Objective
The objective of this study is to characterize racial/ethnic variation in mental health diagnoses and treatments in large not-for-profit healthcare systems.
Method
Participating systems were 11 private, not-for-profit healthcare organizations constituting the Mental Health Research Network (MHRN) and had a combined 7,523,956 patients aged 18 years or older, who received care during 2011. Rates of diagnoses, psychotropic medications, and formal psychotherapy sessions received were obtained from insurance claims and electronic medical record databases across all healthcare settings.
Results
Of the 7,523,956 patients in the study, 1,169,993 (15.6%) received a mental health diagnosis in 2011. This varied significantly by race/ethnicity with Native American/Alaskan Native patients having the highest rates of any diagnosis (20.6%) and Asians having the lowest rates (7.5%). Among patients with a mental health diagnosis, 73% (n = 850,585) received a psychotropic medication. Non-Hispanic white patients were significantly more likely (77.8%) than other racial/ethnic groups (range 61.5% to 74.0%) to receive medication. In contrast, only 34% of patients with a mental health diagnosis (n = 548,837) received formal psychotherapy. Racial/ethnic differences were most pronounced for depression and schizophrenia where non-Hispanic blacks were 20% more likely to receive formal psychotherapy for their depression and 2.64 times more likely to receive formal psychotherapy for their schizophrenia when compared to whites.
Conclusions
There were significant racial/ethnic differences in diagnosis and treatment of mental health conditions across 11 U.S. healthcare systems. Further study is needed to understand underlying causes of these observed differences and whether processes and outcomes of care are equitable across these diverse patient populations.
