Effectiveness of current treatment approaches for benzodiazepine discontinuation: a meta-analysis

Masked Taper With Behavioral Intervention for Discontinuation of Benzodiazepine Receptor Agonists: A Randomized Clinical Trial

Importance

Placebo effects are commonly observed in benzodiazepine receptor agonist hypnotic clinical trials. Clinical guidelines recommend discontinuing benzodiazepine receptor agonist hypnotics (particularly in older adults) and administering cognitive behavioral therapy for insomnia (CBTI) as first-line therapy for insomnia. It is unknown whether a novel intervention that masks the daily dose of benzodiazepine receptor agonist during tapering and augments CBTI with novel cognitive and behavioral exercises targeting placebo effect mechanisms improves benzodiazepine receptor agonist discontinuation.

Objective

To compare a masked benzodiazepine receptor agonist taper plus augmented CBTI vs an unmasked taper plus standard CBTI.

Design, Setting, and Participants

This randomized clinical trial conducted at an academic medical center and a Department of Veterans Affairs medical center included adults aged 55 years or older who had used lorazepam, alprazolam, clonazepam, temazepam, and/or zolpidem for current or prior insomnia, at doses of less than 8-mg diazepam-equivalent 2 or more nights per week for at least 3 months. Data were collected between December 2018 and November 2023. Data analyses were conducted between November 2023 and July 2024.

Interventions

Masked taper plus cognitive behavioral therapy-augmented program (MTcap); standard CBTI plus supervised (unmasked) gradual taper (SGT).

Main Outcomes and Measures

The primary efficacy outcome was percentage achieving benzodiazepine receptor agonist discontinuation 6 months after treatment ended (6-month; intention-to-treat) measured with 7-day self-reported medication logs and for a subset, urine tests. Secondary outcomes were Insomnia Severity Index scores at 1 week posttreatment and 6 months posttreatment, percentage of participants that have discontinued benzodiazepine receptor agonist use at 1 week posttreatment, and benzodiazepine receptor agonist dose and the Dysfunctional Beliefs About Sleep-Medication subscale at 1 week and 6 months posttreatment.

Results

Of 338 participants who underwent in-depth screening, 188 participants (mean [SD] age, 69.8 [8.3] years, 123 male [65.4%] and 65 female [35.6%]) were randomly assigned to MTcap (n = 92) or SGT (n = 96). Compared with SGT, MTcap resulted in greater benzodiazepine receptor agonist discontinuation at 6 months (MTcap = 64 [73.4%], SGT = 52 [58.6%]; odds ratio [OR], 1.95; 95% CI 1.03-3.70; P = .04) and 1 week posttreatment (MTcap = 76 [88.4%], SGT =  62 [67.4%]; OR, 3.68; 95% CI, 1.67-8.12; P = .001) and reduced frequency of benzodiazepine receptor agonist use (nights/week) at 1 week posttreatment (-1.31; 95% CI, -2.05 to -0.57; P < .001). Insomnia Severity Index improved with no significant between-group difference at follow-up (baseline to 1 week posttreatment, 1.38; P = .16; baseline to 6 months, 0.16; P = .88).

Conclusions and Relevance

This randomized clinical trial found that a program combining masked tapering with novel cognitive and behavioral exercises targeting placebo mechanisms improved the percentage of long-term benzodiazepine receptor agonist discontinuation compared with standard CBTI plus an unmasked taper.

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.

Treating Benzodiazepine Withdrawal in a Bridge Clinic

BACKGROUND

Benzodiazepine-involved overdose deaths are rising, driven by increasing use of nonprescribed benzodiazepine pills. For patients who wish to stop nonprescribed benzodiazepine use, rapid inpatient tapers are typically the only option to treat benzodiazepine withdrawal. Substance use disorder bridge clinics can provide the high-touch care needed to manage outpatient benzodiazepine tapers in patients at high risk due to other substance use disorders.

OBJECTIVE

Describe the implementation and short-term outcomes of an outpatient benzodiazepine taper protocol to treat benzodiazepine withdrawal in a substance use disorder bridge clinic.

METHODS

The clinical team developed a 4- to 6-week intensive outpatient taper protocol using diazepam. Patients with benzodiazepine use disorder were eligible if they had benzodiazepine withdrawal, lacked a prescriber, wanted to stop benzodiazepines completely, and agreed to daily visits. For patients who initiated a taper between April 2021 and December 2022, we evaluated the proportion of patients who completed a taper (i.e., tapered to a last prescribed dose of diazepam 10 mg/d or less); likelihood of remaining on the taper over time; and seizure, overdose, or death documented at the study institution during or within 1 month of taper completion or discontinuation. Other secondary outcomes included HIV testing and prevention, hepatitis C testing, and referrals to recovery coaching or psychiatry.

RESULTS

Fifty-four patients initiated a total of 60 benzodiazepine tapers. The population was mostly male (61%) and non-Hispanic White (85%). Nearly all patients had opioid use disorder (96%), and most (80%) were taking methadone or buprenorphine for opioid use disorder before starting the taper. Patients reported using multiple substances in addition to benzodiazepines, most commonly fentanyl (75%), followed by cocaine (41%) and methamphetamine (21%). Fourteen patients (23%) completed a taper with a median duration of 34 days (IQR 27.8-43.5). Most tapers were stopped when the patient was lost to follow-up (57%), or the team recommended inpatient care (18%). Two patients had a seizure, and 4 had a presumed opioid-involved overdose during or within 1 month after the last taper visit, all individuals who did not complete a taper. No deaths occurred during or within 1 month of taper completion or discontinuation. Challenges included frequent loss to follow-up in the setting of other unstable substance use. Patients received other high-priority care during the taper including HIV testing (32%), PrEP initiation (6.7%), hepatitis C testing (30%), and referrals to recovery coaches (18%) and psychiatry (6.7%).

CONCLUSIONS

Managing benzodiazepine withdrawal with a 4- to 6-week intensive outpatient taper in patients with benzodiazepine and opioid use disorders is challenging. More work is needed to refine patient selection, balance safety risks with feasibility, and study long-term, patient-centered outcomes.

Deprescribing interventions in older adults: An overview of systematic reviews

OBJECTIVE

The growing deprescribing field is challenged by a lack of consensus around evidence and knowledge gaps. The objective of this overview of systematic reviews was to summarize the review evidence for deprescribing interventions in older adults.

METHODS

11 databases were searched from 1st January 2005 to 16th March 2023 to identify systematic reviews. We summarized and synthesized the results in two steps. Step 1 summarized results reported by the included reviews (including meta-analyses). Step 2 involved a narrative synthesis of review results by outcome. Outcomes included medication-related outcomes (e.g., medication reduction, medication appropriateness) or twelve other outcomes (e.g., mortality, adverse events). We summarized outcomes according to subgroups (patient characteristics, intervention type and setting) when direct comparisons were available within the reviews. The quality of included reviews was assessed using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2).

RESULTS

We retrieved 3,228 unique citations and assessed 135 full-text articles for eligibility. Forty-eight reviews (encompassing 17 meta-analyses) were included. Thirty-one of the 48 reviews had a general deprescribing focus, 16 focused on specific medication classes or therapeutic categories and one included both. Twelve of 17 reviews meta-analyzed medication-related outcomes (33 outcomes: 25 favored the intervention, 7 found no difference, 1 favored the comparison). The narrative synthesis indicated that most interventions resulted in some evidence of medication reduction while for other outcomes we found primarily no evidence of an effect. Results were mixed for adverse events and few reviews reported adverse drug withdrawal events. Limited information was available for people with dementia, frailty and multimorbidity. All but one review scored low or critically low on quality assessment.

CONCLUSION

Deprescribing interventions likely resulted in medication reduction but evidence on other outcomes, in particular relating to adverse events, or in vulnerable subgroups or settings was limited. Future research should focus on designing studies powered to examine harms, patient-reported outcomes, and effects on vulnerable subgroups.

