FIM
Also written as: FIM — Functional Independence Measure
Functional Independence Measure: a standardized assessment tool measuring physical and cognitive disability and functional independence levels.
Full Definition
The Functional Independence Measure (FIM) is an 18-item ordinal scale used to assess functional independence in activities of daily living. Each item is scored on a 7-point scale ranging from total assistance (1) to complete independence (7). The FIM includes 13 motor items covering self-care, sphincter control, transfers, and locomotion, plus 5 cognitive items addressing communication and social cognition. Widely used in rehabilitation settings, the FIM provides standardized measurement of disability burden and tracks functional outcomes over time. It serves as a common language among healthcare professionals and is required for Medicare reimbursement in inpatient rehabilitation facilities. FIM scores help determine appropriate level of care and predict discharge planning needs.
Usage
Usage note: Requires certification for administration; distinguish from WeeFIM (pediatric version).
