Characteristics of the section:

     Our primary research focus is the diagnostic strategy, and we are publishing innovative and unique theoretical concepts and actual practice cases in the leading medical journals across the world. We are also studying the implementation of novel technology in medicine, such as telemedicine and artificial intelligence. With the integration of state-of-the-art theories and technology, our future goal is to provide a new framework for better clinical reasoning and reduce diagnostic errors in medical practices.
     Medical and clinical education is another essential role of our department. The characteristic of our department is that we have a program dedicated to physicians above fellows or attending levels, who are willing to develop a new department or division of general medicine or to be a leader of the field of general medicine/hospital medicine (OSLER program). In addition, we started the doctoral program in 2018 for physicians who want to proceed with their academic careers.
