Witnessed prehospital traumatic arrest: predictors of survival to hospital discharge

Trauma patients are rapidly transported to the hospital for definitive care. Nonetheless, some are alive upon Emergency Medical Services (EMS) arrival but arrest on-scene or during transport. The study objective was to examine EMS-witnessed traumatic arrests to define patients who survived hospital discharge. Patients sustaining EMS-witnessed traumatic arrest and entered into the National Trauma Data Bank were included (2007–2018). Mortality defined groups: survival to hospital discharge vs. in-hospital death vs. death in ED/declared dead on arrival (DOA). ANOVA/Chi-square compared cohorts. Multivariable analysis established factors associated with survival out of ED and to hospital discharge. After exclusions, 14,177 patients met the criteria: 10
