    Background Major trauma is a leading cause of death. Due to the difficulties to keep a registry of these cases, few studies include all subjects, because they exclude out-of-hospital deaths. The purpose of this work was to compare the epidemiological profiles of out-of-hospital deaths, in-hospital deaths, and survivors over a 10-year period (2010– 2019) of patients who had been treated by Navarre´s Health Service (Spain). Methods Retrospective longitudinal cohort study using data of patients injured by an external physical force of any intentionality and with a New Injury Severity Score above 15. Hangings, drownings, burns, and chokings were excluded. Intergroup differences of demographic and clinical variables were analysed using the Kruskal Wallis test, chi-squared test, or Fisher´s exact test. Results Data from 2,610 patients were analysed; 624 died out-of-hospital, 439 in-hospital, and 1,547 survived. Trauma incidences remained moderately stable over the 10-year period analysed, with a slight decrease in out-of-hospital deaths and a slight increase in in-hospital deaths. Patients of the out-of-hospital deaths group were younger (50.9 years) in comparison to in-hospital deaths and survivors. Death victims were predominantly male in all study groups. Intergroup differences regarding prior comorbidities and predominant type of injury were observed. Conclusions There are significant differences among the three study groups. More than half of the deaths occur out-of-hospital and the causative mechanisms differ in each of them. Thus, when designing strategies, preventive measures were considered for each group on a case-by-case basis.
