Study used hierarchical linear modeling to examine baseline predictors of functional independence trajectories across 1, 2, 5, and 10 years after traumatic brain injury (TBI) in older adults. Participants were 2,459 individuals aged 60 or older at the time of TBI who were enrolled in the longitudinal TBI Model Systems database. Each had Functional Independence Measure Motor and Cognitive subscale scores and Glasgow Outcome Scale-Extended scores during at least 1 time point. Functional independence trajectories generally declined over the 10 years after TBI. Individuals who were older, male, underrepresented minorities, had lower education, were unemployed at time of injury, had no history of substance use disorder, or had difficulties with learning, dressing, and going out of the home prior to the TBI, or longer time in posttraumatic amnesia had lower functional independence trajectories across at least one of the functional independence outcomes. These predictors of functional independence in older adults with TBI may heighten awareness of these factors in treatment planning and long-term health monitoring and ultimately as a way to decrease morbidity and mortality.
