Study examined the rates and causes for rehospitalization in the 10 years after moderate-severe traumatic brain injury (TBI), and identified individual factors associated with the probability of rehospitalization over time. Secondary analysis was conducted of data for individuals 16 years and older with a primary diagnosis of TBI who were enrolled in the Traumatic Brain Injury Model System National Data Base. Rehospitalization (and reason for rehospitalization) as reported by participants or proxy during follow-up telephone interviews at 1, 2, 5, and 10 years postinjury were analyzed. Generalized linear mixed models and individual growth curve models were applied to help explain individual variability in rehospitalization risk over time. The greatest number of rehospitalizations occurred in the first year postinjury (27.8 percent of the sample), and the rates of rehospitalization remained largely stable (22.1 to 23.4 percent) at 2, 5, and 10 years. Reasons for rehospitalization varied over time: Orthopedic and reconstructive surgery rehospitalizations were most common in year 1, whereas general health maintenance was most common by year 2 with rates increasing at each follow-up. The longitudinal models indicate that multiple demographic and injury-related factors are associated with the probability of rehospitalization over time. These findings can inform the content and timing of interventions to improve health and longevity after TBI.
