Key Takeaway
Stimulant co-use and lower education levels are significant barriers to accessing mental health treatment in OUD care.

This secondary analysis of a randomized clinical trial evaluated a collaborative care (CC) model across 18 low-resourced clinics. The study focused on patients with opioid use disorder (OUD) who also presented with depression, PTSD, or both. The primary objective was to measure the receipt of psychiatric medication and counseling over a six-month period.

Results showed that 51% of the 400 participants received psychiatric medication, while 44% received counseling. However, specific patient characteristics significantly influenced these outcomes. Notably, patients who co-used stimulants were less likely to receive either psychiatric medication or counseling compared to those who did not.

Additional barriers included lower education levels, which correlated with reduced access to treatment. Demographic factors also played a role; for instance, male patients were less likely to receive counseling, while non-Hispanic patients showed higher rates of counseling. Conversely, patients with more severe depression and PTSD symptoms were more likely to receive counseling, highlighting the impact of symptom severity on treatment engagement.

How this fits prior evidence

How this fits prior evidence: This finding addresses a gap in understanding treatment barriers for patients with opioid use disorder and co-occurring mental health conditions. While prior coverage noted that PTSD, major depressive disorder, and borderline personality disorder are highly prevalent in patients with Dissociative Identity Disorder, this study specifically examines the delivery of care for those with opioid use disorder and co-occurring depression or PTSD. It highlights how specific factors like stimulant co-use and education levels impact the likelihood of receiving psychiatric medication or counseling.

A study looked at 400 people who had opioid use disorder along with mental health issues like depression or PTSD. The goal was to see how many patients received medication or counseling during a six-month period of collaborative care.

Results showed that about half of the patients received psychiatric medication, while about 44% received counseling. However, some people faced more hurdles. For example, patients who also used stimulants were less likely to get medication or counseling. People with lower levels of education also faced a harder time getting these services.

Other factors influenced care. Men were less likely to receive counseling, while people of non-Hispanic ethnicity were more likely to get it. Patients with more severe symptoms of depression and PTSD were more likely to receive counseling. These findings help doctors see who might need extra support to get the care they need.

What this means for you:
Patients using stimulants or with less education face more barriers to getting mental health treatment.

Common questions

What were the main findings regarding treatment access?

In a study of 400 patients with opioid use disorder, 51% received psychiatric medication and 44% received counseling over six months. The study highlighted that certain factors, such as lower education levels or the co-use of stimulants, were associated with a lower likelihood of receiving these essential mental health services.

How did other factors like sex or symptoms affect care?

The study found that men were less likely to receive counseling. In contrast, patients with more severe depression and PTSD symptoms were more likely to receive counseling. Non-Hispanic patients were also found to have a greater likelihood of receiving counseling during the study period.

What role did stimulant use play in the results?

The data showed that the co-use of stimulants was associated with a lower likelihood of receiving both psychiatric medication and counseling. These findings suggest that certain patient profiles may face more barriers to accessing care in collaborative settings.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
