Abstract

OBJECTIVE: In an aging population, patients undergoing thyroidectomy and parathyroidectomy are at an increased risk of adverse outcomes; thus, measuring patient frailty is a key metric to assess risk. This study innovatively compares the utility of the Risk Analysis Index (RAI) with the 5-factor Modified Frailty Index (mFI-5) in predicting adverse postoperative outcomes. STUDY DESIGN: Retrospective cohort. SETTING: US hospitals. METHODS: Patients undergoing thyroidectomy or parathyroidectomy procedures were selected from the 2005 to 2020 NSQIP data set. RAI and mFI-5 frailty scores were calculated and stratified: non-frail (RAI:
