Abstract

Abstract : Simple tests of routine data are needed for those with severe acute respiratory syndrome coronavirus 2, which causes corona virus disease 2019 (COVID‐19), to help identify those who may need mechanical ventilation (MV). In this study, we aimed to determine if fibrosis‐4 (FIB‐4) is associated with the need for MV in patients with COVID‐19 and if there is an association to determine the optimal FIB‐4 cutoff. This was a retrospective, national, multiethnic cohort study of adults seen in an ambulatory or emergency department setting who were diagnosed with COVID‐19. We used the TriNetX platform for analysis. Measures included demographics, comorbid diseases, and routine laboratory tests. A total of 4, 901 patients with COVID‐19 were included. Patients had a mean age of 56, 48% were women, 42% were obese, 38% were white, 40% were black, 15% had cardiac disease, 39% had diabetes mellitus, 20% had liver disease, and 50% had respiratory disease. The need for MV was 6%. The optimal FIB‐4 cutoff for the need for MV was 3.04 (area under the curve, 0.735), which had sensitivity, specificity, and positive and negative predictive values of 42%, 77%, 11%, and 95%, respectively, with 93% accuracy. When stratified by race, increased FIB‐4 remained associated with the need for MV in both white and black patients. Conclusion: FIB‐4 can be used by frontline providers to identify patients that may require MV. Abstract : The FIB‐4 index, a simple tool of routine clinical data, was found to independently be associated with need for mechanical ventilation in patients with COVID‐19.image
