It is important to understand the unintended consequences of this approach to inform treatment decisions and the consideration of alternative treatments. Recent evidence has shown that ED opioid prescriptions are associated with future opioid use. The objective of this study was to measure the association of opioid administration in the ED to patients treated for back pain with future opioid use.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is a retrospective study of opioid\u2010na\u00efve adults discharged from the ED with a diagnosis of back pain. Patients were stratified by opioid therapy (none, ED administration only, prescription only, or ED administration\u00a0+\u00a0prescription). Relative risks of ongoing opioid use (filling &gt;90\u2010day supply in 180\u00a0days following ED visit as documented in the prescription drug monitoring program) were calculated for each opioid\u2010therapy group and compared to the no\u2010opioid group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified 24,487 opioid na\u00efve back pain patients. The median age was 38\u00a0years, 55% were female, and 56% were non\u2010Hispanic white. A total of 41% received no opioid, 10% were only administered an opioid in the ED, 18% only received a prescription, and 31% received an opioid in the ED\u00a0+\u00a0prescription. The adjusted relative risks of ongoing use compared to the no opioid group were as follows: ED only 1.9, prescription only 2.1, and ED\u00a0+\u00a0prescription 2.3. The increased risk persisted for other definitions of ongoing use and after adjustment for baseline pain scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>For opioid\u2010na\u00efve patients with back pain, both administration of an opioid in the ED and opioid prescriptions are associated with a doubling of the risk of ongoing opioid use compared to patients not treated with opioids. This supports the consideration of minimizing exposure to opioids while treating back pain in the
