Collaborative Care for Depression and Anxiety: Racial-Ethnic Differences in Treatment Engagement and Outcomes.

OBJECTIVE: This study aimed to examine racial-ethnic differences in engagement with and clinical outcomes of a collaborative care model (CoCM) implemented in primary care outpatient clinics in an urban academic medical center. METHODS: Adult patients (N=4,911) who screened positive for symptoms of depression, anxiety, or both on the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 scale and who identified as non-Hispanic Black, Hispanic, or non-Hispanic White were offered participation in a CoCM implementation. The primary outcome was treatment engagement, defined as receipt of any follow-up visit, minimally adequate 4-week follow-up (at least one visit), and minimally adequate 16-week follow-up (at least three visits) after initial assessment. Secondary outcomes were response and remission of depression or anxiety. RESULTS: After adjustment of analyses for sociodemographic covariates, Black and Hispanic participants were significantly less likely than White participants to have received any or minimally adequate follow-up. Black and Hispanic participants who received any or minimally adequate 16-week follow-up were more likely than White participants to demonstrate depression symptom response and remission of anxiety symptoms. CONCLUSIONS: This CoCM implementation appears to have been effective in treating depression and anxiety among Black and Hispanic patients. However, significant disparities in receipt of follow-up care were observed. Efforts must be made to improve the retention of patients from racial-ethnic minority groups in collaborative care.

Racial and Ethnic Disparities in Childhood ADHD Treatment Access and Utilization: Results From a National Study.

OBJECTIVE: The study examined racial-ethnic disparities in access to and utilization of treatment for attention-deficit hyperactivity disorder (ADHD) and other psychiatric diagnoses among children with ADHD. METHODS: Nationally representative, cross-sectional data from the Household Component of the Medical Expenditure Panel Survey 2011-2019 were used to examine racial-ethnic disparities in access to and utilization of treatment by children ages 5-17 with ADHD (N=5,838). Logistic regression models were estimated for access outcomes, and generalized linear models were estimated for utilization outcomes. Multivariable regression models adjusted for race-ethnicity, age, sex, and treatment need in accordance with the Institute of Medicine definition of health care disparities. RESULTS: In adjusted analyses, compared with White children with ADHD, Black, Hispanic, and Asian children with ADHD had significantly lower rates of any past-year treatment visit for ADHD or for other psychiatric diagnoses. They also had lower rates of having accessed ADHD medication. Compared with White children, Black and Asian children with ADHD used fewer ADHD medications, and Black and Hispanic children with ADHD had lower overall mental health treatment expenditures. CONCLUSIONS: Disparities in ADHD treatment among children from racial-ethnic minority populations may be driven primarily by disparities in access rather than in utilization. Once treatment had been accessed, disparities in utilization were largely accounted for by differences in socioeconomic status. These findings suggest that interventions targeting access to treatment among children from racial-ethnic minority populations may help close existing care gaps.

Disparities in Mental Health Care Utilization and Perceived Need Among Asian Americans: 2012-2016.

OBJECTIVE: The objective was to examine mental health treatment access disparities between Asians and whites in the United States as well as the role of perceived and objective need and barriers to treatment in these disparities. METHODS: Data are five annual cross-sections (2012-2016) of responses from Asian Americans and whites to the nationally representative National Survey on Drug Use and Health. Multivariate logistic regression analyses adjusting for sociodemographic factors were conducted to compare past-year treatment access rates between Asians and whites across three need subgroups: those with perceived need for treatment, those with past-year serious psychological distress, and those with a past-year major depressive episode. Barriers to treatment were compared between Asians and whites with perceived need. RESULTS: Asians were less likely than whites to have accessed mental health treatment in the past year in all analyses. Compared with Asians with need determined by structured diagnostic instruments, Asians with perceived need had higher rates of mental health care access, but even among respondents with perceived need, the disparity between whites and Asians remained. Regarding barriers to treatment, only one barrier (not knowing where to go for treatment) was more likely to be reported for Asians than whites. CONCLUSIONS: Differences between Asians and whites in perceived need for mental health treatment do not explain the wide disparities in mental health care access between these two groups. Clinical interventions improving the relevance and fit of mental health care and community-based outreach interventions increasing awareness of available services are needed to improve access to mental health treatment among Asians.
