ABSTRACT
OBJECTIVE:
To understand the implications of a tiered extracorporeal membrane oxygenation (ECMO) criteria framework and the outcomes of patients with COVID-19 acute respiratory distress syndrome who we were consulted on for ECMO but ultimately declined.METHODS:
All patients declined for ECMO support by a large regional health care system between March 2020 and July 2021 were included. Restrictive selection criteria were enacted midway through the study stratifying the cohort into 2 groups. Primary outcomes included 30-day mortality. Secondary outcomes included reasons for declining ECMO and survival stratified by phase.RESULTS:
One hundred ninety-three patients with COVID-19 acute respiratory distress syndrome were declined for ECMO within the study period out of 260 ECMO consults. At the time of consult, 71.0% (n = 137) were mechanically ventilated and 38% (n = 74) were proned and chemically paralyzed. Thirty-day mortality was 66% (n = 117), which increased from 53% to 73% (P = .010) when restrictive criteria were enacted. Patients with multisystem organ failure, prolonged ventilator time, and advanced age had respectively an 11-fold (odds ratio, 10.6; 95% CI, 1.7-65.2), 4-fold (odds ratio, 3.5; 95% CI, 1.1-12.0), and 4-fold (odds ratio, 4.4; 95% CI, 1.9-10.2) increase in the odds of mortality.CONCLUSIONS:
Patients with COVID-19 acute respiratory distress syndrome declined for ECMO represent a critically ill cohort. We observed an increase in the severity of disease and 30-day mortality in consults in the latter phase of our study period. These findings may reflect our use of tiered selection criteria coupled with ongoing education and communication with referring centers, sparing both patients likely to respond to medical therapy and those who were unsalvageable by ECMO.
