Various projects which manage personal information using SBTs are emerging in various industries.
  • SUSMED (Case study in Japan)
SUSMED is a company that develops a medical-support application for patients with insomnia, breast cancer, kidney disease, and such. SUSMED provides a "SUSMED system" to advance efficient drug development. Clinical trials, an essential part of drug development, carry an enormous cost, one of the factors causing the high price of drugs. For this reason, SUSMED uses its own-developed blockchain technology to ensure the reliability of clinical trial data, which will reduce the workforce and expenses which have been previously allocated to clinical trials.
  • Estonia (Case study outside of Japan)
The Republic of Estonia has been working on its own digital society. In Estonia, it is mandatory for citizens to obtain a citizen ID card. Doctors need a patient’s citizen ID card to access patient’s medical information. Estonia has developed a system which records log data on who has accessed the citizen ID cards. If any issues arise, the issues can be traced back to past data.
  • MediLedger Network (USA)
Bayer and Pfizer are two of the large companies that participate in MediLedger Network, a project founded in the U.S. MediLedger Network manages a pharmaceutical supply chain using a blockchain and provides the supply chain as a service to maintain rules and order in the industry.
The above three project models are what the CARE project aims for now. Although SUSMED is a private company, SUSMED contributes to, beyond a typical role as a private company, streamlining the medical industry by using blockchain for medical data management. SUSMED also cooperates with various research institutes and universities and conducts demonstration experiments on SUSMED’s services with them.
Estonia is often viewed as one of the ideal countries. In Estonia, each citizen's information is managed properly, and each citizen's health information and their IDs are associated with each other. By associating the information with IDs, Estonia has achieved efficient systems on the medical institution side and the patient side. Further, since the medical histories of patients are recorded, it helps medical institutions recognize patient's conditions accurately and helps both parties choose a proper treatment. MediLedger Network is a highly scalable project in which some existing large pharmaceutical firms have participated. In terms of supply chain management, MediLedger Network aims for efficiency and security improvement of the supply chain using blockchain technology.
The CARE project will proceed with efficient project expansion and realize the decentralized society (DeSoc) learning from the above project models.
