Statistical presentation

Data description

The statistics cover admissions to and outpatient treatments at public and private somatic hospital wards within one calendar year. The statistics are based on the National Patient Register from Danish Health Data Authority combined with a number of background details from other registers. The statistics show e.g. how the use of hospitals varies with a range of sociodemographic factors.

Classification system

The following classifications are applied in connection with publication of Hospitalization statistics:

• Diagnosis (the time-dominant main diagnosis during the hospitalization). Diagnoses are grouped according to the International Classifications of Diseases ICD - on aggregated 23 and 99 groups (the S list) from WHO. More on classification of diseases available on The SKS browser and the National Health Agency. In 2023, 2 new tables (respectively indl001 and ambu001) have been added for the years 2019-2022. These tables show data on 19 main diagnostic categories. The 19 main categories largely reflect the overall ICD10 main chapters or main diagnosis groupings seen at the Danish Health Data Agency The SKS browser and who.int at https://icd.who.int/browse10/2019/en#/XIX. The individual admission or individual outpatient visit is assigned a time-dominant ICD10 diagnosis code for the hospital stay, after which the dominant action diagnosis codes are divided into these 19 overall main diagnosis groups
• Admissions (emergency, planned)
• Out-patient treatment (emergency, planned)
• Geography (municipalities and regions)
• Public or private hospital
• Hospital service type (somatics - psychiatry - both parts). The hospital stays can be categorized according to somatics, psychiatry or both (i.e. hospital stays where there has been physical attendance in both somatic and psychiatric hospital services)
• Family type (children living at home; singles without children living at home; singles with children living at home; couples without children living at home; couples with children living at home)
• Ancestry (persons of Danish origin; immigrants; descendants).
