The Association Between Benzodiazepine Use and Depression Outcomes in Older Veterans

Intentional benzodiazepine poisoning in older adults reported to United States Poison Centers

INTRODUCTION

Despite known contraindications, benzodiazepines are frequently prescribed for older adults. This study utilizes poison control center data on benzodiazepine-involved cases aged 50 and above to compare the characteristics of suspected suicide attempt with other intentional misuse cases. We also examined associations of major medical outcomes (major effect/death) with demographic characteristics and other co-used substances in each group.

METHODS

The study employed data from the America's Poison Center National Poison Data System from 2015-2022. Descriptive statistics and binary logistic regression models were used.

RESULTS

Of the benzodiazepine-poisoning cases of intentional misuse (n = 93,245), 85 percent were suicide attempts and 15 percent were other intentional misuses. Reports to poisons centers showed a decline from 2019-2022 when compared to 2015-2016. However, the likelihood of a reported suicide attempt, compared to other intentional misuse, was greater in 2019-2022 compared to 2015-2016 and among those who co-used antidepressants, anxiolytics, atypical antipsychotics, other benzodiazepines, other analgesics, anticonvulsants, and alcohol. The odds of major effect/death in both groups were also greater in 2019-2022, with suicide attempt cases in advanced ages showing higher odds. The co-use of antidepressants, prescription opioids, atypical antipsychotics, anticonvulsants, and other analgesics were associated with a higher likelihood of major effect/death in both exposure groups. For instance, adjusted odds ratios for co-used prescription opioids were 2.20 (95 percent confidence intervals: 2.09-2.31) among suicide attempt cases and 3.51 (95 percent confidence intervals: 3.10-3.97) among other intentional misuse cases.

DISCUSSION

Healthcare providers need to screen for suicidal ideation among benzodiazepine users, with special attention to an increased risk of suicide attempt among those who co-use antidepressants and opioids and to decreasing adverse outcomes in all misuse cases. Assessments of underlying mental health and substance use problems and medication regimens to minimize polypharmacy and drug interactions are needed to reduce adverse outcomes.

CONCLUSIONS

Though the numbers of benzodiazepine-involved suicide attempt and other intentional misuse cases reported to United States poison centers decreased in recent years, the likelihood of major medical effect/death among these cases have increased.

Effects of traditional Chinese exercise on sleep quality: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

The efficacy of traditional Chinese exercise (TCE)-based interventions in the improvement of sleep quality is controversial. In this systematic review, we aimed to summarize randomized controlled trials (RCTs) that outline the effects of TCE on sleep quality.

METHODS

Five databases (Web of Science, Embase, PubMed, Medline, and China National Knowledge Infrastructure) were searched for literature published before July 2022. RCTs examining TCE interventions were included. The treatment effects were estimated using a random-effect meta-analysis model with mean differences (MDs). There were 2 outcome scales for sleep quality; however, because they were extremely contrastive to be analyzed by standard MD, the scales were analyzed separately to ensure the accuracy of the results. This review was registered in the International Prospective Register of Systematic Reviews (identifier CRD42023421314).

RESULTS

Twenty studies were included for analysis at last. The outcome was calculated using the Verran and Snyder-Halpern Sleep Scale (MD: 344.17, 95% confidence interval: 316.95 to 371.39, P < .00001) and Pittsburgh Sleep Quality Index to measure sleep quality (MD: -2.24, 95% confidence interval: -3.05 to -1.43, P < .00001), both showed improvement effect. In subgroup analysis, for patients with fibromyalgia, normal older adults, and non-Hodgkin lymphoma, chronic fatigue syndrome-like illness, knee osteoarthritis, nasopharyngeal carcinoma, pausimenia, insomnia, TCE could improve sleep quality. However, there was no significant improvement in stroke patients, breast cancer patients, normal college students, and episodic migraine patients. Tai Chi had greater effects in improving sleep quality than Qigong. In addition, the participants practice site, duration, and age did not influence the effects of TCE.

CONCLUSION

TCE can improve sleep quality in specific populations in specific populations clinical applications. Tai chi should be considered first to improve sleep quality. However, further extensive trials and rigorous study designs should be conducted to strengthen the findings of this study. In addition, considering the large heterogeneity, the findings of our study should be interpreted cautiously.

Delirium and Previous Psychiatric History Independently Predict Poststroke Posttraumatic Stress Disorder

OBJECTIVES

Delirium is an acute brain dysfunction that has been correlated with adverse mental health outcomes, such as depression and posttraumatic stress disorder (PTSD). However, delirium has not been studied in relation to mental health outcomes after cerebrovascular events. This study aimed to examine the incidence of PTSD after nontraumatic intracerebral hemorrhage (ICH) and identify new predictors of poststroke PTSD symptoms.

METHODS

Clinical data were collected from 205 patients diagnosed with nontraumatic ICH. Demographics and hospital course data were examined. Univariate and multivariable correlational analyses were performed to determine predictors of PTSD symptoms. PTSD symptoms were assessed using PTSD checklist-civilian version (PCL-C) scores.

