ABSTRACT
OBJECTIVES:
Determine the factors associated with mortality in venovenous extracorporeal membrane oxygenation (V-V ECMO) patients with COVID-19 infection and provide an updated report of clinical outcomes for patients treated with V-V ECMO for COVID-19 in Minnesota.DESIGN:
Multicenter prospective observational study.SETTING:
The four adult Extracorporeal Life Support Organization-certified Centers of Excellence in Minnesota. PATIENTS A total of 100 patients treated with V-V ECMO for COVID-19-associated acute respiratory distress syndrome (ARDS) from March 2020 to May 2021.INTERVENTIONS:
Not applicable. MEASUREMENTS AND MAINRESULTS:
The primary outcome was 60-day survival for patients treated with V-V ECMO for COVID-19. Outcomes of patients treated from November 2020 to May 2021(cohort 2) were compared with data from a previous cohort of patients, collected from March 2020 to October 2020 (cohort 1). The data from both cohorts were merged into a single dataset (Combined Cohort). Survival on V-V ECMO due to COVID-19-associated ARDS significantly decreased after October 2020 (63% vs 41%; p = 0.026). The median interval from hospital admission to V-V ECMO cannulation was significantly associated with 60-day mortality (10 d [6-14 d] in nonsurvivors vs 7 d [4-9 d] in survivors; p = 0.001) in the Combined Cohort and was also significantly longer in cohort 2 than cohort 1 (10 d [7-14 d] vs 6 d [4-10 d]; p < 0.001). In the Combined Cohort, the 60-day survival for patients who did not receive steroids was 86% (n = 12) versus 45% (n = 39) for patients who received at least one dose of steroids (p = 0.005).CONCLUSIONS:
There was a significant increase in mortality for patients treated with V-V ECMO for COVID-19-associated ARDS in cohort 2 compared with cohort 1. Further research is required to determine the cause of the worsening trend in mortality.
