Influence of radiologic pattern and the presence of diffuse parenchymal lung disease on outcome in ventilated patients with COVID-19 pneumonia: impact on prognosis.

Background: Suspected organising pneumonia (OP) is a common finding in patients with severe coronavirus disease 2019 (COVID-19), but the impact on outcomes of the radiological patterns of diffuse parenchymal lung disease on outcome of these patients is still uncertain.

Aims: Investigate the presence of radiological images compatible with OP and its association with clinical outcomes in patients with COVID-19 submitted to invasive mechanical ventilation (IMV).

Methods: Retrospective, unicentric cohort study composed of patients who required IMV and underwent chest computerized tomography to investigate secondary complications of COVID-19.
