What We Know About the Role of Large Language Models for Medical Synthetic Dataset Generation
This systematic review evaluates the use of Large Language Models (LLMs) for generating structured medical text, addressing data scarcity and privacy in clinical NLP. It examines techniques like RAG, structured fine-tuning, and domain adaptation. While LLM-generated text improves fluency, challenges like hallucinations and factual inconsistencies persist. Structured models (SOAP, Calgary-Cambridge) enhance coherence but don't prevent all errors. Hybrid approaches combining retrieval grounding and fine-tuning improve accuracy. Conventional metrics are insufficient, needing domain-specific benchmarks. Privacy strategies (differential privacy, PHI de-identification) support compliance but may reduce quality. Findings are crucial for AI-powered scribe systems, enhancing transcription accuracy and documentation reliability through structured synthetic datasets, advocating for a balance of structure, factual control, and privacy.

| Challenge Addressed | Issue in LLM-Generated Synthetic Text | Solution via Structured Medical Frameworks |
|---|---|---|
| Faithfulness and Clinical Relevance | LLM-generated dialogues often lack structured clinical progression and deviate from real-world medical interactions. | Training LLMs with structured models (e.g., Calgary-Cambridge, SOAP) ensures logical, medical questioning and progression, improving clinical training and research dataset usability. |
| Hallucinations in Clinical Conversations | LLMs frequently introduce fabricated symptoms, test results, or diagnoses that were not present in the input data. Lack of structured constraints leads to unpredictable factual inconsistencies. | Embedding structured consultation formats constrains LLM outputs to follow expected medical interactions, reducing the risk of hallucinated symptoms and fabricated patient histories. |
| Dataset Generalization | Synthetic medical text lacks adaptability across clinical settings, specialties, and languages. Models trained on domain-specific, unstructured synthetic data struggle with real-world clinical tasks. | Structured LLM fine-tuning with consultation frameworks (SOAP, SBAR, and Calgary-Cambridge) improves dataset standardization and enhances cross-domain generalization for multiple medical specialties. |
AI-Powered Medical Scribe Systems
The research highlights the significant potential of LLM-generated synthetic data in advancing AI-powered medical scribe systems. By automating clinical documentation through ASR and NLP, these systems can leverage high-fidelity, privacy-preserving synthetic conversations to bridge data scarcity gaps. This approach enhances transcription accuracy, improves domain adaptation, and supports multilingual processing. Structured medical frameworks, combined with hybrid evaluation techniques like retrieval augmentation and knowledge-infused prompting, are crucial to ensure factual consistency and clinical reliability, making these systems viable for real-world deployment in healthcare.
Key Takeaways:
- Leverages LLMs for synthetic clinical dialogue generation.
- Improves ASR transcription robustness and NLP summarization.
- Addresses data scarcity and ensures patient privacy.
- Requires integration of structured medical frameworks (SOAP, SBAR) for coherence.
- Essential for multilingual adaptability in healthcare systems.
