This secondary analysis of the CLARO randomized trial examined clinical complexity in 797 adults with opioid use disorder (OUD) and co-occurring depression and/or PTSD. The study identified three subgroups based on baseline clinical complexity and found that collaborative care (CC) led to lower depression severity compared to enhanced usual care (EUC) only in the low-complexity group, with no significant differences in PTSD outcomes or buprenorphine utilization.
Key findings
- Three subgroups identified: low complexity (43%), mental health complexity (34%), and high dual complexity (23%).
- CC was associated with lower depression severity at follow-up for the low-complexity class compared to EUC.
- No significant differences in PTSD outcomes between CC and EUC across any complexity class.
- Buprenorphine utilization and prescribing duration were similar between CC and EUC.
Why it matters
Understanding the impact of clinical complexity on treatment outcomes can help clinicians tailor interventions for patients with OUD, particularly in determining when collaborative care may be most effective.
