Adapting low-dose buprenorphine induction to meet patient needs: A pilot study

Abstract

Introduction: Low-dose buprenorphine induction (LDBI) has been proposed to initiate buprenorphine in patients who are taking full opioid agonists in order to limit the risk of precipitated withdrawal. The objective of this study was to understand how real-world patient-specific adjustments in LDBI protocols impacted success rates in buprenorphine conversion. Methods: This case series identified patients seen by the Addiction Medicine Consult Service at UPMC Presbyterian Hospital who were started on LDBI with transdermal buprenorphine followed by sublingual buprenorphine-naloxone between April 20, 2021, and July 20, 2021. The primary outcome was successful induction of sublingual buprenorphine. Characteristics of interest included total morphine milligram equivalents (MME) in the 24 hours prior to induction, MME during each day of induction, total time of induction, and final daily maintenance buprenorphine dose. Results: Of the 21 patients included for analysis, 19 (91%) successfully completed LDBI and converted to a maintenance buprenorphine dose. Median (IQR) opioid analgesia utilization in the 24 hours prior to induction was 113 MME (63–166 MME) in the converted group and 83 MME (75–92 MME) in the group that did not convert. Conclusions: Transdermal buprenorphine patch followed by sublingual buprenorphine-naloxone resulted in a high success rate for LDBI. Patient-specific adjustments may be considered in order to effect a high success rate of conversion.
