title: Emergency department dispositions among 4100 youth injured by violence: a population-based study.
abstract: OBJECTIVE
  Concern about youth violence in Canada is growing. Because victims of violence are more likely to become future violent perpetrators, preventative interventions are often based out of inpatient units; however, the question of how often youth who have been injured due to violence are discharged from emergency departments (EDs), or whether there are opportunities for emergency healthcare workers to deliver violence prevention programs, is not known. The primary objectives of this study were to describe the frequency and patterns of violent injuries among youth, to determine how many injured youth are discharged directly from EDs and to estimate the proportion of injured youth who may benefit from ED-based intervention programs.
  
  
  METHODS
  We conducted an observational study using a population-based database that records information on all ED visits in Ontario. We analyzed age, sex, cause of injury and disposition for all patients aged 12-19 years who presented to Toronto EDs with violent injuries during a 2-year period (April 2002 to March 2004).
  
  
  RESULTS
  A total of 4100 patients aged 12-19 years visited Toronto EDs with violent injuries during the study period. Assault due to bodily force (in contrast to sharp objects, guns or other) was the most common injury mechanism, accounting for 48.7% of cases (95% confidence interval [CI] 47.1%-50.2%). The majority of patients (89.3%; 95% CI 88.3%-90.2%) were discharged directly from EDs, including 44% of gun-related injuries.
  
  
  CONCLUSIONS
  In Toronto, a large proportion (89.3%) of youth injured in violent incidents are discharged directly from EDs. There are opportunities to develop ED-based youth violence prevention initiatives.
