Cardiac Arrest in Residential Areas With Mobile First-responder Activation

Not Applicable

Recruiting

• Conditions: Out-Of-Hospital Cardiac Arrest

• Registration Number: NCT04446585
• Lead Sponsor: Emergency Medical Services, Capital Region, Denmark

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.
