摘要

龐大的軟硬體投資與維護經常阻礙醫療資訊業者的成長與進步，並且在新技術不斷地推陳出新下，也帶給醫療資訊業者很大的壓力。近來醫療資訊系統新的趨勢與挑戰，是將醫療決策支援系統從醫療資訊系統中分離出來成為一種決策支援的服務型態。
本篇文章藉由探討台大醫院醫療資訊系統成功的建置經驗，驗證我們所提出的資訊整合於服務導向醫療決策支援系統之架構。此架構立基於大型的、協同整合的、分散式的、企業醫療資訊系統，並且應用於有線及無線網路的醫療環境中。為了能夠順利地從舊有的系統中轉型成新的系統架構，我們採用多層的組織架構，並利用服務導向的結構來整合與溝通異質的元件與資料庫，同時我們也採用HL7等標準來實作中介軟體及訊息的交換。

Healthcare vendors are often hindered in their efforts to evolve due to extensive existing investments in hardware, software, and medical devices, that they must continue to maintain, while at the same time coming under pressure to innovate new systems. A new trend and challenge in healthcare information-based services systems is to separate healthcare clinical information from health application systems.
In this thesis, we present the successful experiences of an integrated, collaborative, distributed, large-scale Enterprise Healthcare Information System (EHIS) constructed over both wired and wireless infrastructure at the National Taiwan University Hospital. In order to smoothly and sequentially transfer from the complex relations among the old (legacy) systems to the new generation EHIS, we adopted a multi-tier framework based on service-oriented architecture (SOA) to integrate the heterogeneous systems as well as allow for interoperation among many other components and multiple databases. We also present mechanisms of the logically layer reusability approach and data (message) exchange flow via HL7 Middleware, DICOM standard and the IHE workflow. Meanwhile, we propose and verify an Information Services for Healthcare Decision Support System based on the NTUH Healthcare Information System (HIS).
