Dispatcher-Activated Neighborhood Access Defibrillation and Cardiopulmonary Resuscitation

Not Applicable

Completed

• Conditions: Out of Hospital Cardiac Arrest
• Interventions: Other: NAD-CPR

• Registration Number: NCT02010151
• Lead Sponsor: Seoul National University Hospital

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.

Arm && Interventions

Group	Intervention	Description
NAD-CPR	NAD-CPR	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.

Primary Outcome Measures

Name	Time	Method
Number of Participants Surviving at Hospital Discharge	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 Outcome Measures

Name	Time	Method
Number of Participants With Good Neurological Recovery	discharge time from first admission from emergency department within 2 month	Cerebral performance category 1 or 2 is defined as good neurological recovery. we compared the good neurological recovery rate between before intervention period and intervention period.
Number of Participants With Pre-Hospital Return of Spontaneous Circulation (ROSC)	hospital arriving time from ambulance within 2 hours	we compared the Pre-hospital return of spontaneous circulation (ROSC) rate between before intervention period and intervention period.
