Long-term Benzodiazepine Use Research Articles

Long-term use of benzodiazepines and Z drugs: a qualitative study of patients' and healthcare professionals' perceptions and possible levers for change.

BackgroundAlthough long-term use of benzodiazepines (BZDs) and Z drugs is associated with various side effects, they remain popular among the older population. Possible reasons for this phenomenon could be ineffective ways of transmitting information on the health risks associated with long-term use, and communication gaps between patients and healthcare professionals.AimThe aim was to investigate the views of patients, physicians, nurses, and pharmacists regarding long-term BZD and Z drug use.Design & settingThe qualitative study design used focus group interviews with physicians, pharmacists, and nurses in Hamburg. Patient interviews were conducted in Lippstadt, Germany.MethodThe interviews were audiotaped with each participant’s permission, transcribed, and thematically analysed using a software program for qualitative research (MAXQDA).ResultsThe data from the four focus groups consisting of 28 participants were analysed. Patients indicated lack of knowledge about risks and side effects, difficult access to alternatives, and fears of ceasing drug use without professional support. Although the physicians were reported to be cautious about prescribing BZDs and Z drugs, the psychosocial problems of older patients are often considered to be complex and treatment knowledge, experience, and resources are frequently unsatisfactory. Nurses described that when BZDs were prescribed, they did not feel it was their responsibility to evaluate their effects. Pharmacists were reported to be strongly ambivalent in informing patients about the risks, which may contradict the prescription advice provided by the physician.ConclusionPatients, physicians, nurses, and pharmacists reported differences in the perception of long-term BZD and Z drug use. Nevertheless, all of the participants described lack of information and expressed the need for greater communication exchange.

Benzodiazepines Associated With Acute Respiratory Failure in Patients With Obstructive Sleep Apnea

Aims: Obstructive sleep apnea (OSA) and insomnia commonly coexist; hypnotics are broadly prescribed for insomnia therapy. However, the safety of hypnotics use in OSA patients is unclear. We conducted a retrospective case-control study to investigate the risk of adverse respiratory events in hypnotics-using OSA patients.Methods: We obtained data from the Taiwan National Health Insurance Database from 1996 to 2013. The case group included 216 OSA patients with newly diagnosed adverse respiratory events, including pneumonia and acute respiratory failure. The control group included OSA patients without adverse respiratory events, which was randomly frequency-matched to the case group at a 1:1 ratio according to age, gender, and index year. Hypnotics exposure included benzodiazepines (BZD) and non-benzodiazepines (non-BZD). A recent user was defined as a patient who had taken hypnotics for 1–30 days, while a long-term user was one who had taken hypnotics for 31–365 days.Results: Multivariable adjusted analysis showed recent BZD use is an independent risk for adverse respiratory events (OR = 2.70; 95% CI = 1.15–6.33; P < 0.001). Subgroup analysis showed both recent and long-term BZD use increased the risk of acute respiratory failure compared to never BZD use (OR = 28.6; 95% CI = 5.24–156; P < 0.001, OR = 10.1; 95% CI = 1.51–67.7; P < 0.05, respectively). Neither BZD nor non-BZD use increased the risk of pneumonia in OSA patients.Conclusion: BZD use might increase the risk of acute respiratory failure in OSA patients.

Risks of Benzodiazepines in Chronic Obstructive Pulmonary Disease with Comorbid Posttraumatic Stress Disorder.

Benzodiazepines are associated with mortality and poor outcomes among patients with chronic obstructive pulmonary disease (COPD), but use of benzodiazepines for dyspnea among patients with end-stage disease may confound this relationship. Assess the mortality risks of long-term benzodiazepine exposure among patients with COPD and comorbid post-traumatic stress disorder (PTSD), patients with chronic nonrespiratory indications for benzodiazepines. We identified all patients with COPD and PTSD within the Veteran's Health Administration between 2010 and 2012. We calculated propensity scores for benzodiazepine use and compared overall and cause-specific mortality of patients with long-term (≥90 d) benzodiazepine use relative to matched patients without use. Secondary analyses assessed propensity-adjusted survival by characteristics of benzodiazepine exposure. Among 44,555 eligible patients with COPD and PTSD, 23.6% received benzodiazepines long term. In the matched sample of 19,552 patients, we observed no mortality difference (hazard ratio [HR] for long-term use, 1.06; 95% confidence interval [CI], 0.95-1.18) but greater risk of death by suicide among those with long-term use (HR, 2.33; 95% CI, 1.14-4.79). Among matched and unmatched patients, short-term benzodiazepine use, but not long-term use, was associated with increased mortality (short-term: HR, 1.16; 95% CI, 1.05-1.28; long-term: HR, 1.03; 95% CI, 0.94-1.13). Risks for respiratory compromise related to long-term benzodiazepine use in COPD may be less than previously estimated, but short-term use of benzodiazepines could still pose a mortality risk. Suicide associated with benzodiazepine use in this population warrants further investigation.

