Decreasing incidence of major amputations in people with diabetes

Aims/hypothesis. To assess the results of the strategy used in avoiding major amputations in patients with diabetes mellitus. Methods. A retrospective study for the Years 1981 to 1995 in a central district hospital in Copenhagen with a catchment area population of about 178 000. Results. There were 463 major leg amputations and the incidence decreased from 27.2 to 6.9/100 000 population (minus 75%). The decrease in patients with Type I diabetes mellitus was from 10.0 to 4.1 (minus 59%) and in Type II diabetes mellitus from 17.2 to 2.8/100 000 people (minus 84%). Analysis showed that the diabetic population remained constant despite a considerable fall in the number of older people. During the study period infra-popliteal arterial bypass was introduced for the treatment of critical lower limb ischaemia and in diabetic patients the number of bypasses increased from 0 to 13/100 000 population. The total number of revascularisation procedures it? people with diabetes increased from 2.6 to 19.2/100 000 population. Moreover a multidisciplinary diabetic foot clinic was established. Conclusion/interpretation. A 75% reduction in the incidence of major amputations coincided with a sevenfold increase in revascularization procedures and the establishment of a multidisciplinary diabetic foot clinic suggesting these measures are important in the prevention of diabetic leg amputations.
