Funding for the CARAMBA project and its community-based cardiac arrest intervention.
Research
CARAMBA investigates whether a targeted intervention in public housing communities can increase early defibrillation and improve survival after out-of-hospital cardiac arrest.

Study design
The trial compares residential communities with and without the complete CARAMBA intervention.
Study design
13 public housing communities are included in the study
Intervention areas are compared with control areas
The intervention is tested in a real-world setting
Outcomes are assessed using the Danish Cardiac Arrest Registry
Background
Although survival after out-of-hospital cardiac arrest has improved in Denmark, most cardiac arrests still occur in private homes, where early defibrillation remains rare.
CARAMBA therefore focuses on residential communities where improved defibrillator access, local training and volunteer responder recruitment can make a tangible difference.
Each year in Denmark
5,000+
out-of-hospital cardiac arrests
Where it happens
75%
occur in private homes
Early defibrillation
~5%
receive bystander defibrillation in private homes
Study structure
The study combines clinical outcomes with a practical intervention designed for local implementation and long-term anchoring.
01
Primary outcome
Defibrillation performed by a resident or another bystander before the ambulance arrives.
02
Secondary outcome
The study also examines survival 30 days after the cardiac arrest.
03
The intervention
Strategic defibrillator deployment, hands-on resuscitation training and recruitment of local volunteer responders.
04
Implementation
The intervention is implemented with a focus on local anchoring, realistic operation and practical everyday use.

From study to practice
CARAMBA combines research, practical training and local implementation. The project works with ambassadors, instructors and residential communities to strengthen cardiac arrest response.
Ambassadors in the residential communities help create visibility, participation and local ownership.
Local instructors support hands-on training in resuscitation and defibrillator use.
Training with feedback equipment makes the teaching concrete, measurable and action-oriented.
Funding and collaboration
CARAMBA is funded by TrygFonden and the Independent Research Fund Denmark. Project partners contribute training, equipment, research expertise, local anchoring, ambulance support and defibrillators.
