Abstract
We used real world data to summarize comorbidities and interventions among patients newly diagnosed with autism spectrum disorder (ASD). Data were derived from two claims-based US healthcare databases; Medicaid and Optum to construct a retrospective cohort of 36,000 patients. Attention-Deficit-Hyperactivity-Disorder (ADHD) was the most common co-morbidity (Medicaid: 50.09%; Optum: 44.16%), followed by mood disorder (Medicaid: 16.56% and Optum: 17.47%). Most patients received at least one type of treatment. Behavioral therapy was common (74.64% in Medicaid and 71.97% in Optum). More than half the cohorts received at least 1 pharmacotherapy. However, pharmacotherapies were diverse. Combination therapy and therapy switching was common. Understanding the clinical diversity and complexity of patients with ASD is an important first step in understanding unmet therapeutic needs.
