Psychotropic Medication Prescribing: Youth in Foster Care Compared with Other Medicaid Enrollees

Abstract

Objective: To compare the prevalence of psychotropic medication dispensing among youth in foster care with those among nonfoster youth on Medicaid. Methods: Children ages 1–18 years in a region of a large southern state who were enrolled in their respective Medicaid plan for at least 30 days between 2014 and 2016 and had at least one health care claim were included. Medicaid prescription claims were categorized by class: alpha agonists, anxiolytics, antidepressants, antipsychotics, mood stabilizers, and stimulants. Primary mental health (MH) or developmental disorder (DD) diagnostic groups were identified for each class. Analyses included chi-square tests, t -tests, Wilcoxon sign rank tests, and logistic regression. Results: A total of 388,914 nonfoster and 8426 children in foster care were included. Overall, 8% of nonfoster and 35% of foster youth were dispensed at least one prescription for a psychotropic medication. Prevalence was higher for youth in care within each drug class and, with one exception, across all age groups. Among children dispensed a psychotropic medication, the mean number of drug classes dispensed was 1.4 (SD 0.8) and 2.9 (SD 1.4) for nonfoster and foster youth, respectively ( p < 0.000). Except for anxiolytics and mood stabilizers, more children in foster care were dispensed psychotropic medications without an MH or DD diagnosis. Finally, children in foster care experienced 6.8 (95% CI: 6.5–7.2) times higher odds of being dispensed a psychotropic medication than their nonfoster peers, after controlling for age group, gender, and number of mental and developmental diagnoses. Conclusions: Across all age groups, children in foster care on Medicaid were dispensed psychotropic medications disproportionately more than their nonfoster peers on Medicaid. In addition, children in foster care were significantly more likely to dispense psychotropic medication absent an MH or DD diagnosis.