The impact of in hospital patient-education intervention on older people's attitudes and intention to have their benzodiazepines deprescribed: a feasibility study.

Background:Long-term benzodiazepine use in the older population is common and is associated with significant harm. The provision of a patient-educational booklet during hospitalization may encourage patients to discuss review and possible deprescribing of benzodiazepine therapy with their health professionals. The aim of this study was to assess the feasibility and effect of a patient empowerment intervention in hospital inpatients on patient initiation of a discussion about deprescribing benzodiazepines versus usual care.Methods:A feasibility interventional study using a patient-empowerment education intervention was conducted at a Sydney teaching hospital. Patients aged ⩾ 65 years, prescribed a benzodiazepine, and able to provide consent were invited to participate in the study. Participants were randomly allocated to intervention or control group (1:1). Intervention participants received the patient-empowerment booklet and control received usual care. All participants received 1-month follow-up phone interviews to assess medication and attitudinal changes.Results:A total of 42 participants were recruited (20 intervention and 22 control). The average age was 71.5 (interquartile range: 69.0–80.3) and 54.8% were females. There was no difference in baseline characteristics between intervention and control groups (p > 0.05). At baseline, 65.0% of participants (53.0% intervention, 86.0% control) were not concerned about the potential benzodiazepine side effects. Twenty-nine participants (15 intervention and 14 control) completed 1-month follow up; 22 participants (11 intervention and 11 control) were discharged on the benzodiazepine. Among these, 13 (59.1%) had ceased benzodiazepine at 1-month follow up [46.2% (n = 6) intervention; 53.8% (n = 7) control]. In the intervention group, 33.3% (n = 5) of participants had initiated a discussion with their doctor or pharmacist about stopping the benzodiazepine compared with 35.7% (n = 5) in the control group.Conclusion:Cessation of benzodiazepines 1 month following discharge was common. Future larger studies are required to confirm the effectiveness of providing a patient-empowerment booklet on reducing benzodiazepine use and other potentially inappropriate medications.

Economic impact of potentially inappropriate prescribing and related adverse events in older people: a cost-utility analysis using Markov models

ObjectivesTo determine the economic impact of three drugs commonly involved in potentially inappropriate prescribing (PIP) in adults aged ≥65 years, including their adverse effects (AEs): long-term use of non-steroidal anti-inflammatory...

Withdrawal from long-term use of zopiclone, zolpidem and temazepam may improve perceived sleep and quality of life in older adults with primary insomnia.

Long-term use of benzodiazepines or benzodiazepine receptor agonists is widespread, although guidelines recommend short-term use. Only few controlled studies have characterized the effect of discontinuation of their chronic use on sleep and quality of life. We studied perceived sleep and quality of life in 92 older (age 55-91years) outpatients with primary insomnia before and after withdrawal from long-term use of zopiclone, zolpidem or temazepam (BZDA). BZDA was withdrawn during 1month, during which the participants received psychosocial support and blindly melatonin or placebo. A questionnaire was used to study perceived sleep and quality of life before withdrawal, and 1month and 6months later. 89 participants completed the 6-month follow-up. As melatonin did not improve withdrawal, all participants were pooled and then separated based solely on the withdrawal results at 6months (34 Withdrawers. 55 Nonwithdrawers) for this secondary analysis. At 6months, the Withdrawers had significantly (P<0.05) shorter sleep-onset latency and less difficulty in initiating sleep than at baseline and when compared to Nonwithdrawers. Compared to baseline, both Withdrawers and Nonwithdrawers had at 6months significantly (P<0.05) less fatigue during the morning and daytime. Stress was alleviated more in Withdrawers than in Nonwithdrawers (P<0.05). Satisfaction with life and expected health 1year later improved (P<0.05) in Withdrawers. In conclusion, sleep disturbances, daytime fatigue and impaired quality of life may resolve within 6months of BZDA withdrawal. These results encourage withdrawal from chronic use of benzodiazepine-type hypnotics, particularly in older subjects.

Work-Related Stressors and Increased Risk of Benzodiazepine Long-Term Use: Findings From the CONSTANCES Population-Based Cohort.

