This section details the specific machine learning algorithms employed, including logistic regression, decision trees, random forests, and extreme gradient boosting. It outlines the data preprocessing steps, feature selection using Boruta, and model evaluation metrics such as AUC, accuracy, F1 score, recall, and precision. The robust methodology ensures reliable and reproducible results for chronic fatigue prediction.
Explore the comprehensive clinical data collected, encompassing fatigue (MFIS), functional ability (HAQ), disease activity (BVAS), comorbidities, medication use, physical activity, and demographic characteristics. Comparisons between fatigued and non-fatigued GPA patient groups highlight significant differences in acute-phase reactants and prednisone use, underscoring mechanisms beyond simple inflammation.
Understand the broader impact of this research on improving diagnostic capacity in regions with limited access to specialists and enhancing patient quality of life. The discussion covers the significance of key predictors and the potential for machine learning to serve as a powerful clinical tool, along with acknowledged limitations and future directions for advancing AI in rheumatology.

Random Forest Model Achieves Highest Predictive AUC
0.816 AUC in Chronic Fatigue PredictionThe Random Forest model demonstrated superior predictive performance with an AUC of 0.816, outperforming other models in identifying chronic fatigue among GPA patients. This highlights its potential as a robust diagnostic tool.
Identifying the Most Influential Predictors
Our models, particularly Random Forest, identified several critical variables in predicting chronic fatigue. Key factors include: higher disability in activities of daily living (HAQ), older age, and longer disease duration. Other important variables across models included C-reactive protein (CRP) levels and prednisone dose. These findings align with known mechanisms of chronic fatigue in rheumatic diseases, providing a comprehensive view for targeted interventions.
Streamlined Diagnostic Workflow with AI
Leveraging machine learning, the diagnostic process for chronic fatigue in GPA patients can be significantly streamlined and enhanced, moving from time-consuming traditional methods to an efficient, data-driven approach.

Our phased approach ensures a smooth and effective integration of machine learning models into your existing clinical workflows, maximizing benefits while minimizing disruption.
Data Preparation & Model Training
Collect and preprocess historical clinical data, including MFIS, HAQ, BVAS, and demographic details. Train and validate initial ML models (Logistic Regression, Decision Tree, Random Forest, XGBoost) using a 70/30 train-test split. Conduct feature selection with Boruta.
Model Validation & Refinement
Evaluate model performance using AUC, accuracy, F1 score, recall, and precision. Identify key predictive variables like HAQ score, age, and disease duration. Refine models based on clinical relevance and performance metrics to ensure robustness.
Pilot Deployment & Feedback
Integrate the optimized ML model into a pilot clinical setting with limited specialist access. Collect feedback from rheumatologists and clinicians on usability and diagnostic support. Monitor real-world performance against traditional methods.
Full-Scale Integration & Continuous Improvement
Roll out the AI diagnostic tool across broader clinical settings. Establish a continuous learning loop for model updates and improvements with new data. Provide ongoing training and support for healthcare professionals.
