Ethics approval and consent to participate
: The Regional Ethics Committees for Medical and Health Research Ethics in Norway (south-east region) approved an exemption from the Duty of Confidentiality for a third person (referred to as ‘contact’) who was employed at the involved hospitals and had access to the documentation system, to select, retrieve, and anonymize the included EPRs (Ethics Committee case number: 2016/2035/REK). Permission to access the EPRs was obtained through the data protection officer at each participating hospital, and the hospital management selected our contact, who retrieved and anonymized the EPRs. Due to the sensitivity of the material, we agreed to not reveal the names of the hospitals.
