Determinants of long-term outcomes in patients with COVID-19 supported with ECMO
We read with great interest the EuroECMO-COVID study1 in The Lancet Respiratory Medicine. Roberto Lorusso and colleagues should be congratulated for this important research, which contributes to our understanding of the long-term outcomes of COVID-19 in the most severe forms of disease treated with extracorporeal membrane oxygenation (ECMO). However, we would like to draw attention to missing data that could have had a key role in lung recovery, extended ECMO duration, and associated complications.
