摘要

由於電腦科技的進步，各醫療院所的病歷電腦化已經非常普遍，跨醫院交換電子病歷的需求也越來越高。在衛生署的支持下，近年來已經有多位專家學者投入電子病歷交換的研究，雖然已有部分的研究成果，但在實務應用上仍不普遍。本篇論文將探討近年來國內電子病歷交換的發展，並且提出了一個以健康第七層通訊協定（HL7）查詢訊息為主的電子病歷交換系統的架構，在系統雛形中為醫院端建立一個電子病歷交換主機，可以透過網路連結醫院的病歷資料庫系統並且交換HL7訊息；各醫院的病歷交換主機向病歷交換中心註冊，由一部索引伺服器來管理各個交換主機的網址及加解密金鑰。我們已經完成一個簡單的病歷交換系統，實際模擬HL7查詢訊息的編碼、解碼、加密、解密的功能，可以迅速安全的傳送電子病歷。

Because of the rapid improvements in computers and communication technologies during the last few years, electronic medical records have been used extensively in hospitals. Moreover, pressure is growing to regulate data exchange among healthcare organizations. Although the government has allocated funding for numerous projects and studies in this field for several years already, and has achieved some important goals, complete implementation of medical records exchange across all hospitals is still difficult. This study discusses existing implementations of medical record exchange in the domestic health environment and a new record-exchange architecture employing Health Level Seven (HL7) query messages. The exchange interface servers are established for hospitals to manage the information communication through the intra- and inter-hospital network linked with a medical records database. An index service center can be given responsibility for managing the exchange interface servers and publishing the addresses and public keys. The prototype machine has been implemented in this study to generate, parse and transfer the HL7 query messages. Moreover, the system can also encrypt and decrypt a message using the public key encryption algorithm and can quickly and securely transmit medical records.
