Abstract
The systems of Medical Information Exchange among hospitals have widely been important issues in healthcare industry due to the non-interoperability of medical information in Korea. In this paper, to be able to consider more effective ways of sharing patients' medical information, we developed a new Medical Information Exchange System (MIES) based on Registry Server Model which the system enables us to interoperate different types of data made by various different systems. To develop MIES based on Registry Server Model, we deal with the standardized data transfer methods and the terminologies suggested by Center for Interoperable EHR (Electronic Healthcare Record) of Korea to guarantee the interoperability of each participating system in each hospital. By applying the EHR standard to the proposed MIES, we assure that a patient's medical information can be effectively exchanged under the different system environment. To ensure the information security, reference is made to the security guidelines suggested by the Center for Interoperable EHR of Korea. This study aimed at essential security systems for implementation of online services, such as encryption in the communication section, server security, database security, protection against web attacks, contents security and network security. The proposed MIES designed as centralized the Registry Server Model independently to guarantee the security for the sharing patient's medical information to minimize.
