Context Survival rates for out-of-hospital cardiac arrest are low ; published survival rates in Ontario are only 2.5%. This study represents phase II of the Ontario Prehospital Advanced Life Support (OPALS) study, which is designed to systematically evaluate the effectiveness and efficiency of various prehospital interventions for patients with cardiac arrest, trauma, and critical illnesses.
Objective To assess the impact on out-of-hospital cardiac arrest survival of the implementation of a rapid defibrillation program in a large multicenter emergency medical services (EMS) system with existing basic life support and defibrillation (BLS-D) level of care.
Design Controlled clinical trial comparing survival for 36 months before (phase I) and 12 months after (phase II) system optimization.
Setting Nineteen urban and suburban Ontario communities (populations ranging from 16 000 to 750 000 [total, 2.7 million]). Patients All patients who had out-of-hospital cardiac arrest in the study communities for whom resuscitation was attempted by emergency responders.
Interventions Study communities optimized their EMS systems to achieve the target response interval from when a call was received until a vehicle stopped with a defibrillator of 8 minutes or less for 90% of cardiac arrest cases. (...)
