Beyond Traditional Diagnostics: Transforming Patient-Side Information into Predictive Insights with Knowledge Graphs and Prototypes
Predicting diseases from patient-side information like demographics and self-reported symptoms holds significant potential for enhancing patient awareness and healthcare efficiency. This research introduces KPI, a novel framework that integrates structured medical knowledge, clinically meaningful prototypes, and large language models (LLMs) to provide accurate and interpretable disease predictions. KPI addresses critical challenges of data imbalance and lack of interpretability in existing diagnostic models, delivering clinically valid explanations.
Executive Impact & Strategic Value
KPI offers a transformative approach to early disease detection, improving patient outcomes and optimizing healthcare resource allocation through enhanced accuracy and explainability.

The KPI Framework: Knowledge-Enhanced, Prototype-Aware, Interpretable
KPI integrates structured medical knowledge into a unified knowledge graph, constructs clinically meaningful disease prototypes, and uses contrastive learning for accurate predictions, especially for long-tailed diseases. It then leverages LLMs to generate patient-specific, medically relevant explanations, ensuring both accuracy and interpretability.

Inference Time (Full Test Set)
Efficient processing for real-world deployment, demonstrating practical viability alongside high accuracy for the entire test dataset.
Clinically Grounded and Patient-Aligned Explanations
KPI's interpretability feature generates patient-specific, medically relevant explanations. These justifications are not only accurate but also align closely with patient narratives, building trust and facilitating effective communication between patients and providers.
Real-World Clinical Explanation Case Study
Patient Narrative: "I have a stuffy nose, cough, and sore throat. I had a fever for the past two days. My throat is hoarse. It hurts so much when I cough. Now I feel like there is phlegm in my respiratory tract and I can't cough it out..."
KPI Predicted Disease: Pneumonia
KPI Explanation: "The patient's symptoms—fever, cough, sore throat, and phlegm—align with pneumonia, a lung infection. High attention score triples link pneumonia to respiratory infections and chronic lung diseases like COPD, supporting this diagnosis."
Impact: In contrast, other models either provided no explanation or an inaccurate diagnosis (e.g., Cold or congenital heart disease), highlighting KPI's ability to provide semantically reliable and clinically coherent reasoning.
