Elderly patients' and GPs' perspectives of patient-GP communication concerning polypharmacy: a qualitative interview study

Aim: The aim of this study was to explore elderly patients' and general practitioners' (GPs') perceptions of communication about polypharmacy, medication safety and approaches for empowerment. Background: To manage polypharmacy, GPs need to know patients' real medication consumption. However, previous research has shown that patients do not always volunteer all information about their medication regimen, for example, such as the intake of over-the-counter medication or the alteration or discontinuation of prescribed medication. Method: A qualitative interview study including patients of at least 65 years old with polypharmacy (>= 5 medications) and their GPs in a German Primary Healthcare Centre. The transcripts from the semi-structured interviews ( n= 6 with patients; n = 3 with GPs) were analysed using a framework analytical approach. Findings: We identified three themes: differing medication plans: causes?; dialogue concerning medication: whose responsibility?; supporting patients' engagement: how? While GPs stated that patients do not always report or might even conceal information, all patients reported that they could speak openly about everything with their GPs. In this context, trust might act as a double-edged sword, as it can promote open communication but also prevent patients from asking questions. Both GPs and patients could name very few ways in which patients could be supported to become more informed and active in communication concerning polypharmacy and medication safety. Conclusion: This study shows that patients' awareness of the significance of their active role in addressing polypharmacy needs to be increased. This includes understanding that trusting the doctor does not preclude asking questions or seeking more information. Thus, interventions which improve patients' communication skills and address specific issues of polypharmacy, particularly in elderly patients, should be designed. GPs might support patients by 'inviting' their contribution.
