Using the Clinical Frailty Scale in Allocating Scarce Health Care Resources. The role of illness acuity on the association between frailty and mortality in emergency department patients referred to internal medicine. Pulok MH, Theou O, van der Valk AM, Rockwood K. A global clinical measure of fitness and frailty in elderly people. Rockwood K, Song X, MacKnight C, Bergman H, Hogan DB, McDowell I, Mitnitski A. ![]() For novice CFS raters, we developed a classification tree to assist with CFS scoring. Please refer to the CFS Guidance and Trainingsection of this website for more information and resources about using the Clinical Frailty Scale. Most notably, CFS level 2 changed from "Well" to "Fit", level 4 from "Vulnerable" to "Living with Very Mild Frailty", and levels 5-8 were restated as "Living with." mild, moderate, severe, and very severe frailty, respectively (Rockwood & Theou, 2020). In 2020 the CFS was further revised (version 2.0) with minor clarifying edits to the level descriptions and their corresponding labels. We published on the predictive validity of the 9-point CFS in 2020 (Pulok et al., 2020). ![]() Therefore, in 2007 the CFS was expanded from a 7-point scale to the present 9-point scale, and it has been used extensively in that format. Later, it became evident that we needed to distinguish between identifiable groups who were otherwise lumped together in the original scale – severely frail, very severely frail and terminally ill - as clinically distinct groups who required distinctive care plans. The highest grade of the CFS (level 7) as published in 2005, incorporated both severe frailty and terminal illness. It is not a questionnaire, but a way to summarize information from a clinical encounter with an older person, in a context in which it is useful to screen for and roughly quantify an individual’s overall health status. The Clinical Frailty Scale (CFS) was introduced in the second clinical examination of the Canadian Study of Health and Aging (CSHA) as a way to summarize the overall level of fitness or frailty of an older adult after they had been evaluated by an experienced clinician (Rockwood et al., 2005).Īlthough introduced as a means of summarizing a multidimensional assessment in an epidemiological setting, the CFS quickly evolved for clinical use, and has been widely taken up as a judgement-based tool to screen for frailty and to broadly stratify degrees of fitness and frailty.
