Abstract:
Study compared long-term functional outcome trajectories of individuals with traumatic brain injury (TBI) who survive with those who expire more than 5 years after injury, using individual growth curve analysis. Data on the Glasgow Outcome Scale-Extended (GOS-E) and Disability Rating Scale (DRS) were obtained for individuals 16 years and older with a primary diagnosis of TBI who received acute inpatient rehabilitation care in a TBI Model Systems center. Analysis revealed that patients who died several years after injury demonstrated worse functional status at baseline and a steeper rate of decline over time as measured by both the GOS-E and the DRS. There was signi?cant variability in each growth parameter for both instruments. A reduced model was built for each outcome, including all covariates that related signi?cantly to the growth parameters. An interactive tool was created for each outcome to generate individual-level trajectories based on various combinations of covariate values. Findings suggest that individuals with TBI who die several years after injury demonstrate functional trajectories that differ markedly from those of survivors. Opportunities should be sought for health management interventions to improve health and longevity after TBI.
