Risk Stratification of Hospitalized COVID-19 Patients through Comparative Studies of Laboratory Results with Influenza

Category: Article Summary

Topic: Clinical Characteristics and Health Care Setting

• [pre-print, not peer reviewed] Comparing clinical and laboratory results from 719 influenza and 973 COVID-19 patients from January to April, using parameters that are most significantly different between COVID-19 and influenza, COVID-19 patients were sub-classified into 5 clusters through a hierarchical clustering analysis. Risk stratification of these clusters using medical record review found that the highest-risk cluster had a 27.8% case fatality, 94% ICU admission, 94% intubation, and 28% discharge rates (vs. 0%, 38%, 22%, and 88% in the lowest risk cluster).
