Cardiac Arrest in Residential Areas With Mobile First-responder Activation (CARAMBA)
September 14, 2023 updated by: Fredrik Folke, Emergency Medical Services, Capital Region, Denmark
A Cluster Randomized Clinical Trial of Strategic AED Deployment in High-risk Residential Areas Combined With Activation of Local Residents
The study aims to increase proportions of bystander defibrillation during out-of-hospital cardiac arrest (hereof referred to as cardiac arrest) in residential areas with a high density of cardiac arrests.
The intervention consists of Automated External Defibrillators (AEDs) and residents' involvement in resuscitation through training and enrollment as citizen responders.

Conditions
Detailed Description
Survival decreases by 10% for every minute that passes after a cardiac arrest until defibrillation.
Despite an increasing number of available AEDs, survival and defibrillation rates in residential areas remain poor.
Efforts to increase bystander defibrillation has the potential to improve survival.
Through the strategic deployment of AEDs, training, and recruitment of residents as citizen responders, we aim to improve proportions of bystander defibrillation and 30-day survival in densely populated residential areas with a high density of cardiac arrests.

Deployment of AEDs
Residents will undergo 30-minute courses at study start and if needed during the trial period.
During the course they will also be recruited as citizen responders
Citizen responders will be activated in case of suspected cardiac arrest through the heart runner app.
