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).
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| NAD-CPR | Experimental | 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. |
|
| Conventional dispatcher assisted CPR | No Intervention | When dispatcher detects OHCA, they instruct the caller with CPR instructions. This is conventional dispatcher assisted CPR performed in Seoul. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| NAD-CPR | 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. |

| TM sent | TM means text message sent to the volunteers. In Seoul, dispatcher asked two key questions regarding altered mental status and abnormal breathing for suspected arrest according to the DA-CPR protocol. When a cardiac arrest was suspected, the dispatchers pushed a button to send a short text message containing the location of the arrest and nearest PAD to registered volunteers within the same geographic neighborhood. | Count of Participants | Participants |
