We evaluate real-world diagnostic performance of RSNA COVID-19 consensus reporting guidelines among 2618 chest CT reports from throughout our healthcare network from April 2020 through March 2021; RT-PCR served as reference. "Typical" findings exhibited sensitivity of 68% and specificity of 91%, similar to performance reported in research settings. PPV of only 52% was lower than previously reported, attributed to low COVID-19 prevalence. Accuracy improved from 84% in April 2020 to 92% in March 2021 (p=.03).
