Trazodone Prescribing for Children With Attention Deficit Hyperactivity Disorder on Medicaid in Oregon

Abstract

OBJECTIVE To examine trazodone prescribing to Medicaid-insured children with a diagnosis of attention deficit hyperactivity disorder (ADHD) from 2012 to 2016 for patient-level factors, including coexisting diagnoses associated with trazodone prescriptions. METHODS A retrospective cohort study used de-identified claims data from the Oregon Health Authority to analyze associations, frequency, and likelihood of new trazodone fills. RESULTS A total of 16,547 trazodone prescriptions were identified, representing 8.4% (n = 2,705) of 32,134 children. Most were filled for children ages 10 years and older. Children with ADHD were predominantly male (70.7%); however, more female children had a filled trazodone prescription compared with males (10.1% vs 7.7%). Female and male children with a filled trazodone prescription shared common diagnoses in the top 10 rank, although episodic mood disorders, such as bipolar disorder (International Classification of Diseases, Ninth Revision, Clinical Modification, diagnosis code 296) were only noted for female children. Female children were significantly older at the time of the first filled trazodone prescription (12.5 years; 95% CI, 12.3–12.7) compared with male children (12.0 years; 95% CI, 11.8–12.1). Modified Poisson regression models found children with ADHD and a filled trazodone prescription were 3 times more likely to have a sleep-related diagnosis as their most common diagnosis (excluding ADHD), compared with those of the same age and sex without a trazodone prescription (RR, 2.94; 95% CI, 2.44–3.54). CONCLUSIONS Children with ADHD are prescribed trazodone off label and for conditions with no national guidelines or clinical evidence of efficacy. Female children on Medicaid may be prescribed trazodone for concurrent mental health conditions, and further research is warranted regarding potential correlates.
