Clinical Trial 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).

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.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 3194
• Est. completion date: December 2017
• Est. primary completion date: December 2017
• Accepts healthy volunteers: No
• Gender: All
• Age group: 15 Years and older

Eligibility

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

Related Conditions & MeSH terms

• Heart Arrest
• Out of Hospital Cardiac Arrest
• Out-of-Hospital Cardiac Arrest

Intervention

Other:
• NAD-CPR
When Dispatcher detects OHCA, short message service (SMS)about the OHCA event and information about the location of nearest AED is sent to trained laypersons within geographically accessible area.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Surviving at Hospital Discharge	we compared the survival to discharge rate between before intervention period and intervention period.; Survival to discharge checked at the discharge point of hospital.	discharge time from first admission from emergency department within 2 month
Secondary	Number of Participants With Pre-Hospital Return of Spontaneous Circulation (ROSC)	we compared the Pre-hospital return of spontaneous circulation (ROSC) rate between before intervention period and intervention period.	hospital arriving time from ambulance within 2 hours
Secondary	Number of Participants With Good Neurological Recovery	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.	discharge time from first admission from emergency department within 2 month
