Does the Clinical Frailty Scale (CFS) compared to the modified Frailty Index (mFI) accurately predict death or new disability in older people after surgery?
For preoperative frailty assessment in older adults, the Clinical Frailty Scale (CFS) is preferred over the modified Frailty Index (mFI) due to comparable accuracy and superior ease of use.
Older people with frailty are significantly more likely to die or experience a new patient-reported disability after surgery. Clinicians performing frailty assessments before surgery should consider the CFS over the mFI as accuracy was similar, but ease of use and feasibility were higher.
