Computer-supported identification and intervention for diabetic patients at risk for amputation.

: We used the fully automated medical record system at Kaiser Permanente of Ohio to direct appropriate interventions to diabetic patients at risk for amputation. The computer identified all patients with a diagnosis of diabetes, reminded physicians, at the moment of care, of the need to enter the patient's risk status for amputation, and kept track of patients at medium or high risk for amputation who were due for an evaluation with education in the podiatry department. Two years and four months after activation of this reminder system, the risk level had been determined for 76% of the diabetic population (n = 10,000), and two thirds of those at medium or high risk had received the appropriate intervention. In patients in the medium and high risk groups, the risk ratio for amputation was 17.5.
