Front Public Health 2022; 10:1014734. [PMID: 36211642 PMCID: PMC9546292 DOI: 10.3389/fpubh.2022.1014734] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 09/05/2022] [Indexed: 01/27/2023] Open
Abstract
Background Contrary to most European guidelines, benzodiazepine receptor agonists (BZRA) are often used continuously at a low dosage, being the most common form of long-term use. In Belgium, BZRA use is monitored by analyzing self-report data about medication use in the last 24 h. This method provides insufficient insight into the terms of use of these psychoactive drugs. Aim To describe trends in BZRA prescribing in Flanders, Belgium, between 2000 and 2019. Design and setting Population-based trend analysis and a case-control study for the year 2019 were done with data from a morbidity registry in general practice. Methods Repeated cross-sectional and joinpoint regression analyses revealed trends in sex- and age-standardized prescription rates among adult patients (18+). Results Overall, BZRA prescriptions increased. The highest overall increase was found among male patients 18-44 years old, with an average annual percentage change of 2.5 (95% CI: 0.9, 4.3). Among 65+ female patients, a decrease was found since 2006, with an annual percentage change of -0.7 (95% CI: -1.3, -0.1). In 2019, 12% of registered patients received minimally one prescription, long-term use was observed in 5%, back pain was the most common morbidity significantly associated with a rise in BZRA prescriptions, and zolpidem was the most prescribed BZRA (22%). Conclusion Despite some statistically significant decreasing trends, an overall increase in BZRA prescriptions was observed throughout the 19-year study period, especially among long-term users of 18-44 years and 65-plus. Zolpidem became the most prescribed BZRA and warrants more attention.

Abstract
Insomnia disorder is common in adults and children. The estimated prevalence ranges from 9% to 15% in the general population, with higher prevalence in certain subpopulations. Hypnotic medications are those that tend to produce sleep and are frequently used to treat insomnia. Commonly used hypnotics in adults include benzodiazepines (BZDs), BZD receptor agonists, antihistamines, antidepressants, melatonin receptor agonists, orexin receptor antagonists, and antipsychotics. However, hypnotic discontinuation is difficult and often unsuccessful. This article discusses strategies to discontinue hypnotics and evidence supporting their use.

Abstract
Patients with chronic insomnia are commonly prescribed hypnotic medications. The long-term effects of chronic hypnotics are not known and discontinuation is encouraged but often difficult to achieve. A gradual taper is preferred to abrupt cessation to avoid rebound insomnia and withdrawal symptoms. Written information provided to the patient about medication discontinuation may be helpful. Cognitive behavioral therapy or behavioral therapies alone can improve hypnotic discontinuation outcomes. There is limited evidence for adjunct medications to assist in hypnotic cessation for insomnia.

A systematic review. Drug Alcohol Depend 2020; 212:107994. [PMID: 32409111 DOI: 10.1016/j.drugalcdep.2020.107994] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 02/29/2020] [Accepted: 03/26/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND Hypnotics (HYP) and benzodiazepines (BZD) are medicines prescribed for the insomnia treatment. Many patients present difficulties in discontinuing the treatment once established. Melatonin (MLT) has been prescribed as a treatment for BZD/HYP detoxification. AIMS The primary objective of this systematic review is to assess the efficacy of MLT and MLT agonists (melatoninergics) in improving the rate of BZD and/or HYP discontinuation among adults with primary insomnia attempting to discontinue BZD and/or HYP. The secondary objective is to evaluate the partial efficacy of melatoninergic drugs in the discontinuation of BZD and/or HYP consumption in subjects that could not stop their consumption. METHOD A search on Web of Science and Scopus was carried out from database inception to July 1st, 2019. RESULTS Three hundred and forty-nine articles were identified but only four were included in the final review. Two were cohort prospective, one placebo-control double blind and one double blind placebo-control cross-over designed study. Total withdrawal (TW) ranged from 0% to 25% in the placebo arm and from 64.3% to 77.8% in the MLT arm. In cohort studies TW figures ranged from 30.8% to 65%. Partial withdrawal ranged between 20% and 30.8% of patients that did not achieve TW with reduction figures of diazepam equivalent dose ranging from 25% to 75%. CONCLUSION MLT has a place in the physician armamentarium to treat the suspension/reduction of BZD/HYP consumption in patients with primary insomnia.

