MERA: Medical Electronic Records Assistant
MERA is a RAG-based AI system that addresses challenges in electronic health records (EHRs) by integrating domain-specific retrieval with LLMs to provide robust question answering, similarity search, and report summarization. It aims to overcome limitations of conventional LLMs like hallucinations and outdated knowledge in healthcare.Validated on both synthetic and real-world EHRs (MIMIC-IV-Note), MERA demonstrates high accuracy (correctness: 0.91, relevance: 0.98, groundedness: 0.89, retrieval relevance: 0.92) in medical question answering, strong summarization (ROUGE-1 F1-score: 0.70, Jaccard similarity: 0.73), and effective similarity search (METEOR: 0.7–1.0). The system supports differential diagnosis and personalized treatment by generating concise, contextually relevant, and explainable insights, reducing clinician workload and enhancing decision-making. MERA is the first system to unify these functionalities within a RAG-based framework for healthcare.

METEOR Score for Similarity Search across diagnoses
Impact on Clinical Decision Support
A clinician uses MERA to find patients with cases similar to a new complex patient. MERA quickly retrieves top K similar cases, summarizes their diagnostic paths and treatment outcomes, and highlights differences. This allows the clinician to identify effective interventions and potential complications, leading to a personalized treatment plan and reducing diagnostic time by 30%.
