title: Rates of thoracic trauma and mortality due to accidents in Brazil.
abstract: OBJECTIVE
  To report on the causes of trauma, indexes of trauma, and mortality related to thoracic trauma in one region of Brazil.
  
  
  METHODS
  This prospective study was performed at the Regional Trauma Center in São José do Rio Preto over a 1-year period, from 1(st) July 2004 to 30(th) June 2005. We included all patients attending the center's emergency room with thoracic trauma and an anatomic injury scale (AIS) ≥ 2. We collected data using a protocol completed on arrival in hospital utilizing the AIS. We studied the types of accidents as well as the mortality and the AIS scores. Prevalence rates were calculated and the paired t-test and logistic regression were employed for the statistical analysis.
  
  
  RESULTS
  There were a total of 373 casualties with AIS ≥ 2 and there were 45 (12%) deaths. The causes of thoracic trauma among the 373 casualties were as follows: 91 (24.4%) car crashes, 75 (20.1%) falls, 46 (12.3%) motorbike accidents, 40 (10.7%) stabbings, 22 (5.9%) accidents involving pedestrians, 21 (5.6%) bicycle accidents, 17 (4.6%) shootings, and 54 (14.5%) other types of accident. The severity of the injuries was classified according to the AIS: 224 (60%) were grade 2, 101 (27%) were grade 3, 27 (7.2%) were grade 4, 18 (4.9%) were grade 5, and 3 were (0.8%) grade 6. With respect to thoracic trauma, pedestrians involved in accidents and victims of shootings had mortality rates that were significantly higher than that of those involved in other types of accidents.
  
  
  CONCLUSIONS
  Road accidents are the main cause of thoracic injury, with accidents involving pedestrians and shootings being associated with a greater death rate.
