Pediatric pulmonology 2021 year in review: Asthma

Abstract

Asthma is the most common chronic disease in children, affecting an estimated 6.1 million children in the United States. SARS‐CoV2 had a significant impact on asthma exacerbations and healthcare utilization of patients with asthma in 2021. Additionally, studies in 2021 influenced the field of asthma with improvements in diagnostic testing and monitoring, treatment of severe exacerbations, social determinants of health, and evaluation of medical costs. This article is part of our 2021 “Year in Review” series, in which we summarize publications in major pulmonary topics, in the context of selected literature from other journals relevant to our discipline.
