Abstract
Background
The International Liaison Committee on Resuscitation (ILCOR) Research and Registries
Working Group previously reported data on systems of care and outcomes of out-of-hospital
cardiac arrest (OHCA) in 2015 from 16 national and regional registries. To describe
the temporal trends with updated data on OHCA, we report the characteristics of OHCA
from 2015 through 2017.
Methods
We invited national and regional population-based OHCA registries for voluntary participation
and included emergency medical services (EMS)-treated OHCA. We collected descriptive
summary data of core elements of the latest Utstein style recommendation during 2016
and 2017 at each registry. For registries that participated in the previous 2015 report,
we also extracted the 2015 data.
Results
Eleven national registries in North America, Europe, Asia, and Oceania, and 4 regional
registries in Europe were included in this report. Across registries, the estimated
annual incidence of EMS-treated OHCA was 30.0–97.1 individuals per 100,000 population
in 2015, 36.4–97.3 in 2016, and 40.8–100.2 in 2017. The provision of bystander cardiopulmonary
resuscitation (CPR) varied from 37.2% to 79.0% in 2015, from 2.9% to 78.4% in 2016,
and from 4.1% to 80.3% in 2017. Survival to hospital discharge or 30-day survival
for EMS-treated OHCA ranged from 5.2% to 15.7% in 2015, from 6.2% to 15.8% in 2016,
and from 4.6% to 16.4% in 2017.
Conclusion
We observed an upward temporal trend in provision of bystander CPR in most registries.
Although some registries showed favourable temporal trends in survival, less than
half of registries in our study demonstrated such a trend.
