Start of Joint Research Using Medical Big Data for Treating Broken Bones
Japan System Techniques Co., Ltd. (JAST) has started a joint research project with assistant professor Hiroyuki Okadaof the Clinical Biotechnology Department of the Center for Disease Biology and Integrative Medicine of The Universityof Tokyo Graduate School of Medicine. The project concerns the use of medical big data for the diagnosis and treatmentof broken bones.
■ The Joint Research Program
As Japan’s population ages, the number of broken bones due to osteoporosis, including breaks of the femur, is increasing
steadily. Furthermore, effective treatments are needed for repeated secondary bone fractures and breaks that follow theinitial break due to osteoporosis. However, there is currently an inadequate level of osteoporosis treatments that areessential for preventing secondary fractures and breaks. In Japan, insurance payments for preventing secondary
fractures and breaks have finally been raised, but more actions are needed to increase the use of these preventive
measures.
Osteoporosis requires treatments involving many fields of medicine, including orthopedics, geriatrics, endocrinology,gynecology and others. Insufficient or improper treatments can cause fractures and breaks. Patients require care thatencompasses many fields of medicine but involves mainly orthopedics when there is a fracture or break. Many olderpeople with a broken bone need treatments for internal diseases accompanying the break. In Europe and North America,these individuals often receive treatments by a team of healthcare professionals covering many specialties and led by aphysician specializing in geriatrics. In Japan, most older people with broken bones are treated only by an orthopedic
physician. As a result, it is often difficult to achieve a sufficient exchange of information between the physician treating
osteoporosis and the physician treating the fracture or break.
Ending this problem will require collecting evidence for both increasing theuse of osteoporosis treatments and using many medical specialties for thetreatment of fractures and breaks. To accomplish this, the separate
knowledge and data of osteoporosis physicians and orthopedic physiciansmust be integrated. The effects of osteoporosis treatments on the progressof the treatment of fractures and breaks need to be identified. In addition,
patients in Japan should be managed just as they are in Europe and North
America in order to facilitate the seamless teamwork of physicians in many
fields of medicine.

invoice data (see note 1) of approximately 8 million people. By working
with Dr. Okada, this information will be used to determine how osteoporosis treatments influence the treatment of femur
breaks. Another goal is to devise effective ways to prevent secondary fractures and breaks. This project also has theobjective of using the results of this research to help improve the management of osteoporosis worldwide and heighten
Japan’s position as a leader in the field of medicine.

When an individual receives a medical treatment covered by insurance, the healthcare institution sends an invoice listing
the procedures and amounts due to the insurance company or organization. For medical and dental care, an invoice listing
the procedures and amounts due is sent. For pharmacies, an invoice listing the drugs supplied and amounts due is sent.
For nurses visiting individuals at home, an invoice listing home nursing care services and amounts due is sent. One
invoice for each patient and individual healthcare institution is prepared every month. Invoices contain information about
the reasons that individuals received medical care, the cost of the care and other items. JAST converts this information
into a database for subsequent utilization.
