Background
COVID-19 is a complex virus that has been spreading since December 2019.
In this study, we aimed to assess the association between chest Computed
Tomography (CT) signs and pejorative evolution, such as death, use of
invasive endotracheal ventilation (IEV) and intensive care unit
hospitalization (ICUH). We also evaluated the diagnostic performance of
chest CT versus the diagnostic gold standard, RT-PCR.
Methods
This retrospective monocentric study included 349 patients who had a
chest CT either for clinical suspicion of COVID-19 pneumonia with severe
initial symptoms, or clinical deterioration in patients with
suspected COVID-19 pneumonia, or clinical deterioration in RT-PCR
positive patients. Principal judgement criteria for pejorative
evolution were: death, IEV, and ICUH.
