Data must be taken with reservations for the differences in the ways municipalities register. Over time within one municipality changes can also occur regarding coverage and/or practice, which can lead to shift in level. Since data are not available for all municipalities it is not possible to publish data for the regions and the whole country.
Overall accuracy
Data display a degree of uncertainty. There may be significant variations in the ways the municipalities organize and register home nursing.
There are differences in the way delegated home nursing services performed by other than district nurses are registered, which complicate comparability. Furthermore the coverage of home nursing services can vary, since some municipalities include nursing centers and others do not.
The services are divided into type of services according to a standardized set of nursing services. The statistics use a version from before 2013 and thus not use the most recent version of these types.
In a few municipalities significant shifts in level can be observed. Reasons for this is best explained by the relevant municipalities.
Sampling error
Not relevant for these statistics.
Non-sampling error
The coverage is not complete. Approximately 85 of 98 municipalities monthly transfer data on home nursing to Statistics Denmark. 93 municipalities has at some point delivered data.
Quality management
Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.
Quality assurance
Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.
Quality assessment
The quality of the statistics on home nursing is not optimal, since large variations between municipalities are observed. The definition of data and the implementation in the care systems was in 2010. There are several sources to uncertainty in data, e.g. differences in the municipalities way of organizing, planning and delivering home nursing services. Also there are different care system providers and thus different it system, which can cause differences. Cautiousness is adviced when comparing between municipalities.
Data revision - policy
Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.
Data revision practice
If new data or revised data are delivered for already published periods, this new data will be part of the following new version of the statistics.
