About

In this study, we extracted data from the patients medical record within the cohort to compare five existing frailty indices: the 5-Item Modified Frailty Index (mFI-5), the Electronic Frailty Index (eFI), the Frailty Index based on Comprehensive Geriatric Assessment (FI-CGA), the Frailty Risk Assessment Instrument for the Elderly based on Laboratory and Clinical Indicators (FRAIL), and the Hospital Frailty Risk Score (HFRS). The study aims to evaluate the predictive values of each electronic frailty index for the incidence of postoperative infection-related adverse events. This includes the primary outcome of infection events occurring within 30 days and the secondary outcome of the correlations among the five frailty indices.
