Acute cardiac care & resuscitation
European registry of cardiac arrest study THREE (EuReCa- THREE) – Emergency Medical Services (EMS) response time influence on outcome in Europe
Authors' conclusion
The results of EuReCa-THREE highlight continuing variation in the incidence, management and outcomes from OHCA across Europe. For patients who were EMS-treated, results indicate clear associations between response times and the likelihood of survival.
