EMS volume doesn't affect traumatic arrest outcomes

Impact of emergency medical services volume on outcomes and management in prehospital traumatic cardiac arrest: a retrospective cohort study
Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine · Added 20 May 2026

Retrospective cohort examining whether higher EMS encounter volume is associated with better management and outcomes in prehospital traumatic cardiac arrest.

Study type

Registry

Design

Retrospective multicentre registry cohort (French RéAC)

Participants

6,263 traumatic OHCA cases among 151,658 OHCAs, 175 EMS bases

Main finding

No association between EMS TCA volume and survival to hospital admission (OR 1.00; 95% CI 0.99–1.01), ROSC, 30-day survival (OR 1.01; 0.98–1.05) or favourable neurological outcome

Caveat

Retrospective registry data from a physician-staffed French system; limited generalisability

Bottom line

Context only

Learning goal

Understand how service volume and system structure influence prehospital traumatic cardiac arrest outcomes across different models of care.
