Sex differences in OHCA survival, Norwegian registry
Sex differences in OHCA outcomes are driven by arrest circumstances rather than different EMS treatment: a nationwide registry study from Norway 2015 to 2024
Resuscitation · Added 27 July 2026
We found differences in baseline characteristics and treatment performed by Emergency Medical Services (EMS) between women and men, as well as differences in survived event and survival to 30 days.
- Study type
- Registry
- Design
- Retrospective 10-year national registry cohort with multivariable regression
- Participants
- 27,621 EMS-treated OHCA cases (32% women)
- Main finding
- Women had higher odds of survived event (adjusted) but lower 30-day survival; treatment differences did not appear sex-related, and sex differences in survival were unexplained by included variables
- Caveat
- Retrospective registry data; residual confounding — survival differences remained unexplained
- Bottom line
- Context only
Learning goal
Weigh how patient sex and arrest circumstances influence outcomes and my treatment priorities in out-of-hospital cardiac arrest.
