In patients with COVID-19 pneumonia, Lung Ultrasound Signs (LUS) signs, including the aeration score, were related to respiratory and systemic symptoms 1 month after ultrasound screening examination. In these patients, a strong relationship was also found between LUS findings and poor outcomes, such as the need for hospitalization (including in the ICU) and death.

Future studies should evaluate the relationship between LUS signs at the time of diagnosing lung involvement and long-term consequences.

According to the evaluations performed 1 month after LUS screening, 36 patients were hospitalised, eight of whom required ICU admission and three of whom died. The presence of coalescent B-lines was associated with the need for hospitalization (p = 0.008).

This was a retrospective study of data prospectively collected 1 month after LUS screening of 447 adult patients diagnosed with COVID-19 pneumonia.
