OBJECTIVE: To determine risk factors for psychiatric hospitalization after traumatic brain injury (TBI) in veterans. SUBJECTS AND PROCEDURES: Medical records of 96 veterans with histories of TBI (17 mild, 33 moderate, and 46 severe) were reviewed for information concerning psychiatric history, including hospitalization and substance misuse. RESULTS: Subjects with a history of problematic drug and alcohol use had a significantly higher probability of psychiatric hospitalization than those without such a history. Gender, age, problematic alcohol use without problematic drug use, injury severity, time since injury, years of follow-up, and a history of psychiatric symptoms (including those attributed to general medical conditions) were not identified as significant risk factors. Ninety-one veterans (95%) had a history of psychiatric difficulty. In addition, the probability of post-TBI problematic drug and alcohol use, given a pre-TBI history of such use, was significantly higher than the probability given no history. CONCLUSIONS: Veterans with problematic drug and alcohol use are at increased risk for psychiatric hospitalization after TBI. In addition, the likelihood of problematic post-TBI drug and alcohol use was significantly greater for those with a preinjury history. Ninety-five percent of veterans in the current sample endorsed lifetime histories of psychiatric difficulty. These findings highlight the need for evidence-based means of psychiatric and/or substance abuse treatment of those with a history of TBI.