Deprescribing: An umbrella review

This umbrella review examined systematic reviews of deprescribing studies by characteristics of intervention, population, medicine, and setting. Clinical and humanistic outcomes, barriers and facilitators, and tools for deprescribing are presented. The Medline database was used. The search was limited to systematic reviews and meta-analyses published in English up to April 2022. Reviews reporting deprescribing were included, while those where depre-scribing was not planned and supervised by a healthcare professional were excluded. A total of 94 systematic reviews (23 meta--analyses) were included. Most explored clinical or humanistic outcomes (70/94, 74 %); less explored attitudes, facilitators, or barriers to deprescribing (17/94, 18 %); few focused on tools (8/94, 8.5 %). Reviews assessing clinical or humanistic outcomes were divided into two groups: reviews with deprescribing intervention trials (39/70, 56 %; 16 reviewing specific deprescribing interventions and 23 broad medication optimisation interventions), and reviews with medication cessation trials (31/70, 44 %). Deprescribing was feasible and resulted in a reduction of inappropriate medications in reviews with deprescribing intervention trials. Complex broad medication optimisation interventions were shown to reduce hospitalisation, falls, and mortality rates. In reviews of medication cessation trials, a higher frequency of adverse drug withdrawal events underscores the importance of prioritizing patient safety and exercising caution when stopping medicines, particularly in patients with clear and appropriate indications.

A retrospective clinical practice study comparing the usefulness of dual-orexin receptor antagonists and a melatonin receptor agonist in patients switching from long-term benzodiazepine receptor agonists

STUDY OBJECTIVES

Although novel hypnotics have recently emerged, there are currently no data comparing the clinical potency of benzodiazepine receptor agonists (BZRAs) and novel hypnotics, or the effectiveness of different methods of switching between them. This study examined how novel hypnotics might help reduce BZRA use in real-world practice.

METHODS

289 patients with psychiatric disorders who took BZRAs for over 1 year before switching to either of 2 dual-orexin receptor antagonists (DORAs; suvorexant [SUV] or lemborexant [LEM]) or a melatonin receptor agonist (ramelteon [RMT]) were enrolled. We collected data on BZRAs at baseline and 3 months after commencement of SUV/LEM/RMT.

RESULTS

Significant reductions in BZRAs were observed for all 3 agents: -4.10, -2.80, and -1.65 mg in diazepam-equivalent doses in the SUV, LEM, and RMT groups, respectively. Dose reduction was significantly greater in the DORA than the RMT group (F = 15.053, P < .001). Within the DORA group, dose reduction was significantly greater in patients taking SUV than those taking LEM (F = 4.337, P = .043). The switching success rate did not differ among the switching methods for any of the hypnotics.

CONCLUSIONS

The reduction rate of BZRAs achieved by the switch fell into their equivalent-potency range estimated from clinical trials. The results suggest that DORAs can replace approximately 1 tablet of a BZRA. The difference in dose reduction between DORAs and RMT reflected the greater sleeping potency of the DORAs, whereas that between SUV and LEM might have reflected patient backgrounds: patients taking LEM may have been more strongly dependent on BZRAs.

The effect of lemborexant on insomnia in patients with psychiatric disorders: Detailed evaluation using the Athens Insomnia Scale

Aim

Chronic insomnia disorder is common and associated with reduced quality of life. Benzodiazepine hypnotics are commonly prescribed for insomnia, but have potential side effects such as concentration impairment, somnolence, and dependence. Lemborexant (LEM) is an orexin receptor antagonist considered to have fewer side effects than benzodiazepine hypnotics. This study evaluated the effect of LEM on sleep in detail and examined whether benzodiazepine hypnotics can be gradually tapered by adding LEM.

Methods

We retrospectively examined the effectiveness of LEM in 28 outpatients with insomnia. Insomnia symptoms were assessed using the Athens Insomnia Scale (AIS) before and after LEM administration. We also attempted to taper benzodiazepine hypnotics and assessed benzodiazepine dose using diazepam equivalents for some patients taking benzodiazepine hypnotics. Wilcoxon's signed-rank test was used for statistical analysis.

Results

The mean AIS score was significantly improved after LEM treatment (8.7 ± 5.2 vs. 3.8 ± 3.3; P < 0.01). Among the AIS subitems, significant improvement was observed for six items: sleep induction, awakenings during the night, sleep quality, well-being, functioning capacity, and sleepiness during the day. The mean benzodiazepine dose was significantly lower after LEM treatment (4.6 ± 5.0 mg vs. 2.1 ± 3.3 mg; P < 0.01).

Conclusions

This study indicated the potential of LEM for improving insomnia and reducing benzodiazepine dose.

Development of an intervention to manage benzodiazepine dependence and high-risk use in the context of escalating drug related deaths in Scotland: an application of the MRC framework

BACKGROUND

Scotland has the highest rate of drug related deaths (DRD) in Europe. These are deaths in people who use drugs such as heroin, cocaine, benzodiazepines and gabapentinoids. It is a feature of deaths in Scotland that people use combinations of drugs which increases the chance of a DRD. Many deaths involve 'street' benzodiazepines, especially a drug called etizolam. Many of the 'street' benzodiazepines are not licensed in the UK so come from illegal sources. People who use opiates can be prescribed a safer replacement medication (e.g., methadone). While guidance on management of benzodiazepines use highlights that there is little evidence to support replacement prescribing, practice and evidence are emerging.

AIM

To develop an intervention to address 'street' benzodiazepines use in people who also use opiates.

METHODS

The MRC Framework for Complex Interventions was used to inform research design. Co-production of the intervention was achieved through three online workshops with clinicians, academics working in the area of substance use, and people with lived experience (PWLE). Each workshop was followed by a PWLE group meeting. Outputs from workshops were discussed and refined by the PWLE group and then further explored at the next workshop.

RESULTS

After these six sessions, a finalised logic model for the intervention was successfully achieved that was acceptable to clinicians and PWLE. Key components of the intervention were: prescribing of diazepam; anxiety management, sleep, and pain; and harm reduction resources (locked box and a range of tips), personal safety conversations, as well as a virtual learning environment.

CONCLUSION

A co-produced intervention was developed for next stage clinical feasibility testing.

Reduction of Sleep Medications via a Combined Digital Insomnia and Pharmacist-Led Deprescribing Intervention: Protocol for a Feasibility Trial

BACKGROUND

Chronic insomnia is one of the most common health problems among veterans and negatively impacts their health, function, and quality of life. Although cognitive behavioral therapy for insomnia (CBT-I) is the first-line recommended treatment, sedative-hypnotic medications remain the most common. Sedative-hypnotics, however, have mixed effectiveness, are frequently prescribed longer than recommended, and are associated with numerous risks and adverse effects that negatively impact veteran function. Meeting the treatment needs of veterans impacted by insomnia requires delivering gold standard behavioral care, like CBT-I, and the reduction of sedative-hypnotics through innovative methods.

OBJECTIVE

The objective of this feasibility clinical trial is to test a digital CBT-I approach combined with deprescribing to improve the success of sedative-hypnotic reduction among veterans. The intervention combines Noctem Health Clinician Operated Assistive Sleep Technology (COAST), an effective and efficient, scalable, and adaptable digital platform to deliver CBT-I, with clinical pharmacy practitioner (CPP)-led deprescribing of sedative-hypnotic medications.

METHODS

In this nonrandomized single-group clinical trial, 50 veterans will be recruited and enrolled to receive CBT-I delivered via Noctem COAST and CPP-led deprescribing for up to 12 weeks. Assessments will occur at baseline, posttreatment, and 3-month follow-up. The aims are to (1) assess the feasibility of recruiting veterans with chronic sedative-hypnotic use to participate in the combined intervention, (2) evaluate veterans' acceptability and usability of the COAST platform, and (3) measure changes in veterans' sleep, sedative-hypnotic use, and function at baseline, posttreatment, and 3-month follow-up.

RESULTS

The institutional review board approved the study in October 2021 and the trial was initiated in May 2022. Recruitment and data collection began in September 2022 and is anticipated to be completed in April 2024. Aim 1 will be measured by tracking the response to a mail-centric recruitment approach using electronic medical records to identify potentially eligible veterans based on sedative-hypnotic use. Aim 2 will be measured using the Post-Study System Usability Questionnaire, assessing overall usability as well as system usefulness, information quality, and interface quality. Aim 3 will use the Insomnia Severity Index and sleep diaries to measure change in insomnia outcomes, the Patient-Reported Outcome Measurement Information System Profile to measure change in physical function, anxiety, depression, fatigue, sleep disturbance, participation in social roles, pain, cognitive function, and self-reported sedative-hypnotic use to measure change in dose and frequency of use.

