Conclusions
AKI, acute kidney injury, postoperative AKI
It is feasible by using the model to identify persistent AKI after cardiac surgery in patients with normal baseline renal function who experienced postoperative AKI, which may aid in patient stratification and individualized precision treatment strategy.Among 5368 patients with baseline normal renal function and acute kidney injury (AKI) after cardiac surgery, 3768 patients were randomly used for model development and the rest for validation. We developed a model for predicting postoperative persistent AKI. The model's performance was good in the validation group.
