Use of deprescribing search filters in systematic review search strategies: A case study.

Two deprescribing search filters for MEDLINE and one deprescribing search filter for Embase have been recently developed, including objectively developed search filters. The objective of this case study was to implement these three deprescribing search filters in systematic review (SR) search strategies and to assess their effect on performances. SR that independently developed original search strategies (OSS) were selected. The deprescribing filters were implemented in each OSS, generating two implemented search strategies (ISS1 and ISS2) in MEDLINE and one ISS (ISS3) in Embase. OSS were re-run on the same date as ISS. The performances of ISS and OSS were calculated and compared. Two SR were included (SR1 and SR2). For MEDLINE, SR1 included 12 articles. The sensitivity was 50% for OSS, 58% for ISS1 and 42% for ISS2. SR2 included four articles. The sensitivity of OSS, ISS 1 and 2 was 25%. For Embase, SR1 included 12 articles. The sensitivity was 33% for OSS and 58% for ISS3. SR2 included four articles. None of the four included articles were retrieved with OSS or ISS3. While sensitivity of OSS was moderate, the objectively developed deprescribing filters maintained or slightly improved this sensitivity when implementing.

Multidisciplinary DEprescribing review for Frail oldER adults in long-term care (DEFERAL): Implementation strategy design using behaviour science tools and stakeholder engagement.

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.

Identification of Potentially Inappropriate Medications in Frail Older Adults Residing in Long-Term Care: A Retrospective Chart Review Study.

INTRODUCTION: Deprescribing is associated with positive health outcomes for older adults in long-term care (LTC), however deprescribing is not universally implemented. OBJECTIVE: The primary aim of this study was to estimate the prevalence of potentially inappropriate medications (PIMs) prescribed to frail older adults in Irish long-term care facilities (LTCFs), as identified by the Screening Tool of Older Persons Prescriptions in Frail adults with limited life expectancy, version 2 (STOPPFrail v2). METHODS: A retrospective chart review was conducted in two publicly funded LTCFs in Ireland. Eligible participants were those (1) ≥ 65 years of age; (2) resident in a LTCF; (3) eligible as per the STOPPFrail v2 criteria by the site's Medical Officer; and (4) receiving regular medication. Data collected included age, sex, drug, dose, frequency, regular/pro re nata prescribing and indication/relevant diagnoses. Rates of polypharmacy (taking five or more medications) and excessive polypharmacy (taking 10 or more medications) were calculated. STOPPFrail v2 was used to identify PIMs; however, clinical measurements were not taken. Descriptive and association statistics were calculated. RESULTS: Of the 103 residents, 89 were ≥ 65 years of age and categorised as frail and were therefore eligible for inclusion in the study. Of those eligible, 85 (95.5%) had polypharmacy and 57 (64%) experienced excessive polypharmacy. The mean number of regular medications was 10.8 (± 3.8), total medications 17.7 (± 5) and diagnoses 5.5 (± 2.5). The mean number of PIMs per resident was 4.8 (± 2.6). Of the eligible participants, 59.6% had at least one medicine without a documented indication, while 61.8%, 42.7% and 30.3% had at least one PIM from the vitamin D, antihypertensives and proton pump inhibitors drug classes, respectively. CONCLUSION: Medication and PIM use was high among LTC residents, with inappropriate polypharmacy of concern. Lack of clear indication for prescribing medications appears to be an issue in LTC, potentially affecting healthcare professionals' engagement with deprescribing. The prevalence of PIMs may be overestimated in the antihypertensives/antidiabetic classes due to the lack of clinical measurements.

General practitioners' perceptions of pharmacists working in general practice: a qualitative interview study.

BACKGROUND: Pharmacists are being increasingly employed as part of general practice teams globally, and their input has been associated with several clinical and economic benefits. However, there is a paucity of research focussing on general practitioners' (GPs') perceptions of pharmacist integration into practices in countries where this novel role for pharmacists is yet to become commonplace. OBJECTIVE: To explore GPs' perceptions of integrating pharmacists into general practices and to identify the behavioural determinants of GPs integrating pharmacists into practices. METHODS: Semistructured interviews were conducted with GPs practising in Ireland, who were sampled using a combination of purposive, convenience, and snowball sampling. Interviews were audio-recorded and transcribed verbatim, which then were analysed using conventional content analysis and directed content analysis employing the Theoretical Domains Framework (TDF). RESULTS: Seventeen GPs were interviewed between November 2021 and February 2022. Seven TDF domains were identified as predominant in influencing GPs' perceptions of pharmacist integration into general practices. These perceptions were mostly positive, especially regarding patient outcomes, cost savings, and improving access to care. However, there were concerns about funding the role, affecting others' workloads, and pharmacists' training needs to work in practices. CONCLUSION: This study's theory-informed insight provides a deeper understanding of GPs' perceptions of pharmacists working in general practice and behaviours which can be targeted to help optimize integration. These findings should be utilized in future service development to preempt and address GPs' concerns ahead of pharmacist integration, as well as to inform the development of general practice-based pharmacist roles going forward.

