Acute pain management in hospitalized adult patients with opioid dependence: a narrative review and guide for clinicians

• Continue maintenance therapy with buprenorphine and treat acute pain with short acting opioid agonists. Higher doses of opioid agonists and more frequent dosing may be needed to provide adequate pain relief since they compete with buprenorphine at the mu receptor. Opioids with higher affinity for the mu receptor (morphine, hydromorphone, fentanyl) may be more efficacious.
• Discontinue buprenorphine and treat the patient with scheduled full opioid analgesics, titrating the dose initially to try to avoid withdrawal and then to provide pain relief. The partial agonism of the mu-receptor from buprenorphine and the blockade of other opioids can persist for as long as 72 hours. During this period, close monitoring and keeping naloxone available are important. When acute pain resolves, discontinue full opioid agonist therapy and resume buprenorphine using an induction protocol.

For our clinical example, we recommend continuing buprenorphine at 16 mg daily, optimizing nonopioid treatment strategies, and using a higher dose parenteral full opioid agonist every 3 hours as needed to achieve adequate analgesia. The patient should be frequently monitored for adverse effects, and naloxone kept available. Full opioid analgesics should be tapered and discontinued as the acute pain resolves. The patient should be reassured that there is no evidence that using opioids to treat acute pain episodes increases the risk of relapse and that untreated acute pain is a more likely trigger for relapse. The patient’s buprenorphine provider should be contacted at admission to verify dose as well as at discharge.

Early discharge planning is essential for appropriate and safe management of acute pain in hospitalized patients with opioid dependence. The major goals are to treat acute pain effectively, improve function, and return care to the patient’s usual treating physician or methadone clinic. Patients on chronic opioid therapy often have a written opioid treatment agreement specifying only 1 prescriber. Therefore, verbal communication with the patient’s authorized prescriber at admission and at discharge is essential, particularly given that the discharge summary may not be available at follow-up. Additional or higher doses of opioids should not be prescribed at discharge unless discussed with the patient’s authorized prescriber. If it is believed necessary to provide opioid medication at discharge it should only be provided for a short period: 3 to 7 days.³⁵ Patients with OUD should be referred for addiction treatment, including MAT, and should be educated on harm-reduction strategies, including safe injecting, obtaining clean needles, and recognizing, avoiding, and treating opioid overdose. Prescribing intranasal naloxone should be strongly considered for patients with OUD and for patients who are taking more than 50 mg oral morphine equivalents for chronic pain.³⁴

Management of acute pain in opioid-dependent patients is a complex and increasingly common problem encountered by hospitalists. In addition, given the OUD epidemic in the United States, safe opioid prescribing has become a paramount goal for all physicians. Although acute pain management will be individualized and will encompass clinical judgment, this review provides an evidence-based guide to effective and safe acute pain management and optimal opioid prescribing for hospitalized opioid-dependent patients.
