Trends in U.S. hospitalizations for anaphylaxis among infants and toddlers: 2006-2015.

Background Anaphylaxis is a potentially fatal acute allergic reaction. Its overall prevalence appears to be rising, but little is known about U.S. hospitalization trends among infants and toddlers. Objective To identify the trends and predictors of hospitalization for anaphylaxis among infants and toddlers. Methods We used the nationally representative National Inpatient Sample (NIS), from 2006-2015, to perform an analysis of trends in U.S. hospitalizations for anaphylaxis among infants and toddlers (age Conclusion Anaphylaxis hospitalizations among infants and toddlers in the US were stable from 2006-2015, while hospitalizations among older children were rising. Future research should focus on the trends in disease prevalence and healthcare utilization in the understudied population of infants and toddlers.
