Innovative Semi-Automated Document Generation in Healthcare

The collaboration between Homura Medical Corporation, NTT Precision Medicine Inc., and PRiME-R has unveiled exciting developments in healthcare documentation. Starting from June 2025, a demonstration experiment has been conducted, showcasing a semi-automated generation function for discharge summaries using PRiME-R’s advanced capabilities in Large Language Model (LLM) technology. The announcement marks a significant step towards streamlining medical document creation in small to medium-sized hospitals with the introduction of NTT's cloud-based electronic medical record system, movacal.hospital.

Results of the Demonstration Experiment

During the demonstration experiment, the semi-automated discharge summary generation system implemented on movacal.hospital utilized real clinical data from Homura Medical's facilities. It integrated real-time feedback and evaluations from participating physicians to enhance the system's accuracy. Findings revealed that this innovative system substantially reduced the time required for healthcare professionals to create discharge summaries—some reported accomplishing this task in just one-third of the usual time. One physician noted, "I was able to complete the discharge summary in about a third of the time compared to traditional methods." This efficiency indicates a promising future for medical documentation practices.

The system continues to be actively used by healthcare staff at "Home Coming Hospital,'' who have expressed favorable opinions regarding its efficiency. The ability to minimize time spent on checking facts and retrieving records during a physician's absence significantly contributes to overall workflow improvement.

Launch of the Discharge Summary Function

Building on the success of the initial experiment, the semi-automated discharge summary function is slated for commercial launch in the first quarter of the 2026 fiscal year as an optional service within movacal.hospital. Medical institutions interested in this service will soon find additional information and pricing details on the movacal website. Those interested are encouraged to reach out for inquiries and registration.

User-Friendly Interface for Healthcare Professionals

Within the movacal.hospital interface, an AI summary button allows medical staff to quickly generate summaries. Upon activation, the AI analyzes clinical documentation and provides a concise summary, which can then be reviewed and fine-tuned by healthcare providers. This capability not only speeds up the documentation process, but also facilitates improved accuracy in medical records.

Expansion to Other Medical Documents

In addition to discharge summaries, there are plans to extend similar semi-automated generation capabilities to nursing summaries and medical information provision documents. This initiative aims to create an optimal working environment for not only physicians but also nurses and administrative staff by mitigating administrative burdens. Participation is sought from various medical institutions to generate comprehensive evidence that accounts for diverse formatting and procedural differences across hospitals.

Future Development Plans

Moving forward, Homura Medical, NTT Precision Medicine, and PRiME-R remain committed to incorporating clinical feedback and needs into continuous research and development efforts. The goal is to automate the generation of various medical documents, thereby alleviating the documentation workload on healthcare professionals and contributing to the broader reform of work practices in healthcare. This, in turn, will promote the advancement of medical services and improve operational efficiency.

In conclusion, the collaborative endeavor highlights the increasing role of technology in healthcare and sets a pathway for innovations that can lead to superior patient care and enhanced operational efficiencies. The industry peers and stakeholders are invited to observe and engage with this transformative project, which promises to change the landscape of medical documentation in the near future.
