These findings amplify the safety signal from previous inpatient studies by showing that even a short course of opioids in an outpatient setting may increase risks of corticosteroid use and emergency department utilization, prompting caution among prescribers, reported Laura Telfer, MS, of Penn State College of Medicine, Hershey, Pa., and colleagues.
“Opioids are frequently prescribed to treat pain associated with IBD,” the investigators wrote in Gastro Hep Advances. “Unfortunately, they are associated with many problems in IBD, including increased risk of emergency room visits, hospitalization, surgery, and mortality. Chronic opioid use may also exacerbate symptoms and induce IBD flares, prompting discontinuation, thus increasing the risk of opioid withdrawal syndrome. Ironically, there is no published evidence that opioids even help to improve abdominal pain in IBD, particularly in the long term. Notably, most studies investigating opioid use in IBD have been limited to hospitalized patients, and few have directly evaluated the impact of opioid prescription length.”

To address this knowledge gap, Ms. Telfer and colleagues conducted a retrospective, population-based cohort study involving patients with IBD who were classified as either long-term opioid users, short-term opioid users, or nonusers. Drawing data from more than 80,000 patients in the TriNetX Diamond Network, the investigators evaluated relative, intergroup risks for corticosteroid use, emergency department utilization, mortality, and IBD-related surgery.
Comparing short-term opioid users and nonusers revealed that short-term use more than doubled the risk of corticosteroid prescription (relative risk [RR], 2.517; P less than .001), and increased the risk of an emergency department visit by approximately 32% (RR, 1.315; P less than .001). Long-term use was associated with a similar doubling in risk of corticosteroid prescription (RR, 2.383; P less than .001), and an even greater risk of emergency department utilization (RR, 2.083; P less than .001). Risks of death or IBD-related surgery did not differ for either of these comparisons.
Next, the investigators compared long-term opioid use versus short-term opioid use. This suggested a duration-related effect, as long-term users were 57% more likely than were short-term users to utilize emergency department services (RR, 1.572; P less than .001). No significant differences for the other outcomes were detected in this comparison.
“Unlike previous studies, we did not find an association between opioid use and IBD-related surgery or death,” the investigators wrote. “Notably, these [previously reported] associations utilized opioid dosage (e.g., morphine equivalent or number of prescriptions), rather than length of opioid prescription (as we did). We also focused on IBD outpatients, while prior studies evaluated (in part or completely) inpatient populations, who typically present with more severe illness.”
Still, they added, the present findings should serve as a warning to prescribers considering even a short course of opioids for patients with IBD.
“This study demonstrates that prescribing opioids to IBD outpatients carries significant, specific risks, regardless of prescription length,” Ms. Telfer and colleagues wrote. “Healthcare professionals should exercise caution before prescribing these agents.”
The study was supported by the Peter and Marshia Carlino Early Career Professorship in Inflammatory Bowel Disease, the Margot E. Walrath Career Development Professorship in Gastroenterology, and the National Institutes of Health. The investigators disclosed no conflicts of interest.
