Large retrospective propensity matching study looking at mortality in trauma patients based on ALS vs. BLS transport crew found lower mortality in those attended by ALS crews. The matching was “based on patient age, sex, year, ICD-10-CM based injury severity score, mechanism of injury, AIS based body region of injury, EMS characteristics including time with patient and prehospital interventions performed, prehospital vital signs, and trauma center designation.”
This is different than other studies which showed limited difference. other studies have shown improved survival with police “scooping and running” with penetrating trauma patients.
