Consolidation-to-ground-glass opacity ratio on chest CT as a prognostic marker for critical outcomes in COVID-19: a retrospective cohort study.

ABSTRACT:

Background

Computed tomography (CT)-based quantification of coronavirus disease 2019 (COVID-19) pneumonia is widely performed, and total pneumonia volume, ground-glass opacity (GGO), and consolidation affect disease severity. However, there is insufficient information on how consolidation to GGO (C/G) ratio correlates with clinical characteristics including disease severity and complications in COVID-19 patients.

Methods

This retrospective cohort study included 1,194 hospitalized patients with COVID-19 from four member hospitals of the Japan COVID-19 Task Force. Critical outcomes were defined as conditions requiring high-flow oxygen or invasive mechanical ventilation, or death. Patients were divided into two groups based on %pneumonia (percentage of pneumonia volume divided
