National health registers
The Danish Health Data Authority is responsible for the national health registers that contain data related to the health of the entire Danish population and the services of the healthcare system.
In Denmark, health data is registered when you visit your GP, the hospital or a medical specialist, buy medicine at the pharmacy or receive health services in your municipality. This data is collected in national health registers.
The health registers contain information about e.g. diseases, treatments, finances and employees in the healthcare system. Each register has been established to serve a particular purpose, for instance to monitor the development of a disease or the effect of a treatment.
The National Patient Register is the largest register and contains information about all examinations and treatments in Danish hospitals in the last 40 years.
Based on data in the national health registers, The Danish Health Data Authority regularly publishes analyses and reports on the population's health and the Danish healthcare system.
In The Danish Health Data Authority’s databank – eSundhed – you can look up data for e.g. surgeries, diagnoses, births, causes of death and medicinal products.
