Patient Demographics Are Associated With Testing for Group A Streptococcal Pharyngitis in Children.

Among a retrospective cohort of 65 786 outpatient encounters for children >3 years with acute respiratory tract infection at an academic institution in 2023, 38 790 (59%) had a rapid group A streptococcal (GAS) test ordered. Testing rates differed significantly by race, ethnicity, insurance type, social vulnerability index, visit location, and clinician type, and children in historically underserved and socially vulnerable groups were less likely to undergo GAS testing compared to their social counterparts.
