Abstract P131: Is Older Age (≥ 65 years old) Associated with Increased Mortality Following Extra-Corporeal Membrane Oxygenation?

Background: Extra-corporeal membrane oxygenation (ECMO) is increasingly being used as a life-saving bypass technique for patients whose acute cardiopulmonary failure is potentially reversible and refractory to conventional care. Prognostic data for ECMO among diverse patients are limited. The purpose of this study was to evaluate the association between age (≥ 65 vs. <65 years) and 1-year mortality after ECMO, adjusted for confounders. Methods: This was a retrospective cohort analysis of 131 consecutive adult patients (28% ≥65 years old, 26% racial/ethnic minority, 38% female) enrolled in an ECMO database who received veno-arterial ECMO at an academic medical center between 2004-2013. Demographics, comorbid conditions, admission characteristics, and mortality status at 1 year were obtained from the hospital clinical information system, updated monthly with Social Security Death Index data. Univariate and multivariate adjusted Cox proportional hazard analyses were conducted to evaluate the associations bet...
