Abstract
For the sharing and exchange of information between medical clinics, the clinical document has to be built on a standardized protocol such as a HL7-CDA. But it is difficult to exchange information between medical clinics because clinical document such as electronic medical record that include text and image, have different structure of document and type of expression. In this paper, we propose the electronic medical record system based on HL7-CDA that can share and exchange clinical information between medical institute. For this purpose, we have to design the schema of the clinical document architecture after we select the essential items of medical record and define templates. The proposed system can minimize integrating process and save parsing time when clinical information exchange and refer, by converting electronic medical record to base64 encoding scheme and integrate it in a XML document.
