Epidemic Use of Benzodiazepines among Older Adults in Israel: Epidemiology and Leverage Points for Improvement

Prevalence and clinical correlates of benzodiazepine use in the patients with major depressive disorder

BACKGROUND

Major depressive disorder (MDD) is a serious and disabling condition characterized by abnormal mood changes. Clinical guidelines for depression treatment recommend antidepressant medications, with benzodiazepines acting as short-term synergists. However, little is currently known about the prevalence and associated clinical risk factors of benzodiazepine use among Chinese patients with MDD. This study aimed to explore the prevalence and clinical risk factors associated with benzodiazepine use in this population.

METHODS

A total of 2742 patients with MDD (males/females = 816/1926, aged 14-60 years) participated in this cross-sectional observational study. General information and psychosis assessments were collected online. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), anxiety symptoms using the Generalized Anxiety Disorder-7 (GAD-7), and sleep problems and suicidal tendencies using the third and ninth items of the PHQ-9. Multivariable logistic regression analysis models were employed to identify factors associated with benzodiazepine use.

RESULTS

The prevalence of benzodiazepine use among patients with MDD was 42.9 %. Among these patients, 99.6 % used a single benzodiazepine, with oxazepam being the most frequently prescribed. Age, severity of sleep problems, depressive symptoms, and anxiety symptoms were significantly correlated with benzodiazepine use (all P < 0.001).

LIMITATIONS

The cross-sectional design of this study precludes establishing causal relationships.

CONCLUSION

Our findings indicate a high prevalence of benzodiazepine use among Chinese patients with MDD. Factors such as severe depressive symptoms, anxiety symptoms, age, and sleep problems appear to be associated with benzodiazepine use. These results underscore the importance of vigilance regarding benzodiazepine use in patients with MDD.

Hypnotic drug use and rehabilitation outcomes in post-acute geriatric hip fracture patients: A retrospective study

INTRODUCTION

The use of hypnotic drugs is common in the elderly and is associated with negative health outcomes. Our aim was to evaluate the prevalence of hypnotic drug usage amongst hip fracture patients undergoing a rehabilitation program and investigate any potential associations between hypnotic drug use and rehabilitation outcomes in a post-acute care setting.

METHODS

A retrospective analysis of 440 geriatric hip fracture patients was conducted from 1/1/2019 to 12/2021 in a geriatric rehabilitation center. The main outcome measures were the Functional Independence Measure (FIM), the motor FIM effectiveness and length of stay (LOS).

RESULTS

Two hundred and twenty-eight (51.7 %) patients out of the entire cohort (440)), were prescribed hypnotic drugs. These patients exhibited a significantly lower rate of diabetes (p = 0.025), a higher rate of depression (p = 0.003), and lower albumin levels (p = 0.023) upon admission to rehabilitation in comparison to untreated patients. No significant differences were observed between the two patient groups in functional rehabilitation outcomes or LOS. Moreover, no correlation was established between the hypnotic drug burden during rehabilitation and the outcome measures. Furthermore, no significant differences were found between patients treated with hypnotic drugs on admission and those who were prescribed these drugs during rehabilitation. The type of hypnotic drug did not affect these results.

CONCLUSION

The use of hypnotic drugs by elderly individuals undergoing a rehabilitation program after a hip fracture is unlikely to have an adverse impact on their short-term rehabilitation outcomes. Consequently, there may not be an immediate necessity to discontinue these drugs upon admission. Nevertheless, the use of hypnotic drugs should be approached with caution and minimized whenever possible due to an increased fall risk and other adverse effects.

Prescribing Benzodiazepines and Opioids and Clinical Characteristics Associated With 30-Day Hospital Return in Patients Aged ≥75 Years: Secondary Data Analysis

PURPOSE

The current study compared prevalence of opioid or benzodiazepine (BZD) prescription and co-prescription of opioids and BZD at discharge and return to a community hospital within 30 days, as well as identified clinical characteristics associated with hospital return in patients aged ≥75 years.

