Patient values and preferences on polypharmacy and deprescribing: a scoping review.

Background Understanding how patient values and preferences towards polypharmacy and deprescribing have been studied is important to gain insight on current knowledge in this area and to identify knowledge gaps. Aim To describe methods and outcomes for studying patient values and preferences towards polypharmacy and deprescribing, and to identify gaps in the existing literature. Method A scoping review was conducted on English-language studies that examined patient preferences and values related to polypharmacy and/or deprescribing among community-dwelling adults. MEDLINE, Embase, PubMed, PsycINFO, EconLit, Social Science Citation Index, Science Citation Index Expanded, International Pharmaceutical Abstracts, and CINAHL/AgeLine were searched. Results Thirty articles were included. Surveys (n = 17, 56.7%), interviews/focus groups (n = 9, 30.0%), and mixed methods (n = 3, 10.0%), were commonly used methods. Patients Attitudes Towards Deprescribing (PATD) was the most common tool used (n = 9, 30.0%). Twelve themes related to attitudes, social pressure, and control of polypharmacy/deprescribing were identified. The most frequently-encountered themes included desire or willingness to reduce medication load and influence of healthcare provider on medication use. Conclusion PATD was commonly used to assess preferences and values towards polypharmacy and limited knowledge on patient-important outcomes were addressed. Future research should focus on shared decision-making and communicating risk versus benefit of medications.
