine, chlorzoxazone,<br />

dextromethorphan, dicl<strong>of</strong>enac, digoxin,<br />

donepezil, fex<strong>of</strong>enadine, flurbipr<strong>of</strong>en, midazolam,<br />

propranolol, ritonavir, theophylline or tolbutamide.<br />

<strong>The</strong>re is limited evidence from preclinical studies<br />

that the administration <strong>of</strong> ginkgo and amikacin<br />

may accelerate amikacin-induced ototoxicity, and<br />

that ginkgo may lead to raised concentrations <strong>of</strong><br />

diltiazem and nifedipine and reduced concentrations<br />

<strong>of</strong> nicardipine. <strong>The</strong>re is also some limited<br />

clinical evidence <strong>of</strong> an interaction with nifedipine.<br />

<strong>The</strong>re is a small number <strong>of</strong> isolated case reports <strong>of</strong><br />

breakthrough seizures in patients taking sodium<br />

valproate, with or without phenytoin, in patients<br />

who began taking ginkgo leaf extract or were<br />

taking several products containing ginkgo. Until<br />

further information is available, patients should be<br />

made aware <strong>of</strong> this possible interaction.<br />

A whanau ora approach to<br />

health care for Maori<br />

Jacquie Kidd PhD, RN; 1 Veronique Gibbons MSc, BSc(Hons), RN; 2 Ross Lawrenson MD, FRCGP, FFPH,<br />

FAFPHM; 2 Wayne Johnstone MA (Hons), BA 3<br />

A<br />

whanau ora approach to health care is<br />

becoming well-established within the<br />

primary health care sector, which means<br />

that we now see many providers, particularly<br />

Maori providers, employing whanau ora workers<br />

who work not just directly with individuals<br />

but with families to help to support individuals<br />

<strong>of</strong>ten with chronic disease or mental health<br />

problems. At the same time a number <strong>of</strong> important<br />

initiatives have emerged including marae<br />

and community-based clinics which emphasise<br />

a positive approach to Maori health, philosophy<br />

and models. However, it is evident that there are<br />

subtle variations in how people and organisations<br />

perceive a whanau ora approach; indeed it is an<br />

approach that is used not only in health but in<br />

education and the social welfare sector. It should<br />

also be acknowledged that there may be local<br />

and iwi-based differences in understanding what<br />

whanau ora is.<br />

<strong>The</strong> term whanau ora was promoted by Mason<br />

Durie 1 as the component <strong>of</strong> good health that<br />

relates to the support from and connection to<br />

the family. Since then the term has been more<br />

widely used to affirm the importance <strong>of</strong> whanau<br />

planning and management <strong>of</strong> their own health<br />

including wairua (spirituality), te ao Maori (the<br />

Maori way <strong>of</strong> living in the world), tikanga (Maori<br />

customs and protocols), self-determination, and<br />

economic and social factors. This broadened view<br />

<strong>of</strong> health is part <strong>of</strong> the government’s Maori policy<br />

document He Korowai Oranga and is defined<br />

as ‘Maori families supported to achieve their<br />

maximum health and wellbeing.’ 2 Ora relates to<br />

well-being or health. When paired with whanau,<br />

the meaning is expanded to suggest the health<br />

and well-being <strong>of</strong> the family within the environment<br />

in which they interact. A more modern<br />

translation <strong>of</strong> whanau represents not only blood<br />

relations but also the relationship through a common<br />

goal or similar interests. 3<br />

Throughout the various District Health Boards,<br />

Maori providers and other health service providers,<br />

whanau ora has been used as a guiding<br />

principle and value, a goal, and in some instances<br />

it has been used to describe a type <strong>of</strong> health<br />

service being delivered to local Maori communities.<br />

While each has varying definitions on what<br />

whanau ora is to their particular region and/<br />

or service, it is clear that the overall goal is to<br />

achieve maximum wellness for the whanau.<br />

When structuring a kaupapa Maori research<br />

project that explores the whanau ora experiences<br />

<strong>of</strong> Maori men who have chronic disease or cancer,<br />

our team <strong>of</strong> Maori and non-Maori clinicians,<br />

academics and health care service managers<br />

concluded that the development <strong>of</strong> a local understanding<br />

<strong>of</strong> whanau ora was required. Bishop, 4<br />

methodology, includes the principles <strong>of</strong><br />

whakapapa (genealogy), whanau, te reo<br />

(language), tikanga, rangatiratanga (selfdetermination),<br />

and aroha ki te tangata<br />

(respect, accountability and valuing all<br />

those involved with and affected by<br />

the research). In addition to providing<br />

a sound cultural and ethical basis for<br />

the proposed research, 5 these principles<br />

are congruent with the generic research<br />

aims and form a basis to what Cram 6<br />

describes as talk as data.<br />

To this end, the Oranga Tane project<br />

team sought guidance from Waikato<br />

Kaumatua to determine what a local<br />

definition <strong>of</strong> whanau ora might look<br />

like. This was done through a series <strong>of</strong><br />

hui (meetings) held with local Kaumatua<br />

in each <strong>of</strong> the Tainui iwi areas: Waikato,<br />

Maniapoto, Raukawa and Pare Hauraki.<br />

Hui are an oral and aural medium for<br />

discussing, debating and coming to a<br />

shared understanding about <strong>issue</strong>s, and<br />

have a defined process to follow; this<br />

was undertaken by the Kaumatua for the<br />

research team, Kingi Turner. Kaumatua,<br />

defined as men and women elders who<br />

are guardians <strong>of</strong> genealogy, spirituality<br />

and Maori knowledge, were invited<br />

through their particular marae-based<br />

organisations to attend the hui and respond<br />

to the researchers’ request to ‘tell<br />

us what you understand by the term<br />

whanau ora.’ <strong>The</strong> ensuing discussion was<br />

captured on a whiteboard by a member<br />

<strong>of</strong> the research team who is fluent in te<br />

reo Maori. This ensured that the content<br />

<strong>of</strong> the discussion was accurately recorded<br />

and provided the participants with the<br />

opportunity to correct any misunderstandings<br />

or missed points as an integral<br />

part <strong>of</strong> the hui process.<br />

Although the overall aim <strong>of</strong> the study<br />

is focussed on Maori men, the guidance<br />

that came from Kaumatua encompassed<br />

the whanau as a whole. <strong>The</strong> well-being <strong>of</strong><br />

mokopuna (grandchildren) was a focus,<br />

with many discussions about the importance<br />

for all the whanau to stay healthy<br />

so the children’s well-being could be<br />

assured. Other areas <strong>of</strong> interest included<br />

the importance <strong>of</strong> whanau-based<br />

health education and the importance <strong>of</strong><br />

wairuatanga (spiritual connection) to<br />

health, although the hui also acknowledged<br />

a general reluctance to attend<br />

health screening and early treatment, the<br />

perceived unfriendliness <strong>of</strong> Westernbased<br />

health services, and the difficulties<br />

for some whanau who need to travel to a<br />

main centre to access health services.<br />

<strong>The</strong> <strong>issue</strong> <strong>of</strong> who speaks or acts on<br />

