Methods: retrospectively collect clinical data—demographics, comorbidities, vital signs, critical illness scores, and laboratory tests—from MIMIC-IV, eICU, and Zhongnan Hospital of Wuhan University, then train LightGBM, decision tree, XGBoost, random forest, ensemble model and conventional logistic regression, evaluating performance with ROC and interpreting features with SHAP. Results: ensemble achieves the highest AUC across internal, eICU, and hospital validations, surpassing logistic regression. Conclusion: machine learning provides superior AKI prediction for critically ill CS.","International Journal of General Medicine downloaded from [https://www.dovepress.com/](https://www.dovepress.com/)  \nFor personal use only.  \nInternational Journal of General Medicine  \nOpen Access Full Text Article ORIGINAL RESEARCH  \nPrediction of Acute Kidney Injury for Critically Ill Cardiogenic Shock Patients with Machine Learning Algorithms  \nXiaofei Zhang 1 , *, Yonghong Xiong2 , *, Huilan Liu 3 , Qian Liu4 , Shubin Chen 5  \n1Department of Gerontology, China Aerospace Science & Industry Corporation 731 hospital, Beijing, People’s Republic of China; 2Department of Cardiology, Beijing Feng Tai Hospital, Beijing, People’s Republic of China; 3Department of Nephrology, Zhongnan Hospital of Wuhan University, Wuhan, People’s Republic of China; 4Department of Cardiology, Wuhan Children’s Hospital, Tongji Medical College, Huazhong University of Science & Technology, Wuhan, People’s Republic of China; 5Department of Intensive Care Unit, China Aerospace Science & Industry Corporation 731 hospital, Beijing, People’s Republic of China  \n*These authors contributed equally to this work  \nCorrespondence: Qian Liu, Department of Cardiology, Wuhan Children’s Hospital, Tongji Medical College, Huazhong University of Science & Technology, No. 100 of Xianggang Road, Jiangan District, Wuhan, 430015, People’s Republic of China, Tel +86027-82433350, Email qian_l[iu1124@126.com](iu1124@126.com); Shubin Chen, Department of Intensive Care Unit, China Aerospace Science & Industry Corporation 731 hospital, No. 3 Zhen Gang Nan Li, Yun Gang Town, Feng Tai District, Beijing, 100074, People’s Republic of China, Tel +86010-68374065, Email [18610074016@163.com](18610074016@163.com)  \n\n| Background: The aim of this study was to use five machine learning approaches and logistic regression to design and validate the acute kidney injury (AKI) prediction model for critically ill individuals with cardiogenic shock (CS) .\u003Cbr>Methods: All patients who diagnosed with CS from the MIMIC-IV database, the eICU database, and Zhongnan hospital of Wuhan university were included in this study. Clinical information, including demographics, comorbidities, vital signs, critical illness scoresand laboratory tests was retrospectively collected. Five machine learning algorithms (LightGBM, decision tree, XGBoost, random forest, and ensemble model) and one conventional logistic regression were applied for the prediction of AKI in critically ill individuals with CS. ROC curves were generated via python software to assess the overall performance of machine learning algorithms and the SHAP analysis was adopted to reveal the impact of prediction for each feature.\u003Cbr>Results: The ensemble model exhibited the best predictive ability (AUC:0.91, 95% CI, 0.88–0.94), followed by random forest (AUC:0.90, 95% CI, 0.86–0.94) and XGBoost (AUC:0.89, 95% CI, 0.84–0.92) . While the logistic regression model obtained the worst predictive performance (AUC:0.62, 95% CI, 0.56–0.68) . When validated the prediction models with eICU database, the ensemble model exhibited the best predictive ability (AUC:0.92, 95% CI, 0.89–0.96), while the logistic model obtained the worst predictive performance (AUC:0.61, 95% CI, 0.56–0.67) . Finally, we verified the prediction models using the data from our hospital and ensemble model still exhibited the best predictive ability (AUC:0.74, 95% CI, 0.62–0.86), while the decision tree model obtained the worst\u003Cbr>predictive performance (AUC:0.52, 95% CI 0.35–0.70) .\u003Cbr>Conclusion: Machine learning algorithms could be utilized for the AKI prediction among critically ill CS patients, and exhibit superior predictive performance compared to the conventional logistic regression analysis.\u003Cbr>Keywords: cardiogenic shock, acute kidney injury, MIMIC database, prediction
