Method: This descriptive, retrospective, analytical study conducted from June December 2020. data 153 patients an ISS score ≥ 16 selected registries both facilities. According transport duration, were assigned one four groups: <15 minutes (group 1); 30 2); 31-45 3) > 45 4). Both groups according TRISS equal mortality expected survival rate margin taken at 70% due this being approximate intrahospital our patients. primary in-hospital mortality, secondary included hospital stay, ICU stay 30-day rate. Results: We found no statistically significant difference relation pre-hospital when scene (p = 0,186). ruled out any 0,179 p 0,173, respectively) among preselected time. Also, day unaffected by led 0,156). Conclusion: With strategically placed EMS beginning scene, transport.
