Niigata University of Health and Welfare

Major in Health Informatics and Business Administration
Field of Health Informatics and Business Administration


The Major in Health Informatics and Business Administration opened in April 2014. In the Field of Health Informatics and Business Administration, we train specialists for a new era of medical services in which health information and hospital management require highly specialized knowledge and skills. The purpose of this field is to foster health information managers who can not only help determine critical paths which delay the improvement of patient satisfaction and quality and efficiency of hospital management, but also assess possible shortcuts for better services.


Coping with advancement of research, medical practice and education
While striving for an advancement in health science research and education, we will train educators, researchers as well as highly specialized personnel in clinical settings.
In addition, we developed external education with a system composed of CISCO and two cloud systems (Dropbox and Google drive) in 2017. This system is for advanced research meetings and is expected to be effectively utilized for research and education externally.
Coping with systematic and organizational prevention of medical accidents/malpractices
Systematic and structural determination of the causes of medical accidents (malpractices) and their preventive measures has become urgent matter in recent years. Experts in the health information management and hospital management are expected to be key persons in constructing a medical safety system in the hospital. Main components of clinical governance are: evidence-based medicine, clinical guideline (e.g. critical path), clinical audit, clinical indicators, and patient safety
Coping with medical insurance system
Since the introduction of a new medical insurance system of DPC (Diagnosis Procedure Combination) in 2003, the work of Health Information Manager (HIM) has become essential for the smooth operation of the system. Thus, mastering the necessary knowledge and skills is highly required and this can be achieved through a better understanding of ICD-10 by WHO, knowledge of medical information technology, the medical insurance system, compliance issues for healthcare providers, and advanced skills of medical clerk for supporting doctors’ daily examination and research activities.
Coping with advanced and increased hospital administrative work in the aging society
As doctors’ administrative work advances and increases, we are more required to foster specialists in information technology and improve their systematic skills in order to maintain or, better yet, improve the quality of medical services and guarantee patient’s safety.
Coping with changing social conditions and system reforms
We aim to foster professionals with technical and comprehensive knowledge and skills required across all the services of health and welfare. We expect our students to contribute to the development and maintenance of the welfare systems of local communities.
