Evaluating the National Surgical Quality Improvement Program-Pediatric Surgical Risk Calculator for Pediatric Craniosynostosis Surgery

Background: The American College of Surgeons' National Surgical Quality Improvement Program-Pediatric (NSQIP-P) risk calculator was developed based on national data. There have been no studies assessing the risk calculator's performance in pediatric neurosurgery. The authors aimed to evaluate the predictions from the risk calculator compared to our single institution experience in craniosynostosis surgery. Methods: Outcomes from craniosynostosis surgeries performed between 2012 and 2016 at our academic pediatric hospital were evaluated using the NSQIP-P risk calculator. Descriptive statistics were performed comparing predicted 30-day postoperative events and clinically observed outcomes. The performance of the calculator was evaluated using the Brier score and receiver operating characteristic curve (ROC). Results: A total of 202 craniosynostosis surgeries were included. Median age was 0.74 years (range 0.15–6.32); 66% were males. Blood transfusion occurred in 162/202 patients (80%). The following clinical characteristics were statistically correlated with surgical complications: American Society of Anesthesiologists physical status classification >1 (P
