title: [Trends and characteristics of diabetes-related lower limb amputations in the Negev, 1996-1999].
abstract: BACKGROUND
  The loss of a lower limb because of diabetic foot problems such as infections is an important complication of diabetes mellitus. The goals of this study were: (1) to examine trends in incidence of diabetic-related lower limb amputations in the Negev, (2) to describe the clinical characteristics of patients who underwent amputations in the Soroka University Medical Center and (3) to estimate in-hospital mortality and its predictors.
  
  
  METHODS
  This study included all diabetic patients who underwent non-traumatic lower limb amputation in the Soroka Hospital during the period 1996-1999. The computerized hospitalization files and surgery logs during the study period were reviewed for ICD-9 diagnoses of diabetes and amputations. For each patient, hospitalization records were abstracted and data on socio-demographic and clinical characteristics were collected.
  
  
  RESULTS
  During the study period 411 amputations were performed on 250 diabetic patients (1.6 amputation/person). The estimated mean annual incidence rate of lower limb amputations in the Negev was 5 per 1000 diabetic patients, 27.3 per 100,000 total population, and 45 per 100,000 adults above 18 years of age. The mean age was 68 (SD +/- 11.4) years. The most frequent types of surgery were standard below-knee amputation. Fourteen percent of patients died during hospitalization. Systolic blood pressure, white blood count and serum creatinine at admission were independent predictors of in-hospital mortality.
  
  
  CONCLUSIONS
  The incidence of lower limb amputation in the Negev is similar to that reported in other countries. Interventions directed to early detection of diabetic foot problems may have an impact on the reduction of lower limb amputations and related mortality.
