Accuracy and reliability

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 number of hospital admissions) on the new data basis were published at the end of 2022 for 3 calendar years; 2019, 2020 and 2021. The next tables (on out-patient treatments) are published in the spring of 2023.

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

Due to the new data structure in the National Patient Register there is a data breach from 2019.

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 Half of these have now been archived, and new figures have been published for the most used tables, provisionally INDL01, INDL02, AMBU01 and AMBU02 (2019-2021).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.