behalf <strong>of</strong> the whanau was also explored,<br />

with some <strong>of</strong> the Kaumatua arguing for<br />

a departure from the traditional gender<br />

separation <strong>of</strong> women’s and men’s health<br />

information. It was proposed that the<br />

whanau as a whole should be aware <strong>of</strong><br />

the health needs <strong>of</strong> their members, and<br />

be prepared to advocate and encourage<br />

self-care for the well-being <strong>of</strong> the wider<br />

whanau. <strong>The</strong>se concerns are common to<br />

international indigenous populations. 7<br />

In addition, wide-ranging discussions<br />

took place about how to connect te ao<br />

Maori, whanau, and health care services<br />

so that whanau ora is achieved. <strong>The</strong> need<br />

for health services to be integrated into<br />

social and economic services was clearly<br />

articulated, and is consistent with national<br />

policy directions. 8<br />

What became clear throughout the hui<br />

is that whanau ora is complex, with<br />

many interconnecting facets. Our findings<br />

indicate that difficulties accessing<br />

primary health care remains an <strong>issue</strong> for<br />

Maori, despite an apparent awareness <strong>of</strong><br />

the need for health screening and early<br />

treatment. It appears that there is a still<br />

unmet need for culturally-appropriate<br />

health care to improve acceptability <strong>of</strong><br />

health care provision. <strong>The</strong> Kaumatua<br />

were emphatic about the need for their<br />

whanau to be engaged with health care<br />

education, which they viewed as being<br />

important for the future health <strong>of</strong> their<br />

mokopuna. <strong>The</strong> value <strong>of</strong> the whanau<br />

ora approach is that the connections<br />

between health care providers, the world<br />

<strong>of</strong> Maori and the people <strong>of</strong> the whanau<br />

are made explicit and measurable. Maori<br />

community health workers provide<br />

general practitioners and others with<br />

the opportunity for such connections to<br />

be made and for improved health care<br />

outcomes for Maori. 9<br />

Overall we have presented in this paper<br />

the beginnings <strong>of</strong> a local whanau ora<br />

definition which is consistent with the<br />

understanding shown in a number <strong>of</strong><br />

studies to have improved access and<br />

health outcomes. We would encourage<br />

primary health care workers to work<br />

with Maori providers and others who<br />

are involved in whanau ora provision<br />

to avail themselves <strong>of</strong> this expertise<br />

in order to improve outcomes for their<br />

Maori patients.<br />

Too much information?<br />

Grant Gillett MBChB, D.Phil (Oxon), FRS NZ, FRACS; Donald Saville-Cook BSc, PGDip.HealSci (Otago), D.E.T.C.C.<br />

A<br />

number <strong>of</strong> recent cases have<br />

raised the <strong>issue</strong> <strong>of</strong> the risks that<br />

are posed both by everyday<br />

medicines and by alternatives to standard<br />

medical interventions, an aspect <strong>of</strong><br />

practice that has been made especially<br />

significant by the recent NZ Medical<br />

Council advice about fringe medicine 1<br />

and from the tendencies in contemporary<br />

medical literature and social policy<br />

to favour what can be referred to as<br />

‘marketing-based medicine’ masquerading<br />

as evidence-based medicine. 2<br />

<strong>The</strong> partial and selective information<br />

provided by the medical establishment<br />

raises questions about how many risks we<br />

should unwittingly run or be allowed to<br />

run by our medical advisors. <strong>The</strong> answer<br />

to this question must, however, be balanced<br />

against two other considerations in<br />

the area <strong>of</strong> information and disclosure.<br />

i. An ordinary consulting doctor,<br />

within the constraints <strong>of</strong> a clinical<br />

practice, cannot be expected to run<br />

through all the potentially relevant<br />

information relating to a condition<br />

and its management as part <strong>of</strong> a<br />

normal consultation with a patient,<br />

although there must be some required<br />

level <strong>of</strong> diligence.<br />

ii. Although the doctor has a legally well-<br />

established duty to answer a patient’s<br />

questions truthfully and to the best<br />

<strong>of</strong> their ability, the patient should not<br />

have to play a macabre game <strong>of</strong> 20<br />

questions to find out about aspects <strong>of</strong><br />

their condition and its treatment that<br />

they might regard as significant.<br />

<strong>The</strong> problem <strong>of</strong> information and what is<br />

required to satisfy rights 5 and 6 <strong>of</strong> the<br />

<strong>New</strong> <strong>Zealand</strong> Code <strong>of</strong> Health and Disability<br />

Services Consumers’ Rights 3 is<br />

made pressing by two possibilities. <strong>The</strong><br />

first is the existence <strong>of</strong> potentially very<br />

serious but systematically downplayed<br />

or concealed side effects from heavily<br />

marketed and promoted medications<br />

(such as statins) and the second is the existence<br />

<strong>of</strong> unorthodox or fringe regimens<br />

for diseases with a standard therapeutic<br />

pr<strong>of</strong>ile (such as psychiatric syndromes or<br />

cardiovascular disease).<br />

A case study<br />

Statin therapy has been associated with<br />

some serious and poorly documented side<br />

effects in that there is a link between not<br />

only myalgia but also rhabdomyolysis<br />

and statins. 4,5 Various reports in sources<br />

ranging from <strong>The</strong> American Journal <strong>of</strong><br />

Medicine to <strong>The</strong> <strong>New</strong> York Times have<br />

listed multiple neuromuscular conditions<br />

associated with statins, although this evidence,<br />

by its very nature, may be underreported<br />

because <strong>of</strong> its varying severity.<br />

A number <strong>of</strong> patients may well not be<br />

told <strong>of</strong> this association and its potentially<br />

life-affecting consequences, despite the<br />

fact that it is alluded to in the drug<br />

information, in part, because <strong>of</strong> the lack<br />

<strong>of</strong> emphasis on this aspect <strong>of</strong> the drugs in<br />

the literature and the widely publicised<br />

prophylactic benefits <strong>of</strong> statins. <strong>The</strong><br />

importance <strong>of</strong> prevention <strong>of</strong> heart attacks<br />

and strokes (and the attendant mortality<br />

and morbidity) makes us very ready to<br />

swallow the industry message (not to say<br />

the pills). <strong>The</strong>refore, even if patients have<br />

a right to know about such problems,<br />

it is not clear to what extent a doctor<br />

should foreground them (despite the clear<br />

warnings on the Medsafe website) nor to<br />

what extent s/he could be the subject <strong>of</strong><br />

complaints that potentially debilitating<br />

side effects were not mentioned. Given<br />

that patients <strong>of</strong>ten take their cue from the<br />

doctor about what is relevant to discuss in<br />

a clinic appointment, the omission could<br />

be serious in certain cases.<br />

<strong>The</strong> second problem is posed by the<br />

recent NZ Medical Council advice in its<br />

THIS ISSUE: Grant Gillett, Pr<strong>of</strong>essor <strong>of</strong> Medical Ethics from Otago, and his colleague,<br />

Donald Saville-Cook, address the <strong>issue</strong> <strong>of</strong> how much information needs to be given<br />

to patients, firstly about serious and potentially life-threatening adverse effects <strong>of</strong><br />

commonly-prescribed medications (such as statins) and, secondly, our duty to raise the<br />

options <strong>of</strong> radical or fringe treatments, and then explain why risk might outweigh benefit.<br />