METHOD

A secondary analysis of a database created during implementation of the Safe Transitions for At Risk Patients program at a 400-bed community teaching hospital in south Florida was conducted. Multivariable logistic regression analyses were performed to identify significant demographic and clinical characteristics associated with return to the hospital within 30 days of discharge.

RESULTS

A total of 24,262 participants (52.6% women) with a mean age of 85.3 (SD = 6.42) years were included. More than 20% in each central nervous system prescription group (i.e., opioids only, BZD only, opioids and BZD) returned to the hospital within 30 days of discharge. Demographic and chronic conditions (e.g., congestive heart failure, chronic obstructive pulmonary disease, diabetes) and poly-pharmacy were significant factors of a 30-day return to the hospital.

CONCLUSION

Findings highlight the importance of hospital nurses' role in identifying high-risk patients, educating patients and caregivers, monitoring them closely, communicating with primary care physicians and specialists, and conducting intensive follow up via telephone to avoid 30-day rehospitalization.

Insights into patient characteristics and documentation of the use of sedative-hypnotic/anxiolytics in primary care: a retrospective chart review study

Background

Despite the known safety risks of long-term use of sedative-hypnotic/anxiolytic medications, there has been limited guidance for the safe and effective use of their chronic use in a primary care clinic setting. Understanding the characteristics of patients who receive sedative-hypnotic/anxiolytic medication and the clinical documentation process in primary care is the first step towards understanding the nature of the problem and will help inform future strategies for clinical research and practice.

Objectives

Characterize patients who received a sedative-hypnotic/anxiolytic prescription in primary care, and (2) gain an understanding of the clinical documentation of sedative-hypnotic/anxiolytic indication and monitoring in electronic medical records (EMR).

Methods

A random selection of patients who received a prescription for a benzodiazepine or Z-drug hypnotic between January 2014 and August 2016 from four primary care clinics in Winnipeg were included. Data was collected retrospectively using the EMR (Accuro®). Patient variables recorded included sex, age, comorbidities, medications, smoking status, and alcohol status. Treatment variables included drug type, indication, pattern of use, dose, adverse events, psychosocial intervention, tapering attempts, social support, life stressor, and monitoring parameters for sedative-hypnotic use. Demographic and clinical characteristics were described using descriptive statistics.

Results

Records from a sample of 200 primary care patients prescribed sedative-hypnotic/anxiolytics were analyzed (mean age 55.8 years old, 61.5% ≥ 65 years old, 61.0% female). Long-term chronic use (≥ 1 year) of a sedative-hypnotic/anxiolytic agent was observed in 29.5% of the sample. Zopiclone (30.7%) and lorazepam (28.7%) were the most common agents prescribed. Only 9.5% of patients had documentation of a past tapering attempt of their sedative-hypnotic/anxiolytic. The most common indications for sedative-hypnotic/anxiolytic use recorded were anxiety (33.0%) and sleep (18.0%), but indication was undetermined for 57.0% of patients. Depression (33.5%) and falls (18.5%) were reported by patients after the initiation of these agents.

Conclusions

A higher proportion of females and users 65 years and older received a prescription for a sedative-hypnotic/anxiolytic, consistent with previous studies on sedative-hypnotic use. We found inconsistencies in the documentation surrounding sedative-hypnotic/anxiolytic use. The indication for their use was unclear in a large number of patients. These findings will help us understand the state of the problem in primary care and inform future strategies for clinical research.

Promoting benzodiazepine cessation through an electronically-delivered patient self-management intervention (EMPOWER-ED): Randomized controlled trial protocol

Background

Long-term benzodiazepine dependence carries significant health risks which might be reduced with low-cost patient self-management interventions. A booklet version of one such intervention (Eliminating Medications Through Patient Ownership of End Results; EMPOWER) proved effective in a Canadian clinical trial with older adults. Digitizing such an intervention for electronic delivery and tailoring it to different populations could expand its reach. Accordingly, this article describes the protocol for a randomized controlled trial to test the effectiveness of an electronically-delivered, direct-to-patient benzodiazepine cessation intervention tailored to U.S. military veterans.

