Machine Learning Models for Prediction of Acute Kidney Injury After Noncardiac Surgery

Completed

• Conditions: Postoperative Acute Kidney Injury

• Registration Number: NCT06146829
• Lead Sponsor: Rao Sun

Brief Summary

Acute kidney injury (AKI) is a common surgical complication characterized by a rapid decline in renal function. Patients with AKI are at an increased risk of developing chronic kidney disease and end-stage renal disease, which has been associated with an increased risk of morbidity, mortality and financial burdens. Identifying high-risk patients for postoperative AKI early can facilitate the development of preventive and therapeutic management strategies, and prediction models can be helpful in this regard.

The goal of this retrospective study is to develop prediction models for postoperative AKI in noncardiac surgery using machine learning algorithms, and to simplify the models by including only preoperative variables or only important predictors.
