Proportions were calculated based on the denominator of total deaths in each region (eg, all rural proportions add to 100%). The absolute number of deaths was calculated based on the full sample of injured patients served by EMS in these regions during the study period (n = 67 047). Among patients injured in rural regions, there were 29 deaths (15 [51.7%] out-of-hospital, 11 [37.9%] at ≤24 hours, and 3 [10.3%] at >24 hours). Among patients injured in urban regions, there were 583 deaths (143 [24.5%] out-of-hospital, 230 [39.5%] at ≤24 hours, and 210 [36%] at >24 hours). The overall mortality comparison demonstrated rural mortality of 1.44% (95% CI, 0.96-2.15) vs urban mortality of 0.89% (95% CI, 0.68-1.17; P = .09 for comparison). ED indicates emergency department.