VOLUME 2 • NUMBER 2 • JUNE 2010 J OURNAL OF PRIMARY HEALTH CARE 165


ethics<br />

Ethics 101 column. 6 <strong>The</strong> tone <strong>of</strong> the piece<br />

is to equate all non-orthodox practices<br />

with quackery or fraud and to dismiss<br />

them out <strong>of</strong> hand. But the idea that our<br />

biomedical theories are fully adequate to<br />

the intractable bestiary <strong>of</strong> ‘medicine in<br />

the (urban) jungle’ is a gross simplification.<br />

In reality, a complex nexus <strong>of</strong> socioeconomic<br />

variables, genetic dispositions,<br />

patterns <strong>of</strong> referral and categorisation,<br />

market-based selection <strong>of</strong> disseminated<br />

medical information, and so on, 2 and the<br />

rise <strong>of</strong> the psycho-neuro-humero-immunological<br />

concepts <strong>of</strong> human health and<br />

disease muddy the waters. 7 What, given<br />

this mish-mash and the lack <strong>of</strong> undistorted<br />

and scientific evidence relating to<br />

wide swathes <strong>of</strong> medical practice such<br />

as primary care, community psychiatry,<br />

and everyday unwellness, ought one to<br />

say and do?<br />

mentioned to patients with OCD or<br />

depression? We seem to be on notice by<br />

the Medical Council <strong>of</strong> NZ that if that<br />

were done they would not regard the<br />

practice as ethical, but the HDC code<br />

Right 6(a) demands <strong>of</strong> providers ‘an<br />

explanation <strong>of</strong> the options available’ 3 (<strong>of</strong><br />

which more anon). Suppose the patient<br />

found prescribed alternatives distressing<br />

or to have unwanted side effects (like<br />

weight gain)? <strong>The</strong> well-intentioned and<br />

patient-centred doctor is likely to be in<br />

a quandary in such a case, particularly<br />

if the patient is one in whom untoward<br />

events might be predicted. One might<br />

want to mention the possibility <strong>of</strong><br />

something a bit ‘fringe’ but what is the<br />

ethical stance to doing so? It seems that<br />

the patient is entitled to a fair representation<br />

<strong>of</strong> current medical opinion and<br />

answer problematic. <strong>The</strong>re obviously<br />

needs to be some kind <strong>of</strong> weighting<br />

<strong>of</strong> advice about risks, but how should<br />

that be done. <strong>The</strong> language <strong>of</strong> material<br />

risk—the kind <strong>of</strong> risk a reasonable person<br />

would take into account in making<br />

a decision—that is <strong>of</strong>ten used does not<br />

tell us how well established those risks<br />

should be. A risk <strong>of</strong> rhabdomyolysis or<br />

polyneuropathy is likely to be material<br />

to anyone even though it is rare,<br />

and common problems like myalgia<br />

are plausibly material in that the kind<br />

<strong>of</strong> group who take statins might find<br />

their physical activity significantly<br />

compromised by such a side effect. But<br />

these may not be foregrounded in the<br />

information available to the average<br />

practitioner, so that the question arises<br />

as to what constitutes due diligence in<br />

<strong>The</strong> problem is intensified when we<br />

consider cases such as the following: an<br />

18-year-old male underwent cognitive<br />

behavioural therapy for severe obsessive<br />

compulsive disorder (OCD) and depression<br />

which had the effect <strong>of</strong> mitigating<br />

it from severe to moderate. He then<br />

underwent an ‘ABAB, (n <strong>of</strong> 1)’ trial <strong>of</strong><br />

a nutritional formula during which ‘his<br />

mood stabilised, his anxiety reduced,<br />

and his obsessions were in remission’. 8<br />

A return to normal diet provoked a relapse<br />

in his symptoms. This single case<br />

study may never be supported by any<br />

‘robust clinical evidence’ considering<br />

patterns <strong>of</strong> research funding, publication<br />

and promulgation in contemporary<br />

medicine, 9 quite apart from the reality<br />

<strong>of</strong> the situation. Nevertheless it is the<br />

kind <strong>of</strong> case behind the major damages<br />

awarded to Truehope as a result <strong>of</strong> a<br />

class 1 withdrawal <strong>of</strong> drugs required by<br />

Health Canada. 10<br />

This is a classical example <strong>of</strong> fringe<br />

medicine (contra the Medical Council<br />

document, 3 rationally and scientifically<br />

reported and assessed) but should<br />

the option it reports be <strong>of</strong>fered or even<br />

Perhaps all that one can say is that the doctor should be a<br />

trustworthy guide and partner in the information sharing<br />

required for effective treatment, a role that is hard to<br />

specify but that is a key element <strong>of</strong> good clinical practice<br />

one should probably position the advice<br />

being given against that framework in<br />

any consultation. 11<br />

A number <strong>of</strong> further questions arise<br />

from these problems about the ethics<br />

<strong>of</strong> medical information and the responsibilities<br />

<strong>of</strong> doctors in their advice to<br />

patients.<br />

To what extent are patients<br />

entitled to information about<br />

risks <strong>of</strong> their treatment?<br />

A number <strong>of</strong> blanket statements state<br />

that a patient is entitled to know <strong>of</strong> any<br />

significant risks associated with a proposed<br />

course <strong>of</strong> treatment (as in Right<br />

6.1(b) <strong>of</strong> the code) but the existence <strong>of</strong><br />

contested or unusual risks makes that<br />

accessing the relevant information, a<br />

problem compounded by the abundance<br />

<strong>of</strong> medical information <strong>of</strong> varying quality<br />

