Risk stratification for postoperative acute kidney injury in major noncardiac surgery using preoperative and intraoperative data
Importance Acute kidney injury (AKI) is one of the most common complications after
noncardiac surgery. Yet current postoperative AKI risk stratification models have substantial
limitations, such as limited use of perioperative data. Objective To examine whether adding
preoperative and intraoperative data is associated with improved prediction of noncardiac
postoperative AKI. Design, Setting, and Participants A prognostic study using logistic
regression with elastic net selection, gradient boosting machine (GBM), and random forest …
