Abstract
In 2004, we introduced the electronic medical record system that included the cutting-edge applications. However, there existed two major problems to solve in replacing the system in 2009; one was an absolute improvement of the system performance, the other was to offer the chronological and intuitive image of a patient's medical information. The former has been achieved by introducing the 64 bit Linux servers, and two-layer client/server connection, along with high specification PC clients. The latter has been achieved by developing the new applications which are designated as the Medical Viewer and Medical Explorer. We have also developed and introduced the cutting-edge tools (e.g. the prescription knowledge tool, the USB memory authentication and management system). When considering the future prospects, greater efforts should be made to develop the cutting-edge tools for supporting clinical decision making and also to provide precise data for the administrative management.
