Clinical Frailty Scale (CFS) Calculator
9-point clinician-rated frailty assessment using CFS v2.0 descriptors
When to use it
Use to summarize overall fitness/frailty of an older adult after clinical assessment. Answer each question top-to-bottom (most frail → least frail). The first matching descriptor suggests a CFS score; confirm against the complete CFS and clinical assessment. An all-No response requires reassessment. Widely used in CKD, transplant listing, and pre-operative evaluation.
