What this trial studies

This clinical trial aims to compare the effectiveness of two medications, duloxetine and desipramine, in treating chronic pain in patients. It utilizes a pragmatic approach by integrating randomized comparative effectiveness research directly into patient care through the Collaborative Health Outcomes Information Registry (CHOIR). Patients will be randomized to receive either medication, and their progress will be monitored using advanced patient-reported outcomes metrics. This study addresses the gap in treatment options for patients with chronic pain, particularly those with complex medical histories.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have experienced persistent pain for more than three months and are candidates for treatment with antidepressants.

Not a fit: Patients who have previously failed treatment with duloxetine or desipramine, or those with contraindications to these medications, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide more effective treatment options for patients suffering from chronic pain.

How similar studies have performed: Other studies have shown promise in comparing different antidepressants for chronic pain, but this specific approach using point of care randomization is relatively novel.
