Epidemiology, clinical course, and outcomes of critically ill adults with COVID-19 in New York City: a prospective cohort study

Of 1150 adults admitted to two New York City hospitals with confirmed COVID-19 between early March and April, 22% were critically ill with acute hypoxemic respiratory failure. By the end of April, roughly 40% of the critically ill patients had died, and another 37% were still hospitalized (median length of stay, 33 days). After multivariable adjustment, the strongest predictor of in-hospital mortality was chronic pulmonary disease, followed by chronic cardiovascular disease, older age, and higher concentrations of interleukin-6 and D-dimer at admission. Of note, black and Hispanic patients presented later after symptom onset than did white patients.
