Impact of Ondansetron Prescription on Return Emergency Department Visits Among Children with Acute Gastroenteritis.

Objectives: The objective of this study was to determine if providing ondansetron prescription to children with acute gastroenteritis seen in the emergency department (ED) is associated with reduced unscheduled ED revisits.

Methods: This was a retrospective comparative cohort study conducted in a tertiary urban pediatric ED. We evaluated otherwise healthy children 6 months to 18 years old who presented to the ED between 2010 and 2015 and were discharged home with acute gastroenteritis diagnosis.
