Patients included (18-80 years) will be randomized to an intervention and a control group. In addition to ordinary health care, the intervention group receives follow-up from a clinical pharmacist during one year with three meeting points, at discharge, after three months and after one year. The control group receives only ordinary health care, but are called in after one year for data collection. Patients living in nursing homes, patients already receiving pharmaceutical follow-up elsewhere and cancer patients are excluded from the study. Only patients living in the area of Tromsoe and nearby is included, as they need to physically see the pharmacist.