Methods

Design: Two-arm individually randomized controlled trial.

Setting

US Veterans Health Administration primary care clinics.

Participants

Primary care patients taking benzodiazepines for three or more months and having access to a smartphone, tablet or desktop computer.

Intervention and comparator

Participants will be randomized to receive either the electronically-delivered EMPOWER (EMPOWER-ED) protocol or asked to continue to follow provider recommendations regarding their benzodiazepine use (treatment-as-usual).

Measurements

The primary outcomes are complete benzodiazepine cessation and 25% dose reduction, assessed using administrative and self-report data, between baseline and six-month follow-up. Secondary outcomes are self-reported anxiety symptoms, sleep quality, and overall health and quality of life, measured at baseline and 6-month follow-up, and benzodiazepine cessation at 12-month follow-up.

Comments

This randomized controlled trial will evaluate whether the accessibility and effectiveness of a promising intervention for benzodiazepine cessation can be improved through digitization and population tailoring.

Adapting the Eliminating Medications Through Patient Ownership of End Results Protocol to Promote Benzodiazepine Cessation Among US Military Veterans: Focus Group Study With US Military Veterans and National Veterans Health Administration Leaders

Background

Long-term dependence on prescribed benzodiazepines is a public health problem. Eliminating Medications Through Patient Ownership of End Results (EMPOWER) is a promising self-management intervention, delivered directly to patients as a printed booklet, that is effective in promoting benzodiazepine reduction and cessation in older adults. EMPOWER has high potential to benefit large health care systems such as the US Veterans Health Administration (VHA), which cares for many veterans who use benzodiazepines for extended periods.

Objective

We aimed to adapt the original EMPOWER booklet materials for electronic delivery and for use among US military veterans receiving VHA care who were long-term benzodiazepine users.

Methods

We used elements of Analysis, Design, Development, Implementation, and Evaluation, a framework commonly used in the field of instructional design, to guide a qualitative approach to iteratively adapting EMPOWER Electronic Delivery (EMPOWER-ED). We conducted 3 waves of focus groups with the same 2 groups of VHA stakeholders. Stakeholders were VHA-enrolled veterans (n=16) with medical chart evidence of long-term benzodiazepine use and national VHA leaders (n=7) with expertise in setting VHA policy for prescription benzodiazepine use and developing electronically delivered educational tools for veterans. Qualitative data collected from each wave of focus groups were analyzed using template analysis.

Results

Themes that emerged from the initial focus groups included veterans’ anxiety about self-tapering from benzodiazepines and prior negative experiences attempting to self-taper without support. Participants also provided feedback on the protocol’s look and feel, educational content, the tapering protocol, and website functionality; for example, feedback from policy leaders included listing, on the cover page, the most commonly prescribed benzodiazepines to ensure that veterans were aware of medications that qualify for self-taper using the EMPOWER-ED protocol. Both groups of stakeholders identified the importance of having access to supportive resources to help veterans manage sleep and anxiety in the absence of taking benzodiazepines. Both groups also emphasized the importance of ensuring that the self-taper could be personalized and that the taper instructions were clear. The policy leaders emphasized the importance of encouraging veterans to notify their provider of their decision to self-taper to help facilitate provider assistance, if needed, with the taper process and to help prevent medication stockpiling.

Conclusions

EMPOWER-ED is the first direct-to-patient electronically delivered protocol designed to help US military veterans self-taper from long-term benzodiazepine use. We used the Analysis, Design, Development, Implementation, and Evaluation framework to guide the successful adaption of the original EMPOWER booklet for use with this population and for electronic delivery. The next step in this line of research is to evaluate EMPOWER-ED in a randomized controlled trial.

