Frailty Index associated with postoperative complications and mortality after lower extremity amputation in a national veteran cohort.
Surgical frailty and its assessment have become essential considerations in perioperative management for the modern aging surgical population. The risk analysis index is a validated frailty score that has been proven to predict short-term outcomes and long-term mortality in several surgical subspecialties and high-risk procedures. We examined the association of risk analysis index scores with postoperative outcomes in a retrospective nationwide database of patients who underwent lower extremity amputation in the Veterans Health Administration Health Care System. ⋯ Risk analysis index assessment of frailty was found to be associated with several postoperative outcomes in a dose-dependent manner in patients undergoing lower extremity amputation in the Veterans Health Care System, with higher scores associated with higher rates of death and major cardiac (myocardial infarction, cardiac arrest), pulmonary (pneumonia, failure to wean vent, reintubation), and renal (renal insufficiency, renal failure) complications. We recommend the use of risk analysis index score as a frailty screening tool for patients undergoing lower extremity amputation to enable providers to adequately inform and counsel patients regarding potential significant risks.
