Brief summary
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.
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.
Interventions
DEVICEAutomated External Defibrillator (AED)
Deployment of AEDs
OTHERTraining in cardiopulmonary resuscitation and AED use
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
OTHERActivation of citizen responders
Citizen responders will be activated in case of suspected cardiac arrest through the heart runner app.

Masking description
Due to the nature of the study, treatment allocation is not masked to rescuers or patients. The steering committee will, during the study, receive information on total numbers of arrests and overall success of providing defibrillation. The steering committee will not receive information on whether defibrillation took place in areas allocated to intervention or no intervention. Only the safety committee will have access to all information.