RESULTS

Diagnostic criteria for a positive PTSD screen (PCL-C score ≥44) were met by 13.7%, 20.2%, and 11.6% of nontraumatic patients with ICH at 3, 6, and 12 months, respectively. On univariate analysis, younger age, female sex, unemployed, and in-hospital delirium were correlated with higher PCL-C scores. In multivariable models, younger age, female sex, unemployed, in-hospital delirium, and a previous anxiety or depression diagnosis were associated with higher PCL-C scores at different follow-up times. Modified Rankin Scale scores were also positively correlated with PCL-C scores at each time point.

CONCLUSIONS

Delirium, previous psychiatric history, younger age, female sex, and unemployment status were found to be associated with a greater degree of posthemorrhagic stroke PTSD symptoms. More significant PTSD symptoms were also correlated with greater functional impairment. A better understanding of patient susceptibility to PTSD symptoms may help providers coordinate earlier interventions.

Geriatric Depression and Inappropriate Medication: Benefits of Interprofessional Team Cooperation in Nursing Homes

An investigation of inappropriate medication use in treatment of depressivity in institutionalized older adults, based on a nurse-led evaluation of functional status and depressive symptoms in nursing home residents. Methods: A cross-sectional multicenter study was performed using records from 1087 residents cared for in fifteen nursing homes (NHs) in the Czech Republic. Inclusion criteria were being a permanent resident of one of the facilities, being 60 years of age or older, having a Geriatric Depression Scale score of 6 or more, and having a Mini Mental State examination score 10 or more. The final sample for analysis included 317 depressed NH residents. Results: 52 percent of NH residents with depressivity had no antidepressant treatment. Benzodiazepines were the only medication in 16 percent of depressed residents, and were added to antidepressant treatment in 18 percent of residents. Benzodiazepine users had significantly higher GDS scores compared to non-users (p = 0.007). Conclusion: More than half of depressed NH residents remained without antidepressant treatment. Residents inappropriately treated with benzodiazepines were more depressed than residents treated with antidepressants only, or even not treated at all. Cooperation of the interprofessional team in the screening of depressive symptoms has the potential to improve the quality of care.

Understanding the effects of chronic benzodiazepine use in depression: a focus on neuropharmacology

Benzodiazepines are frequently prescribed on an ongoing basis to individuals with depression, mainly to alleviate anxiety or insomnia, despite current guideline recommendations that continuous use should not exceed 4 weeks. Currently, there are no efficacy trials published beyond 8 weeks. Several antidepressant trials demonstrate that the concomitant use of a benzodiazepine is associated with poorer depressive outcomes and functional status; however, it is unclear why this is the case. Patients with depression receiving a benzodiazepine may reflect a more ill or high anxiety group, although even within anxiety disorders, the use of a benzodiazepine is associated with poorer outcomes. The neuroadaptive consequences of long-term benzodiazepine use may be a factor underlying these findings. Chronic benzodiazepine use results in decreased gamma-aminobutyric acid and monoaminergic function, as well as interference with neurogenesis, which are all purported to play a role in antidepressant efficacy. This review will discuss the oppositional neuropharmacological interactions between chronic benzodiazepine use and antidepressant mechanism of action, which could result in reduced antidepressant efficacy and function in depression.

Perceptions, clinical characteristics, and other factors associated with prolonged and high daily dose of benzodiazepine use among patients with anxiety or depressive disorders

BACKGROUND

Benzodiazepines (BZDs) have been widely used to treat anxiety; however, the risk of adverse health effects caused by their long-term use is high. This study examined the factors associated with the duration and higher daily dose of BZDs use among a population with anxiety or depressive disorders.

METHODS

A cross-sectional study design was used. Patients from a psychiatric outpatient department who had been prescribed BZDs were recruited. Data were collected from 250 patients.

RESULTS

Nearly 94% of patients were long-term BZDs users. The mean duration of BZDs use was 5.5 years; and mean defined daily dose (DDD) of BZDs use, converted to diazepam milligram equivalent (DDD), was 1.53 DME-DDD. Patients who knew more about alternative treatments were less prone to use BZD longer. Patients aged 65 years or older and those with difficulty falling asleep were more prone to use BZDs longer. Patients who were currently taking BZDs at higher daily dose were those who felt more depressed, prescribed second generation antipsychotics, suffered from disrupted sleep, less aware of alternative treatments, had comorbid chronic physical illness, and were current smokers.

LIMITATIONS

The cross-sectional study design limited its ability to confirm causal relationships.

CONCLUSIONS

Long-term and excessive daily dose of BZDs use in patients with depressive or anxiety disorders needs to be noted. Providing information or program of non-pharmacological treatment in reducing anxiety and improving specific sleep disturbance is suggested. Elderly, suffering from depressive mood, had comorbid chronic physical illness need to be targeted for further intervention.

Prescription of psychotropic medication in patients with type two diabetes mellitus: A multi-practice study from Ireland

Background: Comorbid anxiety and depression and type two diabetes mellitus (T2DM) are commonly managed by General Practitioners (GPs).