Abstract
Osteoporosis (OP) is a major public health concern, but still OP care does not meet guidelines. Interventions have been developed to improve appropriate OP management. The objective of the present study was to systematically review the current literature to ascertain the efficacy of interventions to improve OP care and characterize interventions taking into account elements related to their potential cost and feasibility. Studies published from 2003 to 2018 were retrieved from PubMed/MEDLINE, Science Direct, Web of Science, Cochrane, and Wiley Online Library databases. Screening of references and quality assessment were independently performed by two reviewers. We classified interventions into three types according to the target of the intervention: health system (structural interventions), healthcare professional (HCP), and patient. Meta-analysis was performed by type of intervention and their effect on two outcomes: prescription of BMD measurement and prescription of OP therapy. A total of 4268 records were screened; 32 studies were included in the qualitative analysis and 29 studies in the quantitative analysis. Structural interventions strongly and significantly improved prescription of BMD measurement (OR = 9.99, 95% CI 2.05; 48.59) and treatment prescription (OR = 3.82, 95% CI 2.16; 6.75). The impact of HCP-centered interventions on BMD measurement prescription did not reach statistical significance (OR = 2.19, 95% CI 0.84; 5.73) but significantly improved treatment prescription (OR = 3.82, 95% CI 2.16; 6.75). Interventions involving patients significantly improved the prescription of BMD measurement (OR = 2.16, 95% CI 1.62; 2.89) and treatment prescription (OR = 1.70, 95% CI 1.35; 2.14). Interventions to improve OP management had a significant positive impact on prescription of BMD measurement but a more limited impact on treatment prescription.

Evaluating Alternative Designs of a Multilevel HIV Intervention in Maharashtra, India: The Impact of Stakeholder Constraints. MDM Policy Pract 2018; 3:2381468318803940.

Abstract
Background. Multilevel interventions combine individual component interventions, and their design can be informed by decision analysis. Our objective was to identify the optimal combination of interventions for alcohol-using HIV+ individuals on antiretroviral drug therapy in Maharashtra, India, explicitly considering stakeholder constraints. Methods. Using an HIV simulation, we evaluated the expected net monetary benefit (ENMB), the probability of lying on the efficiency frontier (PEF), and annual program costs of 5,836 unique combinations of 15 single-focused HIV risk-reduction interventions. We evaluated scenarios of 1) no constraints (i.e., maximize expected value), 2) short-term budget constraints (limits on annual programmatic costs of US$200,000 and $400,000), and 3) a constraint stemming from risk aversion (requiring that the strategy has >50% PEF). Results. With no constraints, the combination including long individual alcohol counseling, text-message adherence support, long group counseling for sex-risk, and long individual counseling for sex-risk (annual cost = $428,886; PEF ∼27%) maximized ENMB and would be the optimal design. With a cost constraint of $400,000, the combination including long individual alcohol counseling, text-message adherence support, brief group counseling for sex-risk, and long individual counseling for sex-risk (annual cost = $374,745; PEF ∼4%) maximized ENMB. With a cost constraint of $200,000, the combination including long individual alcohol counseling, text-message adherence support, and brief group counseling for sex-risk (annual cost = $187,335; PEF ∼54%) maximized ENMB. With the risk aversion constraint, the same configuration (long individual alcohol counseling, text-message support, and brief group counseling for sex-risk) maximized health benefit. Conclusion. Evaluating the costs, risks, and projected benefits of alternatives supports informed decision making prior to initiating study; however, stakeholder constraints should be explicitly included and discussed when using decision analyses to guide study design.

