Discontinuing benzodiazepines: best practices

Discontinuation of benzodiazepines and Z-drugs in hospitalised population at the age of 60 and above. An open-label randomized controlled trial

BACKGROUND

Treating insomnia with hypnotic drugs in elderly patients has many adverse effects. This study aims to assess the effect of two discontinuation methods of hypnotic drugs during acute hospitalization.

METHODS

We conducted an open-label randomized controlled trial that included participants aged 60 and above taking benzodiazepines or Z-Drugs for at least 3 months as a treatment for insomnia and were admitted to the hospital. In the prospective arm, patients were randomly assigned into two intervention groups. In the Minimal Intervention (MI) group, patients received an explanation of the dangers of long-term treatment and a recommendation to stop the treatment. In the Tapering Down Intervention (TDI) group, in addition to the explanation, patients received a tapering down table. In the retrospective arm (control group), we examined the use of hypnotic drugs among hospitalized patients 3 months after hospitalization, similar to the patients in the prospective arm.

RESULTS

46 patients were enrolled in the MI group, 55 patients in the TDI group, and 114 patients in the control group. The mean age in the three groups was 75.0 ± 8.2, 75.9 ± 9.0, and 75.0 ± 7.9 years respectively (p = 0.85). After 3 months, seven (15.2%) of the patients in the MI group, 15 (27.3%) in the TD group, and 2 (1.8%) in the control group (p = 0.00003) were weaned from the hypnotic drugs treatment, without a significant difference between the intervention groups (p = 0.221).

CONCLUSIONS

A short intervention during hospitalization results in a significant decrease in hypnotic drug use.

Surviving Benzodiazepines: A Patient's and Clinician's Perspectives

Although benzodiazepines have been used for 6 decades, many questions remain unanswered by research. The lived experiences of those adversely affected long term can provide insights into how these agents might be more thoughtfully prescribed. Here, perspectives of one such experience encompassing benzodiazepine initiation, ongoing use with adverse consequences and difficult discontinuation are presented through the eyes of an affected individual and a clinician. This experience highlights the importance of limited initiation and duration of use (2–4 weeks) as well as a supported, slow tapering process led by patients. Because researched evidence about deprescribing benzodiazepines is insufficient and because individual experiences vary so widely, it is the patient’s expertise—that of her or his lived experience—that should assume a primary role in determining the course and pace of discontinuing these medications.

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

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

Long-term risk of hip or forearm fractures in older occasional users of benzodiazepines

AIMS

This article sought to study the association between patterns of benzodiazepine (BZD) use and the risk of hip and forearm fractures in people aged 50 and 75 years or more.

METHODS

In a representative cohort of the French National Health Insurance Fund of individuals aged 50 years or older (n = 106 437), we followed up BZD dispensing (reflecting their patterns of use) and the most frequent fall-related fractures (hip and forearm) for 8 years. We used joint latent class models to simultaneously identify BZD dispensing trajectories and the risk of fractures in the entire cohort and in those 75 years or older). We used a survival model to estimate the adjusted hazard ratios (aHRs) between these trajectories and the risk of fractures.

RESULTS

In the entire cohort, we identified 5 BZD trajectories: non-users (76.7% of the cohort); occasional users (15.2%); decreasing users (2.6%); late increasing users (3.0%); and early increasing users (2.4%). Compared with non-users, fracture risk was not increased in either occasional users (aHR = 0.99, 95% confidence interval [CI] 0.99-1.00) or in decreasing users (aHR = 0.90, 95% CI 0.74-1.08). It was significantly higher in early increasing users (aHR = 1.86, 95% CI 1.62-2.14) and in late increasing users (aHR = 1.39, 95% CI 1.15-1.60). We observed similar trajectories and risk levels in the people older than 75 years.

CONCLUSION

Occasional BZD use, which is compatible with current recommendations, was not associated with an excess risk of the most frequent fall-related fractures in people older than 50 or 75 years.

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

BACKGROUND AND AIMS

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

METHODS

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

RESULTS

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

CONCLUSIONS

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