Benzodiazepine Utilization in Ischemic Stroke Survivors: Analyzing Initial Excess Supply and Longitudinal Trends

BACKGROUND

Benzodiazepines are commonly prescribed for post-acute ischemic stroke for anxiety, insomnia, and agitation. While guidelines discourage use in those aged ≥65 years, little is known about prescription patterns at the national level.

METHODS

We analyzed a 20% sample of US Medicare claims from April 1, 2013, to September 30, 2021. We selected beneficiaries aged ≥65 years discharged alive following an acute ischemic stroke who had traditional Medicare coverage and 6 months' prior enrollment in Parts A (hospital insurance), B (Medical insurance), and D (drug coverage). We excluded those with prior benzodiazepine prescriptions, self-discharges, or discharge to skilled nursing facilities. We examined demographics, comorbidities, first prescription days' supply, cumulative incidences of benzodiazepine first prescription fills within 90 days after discharge, and geographic and yearly trends.

RESULTS

We included 126 050 beneficiaries with a mean age of 78 years (SD, 8); 54% were female and 82% were White. Within 90 days, 6127 (4.9%) initiated a benzodiazepine. Among new prescriptions, lorazepam (40%) and alprazolam (33%) were the most prescribed. Most (76%) of first fills had a day's supply over 7 days and 55% between 15 and 30 days. Female initiation rates were higher (5.5% [95% CI, 5.3-5.7]) than male initiation rates (3.8% [95% CI, 3.6%-3.9%]). Rates were highest in the southeast (5.1% [95% CI, 4.8%-5.3%]) and lowest in the midwest (4.0% [95% CI, 3.8%-4.3%]), with a modest nationwide initiation decline from 2013 to 2021 (cumulative incidence difference, 1.6%).

CONCLUSIONS

Despite a gradual decline in benzodiazepine initiation from 2013 to 2021, we noted excessive supplies in prescriptions post-acute ischemic stroke discharge, underscoring the need for improved policies.

Disparities in the real-world prescription pattern of oral anticoagulants for US Medicare beneficiaries: a geospatial analysis

OBJECTIVES

This study was conducted to examine urban-rural differences in the real-world prescribing pattern of oral anticoagulants and geographic variations in the prescribing pattern among clinicians serving Medicare beneficiaries in the USA.

DESIGN

A cross-sectional study.

SETTING

A real-world setting.

PARTICIPANTS

232 665 clinicians who prescribed oral anticoagulants for Medicare beneficiaries from the 2020 Medicare Provider Utilisation and Payment Data were classified as warfarin only, direct oral anticoagulants (DOACs) only or warfarin+DOAC prescribers.

MAIN OUTCOME MEASURES

Urban-rural differences in the prescribing patterns were examined using multivariate multinominal logistic regression analysis. A geospatial analysis was conducted to estimate standardised prescriber ratios (SPR) for DOAC only or warfarin only prescribers versus warfarin+DOAC prescribers to illustrate hot and cold spots for DOAC adoption in the USA.

RESULTS

92% of clinicians who prescribed oral anticoagulants prescribed DOAC in 2020. Clinicians from rural regions were more likely to prescribe warfarin only (adjusted OR=1.335, 95% CI=(1.281 to 1.391)) and DOAC only (adjusted OR=2.052, 95% CI=(1.999 to 2.106)), compared with clinicians from urban regions. Hot spots for SPR of DOAC only versus warfarin+DOAC prescribers were mostly found in California, southern and southeastern states; cold spots were mostly found in Minnesota and Iowa. Hot spots for SPR of warfarin only versus warfarin+DOAC prescribers were mostly found in several metropolitan areas on the west coast and in Midwest; cold spots were mostly found on the east coast.

CONCLUSIONS

Urban-rural status of clinicians was associated with their prescribing patterns of oral anticoagulants. The study identifies geographical heterogeneity in DOAC adoption and highlights gaps that may need to be addressed for increased accessibility of DOAC for patients in need.

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.

Magnitude and Determinants of Long-term Use of Proton Pump Inhibitors Among Portuguese Older Adults in Primary Health Care

PURPOSE

Proton Pump Inhibitors (PPIs) have been associated with several adverse effects of particular concern in older populations. Their use for a period longer than 8 weeks is not recommended for older adults. Strategies to discontinue PPIs have been offered; however, their use remains high. This study aims to characterize PPI use in Portuguese older people and to identify the factors associated with potentially inappropriate use.

METHODS

A cross-sectional study was conducted on 1200 randomly selected older adults (≥65 years of age), users of primary health care facilities in the Regional Health Administration (Administração Regional de Saúde of Centro [ARSC]) of Portugal between April 2021 and August 2022. Data concerning their characteristics and PPI use were provided by the Shared Services of the Health Ministry (Serviços Partilhados do Ministério da Saúde) and collected retrospectively. Associations between independent variables and PPI use were investigated by logistic regression analysis.

FINDINGS

Of the older adults, 37.92% were receiving PPIs and 78.68% of them were taking them for a longer period than recommended; 49.79% were taking PPIs without having any digestive system-related disease. Multivariate analysis showed that the prolonged use of PPIs was not associated with any specific pattern, although inappropriate PPI use is high among Portuguese older adults.

IMPLICATIONS

Long-term PPI use in older adults is widespread and does not fit any particular patient profile; therefore, cross-cutting educational interventions should be designed independently of the patient's pathologic condition or treatment.

Considerations for long-acting antiretroviral therapy in older persons with HIV

People with HIV (PWH) can now enjoy longer, healthier lives due to safe and highly effective antiretroviral therapy (ART), and improved care and prevention strategies. New drug formulations such as long-acting injectables (LAI) may overcome some limitations and issues with oral antiretroviral therapy and strengthen medication adherence. However, challenges and questions remain regarding their use in aging populations. Here, we review unique considerations for LAI-ART for the treatment of HIV in older PWH, including benefits, risks, pharmacological considerations, implementation challenges, knowledge gaps, and identify factors that may facilitate uptake of LA-ART in this population.

Treating and Managing Laryngopharyngeal Reflux Disease in the Over 65s: Evidence to Date

PURPOSE

The clinical presentation and therapeutic outcomes of elderly patients may be different from those in younger populations, leading to additional diagnostic and therapeutic difficulties. The present study reviewed the findings on the epidemiology, and clinical, diagnostic, and therapeutic outcomes of elderly patients with laryngopharyngeal reflux (LPR).

METHODS

A PubMed, Cochrane Library, and Scopus literature search was conducted on the epidemiological, clinical, diagnostic, and therapeutic findings of elderly LPR patients.

FINDINGS

The prevalence of LPR in the elderly population remains unknown. From a clinical standpoint, older LPR patients report overall lower symptom scores and related quality-of-life outcomes at the time of the diagnosis. The required treatment time to obtain symptom relief appears to be longer in older compared with younger patients. Particular attention needs to be paid to prolonged medication use because the elderly population is characterized by polypharmacy and there is a higher risk of proton-pump inhibitor (PPI) interactions and adverse events. The plasma clearance of most PPIs is reduced with age, which must be considered by practitioners in the prescription of antireflux therapy.

CONCLUSION

The clinical presentation and treatment efficacy of elderly LPR patients differ from those in younger patients. Practitioners need to carefully consider the risk of drug interactions and adverse events in elderly patients.