Evaluation of psychotropic medications use among elderly with psychiatric disorders in Saudi Arabia

AIMS

Potentially inappropriate psychotropic medications (PIPMs) prescribed to older adults with psychiatric disorders can inadvertently affect their health. The use of standards and guidelines can ensure prudent prescribing and minimize the risk of morbidities. This study assessed the pattern and prevalence of prescription of PIPMs to older individuals in outpatient psychiatric settings in Saudi Arabia, using the updated 2015 Beers criteria, as well as the probability of polypharmacy.

METHODS

The study was conducted in the outpatient psychiatric clinics of the only psychiatric hospital in Jazan region of Saudi Arabia. A retrospective cross-sectional review of electronic medical records was undertaken during 2018 to assess PIPM use and psychotropic polypharmacy. Descriptive statistics were generated and associations between PIPM use and baseline characteristics were assessed using multivariable logistic regression.

RESULTS

Overall, 68% of 1300 older adults received PIPMs, and 77.7% were on psychotropic polypharmacy. Amitriptyline, chlorpromazine, and trifluoperazine were extensively prescribed. Paroxetine (1.2%) and benzodiazepines were prescribed to a smaller proportion of the patients. Elderly with schizophrenia (AOR = 0.046, p < 0.001) and anxiety (AOR = 0.530, p = 0.036) were significantly less likely to have PIPMs than those with dementia. Likewise, elderly with depression and anxiety were less likely to have psychotropic polypharmacy as compared to those with dementia.

CONCLUSION

A substantial number of the elderly received PIPMs possibly based on implicit criteria. It is therefore important to provide mental health care providers in the region with educational programs to increase their awareness of PIPMs.

The prevalence and prescribing patterns of benzodiazepines and Z-drugs in older nursing home residents in different European countries and Israel: retrospective results from the EU SHELTER study

Background

Benzodiazepines (BZDs) and Z-drugs have high potential for developing frequent adverse drug events in older adults (e.g., psychomotor sedation, drug-related dementia, deliria, drug dependence, etc.). Knowledge of the prevalence and patterns of the use of BZDs/Z-drugs in vulnerable older patients is important in order to prevent and reduce the burden caused by their drug-related complications. Our study focused on international comparisons of the prevalence, country-specific prescribing patterns and risk factors of regular BZD/Z-drug use in nursing home (NH) residents.

Methods

This cross-sectional study retrospectively analysed data of 4156 NH residents, prospectively assessed in the Services and Health in the Elderly in Long TERm care (SHELTER) project conducted from 2009 to 2014. Residents aged 65+ in 57 NHs in 7 European countries and Israel were assessed by the InterRAI Long-Term Care Facilities instrument. Descriptive statistics and multiple logistic regression models were used to describe the country-specific prevalence, patterns and risk factors of BZD/Z-drug use.

Results

The mean age of the participants was 83.4 ± 9.4 years, 73% were female and 27.7% used BZDs/Z-drugs. The prevalence of BZD/Z-drug use differed significantly across countries, ranging from 44.1% in Israel to 14.5% in Germany. The most frequently prescribed were zopiclone (17.8%), lorazepam (17.1%) and oxazepam (16.3%). Lorazepam, oxazepam and diazepam were used in most of the countries. Brotizolam, temazepam and zolpidem showed highest prevalence in Israel (99.4% of all regular users of this medication in the sample), the Netherlands (72.6%) and France (50.0%), respectively. Residing in Israel was the most significant factor associated with the use of BZDs/Z-drugs or BZDs only (odds ratio [OR] 6.7; 95% confidence interval [CI] 4.8–9.2 and OR 9.7, 95%CI 6.5–14.5, respectively). The use of Z-drugs only was most significantly associated with residing in France (OR 21.0, 95%CI 9.0–48.9).

