Background: National guidelines advise decreasing opioids for chronic pain, but there is no guidance on implementation.
Objective: To evaluate the effectiveness of an Integrated Pain Team (IPT) clinic in decreasing opioid dose and mitigating opioid risk.
Design: This study prospectively compared two matched cohorts receiving chronic pain care through IPT (N = 147) versus usual primary care (UPC, N = 147) over 6 months. Patients were matched on age, sex, psychiatric diagnoses, and baseline opioid dose.
Patients: Veterans receiving care at a VA medical center or VA community-based clinics.
Intervention: Interdisciplinary IPT, consisting of a collocated medical provider, psychologist, and pharmacist embedded in VA primary care providing short-term biopsychosocial management of veterans with chronic pain and problematic opioid use.
Main measures: Change in opioid dose expressed as morphine equivalent daily dose (MEDD) and opioid risk mitigation evaluated at baseline, 3 months, and 6 months.
Key results: Compared with veterans receiving UPC, those followed by IPT had a greater mean MEDD decrease of 42 mg versus 8 mg after 3 months and 56 mg versus 17 mg after 6 months. In adjusted analysis, compared with UPC, veterans in IPT achieved a 34-mg greater mean reduction at 3 months (p = 0.002) and 38-mg greater mean reduction at 6 months (p = 0.003). Nearly twice as many patients receiving care through IPT versus UPC reduced their daily opioid dose by ≥50%, representing more than a two-fold improvement at 3 months, which was sustained at 6 months [odds ratio = 2.03; 95% CI = 1.04-3.95, p = 0.04]. Significant improvements were also demonstrated in opioid risk mitigation by 6 months, including increased urine drug screen monitoring, naloxone kit distribution, and decreased co-prescription of opioids and benzodiazepines (all p values < 0.001).
Conclusions: Interdisciplinary biopsychosocial models of pain care can be embedded in primary care and lead to significant improvements in opioid dose and risk mitigation.
