PAROS CRN Publications Committees and Publications of Studies

Publications Committees (PCs)

Pan-Asian Resuscitation Outcomes Study (PAROS) Clinical Research Network (CRN) promotes research into resuscitation. To introduce a systematic peer-review of studies proposed under PAROS CRN, the PAROS EXCO approved the formation of four PCs. Each PC focuses on a specific domain in Pre-hospital and Emergency Care, namely Out-of-Hospital Cardiac Arrest (OHCA), Emergency Medical Services (EMS) Systems, Emergency Department (ED) Survey and EMS Survey. The list of the four PCs is as follows (*Denotes PC Chairman):
