Objective: To examine the attitudes and beliefs about medication burden and deprescribing among persons living with Parkinson disease (PD)

Background: Deprescribing of potentially inappropriate medications is recommended for older adults and may improve health outcomes and quality of life in persons living with PD. Patient attitudes, beliefs, and preferences play a crucial role in the success of deprescribing interventions.

Method: We administered a survey to participants of Fox Insight, a prospective longitudinal study of persons living with PD. The survey included the revised Patients’ Attitudes Towards Deprescribing (rPATD) questionnaire and additional questions about adverse drug effects. We used logistic regression models to explore potential predictors of treatment dissatisfaction and willingness to deprescribe.

Results: Of the 4945 rPATD respondents, 31.61% were dissatisfied with their current medications, and 87.06% would be willing to deprescribe medications. Male sex was associated with a greater willingness to deprescribe (adjusted odds ratio [aOR] 1.62, 95% confidence interval [CI] 1.37-1.93). A greater belief that medication burden was high or that some medications were inappropriate was associated with treatment dissatisfaction (aORs of 3.74, 95% CI 3.26-4.29 and 5.61, 95% CI 4.85-6.50), and more willingness to deprescribe (aORs of 1.74, 95% CI 1.47-2.06 and 2.87, 95% CI 2.41-3.42). Cognitive impairment was the adverse drug effect participants were most concerned about when prescribed medications to treat nonmotor symptoms.

Conclusion: Persons with PD are often dissatisfied with their medications and are open to deprescribing. Medications that are associated with cognitive impairment should be prioritized targets for deprescribing interventions in this population.
