Table 3.

Proportion of chart-reviewed patients admitted specifically for COVID-19 vs admitted with incidental SARS-CoV-2, overall and stratified by site, with a detailed criteria breakdown. A detailed breakdown at site D could not be included, because their process did not record the specific criteria for each classification. Note that cells with 0% are still included to show all the chart review criteria.
