Describing patterns of pediatric allergies across the United States using EHR

In the largest study of its kind, researchers from Children’s Hospital of Philadelphia (CHOP) used electronic health record (EHR) data from more than 200,000 pediatric patients to describe patterns of pediatric allergies across the United States, validating a population-level pattern of allergy development known as the “allergic march,” in which allergies first present as eczema, followed by food allergies, asthma, and environmental allergies.
