Abstract:

INTRODUCTION: Deprescribing is a strategy for reducing the use of potentially inappropriate medications for older adults. Limited evidence exists on the development of strategies to support healthcare professionals (HCPs) deprescribing for frail older adults in long-term care (LTC). OBJECTIVE: To design an implementation strategy, informed by theory, behavioural science and consensus from HCPs, which facilitates deprescribing in LTC. METHODS: This study was consisted of 3 phases. First, factors influencing deprescribing in LTC were mapped to behaviour change techniques (BCTs) using the Behaviour Change Wheel and two published BCT taxonomies. Second, a Delphi survey of purposively sampled HCPs (general practitioners, pharmacists, nurses, geriatricians and psychiatrists) was conducted to select feasible BCTs to support deprescribing. The Delphi consisted of two rounds. Using Delphi results and literature on BCTs used in effective deprescribing interventions, BCTs which could form an implementation strategy were shortlisted by the research team based on acceptability, practicability and effectiveness. Finally, a roundtable discussion was held with a purposeful, convenience sample of LTC general practitioners, pharmacists and nurses to prioritise factors influencing deprescribing and tailor the proposed strategies for LTC. RESULTS: Factors influencing deprescribing in LTC were mapped to 34 BCTs. The Delphi survey was completed by 16 participants. Participants reached consensus that 26 BCTs were feasible. Following the research team assessment, 21 BCTs were included in the roundtable. The roundtable discussion identified lack of resources as the primary barrier to address. The agreed implementation strategy incorporated 11 BCTs and consisted of an education-enhanced 3-monthly multidisciplinary team deprescribing review, led by a nurse, conducted at the LTC site. CONCLUSION: The deprescribing strategy incorporates HCPs' experiential understanding of the nuances of LTC and thus addresses systemic barriers to deprescribing in this context. The strategy designed addresses five determinants of behaviour to best support HCPs engaging with deprescribing.