Patient-centered care interventions to reduce the inappropriate prescription and use of benzodiazepines and z-drugs: a systematic review. PeerJ 2018; 6:e5535. [PMID: 30345166 PMCID: PMC6190800 DOI: 10.7717/peerj.5535] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 08/08/2018] [Indexed: 12/30/2022] Open
Abstract
Background Benzodiazepines (BZDs) and z-drugs are effective drugs, but they are prescribed excessively worldwide. International guidelines recommend a maximum treatment duration of 4 weeks. Although these drugs are effective in the short-term, long-term BZD therapy is associated with considerable adverse effects, the development of tolerance and, finally, addiction. However, there are different interventions in terms of patient-centered care that aim to reduce the use of BZDs and z-drugs as well as assist health care professionals (HCPs) in preventing the inappropriate prescription of BZDs. Aim The aim of this systematic review was to identify interventions that promote patient-centered treatments for inappropriate BZD and z-drug use and to analyze their effectiveness in reducing the inappropriate use of these drugs. Methods To identify relevant studies, the PubMed, EMBASE, PsycINFO, Psyndex, and Cochrane Library databases were searched. Studies with controlled designs focusing on adult patients were included. Trials with chronically or mentally ill patients were excluded if long-term BZD and z-drug use was indicated. Study extraction was performed based on the Cochrane Form for study extraction. To assess the quality of the studies, we used a tool based on the Cochrane Collaboration’s tool for assessing the risk of bias in randomized trials. Results We identified 7,068 studies and selected 20 for systematic review. Nine interventions focused on patients, nine on HCPs, and two on both patients and HCPs. Intervention types ranged from simple to multifaceted. Patient-centered interventions that provided patient information effectively increased the appropriate use of BZDs. The educational approaches for HCPs that aimed to achieve appropriate prescription reported inconsistent results. The methods that combined informing patients and HCPs led to a significant reduction in BZD use. Conclusions This is the first review of studies focused on patient-centered approaches to reducing the inappropriate prescription and use of BZDs and z-drugs. The patient-centered dimension of patient information was responsible for a decrease in BZD and z-drug consumption. Further, in some studies, the patient-centered dimensions responsible for reducing the prescription and use of BZDs and z-drugs were the clinician’s essential characteristics and clinician-patient communication.

Abstract
BACKGROUND Long-term sedative use is prevalent and associated with significant morbidity, including adverse events such as falls, cognitive impairment, and sedation. The development of dependence can pose significant challenges when discontinuation is attempted as withdrawal symptoms often develop. We conducted a scoping review to map and characterize the literature and determine opportunities for future research regarding deprescribing strategies for long-term benzodiazepine and Z-drug (zopiclone, zolpidem, and zaleplon) use in community-dwelling adults. METHODS We searched PubMed, Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, CINAHL, TRIP, and JBI Ovid databases and conducted a grey literature search. Articles discussing methods for deprescribing benzodiazepines or Z-drugs in community-dwelling adults were selected. RESULTS Following removal of duplicates, 2797 articles were reviewed for eligibility. Of these, 367 were retrieved for full-text assessment and 139 were subsequently included for review. Seventy-four (53%) articles were original research, predominantly randomized controlled trials (n = 52 [37%]), whereas 58 (42%) were narrative reviews and seven (5%) were guidelines. Amongst original studies, pharmacologic strategies were the most commonly studied intervention (n = 42 [57%]). Additional deprescribing strategies included psychological therapies (n = 10 [14%]), mixed interventions (n = 12 [16%]), and others (n = 10 [14%]). Behaviour change interventions were commonly combined and included enablement (n = 56 [76%]), education (n = 36 [47%]), and training (n = 29 [39%]). Gradual dose reduction was frequently a component of studies, reviews, and guidelines, but methods varied widely. CONCLUSIONS Approaches proposed for deprescribing benzodiazepines and Z-drugs are numerous and heterogeneous. Current research in this area using methods such as randomized trials and meta-analyses may too narrowly encompass potential strategies available to target this phenomenon. Realist synthesis methods would be well suited to understand the mechanisms by which deprescribing interventions work and why they fail.

