The indirect costs of morbidity in type II diabetic patients

In an attempt to obtain an appropriate estimate of the excess costs of production losses arising from morbidity in patients with diabetes, we compared the number of sick days and permanently disabled individuals in a diabetic population and the corresponding general population. These comparisons show that the rate of premature retirement for both insulin-dependent diabetes mellitus (IDDM, type I diabetes) or non-insulin-dependent diabetes mellitus (NIDDM, type II diabetes) patients was twice that of the average population. Insulin-treated subjects also had twice as many sickness benefit days. The excess costs of production losses as a result of morbidity in people aged 20 to 64 years with type II diabetes were about $US7000 per individual and year. Most of these excess costs were attributed to permanent disability in the 40- to 64-year age groups.
