Effect of hospital case volume on outcome in congenital diaphragmatic hernia: the experience of the Canadian Pediatric Surgery Network.

摘要

PURPOSE: Despite advances in neonatal care of congenital diaphragmatic hernia (CDH), a significant variation exists in the mortality rates reported by individual centers.

Anonymized hospitals were categorized as either high (>6 cases) or low-volume (
