We analyze the 2011–2016 Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases for all emergency department visits by children and adolescents in New York to estimate the association between autism spectrum disorder and frequent emergency department utilization. Our study included 5.9 million individuals with 9.1 million emergency department visits. Of those, 31,682 had autism spectrum disorder (0.5%) accounting for 66,053 (0.7%) emergency department visits. Individuals with autism spectrum disorder had on average 0.6 more emergency department visits per year, were more likely to exhibit frequent emergency department use (⩾4, ⩾6, ⩾8, and ⩾10 emergency department visits/year), and had larger shares of comorbidities and diagnoses related to attention-deficit/hyperactivity disorder, intellectual disability, and epilepsy. These findings highlight the need for patient and family-centered care interventions and emergency department staff education initiatives.Lay abstractThis study used data for 5.9 million individuals with 9.1 million emergency department visits from all hospitals in the state of New York to explore frequent emergency department use between children and adolescents with autism spectrum disorders and those without autism spectrum disorders. We found that children and adolescents with autism spectrum disorders had larger shares of comorbidities and diagnoses related to attention-deficit/hyperactivity disorder, intellectual disability, and epilepsy. Children and adolescents with autism spectrum disorders were also more likely to utilize emergency departments and to exhibit frequent use. These results emphasize the need for using family-centered care to improve the care experiences of children and youth with autism spectrum disorders and their families. In addition, the education of emergency department staff of processes and practices as it relates to delivery of care and the care experience.
