Key result
EfficientNetB0 and DenseNet121 achieved a prediction accuracy of 88%, slightly outperforming ResNet50 at 87%.
Why the study?
Intraoperative hypotension increases surgical complication rates, and early prediction enables timely interventions to improve patient outcomes.

Machine learning models, including XGBoost and various deep learning architectures, demonstrate high accuracy in predicting clinical events, though the manuscript presents mixed contexts.
The surgical complication rate increases when patients experience Intraoperative Hypotension during operations. Predicting IOH onset early enables swift medical actions that lead to better surgical outcomes for patients. The research implements the Xgboost algorithm to forecast IOH because it exhibits both success in prediction and clear interpretability. Our analysis includes detailed characteristics which merge patient demographic data with surgical data and critical measurements together with anesthesia measurements. These variables are automatically derived from actual surgical data. A performance evaluation of the XgBoost model occurred using standard classification metrics after it processed multi-type data from surgical patients throughout various procedures. The model achieved improved prediction accuracy and decision clarity through implementation of SHAP values. The XgBoost algorithm shows effectiveness in predicting IOH initiation and provides stable clinical decision support. Implementation of this model in surgical operations enables healthcare teams to prevent and manage intraoperative hypotension alongside reduced negative clinical results and increased patient protection.
