The Illinois Trauma System: changes in patient survival patterns following vehicular injuries

To assess the impact of the Illinois Trauma Program on Region 5, Southern Illinois, samples of vehicular injuries and deaths were compared for a four-year study period: two years prior to system implementation (FY 1970-1971) and two years after system initiation (FY 1972-1973). Trauma center hospitals exhibited a statistically significant decrease in mortality rate during FY 1972-9173 while other hospitals (those in the region not designated as trauma centers) had no change in mortality rate. Decreases in mortality rates were statistically significant at trauma hospitals for weekends and patients between the ages of 45 and 64. The methodology of conducting such a study as well as the implications of the study are discussed.
