PAROS CRN endeavours to improve outcomes from PEC across the Asia-Pacific region through the creation of a platform to support and stimulate research into effective strategies to improve survival in PEC. The ability to reach out to countries across the Asia-Pacific region means that the Network can adopt a multi-pronged strategy that targets key stakeholders such as the community, EMS and the hospitals in its vision to improve PEC outcomes. By offering practical ways of monitoring and meaningful measurement of PEC outcomes, PAROS CRN has an enormous potential to contribute significantly to PEC research, regardless of whether they are epidemiological studies or clinical trials. As a first step, PAROS CRN has identified OHCA as one of its main thrusts. The Network will gather valuable information on OHCA and deepen the understanding of the EMS systems in the region to devise strategies that improve survival. 

Patients presenting with OHCA to the emergency rooms in the countries currently collaborating with PAROS. Countries include: Singapore, Thailand, South Korea, Lebanon, China, Japan, Malaysia, United Arab Emirates, Taiwan, Pakistan, India

All patients who sustain a sudden cardiac arrest in the out of hospital setting. All patients who present to the EDs with OHCA would be recorded and patients electronic record would be reviewed on patients discharge.
