Osaka Metropolitan University received a time-limited accreditation decision in the first medical education programs evaluation review in 2017. Based on the advice for improvement, the university resubmitted an improvement version for evaluation and underwent an additional review in 2020, as a result of which the improvement was evaluated and the review was approved. However, one of the issues that still required improvement after the additional review was the structure, organization, and duration of the educational program. First, it was desirable to devise a curriculum that would further promote horizontal and vertical integration of basic and clinical medicine, integrate lecture schedules, and reconsider the balance between the various fields of study. It was also desirable to further promote horizontal integration of related scientific and academic disciplines and issues, as well as seamless vertical integration of basic medicine, behavioral science, and social medicine with clinical medicine. This presentation will introduce the efforts, including its current and challenges, by Osaka Metropolitan University.
