OBJECTIVES: To compare the effectiveness of 3 approaches for communicating opioid risk during an emergency department visit for a common painful condition. METHODS: This parallel, multicenter randomized controlled trial was conducted at 6 geographically disparate emergency department sites in the United States. Participants included adult patients between 18 and 70 years of age presenting with kidney stone or musculoskeletal back pain. Participants were randomly assigned to 1 of 3 risk communication strategies: (1) a personalized probabilistic risk visual aid, (2) a visual aid and a video narrative, or (3) general risk information. The primary outcomes were accuracy of risk recall, reported opioid use, and treatment preference at time of discharge. RESULTS: A total of 1,301 participants were enrolled between June 2017 and August 2019. There was no difference in risk recall at 14 days between the narrative and probabilistic groups (43.7% versus 38.8%; absolute risk reduction 4.9%; 95% confidence interval (CI) -2.98 to 12.75). The narrative group had lower rates of preference for opioids at discharge than the general risk information group (25.9% versus 33.0%; difference 7.1%; 95% CI 0.64 to 0.97). There were no differences in reported opioid use at 14 days between the narrative, probabilistic, and general risk groups (10.5%, 10.3%, and 13.3%, respectively; p = 0.44). CONCLUSIONS: An emergency medicine communication tool incorporating probabilistic risk and patient narratives was more effective than general information in mitigating preferences for opioids in the treatment of pain but was not more effective with respect to opioid use or risk recall.
