Edmonton Frailty Scale (EFS) Calculator
Frailty score assessment
Enter the domain scores from a properly administered assessment. This calculator only sums the values entered.
Use a validated, correctly administered frailty instrument and interpret the findings in the context of the patient's overall clinical assessment.
This page adds the nine entered values; it does not administer or independently validate the official Edmonton Frail Scale questionnaire. The domain ranges in the source file have not been confirmed as equivalent to the licensed instrument.
About frailty assessment
The Edmonton Frail Scale (EFS) is a multidimensional frailty screening instrument developed for use in older adults. The published scale assesses multiple domains, and its total score is interpreted only when the instrument is administered and scored according to the authorized instructions.
Published score interpretation
| Score | Published category |
|---|---|
| 0–5 | Not frail |
| 6–7 | Apparently vulnerable |
| 8–9 | Mildly frail |
| 10–11 | Moderate frailty |
| 12–17 | Severe frailty |
Important: These published categories should not be applied to this calculator's summed score until the domain definitions, scoring ranges, and total possible score have been reconciled with the authorized EFS version. The supplied source code's listed ranges do not establish equivalence to the published 0–17 scale.
