Senior Health Calculator: Online Tool for Providers
For Providers: Online Tool to Calculate Frailty Index (FI)
This online calculator applies the standard deficit-accumulation approach 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. The following categories of frailty are used in clinical practice and research: robust (less than 0.15), pre-frailty (0.15 to less than 0.25), mild frailty (0.25 to less than 0.35), moderate frailty (0.35 to less than 0.45), severe frailty (0.45 to less than 0.55), and advanced frailty (0.55 or higher).
Typically, most of the population has a CGA-FI value less than 0.70. People with a higher CGA-FI value are at greater risk for loss of independence, poor recovery after surgery, and disability after medical hospitalization.
