This scale was devised by a pioneering Canadian geriatrician called Ken Rockwood and is widely used the world over as a validated frailty assessment tool based on the Phenotype model of frailty (i.e., based on what people with different levels of frailty severity look like and on their level of dependency for activities of daily living).


The British Geriatric Society (BGS) publication ‘Fit for Frailty’ (Part 1) recommends the use of this scale only after a person has had a comprehensive geriatric assessment but some healthcare organisations in the UK have chosen to use it as a tool to identify frailty in individuals before this has happened because the scale is very simple to understand and use in clinical settings.

An increasing score on the Clinical Frailty Scale strongly correlates with functional decline and increasing mortality rates and is a highly specific frailty assessment tool.
