A Risk-Oriented and Explainable Hierarchical AI Framework for Chronic Kidney Disease Classification
This study presents a novel hierarchical AI framework for Chronic Kidney Disease (CKD) classification, focusing on early risk identification and explainable decision support using real-world laboratory data. It achieves high accuracy in both binary CKD detection and multi-stage classification, providing transparent, clinically aligned insights for preventive nephrology.
Executive Impact
Our analysis reveals significant opportunities for your enterprise to leverage AI for improved clinical decision-making, early disease detection, and enhanced patient outcomes. The robust performance and explainability of this framework translate directly into tangible benefits.

Framework Overview
The proposed framework integrates binary classification (CKD vs. non-CKD), multi-stage classification (stages 3-5), and a risk-oriented assessment. This hierarchical design mirrors clinical workflows, ensuring disease presence is established before severity assessment. It prioritizes robustness to data variability and controlled interpretability through SHAP explanations.
Clinical Relevance
The system’s design directly addresses the need for predictive systems that align with routine clinical workflows, using commonly ordered laboratory panels. It provides transparent, interpretable decision support, enhancing clinical trust and supporting targeted interventions before overt disease onset. The consistency of selected features (e.g., CREA, BUN, HGB) across models validates its clinical meaningfulness.
Robust CKD Detection Performance
97% Binary CKD Classification Accuracy (XGBoost + RFE)The framework achieved 97% accuracy and F1-score in binary CKD classification, and 0.99 AUC, demonstrating its ability to reliably distinguish CKD from non-CKD patients using routine laboratory data. This performance was stable across different feature selection strategies.
Effective Stage Classification
85% Stage Classification Accuracy (MLP + SelectKBest)For confirmed CKD cases, the system achieved up to 85% accuracy and 86% F1-score in stage classification (stages 3-5). AdaBoost with RFECV and MLP with SelectKBest demonstrated the strongest staging performance.

Final Output (Diagnosis/Risk)
| Model | Feature Selection | Binary Accuracy | Stage Accuracy | Runtime |
|---|---|---|---|---|
| Random Forest | All features | 0.96 | 0.77 | 24s |
| Random Forest | RFE | 0.97 | 0.69 | 54s |
| XGBoost | All features | 0.96 | 0.81 | 5s |
| XGBoost | RFE | 0.97 | 0.79 | 51s |
| MLP | All features | 0.94 | 0.85 | 44s |
| MLP | SelectKBest | 0.97 | 0.85 | 8s |
Feature selection significantly impacted computational efficiency and predictive performance, especially for the MLP classifier, where RFE reduced runtime from 44s to 8s while increasing accuracy from 94% to 97%. The impact varied by model and task.
Explainability and Risk Assessment for Early Intervention
Problem: Traditional CKD detection often relies on specialized biomarkers not routinely available, leading to late diagnosis for asymptomatic patients.
Solution: The framework integrates SHAP-based explanations and a continuous risk scoring mechanism. For non-CKD patients, a risk score (0-100) is generated based on proximity to CKD patterns, highlighting contributing laboratory features.
Outcome: This enables early identification of individuals at elevated risk, guiding targeted investigations like UACR testing or specialist referral without triggering formal CKD diagnosis, thus supporting preventive nephrology and reducing unnecessary clinical burden.
Explainable AI (XAI) Integration
SHAP Framework for Model InterpretabilitySHAP (SHapley Additive exPlaNations) is explicitly integrated to quantify the contribution of each laboratory feature to CKD risk. This provides both global (model-level) and local (patient-level) explanations, making the 'black-box' predictions transparent and clinically actionable. This enhances trust and understanding.
| Evaluation | K | Accuracy | AUC |
|---|---|---|---|
| Hold-out (70/15/15) | 8 | 0.983 | 1.000 |
| 5-Fold CV (mean ± std) | 8 | 0.987 ± 0.009 | 0.999 ± 0.000 |
The binary classification component was externally validated on the UCI CKD dataset, achieving strong and stable performance (0.987 accuracy, 0.999 AUC). This demonstrates the framework's generalizability beyond the Saudi-specific dataset.