CONCLUSIONS

Findings will inform the utility of a combined digital CBT-I and CPP-led deprescribing intervention and the development of an adequately powered clinical trial to test the effectiveness in a diverse sample of veterans. Further, findings will help inform potential new approaches to deliver care and improve access to care for veterans with insomnia, many of whom use sedative-hypnotics that may be ineffective and increase the risk for negative outcomes.

"Stabilise-reduce, stabilise-reduce": A survey of the common practices of deprescribing services and recommendations for future services

BACKGROUND

Public Health England recently called for the establishment of services to help people to safely stop prescribed drugs associated with dependence and withdrawal, including benzodiazepines, z-drugs, antidepressants, gabapentinoids and opioids. NICE identified a lack of knowledge about the best model for such service delivery. Therefore, we performed a global survey of existing deprescribing services to identify common practices and inform service development.

METHODS

We identified existing deprescribing services and interviewed key personnel in these services using an interview co-produced with researchers with lived experience of withdrawal. We summarised the common practices of the services and analysed the interviews using a rapid form of qualitative framework analysis.

RESULTS

Thirteen deprescribing services were included (8 UK, 5 from other countries). The common practices in the services were: gradual tapering of medications often over more than a year, and reductions made in a broadly hyperbolic manner (smaller reductions as total dose became lower). Reductions were individualised so that withdrawal symptoms remained tolerable, with the patient leading this decision-making in most services. Support and reassurance were provided throughout the process, sometimes by means of telephone support lines. Psychosocial support for the management of underlying conditions (e.g. CBT, counselling) were provided by the service or through referral. Lived experience was often embedded in services through founders, hiring criteria, peer support and sources of information to guide tapering.

CONCLUSION

We found many common practices across existing deprescribing services around the world. We suggest that these ingredients are included in commissioning guidance of future services and suggest directions for further research to clarify best practice.

Feasibility and effectiveness of deprescribing benzodiazepines and Z-drugs: systematic review and meta-analysis

BACKGROUND AND AIMS

A total of 2.4 million adults in England were dispensed a benzodiazepine or Z-drug (BZRA) in 2017/18, and more than 250 000 patients in the UK take BZRAs beyond the recommended duration. Deprescribing is a clinician-guided process of withdrawing inappropriate drugs. This review aimed to evaluate the evidence base supporting the feasibility and clinical effectiveness of all forms of deprescribing initiatives used to discontinue long-term (≥ 4 weeks) BZRAs.

METHOD

Systematic review of randomized controlled trials evaluating BZRAs deprescribing among adults in community, primary or outpatient settings. MEDLINE, Embase and PsycINFO were searched from inception to February 2021. Primary outcomes were successful discontinuation in the short (< 4 weeks) or long term (≥ 4 weeks) and the occurrence of withdrawal symptoms, behavioural or psychological symptoms. Studies were categorized as pharmacological or non-pharmacological supported interventions. Study quality was assessed using the Cochrane risk-of-bias tool. Where appropriate, risk ratios (RRs), mean differences and 95% confidence intervals (CIs) were calculated, and Mantel-Haenszel methods using the random-effect meta-analysis was undertaken to calculate summary effect estimates.

RESULTS

Ten studies were included (n = 1431 participants). Heterogeneity in study design and effect was observed. Benzodiazepines were successfully deprescribed when gradually tapered with non-pharmacological support compared with gradual tapering alone in the short term (n = 124; RR = 2.02; 95% CI = 1.41, 2.89) and long term (n = 123; RR = 2.45; 95% CI = 1.56, 3.85). Benzodiazepine deprescribing was more successful when supported by non-pharmacological methods versus routine care (n = 189; RR = 3.26; 95% CI = 2.36, 4.51). Quality of evidence reporting effectiveness was very low to low.

CONCLUSIONS

It may be feasible to deprescribe benzodiazepines depending on the process and support mechanisms employed.

Clinical management of withdrawal from benzodiazepine anxiolytic and hypnotic medications

Benzodiazepines continue to be prescribed widely in the management of patients with insomnia or anxiety disorders, despite the availability and acceptability of alternative pharmacological and psychological treatments. Many patients will experience adverse effects during treatment and considerable distress when the dosage is reduced and stopped. Management of benzodiazepine withdrawal includes measures to prevent the development of dependence, careful attention to underlying medical conditions, medication consolidation and gradual dosage reduction, accompanying psychological interventions, occasional prescription of concomitant medication, and relapse prevention with on-going support to address psychosocial stressors. There are needs for easier patient access to services with refined expertise and for further research to optimise strategies for preventing dependence and facilitating withdrawal.

Evaluation of a multicomponent intervention consisting of education and feedback to reduce benzodiazepine prescriptions by general practitioners: The BENZORED hybrid type 1 cluster randomized controlled trial

BACKGROUND

Current benzodiazepine (BZD) prescription guidelines recommend short-term use to minimize the risk of dependence, cognitive impairment, and falls and fractures. However, many clinicians overprescribe BZDs and chronic use by patients is common. There is limited evidence on the effectiveness of interventions delivered by general practitioners (GPs) on reducing prescriptions and long-term use of BZDs. We aimed to evaluate the effectiveness of a multicomponent intervention for GPs that seeks to reduce BZD prescriptions and the prevalence of long-term users.

METHODS AND FINDINGS

We conducted a multicenter two-arm, cluster randomized controlled trial in 3 health districts in Spain (primary health centers [PHCs] in Balearic Islands, Catalonia, and Valencian Community) from September 2016 to May 2018. The 81 PHCs were randomly allocated to the intervention group (n = 41; 372 GPs) or the control group (n = 40; 377 GPs). GPs were not blinded to the allocation; however, pharmacists, researchers, and trial statisticians were blinded to the allocation arm. The intervention consisted of a workshop about the appropriate prescribing of BZDs and tapering-off long-term BZD use using a tailored stepped dose reduction with monthly BZD prescription feedback and access to a support web page. The primary outcome, based on 700 GPs (351 in the control group and 349 in the intervention group), compared changes in BZD prescriptions in defined daily doses (DDDs) per 1,000 inhabitants per day after 12 months. The 2 secondary outcomes were the proportion of long-term users (≥6 months) and the proportion of long-term users over age 65 years. Intention-to-treat (ITT) analysis was used to assess all clinical outcomes. Forty-nine GPs (21 intervention group and 28 control group) were lost to follow-up. However, all GPs were included in the ITT analysis. After 12 months, there were a statistically significant decline in total BZD prescription in the intervention group compared to the control group (mean difference: -3.24 DDDs per 1,000 inhabitants per day, 95% confidence interval (CI): -4.96, -1.53, p < 0.001). The intervention group also had a smaller number of long-term users. The adjusted absolute difference overall was -0.36 (95% CI: -0.55, -0.16, p > 0.001), and the adjusted absolute difference in long-term users over age 65 years was -0.87 (95% CI: -1.44, -0.30, p = 0.003). A key limitation of this clustered design clinical trial is the imbalance of some baseline characteristics. The control groups have a higher rate of baseline BZD prescription, and more GPs in the intervention group were women, GPs with a doctorate degree, and trainers of GP residents.

CONCLUSIONS

A multicomponent intervention that targeted GPs and included educational meeting, feedback about BZD prescriptions, and a support web page led to a statistically significant reduction of BZD prescriptions and fewer long-term users. Although the effect size was small, the high prevalence of BZD use in the general population suggests that large-scale implementation of this intervention could have positive effects on the health of many patients.

Deprescribing zolpidem reduces falls and fractures in patients with cirrhosis

Background & Aims

Benzodiazepines are associated with an increased risk of harm in patients with cirrhosis. However, stopping benzodiazepines must be done with care to avoid withdrawal or other unintended consequences. The impact of deprescribing on patients with cirrhosis is unknown.

