Diagnostic Testing and Antibiotic Use in Young Children With Community-Acquired Pneumonia in the United States, 2008-2015.

Diagnostic testing and antibiotics are not routinely recommended for young children with community-acquired pneumonia. In a national sample of >6 million outpatient 1- to 6-year-olds with community-acquired pneumonia between 2008 and 2015, a complete blood count was obtained for 8.6% (95% confidence interval [CI], 6.1%-11.1%), radiography was performed for 43% (95% CI, 36%-50%), and antibiotics were given for 73.9% (95% CI, 67.1%-80.7%). There were no changes in testing or antibiotic use over time.
