Clinical Frailty Scale (CFS) — Frailty Assessment

The Clinical Frailty Scale (CFS), developed by Rockwood et al. at Dalhousie University, is a rapid 9-point global assessment of frailty in older adults based on clinical judgment and observation. Unlike index-based frailty tools (Fried Frailty Phenotype), the CFS uses a simple narrative and pictographic description of activity level and health status, enabling rapid bedside assessment in 2–3 minutes. The CFS is now widely used in acute hospital, ICU, and emergency settings for frailty-adjusted risk stratification and prognostication.
