Pain Management at End of Life with Substance Use History
Mr. R, a 58-year-old man with metastatic pancreatic cancer, is admitted to hospice with severe abdominal pain. He has a history of opioid use disorder (OUD) and has been on buprenorphine/naloxone for 2 years. He reports pain 8/10 despite taking oxycodone 5 mg every 6 hours as needed. The hospice team is concerned about prescribing higher doses of opioids due to his OUD history. Mr. R is anxious and feels his pain is not being believed. His family is supportive but worried about addiction.
1. What is the appropriate approach to pain management for Mr. R, considering his OUD history?
Read the worked answer
The hospice team should recognize that untreated pain is a trigger for relapse and that Mr. R has a right to adequate pain relief. Buprenorphine/naloxone may interfere with full opioid agonists; consult with an addiction specialist to consider transitioning to a full agonist or adjusting buprenorphine dose. Use a multimodal approach: optimize around-the-clock long-acting opioid (e.g., methadone or extended-release morphine) with short-acting for breakthrough, plus adjuvants (e.g., gabapentin, corticosteroids). Non-pharmacologic methods (relaxation, heat) can help. Establish clear goals and a contract for opioid use, involve family in education to reduce stigma, and monitor for signs of misuse. Document carefully.
2. How should the team address the family's concerns about addiction?
Read the worked answer
The team should provide education that physical dependence and addiction are different, and that in terminal illness, the priority is comfort. Explain that Mr. R's history means he may require higher doses due to tolerance, and that the team will monitor closely. Acknowledge the family's fears and provide reassurance that the team is experienced in managing pain in patients with OUD. Offer a meeting with the palliative care physician or addiction specialist to answer questions. Encourage the family to report any concerning behaviors without judgment. Emphasize that untreated pain can lead to relapse, so adequate treatment is part of recovery.
