Benzodiazepine Receptor Agonists Use and Cessation Among Multimorbid Older Adults with Polypharmacy: Secondary Analysis from the OPERAM Trial

Barriers to Deprescribing Benzodiazepines in Older Adults in a Survey of European Physicians

Importance

The use of benzodiazepine receptor agonists (BZRA) poses serious health risks to older adults. Although several guidelines recommend deprescribing, implementation in clinical practice remains limited.

Objective

To identify physicians' barriers to and enablers of deprescribing BZRA in adults aged 65 years and older taking a BZRA for sleep problems; to determine factors associated with hospital physicians' intention to deprescribe BZRA and their self-reported routine BZRA deprescribing.

Design, Setting, and Participants

This survey study included hospital physicians and general practitioners (GPs) working across 6 European Countries (Belgium, Greece, Norway, Poland, Spain, and Switzerland) between December 2022 and March 2023.

Main Outcomes and Measures

Barriers identification via a 35-item questionnaire based upon the Theoretical Domains Framework (TDF). Responses were categorized as major barriers, moderate barriers, and enablers based on their mean scores. Multivariable logistic regressions were used to identify background characteristics and TDF-based domains associated with hospital physicians' intention to deprescribe and self-reported routine deprescribing.

Results

Questionnaires from 240 hospital physicians and 96 GPs were analyzed. Most participants were women: 144 (61.0%) hospital physicians and 52 (54.2%) GPs. In terms of experience, the most common reported time in practice was less than 5 years for hospital physicians (76 [31.7%]) and between 10 and 14 years for GPs (35 [36.5%]). Most reported deprescribing BZRA routinely (135 hospital physicians [57.2%] and 66 GPs [72.5%]). Major barriers (and TDF domains) were similar for hospital physicians and GPs across the 6 countries. These barriers included: lack of training (skills), low self-efficacy (beliefs about capabilities), prioritization of other health issues (goals), frustration with the challenges of deprescribing (emotions), insufficient staff and time, absence of local policies (environmental context and resources), and reluctance from patients (social influence). Intention to deprescribe was significantly associated with country, occupation type, and 5 TDF domains: memory, attention, and decision process (odds ratio [OR], 1.70; 95% Ci, 1.22-2.40); social and/or professional role and identity (OR, 5.92; 95% CI, 3.28-11.07); beliefs about capabilities (OR, 2.35; 95% CI, 1.55-3.63); beliefs about consequences (OR, 3.00; 95% CI, 1.61-5.71); and reinforcement (OR, 1.49; 95% CI, 1.05-2.15). Routine deprescribing was significantly associated with 3 TDF domains: memory, attention, and decision processes; intentions; and emotions.

Conclusion

In this theory-based survey study of physicians, physicians and general practitioners described numerous barriers to deprescribing BZRA in older adults. Our findings indicate that effective deprescribing efforts require approaches that address both reflective processes (eg, enhancing capability) and impulsive processes (eg, managing emotions).

Chronic benzodiazepine usage among older people: prevalence, indications, and treatment modifications in patients admitted to an acute geriatric unit

AIM

To investigate the prevalence and indications of benzodiazepines (BZD) usage among patients admitted to an acute geriatric unit and assess changes in prescriptions.

METHODS

BZD indications were documented reviewing clinical records, with appropriateness assessed based on the STOPP-START criteria. Changes in BZD prescriptions were recorded at discharge and 3 months later.

RESULTS

Among the 366 patients included (mean age: 92.8 years, 68% females), 91 (24.9%) were on BZD upon admission, being inappropriate in 93.4%. At discharge, BZD discontinuation was observed in 40.7% and dose reduction initiated in 57.4%. Among patients discharged without prescriptions, 10.8% resumed their use at 3 months. Of those discharged with BZD tapering, 74.1% were still on them 3 months later.

CONCLUSIONS

The majority of patients employing BZD lacked a medical indication. Admission to a geriatric ward resulted in successful discontinuation or dose reduction for most patients but was not maintained in the outpatient setting.
