Transdermal Initiation of Buprenorphine Among Hospitalized Persons: A Retrospective Study.

BACKGROUND

Buprenorphine is an effective treatment for opioid use disorder but may be difficult to initiate among hospitalized patients due to concerns about acute pain and withdrawal risks.

OBJECTIVE

We sought to evaluate the safety and effectiveness of a novel approach for initiating buprenorphine treatment that did not require patients to first discontinue full-agonist opioids or experience an acute opioid withdrawal syndrome. This approach, referred to as low-dose initiation with opioid continuation (LDI), involved applying a transdermal patch which delivered microgram-level doses of buprenorphine for 24 h or longer, allowing for a gradual cross-titration of patients from full-agonist opioids to sublingual buprenorphine during their hospital stay.

METHODS

Individuals who attempted LDI between April 2021 and July 2022 at a large urban academic hospital and an affiliated community hospital were included in the analysis. A LDI was deemed successful for patients receiving nontransdermal buprenorphine at the date of their discharge. Precipitated opioid withdrawal was defined as a relative score increase of 5 or more from pretreatment baseline on the Clinical Opiate Withdrawal Scale assessment, as long as the score exceeded 8 and occurred within 48 h of the patient receiving buprenorphine as part of the LDI. Descriptive statistics were performed comparing the characteristics of persons who did complete the LDI protocol to those who did not, and those who did experience precipitated opioid withdrawal to those who did not.

RESULTS

A total of 67 patients were assessed. 79.1% completed the LDI successfully. Precipitated withdrawal occurred in 16.4% of patients. Morphine-milligram equivalents of opioids administered pre-LDI did not predict LDI completion. Surprisingly, persons who experienced precipitated withdrawal were more likely to complete LDI. Persons who completed the LDI were more likely to attend an outpatient or bridge clinic follow-up visit within 30 days of discharge.

CONCLUSIONS

LDI with transdermal buprenorphine was found to be generally safe and well-tolerated in these hospitalized patients. Compared to other published studies of LDI, rates of successful initiation of buprenorphine were largely equivalent. Further research is needed on predictors of unsuccessful and successful LDI.