Methods

We emulated a hypothetical 3-year trial of benzodiazepine deprescription among Medicare enrollees with compensated cirrhosis who lacked other life-limiting diagnoses. All received continuous benzodiazepine prescriptions for the 6-months prior to their diagnosis of cirrhosis. During a 90-day landmark period following their diagnosis of cirrhosis, patients were classified as complete deprescribers (no benzodiazepines dispensed), continuous users, or partial deprescribers. We used inverse probability treatment weighting to compare complete deprescribers to continuous users of traditional benzodiazepines and zolpidem. Outcomes accounted for competing risk of mortality and included incident decompensation (hepatic encephalopathy, ascites, or variceal bleeding), fractures, falls, and alcohol-related hospitalizations.

Results

There were 1,651 and 1,463 continuous users of traditional benzodiazepines and zolpidem, respectively, and 728 complete deprescribers. Patients were aged a median of 68 years, 24% had alcohol-related cirrhosis. There was no difference in the risk of death or decompensation for continuous users and deprescribers. Among deprescribers of traditional benzodiazepines, there was no improvement in the risk of falls or fractures. However, compared to continuous zolpidem users, deprescribers had a lower risk of falls (23.2% vs. 31%, p = 0.04) and fractures (21% vs. 29%, p = 0.02).

Conclusions

Deprescribing zolpidem reduces the risk of falls and fractures. However, deprescribing benzodiazepines does not improve the risk of decompensation. Efforts to safely address the indications for benzodiazepines such as insomnia and anxiety are urgently needed.

Lay summary

Many people with cirrhosis have anxiety, depression, and sleep disorders. Increasingly, patients with cirrhosis are treated with sedating medications called benzodiazepines, including valium, alprazolam (‘Xanax’), clonopin, and the sleep-aid zolpidem (‘Ambien’), which can cause falls, broken bones, and maybe other brain disorders. For this reason, many researchers are interested in trials of ‘deprescribing’ (stopping) benzodiazepines. However, no trials have been performed. We used health record data to simulate a trial of deprescribing. We found that stopping benzodiazepines may reduce the chance of falls or broken bones, but it does not improve survival or liver health.

•

Benzodiazepines are frequently and increasingly prescribed to patients with cirrhosis.

•

Benzodiazepines may increase the risk of falls and fractures and hepatic encephalopathy.

•

Trials of benzodiazepine deprescribing have not been undertaken.

•

In this emulated clinical trial, benzodiazepine deprescribing did not decrease the risk of cirrhosis decompensation.

•

Zolpidem deprescribing was strongly associated with reduced falls and fractures.

Managing the misuse potential and risk of psychological harm from gabapentinoids in primary care in New Zealand

Gabapentinoid prescribing is increasing in New Zealand. International evidence suggests that this prescribing trend is followed by increasing harms, including misuse, dependence, overdose, and psychological harms including suicidal thoughts or behaviours. However, there is limited guidance for prescribers on how to manage these potential harms. Here, we summarise the current international literature and identify three main risk factors that can be used for screening purposes when considering prescribing a gabapentinoid, to identify patients that may be at greater risk of harm. Based on current knowledge of harms, we provide guidance to prescribers on monitoring patients taking gabapentinoids. Finally, we summarise the evidence regarding tapering, and highlight key knowledge gaps including other interventions, referral, and data from primary care populations.

Trends in the Prescription of Benzodiazepine Receptor Agonists from 2009 to 2020: A Retrospective Study Using Electronic Healthcare Record Data of a University Hospital in Japan

In recent years, the prescription trends of benzodiazepine receptor agonists (BZRAs) have not been investigated in Japan despite the publication of guidelines that promote cautious use of BZRAs. The prescription trend of BZRAs was assessed using the electronic healthcare records data of a University Hospital in Japan. The data from April 2009 to March 2021 were used. The following three types of outcomes were set: the proportion of patients who were prescribed with BZRAs within those prescribed hypnotics or anxiolytics; the mean number of the types of prescribed BZRAs, and the mean average daily doses of BZRAs. The same analysis was conducted for benzodiazepines (BZDs) and non-benzodiazepines (Z-drugs). As a result, we found that the proportions of patients prescribed BZRAs within those prescribed hypnotics or anxiolytics began to decrease, particularly from 2015 for patients aged <75 years and those aged ≥75 years. Further, the degree of decrease was larger in patients aged ≥75 years. The proportion for BZDs decreased particularly in the study period, and the proportion for Z-drugs also began to decrease approximately from 2016 in patients aged ≥75 years. The results suggest a possibility that guidelines affected the decreased prescriptions of BZRAs.

'I just thought that it was such an impossible thing': A qualitative study of barriers and facilitators to discontinuing long-term use of benzodiazepine receptor agonists using the Theoretical Domains Framework

Introduction

Existing interventions to reduce long‐term benzodiazepine receptor agonist (BZRA) use lack theoretical underpinning and detailed descriptions. This creates difficulties in understanding how interventions work and how to replicate them in practice. The Theoretical Domains Framework (TDF) can be used to identify behaviour change determinants to target during intervention development.

Objective

To explore barriers and facilitators to discontinuing BZRA use from the perspective of both current and previous long‐term BZRA users.

Design/Setting and Participants

Semistructured TDF‐based interviews were conducted with community‐based individuals with current or previous experience of long‐term BZRA use. Data were recorded, transcribed and analysed using the framework method.

Results

Twenty‐eight individuals were interviewed. Despite commonalities in perceived barriers/facilitators to discontinuing BZRA use within individual TDF domains, individual participants had different experiences of identified determinants of BZRA discontinuation. For example, both similarities and differences existed within and between each participant group in terms of knowledge of the appropriate duration of BZRA use (‘Knowledge’ domain) and experience of withdrawal symptoms (‘Reinforcement’ domain). Compared to previous users, current users typically anticipated more barriers to discontinuing BZRA use and fewer positive consequences of discontinuation.

Conclusion

This study reports on barriers and facilitators to discontinuing BZRA use from the perspectives of current and previous long‐term users. The findings highlight the challenging nature of BZRA discontinuation and a multitude of barriers that impact participants’ behaviour regarding BZRA use. Future work will involve developing a theory‐based intervention to support BZRA discontinuation in primary care.

Patient Contribution

The study included patients as participants.

Cognitive Behavioral Therapy and Acceptance and Commitment Therapy for the Discontinuation of Long-Term Benzodiazepine Use in Insomnia and Anxiety Disorders

Benzodiazepines have proven to be highly effective for treating insomnia and anxiety. Although considered safe when taken for a short period of time, a major risk–benefit dilemma arises in the context of long-term use, relating to addiction, withdrawal symptoms, and potential side effects. For these reasons, benzodiazepines are not recommended for treating chronic sleep disorders, anxiety disorders, nor for people over the age of 65, and withdrawal among long-term users is a public health issue. Indeed, only 5% of patients manage to discontinue using these drugs on their own. Even with the help of a general practitioner, this rate does not exceed 25 to 30% of patients, of which approximately 7% manage to remain drug-free in the long term. Cognitive Behavioral Therapies (CBT) offer a crucial solution to this problem, having been shown to increase abstinence success to 70–80%. This article examines traditional and novel CBT techniques in this regard, such as Acceptance and Commitment Therapy, which address both the underlying condition (insomnia/anxiety) and the substance-related disorder. The theoretical framework and evidence supporting the use of these approaches are reviewed. Finally, current research gaps are discussed, and key research perspectives are proposed.

The effect of cognitive behavioural therapy for insomnia on sedative-hypnotic use: A narrative review

Although cognitive behavioural therapy for insomnia (CBTi) is the recommended 'first-line' treatment for insomnia, most patients are initially treated with sedative-hypnotic medications. Given the risk of impaired cognitive and psychomotor performance, serious adverse events, and long-term dependence associated with sedative-hypnotics, guidelines recommend that prescriptions should be limited to short-term use and that patients are provided with support for withdrawal where possible. CBTi is an effective insomnia treatment in the presence of sedative-hypnotic use. Furthermore, guidelines recommended that CBTi techniques are utilised to facilitate withdrawal from sedative-hypnotics. However, there is very little research evaluating the effect of CBTi on reduced medication use. The current narrative review integrates 95 studies including over 10,000 participants, investigating the effect of CBTi on reduced sedative-hypnotic use in different populations (e.g., hypnotic-dependent patients, older adults, military personnel), settings (e.g., primary care settings, psychiatric inpatients), CBTi modalities (e.g., self-administered reading/audio materials, digital, and therapist-administered), and in combination with gradual dose reduction programs. Based on this research, we discuss the theoretical mechanistic effects of CBTi in facilitating reduced sedative-hypnotic use, provide clear recommendations for future research, and offer pragmatic clinical suggestions to increase access to CBTi to reduce dependence on sedative-hypnotics as the 'default' treatment for insomnia.

