Racial and ethnic disparities in cardiovascular disease are well established; however, there is limited information about survival differences following veno-venous extracorporeal membrane oxygenation (VV-ECMO) in contemporary adult populations. The purpose of this study was to assess survival at discharge, 30 days, and at 1 year following institution of VV-ECMO in an ethnically diverse population, and to examine potential risk factors for mortality. This was a single-center study of 41 patients (49% female, 27% minorities, 7% > 65 years) who received VV-ECMO between the years 2004 and 2013 at an academic medical center. Kaplan–Meier estimates were calculated to assess survival up to 1 year, and cox proportional hazard models were used to evaluate the association between risk factors, mortality, and confounders. Overall, 76% (n = 31) of VV-ECMO patients survived to discharge and 30 days and 71% (n = 29) survived to 1 year. Whites (n = 30) had a higher survival at 1 year compared to minorities (n = 11) (83% vs. 36%, respectively, p = .01). Minorities had a significantly increased risk of mortality at 30 days (hazard ratio [HR] = 5.07, 95% confidence interval [CI] = 1.42–18.09) and at 1 year (HR = 5.19, 95% CI = 1.63–16.55). Race/ethnicity remained a significant independent predictor of survival at 30 days except when history of shock or lung transplantation was included in adjusted regression models. VV-ECMO was associated with an excellent overall survival up to 1 year. Racial/ethnic minorities had a 5-fold increased risk for 30-day mortality, which was largely explained by a lower likelihood of lung transplantation and increased risk of shock.
