Abstract 4140180: The Effect of Benzodiazepine Use in Patients with Atrial Fibrillation and Obstructive Sleep Apnea

Circulation, Volume 150, Issue Suppl_1, Page A4140180-A4140180, November 12, 2024. Introduction:Sleep apnea is a common sleep disorder that can worsen atrial fibrillation(AF) prognosis. Benzodiazepines(BZD) are commonly prescribed for insomnia, which often accompanies sleep apnea. However, BZDs have been associated with worsening of sleep apnea due to respiratory depression, pharyngeal muscle relaxation, and increase of arousal threshold, which all may lead to prolonged hypoxia. There is little research on the effect of BZD use in AF patients with sleep apnea. Therefore, the objective of this study is to investigate the effects of BZD usage on outcomes in the AF population with sleep apnea.Methods:Data from patients with AF and sleep apnea seen at Tulane Medical Center between 2010 and 2019 was obtained from Research Action for Health Network(REACHnet), a Clinical Research Network in PCORnet®. Patients with AF and sleep apnea were divided between those with a prescription of BZD and those without BZD. These two groups were compared using the Kaplan-Meier method for time-to outcome for all-cause mortality, ischemic stroke, myocardial infarction(MI), and hospitalizations in the five years following their AF diagnosis. Cox regression analysis was used to investigate proportional hazards and control for demographics, comorbidities, and medication use.Results:There were 524 total patients included with AF and sleep apnea. Of these, 413(78.8%) were not prescribed BZDs, while 111(21.1%) were taking BZDs. Use of BZDs was associated with worse outcomes. In the no BZD and the BZD group over the 5 years following AF diagnosis, the rate of mortality was 6.1% and 12.6%(p

Feasibility of a theory-based intervention towards benzodiazepine deprescribing in Belgian nursing homes: protocol of the END-IT NH cluster-randomised controlled trial

Introduction
Despite several calls to deprescribe benzodiazepine receptor agonists (BZRA) in older adults, their use among nursing home residents (NHRs) remains high. Therefore, we developed an intervention targeting general practitioners’ and healthcare professionals’ behaviours regarding BZRA deprescribing in nursing homes (NHs): The END-IT NH (bENzodiazepines Deprescribing InTerventions Nursing homes) 6-component intervention. Before moving on to a large-scale effectiveness and cost-effectiveness evaluation, this feasibility study aims at: (1) assessing the feasibility of the intervention implementation in NHs, (2) assessing the feasibility of conducting a larger-scale evaluation, in terms of recruitment and data collection and (3) conducting an exploratory cost-effectiveness evaluation.

Methods and analysis
We will conduct a cluster-randomised controlled trial in a sample of 6 NHs, with 10–15 NHRs included per NHs. Four NHs will be randomised into the intervention group, and two NHs will deliver usual care (control group). Data collection will occur at baseline, 3, and 6 months (study end). We will collect information to explore implementation fidelity, mechanisms of impact and contextual factors at patient-level, NH-level and healthcare professional-level, using both quantitative and qualitative measures. The feasibility of the study conduction will be assessed by measuring recruitment and attrition rates and completeness of data collection. An exploratory cost-effectiveness evaluation will be conducted based on quality of life and healthcare use and cost data.

Ethics and dissemination
This study protocol received approval from the ethical committee of CHU UCL Namur on the 20 June 2023. All data are confidential and will be anonymised prior to analysis. De-identified data will be shared on a data depository with a 2-year embargo. The results of the study will be disseminated through a scientific paper and will be communicated to local stakeholders and policymakers through a local symposium.

Trial registration number
NCT05929443.

Benzodiazepine Utilization in Ischemic Stroke Survivors: Analyzing Initial Excess Supply and Longitudinal Trends

Stroke, Ahead of Print. BACKGROUND:Benzodiazepines are commonly prescribed for post-acute ischemic stroke for anxiety, insomnia, and agitation. While guidelines discourage use in those aged ≥65 years, little is known about prescription patterns at the national level.METHODS:We analyzed a 20% sample of US Medicare claims from April 1, 2013, to September 30, 2021. We selected beneficiaries aged ≥65 years discharged alive following an acute ischemic stroke who had traditional Medicare coverage and 6 months’ prior enrollment in Parts A (hospital insurance), B (Medical insurance), and D (drug coverage). We excluded those with prior benzodiazepine prescriptions, self-discharges, or discharge to skilled nursing facilities. We examined demographics, comorbidities, first prescription days’ supply, cumulative incidences of benzodiazepine first prescription fills within 90 days after discharge, and geographic and yearly trends.RESULTS:We included 126 050 beneficiaries with a mean age of 78 years (SD, 8); 54% were female and 82% were White. Within 90 days, 6127 (4.9%) initiated a benzodiazepine. Among new prescriptions, lorazepam (40%) and alprazolam (33%) were the most prescribed. Most (76%) of first fills had a day’s supply over 7 days and 55% between 15 and 30 days. Female initiation rates were higher (5.5% [95% CI, 5.3–5.7]) than male initiation rates (3.8% [95% CI, 3.6%–3.9%]). Rates were highest in the southeast (5.1% [95% CI, 4.8%–5.3%]) and lowest in the midwest (4.0% [95% CI, 3.8%–4.3%]), with a modest nationwide initiation decline from 2013 to 2021 (cumulative incidence difference, 1.6%).CONCLUSIONS:Despite a gradual decline in benzodiazepine initiation from 2013 to 2021, we noted excessive supplies in prescriptions post-acute ischemic stroke discharge, underscoring the need for improved policies.

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).

Association between benzodiazepine coprescription and mortality in people on opioid replacement therapy: a population-based cohort study

Objective
To investigate the association between opioid replacement therapy (ORT) and benzodiazepine (BZD) coprescription and all-cause mortality compared with the prescription of ORT alone.

Design
Population-based cohort study.

Setting
Scotland, UK.

Participants
Participants were people prescribed ORT between January 2010 and end of December 2020 aged 18 years or above.

Main outcome measures
All-cause mortality, drug-related deaths and non-drug related deaths.

Secondary outcome
ORT continuous treatment duration.

Analysis
Cox regression with time-varying covariates.

Results
During follow-up, 5776 of 46 899 participants died: 1398 while on coprescription and 4378 while on ORT only. The mortality per 100 person years was 3.11 during coprescription and 2.34 on ORT only. The adjusted HR for all-cause mortality was 1.17 (1.10 to 1.24). The adjusted HR for drug-related death was 1.14 (95% CI, 1.04 to 1.24) and the hazard for death not classified as drug-related was 1.19 (95% CI, 1.09 to 1.30).

Conclusion
Coprescription of BZDs in ORT was associated with an increased risk of all-cause mortality, although with a small effect size than the international literature. Coprescribing was also associated with longer retention in treatment. Risk from BZD coprescription needs to be balanced against the risk from illicit BZDs and unplanned treatment discontinuation. A randomised controlled trial is urgently needed to provide a clear clinical direction.

Trial registration number
NCT04622995.
