Overview
Brief Summary
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).
Detailed 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.

Eligibility Criteria
Inclusion Criteria
- •all OHCA with presumed cardiac etiology more than 15 years old
- •assessed by emergency medical service (EMS) providers dispatched by dispatch center
- •dispatcher detected OHCA patients
Exclusion Criteria
- •OHCA with non-cardiac etiology
- •prolonged cardiac arrest with a suspected duration more than 30 minutes
- •cases with rigor mortis or rivor mortis, decapitated or decomposed body
- •Non detected cases by dispatcher
Outcomes
Primary Outcomes
Number of Participants Surviving at Hospital Discharge
Time Frame: discharge time from first admission from emergency department within 2 month
we compared the survival to discharge rate between before intervention period and intervention period. Survival to discharge checked at the discharge point of hospital.
Secondary Outcomes
- Number of Participants With Good Neurological Recovery(discharge time from first admission from emergency department within 2 month)
- Number of Participants With Pre-Hospital Return of Spontaneous Circulation (ROSC)(hospital arriving time from ambulance within 2 hours)
