Study design and population
This study was a retrospective observational cohort study of patients
discharged after an emergency visit with an EAI prescription from either
of two affiliated pediatric EDs, an academic urban pediatric ED with an
annual census of 90,000 patient visits and a satellite urban
free-standing pediatric ED with an additional 30,000 annual patient
visits. We included data from patients that presented over a 22-month
period from January 1,2018 to October 31, 2019. Patients were excluded
if they were not prescribed an EAI or if we could not determine their
prescription fill status. EAI prescription fill status could be
indeterminate because the patient received a handwritten prescription,
had a prescription called into the pharmacy by phone or used a pharmacy
that did not participate inSureScriptse-prescribing during the study
period. The Institutional Review Board approved this study.
