ObjectiveThis article describes the characteristics of violence-related injury (VRI) cases presenting at emergency departments (EDs) in Brazil and compares circumstances for assault-related and self-inflicted cases.MethodsThe study is cross-sectional. The data describe cases seen in September 2006 in 62 EDs, representing all 26 states and the Federal District. A total of 4 835 case records were analyzed. Basic statistical tabulations were complemented by logistic regression analysis to assess potential associations between type of violence (assault or self-harm) and multiple factors.ResultsMales comprised 72.8% of cases while those aged 20 to 29 comprised 35.4%. Alcohol use was reported or suspected in 42.7% of cases, more commonly among males. Assault victims comprised 91.4% of cases versus self-inflicted injuries, which accounted for 8.6%. Three-fourths of the assault victims were male, while over half of the self-inflicted injury victims were female. The leading mechanism for assaults was physical force/blunt objects (46.2%), whereas poisoning was the predominant mechanism for self-inflicted injuries (71.4%). Younger females were significantly more likely to have been victims of self-inflicted injuries than younger males, while younger males were more likely to have been victims of assault; this finding is more pronounced in cases where alcohol use was reported. Self-inflicted injuries were significantly more likely to occur in residences, while assaults were more likely to occur away from home.ConclusionThese results can improve understanding of the scope and characteristics of VRIs in Brazil (and thus contribute to national injury prevention efforts), and help identify areas for future research.
