We collect clinical and radiological data, the treatment received (ventilatory support and CC) and radiological features (thoracic CT) at 12 monthsResults: Of a total of 109 admitted patients, 23 died during hospital stay. 78 patients were followed up. 69% were men; mean age 61 (±11) years. 49% required invasive ventilation (IV), 27% non-invasive positive pressure support (NIV), and 24% high-flow nasal cannula oxygen therapy (HFNC). 66% received CC therapy Of the 71 patients who were followed up at year, 31% presented normal radiology, 7% ground glass opacities, 53.5% reticulum and 8.5% fibrosis. In relation to residual/fibrotic sequelae, a higher proportion was observed in >60 years (73.9% vs 40%; p=0.005) and in patients who required IV, compared to NIV and HFNC (73.5% vs 61.9 vs 37.5%; p=0.05), with no significant differences in the use of CC (72.1% vs 55.6%; p=0.156) In the multivariate analysis, age (>60 years) and invasive ventilation were associated with the presence of pulmonary sequelae (OR 3.92 [95% CI 1.31-11.75]) and (OR 3.85 [95% CI 1.01-14.64])Conclusions: 8.5% of patients presented pulmonary fibrosi at 1 year. Age (>60) years and invasive ventilation were related to a higher frequency of pulmonary radiological sequelae, regardless of administration of CCFootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 1882.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