Harm reduction in the time of COVID-19: Case study of homelessness and drug use in Dublin, Ireland

Dublin appears to have performed very well as compared to various scenarios for COVID-19 mortality amongst homeless and drug using populations. The experience, if borne out by further research, provides important lessons for policy discussions on the pandemic, as well as broader lessons about pragmatic responses to these key client groups irrespective of COVID-19. The overarching lesson seems that when government policy is well coordinated and underpinned by a science-driven and fundamentally pragmatic approach, morbidity and mortality can be reduced. Within this, the importance of strategic clarity and delivery, housing, lowered thresholds to methadone provision, Benzodiazepine (BZD) provision and Naloxone availability were key determinants of policy success. Further, this paper argues that the rapid collapse in policy barriers to these interventions that COVID-19 produced should be secured and protected while further research is conducted.

Benzodiazepine Use among Medicare, Commercially Insured, and Veteran Older Adults, 2013-2017

BACKGROUND/OBJECTIVES

Benzodiazepines (BZDs) are widely prescribed to older adults. Although prescribing has declined in the U.S. Department of Veterans Affairs (VA), Medicare introduced BZD coverage in 2013. It is unknown whether declines in the VA have been widespread among older adults in the United States.

DESIGN

Observational study in traditional fee-for-service Medicare, commercial insurance, and the VA.

SETTING

United States, 2013-2017.

PARTICIPANTS

Adults aged 55 and older in traditional Medicare (234,290,693 person-months), commercial insurance (337,827,125 person-months), and the VA (256,590,369 person-months).

MEASUREMENTS

(1) Change in BZD and BZD-opioid co-prescribing modeled by Poisson regression over time; and (2) standardized ratios of BZD and BZD-opioid co-prescribing, using Medicare as the reference.

RESULTS

From April 2013 to December 2017, the monthly percentage of adults aged 55 and older who received BZDs fell from 10.4% to 9.3% in Medicare, 6.6% to 6.5% in commercial insurance, and 5.7% to 3.0% in the VA. Monthly BZD-opioid co-prescribing over the same time fell from 4.0% to 3.0% in Medicare, 2.3% to 2.0% in commercial, and 2.2% to .6% for the VA. Age- and sex-adjusted rates of decline for BZD and BZD-opioid co-prescribing were statistically significant for all systems. Annual BZD rate reductions were .98 (Medicare), .99 (commercial), and .87 (VA; P < .001 for all); co-prescribing rate reductions were .95, .99, and .75 (P < .001 for all). Using standardized ratios accounting for demographic and clinical characteristics, both prescribing and co-prescribing were lowest for the VA relative to Medicare (standardized BZD ratio = .40; 95% confidence interval [CI] = .39-.40; standardized BZD-opioid co-prescribing ratio = .35; 95% CI = .35-.35). Prescribing in commercial insurance was also lower (BZD = .65; 95% CI = .65-.65; BZD-opioid co-prescribing = .65; 95% CI = .65-.65).

CONCLUSION

BZD prescribing has declined much more to older adults receiving care through the VA than Medicare or commercial insurance. Other systems may learn from strategies implemented in the VA.

Brief interventions targeting long-term benzodiazepine and Z-drug use in primary care: a systematic review and meta-analysis

AIMS

To assess the effectiveness of brief interventions in primary care aimed at reducing or discontinuing long-term benzodiazepine/Z-drug (BZRA) use.

METHOD

Systematic review of randomized controlled trials of brief interventions in primary care settings aimed at reducing or discontinuing long-term BZRA use in adults taking BZRAs for ≥ 3 months. Four electronic databases were searched: PubMed, EMBASE, PsycINFO and CENTRAL. The primary outcome was BZRA use, classified as discontinuation or reduction by ≥ 25%. The Theoretical Domains Framework (TDF) was used to retrospectively code behavioural determinants targeted by the interventions. The Behaviour Change Technique (BCT) Taxonomy was used to identify the interventions' active components. Study-specific estimates were pooled, where appropriate, to yield summary risk ratios (RRs) and 95% confidence intervals (CIs). Pearson's correlations were used to determine the relationship between intervention effect size and the results of both the TDF and BCT coding.

RESULTS

Eight studies were included (n = 2071 patients). Compared with usual care, intervention patients were more likely to have discontinued BZRA use at 6 months (eight studies, RR = 2.73, 95% CI = 1.84-4.06) and 12 months post-intervention (two studies, RR = 3.41, 95% CI = 2.22-5.25). TDF domains 'knowledge', 'memory, attention and decision processes', 'environmental context and resources' and 'social influences' were identified as having been included in every intervention. Commonly identified BCTs included 'information about health consequences', 'credible source' and 'adding objects to the environment'. There was no detectable relationship between effect size and the results of either the TDF or BCT coding.

CONCLUSION

Brief interventions delivered in primary care are more effective than usual care in reducing and discontinuing long-term benzodiazepine/Z-drug use.

Potentially addictive drugs dispensing to patients receiving opioid agonist therapy: a register-based prospective cohort study in Norway and Sweden from 2015 to 2017

OBJECTIVES

To compare the use of benzodiazepines, z-hypnotics, gabapentinoids, opioids and centrally acting stimulants (CAS) among patients who had received opioid agonist therapy (OAT) in Norway and Sweden during the period 2015 - 2017.

DESIGN

A register-based prospective cohort study using information about dispensed drugs from the Norwegian Prescription Database and Swedish Prescribed Drug Register.

SETTING

Patients who were dispensed OAT opioids from pharmacies.

PARTICIPANTS

A total of 7176 Norwegian and 3591 Swedish patients on OAT were included.

OUTCOME MEASURES

The number and frequency of potentially addictive drugs dispensed were calculated for the two countries. The mean daily doses of dispensed benzodiazepines and z-hypnotics were summarised by calculating benzodiazepines in diazepam equivalents and z-hypnotics in zopiclone equivalents.

RESULTS

In 2017, 46% of patients in Norway, and 15% in Sweden, were dispensed a benzodiazepine. Moreover, 14% in Norway and 26% in Sweden received z-hypnotics. Gabapentinoids were dispensed to 10% of patients in Norway and 19% of patients in Sweden. In Norway, 6% and 12% of the patients received strong and weak non-OAT opioids, respectively, whereas in Sweden 10% were dispensed strong non-OAT opioids and 5% weak non-OAT opioids . CAS were dispensed to 4% in Norway and 18% in Sweden. The mean daily doses of benzodiazepines were 16 and 17 mg diazepam equivalents in Norway and Sweden, respectively. For z-hypnotics, the mean daily dose was 8 mg zopiclone equivalents in both countries. 'Benzodiazepines and z-hypnotics' was the most dispensed drug combination in 2017. Similar results were found in 2015 and 2016.

CONCLUSIONS

Nearly half of those patients who were dispensed an OAT opioid in Norway and Sweden were dispensed potentially addictive drugs. The differences identified between Norway and Sweden might be related to differences in eligibility guidelines and restrictions with respect to OAT.

Discontinuation or reduction in benzodiazepine use by treatment with the traditional herbal medicine Hangekobokuto, case reports

In this report, we present two cases in which benzodiazepines (BZDs) were able to be successfully reduced or discontinued by treatment with traditional Japanese herbal medicine (Kampo medicine), including Hangekobokuto (HKT). These two patients with long-term use of BZDs due to mental disorders suffered epigastric symptoms. After starting Kampo therapy including HKT, their epigastric symptoms were improved and they were able to reduce or discontinue the use of BZDs. This suggests that HKT is a potentially promising substitutive pharmacotherapy for patients with long-term use of BZDs. HKT should be considered as a treatment for patients with mental disorders who have taken BZDs for a long time and suffer from medically unexplained epigastric symptoms.

