Observational Study Examining the Association of Baseline Frailty and Postcardiac Surgery Delirium and Cognitive Change

Abstract

Compared to nonfrail patients, both prefrail and frail patients were at higher risk for the primary outcome of delirium after cardiac surgery. Frail patients were also at higher risk for the secondary outcome of greater decline in cognition from baseline to 1 month, but not baseline to 1 year, after surgery.
