Explainable machine learning for postoperative respiratory failure prediction in open-heart surgery patients — a study based on the MIMIC-IV database

Puntos clave

The study aims to enhance the predictability of postoperative respiratory failure using machine learning techniques.
Utilized the MIMIC-IV database for data analysis
Implemented a Gradient Boosting Machine (GBM) model for prediction
Conducted SHAP analysis to interpret model outputs
The GBM model achieved balanced performance in discrimination and calibration.
SHAP analysis revealed critical hemodynamic and metabolic markers affecting PRF predictions.

Resumen

The GBM model, selected for its balanced performance across discrimination, calibration, and validation stability, provides a promising tool for early PRF risk stratification. The use of SHAP analysis enhances the interpretability of the model, highlighting the role of hemodynamic and metabolic markers in predicting PRF, thus improving clinical understanding and decision-making.