Role of nurses in supporting proactive deprescribing

Deprescribing is the term used to describe the discontinuation of medicines. It can be either 'reactive', for example in response to an adverse event or therapeutic failure, or 'proactive', when the prescriber and patient decide to discontinue the medicine because its future benefits no longer outweigh its potential for harm. At present, there is a limited amount of proactive deprescribing activity in primary and secondary care. This article provides the rationale for increasing proactive deprescribing activity, lists the medicines this relates to, identifies the barriers and enablers to its implementation, and describes the potential role of the nurse in this process.

Cost-effectiveness of brief structured interventions to discontinue long-term benzodiazepine use: an economic analysis alongside a randomised controlled trial

Background: In Spain, long-term use of benzodiazepine is prevalent in 7% of the population; however, this longer-term use lacks clinical benefits, costs €90million per year and side-effects further add extra cost through adverse health outcomes. This study aims to estimate the cost-effectiveness of primary care services stepped dose reduction of long-term benzodiazepines using either Structured Interview with Follow-up (SIF) or Without Follow-up (SIW), compared to Treatment as Usual (TAU). Design: Cost-effectiveness analysis was conducted alongside randomised control utilizing data from three arm cluster randomized trial. Setting: Primary care. Participants: 75 general practitioners were randomised to one of the three arms (TAU, SIW, SIF). Measurements: Cost and Cost per Quality-Adjusted Life Year (QALY) Results: Compared to usual care, providing SIW per participant costs an additional €117.94 and adding patient follow-up, €218.4. As a result of intervention, participants showed a gain of, on average, for SIW 0.0144 QALY (95% CI -0.0137 to 0.0425) and for SIF 0.0340 QALYs (0.0069 to 0.0612). The Incremental Cost Effectiveness Ratio was €8190.28/QALY (SIW) and €6423.53/QALY (SIF). At the Spanish reimbursement threshold (€45,000 per QALY) the chance interventions are cost effective is 79.8% for SIW and 97.7% for SIF. Conclusions: Brief structured interventions to discontinue long-term benzodiazepine use represent value for money, particularly with scheduled follow-up appointments, and would represent a cost-effective investment by the Spanish healthcare to reduce prevalence of long-term use.

Elaboração e validação do protocolo de desprescrição do clonazepam em idosos

Introdução: Algumas alterações fisiológicas que ocorrem no indivíduo idoso favorecem o acúmulo e a intoxicação por medicamentos. Dentre estes, podemos citar a classe dos benzodiazepínicos, medicamentos que, apesar de amplamente prescritos, principalmente para tratamento de distúrbios do sono e ansiedade, são considerados potencialmente inapropriados para o uso em idosos. Portanto, a elaboração de protocolos para desprescrição desses medicamentos é estratégia necessária na gestão do cuidado dos pacientes geriátricos. Objetivo: Elaborar e validar um protocolo de desprescrição do clonazepam para idosos que fazem uso deste medicamento para ansiedade ou insônia. Métodos: Estudo metodológico, desenvolvido em duas etapas, sendo elas a elaboração e a validação do protocolo de desprescrição do clonazepam para idosos que fazem uso desse medicamento para ansiedade ou insônia, excetuando-se aqueles que preenchem os critérios de exclusão. A elaboração do protocolo resultou em três produtos: um fluxograma de desprescrição, um folheto sobre higiene do sono e um folheto contendo os benefícios da desprescrição do clonazepam sob supervisão médica. A validação do protocolo foi realizada por médicos especialistas, por meio da Técnica de Delphi. Já na validação dos folhetos, participaram, além dos especialistas, indivíduos com 60 anos ou mais, de ambos os sexos, que não fizessem uso do clonazepam. A partir dos resultados obtidos, foi analisada a concordância da avaliação por meio do Coeficiente de Validade de Conteúdo (CVC), uma vez que essa ferramenta objetiva medir o grau de concordância dos juízes participantes do processo de validação. Resultados: O fluxograma foi considerado validado após a segunda rodada de avaliação, pois todos os itens avaliados obtiveram CVC igual ou superior a 0,8 nesta rodada. Os folhetos foram considerados validados já na primeira rodada de avaliação, pois todos os itens também obtiveram CVC superior a 0,8 durante esta rodada. Conclusão: Considerando os resultados obtidos, o protocolo se apresenta como uma ferramenta importante ao guiar a conduta médica no processo de desprescrição do clonazepam.

Benzodiazepine Prescribing in People with Chronic Obstructive Pulmonary Disease: Clinical Considerations

Benzodiazepines, available clinically for almost six decades, are still one of the most widely prescribed classes of medication. The proportion of the population prescribed benzodiazepines increases with age, and harms also increase with age. The prevalence of prescribing in people > 85 years of age is as high as one in three, including in people with chronic obstructive pulmonary disease (COPD). The prevalence of COPD also increases with age. In COPD, indications cited for prescribing a benzodiazepine include anxiety, sleep disorders, or chronic breathlessness. Each of these symptoms is prevalent in the population with COPD, especially later in the course of the illness. For anxiety and insomnia, there is evidence to support short-term use, with little robust evidence to support prescribing for the symptomatic reduction of chronic breathlessness. People prescribed benzodiazepines are more likely to experience drowsiness or somnolence, exacerbations of their COPD, and respiratory tract infections. Furthermore, the longer people take benzodiazepines, the more likely they will become dependent on them. Prescribing patterns vary internationally but prescriptions of longer-acting benzodiazepines are declining in favour of shorter-acting compounds. Other evidence-based therapies that can more safely treat these problematic symptoms are available. For people already taking benzodiazepines, there are a number of interventions that have been shown to reduce the rate of prescribing. For people with COPD and not taking a benzodiazepine, but with symptoms where there is evidence of benefit, clinicians should weigh carefully the potential net benefit and prescribe at the lowest dose for the briefest time possible.

A Qualitative Study of Use of Mindfulness to Reduce Long-Term Use of Habit-Forming Prescription Drugs

Objective: The aim of this study was to study how participants used a mindfulness-based program-Mindfulness Based Relapse Prevention to reduce use of habit-forming prescription drugs after long-term use. We explored participants' descriptions of their post-intervention strategies for controlling medication intake. Method: Eighteen participants provided semi-structured qualitative interviews shortly after completion of the program and 13 participants were also interviewed 1 year after completion. Participants were asked about the conditions that originally led to use of medication, how they had attempted prior to the course to cope with problems associated with these conditions and their prescription drug-use, and whether and how their coping strategies had changed after participation in the program. Thematic analysis was performed within the framework of a realist epistemology, with an emphasis on researcher reflexivity. Results: The following themes were identified in the material: Increased present-moment sensory awareness, Observing without controlling, Self-acceptance, Making conscious choices, Non-judgmental self-guidance, Sense of control, and Challenges of learning and using mindfulness. Although these findings are closely related to the specific needs of our sample-mainly coping with tapering use of prescription drugs-they are largely in line with existing research on mindfulness interventions. An exception is the theme "Non-judgmental self-guidance," which encompasses change in individuals' inner dialogue and practical self-care. Conclusions: Analyses suggested that mindfulness might increase individuals' control over medication intake by shifting individuals' attention toward present-moment sensory awareness of concrete stimuli, thereby facilitating other kinds of control, such as non-judgmental inner self-guidance and more adaptive ways of reducing distress. We suggest that it is the moment-to-moment sensory awareness and non-controlling observation of distress, together with inner self-guidance, that differentiates mindful control from dysfunctional attempts at direct, top down control of medication-use.

Beyond Prescriptions Monitoring Programs: The Importance of Having the Conversation about Benzodiazepine Use

: Internationally there is an escalation of prescription-related overdose deaths, particularly related to benzodiazepine use. As a result, many countries have implemented prescription monitoring programs (PMPs) to increase the regulation of benzodiazepine medications. PMPs centralize prescription data for prescribers and pharmacists and generate alerts to high-doses, risky combinations, or multiple prescribers with the aim to reduce inappropriate prescribing and subsequently the potential of patient harm. However, it has become clear that prescribers have been provided with minimal guidance and insufficient training to effectively integrate PMP information into their decision making around prescribing these medications. Accordingly, this paper discusses how PMPs have given rise to a range of unintended consequences in those who have been prescribed benzodiazepines (BDZs). Given that a gradual taper is generally required to mitigate withdrawal from BDZs, there are concerns that alerts from PMPs have resulted in BDZs being ceased abruptly, resulting in a range of unintended harms to patients. It is argued that best practice guidelines based upon a patient-centered framework of decision-making, need to be developed and implemented, in order to curtail the unintended consequences of PMPs. This paper outlines some key considerations when starting the conversation with patients about their BDZ use.

