LLaMPS、安全な大規模言語モデルアプリケーションの開発と実装：患者安全ワークフローの自動化

Despite significant advancements in Generative Artificial Intelligence (GenAI), practical adoption in healthcare, particularly patient safety, remains challenging due to concerns regarding data privacy, model transparency, clinical relevance and user engagement. We present LLaMPS (Large Language Model for Patient Safety), a locally deployed GenAI platform designed to enhance patient safety event management and reporting. LLaMPS integrates automated incident classification, harm-level prediction, intelligent search, and an interactive chatbot. The system employs a Retrieval-Augmented Generation (RAG) approach, leveraging secure, institutionally hosted large language models (LLMs) and a vector database to ensure data privacy and regulatory compliance. Developed iteratively with direct input from clinicians and patient safety experts, LLaMPS demonstrates high classification accuracy and improved user satisfaction, underscoring the potential of locally controlled AI solutions to enhance patient safety workflows.
