Automatic RIM (Reference Information Model) Wrapper for LEX: Lifelong Electronic Health Record Based on XML

INTRODUCTION The Lifelong EHR based on XML (LEX) project is a pilot project currently under development, whose ultimate goal is to integrate patient data in the Central Clinical Database (CCDB) which can be shared with heterogeneous HIS. The following paper describes the design and implementation of a software framework that could be used to construct an HL7 message server for the sharing of patient medical information. HL7 is a standard for electronic data exchange in healthcare environments. However, applying HL7 to the existing HIS requires enormous work because almost all Korean hospitals have their own HIS and their own unique combination of interfaces and data structures. We present solution that requires minimum changes to the existing HIS and is independent of the specific client user application. It is to add an interface engine called HL7 message server to the existing environment.
