Baek MS, et al. - Whether the Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score is applicable to older patients was investigated using a Korean cohort with median age 58 (IQR, 45–65) years treated with extracorporeal membrane oxygenation (ECMO) for acute respiratory failure (ARF). Overall survival at hospital discharge was 45.9%, and veno-venous ECMO was used in 82.3% of patients. In a Korean ECMO population, the RESP score was recognized as a significant model for predicting outcomes. Age was identified as an independent risk factor for hospital mortality on multivariate logistic regression. Higher mortality was noted in elderly patients. Relative to the RESP score, age alone showed similar discrimination ability for prediction of mortality.