Abstract
BACKGROUND Medication safety for older persons represents an ongoing challenge. Inappropriate prescriptions--those with a high risk of evidence-based harm--persist in up to 25% of seniors, and account for a significant proportion of avoidable emergency department visits. This project is the sequel to the EMPOWER study, in which a novel consumer-targeted written knowledge transfer tool aimed at empowering older adults to act as drivers of benzodiazepine de-prescription resulted in a 27% reduction of inappropriate benzodiazepine use at 6-month follow-up (number needed to treat (NNT) = 4). Failure to discontinue in the EMPOWER study was attributable to re-emerging symptoms among participants, prescribing inertia, and lack of knowledge and skills for substituting alternate therapy among physicians and pharmacists. To maximize de-prescription of inappropriate therapy, educational medication-risk reduction initiatives should be tested that simultaneously include patients, physicians and pharmacists. The objective of this trial is to: 1) test the beneficial effect of a new de-prescribing paradigm enlisting pharmacists to transfer knowledge to both patients and prescribers in a 2-pronged approach to reduce inappropriate prescriptions, compared to usual care and 2) evaluate the transferability of the EMPOWER study concept to other classes of inappropriate prescriptions. METHODS We intend to conduct a 3-year pragmatic cluster randomized parallel-group controlled trial to test the effect of the new de-prescribing intervention compared to usual care for reducing 4 classes of inappropriate prescriptions from the 2012 Beers criteria among 450 community-dwelling older adults with polypharmacy. Inappropriate prescriptions will include benzodiazepines, sulfonylurea hypoglycemic agents, first generation antihistamines and non-steroidal anti-inflammatory drugs. The study population is community-dwelling older adults recruited from community pharmacies in Quebec, Canada. The intervention was developed based on a systematic review of the evidence for each medication. Participants in the experimental group will receive the written educational program following randomization and have their pharmacist send their physicians an evidence-based pharmaceutical opinion to recommend de-prescription and be followed for a year. The control group will be wait-listed for 6 months. DISCUSSION System change to effectively reduce medication risk among community-dwelling seniors requires a coordinated approach targeting physicians, pharmacists and patients. This trial will test the feasibility and effectiveness of a tripartite approach to de-prescribing. TRIAL REGISTRATION Registered via ClinicalTrials.gov on 31 January 2014, identifier: NCT02053194.

Abstract
BACKGROUND The use of benzodiazepines has been advised against in older people, but prevalence rates remain high. AIMS To review the evidence for interventions aimed at reducing benzodiazepine use in older people. METHOD We conducted a systematic review, assessment of risk of bias and meta-analyses of randomised controlled trials of benzodiazepine withdrawal and prescribing interventions. RESULTS Ten withdrawal and eight prescribing studies met the inclusion criteria. At post-intervention, significantly higher odds of not using benzodiazepines were found with supervised withdrawal with psychotherapy (odds ratio (OR) = 5.06, 95% CI 2.68-9.57, P<0.00001) and withdrawal with prescribing interventions (OR = 1.43, 95% CI 1.02-2.02, P = 0.04) in comparison with the control interventions treatment as usual (TAU), education placebo, withdrawal with or without drug placebo, or psychotherapy alone. Significantly higher odds of not using benzodiazepines were also found for multifaceted prescribing interventions (OR = 1.37, 95% CI 1.10-1.72, P = 0.006) in comparison with control interventions (TAU and prescribing placebo). CONCLUSIONS Supervised benzodiazepine withdrawal augmented with psychotherapy should be considered in older people, although pragmatic reasons may necessitate consideration of other strategies such as medication review.

