Method
MIH
A randomized controlled study design was used in the present study. The study was registered at clinicaltrials.gov with the identification number NCT03829995. Participants were randomized 1:4 (50:200) into a control- and intervention group. Participants in the control group were offered standard care and those in the intervention group were offered access to the MIH. A telephone interview performed 2–4 weeks after discharge assessed patient satisfaction with the helpline and patient’s feeling of safety in relation to medicine use (primary outcome). Data were analyzed using a Mann-Whitney U test. After case handling of each enquiry to the MIH, the cases were assessed with regard to medication-related problems (MRPs) and clinical impact of the MIH service was assessed (primary outcome).
