JAST Starts Research Project Using Medical Big Data with Tokyo University
Japan System Techniques Co., Ltd. (JAST) has started a joint research project with the University ofTokyo Department of Healthcare Economics and Health Policy, which is part of the Graduate School ofMedicine. Conducted with a research group led by Project Professor Tomoyuki Takura, the project uses
medical big data accumulated by JAST that covers approximately one million people.
1. Summary
Since August 2010, JAST has been selling an automated electronic health insurance claims checking andanalysis software called JMICS. JAST used its extensive and broad expertise involving ICT to create thisinnovative product for speedily and automatically processing the monthly invoices that health insurers
receive from medical institutions. In April 2013, JAST started a big data business for health insurers.
Centered on JMICS, the big data business has a larger range of solutions by incorporating health check-upinformation and other data from external sources, performing analysis and notification tasks, andproviding other services.
With the participation of Professor Takura, this joint project will use the data covering about one million
people in invoices submitted by medical institutions to health insurers. This information has been
accumulated by JAST’s JMICS health insurance claims checking and analysis software. The objective isto determine the causes for growth in medical expenses for the purposes of achieving a proper level ofthese expenses and helping people stay healthy. All information that identifies specific individuals will beremoved from the medical billing data that is used for this project. Furthermore, health insurers (healthinsurance associations and local governments) have given their permission to use the insurance claim
billing information.
The first stage of this project will be a study of individuals receiving dialysis. The study will determine
how a government program to reduce patients’ payments for dialysis and interventions to improve life
styles influence the behavior of patients and the composition of medical care. To accomplish this, theresearch will perform analysis by using behavioral economics. In addition, useful information gained
from this research may be used by JAST for the development of systems that utilize these new insights.
By supplying these systems to health insurers and companies in the health care sector, JAST plans to help
achieve the proper level of medical expenses for health insurers for all types of health insurance.
Medibrain Corporation (Head Office: Chuo-ku, Osaka; President: Takahiro Naka), a company that uses
JMICS, will also cooperate with this joint research project by supplying data and assisting in other ways.
