| Summary: | 碩士 === 國立成功大學 === 工程科學系 === 88 === With the rapid growth of the Internet, hospitals gradually exchange data through the Internet to improve the efficiency of data processing. In essence, the environment of a referral is distributed, and there are huge volumes of data having to be exchanged between referring and referred-to providers. If we could take advantage of information technologies to exchange referral information, the integration of the clinical or demographic data in different hospitals may be more easily, and then, the unnecessary examinations and the waste of medical resources could be reduced.
In the process of medical data exchange, if there are not any standards to follow, hospitals have to customize their exchange interfaces so that the complexity of exchange may increase. Therefore, the development of medical data exchange standards is urgent and necessary. In order to avoid the situation described above, the HL/7 (Health Level / Seven) standard has been developed. Its primary goal is to provide standards for medical data exchange, to simplify custom interfaces in programming, and to share the medical information.
In this study, we design and implement an electronic referral system based on the messages and trigger events of the HL/7 standard. Moreover, we not only propose the architecture of implementing the HL/7 standard but also model the referral system by Unified Modeling Language (UML). Finally, this study will be recommended as a reference of implementing the HL/7 standard for the National Cheng-Kung University Hospital (NCKUH) or other cooperative hospitals.
