Evolution of benzodiazepine receptor agonist prescriptions in general practice: A registry-based study

Deprescribing benzodiazepine receptor agonists in older adults: a mixed-methods study to adapt the Canadian D-PRESCRIBE intervention to the Belgian community setting

OBJECTIVE

Guidelines recommend deprescribing benzodiazepine receptor agonists (BZRA) in older adults, yet implementation in clinical practice remains limited. Adapting effective, evidence-based interventions to a new context is a resource-saving strategy. In Canada, the D-PRESCRIBE intervention comprised a patient educational brochure and a pharmaceutical opinion inviting physicians to revise BZRA prescribing and consider safer alternatives. Due to its effectiveness on BZRA deprescribing among Canadian older adults, we aimed to adapt the D-PRESCRIBE intervention to the Belgian community setting.

DESIGN

Recommendations from the ADAPT guidance, that provides a systematic approach for adapting interventions to new contexts, were followed. We conducted a mixed-methods study that comprised (1) group discussions and cognitive interviews to assess the acceptability and need for adaptation of the intervention's components and (2) a survey on the adapted pharmaceutical opinion. A research committee involving stakeholders' representatives decided on the adaptations, respecting the core functions of both tools. Changes in intervention components were reported following the Model for Adaptation Design and Impact framework.

SETTING

Belgian French-speaking community setting.

PARTICIPANTS

Six older adults (≥65 years), six general practitioners (GPs) and seven pharmacists participated in the group discussions or interviews. 46 GPs and 91 pharmacists responded to the survey.

RESULTS

Participants welcomed the brochure positively. Still, some changes in the vocabulary, wording, photos and icons were made for several purposes including making the patient feel concerned about the brochure and softening the use of fear. The pharmaceutical opinion aroused mixed perceptions. Its name, layout and content were adapted to enhance its acceptability and fit with our healthcare system, practices and national guidelines. The survey highlighted several enablers and barriers to its use from the perspectives of GP and pharmacist.

CONCLUSIONS

The Canadian D-PRESCRIBE intervention was adapted to the Belgian setting following a thorough and transparent process. Its feasibility will be tested in a future pilot study (NCT:05929417).

Model-based disease mapping using primary care registry data

BACKGROUND

Spatial modeling of disease risk using primary care registry data is promising for public health surveillance. However, it remains unclear to which extent challenges such as spatially disproportionate sampling and practice-specific reporting variation affect statistical inference.

METHODS

Using lower respiratory tract infection data from the INTEGO registry, modeled with a logistic model incorporating patient characteristics, a spatially structured random effect at municipality level, and an unstructured random effect at practice level, we conducted a case and simulation study to assess the impact of these challenges on spatial trend estimation.

RESULTS

Even with spatial imbalance and practice-specific reporting variation, the model performed well. Performance improved with increasing spatial sample balance and decreasing practice-specific variation.

CONCLUSION

Our findings indicate that, with correction for reporting efforts, primary care registries are valuable for spatial trend estimation. The diversity of patient locations within practice populations plays an important role.

Professionals' treatment goals for long-term benzodiazepine and Z-drugs management: a qualitative study

BACKGROUND

Benzodiazepines and Z-drugs (BZD/Z) are frequently prescribed for longer than recommended. Through their interactions with patients taking BZD/Z, primary care and mental health professionals play a key role in the management of this medication.

AIM

To explore how primary care and mental health care professionals set treatment goals with users of long-term BZD/Z.

DESIGN & SETTING

A qualitative study using semi-structured interviews with professionals from mental health, addiction care, and primary care practices in Belgium.

METHOD

Semi-structured interviews were conducted, online and in person, with 24 professionals working in mental health and primary care. Inductive thematic content analysis was performed.