Objectives. To examine whether stressful job exposure to the public could be associated with having long-term benzodiazepine use.Methods. From the participants included between 2012 and 2016 in the French population-based CONSTANCES cohort, 13 934 men and 19 261 women declared a daily job exposure to the public and rated the frequency of stressful exposure. We examined benzodiazepine long-term use by using drug reimbursement administrative registries. Logistic regressions provided odds ratios (ORs) of benzodiazepine long-term use, with stratification for gender and adjustment for age, education, and area deprivation index. Occupational grade, job strain, depression, self-rated health, and alcohol use disorder were additional stratification variables.Results. Benzodiazepine long-term use was positively associated with stressful exposure to the public ("often or always" vs "rarely or never") in men (OR = 2.2; 95% confidence interval [CI] = 1.8, 2.8) and women (OR = 1.6; 95% CI = 1.4, 1.9), with dose-dependent relationships (P trends < .001). Adjustments and analyses in subgroups without other individual or environmental vulnerability factors led to similar results.Conclusions. Stressful job exposure to the public increases the risk of benzodiazepine long-term use. Prevention programs aiming at reducing the burden of benzodiazepine long-term use would benefit in targeting this specific population.

Metformin produces anxiolytic-like effects in rats by facilitating GABAA receptor trafficking to membrane.

Altered function or expression of GABAA receptors contributes to anxiety disorders. Benzodiazepines are widely prescribed for the treatment of anxiety. However, the long-term use of benzodiazepines increases the risk of developing drug dependence and tolerance. Thus, it is urgent to explore new therapeutic approaches. Metformin is widely used to treat Type 2 diabetes and other metabolic syndromes. However, the role of metformin in psychiatric disorders, especially anxiety, remains largely unknown. We examined the effects of metformin on anxiety-like behaviour of rats in open field test and elevated plus maze test. We also observed the effect of metformin (10μM, in vitro; 100mg·kg-1 , in vivo) on the trafficking of GABAA receptors, as mechanisms underlying the anxiolytic effects of metformin. Metformin (100mg·kg-1 , i.p. 30min) displayed a robust and rapid anxiolytic effect, without tolerance. Metformin up-regulated the surface expression of GABAA receptors and increased miniature inhibitory postsynaptic currents (mIPSCs). AMP-activated protein kinase (AMPK) activated by metformin-induced stimulation of forkhead box O3a (FoxO3a) transcriptional activity, followed by increased expression of GABAA receptor-associated protein (GABARAP) and its binding to GABAA receptors finally resulted in the membrane insertion of GABAA receptors. Metformin increased mIPSCs by up-regulating the membrane insertion of GABAA receptors, via a pathway involving AMPK, FoxO3a, and the GABAA receptor-associated protein. Thus metformin has a potential new use in the treatment of anxiety disorders.

Concomitant use of benzodiazepines and opioids in community-dwelling older people with or without Alzheimer's disease-A nationwide register-based study in Finland.

The study aims to determine the prevalence of concomitant use of benzodiazepines and opioids among community-dwelling older people with or without Alzheimer's disease (AD). An additional aim was to describe the factors associated with prolonged concomitant use, and the most commonly used combinations of these drugs. This study utilized data from the register-based Medication Use and Alzheimer's disease (MEDALZ) study, including all community-dwelling residents of Finland who received a clinically verified AD diagnosis between 2005 and 2011 (n=70718) and their matched comparison persons without AD. After exclusion of individuals who were hospitalized throughout the follow-up, 69353 persons with and 69353 without AD were included in this study. Benzodiazepines and related drugs (BZDRs) were used by 28475 (41.1%) of those with and 24506 (35.3%) of those without AD. Prolonged (greater than or equal to 90days) concomitant use of BZDRs and opioids was more common among BZDR users without AD (N=3936; 16.1%) than among those with AD (N=2963; 10.4%). A shorter duration of concomitant use (1-89days) revealed similar results, N=3821; 15.6% and N=3008; 10.6%, respectively. Prolonged concomitant use of BZDRs and opioids was associated with female sex, low socioeconomic position, most of the common comorbidities and history of substance abuse or long-term benzodiazepine use. The most commonly used combinations were Z-drug (31.7%) or benzodiazepine (29.9%) with a weak opioid. Despite the recommendations and risks, the prevalence of concomitant BZDR and opioid use was common in older persons with or without AD. It is important to develop strategies to reduce unnecessary concomitant use of these drugs.

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

ObjectiveTo evaluate the efficacy of using electroacupuncture as an adjunct treatment in enhancing the benzodiazepine cessation rate in long-term benzodiazepine users. MethodsThis 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. ResultsThe 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. ConclusionsElectroacupuncture 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. Trial RegistrationClinicalTrials.gov # NCT02475538.

