Background: Extracorporeal membrane oxygenation (ECMO) use for severe Coronavirus disease 2019 (COVID-19) patients has evolved during the course of the pandemic. Early uncertainty regarding the role of ECMO during the current pandemic was based on the suboptimal initial experiences. However, more recent data suggests favorable outcomes in COVID-19 patients receiving ECMO support. We aimed to explore the epidemiology and outcomes of ECMO for COVID-19 related cardiopulmonary failure and evaluate outcomes of new centers versus established ones.Methods: This is a retrospective, multicenter international, observational study conducted in (19) ECMO centers in five countries from March 1, 2020, to September 30, 2020. We included 307 patients with COVID-19 who received ECMO for refractory hypoxemia and severe respiratory acidosis with or without circulatory failure. Data collection included Patients characteristics, demographic data, ECMO-related specific data, pre-ECMO patient condition, 24 hours post-ECMO initiation data, and outcome. The primary outcome is survival to home discharge. Secondary outcomes include mortality during ECMO, survival to decannulation, and outcomes stratified by center type in which patients were treated.Findings: Three hundred and seven COVID-19 patients received ECMO support during the study period. The median age was 45 years (37-52 IQR), and 81% were men. 178 (58%) patients survived ECMO, of whom 138 (45%) patients were discharged home, and 40 patients (13%) died post-ECMO decannulation while 128 patients (41.7%) died during ECMO. Patient outcomes in the new centers developed in response to the pandemic were similar to those of established centers.Interpretation: During pandemics, ECMO may provide favorable outcomes in highly select patients as resources allow. Outcomes in ECMO centers established during the pandemic were comparable to existing centers.Funding Statement: None.Declaration of Interests: Kiran Shekar acknowledges research support from the Metro North Hospital and Health Service and the Prince Charles Hospital Foundation.
