Prevalence and early surgical outcome of congenital diaphragmatic hernia in the Netherlands: a population-based cohort study from the European Pediatric Surgical Audit.

Further qualitative analysis to explain this interhospital variation is indicated. Our findings underscore the potential of clinical auditing as a quality measurement tool in rare conditions.