Reasons for Long-Term Use of Benzodiazepines and Z-Drugs in Older Patients

Long-term use of benzodiazepines (BZD) and Z-drugs is associated with the risk of developing dependency. Many older patients use these drugs for long durations, which is often associated with low-dose dependency without an increase in dose. The aim of this study is to investigate the reasons, symptoms, and side effects, as well as the prescription conditions among older patients who were prescribed BZD or Z-drugs within the last 12 months. A 9-page questionnaire was sent to 4,000 patients of the AOK-NordWest, stratified according to age group (50-56 years;>65 years) and intake behavior (long-term use/ guideline incompatible; short-term use/ guideline compatible). Patients provided demographic data and indicated on a comprehensive list of BZD and Z-drugs, which substances they had used or were currently using. In addition, patients were asked about the reasons and underlying symptoms for taking these medications, possible side effects, and previous attempts to discontinue the medications. A total of 466 patients returned completed questionnaires (11.7%). A further 43 privately insured patients were recruited through pharmacies. 169 patients, mainly from the group with guideline-compatible prescriptions, indicated that they had never taken these medications. The remaining 340 patients were 68.5% female and the average age was 72.1 years. Compared to patients with guideline-compatible prescriptions, a greater proportion of patients with guideline-incompatible prescriptions were taking Z-drugs. The average daily dose (DDD) consumed was significantly higher than in those with guideline-compatible prescriptions, although on average both patient groups took low doses (<1 DDD) of the medication. In both groups, the main reason for taking BZD and Z-drugs was sleeping problems. Considering the recommendation that BZD and Z-drugs are to be taken only short-term for sleeping problems, the extent of insomnia indications is high. The low doses suggest a careful and controlled prescription behavior in both groups, with the majority of long-term consumers likely to have developed low-dose dependency. This is associated with only a limited need for intervention, since only few medication-dependent people underwent addiction treatment.

Usages et mésusages de benzodiazépines hors France

Among 8countries included in the report of ANSM, France is second behind Spain, when defined daily doses (DDD) are considered. Few studies, recent and based on representative samples of population, investigated the use of benzodiazepines in other countries and data are limited to compare France and other countries. In most countries, the use of benzodiazepines increases with age and is more frequent in women than in men. Variations of benzodiazepines use that were observed in other countries are similar to those observed in France, with a slight decrease but persistent high levels of use. In most countries, the long-term use of benzodiazepines is stable over time even though simple use decreases.

Factors Associated With Long-term Benzodiazepine Use Among Older Adults

This cohort study evaluates factors associated with the transition to long-term benzodiazepine use among older adults newly prescribed this drug by a nonpsychiatric clinician.

Patterns of benzodiazepines use in primary care adults with anxiety disorders

BackgroundBenzodiazepines 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. MethodsData 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. ResultsBenzodiazepines 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. LimitationData collection with self-reported questionnaires may be subject to information bias. ConclusionsDespite 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.

Potentially inappropriate use of benzodiazepines and z-drugs in the older population-analysis of associations between long-term use and patient-related factors.

IntroductionThe long-term use of benzodiazepines (BZD) and z-drugs in older populations is associated with a variety of sociodemographic and health-related factors. Recent studies reported that long-term BZD and z-drugs use is associated with increased age, female sex, and severe negative psychological (e.g., depression) and somatic (e.g., chronic disease) factors. The current study explores the sociodemographic and health-related factors associated with long-term BZD and z-drugs use in the elderly.MethodsWe conducted a cross-sectional survey among randomly selected patients of one health insurance plan (“AOK North-West”) with BZD and z-drugs prescriptions in the past 12 months. The sample was stratified by appropriate German prescription guidelines (yes vs. no) and age (50–65 vs. >65 years). To examine the association of selected sociodemographic and psychological variables (e.g., sex, employment status, quality of life, depression) with long-term use, a binary logistic regression analysis was conducted.ResultsIn total, data from 340 patients were analyzed. The mean age was 72.1 (SD = 14.5) years, and the most commonly used substances were zopiclon (38.1%), oxazepam (18.1%), and lorazepam (13.8%). The mean defined daily dose (DDD) was 0.73 (SD = 0.47). Insomnia was the main reason for prescribing BZD and z-drugs. The long-term use of BZD and z-drugs was significantly associated with unemployment (OR = 2.9, 95% CI [1.2–7.1]) and generally problematic medication use (OR = 0.5, 95% CI [0.2–1.0]).DiscussionUnemployment status and problematic medication use had a significant association with the patient-reported, long-term use of BZD and z-drugs. Divergent prescription patterns might suggest problematic patterns of BZD and z-drugs use. The causal connection between the identified factors and problematic BZD and z-drugs prescription is not discussed in this paper. Nevertheless, employment status and possible evidence of general problematic drug use may be a warning signal to the prescribers of BZD and z-drugs.

