Health InformaticsMedicine and Medical Science

M.D., Ph.D. Professor Takeo Nakayama

In today’s society, the impact of health-related information on human behaviors and health can be just as profound as, or in some cases, more profound than, the impact of physical environment on human health. This field of study explores how information can contribute to improving people’s health behavior/health-care-seeking behavior, and decision-making in community health. The main topics to be covered are: Evidence-based healthcare (EBHC); decision analysis, health literacy & communication; epidemiologic research including genome approach, quantitative and qualitative assessment of health-related information; e-Health; and information ethics.

Research and Education


Health informatics has potential applications for the creation, communication and use of information, and the discipline is being expanded as nap practical applied science in search of solution. Creation: epidemiological researches (including genome-approach), information ethics, and appraising scientific information. Communication: systematic reviews, clinical guidelines, creating databases, developing tools for decision-making support, and health communication Use: health literacy, and shared-decision making