An educational intervention to reduce the use of potentially inappropriate medications among older adults (EMPOWER study): protocol for a cluster randomized trial. Trials 2013; 14:80. [PMID: 23514019 PMCID: PMC3621099 DOI: 10.1186/1745-6215-14-80] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2012] [Accepted: 03/01/2013] [Indexed: 12/16/2022] Open
Abstract
Background Currently, far too many older adults consume inappropriate prescriptions, which increase the risk of adverse drug reactions and unnecessary hospitalizations. A health education program directly informing patients of prescription risks may promote inappropriate prescription discontinuation in chronic benzodiazepine users. Methods/Design This is a cluster randomized controlled trial using a two-arm parallel-design. A total of 250 older chronic benzodiazepine users recruited from community pharmacies in the greater Montreal area will be studied with informed consent. A participating pharmacy with recruited participants represents a cluster, the unit of randomization. For every four pharmacies recruited, a simple 2:2 randomization is used to allocate clusters into intervention and control arms. Participants will be followed for 1 year. Within the intervention clusters, participants will receive a novel educational intervention detailing risks and safe alternatives to their current potentially inappropriate medication, while the control group will be wait-listed for the intervention for 6 months and receive usual care during that time period. The primary outcome is the rate of change in benzodiazepine use at 6 months. Secondary outcomes are changes in risk perception, self-efficacy for discontinuing benzodiazepines, and activation of patients initiating discussions with their physician or pharmacist about safer prescribing practices. An intention-to-treat analysis will be followed. The rate of change of benzodiazepine use will be compared between intervention and control groups at the individual level at the 6-month follow-up. Risk differences between the control and experimental groups will be calculated, and the robust variance estimator will be used to estimate the associated 95% confidence interval (CI). As a sensitivity analysis (and/or if any confounders are unbalanced between the groups), we will estimate the risk difference for the intervention via a marginal model estimated via generalized estimating equations with an exchangeable correlation structure. Discussion Targeting consumers directly as catalysts for engaging physicians and pharmacists in collaborative discontinuation of benzodiazepine drugs is a novel approach to reduce inappropriate prescriptions. By directly empowering chronic users with knowledge about risks, we hope to imitate the success of individually targeted anti-smoking campaigns.

Abstract
SAMENVATTING: Benzodiazepinen worden frequent langdurig voorgeschreven voor de behandeling van angst en slaapproblemen, ondanks verschillende richtlijnen hiermee terughoudend te zijn. Deze richtlijnen zijn gebaseerd op de balans tussen de effectiviteit op langere termijn en de bijwerkingen (verslaving, anterograde amnesie en verhoogd risico op (onge)vallen en mortaliteit). De verslavende eigenschappen van benzodiazepinen blijken ook op te treden bij gebruik van laag-therapeutische doseringen. Hoewel aanvankelijk de aandacht uitging naar het optreden van ontwenningsverschijnselen bij staken, is de laatste decennia meer en meer aandacht gekomen voor de psychologische aspecten van deze verslaving. Recentelijk werd in dierexperimenteel onderzoek het effect van benzodiazepinegebruik op het beloningssysteem in de hersenen aangetoond. Wanneer langdurig benzodiazepinegebruik als probleem wordt onderkend door arts en patiënt blijken verschillende behandelmodaliteiten effectief. Eén op de vier langdurig gebruikers kan op eigen kracht stoppen na goede psycho-educatie en aanmoediging. Twee op de drie kunnen stoppen met behulp van systematische dosisreductie onder begeleiding van een arts of psycholoog. In geval van een onderliggende slaap- of angststoornis, verdient het aanbeveling deze laatste behandeling aan te vullen met cognitieve gedragstherapie. In tegenstelling tot wat vaak gedacht wordt, blijken ook de oudste ouderen goed te kunnen profiteren van deze behandelingen.

Abstract
Multilevel interventions, implemented at the individual, physician, clinic, health-care organization, and/or community level, increasingly are proposed and used in the belief that they will lead to more substantial and sustained changes in behaviors related to cancer prevention, detection, and treatment than would single-level interventions. It is important to understand how intervention components are related to patient outcomes and identify barriers to implementation. Designs that permit such assessments are uncommon, however. Thus, an important way of expanding our knowledge about multilevel interventions would be to assess the impact of interventions at different levels on patients as well as the independent and synergistic effects of influences from different levels. It also would be useful to assess the impact of interventions on outcomes at different levels. Multilevel interventions are much more expensive and complicated to implement and evaluate than are single-level interventions. Given how little evidence there is about the value of multilevel interventions, however, it is incumbent upon those arguing for this approach to do multilevel research that explicates the contributions that interventions at different levels make to the desired outcomes. Only then will we know whether multilevel interventions are better than more focused interventions and gain greater insights into the kinds of interventions that can be implemented effectively and efficiently to improve health and health care for individuals with cancer. This chapter reviews designs for assessing multilevel interventions and analytic ways of controlling for potentially confounding variables that can account for the complex structure of multilevel data.