RESULTS

Seven themes were identified from the analysis. Professionals tended not to use the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) standard to diagnose a BZD/Z substance use disorder. They described criteria based on their experience. They identified diverse types of patients that influence their choice of treatment goals. Professionals appeared to position themselves according to their own treatment goals for their patients, either by promoting the goal of abstinence or harm reduction. Some of them reported feeling trapped into continuing to prescribe and considered BZD/Z withdrawal to be difficult. Some were afraid to engage in a conversation that might break the bond of trust with the patient. Few professionals mentioned patient participation in the treatment goal setting. They asked for targeted withdrawal recommendations, perceiving the current recommendations to be too broad.

CONCLUSION

Whether primary care or mental health care professionals are more in favour of a total abstinence or a harm reduction approach to BZD/Z, professionals should be guided towards greater patient participation in setting and evaluating goals with patients taking BZD/Z.

Assessing mental health from registry data: What is the best proxy?

OBJECTIVE

Medical registries frequently underestimate the prevalence of health problems compared with surveys. This study aimed to determine the registry variables that can serve as a proxy for variables studied in a mental health survey.

MATERIALS AND METHODS

Prevalences of depressive symptoms, anxiety and psychoactive medication use from the 2018 Belgian Health Interview Survey (HIS) were compared with same-year prevalences from INTEGO, a Belgian primary care registry. Participants aged 15 and above were included. We assessed correlation using Spearman's rho (SR), and agreement using the intraclass correlation coefficient (ICC). We also calculated the limits of agreement (LOAs) for each comparison. HIS questions about depressive symptoms, anxiety and psychoactive medication use were compared with the following variables from INTEGO: symptom codes, diagnosis codes, free text, antidepressant/benzodiazepine prescriptions and the combinations symptom + diagnosis codes and symptom + diagnosis codes + free text, wherever relevant.

RESULTS AND DISCUSSION

Correlation between the HIS and INTEGO was generally high, except for anxiety. Agreement ranged from fair to poor, but increased when combining certain variables, by including free text, or by increasing the prescription frequency to resemble chronic use. Agreement remained poor when comparing questions about anxiety. Prevalences from INTEGO were mostly underestimates.

CONCLUSION

The external validity of medical registries can be poor, especially compared with survey data. A considerate choice of variables and prescription chronicity is needed to accurately use a registry as a surveillance tool for mental health.

Reducing long-term use of benzodiazepine receptor agonists: In-depth interview study with primary care stakeholders

AIMS

To increase our understanding of which factors contribute to long-term benzodiazepine receptor agonist (BZRA) use for insomnia in primary care, from a patients', general practitioners' (GP) and pharmacists' perspective.

DESIGN

Qualitative research following a grounded theory approach.

SETTING

Primary care in Belgium.

PARTICIPANTS

Twenty-four participants were interviewed, including nine patients, six GPs and nine pharmacists.

MEASUREMENTS

In-depth, semistructured interviews with iterative cycles of data collection and analysis. Transcripts were analysed using the framework method. Thematic findings were interpreted in the context of the Theoretical Domains Framework.

FINDINGS

A reflexive relation was identified between views about hypnotic use at the level of society, healthcare and patients. Behaviour change appeared to depend strongly on context and social influence, including a need for supporting relationships by all stakeholders. Six key messages captured factors that contribute to long-term BZRA use for insomnia in primary care: societal beliefs as a game changer, the opportunity of nonpharmacological treatment, collaborative primary care, patient-centred goals, informed consent and self-management.

CONCLUSIONS

Long-term BZRA use for insomnia is a complex and multifaceted public health problem that is not adequately addressed in primary care at this time. Although primary care professionals in this study found discontinuation of long-term BZRA use relevant to the patient's health, many organisational and personal barriers were reported. Moreover, the current social and healthcare context is not empowering patients and professionals to reduce long-term BZRA use for insomnia. Specifically, for primary care, all stakeholders reported the need for a nonmedicalised relationship between the patient and GP to lower prescribing rates.

PATIENT OR PUBLIC CONTRIBUTION

The Flemish Patient Platform, a patient representative organisation, assisted with recruitment by launching a call for participants in their newsletter and volunteered to disseminate the results. The call for recruitment was also published online in social media groups regarding insomnia and via posters in public pharmacies. Patients or public were not involved in designing or conducting the interview study.

