Development of a population-level frailty index using Quebec administrative data: a Canadian retrospective study.
A frailty score derived from routine health records can identify vulnerable older adults at population scale, enabling targeted support without extra clinical visits.
This Canadian retrospective study derives and validates a frailty index from Quebec administrative health data (physician billing, hospital admissions, prescriptions) that accurately identifies frail older adults at population scale without requiring clinical assessment. The population-level frailty surveillance tool is compatible with existing administrative databases and supports aging population health planning.
