OBJECTIVE--To assess and compare excess costs of care and production losses
because of morbidity in diabetic patients and the general population of a
Swedish community. RESEARCH DESIGN AND METHODS--Costs of production losses
were calculated from medical and social insurance records on sickness
benefit days (short-term illness) and premature retirement (permanent
disability) in people with diabetes and in the entire population of the
community (a municipality comprising a town and rural surroundings, with
28,000 inhabitants). Care costs included those of consultations and
inpatient care, as well as costs of insulin, oral antidiabetic medications,
other drugs, test material, and treatment devices, and they were obtained
from patient records, the health care administration, and the statistics of
community pharmacy sales. RESULTS--Of the diabetic patients < 65 years
of age, above which both diabetic and nondiabetic people get retirement
pension, and sickness benefits cease, 62% of those on insulin treatment in
each gender had insulin-dependent diabetes mellitus (IDDM). All
insulin-treated non-insulin-dependent diabetes mellitus (NIDDM) patients
were > 40 years of age. Both the insulin-treated and the
non-insulin-treated diabetic patients were prematurely retired twice as
often as the average population and had twice as many inpatient days. The
insulin-treated subjects also had twice as many sickness benefit days. The
excess costs of production losses as a result of morbidity in people with
diabetes were about $7,000 per individual and year. The corresponding
excess costs of inpatient care were $800. The therapeutic expenditures for
control of diabetes were about $600 per individual and year. If converted
to U.S. conditions, the costs of lost production as a result of excess
morbidity (< 65 years of age) would be $12 billion and $9 billion for
people with insulin-treated and non-insulin-treated diabetes, respectively.
CONCLUSIONS--If improved metabolic control by intensified treatment would
reduce excess morbidity in both IDDM and NIDDM, the predominant costs of
production losses imply that intensified antidiabetic treatment might save
costs.
