Implementation of Medical Information Exchange System Based on EHR Standard / 대한의료정보학회지

OBJECTIVES: To develop effective ways of sharing patients' medical information, we developed a new medical information exchange system (MIES) based on a registry server, which enabled us to exchange different types of data generated by various systems. METHODS: To assure that patient's medical information can be effectively exchanged under different system environments, we adopted the standardized data transfer methods and terminologies suggested by the Center for Interoperable Electronic Healthcare Record (CIEHR) of Korea in order to guarantee interoperability. Regarding information security, MIES followed the security guidelines suggested by the CIEHR of Korea. This study aimed to develop essential security systems for the implementation of online services, such as encryption of communication, server security, database security, protection against hacking, contents, and network security. RESULTS: The registry server managed information exchange as well as the registration information of the clinical document architecture (CDA) documents, and the CDA Transfer Server was used to locate and transmit the proper CDA document from the relevant repository. The CDA viewer showed the CDA documents via connection with the information systems of related hospitals. CONCLUSIONS: This research chooses transfer items and defines document standards that follow CDA standards, such that exchange of CDA documents between different systems became possible through ebXML. The proposed MIES was designed as an independent central registry server model in order to guarantee the essential security of patients' medical information.

Development of PDA Application Model for Health Promotion Center / 대한의료정보학회지

Health promotion center is an area that hospitals promote and operate with priority for the early detection and prevention of disease. The quality of medical service needs to be improved by providing a quick and customized service to the patients who use the center. In the past, the examiners or hall managers took charge of the guidance and management of the patients in order, and the patients suffered from the disorder and discomfort while they are called and identified by name. In this paper, we realized automated health promotion system using PDA operation system to provide services comfortable for both patients and examiners. A comfortable and personalized system has been developed, where patients are provided with personalized guidance for the examination labs instead of being called by name and history of medical examination through the mobile terminal,
