Sundhedsdatastyrelsen

Sundhedsdatastyrelsen (The Danish Health Data Authority) is a Danish government agency responsible for governing health data in Denmark. Its mandate is to enable the secure, lawful, and efficient use of health data for the benefit of patient care, public health, and medical research, while protecting individuals' privacy.

The agency administers the national health data infrastructure, including health data registers and data-exchange systems, and sets technical and legal standards for data collection, storage, sharing, and use. It authorizes access to health data for research and other legitimate purposes, typically in anonymized or pseudonymized form, and supervises compliance with data protection rules under GDPR and Danish health data legislation.

Sundhedsdatastyrelsen collaborates with the Regions of Denmark, hospitals, universities, and other authorities to promote data-driven health services and research. It provides guidance, develops interoperability standards, and publishes statistics and guidance related to health data governance and use.
