Clinical Frailty Scale

^[1]^[2]^[3]

Indications

a measure of frailty based on clinical judgment
originally a 7 point scale
- very fit = 1
- well = 2
- well with treated comorbidity = 3
- apparently vulnerable = 4
- mildly frail = 5 (limited dependence for iADL)
- moderately frail = 6 (needs help with both bADL & iADL)
- severely frail = 7 (completely dependent for bADL & iADL)
- very severely frail = 8 (completely dependent, approaching end-of-life)*
- terminally ill = 9 (life expectancy < 6 months, not otherwise evidently frail)*
9 point scale ranging from very fit to terminally ill^[3]
- assesses cognition, comorbidity, & function

* two items added to the original 7 point scale^[1]^[3]