Objectives: To investigate the proportion of people with T2DM who are prescribed either antidepressant or benzodiazepine medications in general practice; to compare people with T2DM that have a prescription with those that do not in terms of patient characteristics, glycaemic control and healthcare utilization.

Methods: Anonymized data was collected by GPs and senior medical students from electronic medical records of patients with T2DM in 34 Irish general practices affiliated with the University of Limerick Graduate Entry Medical School during the 2013/14 academic year. Data included demographics, healthcare utilization, prescriptions and most recent glycosylated haemoglobin (HbA1c) measurement.

Results: The sample included 2696 patients with T2DM, of which 733 (36.7%) were female, and with a median age of 66 years. The percentage with a current prescription for an antidepressant or benzodiazepine was 22% (95%CI: 18.9–24.9). Those with a current prescription for either drug were more likely to have attended the emergency department (28.3% vs 15.7%, P <0.001), to have been admitted to hospital (35.4% vs 21.3%, P <0.001) in the past year and attend their GP more frequently (median of 9 vs 7, P <0.001) than those without a prescription. Rates of poor glycaemic control were similar in those with and without a current prescription.

Conclusion: Over one-fifth of people with T2DM in Irish general practice are prescribed an antidepressant or benzodiazepine medication. Prescription of these is associated with increased healthcare utilization but not poorer glycaemic control.

Concurrent benzodiazepine use in older adults treated with antidepressants in Asia

ABSTRACTBackground:Little is known about the combined use of benzodiazepines and antidepressants in older psychiatric patients. This study examined the prescription pattern of concurrent benzodiazepines in older adults treated with antidepressants in Asia, and explored its demographic and clinical correlates.

METHODS

The data of 955 older adults with any type of psychiatric disorders were extracted from the database of the Research on Asian Psychotropic Prescription Patterns for Antidepressants (REAP-AD) project. Demographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. Both univariate and multiple logistic regression analyses were performed.

RESULTS

The proportion of benzodiazepine and antidepressant combination in this cohort was 44.3%. Multiple logistic regression analysis revealed that higher doses of antidepressants, younger age (&lt;65 years), inpatients, public hospital, major comorbid medical conditions, antidepressant types, and country/territory were significantly associated with more frequent co-prescription of benzodiazepines and antidepressants.

CONCLUSIONS

Nearly, half of the older adults treated with antidepressants in Asia are prescribed concurrent benzodiazepines. Given the potentially adverse effects of benzodiazepines, the rationale of benzodiazepines and antidepressants co-prescription needs to be revisited.

Sedative-Hypnotic Use Among Older Adults Participating in Anxiety Research

Older adults are prescribed sedative-hypnotic medications at higher rates than younger adults. These are not recommended for older adults due to risk of sedation, cognitive impairment, and falls. Severe generalized anxiety disorder (GAD) is a possibly appropriate use of these medications in older people, but little is available on use of sedative-hypnotic medications among older adults with GAD. This study examined the frequency and predictors of sedative-hypnotic medication use among older adults screening positive for anxiety. 25.88% ( n = 125) of participants reported taking sedative-hypnotics over the past 3 months; 16.36% ( n = 79) reported taking benzodiazepines, and 12.22% ( n = 59) reported taking hypnotic sleep medications. Depressive symptoms were more strongly associated with sedative-hypnotic use than insomnia or worry. Major depressive disorder and posttraumatic stress disorder, but not GAD, predicted sedative-hypnotic use. Other medications and treatments are more appropriate and efficacious for depression, anxiety, and insomnia in this population.

Depression and Depression Treatment in a Population-Based Study of Individuals Over 60 Years Old Without Dementia

OBJECTIVE

To estimate the prevalence of depression in a population-based sample of older adults, and to identify the individual profile of people who received depression treatment.

DESIGN

Cross-sectional.

SETTING

Central area (Kungsholmen) in Stockholm, Sweden.

PARTICIPANTS

A randomized population-based sample of individuals aged 60 years and older (N = 3,084) without dementia from the Swedish National Study of Aging and Care in Kungsholmen examined between 2001 and 2004.

MEASUREMENTS

Experienced physicians carried out a semi-structured psychiatric examination including the Comprehensive Psychopathological Rating Scale. Depression was diagnosed according to DSM-IV-TR and DSM-5 criteria. Information regarding drug treatment and psychotherapy was collected during the examination and is based on self-report.

RESULTS

The prevalence of depression was 5.9% (major depression: 0.8%, minor depression: 5.1%). In the total sample, 8.3% were prescribed an antidepressant and 0.9% were treated with psychotherapy. Among individuals with depression, fewer than one-third received treatment with psychotherapy or antidepressants, but almost half were prescribed anxiolytic or hypnotic drugs. Individuals with self-reported depression and anxiety were more likely to receive depression treatment whereas individuals with depression who reported insomnia were less likely to receive depression treatment.

CONCLUSIONS

Our findings indicate that even in a central urban area of a country with an advanced healthcare system depression in old age is often unrecognized and untreated. In addition, almost half of those with depression received potentially inappropriate drug treatment with anxiolytics or hypnotics.