on the Internet.<br />

How should doctors deal with risks<br />

that a patient has found about<br />

from the Internet and other sites?<br />

Here one faces the nightmare scenario<br />

<strong>of</strong> the patient who ‘cannot see the<br />

wood for the trees’. <strong>The</strong>re are in every<br />

practice patients who will make a major<br />

<strong>issue</strong> out <strong>of</strong> a possibility that most<br />

people would not be overly concerned<br />

about to the point where they might<br />

make bad decisions from a faulty appraisal<br />

<strong>of</strong> the evidence available. <strong>The</strong><br />

idea <strong>of</strong> truly patient-centred medicine<br />

takes us a certain way in that the doc-<br />

166 VOLUME 2 • NUMBER 2 • JUNE 2010 J OURNAL OF PRIMARY HEALTH CARE


ethics<br />

tor should assess the patient and the<br />

ways in which the patient is likely to<br />

distort or misinterpret evidence in the<br />

light <strong>of</strong> idiosyncratic personality factors<br />

so as to form a harmful or prejudicial<br />

opinion about their illness and its management.<br />

But one can imagine pitfalls<br />

aplenty in certain cases. Perhaps all that<br />

one can say is that the doctor should<br />

be a trustworthy guide and partner in<br />

the information sharing required for<br />

effective treatment, a role that is hard<br />

to specify but that is a key element <strong>of</strong><br />

good clinical practice.<br />

What options should a doctor or<br />

health care pr<strong>of</strong>essional provide<br />

the patient with information about?<br />

This question raises the <strong>issue</strong> <strong>of</strong> what<br />

is ‘reasonable medical care’ or ‘a reasonable<br />

body <strong>of</strong> medical opinion’ (both<br />

terms are <strong>of</strong>ten used in disciplinary<br />

hearings). <strong>The</strong> concept becomes difficult<br />

to interpret when there are options<br />

available that may or may not be<br />

regarded as standard treatment in the<br />

context <strong>of</strong> the doctor’s practice. That<br />

problem became pressing in a NZ surgical<br />

case where a patient found out, via<br />

the Internet, about a radical approach<br />

to the treatment <strong>of</strong> brain tumours<br />

and took that option. Subsequently a<br />

complaint was made that he had not<br />

been told <strong>of</strong> the possibility as part <strong>of</strong><br />

his clinical management. <strong>The</strong> Health<br />

and Disability Commissioner’s opinion<br />

was that the advice given to the patient<br />

should have indicated the controversial<br />

possibility <strong>of</strong> more radical treatment<br />

than that which was <strong>of</strong>fered.<br />

It was held that the neurosurgeon should<br />

have taken the time to discuss the option<br />

<strong>of</strong> further surgery. Although it would<br />

not be reasonable to expect him to <strong>of</strong>fer<br />

to perform a procedure that he did not<br />

believe was a viable option, he needed<br />

to raise the option <strong>of</strong> further surgery<br />

(which was available elsewhere in <strong>New</strong><br />

<strong>Zealand</strong> and in Australia) and explain<br />

why he thought the risks outweighed any<br />

potential benefit. <strong>The</strong> surgeon was found<br />

in breach <strong>of</strong> Right 6(1)(b).<br />

<strong>The</strong> more radical surgical option was<br />

commented on by other neurosurgeons<br />

who wrote to the Commissioner in<br />

the following terms: ‘whether or not a<br />

doubtful procedure should be advised<br />

to an anxious patient who will clutch<br />

at any straw is indeed arguable’; ‘Dr [X]<br />

gave advice to the patient and his family<br />

in keeping with standard… opinion’; ‘it<br />

is difficult to see why a surgeon should<br />

apologise for a management plan that<br />

was correct.’ <strong>The</strong>se remarks express what<br />

many feel is sound and sensible when<br />

doctors are giving recommendations to<br />

patients about treatments. Nevertheless,<br />

the finding is in keeping with the<br />

Medical Council recommendation that<br />

a patient is entitled to know how the<br />

advice s/he has received compares with<br />

a range <strong>of</strong> clinical opinion in the area<br />

concerned. This is probably sound advice<br />

also in the light <strong>of</strong> the controversies<br />

surrounding complementary and alternative<br />

medicines (CAM) and ‘fringe’ or<br />

‘natural’ therapies.<br />

Should patients be encouraged<br />

to do their own homework?<br />

<strong>The</strong> ethical response to this question<br />

follows from the arguments above. In<br />

general, a patient should be encouraged<br />

to be an active participant in the<br />

problem-solving partnership that is a<br />

clinical relationship. In that context, a<br />

negotiated mix <strong>of</strong> spontaneous disclosure<br />

(conveying a more or less standard<br />

medical opinion about the patient’s<br />

problem) and a responsive disclosure<br />

(about matters raised by the patient)<br />

is likely to be the best that a wellintentioned<br />

doctor can do. <strong>The</strong> scope <strong>of</strong><br />

information that gets into that conversation<br />

is potentially broad but should<br />

have the effect <strong>of</strong> helping the patient<br />

find his/her way around in the strange<br />

land that is Clinicum 11 with its <strong>of</strong>ten<br />

poorly understood hazards and variably<br />

well-understood therapeutic responses<br />

to those hazards and where a great deal<br />

<strong>of</strong> the guidance that one gets in the<br />

normal course <strong>of</strong> practice is both interested<br />

and promotional.<br />

PSA screening reply<br />

In his Back to Back argument in favour <strong>of</strong> PSA screening,<br />

Robin Smart claims that PSA screening performs<br />

well compared to other screening programmes. 1 He gives a<br />

number needed to screen to save one life <strong>of</strong> 80, and number<br />

needed to treat to save one life <strong>of</strong> two to five. <strong>The</strong> source<br />

for these figures is not given, but they are very different<br />

from the preliminary estimates from the ERSPC study<br />

(which he quotes elsewhere) which found the number<br />

needed to screen over nine years to prevent one death was<br />

1410 and that the number needed to treat to prevent one<br />

death was 48. 2<br />

If men are to make an informed decision about whether<br />

to have a PSA test, then it is important that they are<br />

provided with the best estimates <strong>of</strong> the potential benefits<br />

and harms <strong>of</strong> the test. Smart’s figures give a misleadingly<br />

optimistic impression.<br />

Cardiovascular disease risk pr<strong>of</strong>ile tools and <strong>New</strong><br />

<strong>Zealand</strong>—absolutely the best way forward<br />

I<br />

n December 2009, the Journal <strong>of</strong> Primary Health Care published<br />

a non–peer reviewed essay about the use <strong>of</strong> cardiovascular<br />

disease (CVD) risk pr<strong>of</strong>ile tools in <strong>New</strong> <strong>Zealand</strong>. 1 <strong>The</strong><br />

authors <strong>of</strong> this essay, Boland and Moriarty, used a crosssection<br />

analysis undertaken by our research group (Bannink<br />

et al. 2006) 2 and an outdated systematic review (Brindle et al.<br />

2006) 3 to argue against the use <strong>of</strong> CVD risk pr<strong>of</strong>ile tools. As<br />

co-authors <strong>of</strong> the Bannink et al. paper we would appreciate the<br />

right <strong>of</strong> response.<br />

Boland and Moriarty are correct that our paper described<br />

the CVD risk factor status <strong>of</strong> the first 18 000 patients pr<strong>of</strong>iled<br />

in routine general practice in <strong>New</strong> <strong>Zealand</strong> using the PRE-<br />

DICT-CVD tool. <strong>The</strong>y also correctly stated that the PREDICT<br />

decision support system is based <strong>entire</strong>ly on evidence-based<br />

guidelines—the updated PREDICT CVD-Diabetes containing<br />

recommendations from the <strong>New</strong> <strong>Zealand</strong> Guidelines for CVD<br />

Risk Assessment and Management and the Management <strong>of</strong><br />

Type 2 Diabetes.<br />

However, the authors <strong>of</strong> the essay inappropriately criticise<br />

this paper as not being able to show evidence <strong>of</strong> effectiveness<br />

<strong>of</strong> CVD risk pr<strong>of</strong>ile tools. <strong>The</strong> Bannink paper was simply a<br />

cross-sectional analysis <strong>of</strong> risk factor pr<strong>of</strong>iles generated opportunistically<br />

in general practice. <strong>The</strong> purpose <strong>of</strong> this first paper<br />

by the PREDICT investigators was to describe the baseline<br />

characteristics <strong>of</strong> a cohort to be used to generate new risk prediction<br />

tools and to demonstrate how a cohort study could be<br />

undertaken in routine primary care practice using a web-based<br />

clinical decision support system (CDSS). This paper never was<br />

nor ever could be a study <strong>of</strong> effectiveness <strong>of</strong> decision support<br />

tools, nor would ever be included in a systematic review <strong>of</strong><br />

the impact <strong>of</strong> CVD risk pr<strong>of</strong>ile tools. It represented the first<br />

stage <strong>of</strong> a large <strong>New</strong> <strong>Zealand</strong> cohort study, the most appropriate<br />

study design for generating risk prediction equations.<br />

<strong>The</strong> Framingham equation used in <strong>New</strong> <strong>Zealand</strong> CVD<br />

risk assessment and management guidelines 4 has long been<br />

acknowledged as having deficiencies leading to over-prediction<br />

<strong>of</strong> risk in low risk populations and under-prediction <strong>of</strong> risk<br />

in high risk populations. 3 In the six years since the publication<br />

<strong>of</strong> Bannink et al., <strong>New</strong> <strong>Zealand</strong> GPs and practice nurses<br />

have produced a cohort <strong>of</strong> over 120 000 participants using the<br />

