Hospital-level variation in diagnostic testing for children with AGE evaluated in the ED and discharged from (A) or admitted to (B) the hospital. Hospital-level variation in diagnostic testing for children with AGE evaluated in the ED and discharged from (A) or admitted to (B) the hospital. Box plots represent the hospital-level median (vertical line within each box), IQR (box ends), and 1.5 times the IQR (whiskers) proportion of patients at each hospital receiving diagnostic testing. Solid circles represent patient-level medians across all hospitals. Chemistry profiles include BMP and CMP; stool studies include rotavirus antigen, stool cultures, and Clostridium difficile antigen.
