Mental Health Treatment Utilization Among Patients Receiving Collaborative Care for Co-occurring Disorders.
The authors aimed to examine the relationship between characteristics of patients and health systems and receipt of mental health treatment among patients assigned to collaborative care (CC) for opioid use disorder co-occurring with depression, posttraumatic stress disorder (PTSD), or both.
This secondary analysis used data from the intervention arm (N=400 participants) of a randomized clinical trial of CC, implemented in 18 low-resourced clinics, for patients with opioid use disorder co-occurring with depression, PTSD, or both. Outcomes were receipt of psychiatric medication or counseling during the 6-month intervention, as obtained from the electronic health records data or a caseload tracking tool. Baseline characteristics were assessed by using t tests for continuous variables and chi-square tests for categorical and binary measures. Adjusted logistic regression was used to identify associations between treatment receipt and characteristics; predicted probabilities for covariates were used to demonstrate effect size.
Of the patients, 51% received psychiatric medication and 44% received counseling. In the adjusted models, co-use of stimulants was associated with less likelihood of receiving psychiatric medication (adjusted odds ratio [AOR]=0.95) or counseling (AOR=0.92), as was lower education. Male sex and health system characteristics were associated with a lower likelihood of receiving counseling; non-Hispanic ethnicity and more severe depression and PTSD symptoms were associated with a greater likelihood of receiving counseling.
Even within CC settings, substantial unmet need for mental health treatment remained, particularly among individuals co-using stimulants. Future research should examine additional support to increase mental health treatment among individuals with co-occurring disorders.
