Women's OHCA survival edge fades by discharge
Sex differences in epidemiology, care, and outcomes in patients with out-of-hospital cardiac arrest in China
Resuscitation · 2026-11 · Added 26 September 2026
A prospective Chinese multicentre cohort of 33,650 EMS-treated OHCA patients found women had better prehospital ROSC and survival to admission than men but no advantage at discharge, with the early benefit lost in older and shockable-rhythm patients.
- Study type
- Cohort
- Design
- Prospective multicentre population-based observational cohort
- Participants
- 33,650 EMS-treated OHCA patients (BASIC-OHCA, 2020)
- Main finding
- Women had higher odds of prehospital ROSC (aOR 1.21) and survival to admission (aOR 1.33) but no significant difference in survival to discharge or favourable neurological outcome
- Caveat
- Single-country cohort with large unmeasured differences in prehospital care pathways and male-female arrest aetiology
- Bottom line
- Hypothesis-generating
Why it matters in Australia (Medium relevance). A Chinese EMS system differs from Australian models in dispatcher coverage and bystander rates, but the sex-difference question is one Australian registries are also probing, so it informs rather than guides practice.
Learning goal
Recognise how sex influences resuscitation pathways and outcomes in out-of-hospital cardiac arrest care in Australia.

Rescue breaths help in non-cardiac arrest
A nationwide Japanese registry cohort of 154,137 non-cardiac OHCA patients found bystander rescue-breathing CPR was associated with slightly lower 30-day mortality and unfavourable neurological outcome than compression-only CPR, with the clearest benefit in children and drowning arrests.

No evidence on screening arrest survivors' psychology
Systematic review of structured identification and assessment of psychological, emotional or cognitive problems in cardiac arrest survivors — of 1,605 records screened, none met eligibility, so there is no evidence base for which screening instruments, thresholds, timing or referral pathways should be used.
