Barriers and Facilitators to Proactive Deprescribing in Saudi Hospitals: A Qualitative Study Using the Theoretical...

Polypharmacy, commonly defined as the use of five or more medications, is a growing concern in hospitals due to its association with adverse drug reactions, functional decline, and increased healthcare costs. Proactive deprescribing, which involves the planned discontinuation of unnecessary or potentially harmful medications, can optimise medication use. However, multiple barriers hinder its implementation. Saudi Arabia offers a unique context for deprescribing due to strong family roles in care, prevalent prescribing norms, and ongoing shifts toward value-based healthcare. This study explores the barriers and facilitators to proactive deprescribing among physicians in Saudi hospitals using the Theoretical Domains Framework (TDF). The TDF was used as it effectively identifies behavioural factors influencing clinical decision making in practice.

Semi-structured interviews were conducted with 27 purposively sampled physicians experienced in managing polypharmacy. The interviews were transcribed and analysed thematically, with behavioural determinants identified and categorised according to the 14 domains of the Theory of Planned Behaviour (TDF).

Enablers included the availability of deprescribing guidelines, decision-support tools, interprofessional collaboration, and institutional backing. Physicians with specialised training expressed greater confidence in conducting deprescribing. Identified barriers included limited time, heavy workload, absence of standardised protocols, medico-legal concerns, resistance from patients and caregivers, and lack of formal training. These factors were categorised under seven key TDF domains, with Environmental Context and Resources, Social Influences, and Beliefs About Capabilities identified as the most influential in shaping physicians' deprescribing practices. Interactions between factors were observed, where supportive environments and collaborative teams helped offset key barriers such as time constraints, legal concerns, and patient resistance.

This study identified key behavioural and contextual factors influencing proactive deprescribing in Saudi hospital settings. Addressing barriers such as heavy workload, medico-legal concerns, and lack of standardised protocols through targeted interventions, including clinician training, institutional support, and multidisciplinary collaboration, may facilitate the integration of deprescribing into routine practice. The findings offer context-specific insights to inform future efforts aimed at improving medication safety and optimising prescribing in the Saudi healthcare system.
