FIM stands for Functional Independence Measure, a rehabilitation abbreviation.

Eighteen-item scale rating independence in self-care, sphincter control, transfers, locomotion, communication and social cognition, each scored from 1 (total assistance) to 7 (complete independence), for totals of 18 to 126.

Example: Admission FIM 52, discharge FIM 89; gain of 37 points.

Usage notes

Developed in the 1980s for the Uniform Data System for Medical Rehabilitation. Medicare removed FIM items from the IRF-PAI in October 2019, replacing them with standardized Section GG self-care and mobility items, though many programs still use FIM internally. Assist levels such as Min A and Mod A come from its scoring tradition.
