About this tool

This is the short version of the Clinical Frailty Scale (CFS) classification tool. Instead of asking about each activity and condition one by one, it asks for counts: how many basic and instrumental activities of daily living your patient needs help with, and whether they have 10 or more chronic conditions. Depending on the answers, it asks between two and seven questions.

It follows the same decision tree as the full version and gives a CFS level from 1 (very fit) to 9 (terminally ill).

Interpreting the result

The result is a CFS level from 1 to 9, shown with its pictogram and description. The tool supports, but does not replace, clinical judgement.
