ObjectivesTo describe the incidence and case-fatality rates of traumatic brain injury (TBI) in young children in Colorado, to compare these injuries based on intentionality and outcome (prehospital death, in-hospital death, or survival), and to model the association of intentionality with TBI-related mortality.MethodsCases were drawn from the 1994-2002 Colorado Traumatic Brain Injury Surveillance System. Incidence and case-fatality rates for intentional and unintentional TBI were calculated. We performed univariate comparisons based on the intentionality and outcome of the TBI. Multivariate logistic regression was used to estimate the association of intentionality and mortality, controlling for injury severity.ResultsOf the 1333 children aged 0 to 36 months with TBI, 340 had intentional and 993 had unintentional TBI. Incidence for intentional and unintentional TBI was 16.1 and 47.0 per 100,000, respectively. Children with intentional TBI had a higher case-fatality rate, in-hospital death rate, and injury severity. Intentional TBI deaths were twice as likely to occur in hospital than prehospital, whereas unintentional TBI deaths were twice as likely to occur prehospital. Intentionality was significantly associated with mortality, with the effect increasing with increasing age.ConclusionIntentionality--independent of severity--raises the mortality of TBI in young children.