PREDICT decision support system. By linking the risk pr<strong>of</strong>iles<br />

in this cohort to hospitalisations and deaths, it will be possible<br />

to develop up-to-date risk prediction equations relevant<br />

for all <strong>New</strong> <strong>Zealand</strong>ers and for specific high risk population<br />

subgroups such as those <strong>of</strong> Maori, Pacific and South Asian<br />

ethnicities. Boland and Moriarty raise concerns about possible<br />

missing ethnicity data. As ethnicity is an integral variable in<br />

<strong>New</strong> <strong>Zealand</strong> risk prediction algorithms, it is not possible to<br />

get a risk prediction score using PREDICT without having<br />

complete data entry. Indeed, there is no missing risk assessment<br />

data on anyone in the PREDICT cohort.<br />

LETTERS TO THE EDITOR<br />

<strong>The</strong> authors develop a debate against the effectiveness <strong>of</strong><br />

CVD risk pr<strong>of</strong>ile tools citing the systematic review by Brindle<br />

et al. published in 2006. <strong>The</strong>y state that ‘…this review found<br />

no conclusive evidence that the use <strong>of</strong> CVD risk pr<strong>of</strong>ile tools<br />

significantly improves patient care.’<br />

<strong>The</strong> review, now out-dated, found that ‘four randomised<br />

controlled trials confined to people with hypertension or<br />

diabetes found no strong evidence that a cardiovascular risk assessment<br />

performed by a clinician improves health outcomes.’<br />

<strong>The</strong> four randomised controlled trials investigated the impact<br />

<strong>of</strong> giving patients a CVD risk score. CVD risk assessment<br />

and management requires a long-term committment to our<br />

patients. It is well-known that one-<strong>of</strong>f advice rarely leads to<br />

persisting changes in patient behaviour. So it is not surprising<br />

that providing a CVD risk assessment at one point in time did<br />

not change patient health outcomes. Furthermore, two <strong>of</strong> the<br />

trials had a CDSS, the others did not. In the two trials using a<br />

CDSS there was very poor uptake <strong>of</strong> the systems by practitioners,<br />

and one was not integrated with the patient’s electronic<br />

medical record—one <strong>of</strong> the most important factors shown to<br />

support uptake and use <strong>of</strong> CDSSs. 5 PREDICT is integrated<br />

into practitioners’ patient management systems, provides decision<br />

support at the time and location <strong>of</strong> decision-making and<br />

generates a comprehensive, personalised set <strong>of</strong> evidence-based<br />

management recommendations, not just a risk score. <strong>The</strong> latter<br />

functionalities have also been shown to be critical independent<br />

predictors <strong>of</strong> improved clinical practice. 5<br />

Furthermore, Boland and Moriarty did not base their argument<br />

on up-to-date evidence <strong>of</strong> the effectiveness <strong>of</strong> CDSS for<br />

CVD. A more relevant systematic review was conducted in<br />

2008. 6 This review identified 42 randomised controlled trials<br />

<strong>of</strong> computerised systems for assessment and management <strong>of</strong><br />

CVD risk or risk factors in primary care. All <strong>of</strong> the older trials<br />

including non–user friendly, non-integrated systems were<br />

included. <strong>The</strong> evidence for the impact <strong>of</strong> CDSS in general has<br />

been moderately favourable in terms <strong>of</strong> improving desired<br />

practice. Of the randomised trials <strong>of</strong> CDSS for assessing or<br />

managing CVD risk, about two-thirds reported improvements<br />

in provider processes (such as improved documentation, increase<br />

in recommended examinations, investigations, providing<br />

advice or management plans) and two-fifths reported some<br />

improvements in intermediate patient outcomes (reduction<br />

in CVD risk, BP or cholesterol levels). Most importantly, no<br />

harms were reported.<br />

We believe that CVD risk pr<strong>of</strong>ile tools incorporated within<br />

general practice management systems have significant potential<br />

to improve the quality <strong>of</strong> patient care in <strong>New</strong> <strong>Zealand</strong>. <strong>The</strong><br />

unique advantage <strong>of</strong>fered by the PREDICT system is its ability<br />

to also provide real-time aggregated reports to individual<br />

practices on their patient care and to generate a cohort study<br />

for developing new risk prediction tools that are based on <strong>New</strong><br />

<strong>Zealand</strong> populations. Moreover we have now integrated into<br />

PREDICT the ‘Your Heart Forecast’ (www.yourheartforecast.<br />

co.nz) tool that we developed in collaboration with the National<br />

Heart Foundation to support and improve risk communication.<br />

This has been well-received by clinical users. Evaluation<br />

to determine whether Your Heart Forecast faciltates patient<br />

understanding <strong>of</strong> a CVD risk score and supports behaviour<br />

change is underway.<br />

We challenge Boland and Moriarty to find both more<br />

appropriate and more up-to-date evidence to support their<br />

arguments.<br />

BOOK REVIEW<br />

Interpreting in <strong>New</strong> <strong>Zealand</strong>, the pathway<br />

forward<br />

by Diana Clark and Caroline McGrath<br />

Reviewed by Ben Gray, GP <strong>New</strong>town Union Health Service.<br />

<strong>General</strong> practitioners (GPs) face many risks in<br />

the course <strong>of</strong> an average day. <strong>The</strong>se cluster<br />

alarmingly when a doctor manages a patient<br />

who speaks little or no English. As well as risks<br />

to diagnosis, discussion and treatment, impaired<br />

communication means there are shadows over informed<br />

consent, disclosure <strong>of</strong> previous history, and<br />

how to agree and implement a management plan.<br />

<strong>The</strong> RNZCGP’s practice accreditation document<br />

Aiming For Excellence is almost silent on how to<br />

deal with this problem. Few <strong>of</strong> us have thought<br />

about pr<strong>of</strong>essional and ethical <strong>issue</strong>s as they<br />

might apply to interpreters. <strong>The</strong>y are probably<br />

the only mainstream health pr<strong>of</strong>essional without<br />

an agreed training programme, agreed pr<strong>of</strong>essional<br />

ethics or requirement for registration and<br />

monitoring <strong>of</strong> quality.<br />

<strong>The</strong> Office <strong>of</strong> Ethnic Affairs has produced a book<br />

as a way <strong>of</strong> informing and encouraging debate on<br />

how <strong>New</strong> <strong>Zealand</strong> (NZ) addresses these important<br />

