PURPOSE: The aim of the study was to understand the use of Extracorporeal Membrane Oxygenation (ECMO) in congenital diaphragmatic hernia (CDH) and its outcomes.
METHODS: The 2016 Kid\u27s Inpatient Database (KID) obtained from the national Healthcare Cost and Utilization Project (HCUP) was used to obtain CDH birth, demographic, and outcome data associated with ECMO use. Categorical variables were analyzed and odds ratios (OR) with 95% confidence intervals (CI) are reported for variables found to have significance (p \u3c 0.05). Appropriate regressions were used for comparing categorical and continuous data using SPSS 25 for Macintosh.
RESULTS: The database contained 1189 cases of CDH, of which 133 (11.2%) received ECMO. The overall mortality of neonates with CDH was 18.9% (225/1189). Newborns with CDH on ECMO had a survival of 46% (61/133) compared to 85.5% without ECMO (903/1056) (OR 6.966, p \u3c 0.001, 95% CI 4.756-10.204). ECMO increased length of stay from 24.6 to 69.8 days (OR 2.834, p \u3c 0.001, 95% CI 2.768-2.903) and average cost from 375,002.20to1641,586.83 (OR 4.378, p \u3c 0.001, 95% CI 3.341-5.735).
CONCLUSIONS: Increased length of stay, costs, and outcomes with ECMO use in CDH should prompt an examination of criteria necessitating ECMO
