Development and validation of a national perioperative mortality risk model for pediatric surgery: The New Zealand Pediatric Surgical Risk Tool (NZRISK-PEDIATRIC)

New Zealand researchers developed and validated NZRISK-PEDIATRIC, a national risk prediction model estimating perioperative mortality in children undergoing surgery. Unlike existing tools, this model incorporates Australasian data and predicts mortality risk beyond the standard 30-day window, providing clinicians with enhanced decision support for pediatric surgical cases.