Trends in the long-term use of benzodiazepine anxiolytics and hypnotics: A national register study for 2006 to 2014.

Long-term benzodiazepine (BZD) treatment continues to be a debated topic. Because individual BZDs have different clinical profiles, we assessed the nationwide trends of long-term BZD use at active substance level during years 2006 to 2014. This study covered all reimbursed BZD purchases (n=408572-521823 annually) for adults recorded in the Finnish Prescription Register. We assessed long-term use (annual cumulative purchase of ≥180 defined daily doses) in general, and at active substance level with the most commonly used BZD anxiolytics (oxazepam, diazepam, alprazolam, and clonazepam for nonepilepsy indications) and hypnotics (zopiclone, zolpidem, and temazepam) included. The persistence rates for each substance were assessed separately. The prevalence of long-term BZD use among Finnish adults declined significantly from 5.3% to 3.6%, during years 2006 to 2014. Despite this decline, there was a significant increase in the long-term use of clonazepam for nonepilepsy indications and zolpidem (28.0% and 17.5%, respectively). Long-term use was common in the aged population, as well as among the users of hypnotics or clonazepam. Persistent use of 9 consecutive calendar years varied between 7.5% for incident alprazolam users and 21.0% for incident clonazepam users. We found a declining trend in long-term BZD use, but the decline was not uniform between the substances-the long-term use of clonazepam and zolpidem even increased. Follow-up research is needed to assess whether the decline in BZD use is accompanied by an increased use of other types of anxiolytic or hypnotic drugs or other forms of treatment.

Benzodiazepinas e risco de demência: qual a evidência?

Aim: To determine if long-term use of benzodiazepines on people aged ≥ 65 years is associated with an increased dementia risk. Data sources: National Guideline Clearinghouse, NHS Evidence, CMA InfoBase, Cochrane, DARE, MEDLINE/PubMed. Review methods: Guidelines, systematic reviews, meta-analyses and observational studies in English and Portuguese, published between January of 2006 and March of 2016, were searched, using the MeSH terms ‘benzodiazepines’ and ‘dementia’. Strength of Recommendation Taxonomy (SORT) scale from the American Family Physician was applied to evaluate the levels of evidence (LE) and the strength of recommendation (SR). Results: There were obtained 209 articles and five of these met the inclusion criteria. The meta-analysis and systematic review revealed an association between benzodiazepines use and increased risk of dementia (LE 3). This risk increases with treatment duration, cumulative doses of benzodiazepines and benzodiazepines with long duration of action (LE 3). Nonetheless, observational studies did not reveal this association (LE 3). Conclusions: There is limited evidence (SR C) for the association between benzodiazepines use and risk of dementia. Therefore, more prospective cohort studies, with a long follow-up and adjusted for confounding variables, is needed to clarify the existence of a possible causal association and to decrease the reverse causality bias. However, the implementation of these studies presents several methodological difficulties. This study reinforces the already existing concern about the chronic use of benzodiazepines in the elderly population, in the treatment of anxiety and sleep disorders and emphasize the role of the Family Physician as a longitudinal health care provider.

Decreasing Trend in the Use and Long-Term Use of Benzodiazepines Among Young Adults.

Patterns of benzodiazepine (BZD) use and long-term use among young adults are not well known. Our aim was to study trends in BZD use and long-term use among 18-25-year-old young adults by gender and active substance in a nationwide retrospective longitudinal register-based setting. All Finns aged 18-25 years with reimbursed purchases of BZDs in 2006-2014 recorded to the Finnish Prescription Register were included. Annual prevalence rates of BZD use and long-term use among young adults were reported overall, according to gender, drug group (anxiolytic or hypnotic), and active substance. Long-term use of BZDs was defined as purchasing ≥180 Defined Daily Doses (DDDs) in at least two drug purchases during a calendar year. Overall prevalence of BZD use among young adults decreased from 24.0 to 18.8 users per 1000 inhabitants in 2006-2014. Prevalence of long-term use decreased from 5.5 to 3.3 users per 1000 inhabitants. Overall BZD use was higher among females, whereas long-term use was more common among males. Use of anxiolytics was more common than use of hypnotics. Oxazepam, alprazolam, zopiclone, and zolpidem were the most used BZDs, whereas alprazolam and clonazepam were the substances with most long-term use. The use and long-term use of BZDs have decreased annually since 2008 among Finnish young adults. Further research is needed to investigate the reasons behind the decline.

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.