Conclusions

Despite global recommendations and warnings, the preference for and extent of use of individual BZDs and Z-drugs in vulnerable NH residents differ significantly across countries. The strong association with country of residence compared to clinical and functional factors denotes that prescribing habits, social, cultural, behavioural, and regulatory factors still play an important role in the current diverse use of these medications.

Reducing prescribing of benzodiazepines in older adults: a comparison of four physician-focused interventions by a medical regulatory authority

BACKGROUND

The inappropriate and/or high prescribing of benzodiazepine and 'Z' drugs (BDZ +) is a major health concern. The purpose of this study was to determine whether physician or pharmacist led interventions or a simple letter or a personalized prescribing report from a medical regulatory authority (MRA) was the most effective intervention for reducing BDZ + prescribing by physicians to patients 65 years of age or older.

METHODS

This was a four-armed, one year, blinded, randomized, parallel-group, investigational trial in Alberta, Canada. Participants were fully licensed physicians (n = 272) who had prescribed 4 times the defined daily dose (4 + DDD) or more of any BDZ + to an older patient at least once in the 3rd quarter of 2016. All physician-participants were sent a personalized prescribing profile by the MRA. They were then randomized into four groups that received either nothing more, an additional personal warning letter from the MRA, a personal phone call from an MRA pharmacist or a personal phone call from an MRA physician. The main outcomes were prescribing behavior change of physicians at one year in terms of: change in mean number of older patients receiving 4 + DDD BDZ + and mean dose BDZ + prescribed per physician. To adjust for multiple statistical testing, we used MANCOVA to test both main outcome measures simultaneously by group whilst controlling for any baseline differences.

RESULTS

All groups experienced a significant fall in the total number of older patients receiving 4 + DDD of BDZ + by about 50% (range 43-54%) per physician at one year, and a fall in the mean dose of BDZ + prescribed of about 13% (range 10-16%). However, there was no significant difference between each group.

CONCLUSIONS

A personalized prescribing report alone sent from the MRA appears to be an effective intervention for reducing very high levels of BDZ + prescribing in older patients. Additional interventions by a pharmacist or physician did not result in additional benefit. The intervention needs to be tested further on a more general population of physicians, prescribing less extreme doses of BDZ + and that looks at more clinical and healthcare utilization outcomes.

Drug Safety of Benzodiazepines in Asian Patients With Chronic Obstructive Pulmonary Disease

Purpose: Many comorbidities, including depression, anxiety, and insomnia, occur in patients with chronic obstructive pulmonary disease (COPD). These patients may be prescribed benzodiazepines (BZDs). However, there are some concerns that benzodiazepines increase the risk of drug overdose, hypercapnic respiratory failure, acute exacerbation and increased mortality. The aim of our study was to evaluate the drug safety of BZDs in patients with COPD. Methods: We used the National Health Insurance Research database in Taiwan from 2002 to 2016 to perform a retrospective cohort study. We enrolled patients who were exposed to the first prescription of BZDs, non-BZDs or a combination (mix user) after COPD diagnosis. We performed 1:1:1 propensity score matching in three groups. The outcomes were COPD with acute exacerbation and all-cause mortality. Poisson regression analysis was performed to evaluate the incidence rate ratios for the outcomes in the groups. Results: After propensity score matching, there were 2,856 patients in each group. After adjusting for confounding factors, we found that compared to BZD users, non-BZD and mix users had nonsignificant differences in outpatient management of acute exacerbations, hospitalization management of acute exacerbations, emergency department management of acute exacerbations and all-cause mortality. BZD and mix groups showed significantly increased admission for acute exacerbation of COPD compared with that of the nonuser group, with IRRs of 2.52 (95% CI, 1.52-4.18; p = 0.0004) and 2.63 (95% CI, 1.57-4.40; p = 0.0002), respectively. Conclusion: BZD, non-BZD, and mix users showed increased COPD-related respiratory events compared to nonusers in Asian subjects.

