Receiving care in multiple health care settings often means that patients obtain medication from different prescribers. Unfortunately, medication information is often poorly documented and poorly transferred between health care settings which introduces the risk on drug-related problems (DRPs). Previous studies often focused at medication incongruities at hospital admission. This thesis aimed to disentangle the problems with continuity of care at time of readmission to primary care and to investigate the role of the community pharmacist within this process.