From prescribing dilemma to knowledge in practice: The ontological politics of benzodiazepines and Z-drugs

The discrepancy between official guidelines and clinical practice is hardly more pronounced than in the case of benzodiazepines and Z-drugs, also known as benzodiazepine receptor agonists (BZRA). Using social-constructionist positioning theory, we unravel how health care professionals deal with the dilemma of prescribing this medication. Our results reveal a prescribing spectrum that is discursively organised around four different storylines used by professionals. The storylines are organised along three axes that are related to a) prescribers' opinions on prescribing and the negotiation of the related risks, b) the power dynamics between provider and patient in the prescribing process and c) the rhetorical use of arguments. The discerned storylines allow us to explore the emotional and moral side of prescribing and demarcate clinical mindlines -internalised tacit guidelines-that professionals adhere to when they prescribe. By relying on Annemarie Mol's conceptualisation of ontological politics, we explain how these storylines enact multiple versions of this class of medication and justify seemingly contradictory prescribing practices.

"At the time I only wanted to relieve stress": Exploring motivation for behaviour change in long-term hypnotic users

Background

Motivating patients to discontinue long-term benzodiazepine receptor agonist (BZRA) use for insomnia remains an important challenge in primary care because of the medication's unfavourable risk-benefit profile. Previous studies have shown that understanding the complexity of patients' motivation is crucial to the primary care physician for providing effective interventions efficiently. Theoretical frameworks about behaviour change show that motivation is a multi-layered concept that interacts with other concepts, which aligns with a holistic perspective or implementation of the biopsychosocial model.

Aim

Exploring primary care patients' views and ideas on what factors helped or hindered them in discontinuing long-term BZRA use, in relation to motivation as conceptualised in the Behaviour Change Wheel, and associated domains of the Theoretical Domains Framework.

Design and setting

A qualitative study with semi-structured interviews in primary care in Belgium between September 2020 and March 2021.

Method

Eighteen interviews with long-term hypnotic users were audio recorded, transcribed and thematically analyzed, using the Framework Method.

Results

The success of discontinuation interventions does not solely rely on patients' spontaneous sense of striving for improvement. Reinforcement and identity were found to be important domains for motivation. Beliefs about personal capabilities, and about consequences of both BZRA intake and discontinuation, differed between previous and current users.

Conclusion

Motivation is a multi-layered concept which is not fixed in time. Patient empowerment and goal setting could help long-term BZRA users to lower their intake. As well as public health interventions that might change social attitudes towards the use of hypnotic medication.

Blended care to discontinue BZRA use in patients with chronic insomnia disorder: a pragmatic cluster randomized controlled trial in primary care

STUDY OBJECTIVES

International guidelines recommend using benzodiazepine receptor agonists (BZRA) for maximally four weeks. Nevertheless, long-term use for chronic insomnia disorder remains a common practice. This study aimed to test the effectiveness of blended care for discontinuing long-term BZRA use in general practice.

METHODS

A pragmatic cluster randomized controlled superiority trial compared blended care to usual care through urine toxicology screening. In the intervention, care by the general practitioner (GP) was complemented by an interactive e-learning program, based on cognitive behavioral therapy for insomnia. Adults using BZRA daily for minimally six months were eligible. Participants were clustered at the level of the GP surgery for allocation (1:1). Effectiveness was measured as the proportion of patients who had discontinued at one-year follow-up. Data analysis followed intention-to-treat principles.

RESULTS

In total, 916 patients in 86 clusters, represented by 99 GPs, were randomized. Primary outcome data was obtained from 727 patients (79%). At one-year follow-up, 82 patients (18%) in blended care, compared to 91 patients (20%) in usual care, had discontinued. There was no statistically significant effect for the intervention (OR: 0·924; 95% CI: 0·60, 1·43). No adverse events were reported to the research team.

CONCLUSIONS

The findings did not support the superiority of blended care over usual care. Both strategies showed clinical effectiveness, with an average of 19% of patients having discontinued at one-year follow-up. Further research is important to study the effect of structurally implementing digital interventions in general practice.
