We aimed to describe lung ultrasound (LUS) findings in COVID-19 pneumonia and to analyze the association with initial severity and outcome. Prospective cohort study among intensive care unit (ICU) patients in a teaching hospital in Tunisia. A 20-bed respiratory medical intensive care unit of Abderrahmen Mami Teaching Hospital from January to December 2021. We included all COVID-19 pneumonia patients managed in ICU. LUS examination and chest computed tomography (CT), when possible, were performed during the first 24 h of ICU stay. LUS findings were described and association with severity was analysed for trends. During the one-year study period, 311 patients were included with a median age of 58 IQR [47-67] years. ARDS was diagnosed in 307 patients (98. 7%). Median initial PaO/FiO was 112 IQR [81-157] mmHg. Median length of stay was 10 IQR [7-14] days and overall mortality was of 45. 3%. Median LUS score was 29 IQR [25-32]. LUS score gradients were apico-basal and postero-antero-lateral. There was a significant correlation between ROX index and LUS score with r= -0. 146 and p = 0. 013. LUS score above 25 was significantly associated with chest CT damage exceeding 75% (NPV = 80. 7%). LUS score under 25 was significantly associated with chest CT damage
