Purpose: Viral bronchiolitis is a major cause of pediatric intensive care unit (PICU) admission. Insight in the trends of bronchiolitis-associated PICU admissions is limited, but imperative for future PICU resource and capacity planning.

Materials and methods: We retrospectively studied trends in PICU admissions for bronchiolitis in six European sites, including three full national registries, between 2000 and 2019 and calculated population-based estimates per 100,000 children where appropriate. Information concerning risk factors for severe disease and use of invasive mechanical ventilation was also collected when available.

Results: In total, there were 15,606 PICU admissions for bronchiolitis. We observed an increase in the annual number, rate and estimates per 100,000 children of PICU admissions for bronchiolitis at all sites over the last two decades, while the proportion of patients at high risk for severe disease remained relatively stable.

Conclusions: The international increased burden of bronchiolitis for the PICU is concerning, and warrants further international attention and investigation.
