Benzodiazepine Overprescribing Remains a Problem Post-Stroke

TOPLINE:


About 5% of people older than 65 years in the United States are prescribed benzodiazepine after acute ischemic stroke (AIS) despite warnings of potential side effects in older adults, a new study shows. Although the findings indicate a slight decrease in benzodiazepine use for post-stroke anxiety (PSA) over the past decade, investigators say overdiagnosis remains a problem.


Benzodiazepine

METHODOLOGY:


  • Researchers analyzed a sample of US Medicare claims from April 2013 to September 2021.

  • A total of 126,050 beneficiaries (mean age, 78 years; 54% women; 82% White) discharged alive following an AIS were included.

  • Patients previously prescribed benzodiazepine and those with self-discharge or discharge to skilled nursing facilities were excluded.

  • Researchers assessed the demographics and comorbidities of patients, initial prescription lengths, cumulative incidence of first fills of benzodiazepine within 90 days post-discharge, and geographic and yearly trends.


TAKEAWAY:


  • Within 90 days of discharge, 5% of stroke survivors were initiated on benzodiazepine, with lorazepam (40%) and alprazolam (33%) prescribed most often.

  • Most (76%) of first-time benzodiazepine prescriptions had a supply of > 7 days, with 55% covering 15-30 days.

  • Women had higher initiation rates than men (6% vs 4%), and Hispanic adults had a higher cumulative incidence (6%) than adults of other ethnicities.

  • Prescription rates were the highest in the Southeast (5%) and lowest in the Midwest (4%), with a slight countrywide decline (cumulative incidence difference, 1.6%) during the study period.


IN PRACTICE:


“Despite declining trends in benzodiazepine prescriptions, it is necessary to note that use remains alarming in the United States as it represents the third most used illicit or prescription drug in the country,” the authors wrote.


Authors of an accompanying editorial noted that ideally, patients with stroke would be screened for PSA at discharge to allow for early diagnosis and appropriate treatment. “Unfortunately, access to mental health services after stroke can be limited, and not all hospitals or clinics will have these types of resources available,” the authors wrote. “These limitations require stroke physicians to often become the first line of treatment for PSA and sometimes are the only option available.”
