Traumatic brain injury, functional cognition, inpatient rehabilitation


Objective: To identify whether measures of functional cognition, as measured by the FIM during inpatient rehabilitation, predict participation at one, two, and five years after traumatic brain injury (TBI). Setting: Acute inpatient rehabilitation facilities within the Traumatic Brain Injury Model Systems of Care. Participants: 1000 individuals over the age of 16 who sustained a moderate to severe TBI.

Design: Secondary analysis of data from a multicenter longitudinal cohort study. Main Measures: FIM Cognitive and Participation Assessment with Recombined Tools – Objective (PART-O).

Results: Hierarchical linear regression analyses indicated that Total FIM Cognitive scores obtained at discharge from inpatient rehabilitation significantly predicted community participation at one, two, and five years post-injury. Four of the five individual FIM Cognitive subscales did not account for significant variance in participation over and above demographic and clinical TBI severity predictor variables in the regression models at one, two, or five years after TBI. Memory functioning was a significant predictor of community participation at two years post-injury.

Conclusions: These findings support the use of comprehensive rehabilitation programs that target overall cognition to improve community participation in the first five years after TBI. Interventions that incorporate compensatory memory training into rehabilitation may also benefit participation over time. Finally, the importance of participation as a meaningful but underutilized measure of health care outcomes is discussed.
