Participants
A total of 946 patients were assessed for eligibility at the two hospital wards. Of these, 319 patients failed to meet the inclusion criteria and 377 patients either declined the invitation to participate, were asleep, discharged or transferred to another ward at the time of inclusion.Thus, 250 participants were included in the study and randomized into a control group (n = 50) and an intervention group (n = 200). In the follow-up period, 98 participants (17 in the control group and 81 in the intervention group) were considered as non-responders. Finally, 33 participants were interviewed in the control group and 119 participants in the intervention group; see
