Intelligent Simulated Patient System for Gastroenterology Education
Sponsor: The First Affiliated Hospital of Zhejiang Chinese Medical University
Summary
This randomized controlled trial evaluated a large language model-based Intelligent Simulated Patient System (ISPS) for gastroenterology history-taking education. The system integrates retrieval-augmented generation (RAG), electronic health record-based knowledge retrieval, virtual patient interaction, and automated scoring. Ninety medical students were randomly assigned to conventional training or ISPS-assisted training. Primary outcomes included history-taking completeness and diagnostic accuracy. Secondary outcomes included empathy performance and technology acceptance.

Interventions
Intelligent Simulated Patient System (ISPS)
Participants received four weeks of self-directed training using the Intelligent Simulated Patient System (ISPS), a large language model-based educational platform developed for gastroenterology history-taking training. The system integrates retrieval-augmented generation (RAG), de-identified electronic health records, disease-specific knowledge retrieval, virtual patient simulation, automated history-taking assessment, and individualized feedback. Participants independently selected clinical cases, conducted repeated history-taking interviews with virtual patients, received automated evaluations of history-taking completeness, and reviewed personalized feedback throughout the intervention period.
Conventional Clinical Teaching
Participants received conventional clinical education for four weeks, including bedside teaching, case-based learning, paper-based medical record review, and faculty-guided clinical discussions according to the standard curriculum.
