Helicopter Transport Improves Survival Following Injury in the Absence of a Time Saving Advantage

摘要

BackgroundAlthough survival benefits have been shown at the population level, it remains unclear what drives the outcome benefits for helicopter emergency medical services (HEMS) in trauma. While speed is often cited as the vital factor of HEMS, we hypothesized a survival benefit would exist in the absence of a time-savings over ground emergency medical services (GEMS). The objective was to examine the association of survival with HEMS compared to GEMS transport across similar prehospital transport times (PHTT).
