Using the risk analysis index to assess frailty in a veteran cohort undergoing endovascular aortic aneurysm repair

Surgical frailty is strongly associated with increased perioperative morbidity and mortality. The risk analysis index (RAI) is a validated frailty score system, which has been shown to predict for short-term outcomes and long-term mortality in various surgical subspecialties. In the present study, we applied the frailty score to a veteran aneurysm population who had undergone nonemergent endovascular aortic aneurysm repair (EVAR).After obtaining...
