在現今健保支付制度變革及醫療環境之變遷下，如何提供民眾滿意之健康照護服務，又合乎成本面之考量，是目前醫療機構體系最重要的課題之一。跨院際的醫療資訊交換越來越受到重視，在健保制度環境下，除了避免醫療資源的重覆浪費，並可藉由網路傳遞使得醫療服務人員能即時獲得跨院所之完整醫療資訊，對病患的病情給予更精確的診斷與及時且適當的處置，其中電子病歷、財務申報、醫療資材管控、傳染病通報等皆為可行之應用，由此可見醫療資訊交換重要性。另一方面，在醫療資訊交換的一個重要關鍵在於有效整合醫院內部或是院際之間彼此異質環境下的資料，因此統一的醫療資訊交換標準有其必要性，HL7標準便順應此一潮流所制定出來。
　　藉由分散式物件技術的利用，醫療資訊交換有較高的延展能力，透過SOAP使HTTP通訊協定於分散式架構中更具效能，並結合XML(eXtensible Markup Language)來描述HL7的文法與語意、定義標籤，擴展醫療資訊交換能力。而SOAP與XML技術的導入，便可有效彌補舊有醫療資訊環境封閉性架構的限制與不足。
　　本研究之目的在於如何將跨醫療院所資訊相互交換傳遞，運用低成本並具完整性的醫療資訊交換模式，發展出以HL7/XML為基礎的電子病歷傳輸介面設計，並整合成XML Web Services為核心的醫療資訊交換服務元件，讓使用者/用戶端可以經由公用性醫療資訊交換服務元件迅速地編碼與解譯，以提昇位元傳輸在及時性和完整性上的價值，並建構一電子病歷交換平台，驗證傳輸介面可行性。最後，以實證探討來對所提之雛型進行驗證，探討此系統之優劣。

　Though many hospital information systems have been implemented in the past, the information sharing among different hospitals and different systems in the same hospital is still a difficult issue due to the isolated design of the information systems. This problem becomes obvious in the last decade in many systems such as EPR where there is a strong need to establish common standards and design a new medical information exchange model thereafter. A new integrated system for healthcare standards is necessary in order to save the costs of development and maintenance, and increase the flexibility and expandability of the systems.
　Most of the platforms currently designed for EPR in the hospitals are two-tier or three-tier architecture. Facing the huge amount of data transaction, the performance may be unacceptable. A new n-tier architecture which utilizes the modern web-service techniques is an important basis for the state-of-the-art EPR exchange model.
　The purpose of this research is therefore to investigate the distributed objects framework which integrated the XML and HL7 standards to design an efficient EPR exchange model. The necessary information and parameters of the different systems to be exchange in regarding to EPR are transferred through the Internet under this model. An empirical system is also established to illustrate the feasibility of the proposed framework. Finally, some suggestions are also proposed.