This interview study focusses on, for the first time, general practitioners' (GPs') perceptions of pharmacist integration into general practices outside of a private practice setting. Pharmacists working in general practices have demonstrated several benefits for patients, GPs, practices, and for wider society. However, pharmacist roles in general practices have thus far been confined to a small number of countries; little is known about the perceptions of GPs who have not previously worked alongside a pharmacist in general practice regarding pharmacist integration in this setting. GPs interviewed in this study were broadly optimistic about aspects of pharmacists working in practices and potential outputs. However, GPs had concerns about pharmacists' impact on others' roles and workloads, funding, and training pharmacists to perform roles in this setting. This study therefore provides a useful insight into GPs' perceptions on the subject so that their views, concerns, and ideas can be anticipated and taken on board in advance of trying to integrate pharmacists into practices.

Barriers and enablers to deprescribing in long-term care: A qualitative investigation into the opinions of healthcare professionals in Ireland.

INTRODUCTION: The prevalence of polypharmacy increases with age, increasing the exposure of older adults to potentially inappropriate medications (PIMs). Deprescribing has been shown to reduce PIMs for older residents in long-term care; however, deprescribing is not universally implemented. This study aims to identify the barriers and enablers to deprescribing in Irish long-term care facilities from the healthcare professionals' (HCPs) perspective. METHODS: A qualitative descriptive approach was conducted using semi-structured interviews with HCPs working in long-term care (general practitioners, pharmacists and nurses). Purposive sampling with maximum variation was applied to select long-term care sites to identify HCPs, supplemented with convenience sampling of post-graduate HCPs from University College Cork. Data was thematically analysed and mapped to a framework of deprescribing barriers and enablers informed by the Theoretical Domains Framework. RESULTS: Twenty-six HCPs participated from 13 long-term care facilities. The main barriers and enablers identified mapped to five domains. Barriers included insufficient resources, lack of co-ordination between healthcare settings and negative social influences. Additional barriers exist in private settings including deprescribing awareness, commitment and the need for incentives. Deprescribing enablers included interprofessional support and patient social influence. To encourage deprescribing, potential enablers include HCP education, pharmacist role expansion and tailored deprescribing guidelines within a structured process. CONCLUSION: Interventions to support deprescribing should build on existing systems, involve stakeholders and utilise guidelines within a structured process. Any intervention must account for the nuanced barriers and enablers which exist in both public and private settings.

Assessing community pharmacists' attitudes towards identifying opportunities for deprescribing in clinical practice in Ireland.

OBJECTIVES: The main objective of this study was to assess community pharmacists' thoughts regarding the role they can play in effectively integrating deprescribing into clinical practice in Ireland. The aim was to assess pharmacists' (1) knowledge of deprescribing, (2) confidence in deprescribing, (3) attitudes towards deprescribing and (4) barriers and facilitators to deprescribing in a community pharmacy setting. METHODS: An online questionnaire was disseminated to pharmacists currently registered with the Pharmaceutical Society of Ireland, with instruction only to complete if working in community pharmacy. Statistical analysis was conducted on the quantitative data, whereas thematic analysis was carried out on the open-ended responses. KEY FINDINGS: Results indicate good knowledge scores and positive attitudes surrounding deprescribing, with demographic factors having no significant effect on results. Although deprescribing knowledge is high, willingness to engage is hindered by obstacles such as time. Remuneration was identified as an enabler for deprescribing. Interdisciplinary educational opportunities and bidirectional communication channels with prescribers are viewed as the major facilitators of deprescribing. CONCLUSIONS: Community pharmacists demonstrate that they possess sufficient knowledge, confidence and willingness to play a greater role in facilitating deprescribing. To enable this role expansion, enablers such as education and funding need to be implemented, to overcome barriers such as insufficient time. Further studies are required to assess community pharmacists' deprescribing competence, to demonstrate their ability to fulfil this role in clinical practice in Ireland.

Barriers and enablers to deprescribing in long-term care facilities: a 'best-fit' framework synthesis of the qualitative evidence.

INTRODUCTION: older adults are at risk of adverse outcomes due to a high prevalence of polypharmacy and potentially inappropriate medications (PIMs). Deprescribing interventions have been demonstrated to reduce polypharmacy and PIMs. However, deprescribing is not performed routinely in long-term care facilities (LTCFs). This qualitative evidence synthesis aims to identify the factors which limit and enable health care workers' (HCWs) engagement with deprescribing in LTCFs. METHODS: the 'best-fit' framework approach was used to synthesise evidence by using the Theoretical Domains Framework (TDF) as the a priori framework. Included studies were analysed qualitatively to identify LTCF barriers and enablers of deprescribing and were mapped to the TDF. Constructs within domains were refined to best represent the LTCF context. A conceptual model was created, hypothesising relationships between barriers and enablers. RESULTS: of 655 records identified, 14 met the inclusion criteria. The 'best-fit' framework included 17 barriers and 16 enablers, which mapped to 11 of the 14 TDF domains. Deprescribing barriers included perceptions of an 'established hierarchy' within LTCFs, negatively affecting communication and insufficient resources which limited HCWs' engagement with deprescribing. Enablers included tailored deprescribing guidelines, interprofessional support and working with a patient focus, allowing the patients' condition to influence decisions. DISCUSSION: this study identified that education, interprofessional support and collaboration can facilitate deprescribing. To overcome deprescribing barriers, change is required to a patient-centred model and HCWs need to be equipped with necessary resources and adequate reimbursement. The LTCF organisational structure must support deprescribing, with communication between health care systems.
