Each advanced prehospital intervention adds scene time
The impact of advanced pre-hospital interventions on scene time
Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine · Added 5 May 2026
Retrospective physician-led HEMS trauma study examining whether more advanced interventions are stretching scene times — each additional intervention increased scene time by 41%, although overall scene times stayed similar over two decades because of changing case mix.
- Study type
- Cohort
- Design
- Retrospective observational study of physician-led air ambulance
- Participants
- 1,357 injured patients
- Main finding
- 26% received an advanced intervention; each additional intervention increased scene time by 41% (p<0.001). Median scene times stayed similar between 2005–2010 and 2017–2021 (10 vs 25 min penetrating vs blunt, p<0.001).
- Caveat
- Retrospective, single physician-led HEMS service; July-only sampling of each year
- Bottom line
- Context only
Learning goal
Weigh the clinical benefit of advanced scene interventions against their impact on scene time in trauma care.
