A common electronic data interchange standard become more important. After thirty years development experience, HL7 has become a mature and conformance standard. On one hand, using HL7 as the primary exchanging standard for the medical information system support by Department of Health, on the other hand, it can reduce the cost and increase the public welfare. Laboratory information produce from medical instrument, the character of objectivity makes hospital rise the willing of exchanging and sharing. Hence, the requirement of the HL7 integrated system that focused on the laboratory information system is getting higher. This thesis researched the heterogeneous integrated methodology and commercialized tool kit about introducing HL7. We explored the HL7 message structure, data structure of laboratory information system, the hierarchical relationship, schema-mapping and integration method, and the integration mechanism about coding system. Then we proposed a mechanism which using visualization method to setup and convert the schema. The mechanism didn’t need to add or modify the programming code while introducing HL7. This thesis proposed a simpler method compare to the commercialized integration tools. The method required lower know-how about HL7 from the configuring user, it also speed up the implementation cycle, lower the entry barrier of introducing HL7, and reduce the cost while introducing HL7 standard to the laboratory information system. In order to evaluate the methodology, this research implemented an HL7-based prototypal standardization system focused on laboratory information system. We also evaluated the performance about the effect of the prototypal system, the result shown the extra effective delaying time per transaction were less than 20%, the total effective delaying time were only 6.21%. Hence, the effect to the current system from Unified Approach for Integrating Laboratory Information System using HL7 Standards is very limit and the system is valuable and practical.
