This study identified a number of significant predictors of per capita county trauma mortality rates: rurality, percentage nonwhite population, percentage unemployment, and Advanced Life Support (ALS) versus Basic Life Support (BLS) status. Of these, ALS versus BLS status is not only the most significant independent predictor, it is the only predictor readily amenable to change. The aspects of ALS clearly associated with decreased trauma death rates should be identified and, if possible, undergo widespread implementation.
