: The study was carried out as a regulatory audit, thus as a part of the annual working plan of The Norwegian Board of Health Supervision (NBHS). The legal basis for evaluating the data is the Health Care Supervision Act, and the Health Research Act does not affect this project. A request was forwarded to the Regional Committee for Medical and Health Research Ethics (REK), and the conclusion was that the project was not obliged by law to obtain a separate ethical approval (reference 2016/1500B). All data were treated and stored in accordance with relevant public administration legislation and the NBHS’s internal guidelines.
