Ubie, Inc., whose mission is to “guide people to appropriate medical care through technology,” announced that Ryukyu University Hospital has introduced “Ubie Generative AI.” The processing efficiency of registry registration work handled by CRCs, or clinical research coordinators, improved from 1.85 cases per hour to 4.31 cases per hour, a 2.33-fold increase.

The initiative comes as Japan’s physician work-style reform continues to accelerate task shifting in medical settings, while improving the working environment for all healthcare professionals remains an urgent issue. With the 2026 medical fee revision expected to further strengthen evaluation of medical DX and data utilization, healthcare providers are being asked to make fundamental improvements in operational efficiency to build sustainable care delivery systems. Ryukyu University Hospital is the only advanced treatment hospital in Okinawa Prefecture and the southernmost and westernmost university hospital in Japan. In January 2025, it relocated to the Nishifutenma Campus in Ginowan City and now plays a central role in Okinawa’s healthcare infrastructure. Like many medical institutions, the hospital faces heavy documentation burdens for physicians, nurses, and other medical staff. It had become difficult to secure enough time to prepare clinical records such as discharge summaries, creating a need for systems that can more reliably support medical quality. Against this backdrop, the hospital decided to adopt Ubie Generative AI, which offers a high degree of prompt customization and can be used flexibly by both beginners and experts. In CRC registry operations, staff previously had to review large volumes of electronic
