A Multi-Agent AI Framework for Unified Healthcare Assistance Using Retrieval Augmented Generation

  • Abstract:
  • This paper proposes a centralized AI system for healthcare assistance that uses a manager agent to orchestrate three specialized agents: a Diagnostics Agent, a Search Agent, and a Hospital Operations Agent. The Diagnostics Agent employs a fine-tuned clinical BERT model (BioClinicalBERT) combined with Retrieval-Augmented Generation (RAG) over a ChromaDB vector store, enriched by results from a Search Agent. The Search Agent integrates Google Custom Search on trusted medical sites and an internal document RAG system. The Hospital Operations Agent uses Python-based analytics and visualization tools to present patient and resource data, aiding junior doctors with on-demand preliminary diagnostics. This modular, RAG- driven approach is compared against monolithic Large Language Models (LLMs) and fine-tuned models, demonstrating improved efficiency, accuracy, and cost-effectiveness. The orchestration of specialized agents not only parallelizes complex tasks but also mitigates hallucinations through domain-focused retrieval. Comparative tables and scenarios highlight these benefits, un- derscoring how modular RAG architectures can adapt rapidly to new medical information without costly retraining.
