Research and implementation of Electronic Medical Records Editing System based on CDA

摘要

It is difficult to exchange information between heterogeneous Hospital Information Systems (HIS). It becomes the obstacle of regional medical system establishment. The coming forth of HL7 (Health Level 7) CDA (Clinical Document Architecture) standard provides the technical basic conditions. This paper describes CDA standards and CDA document structure. Through a complete analysis of Electronic Medical Record (EMR), the model of Electronic Medical Records Editing Subsystem is given. Based on this model, functional modules of Electronic Medical Records Editing Subsystem are designed and implemented. Through Electronic Medical Records Editing Subsystem, clinical documents can effectively produce, parse, validate and view. It provides a technical support for exchanges of medical and health information.
