Predicting opioid use disorder in patients with chronic pain who present to the emergency department.

Background: Emergency department (ED) patients with chronic pain challenge providers to make quick and accurate assessments without an in-depth pain management consultation. Emergency physicians need reliable means to determine which patients may receive opioid therapy without exacerbating opioid use disorder (OUD).

Methods: Eighty-nine ED patients with a chief complaint of chronic pain were enrolled.
