In a recent article published in the journal Pediatrics, our research team examined trends in bronchiolitis hospitalizations in the United States. Using a database compiled by the Agency for Healthcare Research and Quality, our group found that from 2000 to 2009 the number of bronchiolitis hospitalizations for children age <2 years decreased by almost 20%. In contrast, during this period both the use of mechanical ventilation (machines that help patients breathe when they are unable to breathe completely on their own) and average hospital costs increased substantially. Our research team suggests that the increased costs are driven by the increased use of intensive resources required to treat children with high-risk medical conditions. The results of this study suggest that more cost-effective strategies are needed to manage bronchiolitis. Hasegawa K, Tsugawa Y, et al.
