DUSAS - Danes treated at foreign hospitals


Primary variables





Municipality of residence

Patient on treatment by specialist practice

Patient treatment at hospital abroad

Patient type

Referring body

Treating hospital /department



DUSAS contains data on the treatment of patients at foreign hospitals paid for by the patient's region of residence and details of treatment of patients in specialist practice that are not billed under the normal health service agreement but are agreed with and paid by the region of residence.

The register was set up as a result of the introduction of central pool funding for additional activities at hospitals in 2002 and contains data from 2002 and thereafter.

DUSAS contributes to healthcare monitoring and quality development and is important for monitoring cancers, since the number of Danish patients treated abroad can contribute to the picture of the quality and organisation of the treatment of cancer in Denmark.
