Benzodiazepine Initiation Effect on Mortality Among Medicare Beneficiaries Post‐Acute Ischemic Stroke
This study looked at how starting to take benzodiazepines (BZDs) affects survival in older adults after a stroke. BZDs are medications typically used for anxiety, insomnia, and seizures. The study focused on patients 66 years old and older on Medicare and determined whether taking BZDs within 30 days after leaving the hospital increased their risk of dying within 90 days. The study analyzed over 47,000 patients, selecting those with more favorable outcomes, and found that 1.74% began taking BZDs after their stroke. After adjusting for factors like age, gender, race, hospital stay, and dementia, we found that starting BZDs was associated with a higher risk of death. The risk was particularly high in patients 86 years and older and those with dementia. The study concluded that prescribing BZDs to older stroke survivors could substantially raise the risk of death, especially in the oldest and most vulnerable patients.
