One of the main challenges of the health crisis caused by the COVID-19 epidemic is the availability of beds in intensive care units (ICUs) and, more importantly, the need for invasive mechanical ventilation (IVM) because the ICUs are currently reserved for intubated patients.

The experiences of both China and Italy indicate that a certain number of COVID-19 patients will require mechanical ventilation. However, the limited number of resuscitation beds and ventilators requires strict use of these scarce resources. As a significant proportion about 5% to 10%, of patients initially admitted to hospital with COVID-19 will require ventilation, it is essential to anticipate their need for resuscitation to improve the rare resource of beds and ventilator shortages in intensive care units.

The hypothesis of the study is that, in proven or suspected hospitalised and oxygen-requiring COVID-19 patients, an early predictive clinical score, calculated over the three first days of admission may allow for an earlier identification of patients who will require intubation and transfer to an intensive care unit for orotracheal intubation
