Introduction. Managing polypharmacy is particularly demanding for general practitioners as coordinators of care. Recently, a German guideline for polypharmacy in primary care has been published. This paper describes the content and delivery of a tailored intervention, which aims at improving the implementation of guideline recommendations for polypharmacy into practice, considering individual barriers. Materials and Methods. Firstly, barriers for implementation and the corresponding strategies to address them have been identified. On this basis, an intervention consisting of a workshop for health care professionals and educational materials for patients has been developed. The workshop focused on knowledge, awareness, and skills. The educational materials included a tablet computer. Practice teams will elaborate individual concepts of how to implement the recommendations into their practice. The workshop has been evaluated by the participants by means of a questionnaire. Results. During the workshop 41 possible sources of medication errors and 41 strategies to improve medication management have been identified. Participants evaluated the workshop overall positively, certifying its relevancy to practice. Discussion. The concept of the workshop seemed appropriate to impart knowledge about medication management to the participants. It will have to be evaluated, if the intervention finally resulted in an improved implementation of the guideline recommendations.
