Bronchiolitis: Safely Doing Less Is the Next Big Thing.

Bronchiolitis is a viral lower respiratory tract infection primarily affecting children younger than 2 years; a common cause of health care encounters, including hospitalization; and a considerable economic burden for health care systems in the United States and worldwide. The American Academy of Pediatrics (AAP) most recently updated its bronchiolitis guideline in 2014 and reaffirmed supportive care as the mainstay of treatment. Despite these recommendations, there is still significant variability in care provided for these children, especially in bronchodilator usage, radiography, and high-flow nasal cannula. Since the 2014 AAP guideline, many pediatric hospitalists have undertaken quality initiatives to improve the adherence to published guidelines, yet a large gap remains between what is recommended and what is practiced. This article presents research on the efficacy of common interventions as well as an introduction to diagnostics and treatments potentially on the horizon. [Pediatr Ann. 2024;53(6):e223-e228.].
