Acute cardiac care & resuscitation
Fifteen-year secular changes in the care and outcomes of patients with out-of-hospital cardiac arrest in Japan: a nationwide, population-based study
Authors' conclusion
In Japan, collaborative efforts have yielded commendable achievements in the care and outcomes of patients with OHCA over 15 years through to 2019, while the improvement depended on patient characteristics.
Study context
- Population
- Patients with out-of-hospital cardiac arrest (OHCA) in whom resuscitation was attempted, Japan, 2005–1942.4% women
- Participants
- 1,764,440 patients
- Outcome
- Favourable neurological outcome (Cerebral Performance Category 1 or 2)
- Follow-up
- 1 month after arrest
Main finding
As reported in the abstract
Favourable neurological outcome
- Increase in favourable neurological outcome proportions over 2005-19
- 1.7-3.0%
- OR per 1-incremental year
- 1.03
- Trend toward improved outcomes over time
- P for trend < 0.001
Observational data: associations, not effects.
Further findings
Incidence, median age, bystander cardiopulmonary resuscitation (CPR) and dispatcher instructions
- Increased significantly during the study period
- P < 0.001
Favourable neurological outcome by subgroup
- Remarkable increase in younger patients and those with initial shockable rhythm; improvement varied among prefectures
