When the Coronavirus disease 2019 (COVID-19) pandemic gripped the nation, doctors scrambled to keep up with their patients’ constantly changing and unpredictable outlook. The Feinstein Institutes for Medical Research scientists saw early potential in using diverse patient population data from Northwell Health – New York’s largest health system –and developed a clinical tool to better inform frontline staff on a patient’s prognosis and severity of the disease. Two-and-half-years later, pulling from 35,000 COVID-19 inpatients, researchers published results in Nature Communications detailing how data from basic blood work and other vitals could accurately project a patient’s outcomes and aid in clinical care decision-making.
