Introduction: Mortality related to CDH is high, but with great variability among centers. There are few studies on patients with this condition born in South America which show poor outcomes. The goal of this study is to present the outcome of CDH in several high-volume quaternary centers in South America, ascertain the factors associated with lower mortality in our population, and compare our outcomes to those of the CDH Study Group (CDHSG).
Methods: The data from two South American centers were retrospectively analyzed and compared with contemporary data from other CDHSG participating centers. Patient demographic and clinical characteristics were also evaluated and compared.
Results: Between 2013 and 2018, the two South American centers saw 335 patients with CDH with an overall survival rate of 73.1%. Survival for the high, intermediate, and low-risk groups as determined by the Brindle score was 50%, 70%, and 87%, respectively. In our cohort the strongest predictors of mortality were ECMO use and early PaCO2. There were no significant differences in mortality between the two South American centers and the other CDHSG centers when adjusted by risk score, however, the South American centers had higher use of ECMO in the intermediate-risk group.
Discussion: Quaternary South American centers had similar outcomes to CDHSG centers worldwide. The availability and coordination of centralized dedicated care allow more efficient use of scarce technical and professional resources in patients with CDH.
