Clinical Influenza Testing Practices in Hospitalized Children at United States Medical Centers, 2015-2018

J Pediatric Infect Dis Soc. 2021 Oct 13;piab096. doi: 10.1093/jpids/piab096. Online ahead of print.


At nine US hospitals that enrolled children hospitalized with acute respiratory illness (ARI) during 2015-2016 through 2017-2018 influenza seasons, 50% of children with ARI received clinician-initiated testing for influenza and 35% of cases went undiagnosed due to lack of clinician-initiated testing. Marked heterogeneity in testing practice was observed across sites.