<strong>issue</strong>s and goes forward as a multilingual country.<br />

This book sets out in more than 20 contributions<br />

from NZ and overseas, expertise, insights and<br />

experience in interpreting and related fields. <strong>The</strong><br />

submissions range from the anecdotal (should an<br />

interpreter tell a nurse the patient is a former doctor<br />

from Russia who feels her ear is not being syringed<br />

in the right way?) to ethics, both here and overseas,<br />

to a useful chart setting out the difference between<br />

the activities undertaken by the interpreter and the<br />

translator. <strong>The</strong>re are contributions from educators,<br />

interpreting practitioners and from those with long<br />

experience in the deaf community.<br />

<strong>The</strong> book is not an academic text. It is more <strong>of</strong> a<br />

manual enabling someone who wanted to know<br />

about working with an interpreter to do so and to<br />

be aware <strong>of</strong> some <strong>of</strong> the fish hooks.<br />

Today NZ demographics almost guarantee GPs<br />

will have patients with limited English. Almost a<br />

quarter <strong>of</strong> residents were not born here. Though<br />

many speak English, others don’t. All are entitled<br />

to have access to the services <strong>of</strong>fered by GPs and<br />

management <strong>of</strong> health <strong>issue</strong>s will be a very important<br />

part <strong>of</strong> effective settlement for them all.<br />

In the past, children routinely have been used<br />

as bilingual helpers with no way <strong>of</strong> establishing<br />

the quality <strong>of</strong> their language knowledge nor the<br />

consistency or accuracy <strong>of</strong> their interpretations.<br />

Grim stories <strong>of</strong> serious consequences and misunderstandings<br />

abound, but it seemed there was no<br />

alternative.<br />

If you have felt bewildered, irritated or alarmed<br />

at the challenges and risks inherent in diagnosing<br />

and providing health care to someone who<br />

doesn’t speak English, then this book is for you.<br />

<strong>The</strong>re is a way forward if we can have accurate,<br />

confidential and cost-effective interpreting<br />

because this change will affect all <strong>of</strong> us as our<br />

practices become more multilingual.<br />

POLICY STATEMENT FOR AUTHORS<br />

Conflict <strong>of</strong> interest in peer-reviewed medical<br />

journals: <strong>The</strong> World Association <strong>of</strong> Medical Editors<br />

(WAME) position on a challenging problem<br />

Lorraine E Ferris 1 and Robert H Fletcher 2<br />

Conflict <strong>of</strong> interest in medical publishing<br />

exists when a participant’s private<br />

interests compete with his or her responsibilities<br />

to the scientific community, readers, and<br />

society. While conflict <strong>of</strong> interest is common,<br />

it reaches the level <strong>of</strong> concern when ‘a reasonable<br />

observer might wonder if the individual’s<br />

behavior or judgment was motivated by his or her<br />

competing interests’. 1 Having a competing interest<br />

does not, in itself, imply wrongdoing. But it<br />

can undermine the credibility <strong>of</strong> research results<br />

and damage public trust in medical journals.<br />

In recent years, the extent <strong>of</strong> conflict <strong>of</strong> interest<br />

in medical journal articles has been increasingly<br />

recognised. Medical journals and the popular<br />

media have published numerous examples <strong>of</strong><br />

competing interests that seemed to have biased<br />

published reports. 2,3,4 Organisations have<br />

expressed concern for the effects <strong>of</strong> conflicts <strong>of</strong><br />

interest on research, 5 publication, 1,6,7 teaching 8<br />

and continuing medical and nursing education. 9<br />

<strong>The</strong> World Association <strong>of</strong> Medical Editors<br />

(WAME) is one <strong>of</strong> the institutions engaged<br />

in this discussion. WAME was established in<br />

1995 10,11 to facilitate worldwide cooperation and<br />

communication among editors <strong>of</strong> peer-reviewed<br />

journals, improve editorial standards, and<br />

promote pr<strong>of</strong>essionalism in medical editing. 12<br />

Membership in WAME is open to all editors <strong>of</strong><br />

peer-reviewed biomedical journals worldwide;<br />

small journals in resource-poor countries are wellrepresented.<br />

As <strong>of</strong> December 2009, WAME had<br />

1595 individual members representing 965 journals<br />

in 92 countries. WAME has broad participation<br />

as there are no dues and WAME activities are<br />

largely carried out through the member list serve<br />

and the member password-protected website.<br />

In March 2009, WAME released an updated policy<br />

statement, Conflict <strong>of</strong> interest in peer-reviewed medical<br />

journals. 1 It details the <strong>issue</strong>s WAME believes<br />

journals should address when establishing their<br />

own policies for conflict <strong>of</strong> interest. <strong>The</strong> editors<br />

<strong>of</strong> this journal thought that the <strong>issue</strong>s were important<br />

enough to share with its readers. A summary<br />

<strong>of</strong> the statement is presented in Table 1 and the<br />

full statement 1 can be found on WAME’s website. 12<br />

How does this statement differ from<br />

earlier conflict-<strong>of</strong>-interest statements?<br />

First, WAME expands the scope <strong>of</strong> competing<br />

interests. Other statements have been concerned<br />

almost exclusively with conflicts <strong>of</strong> interest related<br />

to financial ties to industry—companies that<br />

sell health care products. <strong>The</strong> assumption is that<br />

financial incentives are especially powerful and<br />

are not readily recognised without special efforts<br />

to make them apparent. WAME has extended the<br />

concept <strong>of</strong> financial conflict <strong>of</strong> interest to include<br />

the effects <strong>of</strong> clinical income. For example,<br />

physicians who earn their livelihood by reading<br />

mammograms or performing colonoscopies may<br />

be biased in favour <strong>of</strong> these technologies. WAME<br />

has also included non-financial conflicts <strong>of</strong> interest<br />

(or the appearance <strong>of</strong> one) related to scholarly<br />

commitment: ‘intellectual passion’, (the tendency<br />

to favour positions that one has already espoused<br />

or perhaps even established); personal relationships<br />

(the tendency to judge the works <strong>of</strong> friends/<br />

colleagues or competitors/foes differently because<br />

<strong>of</strong> the relationship); political or religious beliefs<br />

(the tendency to favour or reject positions because<br />

it affirms or challenges one’s political or religious<br />

beliefs); and institutional affiliations (the<br />

tendency to favour or reject results <strong>of</strong> research<br />

because <strong>of</strong> one’s institutional affiliations).<br />

POLICY STATEMENT FOR AUTHORS<br />

Second, WAME did not prescribe a universal<br />

standard for when meaningful conflict <strong>of</strong> interest<br />

exists. Rather, it defined and recommended elements<br />

<strong>of</strong> conflict <strong>of</strong> interest policies and encouraged<br />

journals to establish their own standards.<br />

WAME left operational definitions and standards<br />

on the basic <strong>issue</strong>s to member journals, recognising<br />

that journals exist in very different contexts<br />

across the globe, standards for conflict <strong>of</strong> interest<br />

are evolving, and some journals already have<br />

well-established policies and standards. WAME<br />

does not presume to judge which conflicts require<br />

action and what the appropriate action may be,<br />

although its policy does <strong>of</strong>fer factors to consider.<br />

1 Obviously, excessive concern for these and<br />

more comprehensive lists <strong>of</strong> possible competing<br />

interests could paralyse the peer review and<br />

publication process and is not feasible. Editors<br />

must make judgments as to the strength <strong>of</strong> the<br />

conflict, but to do so must have uncensored<br />

information. Similarly, readers need transparency<br />

about conflicts, and therefore editors should<br />

publish with every article all relevant author<br />

disclosures. 1<br />

Third, WAME confirms the seriousness <strong>of</strong><br />

failure to disclose conflict <strong>of</strong> interest by indicating<br />

that editors have a responsibility for investigating<br />

and, if relevant, acting, if competing<br />

interests surface after a manuscript is submitted<br />

Element Key aspects Comments<br />

scope<br />

2. Types <strong>of</strong><br />

competing interests<br />

3. Declaring conflicts<br />

<strong>of</strong> interest<br />

4. Managing conflicts<br />

<strong>of</strong> interest<br />

A clear definition the journal uses as to what<br />

is conflict <strong>of</strong> interest and who is captured in<br />

the definition.<br />

A clear statement <strong>of</strong> examples <strong>of</strong> the types<br />

