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.
