Self-reported reasons for reducing or stopping antidepressant medications in primary care: thematic analysis of the diamond longitudinal study

Antidepressant deprescribing: State of the art and recommendations-A literature overview

INTRODUCTION

In recent years, the consumption of antidepressants has arisen. However, deprescribing antidepressant therapy is very complicated. The aim of this study was to implement practical recommendations for the development of guidelines to be used for antidepressant deprescription in clinical practice.

MATERIALS AND METHODS

The literature search has been conducted on March 13, 2023, using Scopus and PubMed databases. The following search string has been used: "antidepressants AND (deprescribing OR deprescription)". All studies reporting a deprescribing intervention for antidepressant medication, regardless of the study design, have been included. Studies that did not report antidepressant drug deprescription interventions and non-English-language papers have been excluded.

RESULTS

From the literature search, a total of 230 articles have been extracted. Applying the exclusion criteria, 26 articles have been considered eligible. Most of the analyzed studies (16, 61%) have been carried out in the real world, 3 (11%) were RCTs, 5 (19%) were qualitative studies, in particular expert opinions, 1 (4%) was a literature review, and 1 (4%) was a post-trial observational follow-up of an RCT. In 8 out of 26 studies (31%), the analyzed antidepressants have been specified: 2 (8%) focused on anticholinergics, 2 (8%) on SSRIs, 3 (11%) on tricyclic antidepressants, and 1 (4%) on esketamine. Nineteen out of 26 studies (73%) did not stratify antidepressants by therapeutic class. The sample sizes analyzed in the studies ranged from a minimum of 4 patients to a maximum of 113,909, and 12 studies included geriatric age as an inclusion criterion. A patient's therapy review has been the main deprescribing intervention, and it has been identified in 14 (54%) articles. Interventions have been carried out by clinicians in 4 (15%) studies, general practitioners in 5 (19%) studies, nurses in 2 (8%) studies, pharmacists in 4 (15%) studies, multidisciplinary teams in 10 (38%) studies, and patients in 1 (4%) study.

CONCLUSIONS

From the literature review, it emerged that there is no clear evidence useful to support clinicians in antidepressant deprescribing interventions.

Understanding Australian general practice patients' decisions to deprescribe antidepressants in the WiserAD trial: a realist informed approach

OBJECTIVES

To evaluate how an approach to antidepressant deprescribing works, for whom, and in what contexts by (1) examining the experiences and perceptions of the approach for antidepressant users, (2) identifying the mechanisms of the approach and (3) describing what contexts are associated with antidepressant tapering.

DESIGN

This mixed methods study was informed by the principles of realist evaluation and was conducted in the first 3 months of participation in the WiserAD randomised control trial.

SETTING

General practice, Victoria, Australia.

PARTICIPANTS

13 antidepressant users from general practice participating in the WiserAD trial for antidepressant deprescribing.

INTERVENTION

A patient-facing, web-based structured support tool that consists of a personalised tapering schedule, an action plan for managing withdrawal symptoms, a daily mood, sleep and activity tracker and mental health nurse support.

PRIMARY/SECONDARY OUTCOME MEASURES

The outcomes of the study were revealed on data analysis as per a realist evaluation approach which tests and refines an initial programme theory.

RESULTS

The contexts of learnt coping skills, knowledge and perceptions of antidepressants and feeling well were evident. Outcomes were intention to commence, initiation of deprescribing and successful completion of deprescribing. Key mechanisms for antidepressant deprescribing were (1) initiation of the deprescribing discussion; (2) patient self-efficacy; (3) provision of structured guidance; (4) coaching; (5) mood, sleep and activity tracking and (6) feelings of safety during the tapering period.

CONCLUSIONS

The WiserAD approach to antidepressant deprescribing supported participants to commence and/or complete tapering. The refined programme theory presents the WiserAD pragmatic framework for the application of antidepressant deprescribing in clinical practice.

Lessons from the Netherlands for Australia: cross-country comparison of trends in antidepressant dispensing 2013-2021 and contextual factors influencing prescribing

BACKGROUND

There is concern internationally about increasing antidepressant use. Most antidepressants are prescribed in general practice. The aim of this study was to compare trends in antidepressant dispensing in Australia and the Netherlands over the 9years from 2013 to 2021, and to explore reasons for differences.

METHODS

A convergent mixed methods study including analysis of publicly available antidepressant dispensing data obtained from Australia's Pharmaceutical Benefits Scheme and Repatriation Pharmaceutical Benefits Scheme and the Dutch Foundation for Pharmaceutical Statistics and a search of relevant literature to compare contextual factors influencing prescribing were undertaken.

RESULTS

In 2013, antidepressant dispensing rates in Australia were nearly twice as high as those in the Netherlands (82.5 versus 44.3DDD/1000/day) and increased to be more than twice as high by 2021 (115.6 versus 48.8DDD/1000/day). Antidepressant dispensing increased by 40% in Australia over the nine study years, but by only 10% in the Netherlands. Our scan of the literature confirms that while population factors, health system structure, and clinical guideline recommendations are largely consistent across the two countries, a multifaceted approach in the Netherlands involving improved access to non-pharmacological alternatives, initiatives targeting safer antidepressant prescribing, and tight regulation of pharmaceutical industry influence on prescribers, has successfully curtailed increasing antidepressant use.

CONCLUSIONS

Australia may learn from the Netherlands' approach to redress increasing antidepressant use.
