Atypical antipsychotic use among Medicaid-insured children and adolescents: duration, safety, and monitoring implications.

Objective: Over the last two decades, the increased use of atypical antipsychotic medications, often for unlabeled indications including attention-deficit/hyperactivity disorder (ADHD), has been profound. This study aims to characterize duration of atypical antipsychotic use by age group and Medicaid eligibility category, and among youth with noncomorbid ADHD.

Methods: Administrative data on 266,590 youth 2-17 years of age, and continuously enrolled in a mid-Atlantic state Medicaid program in 2006, were assessed in terms of median days of atypical antipsychotic use using bivariate analyses and multivariable quantile regression.

Antipsychotic use by medicaid-insured youths: impact of eligibility and psychiatric diagnosis across a decade.

Objective: This cross-sectional study evaluated the impact of Medicaid-eligibility category on the increased use of antipsychotic medication by Medicaid-insured youths across a decade.

Methods: The authors analyzed computerized administrative claims data for 456,315 youths aged two to 17 years who were continuously enrolled in Medicaid in a mid-Atlantic state in 1997 (N=159,171) and 2006 (N=297,144). Bivariate and multivariable analyses quantified changes in antipsychotic use in relation to the youths' psychiatric diagnosis and eligibility category (Temporary Assistance for Needy Families [TANF], state Children's Health Insurance Program [SCHIP], Supplemental Security Income [SSI], and foster care).
