Only 5% of patients infected with COVID-19 develop severe or critical Coronavirus disease 2019 (COVID-19) and there is no reliable risk stratification tool for non-severe COVID-19 patients at admission. Finding a way to predict which patients with an initial mild to moderate presentation of COVID-19 would develop severe or critical form of COVID-19 according to CT-scan data, simple clinical and biological parameters is challenging. In this multicentric study, the study aims to construct a predictive score for early identification of cases at high risk of progression to moderate, severe or critical COVID-19 combining simple clinical and biological parameters and qualitative, quantitative or artificial intelligence (AI) data from the initial CT from non-severe patients.
A few numbers of patients infected with Coronavirus disease 2019 (COVID-19) rapidly develop
acute respiratory distress leading to respiratory failure, with high short-term mortality
rates. However, only 5% of patients infected with COVID-19 are concerned by this pejorative
evolution. At present, there is no reliable risk stratification tool for non-severe COVID-19
patients at admission.
Chest computed tomography (CT) is widely used for the management of COVID-19 pneumonia
because of its availability and quickness. The standard of reference for confirming COVID-19
relies on microbiological tests but these tests might not be available in an emergency
setting and their results are not immediately available, contrary to CT. In addition to its
role for early diagnosis, CT has a prognostic role through evaluating the extent of COVID-19
lung abnormalities.
Finding a way to predict which patients with an initial mild to moderate presentation of
COVID-19 would develop severe or critical form of COVID-19 according to CT-scan data, simple
clinical and biological parameters is challenging. In this multicentric study, the study aims
to construct a predictive score for early identification of cases at high risk of progression
to moderate, severe or critical COVID-19 combining simple clinical and biological parameters
and qualitative, quantitative or artificial intelligence (AI) data from the initial CT from
non-severe patients. The final objective is to organize optimal patient management in the
appropriate health structure.
Inclusion Criteria:
- First chest CT, assessed for respiratory symptoms, without injection of contrast agent
for respiratory symptoms, and whose results of the CT subjective visual analysis are
compatible or typical of COVID-19
- biological diagnosis of COVID-19 (RT-PCR) or clinical suspicion (cough and / or
dyspnea and / or fever and / or need to use oxygen therapy as part of routine care) at
the time of the examination
- Authorization of the patient for the processing of his personal data, except CNIL
exemption
Exclusion Criteria:
- Patient with a moderate (oxygen between 3 and 5 L / min to achieve saturation greater
than 97% and a respiratory rate <25 / min without the need for invasive ventilation),
severe form (oxygen therapy> 5L / min to obtain a SpO2> 97%) or critical form (need to
resort to ventilation and / or orotracheal intubation) at the date of the first chest
CT
- Age < 18 years old
- Patient deprived of liberty by judicial decision
