Acute Pain Management for Patients with Substance Use Disorder Receiving Buprenorphine or Methadone Compared to Patients without Opioid-Dependence Disorder.

This single-center retrospective study assessed pain management between patients being treated for SUD and compared them to those without SUD who underwent orthopedic surgery. Patients with SUD could be admitted for any reason, while the control arm consisted of patients undergoing total knee arthroplasty or hip arthroplasty surgery. Primary endpoints were average pains scores and morphine milligram equivalents (MME) over the first 48h.
