^aCH1 and CH2 represent our two community pediatric hospitals and are subsets of “Community.” The relatively low numbers limit definitive conclusions but they suggest that CH2 is a location where additional efforts might be focused. Of note, CH2 lacks a neonatal intensive care unit (NICU) and is staffed by a heterogeneous group of physicians who rotate from the main teaching hospital, which might account for fewer cases overall and the lowest percentage of US-only diagnoses determining surgical disposition. In distinction, CH1 has a NICU and uses a dedicated physician staffing model
