Patterns of benzodiazepine administration and prescribing to older adults in U.S. emergency departments.

Despite the documented risks associated with the utilization of benzodiazepines in older adults, the rate of use in EDs continues to increase. Older adults administered benzodiazepines in the ED were more likely to be admitted to the hospital than those not receiving these agents. Despite the risks associated with co-prescription of benzodiazepines with opioids, those receiving these agents were no less likely to be administered opioids than those who did not. Older adults administered benzodiazepines in the ED were substantially more likely to be diagnosed with delirium in the ED.
