For Providers: Online Tool to Calculate Frailty Index (FI)
This online calculator applies the standard deficit-accumulation approach (see references below) to routinely collected items of a comprehensive geriatric assessment (CGA) to calculate the frailty index (FI). For calculation of FI, medical history and functional status sections must be completed; information on performance tests and nutritional status is not required (the calculator will use all available information).
Interpretation of CGA-FI
The CGA-FI can range from 0 to 1, with higher values indicating a greater degree of frailty.
