Blood services - which are managed in Japan by the Japanese Red Cross Society - are a key part of the national medical infrastructure. However, doctors' perception of blood services is often limited to a superficial understanding. Although the role of medical check-up doctors in securing safe and high-quality blood is important, there is a continuing shortage of doctors dedicated to blood centers and medical check-up doctors in terms of actual numbers and knowledge of blood services. The "Nara Regimen" consists of two protocols, namely "blood transfusion education and practical training (14 hours) " at the Blood Transfusion Division of the Nara Medical University Hospital and "practical training (3 hours), including blood donor experience" at the Nara Red Cross Blood Center, as pre-graduate education for medical students of Nara Medical University; and "On-the-Job Training for blood donation work" for 1 week at the Nara Red Cross Blood Center as post-graduate education for clinical residents. In this study, we examined the results of these programs, focusing on the number of participating medical check-up doctors, and clarified the contribution of doctors who completed the "Nara Regimen" to blood donation medical check-ups. Although training for medical students and clinical residents is a substantial burden on blood centers, the "Nara Regimen" of active and continuous education and training will increase doctors' awareness of blood services, and function effectively and efficiently to train and secure medical check-up doctors who will contribute to blood services.