<strong>of</strong> competing interests (and their definitions)<br />

the journal says must be declared. Should<br />

include the following as examples, but there<br />

could be others:<br />

(a) Financial ties<br />

(b) Academic commitments<br />

(c) Personal relationships<br />

(d) Political or religious beliefs<br />

(e) Institutional affiliations<br />

Clear statements on:<br />

(a) what is to be declared, when and to<br />

whom;<br />

(b) format for declaration;<br />

(c) a journal’s role in asking additional<br />

questions or seeking clarification about<br />

disclosures; and<br />

(d) consequences for failing to disclose<br />

before or after publication.<br />

A clear statement on how conflict <strong>of</strong> interest<br />

will be managed by the journal, including the<br />

position that all relevant conflict <strong>of</strong> interest<br />

disclosures (or the declaration <strong>of</strong> no conflict<br />

<strong>of</strong> interest) will be published with the article<br />

and clarity about what conflict <strong>of</strong> interest<br />

situations will result in a manuscript not<br />

being considered.<br />

Sample definition: Conflict <strong>of</strong> interest<br />

exists when a participant in the publication<br />

process (author, peer reviewer or editor)<br />

has a competing interest that could unduly<br />

influence (or be reasonably seen to do so)<br />

his or her responsibilities in the publication<br />

process (submission <strong>of</strong> manuscripts,<br />

peer review, editorial decisions, and<br />

communication between authors, reviewers<br />

and editors).<br />

<strong>The</strong>re is a need to consider a wide range<br />

<strong>of</strong> competing interests (and a recognition<br />

that they can coexist) which the individual<br />

assesses as to whether they unduly influence<br />

(or be reasonably seen to do so) his or her<br />

responsibilities in the publication process.<br />

Examples and definitions <strong>of</strong> what competing<br />

interests should be declared need to be<br />

articulated with journals moving beyond just<br />

financial conflict <strong>of</strong> interest.<br />

Journals rely on disclosure about the facts<br />

because routine monitoring or investigation<br />

is not possible. This creates a particular<br />

onus on the declarer to report carefully and<br />

comprehensively. It also means that journals<br />

should ask about conflict <strong>of</strong> interest in such<br />

a way that there will be a high likelihood <strong>of</strong><br />

reporting relevant conflict <strong>of</strong> interest.<br />

Journals use various rules about how they<br />

will deal with conflict <strong>of</strong> interest and conflict<br />

<strong>of</strong> interest disclosures and these need to<br />

be made known to all those involved in the<br />

publication process.<br />

POLICY STATEMENT FOR AUTHORS<br />

or published. <strong>The</strong> intent is that allegations <strong>of</strong> failure<br />

to declare conflicts <strong>of</strong> interest must be taken<br />

seriously by journals.<br />

Finally, WAME has addressed in a single statement<br />

the conflicts <strong>of</strong> interest threatening all<br />

participants in the research and publication continuum,<br />

including authors, peer reviewers, and<br />

editors. Conflicts between editors and journal<br />

owners, which might affect both the accuracy <strong>of</strong><br />

articles and the credibility <strong>of</strong> journals, have been<br />

addressed in another WAME policy statement. 13<br />

What can be done about conflicts<br />

<strong>of</strong> interest in medical journals?<br />

Conflicts <strong>of</strong> interest cannot be eliminated altogether,<br />

but it can be managed so that it has the<br />

smallest possible effects on journal content and<br />

credibility. <strong>The</strong> backbone <strong>of</strong> managing conflicts<br />

