Ethics approval and consent to participate
: We informed all patients and their relatives about the study. Patients with an MMSE score of ≥16 were asked to provide signed an informed consent. All capable patients gave written informed consent to participate. For patients with reduced cognitive ability, the relatives signed a presumed informed consent on the patient’s behalf. This approach and the study design were approved by Regional Ethics Committee, West Norway (2013/1765). The trial was registered at clinicaltrials.gov (NCT02238652). We followed the Consort checklist for cluster randomized trials when reporting this study.
