Concurrent and Predictive Validity of a New Frailty Risk Index "FR-IC Index": A Follow-Up Study of Older Outpatients

Geriatr Gerontol Int. 2026 Feb;26(2):e70419. doi: 10.1111/ggi.70419.

Abstract

The FR-IC index demonstrated good concurrent validity for baseline disability and significant predictive validity for 1-year deterioration in disability among older outpatients. This tool may enable effective risk stratification and seamless monitoring of physical and mental capacities across the aging trajectory in clinical settings.
