The Atellica COVID-19 Severity Algorithm is a model designed to help predict the potential likelihood of progression to severe disease and life-threatening multi-organ dysfunction in COVID-19 patients. In addition to patient age, D-dimer, Lactate dehydrogenase (LDH), Lymphocyte %, Eosinophil %, Creatinine, C-reactive protein (CRP), Ferritin, PT-INR, and high-sensitivity Cardiac Troponin-I are used to help predict the likelihood of disease progression to severe disease endpoints. By entering a potential patient’s lab values and age, the algorithm will generate a COVID-19 clinical severity score, including projected probability of progression to ventilator use, end-stage organ damage, and 30-day in-hospital mortality.
