Decision Support and Behavioral Health for Reducing High-Dose Opioids in Comorbid Chronic Pain, Depression and Anxiety: Stepped-Wedge Cluster Randomized Trial.

Background: High prevalence of depression or anxiety with opioid use for chronic pain complicates co-management and may influence prescribing behaviors.

Objective: Compare clinical effectiveness of electronic medical record clinical decision support (EMR-CDS) versus additional behavioral health (BH) care management for reducing rates of high-dose opioid prescriptions.

Design: Type 2 effectiveness-implementation hybrid stepped-wedge cluster randomized trial in 35 primary care clinics within a health system in LA, USA.

Participants: Patients aged 18+ receiving chronic opioid therapy for non-cancer pain with depression or anxiety and matched controls.

Intervention: EMR-CDS included opioid risk mitigation procedures. BH care included cognitive behavioral therapy; depression or anxiety medication adjustments; and case management.

Main Measures: Outcomes of interest included difference-in-difference (DID) estimate of changes in probability for prescribing high-dose morphine equivalent daily dose (MEDD ≥50 mg/day and MEDD ≥90), average MEDD, and rates of hospitalization, emergency department use, and opioid risk mitigation.

Key Results: Most participants were female with 3+ pain syndromes. Data analysis included 632 patients. Absolute risk differences for MEDD≥50 and ≥90 decreased post-index compared to pre-index (DID of absolute risk difference [95%CI]: -0.036 [-0.089, 0.016] and -0.029 [-0.060, 0.002], respectively). However, these differences were not statistically significant. The average MEDD decreased at a higher rate for the BH group compared to EMR-CDS only (DID rate ratio [95%CI]: 0.85 [0.77, 0.93]). There were no changes in hospitalization and emergency department utilization. The BH group had higher probabilities of new specialty referrals and prescriptions for naloxone and antidepressants.

Conclusions: Incorporation of a multidisciplinary behavioral health care team into primary care did not decrease high-dose prescribing; however, it improved adherence to clinical guideline recommendations for managing chronic opioid therapy for non-cancer pain.
