The HeartRunner Trial

Public Access Defibrillation by Activated Citizen First-responders - The HeartRunner Trial

• Status: Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 1,600 (estimated)
• Sponsor: Emergency Medical Services, Capital Region, Denmark · Other Government
• Sex: All
• Age: 8 Years

Summary

The study will assess 30-day survival for cases where volunteer citizen responders ('heart runners') were activated through a smartphone app to retrieve an AED in case of suspected out-of-hospital cardiac arrest (OHCA) versus standard emergency medical services care. The study will randomize emergency medical dispatch center incoming calls which are suspected out-of-hospital cardiac arrest, such that half will be randomized to activation of heart runners and half to no activation of heart runners (standard care). The study will also assess physical or psychological risks involved for the activated heart runners.

Detailed description

Chances of survival after out-of-hospital cardiac arrest decrease 10% per minute from collapse until defibrillation. Activating volunteer citizens through the emergency medical dispatch center can potentially increase rates of bystander defibrillation and survival. The HeartRunner trial will investigage the effect of activating registered volunteer citizens through a mobile app integrated with the emergency medical services on 30-day survival following out-of-hospital cardiac arrest. Both arms will receive standard care by the Emergency Medical Services. The intervention arm will additionally receive the activation of volunteer citizen responders. The randomization will take place independently in 3 different strata according to heart runner distance to OHCA (\< 3 min, 3-9 min, \> 9 min). The trial will also assess whether it is safe, both physically and psychologically, to activate volunteer citizen responders to respond to out-of-hospital cardiac arrests.
