Abstract 69: The Pan Asian Resuscitation Outcomes Study (PAROS): Characteristics of Patients with Out-of-Hospital Cardiac Arrest Across 7 Countries in Asia
Objectives: The Pan Asian Resuscitation Outcomes Study (PAROS) Clinical Research Network (CRN) includes Japan, Singapore, South Korea, Malaysia, Taiwan, Thailand, and UAE-Dubai. In this study, we aim to report the characteristics of out-of-hospital cardiac arrests (OHCA) patients and events in Asia.
Methods: This is a prospective, international, multi-center cohort study of OHCA across the Asia-Pacific including data from January 2009 to December 2012. We used a standardised taxonomy and case record form to collect common variables. Data were provided via an online electronic data capture (EDC) system or exported data from national registries. Cases included all OHCA presenting to emergency medical services (EMS) and Emergency Departments. Primary outcome was survival to hospital discharge or survived to 30 days post cardiac arrest.
Results: A total of 66,786 cases from January 2009 to December 2012 were included, of which 40,463 cases were presumed cardiac etiology and resuscitated by EMS. The mean age varied from 49.7 (UAE) to 71.7 (Japan). The proportion of males ranged from 57.9 (Japan) to 82.7 (UAE). Proportion of unwitnessed arrests ranged from 26.4% (Thailand) to 67.9% (Taiwan). Presenting rhythm ventricular fibrillation (VF) ranged from 4.1% (Malaysia) to 19.8% (UAE). Bystander cardiopulmonary resuscitation CPR) rates varied from 10.5% (UAE) to 42.4% (Korea), however < 1.0% of all these arrests received bystander defibrillation. For arrests that were witnessed and VF, the survival rate to hospital discharge varied from no reported survivors to 31.2%. Overall survival to hospital discharge varied from 1.3% to 8.9%.
Conclusion: Characteristics and outcomes of OHCA patients vary widely across Asia. This variation may be related to patient and system differences across countries.
