Abstract
OBJECTIVE: The outcome of patients with congenital diaphragmatic hernia (CDH) has not improved in the last decade and surgical repair remains the mainstay of treatment. The purpose of the present study was to assess whether a volume-outcome relationship exists in the U.S. academic medical centers performing surgical repair of neonatal CDH. STUDY DESIGN: A retrospective cross-sectional analysis of discharge data for neonates undergoing CDH repair in academic medical center members of the University Health-System Consortium was employed. Unadjusted mortality was compared between lower and higher surgical volume centers. A binary logistic regression model was fit to test the relationship of surgical volume with mortality. RESULTS: A total of 3,738 patients underwent surgical repair in 122 unique academic medical centers in the United States. The overall rate of survival was 75.2%. There was no difference in unadjusted mortality between lower and higher volume centers. After controlling for patient and hospital variables, there was no difference in the odds of mortality between lower and higher volume centers (odds ratio 1.03 [95% confidence interval, 0.86-1.23, p = 0.730]). CONCLUSIONS: Neonates born with congenital diaphragmatic hernia can undergo surgical repair in the U.S. academic medical centers independent of center procedure volume and expect good surgical outcomes.
