OpenAI's ChatGPT is gaining traction not only for its ability to generate natural text but also for its advanced natural language processing. It is expected to be utilized in the medical industry as well. In the Medical DX Reiwa Vision 2030, the government proposes the realization of effective, efficient and high-quality medical care delivery. Reforming the working style of medical professionals through medical DX has been a long awaited process, and we have started to study work in medical practice where generative AI can be used to solve social problems. Specifically, we have proposed a "business support service for medical professionals" that combines an electronic medical record system and a generative AI system to medical sites, and are continuously working to solve problems while evaluating PoC/efficiency improvement and business improvement at the sites. In the future, it seems that the scene which can utilize the generation system AI in accordance with the change of the medical field will expand. Looking forward to a future in which everyone can receive safe and secure medical care through the government's commitment to providing high-quality medical care, we will consider how generative AI can be used by medical institutions from the perspective of vendors.