Abstract
BACKGROUND Medication prescribing is a complex process where the focus tends to be on starting new medication, changing a drug regimen, and continuing a drug regimen. On occasion, a prudent approach to prescribing may necessitate ending an ongoing course of medication, either because it should not have been started in the first place; because its continued use would cause harm; or because the medication is no longer effective. OBJECTIVE To identify effective strategies for stopping pre-existing prescribing in situations where continued prescribing may no longer be clinically warranted. RESEARCH DESIGN Systematic searches for English-language reports of experimental and quasi-experimental research were conducted in PubMed (1951-November 2009), EMBASE (1966-September 2008), and International Pharmaceutical Abstract b (1970-September 2008). A manual search for relevant review articles and a keyword search of a local database produced by a previous systematic search for prescribing influence and intervention research were also conducted. STUDY SELECTION AND DATA EXTRACTION Following initial title screening for relevance 2 reviewers, using formal assessment and data extraction tools, independently assessed abstracts for relevance and full studies for quality before extracting data from studies selected for inclusion. RESULTS Of 1306 articles reviewed, 12 were assessed to be of relevant, high-quality research. A variety of drugs were examined in the included studies with benzodiazepines the most common. Studies included in the review tested 9 different types of interventions. Effective interventions included patient-mediated interventions, manual reminders to prescribers, educational materials given to patients, a face-to-face intervention with prescribers, and a case of regulatory intervention. Partially effective interventions included audit and feedback, electronic reminders, educational materials alone sent to prescribers, and distance communication combined with educational materials sent to prescribers. CONCLUSIONS It appears possible to stop the prescribing of a variety of medications with a range of interventions. A common theme in effective interventions is the involvement of patients in the stopping process. However, prescribing at the level of individual patients was rarely reported, with data often aggregated to number of doses or number of drugs per unit population, attributing any reduction to cessation. Such studies are not measuring the actual required outcome (stopping prescribing), and this may reflect the broader ambiguity about when or why it might be important to end a prescription. Much more research is required into the process of stopping pre-existing prescribing, paying particular attention to improving the outcomes that are measured.

Predictors of the incidence and discontinuation of long-term use of benzodiazepines: a population-based study. Drug Alcohol Depend 2009; 104:140-6. [PMID: 19515515 DOI: 10.1016/j.drugalcdep.2009.04.017] [Citation(s) in RCA: 80] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2008] [Revised: 04/23/2009] [Accepted: 04/24/2009] [Indexed: 11/21/2022]
Abstract
Long-term use of benzodiazepines (BZDs) has been linked with an array of negative health consequences and increased medical costs and social burden. In this study, we sought to investigate the factors accounting for differential risks in the process from incident BZD use to long-term use and discontinuation in the general population. On the basis of a random sample of 187,413 people enrolled in Taiwan's National Health Insurance program on January 1, 2000, data of 2000-2002 healthcare and pharmacological services utilization were retrieved. Long-term use (LTU) was defined by having received BZD prescriptions for 180 or more days within any given calendar year. Multivariate logistic regression analyses were carried out to assess the strength of associations while adjusting for the effects of individual sociodemographics, service providers, and pharmacological agents simultaneously. Results indicated that males, elderly, and those with physical or mental disorders were more likely to become long-term users of BZDs. Having received BZD prescriptions in multiple pharmacological agents, short-acting or mixed-type agents, and hypnotic indication were associated with a roughly 2- to 5-fold increased risk of BZD LTU soon after prescription initiation. With respect to discontinuation, the effects of pharmacological characteristics seem more salient as compared to those of individual and service-provider factors. Future strategies targeting individual factors and modifying service-provider prescription behaviors may be considered to reduce possible negative consequences of BZD LTU.
