Older Patients' Perceptions of Medicines and Willingness to Deprescribe.

Major barriers in deprescribing are the ambivalence of patients, resistance to change, and poor acceptance of alternative treatments. To investigate older patients' beliefs, understanding and knowledge, satisfaction with medicine use, health outcome priorities, their attitude toward deprescribing, and to identify associated patient factors. This multi-center cross-sectional, semistructured survey study involved older outpatients (70 years of age and older) with polypharmacy. The survey comprised three validated questionnaires: Beliefs about Medicines Questionnaire, Patients' Attitudes Towards Deprescribing questionnaire, and the Health Outcome Prioritization tool, with additional questions about understanding and satisfaction. The association between questionnaire outcomes and patient characteristics was investigated. Fifty participants were included; they used an average of 9 (+/- SD 2.7) medicines. For most participants (82%), the necessity of using medicines outweighed their concerns. Participants could name 35% of their medicines and 43% of the indications. Overall, 76% were satisfied with the effect of their medicines, but 94% would be willing to stop their medication if advised by their doctor. Maintaining independence (46%) and reducing pain (31%) were the most important health outcome priorities reported by the patients; staying alive had the lowest priority (51%). Participants with higher levels of educational attainment had better knowledge and had more concerns about harmful effects. Patients are open to deprescribing but would probably not initiate the conversation themselves because they are generally very satisfied with their medicines. Knowledge about their medicines and their indications is poor. If doctors initiate deprescribing, patients are probably willing to follow their advice. Patients' life priorities should be discussed in deprescribing conversations.
