Conversion of CII Opioid Medications to Buprenorphine in the Chronic Pain Population - Insights and Clinical Pearls.

Abstract

There is a great deal of confusion associated with conversion from CII opioid to buprenorphine products. The data presented supports that patients can be converted from high dose opioid medication to buprenorphine products safely and effectively. This presentation will provide a road map to help guide practitioners who are interested in applying this to their clinical practice. Thepurposeoftheresearchwasnotonlytodiscoverifconversiontoapartialagonist CIII medication from full agonist CII medications would be achieveable without sacrificing analgesia, but also to provide guidance to providerswhoareinterestedinpursuingthisoptioninclinicalpractice. Procedures/data/observations: Patients who met inclusion criteria were stratified into subgroups on the basis of pre- conversion morphine milligram equivalents, whether they remained on opioids for breakthrough pain postconversion, and pre- and postconversion numerical rating scale pain scores. Outcomes of interest included the differences between pre- and postconversion numerical rating scale pain scores and daily morphine milligram equivalents for each sub-group. Of 157 patients reviewed, 87.9% were successfully converted to buprenor-phine buccal film. Overall, numericalrating scale pain scores were stable after conversion. Statistically significant reductions were demonstrated in the <90 daily morphine milligram equivalent subgroup. Postconversion daily morphine milligram equivalents decreased by 85.4% from baseline. Change in daily morphine milligram equivalents is representative of patients who remained on breakthrough pain medication. Results demonstrate continued analgesia after conversion to buprenorphine buccal film despite reductions in daily morphine milligram equivalents. Most patients were able to convert directly from their long-acting opioid to buprenorphine buccal film and stabilized without the use of concomitant opioids for breakthrough pain. Aggressive titration strategies were associated with greater success. This data proves that conversion from full agonist CII medications is possible without sacrificing analgesia while reducing the risk of adverse events associated with full agonist CII medications.
