Factors associated with pre-hospital care in victims of traffic accidents

This was a cross-sectional study of all victims of traffic accidents in Belo Horizonte, Minas Gerais State, Brazil, admitted to the three largest public hospitals in the city from November 10 to December 14, 2003, to identify characteristics associated with the use of pre-hospital emergency treatment and investigate whether the time between the accident and hospital admission was shorter among these victims. The association between pre-hospital treatment and target variables was assessed by prevalence ratios obtained from Poisson regression. Among 1,564 victims, 778 (49.7%) were transported in vehicles with pre-hospital treatment. Pre-hospital treatment was less common for bicyclists and pedestrians. The prevalence ratio was higher among victims with more severe injuries (AIS = 2 and AIS>or= 3), older victims (30-39 years, 40-49 years, >or= 50 years), those who reported alcohol use, and when the time between accident and hospital admission was less than 60 minutes. According to the results, pre-hospital treatment is more frequent among severely injured victims and helps reduce the time between the accident and hospital admission.
