of MSDs
Work and MSDs in Bulgaria
with these factors the number of MSDs experienced by Bulgarian workers could be reduced
significantly.
The effect that MSDs can have on individuals’ ability to work and the time they may require to
be absent from work means that MSDs have significant associated costs to the individual, their
family, the employer and the wider economy. Calculating the exact costs is not straightforward
(Lundkvist, Kastäng and Kobelt, 2008). Several factors need to be considered, and obtaining
accurate, reliable and consistent figures is almost impossible. However, existing figures on
the economic impact of MSDs based on conservative approximations show that MSDs are a
significant economic burden to Bulgaria.
To calculate the cost of MSDs (or any illness) the following factors must be estimated:
• Direct costs including medical expenditure, such as the cost of prevention, detection,
treatment, rehabilitation, long-term care and ongoing medical and private expenditure.
They are often further separated into medical costs occurring in the health care sector
and non-medical costs occurring in other sectors (Lundkvist, Kastäng and Kobelt,
2008);
• Indirect costs including lost work output attributable to a reduced capacity for activity,
such as lost productivity, lost earnings, lost opportunities for family members, lost
earnings of family members and lost tax revenue;
• Intangible costs including psychosocial burden resulting in reduced quality of life, such
as job stress, economic stress, family stress and suffering (WHO, 2003).
These costs vary considerably depending on the condition, the severity of the symptoms and
whether these cause short or long term absence or disability. Moreover, they vary depending on
the particular methods used to calculate the costs. Some factors which affect the calculations
include the following:
• Severity of patient’s conditions;
• Mix of patient demographics in a study;
• Calculation method for productivity;
• Definitions of work disability;
• Treatment costs or outcomes due to treatments (the year costs were calculated which
is also a factor not least because treatment processes can change);
• Change in health care financing systems;
• Incidence or prevalence based estimates of costs.