A Durable Minimal Intervention Strategy to Reduce Benzodiazepine Use in a Primary Care Population

Background

Benzodiazepines are commonly prescribed drugs with approximately 10% of adults having used them in the past year. These drugs are clearly addictive, yet many patients are prescribed these for years, with long-term side effects. The present study aimed to investigate whether patients on repeat diazepam prescription had their prescription reviewed to reduce and to stop the repeat prescription wherever appropriate, and whether these changes were sustained at 24 months.

Methods

The present study used a minimal intervention strategy to reduce diazepam use in a semi-rural general practice. Patients with a current prescription for diazepam were invited to visit their general practitioner for a review. Dose reduction grids were formulated for each individual to facilitate a downward titration by 1 mg each wk/mo. Patients with psychiatric co-morbidity were also included. Interrupted time series methods were applied to the monthly data. The outcomes were evaluated at 12 and 24 months.

Results

Ninety-two patients had diazepam on repeat prescription with 87 (94.6%) attending the review appointment. Twenty-seven patients (29.3%) were under psychiatric review and were supported by the psychiatrist with a downward titration regime. At 24 months, 63 patients (81.8% of the 77 still at the practice) had stopped or were in the process of stopping regular use of diazepam. A statistically significant reduction in total monthly diazepam prescription was observed (from 2.2 to 0.7 defined daily dose/1,000 patients/d).

Conclusion

This minimal intervention strategy, in collaboration between primary and secondary care, produced a durable reduction in overall diazepam prescription at the general practice.

British Association for Psychopharmacology consensus statement on evidence-based treatment of insomnia, parasomnias and circadian rhythm disorders: An update

This British Association for Psychopharmacology guideline replaces the original version published in 2010, and contains updated information and recommendations. A consensus meeting was held in London in October 2017 attended by recognised experts and advocates in the field. They were asked to provide a review of the literature and identification of the standard of evidence in their area, with an emphasis on meta-analyses, systematic reviews and randomised controlled trials where available, plus updates on current clinical practice. Each presentation was followed by discussion, aiming to reach consensus where the evidence and/or clinical experience was considered adequate, or otherwise to flag the area as a direction for future research. A draft of the proceedings was circulated to all speakers for comments, which were incorporated into the final statement.

Benzodiazepine usage and patient preference for alternative therapies: A descriptive study

BACKGROUND AND AIMS

The prevalence of chronic benzodiazepine use in primary care settings remains high despite clear evidence of adverse health outcomes resulting from long-term use and the availability of effective alternative behavioural therapies. Eliciting factors influencing past or current usage experience of benzodiazepine users and their future behavioural intention regarding discontinuation or alternative behavioural therapy adoption could be useful in developing informed strategies facilitating successful benzodiazepine withdrawal in long-term users. The aim of this study was to identify patient factors influencing their current long-term benzodiazepine use, past withdrawal attempt, and future intention to trial safer alternative behavioural therapies. Additionally, the study also aimed to explore patients' preference for information sources on behavioural therapies.

METHODS

Point of purchase surveys were conducted with patients obtaining benzodiazepines from selected pharmacies across New South Wales (NSW), Australia. Survey items included the Beliefs about Medicines Questionnaire (BMQ-specific), questions about patient's sociodemographic characteristics, as well as their views about long-term benzodiazepine use and behavioural therapies.

RESULTS

Seventy-five patients were recruited from 12 pharmacies across New South Wales (NSW). The surveys were conducted from November 2016 to July 2017. The mean (±SD) age of the participants was 54.3 (±16.7) with a range of 23 to 86 years, and 67% of the participants had been using the benzodiazepine for at least 1 year. Lower-education levels, stronger beliefs about the necessity of use, and lower concerns about ongoing benzodiazepine use were significantly associated with prolonged use. Sixty-four percent of the participants were not interested in behavioural therapies, and there was a significant relationship between the participants' future preference for behavioural therapies and their concerns about the potential adverse effects of benzodiazepines. A majority of the participants rated general practitioners (GPs) as their first choice and pharmacists as the second choice for discussing behavioural therapies.

CONCLUSIONS

Specific individual sociodemographic characteristics of benzodiazepine users and their medication-related beliefs influence their current benzodiazepine usage and future intention to trial behavioural therapies as an alternative to their benzodiazepines. Based on the reported preferences of benzodiazepine users in this study, developing and evaluating GP-pharmacist collaborative services to improve the uptake of behavioural therapies as an alternative to benzodiazepines can be recommended.

Electroacupuncture for tapering off long-term benzodiazepine use: A randomized controlled trial

OBJECTIVE

To evaluate the efficacy of using electroacupuncture as an adjunct treatment in enhancing the benzodiazepine cessation rate in long-term benzodiazepine users.

METHODS

This was a randomized, assessor- and subject-blinded, controlled trial. One hundred and forty-four long-term benzodiazepine users were randomly assigned to receive either electroacupuncture or placebo acupuncture (a sham itervention using non-invasive placebo needles) combined with a gradual benzodiazepine tapering schedule for 4 weeks. The primary outcome was the cessation rate of benzodiazepine use. Subjects were assessed on their benzodiazepine usage, benzodiazepine withdrawal symptoms, insomnia severity, and anxiety and depressive symptoms at baseline, week 6 and week 16.

RESULTS

The cessation rates of the electroacupuncture and placebo acupuncture groups at 12 weeks post-treatment were 9.17% and 10.83%, respectively. Both groups showed a reduction in benzodiazepine usage by a self-completed drug record at week 16 (compared to baseline: electroacupuncture group -40.23% versus placebo acupuncture group -48.76%). However, no significant between-group differences were found in the benzodiazepine cessation rate, reduction in benzodiazepine usage, and other secondary measures across all the study time points.

CONCLUSIONS

Electroacupuncture showed a similar cessation rate in benzodiazepine use to that of non-invasive placebo acupuncture in long-term users during a 4-week gradual tapering schedule. The evidence did not support advantages of electroacupuncture over non-invasive placebo acupuncture on reducing insomnia, anxiety, depression, or other withdrawal symptoms during the gradual tapering schedule. Despite a 40% decrease in the benzodiazepine usage in both groups, the effects may be attributed to the non-specific effects of acupuncture.

Intervention to reduce benzodiazepine prescriptions in primary care, study protocol of a hybrid type 1 cluster randomised controlled trial: the BENZORED study

INTRODUCTION

Benzodiazepines (BZDs) are mainly used to treat anxiety and sleep disorders, and are often prescribed for long durations, even though prescription guidelines recommend short-term use due to the risk of dependence, cognitive impairment, and falls and fractures. Education of general practitioners (GPs) regarding the prescription of BZDs may reduce the overuse and of these drugs.The aims of this study are to analyse the effectiveness of an intervention targeted to GPs to reduce BZD prescription and evaluate the implementation process.

METHODS AND ANALYSIS

The healthcare centres in three regions of Spain (Balearic Islands, Catalonia and Community of Valencia) will be randomly allocated to receive a multifactorial intervention or usual care (control). GPs in the intervention group will receive a 2-hour workshop about best-practice regarding BZD prescription and BZD deprescribing, monthly feedback about their BZD prescribing practices and access to a support web page. Outcome measures for each GP are the defined daily dosage per 1000 inhabitants per day and the proportion of long-term BZD users at 12 months. Data will be collected from the electronic prescription database of the public health system, and will be subjected to intention-to-treat analysis. Implementation will be evaluated by mixed methods following the five domains of the Consolidated Framework For Implementation Research.

ETHICS AND DISSEMINATION

This study was approved by the Balearic Islands Ethical Committee of Clinical Research (IB3065/15), l'IDIAP Jordi Gol Ethical Committee of Clinical Research (PI 15/0148) and Valencia Primary Care Ethical Committee of Clinical Research (P16/024). The results will be submitted for publication in peer-reviewed journals.

