Results of Demonstration Experiment on Semi-Automatic Generation of Medical Documents, Commencement of "Discharge Summary" Semi-Automatic Generation Function Service (Planned), and Recruitment of Participating Medical Institutions for Demonstration Experiment
Based on the results of a demonstration experiment conducted by Homura Medical Corporation, NTT Precision Medicine, and PRiME-R, PRiME-R's developed "Discharge Summary" semi-automatic generation function will be offered as an optional service for NTT Precision Medicine's cloud-based electronic medical record "movacal.hospital" for small and medium-sized hospitals. This is expected to streamline medical document creation.

1. Results of the Demonstration Experiment
In the demonstration experiment, PRiME-R implemented a case report and medical history summary support system (hereinafter, "this system") that semi-automatically generates documents from medical texts using a large language model (LLM), which PRiME-R is developing as a research and development institution for SIP3 *3, into Movacal Hospital. We worked on the semi-automatic generation of discharge summaries using actual clinical information (present illness, past medical history, hospitalization course, etc.) at "Ouchi ni Kaerou. Hospital" and have been improving the accuracy of this system while incorporating evaluations and advice from doctors.
