PHR system using blockchain technology

Abstract

PHR is easy to check patients’ health condition, which is suitable for the customized medical service. However, the EMR systems were made of different type in each medical institute, thereby being difficult to integrate the information into PHR. A Cloud is an appropriate alternative because it has easy environment where the integrated PHR is easily built and processed while keeping the system under various EMR systems. The concept of the current medical paradigm has been changing from treatment to management. For the management, it is important to know current health condition, but the existing diseases and their treatment processes. The environment of medical information is shifting from recording and to saving into PHR which is an integrated record of EMR information and subsidiary patients’ health information. PHR is very easy to check patients’ health condition, which is suitable for the customized medical service. This study provided how to apply blockchain technology to the medical field and utilize it for PHR applications. For these applications, it suggested an architecture for gateway application of healthcare date to control and share PHR data more easily and securely.
