Development and validation of risk models for mortality and morbidity in 12 major pediatric surgical procedures: A study from the National Clinical Database-Pediatric of Japan

Japanese researchers developed and validated predictive models for 30-day mortality and morbidity across 12 major pediatric surgical procedures using national registry data. The models demonstrated excellent discrimination (C-index 0.924 for mortality, 0.830 for morbidity), providing surgeons with evidence-based tools to stratify surgical risk and inform preoperative counseling for families.
