Effect of an in-hospital medication self-management intervention (SelfMED) on medication adherence in polypharmacy patients postdischarge: protocol of a pre–post intervention study

Healthcare providers usually manage medication for patients during hospitalisation, although patients are expected to self-manage their medication after discharge. A lack of self-management competencies is found to be associated with low adherence levels and medication errors harming patients' health. Currently, patients seldom receive support or education in medication self-management. When self-management is allowed during hospitalisation, it is rarely provided using a structured, evidence-based format. Therefore, an in-hospital medication self-management intervention (ie, SelfMED) was developed based on current evidence. To date, empirical data demonstrating the effect of SelfMED on medication adherence are lacking. This study primarily aims to evaluate the effect of the SelfMED intervention on medication adherence 2 months postdischarge in polypharmacy patients, as compared with usual care.
