The register data received from the National Patient Register is linked with background data from Statistics Denmark and counts are made, e.g. number of admissions and number of out-patient treatments at public and private somatic and psychiatric hospital departments during the calendar year.
Source data
External sources: The National Patient Register. The data is delivered by The Danish Health Data Agency (from 2012-2015 from SSI and before 2012 from the Danish Health Authority) LPR3 data is available for 2019-2021, and annual (LPR3) data delivery is expected to resume from 2022.

Data collection
Extracts from the master tables of the National Patient Register in the Danish Health Data Agency are transmitted via a secure connection to Statistics Denmark.
Data validation
The Danish Health Data Agency is responsible for the operation and validation of the National Patient Register.
Totals and subtotals are compared as far as possible with figures from the Danish Health Data Agency.
Data compilation
The Hospital Utilization Statistics contains the following information for each contact during a calendar year: date of admission and discharge, emergency or non-emergency admission, and diagnose classification group.
For each person, the individual contacts (physical attendance) are linked if there is a maximum of 4 hours between them. Total hospital stay is calculated from the contact's start to end time. Hospitalization vs. Outpatient visits are then defined according to a physical stay-duration criterion (over or under 12 hours of hospital stay, with under 12 hours being outpatient).
Diagnosis is selected as the time-dominant action diagnosis during the same hospitalization.
