Deprescribing: What are the views and factors influencing this concept among patients with chronic diseases in a developed Asian community?

Abstract

Objective: Public primary healthcare clinics in Singapore manage a large proportion of elderly patients with chronic diseases. Inappropriate prescribing of medications and polypharmacy in the elderly are associated with adverse outcomes. It is hence important to stop potentially inappropriate medications in this vulnerable group. An approach coined ‘deprescribing’ has been used to describe a patient-centred process of optimising medication regimens. The study aimed to elucidate patients’ attitudes towards the number of medications they were taking and identify factors that might influence acceptance of deprescription. Method: A cross-sectional study using the validated Patients’ Attitudes Towards Deprescribing (PATD) questionnaire was performed at two public primary healthcare institutions in Singapore. Participants were on regular follow-up at the clinics for chronic disease management and had at least five regular prescription medications. Results: The study found that participants (with a mean age of 68) had an average of four medical conditions and six prescription medications, with the majority (60.3%) expressing that they were taking a large number of medications. Of note, 93.4% of participants were willing to stop one of their medications if advised by the doctor. This was associated with a younger age (<65 years old), not having a discount card for medications and having a higher physician trust score (Wake Forest Physician Trust Score). Conclusions: This study showed that majority of the participants were willing to cease a medication that their physician thought was no longer required. Factors were also identified which potentially may be targeted to facilitate deprescription.
