Acute cardiac care & resuscitation
Identifying individuals satisfying the termination of resuscitation rule but having potential to achieve favourable neurological outcome following out-of-hospital cardiac arrest
Authors' conclusion
A simple scoring model comprising age, first documented cardiac rhythm, and transport time effectively stratified the likelihood of achieving favourable neurological outcome in patients satisfying the BLS TOR rule.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) patients satisfying basic life support (BLS) or advanced life support (ALS) termination of resuscitation (TOR) rules, All-Japan Utstein Registry, 2010–2019
- Participants

- Exposure
- BLS TOR vs ALS TOR
- BLS TORn = 1,086,092
- ALS TORn = 409,498
- Outcome
- Favourable neurological outcome (cerebral performance category 1 or 2)
- Follow-up
- 1 month post-arrest
