Accuracy and reliability

The National Patient Register is validated by the Danish Health Data Agency and the accuracy of the register data must be considered to be high because the registration has a long tradition and a high priority for administrative purposes. Accordingly, the overall accuracy of the Hospital Utilization Statistics is high.

Timeliness and punctuality

Delay has occurred due to the transition to a new National Patient Register with a new register structure regarding data on admissions. The first tables on the new data basis will be published at the end of 2022 for 3 calendar years; 2019, 2020 and 2021.

Previous to 2019 (LPR2): The statistics are published 5-10 months after the end of the year. The punctuality is high.

Comparability

The new data structure in the National Patient Register means that admissions must be defined in the data analysis. This creates data breaches in the volume of the count for the number of hospitalizations.

On the basis of the previous national patient register version (2006-2018), 52 statistical bank tables were prepared. Half of these have now been archived, and new figures have been published for the most used tables, provisionally INDL01 and INDL02 (2019-2021).

Eurostat and the OECD make comparable data collections and publications in this field. There are a number of organizational and institutional conditions that we must keep in mind when comparing countries.
