To examine the psychiatric medication fill rates of adolescents after release from juvenile detention. The team reviewed 177 charts. A fill was defined as a psychiatric medication charge to Medicaid 30- or 90-days after release. Differences in demographic characteristics were compared among individuals with fills at 30- or 90-days and those with no medication fills. Forty-five percent of patients were on at least one psychiatric medication. Among detainees on a psychiatric medication, 62 % had a fill by 30 days after release, and 78 % by 90 days. At least 50 % of the adolescents on a psychiatric medication were on an atypical antipsychotic. There was no significant relationship between medication fill and race, age, or sex. Despite the known associations between mental health diagnosis and treatment-seeking with age, sex, and race, it appears that psychiatric medication fill patterns after release from detention are not associated with these factors.
