Abstract

Background Increased harmful effects of medication resulting from polypharmacy, especially among older patients, is a significant concern globally. Hence, continuous medication review and withdrawal of inappropriate medications are essential to improve patient safety. Objective To explore physicians' perceived barriers and enablers of deprescribing among older patients in the public primary healthcare setting. Setting Public primary care clinics in the northern states of Malaysia. Methods A semi-structured, face-to-face interview was conducted among physicians working in eight primary care clinics in northern Malaysia using a purposive sampling approach. Interviews were conducted using validated topic guides. All the responses were recorded, transcribed verbatim, validated, and analysed for the emerging themes using thematic analysis. Main outcome measure Physicians perceived barriers and enablers of deprescribing among geriatric patients. Results A total of eleven physicians were interviewed. Seven emerging themes were identified, which are categorised under barriers and enablers of deprescribing. The barriers were patient-specific, prescriber-specific, and healthcare provision and system. Prescriber deprescribing competencies, medication-specific outcomes, availability of empirical evidence, and pharmacist's role were the enablers identified. Conclusion Patient-specific barriers were identified as a significant challenge for deprescribing. Improving competencies on deprescribing was the repeatedly adduced enabler by physicians. The development of targeted educational training can help to reduce the obstacles faced by prescribers.
