Sparks B, et al. - Whether constipation in children with autism spectrum disorder (ASD) was associated with increased Emergency Department (ED) visits and inpatient admissions compared with constipation in children without ASD was evaluated in this investigation. Between 2006 and 2014, the Nationwide Emergency Department Sample was used to retrospectively examine demographic data, clinical characteristics, and outcomes of children with ASD and children without ASD who visited the ED for constipation. The findings demonstrated that constipation was responsible for a large proportion of ED visits and more inpatient admissions resulting from these ED visits. For constipation in children with ASD, there was a need for developing more effective outpatient therapies.