<strong>of</strong> interest is full written disclosure; without it,<br />

nothing else is possible. Currently, authors may<br />

not reveal all <strong>of</strong> their competing interests and,<br />

even if they do, journals too <strong>of</strong>ten do not publish<br />

them, 14 so there is plenty <strong>of</strong> room for improvement.<br />

Even so, disclosure alone is an imperfect<br />

remedy; editors still must determine whether a<br />

conflict has sufficient potential to impair an individual’s<br />

objectivity such that the article should<br />

not be published. Even more work may be needed<br />

on reviewers’ and editors competing interests,<br />

given their critical role as gatekeepers for the<br />

medical literature.<br />

No statement will solve the conflict <strong>of</strong> interest<br />

problem, nor will it ever be solved altogether. As<br />

understanding <strong>of</strong> the problem and its management<br />

evolves, journals should be given latitude<br />

to establish their own standards, matching their<br />

policies to the best standards <strong>of</strong> their discipline<br />

and culture. WAME believes journals should<br />

make these policies readily accessible to everyone.<br />

All <strong>of</strong> us—editors, authors, reviewers, and<br />

readers—should be paying more attention to<br />

conflicts <strong>of</strong> interest than we have been. We hope<br />

this statement serves that purpose.<br />

This editorial may appear in other medical and<br />

biomedical journals whose editors are members <strong>of</strong><br />

the World Association <strong>of</strong> Medical Editors (WAME).<br />

to 2003 using data from the Dunedin<br />

RNZCGP Research Unit database <strong>of</strong><br />

54 years who consulted a doctor in<br />

2000–2003 in practices supplying electronic<br />

as calculated by the Framingham-based<br />

risk equation could only be estimated<br />

for one-third <strong>of</strong> the study population<br />

due to missing risk factor information.<br />

<strong>The</strong> treatment <strong>of</strong> all patient groups with<br />

a five-year cardiovascular risk <strong>of</strong> >10%<br />

increased by about 4% per year, and by<br />

3% per year in the five to 10% cardiovascular<br />

<strong>The</strong> aim <strong>of</strong> this study was to determine<br />

pharmacists’ views on these roles and<br />

the need for accreditation. Findings from<br />

a national postal survey suggest the majority<br />

<strong>of</strong> pharmacists believe they should<br />

continue to undertake traditional clinical<br />

and technical roles. Less than one-third<br />

suggested accreditation for these roles.<br />

<strong>The</strong>re was a positive but more tempered<br />

view regarding the uptake <strong>of</strong> enhanced<br />

<strong>of</strong> a need for accreditation suggesting<br />

a cautious optimism about adopting<br />

Describing the organisational<br />

culture <strong>of</strong> a selection <strong>of</strong><br />

community pharmacies<br />

This paper outlines the use <strong>of</strong> a predominantly<br />

interpretative mixed methods<br />

technique known as concept mapping<br />

to develop a map which pictorially<br />

represents dimensions <strong>of</strong> organisational<br />

culture. Concept mapping involves the<br />

integration <strong>of</strong> brainstorming techniques<br />

to develop culture statements, along<br />

with robust statistical processes. Eight<br />

cultural dimensions were identified:<br />

leadership and staff management; valuing<br />

each other and the team; free thinking,<br />

fun and open to challenge; trusted<br />

behaviour; customer relations; focus on<br />

external integration; providing systematic<br />

advice and embracing innovation.<br />

<strong>The</strong>se dimensions assist in understanding<br />

factors that influence effectiveness<br />

within community pharmacy.<br />

How useful are clinical priority<br />

assessment tools?<br />

<strong>The</strong> original aim <strong>of</strong> this research was to<br />

study the use <strong>of</strong> clinical priority assessment<br />

criteria (CPAC) tools. However, in<br />

a sample <strong>of</strong> 47 videotaped consultations<br />

with 15 different surgeons, CPAC tools<br />

were never explicitly used. <strong>The</strong> research<br />

therefore shifted to an investigation <strong>of</strong><br />

interactional factors that might preclude<br />

the use <strong>of</strong> such tools. Our analysis<br />

suggested that decision-making about<br />

operative thresholds is an interactionally<br />

complex matter that does not lend itself<br />

to the rigid following <strong>of</strong> a protocol. It<br />

should be acknowledged that diagnosis<br />

and planning <strong>of</strong> care constitute different<br />

interactional activities to prioritisation<br />

on a waiting list.<br />

Pharmacists not ready for<br />

increased clinical roles<br />

This paper reports on a 2002 survey <strong>of</strong><br />

general practitioners and community<br />

pharmacists, exploring the perceptions<br />

<strong>of</strong> the role <strong>of</strong> the community pharmacist.<br />

<strong>The</strong>re were significant differences<br />

in the perceptions <strong>of</strong> the role <strong>of</strong><br />

community pharmacists, with general<br />

acceptance <strong>of</strong> technical roles (dispensing,<br />

checking accuracy, counselling on ADRs<br />

and monitoring for compliance) but<br />

less acceptance <strong>of</strong> more clinical patient<br />

care roles. <strong>The</strong> barriers to increased<br />

clinical roles for community pharmacists<br />

included a perceived lack <strong>of</strong> mandate,<br />

legitimacy, adequacy and effectiveness<br />

<strong>of</strong> the roles. <strong>The</strong>re also appeared to be a<br />

lack <strong>of</strong> readiness to change for community<br />

pharmacists.<br />

Investigating prescription<br />

interventions conducted<br />

by pharmacists<br />

This study investigated the time spent<br />

and the types <strong>of</strong> interventions pharmacists<br />

in Dunedin perform when<br />

dispensing prescription medications.<br />

Interventions related to generic substitution<br />

and legal errors and omissions were<br />

responsible for 50% <strong>of</strong> their time spent.<br />

This could be reduced significantly by<br />

prescribing generically. <strong>The</strong> remaining<br />

50% <strong>of</strong> time spent was on clinical<br />

interventions, however these occurred<br />

at a much lower rate. <strong>The</strong> time spent on<br />

bureaucratic <strong>issue</strong>s may be seen as a significant<br />

barrier for pharmacists providing<br />

clinical services to patients.<br />

Women may be missing out<br />

on preventive drugs<br />

Among 1089 women (40–79 years)<br />

recruited through 17 general practices<br />

to a lifestyle study in the Wellington<br />

region in 2005–2007, 109 (10%) had<br />

a five-year cardiovascular (CVD) risk<br />

>15%. Of these women, only 36% were<br />

taking aspirin, 55% were on blood<br />

pressure–lowering medication, 45%<br />

were taking lipid-lowering medication<br />

and only 17% were taking all three<br />

CVD guidelines–recommended medications.<br />

Our coverage <strong>of</strong> CVD preventive<br />

medications for high-risk women may<br />

be lower than ideal.<br />

Including type 2 diabetes in<br />

cardiovascular risk equations<br />

A new cardiovascular risk equation was<br />

derived from routinely-collected data<br />

on 36 127 patients with type 2 diabetes<br />

assessed through the primary care Get<br />

Checked programme between 2000 and<br />

2006 in <strong>New</strong> <strong>Zealand</strong>. <strong>New</strong> cardiovascular<br />

events or deaths were recorded<br />

2000–2008. Testing the new equation<br />

on 12 626 patients from a geographically-different<br />

area over the same time<br />

showed that the new equation was more<br />

accurate than the currently used equation<br />

for people with diabetes, especially<br />

for Maori, Pacific and Indian populations<br />

and those with poorly controlled diabetes<br />

or renal impairment. <strong>The</strong> currently<br />

used equation <strong>of</strong>ten underestimates<br />

risk for these groups. <strong>The</strong> new equation<br />

could be incorporated into existing risk<br />

assessment tools.<br />

Asking about help is helpful<br />

<strong>The</strong> CHAT (Case-finding and Help Assessment<br />

Tool) is a short validated and<br />

self-administered questionnaire which<br />

detects lifestyle (inactivity, tobacco use,<br />

alcohol and other drug misuse, problem<br />

gambling, abuse, and anger problems)<br />

and mental health <strong>issue</strong>s (depression and<br />

anxiety) in adult primary health care<br />

patients. <strong>The</strong> question asking whether<br />

patients want help (either during this<br />

consultation or later) for each item increases<br />

specificity without compromising<br />

sensitivity and reduces false positives,<br />

allows patients with comorbidities to<br />

prioritise <strong>issue</strong>s they wish to address, indicate<br />

their readiness to change, promote<br />

self-determination, and gives the GP an<br />

indication <strong>of</strong> which topics to pursue.<br />

about the journal <strong>of</strong> primary health care<br />

<strong>The</strong> Journal <strong>of</strong> Primary Health Care<br />

(JPHC) is a peer-reviewed journal<br />

which has replaced the <strong>New</strong> <strong>Zealand</strong><br />

Family Physician. It is a interdisciplinary<br />

publication aimed at moving research into<br />

primary health care practice and practice into<br />

research. This includes the fields <strong>of</strong> family<br />

practice, primary health care nursing and<br />

community pharmacy as well as areas such<br />

as health care delivery, health promotion,<br />

epidemiology, public health and medical<br />

sociology <strong>of</strong> interest to a primary health care<br />

provider audience.<br />

<strong>The</strong> journal publishes peer-reviewed quantitative<br />

and qualitative original research,<br />

systematic reviews, papers on improving performance<br />

and short reports that are relevant<br />

to its primary health care practitioners. For<br />

the aim, scope, instructions to authors and<br />

templates for publications see www.rnzcgp.<br />

org.nz/journal-<strong>of</strong>-primary-health-care/.<br />

JPHC acts as a knowledge refinery to provide<br />

busy practitioners with up-to-date knowledge<br />

about the latest evidence and best practice.<br />

Continuing pr<strong>of</strong>essional development<br />

includes pithy summaries <strong>of</strong> the latest evidence<br />

such as Cochrane Corner, a String <strong>of</strong><br />

PEARLS (Practical Evidence About Real Life<br />

Situations) and Charms & Harms (evidence <strong>of</strong><br />

effectiveness and safety <strong>of</strong> complementary<br />

and alternative medicines). JPHC includes<br />

Poumanu (treasures <strong>of</strong> Maori wisdom) and<br />

Gems <strong>of</strong> NZ Primary Health Care Research<br />

published at home and internationally.<br />

Evidence can help inform best practice. However<br />

sometimes there is no evidence available<br />

or applicable for a specific patient with his<br />

or her own set <strong>of</strong> conditions, capabilities,<br />

beliefs, expectations and social circumstances.<br />

Evidence needs to be placed in context.<br />

<strong>General</strong> practice is an art as well as a science.<br />

Quality <strong>of</strong> care lies also with the nature <strong>of</strong> the<br />

clinical relationship, with communication and<br />

with truly informed decision-making. JPHC<br />

publishes viewpoints, commentaries and reflections<br />

that explore areas <strong>of</strong> uncertainty on<br />

aspects <strong>of</strong> care for which there is no one right<br />

answer. Debate is stimulated by the Back to<br />

Back section where two pr<strong>of</strong>essionals present<br />

their opposing views on a topic. <strong>The</strong>re is a<br />

regular Ethics column. Letters to the Editor<br />

are welcomed.<br />
