Clinical Frailty Scale (CFS)

The Clinical Frailty Scale (CFS) was introduced by the Canadian Study of Health and Aging (CSHA) in 2005 as a way to summarize the overall level of fitness or frailty of an older adult after they'd been evaluated by an experienced clinician.
It was reviewed in 2020 and minor changes were made to the level descriptions and labels.
Guidance and training information is available on the website along with a classification tree to help with scoring.
