Area of Science:

Medical Informatics
Machine Learning in Healthcare
Predictive Analytics

Background:

Machine learning (ML) models offer advanced capabilities for capturing complex, nonlinear interactions in data.
However, the 'black box' nature of many ML models limits their clinical interpretability and adoption.
There is a need for ML tools that balance predictive power with transparency.

Purpose of the Study:

To develop and validate a novel, interpretable machine learning-based scoring system for predicting perioperative stroke.
To leverage SHapley Additive exPlanations (SHAP) values for enhanced model comprehension.
To create an efficient and clinically applicable risk assessment tool.

Main Methods:

Developed the Explainable Automated nonlinear Computation scoring system for Health (EACH) framework.
Utilized a CatBoost model, identified key predictive features, and employed SHAP plots to pinpoint critical change points.
Normalized the EACH score and validated its performance on independent patient cohorts from different institutions.

Main Results:

The EACH score achieved an Area Under the Curve (AUC) of 0.829 for perioperative stroke prediction in a large cohort (n=38,737).
External validation confirmed its superior predictive accuracy (AUC=0.784) compared to traditional scores (AUC=0.528) and alternative ML models (AUC=0.564).
Demonstrated robust performance on geographically and temporally distinct datasets.

Conclusions:

The EACH score represents a precise and explainable machine learning-based risk prediction tool.
Its effectiveness is validated in real-world clinical data, outperforming existing methods.
EACH offers a promising advancement for predicting perioperative stroke risk.
