Data are from the National Hospital Discharge Register and are received annually. Information is applied about admissions to, outpatient treatments at and emergency room visits to public somatic hospital wards during the calendar year. If a person is transferred during a hospital stay from one hospital ward to another, this will count as two admissions. The number of bed days in connection with admissions is applied. Accordingly, the units in the statistics are persons, admissions and bed days, outpatient treatments and emergency room visits. The statistics are broken down by sex, age, diagnosis, region of residence and a number of background variables: family type, occupational group, education, type of accommodation, ancestry and job function. (Up to and including 2008, the statistics were also broken down by predominant social security benefit).

Statistics Denmark compares the received data with data from the previous year and any major variations are investigated. If we observe any seeming errors, we contact the Danish Health Data Agency for the purpose of clarification. We also assess the internal data, and in cases of doubt we contact the person in charge of the statistics for further explanation.
In the Hospitalisation Statistics Register, the following information exists for any person who has resided in Denmark during a calendar year about the person’s admissions to hospital:
In the Hospitalisation Statistics Register, the following information is available for each admission during the calendar year:
The method of calculation of the number of outpatient treatments is the number of visits in the year, and if the same person has several visits on the same day, this is only counted as one treatment.
Type of discharge for emergency room visits:
The assessments include an index (illustration of the concept admission rate) which is defined as the share of a given population group that has been hospitalised. Age standardisation is applied for a number of the assessments, since the hospitalisation rate varies strongly with age. As from 2000, further standardisation is made as far as adults are concerned for socio-economic grouping and as far as children are concerned for the families’ educational level.
