Expert panel consensus on management of advanced cancer-related pain in individuals with opioid use disorder.

Question: What is the consensus of experts in palliative care, addiction, or both on the appropriateness of strategies to manage advanced cancer–related pain in individuals with co-occurring opioid use disorder? Findings: In this qualitative study, experts deemed it appropriate to continue medication for opioid use disorder (buprenorphine-naloxone or methadone) and to dose methadone outside the context of a methadone clinic 3 times per day. The appropriateness of adding full agonist opioids to either buprenorphine-naloxone or methadone depended on prognosis. Meaning: This study provides urgently needed, consensus-based guidance for clinicians and highlights critical research and policy gaps needed to facilitate implementation
