Effect estimate: c-statistic 0.82
A newly developed and validated risk calculator using 7 preoperative variables accurately predicts 30-day mortality after bariatric surgery, aiding in surgical decision-making.
Ramanan et al. (2012) conducted an observational in Morbid obesity (n=32,889). Bariatric surgery mortality risk calculator was evaluated on 30-day postoperative mortality (c-statistic 0.82). A novel risk calculator for 30-day postoperative mortality after bariatric surgery demonstrated excellent predictive performance, achieving a c-statistic of 0.82 in the validation cohort.
