Cardiac arrest & resuscitation
Emergency medical services agency-level variation in non-initiation of resuscitation and termination of resuscitation in out-of-hospital cardiac arrest
Authors' conclusion
Even after adjustment for measured patient and agency characteristics, we observed substantial between-agency variation in non-initiation of resuscitation and TOR.
Study context
- Population
- Patients with non-traumatic Out-of-hospital Cardiac Arrest (OHCA), ESO Data Collaborative 2018–2024
- Participants
- 560,240 encounters
- Outcome
- Non-initiation of resuscitation and TOR (agency-level variation, median OR)

Main finding
As reported in the abstract
- Resuscitation not initiated (76,859 encounters)
- 13.7%
- Termination of resuscitation (TOR) among 309,048 encounters eligible for Universal TOR rule (175,826 encounters)
- 56.9%
- Median adjusted agency-specific rate, non-initiation (IQR 11.0-16.7%)
- 13.6%
- Median adjusted agency-specific rate, TOR (IQR 35.5-67.4%)
- 54.3%
- Median OR for non-initiation of resuscitation
- 2.30 (95% CI 2.21-2.38)
- Median OR for TOR
- 4.13 (95% CI 3.87-4.26)
