Bronchiolitis is the leading cause of infant hospitalizations in the United States. Despite clinical practice guidelines discouraging the utilization of non–evidence-based therapies, there continues to be wide variation in care and resource utilization. A pre-post physician focused educational intervention was conducted with the aims to reduce the use of non–evidence-based medical therapies, including bronchodilators, among patients admitted for bronchiolitis. Among patients meeting inclusion criteria (pre: n = 45; post: n = 47), bronchodilator use decreased by 50% (P < .001). Antibiotic use increased by 9% (P < .02), although results remained within published acceptable utilization rates of less than 19%. There were no statistical differences in chest X-ray, respiratory viral panel, and steroid use. There were no differences in number of pediatric intensive care unit transfers, 30-day readmission rates, and mean length of stay. The findings demonstrate that a physician-focused educational intervention highlighting American Academy of Pediatrics clinical practice guidelines resulted in reduced utilization of bronchodilators.
