Abstract

Background: Kentucky has among the highest rate of attention deficit/hyperactivity disorder (ADHD) and stimulant use in the United States. Little is known about this use by race/ethnicity and geography. This article describes patterns of diagnosis of ADHD and receipt of stimulants and psychosocial interventions for children aged 6-17 years receiving Kentucky Medicaid in 2017 and identifies factors associated with diagnosis and treatment.Methods: Using Medicaid claims, children with and without ADHD (ICD-10 codes F90.0, F90.1, F90.2, F90.8, and F90.9) were compared and predictors of diag­nosis and treatment type were examined. Psychosocial interventions were defined as having at least one relevant CPT code. Chi-squared tests and logistic regression models were used for univariate and multivariable analysis, respectively.Results: The rates of ADHD, stimulant use, and psychosocial interventions in our study population exceeded the national aver­age (14% vs 9%; 75% vs 65.5%; and 51% vs 46.5%, respectively). The distributions varied by sex, race/ethnicity, sex among race/ethnicities, and population density. In general, race/ethnicity predicted ADHD diagnosis, stimulant use, and receipt of psy­chosocial interventions with non-Hispanic White children being more likely to receive diagnosis and medication, but less likely to receive psychosocial therapy than other children. Differences were also shown for rural compared with urban residence, sex, and sex within racial/ethnic groups.Conclusions: Diagnosis and treatment modalities differed for children by race/ ethnicity, population density, and sex. More data are needed to better understand whether differences are due to provider bias, child characteristics, or cultural varia­tions impacting the utilization of different treatment options.Ethn Dis. 2021;31(1):67- 76; doi:10.18865/ed.31.1.67
