Comparing Methadone Rotation to Consensus Opinion.

ABSTRACT

CONTEXT Methadone is a complex but useful medication for pain management in palliative care. Recent expert opinions have been published on the safe and effective use of methadone. OBJECTIVES: To determine the success of methadone rotations and evaluate concordance with consensus recommendations by a palliative care consult service. METHODS: A retrospective study of methadone rotation practice by a palliative care consult service and outcomes for patients hospitalized between January 1, 2012 and December 31, 2018 at a single academic medical center. A successful rotation was defined as a 30% reduction in pain or as-needed medication use sustained for at least three consecutive days. Patient outcomes were compared with expert consensus recommendations. RESULTS: About 59 patients met the inclusion criteria. The study population was mostly Caucasian men and women of equal proportions who were started on methadone for inadequate pain control. Sixty-eight percent of patients were successfully rotated. Subjects who were rotated using a standardized protocol were six times more likely to have a successful rotation (odds ratio 6.28 [1.25-30.92]; P = 0.0238). CONCLUSION: The utilization of a standardized protocol was associated with better patient outcomes.
