National Variation in Opioid Prescribing and Risk of Prolonged Use for Opioid-Naive Patients Treated in the Emergency Department for Ankle Sprains

Between 2011 and 2015, nearly one in four patients with ankle sprains were prescribed opioids in the emergency department. The overall prescribing rate declined during the study period, but varied significantly by state, ranging from 2.8% in North Dakota to 40% in Arkansas. Patients prescribed the largest amounts of opioid were nearly five times more likely to transition to continued use as those prescribed lesser amounts.
