AbstractFrom 1972 to 1982 there was a 23.9% decline in the number of deaths due to trauma in Nebraska. During this time, an improved emergency medical services (EMS) system was being implemented, including training of EMT's and paramedics, physician education in advanced trauma life support (ATLS), establishment of three helicopter transport services, and designation of trauma centers in the two most populous (of six) EMS regions. Highway safety programs alone could not account for the decline in trauma deaths, since there was almost as great a fall in nonvehicular (21.4%) as vehicular (26.4%) trauma deaths. The much larger decline in prehospital (28.3%) than in-hospital (17.3%) trauma deaths suggested a relationship between the improving EMS system and decreased mortality from trauma. We found that growth of the EMS system, as measured by the cumulative number of EMT's trained, correlated strongly with the decline in prehospital (r = 0.95; p less than 0.001), in-hospital (r = 0.84; p less than 0.001), total (r = 0.95; p less than 0.001), vehicular (r = 0.86; p less than 0.001), and nonvehicular (r = 0.93; p less than 0.001) trauma deaths. Our findings suggest that improvements in the statewide EMS system along with better hospital care have caused a significant decline in the number of trauma deaths over a 14-year period.
