Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

NAD-CPR

Intervention Type OTHER

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.

Conventional dispatcher assisted CPR

When dispatcher detects OHCA, they instruct the caller with CPR instructions. This is conventional dispatcher assisted CPR performed in Seoul.

Group Type NO_INTERVENTION

No interventions assigned to this group

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.
