Hospitalizations, nursing home admissions, and deaths attributable to diabetes.

Abstract

To estimate all-cause hospitalizations, nursing home admissions, and deaths attributable to diabetes using a new methodology based on longitudinal data for a representative sample of older U.S. adults. A simulation model, based on data from the National Health and Nutrition Examination Survey (NHANES) I Epidemiologic Followup Study, was used to represent the natural history of diabetes and control for a variety of baseline risk factors. The model was applied to 6,265 NHANES III adults aged 45-74 years. The prevalence of risk factors in NHANES III, fielded in 1988-1994, better represents today's adults. For all NHANES III adults aged 45-74 years, a diagnosis of diabetes accounted for 8.6% of hospitalizations, 12.3% of nursing home admissions, and 10.3% of deaths in 1988-1994. For people with diabetes, diabetes alone was responsible for 43.4% of hospitalizations, 52.1% of nursing home admissions, and 47% of deaths. Adjusting for related cardiovascular conditions, which may provide more accurate estimates of attributable risks for people with diabetes, increased these estimates to 51.4, 57.1, and 56.8%, respectively. Risks of institutionalization and death attributable to diabetes are large. Efforts to translate recent trials of primary prevention into practice and continued efforts to prevent complications of diabetes could have a substantial impact on hospitalizations, nursing home admissions, and deaths and their societal costs.
