Database for Atrial Fibriliation


Primary variables


List of variables not avaliable for download


The Database for Atrial Fibrillation in Denmark (AFDK) is a clinical quality database that contains data on patients with atrial fibrillation from all hospitals and general practice in Denmark.
AFDK is aimed at ensuring high quality treatment and care and harmonising treatment for patients with atrial fibrillation.

AFDK is anchored in the Danish Cardiology Society (DCS). The database seeks to ensure that relevant patients are offered treatment for the right indication and to increase compliance with clinical guidelines. The database includes hospital and general medical practice so as to promote coordination between sectors and ensure that handover between sectors can be done without loss of quality.

Data is reported via patient administration systems to the National Patient Register (LPR) in the form of SKS codes and cross-batched with data from the The Central Person Registry (CPR) and the prescription database.

The Regional Clinical Quality Databases

Data about clinical quality are collected with the purpose of monitoring and raising the quality of patient treatment in the Danish health-care system. These data can, as well as all other public registers, be made accessible for research projects based on systematic protocols and approved according to the relevant legislations.

Applying for access to data from a regional clinical database requires a list of demands to be obtained. A project description should be attached containing a description of the project explaining the rationale, purpose, methods, budget, publication plan etc.

Furthermore, The Danish Data Protection Agency must approve the project.

Application process

  • Apply via research access (Danish: forskeradgang), an online application system
  • Submit the protocol to The Danish Clinical Registries (RKKP)
  • RKKP registers the application
  • The application is forwarded to the relevant clinical database
  • Potential dialog about adjustment to the protocol
  • Approval and extradition of data (expected 6 months after application)
