Hospital discharge rates for nontraumatic lower extremity amputation by diabetes status--United States, 1997

Abstract

Lower extremity amputation (LEA) is a costly and disabling procedure that disproportionately affects persons with diabetes. One of the national health objectives for 2000 was to reduce the LEA rate from a 1991 baseline of approximately eight per 1,000 persons with diabetes to a target of approximately five per 1,000 persons with diabetes. Review of 1996 data indicated an LEA rate of approximately 11. To estimate the national rates of hospital discharges for LEA among persons with and without diabetes and to assess the excess risk for LEA among persons with diabetes, CDC and the Agency for Healthcare Research and Quality (AHRQ) analyzed data from the 1997 Nationwide Inpatient Sample (NIS) and the 1997 National Health Interview Survey (NHIS). This report summarizes the findings of the analysis, which indicated that the age-adjusted rates of hospital discharges among persons with LEA who had diabetes were 28 times that of those without diabetes. This higher rate underscores the need to increase efforts to prevent risk factors (e.g., peripheral vascular disease, neuropathy, and infection) that result in LEA among persons with diabetes.
