Instruments and Methods

Functional Status Score for the Intensive Care Unit

The Functional Status Score for the Intensive Care Unit (FSS-ICU) is used to evaluate a patient’s physical functioning in an ICU setting. If you wish to access and use the FSS-ICU, please follow this link (to find FSS-ICU, search under the “Physical Outcomes – Tests” heading), and register at this website. Additional resources are available for the FSS-ICU including a pocket card, FAQ, pre-ICU baseline retrospective data collection version, and translated versions. To get updates on revisions to the FSS-ICU and its User Instructions, sign up for the “Newsletter” feature at this website.
