Abstract
In an effort to identify variables that could be used to predict outcomes of amputation, a cohort of 97 veteran amputees with a median age of 64 years who underwent 155 lower extremity procedures during 1984 was followed for 15 months. A high incidence of postoperative complication, revision, and mortality with poor quality of life confirm the serious prognosis of these individuals. Regression analyses indicated that peripheral vascular disease and prolonged preoperative hospitalization were associated with complications. Preoperative gangrene and peripheral vascular disease were associated with the need for revision. Complications, a low body mass index, and multiple diseases were related to death. Those with multiple diseases and extensive atherosclerosis were less likely to walk. Ability to perform activities of daily living was the most important predictor of quality of life. Patients at higher risk for these adverse outcomes need to be identified early in their hospital stay. The involvement of the patient or his or her surrogate in decisions regarding the course of treatment and the level of amputation is essential.
