Cardiac arrest & resuscitation
Improving emergency medical services (EMS) response times for out-of-hospital cardiac arrest in urban areas using drone-like vertical take-off and landing air ambulances: An international, simulation-based cohort study
Authors' conclusion
VTOL air ambulances dedicated to OHCA response may improve EMS response intervals, with substantial improvements in ALS response metrics.
Study context
- Population
- Adult Out-of-hospital Cardiac Arrest (OHCAs) in Greater Paris (France) and Metro Vancouver (Canada), Jan. 2017-Dec. 2018
- Participants
- 6,217 OHCAs
- Exposure
- Simulated 1-2 advanced life support (ALS)-capable vertical take-off and landing (VTOL) air ambulances vs historical EMS response
- Outcome
- Call-to-ALS arrival interval and call-to-first EMS arrival interval
Methodological detailsinternational, 2 urban centres (France, Canada), Greater Paris n = 3,760; Metro Vancouver n = 2,457
