Supplementary materials: Off-label antipsychotic use patterns among Texas Medicaid adults 2013–2016

<b>This is a peer-reviewed supplementary table for the article</b><b> '</b><b>Off-label antipsychotic use patterns among Texas Medicaid adults 2013–2016</b><b>' published in the </b><b><i>Journal of Comparative Effectiveness Research</i></b><b>.</b><b>Supplementary Table 1:</b> Diagnosis and ICD-9-CM, ICD-10-CM Codes<b>Summary: </b><b>Aim:</b> To describe trends in off-label antipsychotic use among Texas Medicaid adults and examine whether demographic and clinical characteristics were associated with off-label use. <b>Methods:</b> Three diagnostic groups (i.e. no diagnosis, on label and off-label) were created based on mental health disorder diagnoses and related antipsychotic prescriptions. <b>Results:</b> During 2013–2016, the prevalence of off-label antipsychotic use decreased from 22.5% to 17.4% and the proportions of no mental health diagnosis remained stable (7.3–9.4%). Patients aged ≥25 years and second-generation antipsychotic users had significantly lower odds of receiving antipsychotics off-label or with no diagnosis. <b>Conclusion:</b> Compared with previous Medicaid database studies, the proportions of off-label antipsychotic use and antipsychotic use with no concurrent psychiatric diagnosis were notably lower.
