Architecture for Personal Health Record and its Trial Implementation

Abstract

　Because medical records are stored in each medical facility, even records about one disease of one patient are fragmented. To solve this problem, it is desirable to build a Personal Health Record (PHR). PHR requires a powerful center system on the cloud, which will be a cost burden. If a private sector run this business, designing of its business model becomes a key issue. We have considered an architecture of PHR centered on a medical information bank, where individuals entrust their personal medical data to the medical information bank that promotes data usage. We classified the data usage into medical use (primary use), non-medical health service use, and secondary use for research. We proposed a business model in which the medical information bank receive payment from beneficiaries depending of the type of the data usage. We tried the PHR service for obstetric patients at Osaka University Hospital. This service was well received by the patients. Based on this experience, we aim to develop PHR project.
