Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (2)

  • Number of Participants With Pre-Hospital Return of Spontaneous Circulation (ROSC)

    hospital arriving time from ambulance within 2 hours

  • Number of Participants With Good Neurological Recovery

    discharge time from first admission from emergency department within 2 month

Study Arms (2)

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.

Other: NAD-CPR

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.

Interventions

NAD-CPROTHER

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.

NAD-CPR
