Deprescribing practices in Canada: A scoping review

Factors Influencing General Practitioners' Deprescribing Decisions for Older Adults, with Insights into Frailty: a Qualitative Study in Greek Primary Care

INTRODUCTION

Polypharmacy is increasing among older individuals worldwide. Deprescribing has been suggested as a strategy to reduce polypharmacy, but it has had a limited impact.

OBJECTIVE

This study investigated the facilitators and barriers to deprescribing in older adults, as perceived by primary care general practitioners, focusing particularly on factors influencing deprescribing in frail individuals.

METHODS

A qualitative approach was employed and semistructured interviews were conducted between 9 April and 29 May 2024 with a sample of 30 general practitioners working in primary care facilities in Crete, Greece. The interviews were recorded and transcribed verbatim. Thematic analysis was performed on the basis of the Theoretical Domains Framework.

RESULTS

Several barriers to deprescribing were revealed, including a lack of expertise and motivation, inadequate communication skills, time constraints, and negative beliefs toward deprescribing held by physicians and patients. The lack of an established role for general practitioners in primary care, the absence of a national initiative targeting polypharmacy, and the influence of pharmacists and pharmaceutical representatives were highlighted as challenges. The identified facilitators included the incorporation of deprescribing recommendations and considerations for frail patients into guidelines, fostering a strong doctor-patient relationship, promoting shared decision-making, facilitating effective collaboration with caregivers, and utilizing nonpharmacological therapy.

CONCLUSIONS

General practitioners encounter both barriers and facilitators when making deprescribing decisions for older adults, particularly those with frailty syndrome. Researchers and policymakers can use the findings of this research to guide future interventions and promote successful deprescribing practices.

Discontinuation of psychotropic medication: a synthesis of evidence across medication classes

Pharmacotherapy is an effective treatment modality across psychiatric disorders. Nevertheless, many patients discontinue their medication at some point. Evidence-based guidance for patients, clinicians, and policymakers on rational discontinuation strategies is vital to enable the best, personalized treatment for any given patient. Nonetheless, there is a scarcity of guidelines on discontinuation strategies. In this perspective, we therefore summarize and critically appraise the evidence on discontinuation of six major psychotropic medication classes: antidepressants, antipsychotics, benzodiazepines, mood stabilizers, opioids, and stimulants. For each medication class, a wide range of topics pertaining to each of the following questions are discussed: (1) Who can discontinue (e.g., what are risk factors for relapse?); (2) When to discontinue (e.g., after 1 year or several years of antidepressant use?); and (3) How to discontinue (e.g., what's the efficacy of dose reduction compared to full cessation and interventions to mitigate relapse risk?). We thus highlight how comparing the evidence across medication classes can identify knowledge gaps, which may pave the way for more integrated research on discontinuation.

Outcomes in deprescribing implementation trials and compliance with expert recommendations: a systematic review

BACKGROUND

Deprescribing, defined as discontinuing or reducing the dose of medications that are no longer needed or for which the risks outweigh the benefits is a way to reduce polypharmacy. In 2022, the US Deprescribing Research Network (USDeN) published recommendations concerning the measurement of outcomes for deprescribing intervention studies. The objectives of this systematic review were to identify the outcome categories used in deprescribing intervention trials and to relate them to the previously published recommendations.

METHODS

We searched MEDLINE, Embase, PsychInfo, and the Cochrane library from January 2012 through January 2022. Studies were included if they were randomized controlled trials evaluating a deprescribing intervention. After data extraction, outcomes were categorized by type: medication outcomes, clinical outcomes, system outcomes, implementation outcomes, and other outcomes based on the previously published recommendations.

RESULTS

Thirty-six studies were included. The majority of studies focused on older adults in nursing homes and targeted inappropriate medications or polypharmacy. In 20 studies, the intervention was a medication review; in seven studies, the intervention was educational or informative; and three studies based their intervention on motivational interviewing or patient empowerment. Thirty-one studies presented a medication outcome (primary outcome in 26 studies), 25 a clinical outcome, 18 a system outcome, and seven an implementation outcome. Only three studies presented all four types of outcomes, and 10 studies presented three types of outcomes.

CONCLUSIONS

This review provides an update on the implementation of gold standard deprescribing studies in clinical practice. Implementation outcomes need to be developed and specified to facilitate the implementation of these practices on a larger scale and clinical outcome need to be prioritized. Finally, this review provides new elements for future real-life deprescribing studies.
