ABSTRACT
Objectives: The purpose of this study was to determine the unique characteristics of violence-related traumatic brain injuries (TBI). Methods: All consecutive patients who underwent head CT due to an acute head injury (n = 3023) at the Emergency Department of Tampere University Hospital (Aug 2010-Jul 2012) were included. A detailed retrospective data collection was conducted in relation to demographics, injury-related data, premorbid health, clinical characteristics, and neuroimaging findings. Results: Patients with violence-related TBIs (n = 222) were compared to patients who sustained a TBI by other mechanisms (n = 2801). Statistically significant differences were found on age, gender, prior circulatory system disease, prior mental or behavioral disorders, chronic alcohol abuse, regular substance abuse, regular medication, alcohol intoxication at the time of injury, narcotics intoxication at the time of injury, and acute traumatic lesion on head CT. The groups did not differ on clinical signs of TBI severity. Conclusions: Young adult males with premorbid mental health history and chronic alcohol abuse are most prone to sustain a TBI due to a violence-related incident. Incidents are often related to alcohol intoxication. However, violence was not consistently associated with more severe TBIs than other mechanisms of injury.
