Based on 2013-2014 nationally representative surveillance data, the study found the prevalence of emergency department visits for adverse drug events in the United States was estimated to be 4 per 1000 individuals. The most common drug classes implicated were anticoagulants, antibiotics, diabetes agents, and opioid analgesics.
