Hospitalization for general medical conditions among diabetic patients in Israel.

BACKGROUND Diabetes mellitus is a serious, costly and growing public health problem. Very few studies have been published on the economic impact of diabetes in Israel. OBJECTIVE To estimate health fund expenditures and rates of hospitalization for general conditions among the diabetic population in Israel. METHODS The total number of hospitalizations in Israel in 1998 of beneficiaries of the General Sick Fund (Kupat Holim Clalit) was obtained from its bureau of statistics. The diabetic and general populations were compared for age and gender distribution, days of hospitalization and cost of hospitalization. All hospitals in Israel were included. RESULTS There were 618,317 general admissions for a total of 3,005,288 hospitalization days. The diabetic population accounted for 11.5% of all admissions and 13.7% of all hospitalization days. Analysis by age revealed that diabetic patients over age 45 represented 18.3% of all admissions and 17.5% of all hospitalization days. The average stay in hospital was 4.8 days per patient for the general population and 5.3 days for diabetic patients. The overall hospital expenditure of the GSF for general medical conditions among diabetic patients in 1998 was estimated at US $173,455,790, of which 57% accounted for the daily hospitalization cost. Of the total hospital expenditures for that year, 13.3% was allocated to patients with diabetes of whom 96.4% were over 45 years old. No significant difference was found between males and females. CONCLUSION Hospital expenditures for diabetic people increase with patient age and represent one-fifth of the total health insurance expenditure for the middle-aged and elderly population.
