Return Rates for Opioid versus Nonopioid Management of Patients with Abdominal Pain in the Emergency Department.

BACKGROUND

Research suggests that opioid treatment for abdominal pain, which comprises a large proportion of patients presenting to the emergency department (ED), may contribute to long-term opioid use without significant benefits with regard to symptom management.

OBJECTIVES

This study seeks to assess the association between opioid use for management of abdominal pain in the ED and return ED visits for abdominal pain within 30 days for patients discharged from the ED at initial presentation.

METHODS

We conducted a retrospective, multicenter observational study of adult patients presenting to and discharged from 21 EDs with a chief concern of abdominal pain between November 2018 and April 2020. The proportion of 30-day return visits to the ED for patients who received opioid analgesics was compared with a reference group of patients who only received acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), or both.

RESULTS

Of the 4745 patients, 1304 (27.5%) received opioids and 1101 (23.2%) only received either acetaminophen, NSAIDs, or both. Among those given opioids, 287 (22.0%) returned to the ED for abdominal pain within 30 days, compared with 162 (14.7%) of those in the reference group (odds ratio 1.57, 95% confidence interval 1.27-1.95, p-value < 0.001).

CONCLUSION

Patients given opioids for abdominal pain in the ED had 57% increased odds of a return ED visit within 30 days compared with those given only acetaminophen or NSAIDs. This warrants further research on the use of nonopioid analgesics in the ED, especially in patients with anticipated discharge.
