A large-language model-driven approach to chronic disease follow-up
This research proposes a novel LLM-driven approach to chronic disease follow-up, addressing limitations of traditional methods such as resource inefficiency and poor personalization. It integrates fine-tuned LLMs with Graph-based Retrieval Augmented Generation (GraphRAG) for accurate data utilization and real-time knowledge updates. The system emphasizes personalized patient interaction and semantic similarity for enhanced compliance and efficiency. While noting the current lack of comprehensive structured data, it sets a framework for future refinements in vertical healthcare applications.

LLM Training & Architecture
This section details the fine-tuning of pre-trained LLMs using chronic disease-specific datasets, specifically mentioning the selection of Yi-1.5-9B and the application of LoRA for efficient parameter fine-tuning. It outlines the data collection, preprocessing, and the LLaMA-Factory framework used for training.
GraphRAG Integration
This section explains how Graph-based Retrieval Augmented Generation (GraphRAG) is integrated to enhance data retrieval and response accuracy. It uses knowledge graphs built from patient history, cases, symptoms, and treatment guidelines, like those for COPD, to overcome LLM knowledge blind spots and facilitate contextually relevant information.
System Design & Workflow
This section outlines the overall process design for the LLM-driven follow-up method. It describes how the system initiates follow-up, queries patient data, uses semantic similarity and GraphRAG for relevant information, generates personalized questions via Prompt Engineering, and stores interaction records.

COPD Management with GraphRAG
The study highlights COPD as a key example. By integrating GraphRAG with clinical guidelines and patient data, the system extracts entities like disease names, symptoms, and treatments. This allows for more relevant and contextually understood retrieval of patient information and authoritative guidelines, significantly improving the accuracy and credibility of generated content. For instance, when a patient asks about daily activities, the system can provide tailored advice based on their history and general guidelines, such as 'avoid overexertion' and 'incorporate pursed-lip breathing'.
Projected ROI: Enhanced Patient Management

Implementation Roadmap
A phased approach ensures seamless integration and maximum impact.
Phase 1: Data Acquisition & LLM Fine-tuning
Collect and preprocess chronic disease datasets. Fine-tune chosen LLM (e.g., Yi-1.5-9B with LoRA) for domain-specific tasks. Establish initial model performance benchmarks.
Phase 2: Knowledge Graph & GraphRAG Development
Construct knowledge graphs from clinical guidelines (e.g., COPD guidelines) and patient data. Integrate GraphRAG framework for structured and unstructured data retrieval.
Phase 3: System Integration & Pilot Deployment
Integrate the LLM and GraphRAG components into the follow-up system. Develop personalized interaction modules and real-time knowledge update mechanisms. Conduct pilot testing with a small patient group.
Phase 4: Optimization & Scalability
Continuously refine the knowledge graph and LLM performance based on feedback. Expand to broader patient populations and integrate with existing EMR/EHR systems for full operational scalability.
