AbstractBuprenorphine has demonstrated benefit for acute and chronic pain and various psychiatric disorders. However, many studies evaluating buprenorphine's effect on psychiatric conditions are not specific to the chronic pain population. This retrospective study was conducted to assess the impact of buprenorphine on depressive symptoms in patients with chronic pain at a Veterans Affairs healthcare facility. Adults with chronic pain started on any formulation of buprenorphine or traditional opioid (non-buprenorphine opioid) with at least two depression screenings between May 1, 2016 and November 1, 2021 were included. The primary outcome was change in depressive symptoms, measured by Patient Health Questionnaire-9 (PHQ-9), from baseline to 6-18 months after starting therapy. Secondary outcomes included changes in Columbia-Suicide Severity Rating Scale and mental health services utilization. Twenty-one patients were included. Median baseline PHQ-9 in the buprenorphine and traditional opioid groups were 14 and 13, respectively. Median change in PHQ-9 was -5 in the buprenorphine group and -1.5 in the traditional opioid group. Compared to traditional opioids, buprenorphine was associated with a greater reduction in depressive symptoms among Veterans with chronic pain. Although this reduction met the threshold for clinically significant improvement, further investigation is needed to evaluate the clinical relevance of these findings.