Relationship Between Changes in Sedative-Hypnotic Medications Burden and Cognitive Outcomes in Hospitalized Older Adults

BACKGROUND

Sedative-hypnotic medications (SHMs) are frequently used in hospitalized older patients, despite undesirable effects on cognitive status. Although previous studies found a significant number of patients experience changes in SHM use during hospitalization, it is unclear which pattern of change leads to hospital-associated cognitive decline (HACD). This study tested the association between patterns of SHM change and HACD.

METHODS

This secondary analysis study included 550 patients age 70+ who were cognitively intact at admission (Short Portable Mental Status Questionnaire [SPMSQ] ≥8). HACD was defined as at least 1-point decline in SPMSQ between admission and discharge. Changes in sedative burden (SB) before and during hospitalization (average SB of all hospitalization days) were coded using the Drug Burden Index sorting study participants into four groups: without SB (n = 254), without SB changes (n = 132), increased SB (n = 82), and decreased SB (n = 82).

RESULTS

Incidence of HACD was 233/550 (42.4%). In multivariate logistic analysis controlling for demographic characteristics, length of stay, severity of acute illness, comorbidity, SB score at home, pain on admission and depression, the odds of HACD were 2.45 (95% CI: 1.16 to 5.13) among participants with increased SB, 2.10 (95% CI: 1.13 to 3.91) among participants without SB changes, compared with participants with decreased SB.

CONCLUSION

Older patients whose SB is increased or does not change are at higher risk for acquired cognitive decline than are those whose SB is reduced. Identifying patients with a potential increase in SB and intervening to reduce it may help to fight HACD.

Prevalence of and pathways to benzodiazepine use in Brazil: the role of depression, sleep, and sedentary lifestyle

Objective:

This study aimed to determine the prevalence of benzodiazepine (BZD) use in Brazil and to investigate the direct and indirect effects of alcohol consumption, sedentary lifestyle (SL), depressive symptoms (DS), and sleep dissatisfaction (SD) on BZD use.

Methods:

The Second Brazilian Alcohol and Drugs Survey (II BNADS) used stratified cluster probabilistic sampling to select 4,607 individuals aged 14 years and older from the Brazilian household population.

Results:

The lifetime and 12-month prevalence of BZD use was 9.8 and 6.1%, respectively. Older participants (age 40 and older) and women had higher rates. Alcohol use disorder, DS, and SD were significantly more prevalent in BZD users. The parallel multiple mediator model showed a positive direct effect of alcohol consumption on BZD use, with significant positive indirect effects of SL, SD, and DS as simultaneous mediators leading to higher BZD intake. Other statistically significant indirect pathways were DS alone, SD alone, and all of the above except SL.

Conclusion:

The prevalence of BZD use in Brazil is high compared to that of other countries. Knowledge of the main risk factors and pathways to consumption can guide prevention initiatives and underlie the development of better tailored and effective treatment strategies.

Healthcare disparities amongst vulnerable populations of Arabs and Jews in Israel

The complex nature of studying health and healthcare disparities in general, and in the context of the Israeli healthcare system in particular, is depicted in two recent IJHPR articles. The first examines Emergency Department (ED) waiting times in a tertiary children’s hospital and the second examines disparities in the health care for people with schizophrenia of an ethnic-national minority. Contrary to other Israeli studies on wide disparities in health and healthcare, these studies show no disparities -  ED waiting times did not differ among Arab and Jewish children and report no differences in performance of Hemoglobin A1C tests or in surgical interventions in patients with cardiovascular disease between Arabs and Jews with schizophrenia. Thus, the studies reflect areas of equitable health care delivery within the Israeli healthcare system.

Future studies should account for the fact that the phenomena of health and healthcare disparities is complex and should utilize rigorous methodologies to take into consideration the various factors that may affect the manifestation of differences amongst population groups. As a result, they may help detect disparities which may otherwise be missed.
