To normalize across sites with a small number of total cases, we generated the rate of growth of total admissions by country per day. In Figure 3 , we compared those values with Johns Hopkins-curated data 24 over time. Rates of growth as extracted from EHR data from our sites were similar to population-level findings during the month of March. Of note, national data from Singapore did not track with EHR numbers. Our one site in Singapore had a small number of patients and is less likely to be representative of all hospitals in the country.
