About

The hypothesis of this study is Dispatcher-Activated Neighborhood Access Defibrillation and Cardiopulmonary Resuscitation (NAD-CPR) would improve survival of out-of-hospital cardiac arrest (OHCA).

Full description

Out-of-hospital cardiac arrest (OHCA) is a major health problem, occurring in about 1 in 1,500 adults in the developed countries each year. Although layperson CPR and defibrillation are crucial components of chain of survival, layperson CPR rate and it's quality is low and public-access defibrillation (PAD) program is not cost-effective.If trained bystanders can know the information of occurrence of OHCA and nearest place for automated external defibrillator (AED) at the same time by dispatch center, these neighborhoods could run and give high quality CPR and early defibrillation. If this protocol ,Dispatcher-Activated Neighborhood Access Defibrillation and Cardiopulmonary Resuscitation(NAD-CPR), is introduced to community, it may improve survival of OHCA.

3,194 participants in 2 patient groups

NAD-CPR
Experimental group
Description:
When dispatcher detects a patient with OHCA, the dispatcher activates trained neighborhoods by informing events nearby using short message service via cellular phone. The neighborhood within geographically accessible area who could perform effective CPR and defibrillation would be alerted with event of OHCA and the nearest AED.
Treatment:
Other: NAD-CPR
Conventional dispatcher assisted CPR
No Intervention group
Description:
When dispatcher detects OHCA, they instruct the caller with CPR instructions. This is conventional dispatcher assisted CPR performed in Seoul.
