Abstract

Introduction
Reducing overprescribing in primary care through targeted structured medication reviews (SMRs) is a national priority. Shared decision-making and a multidisciplinary team (MDT) approach to SMR are recommended for successful deprescribing (stop/reduce inappropriate medications) among older people, specifically those with frailty.

Aim
To develop a multidisciplinary medication review and deprescribing intervention in primary care for older people with frailty.

Methods
The intervention development involved two stages and was informed by the Medical Research Council framework for complex intervention. Stage one involved intervention planning and included: 1) a realist review of 28 articles that identified 35 context-mechanism-outcome (CMO) configurations for successful MDT medication review and deprescribing in primary care[1] and 2) a qualitative study with 26 primary care healthcare professionals (HCPs) including GPs, pharmacists, and advanced clinical practitioners, and 13 older people with polypharmacy and their informal carers recruited from two general practices within Wessex. Using the person-based approach, drawing on the COM-B model for behaviour change, and a normalisation process theory lens, the findings of these two studies informed the development of intervention’s guiding principles.
Stage two involved intervention development based on six co-design online workshops with key stakeholders (n=25), including primary care HCPs recruited from across the South region, patient and carer representatives, and the research management team. The intervention guiding principles were presented in these workshops and possible intervention content, format and delivery were proposed, discussed and refined through an iterative process. Workshop data were analysed drawing on a rapid analysis method and a final version of the intervention was agreed.

Results
The final version of the complex intervention consisted of five main components based on findings from stages one and two: 1) Proactive identification of patients with frailty and polypharmacy for targeted SMR using the electronic frailty index embedded in primary care health systems and the UK national polypharmacy prescribing comparators, 2) HCPs preparation to conduct SMR through targeted education on deprescribing and identifying and prioritising high-risk medications for deprescribing using evidence-based deprescribing tool(s), 3) Preparing and educating patients and carers about the purpose of SMR and reasons for potentially stopping or changing medications (patient leaflet sent prior to SMR), 4) Conducting a person-centred SMR that includes in-person, phone or virtual appointments tailored to patient and carer needs and preferences, involving other MDT members based on their expertise, documenting and sharing any agreed changes with patients and other staff members, and 5) Tailored follow-up plans that allow continuity of care and management and include highlighting specific signs and symptoms for patients and carers to monitor following medication changes, and arranging further contact through text, phone or in-person follow-up appointment.

Conclusion
The use of multiple research methods has led to the development of a complex MDT medication review and deprescribing intervention for older people with frailty and drawing on behaviour and implementation theories could potentially maximise the intervention’s feasibility, acceptability and successful implementation. A mixed-method study in primary care is currently underway to test the feasibility and acceptability of intervention implementation, in preparation for a full trial.