Hypnotic Discontinuation Using a Blinded (Masked) Tapering Approach: A Case Series

Chronic use of hypnotic medications such as benzodiazepines is associated with adverse consequences including increased risk of falls. Efforts to help patients discontinue these medications have had varying levels of success. We developed a blinded (masked) tapering protocol to help patients taper off hypnotics. In this blinded protocol, patients consented to a drug taper but agreed to forego knowledge about the specific tapering schedule or the actual dose each night until the end of the taper. Blinded tapering aims to reduce negative expectancies for withdrawal effects that may impair a patient's successful discontinuation of hypnotics. In preparation for a randomized trial, we tested the feasibility of adding a blinded tapering component to current best evidence practice [supervised hypnotic taper combined with cognitive behavioral therapy for insomnia (CBTI)] in 5 adult patients recruited from an outpatient mental health practice in Oregon. A compounding pharmacy prepared the blinded capsules for each patient. During the gradual blinded taper, each participant completed CBTI. Measures collected included feasibility/process (e.g., recruitment barriers), hypnotic use, the Dysfunctional Beliefs and Attitudes about Sleep Scale, Insomnia Severity Index, Epworth Sleepiness Scale, and Patient Health Questionnaire-9 (depressive symptoms). The intervention was feasible, and participants reported high satisfaction with the protocol and willingness to follow the same treatment again. All five participants successfully discontinued their hypnotic medication use post-treatment. Dysfunctional beliefs/attitudes about sleep and insomnia severity improved. Blinded tapering is a promising new method for improving hypnotic discontinuation among patients treated with a combination of hypnotic tapering plus CBTI.

Deprescribing Benzodiazepines in Older Patients: Impact of Interventions Targeting Physicians, Pharmacists, and Patients

Benzodiazepines (BZDs; including the related Z-drugs) are frequently targets for deprescribing; long-term use in older people is harmful and often not beneficial. BZDs can result in significant harms, including falls, fractures, cognitive impairment, car crashes and a significant financial and legal burden to society. Deprescribing BZDs is problematic due to a complex interaction of drug, patient, physician and systematic barriers, including concern about a potentially distressing but rarely fatal withdrawal syndrome. Multiple studies have trialled interventions to deprescribe BZDs in older people and are discussed in this narrative review. Reported success rates of deprescribing BZD interventions range between 27 and 80%, and this variability can be attributed to heterogeneity of methodological approaches and limited generalisability to cognitively impaired patients. Interventions targeting the patient and/or carer include raising awareness (direct-to-consumer education, minimal interventions, and 'one-off' geriatrician counselling) and resourcing the patient (gradual dose reduction [GDR] with or without cognitive behavioural therapy, teaching relaxation techniques, and sleep hygiene). These are effective if the patient is motivated to cease and is not significantly cognitively impaired. Interventions targeted to physicians include prescribing interventions by audit, algorithm or medication review, and providing supervised GDR in combination with medication substitution. Pharmacists have less frequently been the targets for studies, but have key roles in several multifaceted interventions. Interventions are evaluated according to the Behaviour Change Wheel. Research supports trialling a stepwise approach in the cognitively intact older person, but having a low threshold to use less-consultative methods in patients with dementia. Several resources are available to support deprescribing of BZDs in clinical practice, including online protocols.

Patterns of benzodiazepines use in primary care adults with anxiety disorders

BACKGROUND

Benzodiazepines are among the most commonly prescribed drugs for anxiety disorders. While they are indicated as adjunctive treatment for short-term use according to clinical practice guidelines, previous studies have shown patterns of long-term use of benzodiazepines, which is problematic due to side effects, dependence and potential of abuse. The aims of this study were to examine among a large sample of primary care adults suffering from anxiety disorders: 1) benzodiazepine use patterns; and 2) correlates of long-term benzodiazepine use.

METHODS

Data were drawn from the "Dialogue" project, a large primary care study conducted in 64 primary care clinics in the province of Quebec, Canada. Following a mental health screening in waiting rooms, patients at risk of anxiety or depression completed the Composite International Diagnostic Interview-Simplified (CIDIS). A sample of 740 adults meeting DSM-IV criteria for Generalized Anxiety Disorder, Panic Disorder or Social Anxiety Disorder in the past 12 months took part in this study.

RESULTS

Benzodiazepines were used by 22.6% of participants with anxiety disorders in our primary care sample. A large majority of benzodiazepine users (88.4%) met our indicator of long-term use, as defined by utilization for more than 12 weeks including regular and as-needed use. Based on a logistic regression model, individual correlates associated with long-term benzodiazepine use included: being 30 years or older, having a comorbid physical illness, meeting criteria for comorbid agoraphobia, reporting the use of sleep-aids, and concurrent SSRI utilization.

LIMITATION

Data collection with self-reported questionnaires may be subject to information bias.

CONCLUSIONS

Despite knowledge of the risks of long-term use of benzodiazepines, this remains a pervasive problem. Clinicians need to be mindful of patterns and risk factors leading to long-term use of benzodiazepines in patients with anxiety disorders. Results of this study should raise awareness regarding appropriate prescription practices for benzodiazepines, including decision-making in initiation, duration of prescription, and use of strategies for discontinuation in current long-term benzodiazepine users.

Challenges of the pharmacological management of benzodiazepine withdrawal, dependence, and discontinuation

BACKGROUND

Benzodiazepines (BZDs) are among the most prescribed sedative hypnotics and among the most misused and abused medications by patients, in parallel with opioids. It is estimated that more than 100 million Benzodiazepine (BZD) prescriptions were written in the United States in 2009. While medically useful, BZDs are potentially dangerous. The co-occurring abuse of opioids and BZD, as well as increases in BZD abuse, tolerance, dependence, and short- and long-term side effects, have prompted a worldwide discussion about the challenging aspects of medically managing the discontinuation of BZDs. Abrupt cessation can cause death. This paper addresses the challenges of medications suggested for the management of BZD discontinuation, their efficacy, the risks of abuse and associated medical complications. The focus of this review is on the challenges of several medications suggested for the management of BZD discontinuation, their efficacy, the risks of abuse, and associated medical complications.

METHODS

An electronic search was performed of Medline, Worldwide Science, Directory of Open Access Journals, Embase, Cochrane Library, Google Scholar, PubMed Central, and PubMed from 1990 to 2017. The review includes double-blind, placebo-controlled studies for the most part, open-label pilot studies, and animal studies, in addition to observational research. We expand the search to review articles, naturalistic studies, and to a lesser extent, letters to the editor/case reports. We exclude abstract and poster presentations, books, and book chapters.

RESULTS

The efficacy of these medications is not robust. While some of these medicines are relatively safe to use, some of them have a narrow therapeutic index, with severe, life-threatening side effects. Randomized studies have been limited. There is a paucity of comparative research. The review has several limitations. The quality of the documents varies according to whether they are randomized studies, nonrandomized studies, naturalistic studies, pilot studies, letters to the editors, or case reports.

CONCLUSIONS

The use of medications for the discontinuation of BZDs seems appropriate. It is a challenge that requires further investigation through randomized clinical trials to maximize efficacy and to minimize additional risks and side effects.

Benzodiazepines Withdrawal: Initial Outcomes and Long-Term Impact on Falls in a French Nursing Home

Long-term use of benzodiazepines (BZDs) is known to induce tolerance and dependence, and increase the risk of falls-related injuries in older adults. We present a study carried out in a French nursing home that concerns the implementation of a BZD withdrawal program reassessed at one year. BZD deprescription was achieved by gradual cessation of doses. A secondary benefit of this program was assessed by comparing the number of falls among residents before and after withdrawal. The number of falls was recorded over a six-month period prior to the onset of withdrawal (T1) and then over a six-month period after reassessment at one year (T2). At the beginning, 31 (28.7%) of the patients were under BZD. Total deprescription was obtained for 11 patients. The number of falls per patient over the T1 period was not different between the two groups (future non-withdrawn and withdrawn patients in BZD): 2.1 ± 1.3 and 2.3 ± 0.6 falls per resident, respectively. Conversely, the number of falls per patient was significantly decreased in the population completely withdrawn in BZD between the T1 and T2 periods (2.3 ± 0.6 vs. 0.5 ± 0.2 falls, p = 0.01). The results show that BZD deprescription, through a gradual reduction of doses, is possible to achieve.
