In the Original Investigation “Incidence of and Risk Factors for Chronic Opioid Use Among Opioid-Naive Patients in the Postoperative Period,”1 published in September 2016 in JAMA Internal Medicine, the disclosure statement for Dr Darnall should have read as follows: “Dr Darnall reported serving as a consultant for Axial Health regarding the development of physician education materials on opioid prescribing and safety, receiving shares from the company, and that payments for consulting services were paid to Stanford University; serving on the advisory board for Clinical Pain Advisor, an online pain media outlet, and that compensation for her services was paid to Stanford University; receiving royalties from 2 books on patient self-help for opioid reduction and pain management for chronic pain; and receiving from Tarsus and Neurovations travel reimbursements to present pain research findings at the PainWeek conference and the Kauai Pain Conference, respectively.” This article has been corrected online.
