Abstract:

Study assessed and compared penetrating traumatic brain injury (TBI) and closed TBI with respect to global outcome and late seizures 2 years after injury. Penetrating TBI consists of TBI accompanied by dural penetration and is usually caused by either projectiles striking the head or the head striking sharp objects. Data were collected at 20 TBI Model Systems rehabilitation centers across the United States. After performing unadjusted penetrating TBI versus closed TBI comparisons, multivariate regression models were built and analyzed for both outcomes by including the following additional predictors: loss of consciousness (LOC), posttraumatic amnesia (PTA) duration, hospital length of stay, age, gender, race, marital status, education level, problem substance abuse, and preinjury employment status. The collapsed Glasgow Outcome Scale (GOS) model showed significant secondary effects of penetrating TBI with employment status. When employed before injury, individuals with penetrating TBI were 2.62 times more likely to have a lower GOS category. The final model for late seizures showed a significant main effect for penetrating TBI. Adjusting for other predictors, individuals with penetrating TBI were 2.78 times more likely than those with closed TBI to be rehospitalized for a seizure. The results of this study demonstrates that penetrating TBI is predictive of poorer global outcome and higher prevalence of late seizures above and beyond what can be predicted by other factors such as LOC, PTA, and age.
