電子病歷 (Computer-based Patient Record, CPR) 的優點除了資料儲存與取出問題優於紙本病歷之外，其次就是不同的資料可能分別安置在不同地方，電子病歷可以根據不同的需求，展現不一樣的方式。再其次，電子病歷的字體易於辨識，減少看錯率，而且病歷電子化後，調閱病歷的速度加快，將提昇服務品質而且節省病歷室的人力與空間。所以為因應龐大的門診量和加強醫療品質，推動病歷電子化是今後的趨勢。

近年來醫療院所利用網路來交換資料的需求逐漸增加，因此電子病歷的發展將有助資料的快速存取。一方面隨著網路的蓬勃發展以及多媒體技術的進步，多媒體應用於資料傳輸及使用介面上也日趨成熟。對於醫院來說，可以增進效率並節省通訊成本。對於醫師而言，能快速掌握完整的病歷資料，有助於醫師的診斷，進而提升醫療品質。在資料傳輸的過程中，需要有可依循的交換標準，其主要目的便是在提供不同應用程式之間資訊交換的標準，以減少自訂的系統介面協定，進而便利醫療資訊的流通。

本文主要努力方向在建構一個高效率的電子化診療助理系統，在使用上配合多媒體技術提供操作者友善的介面，在資料擷取方面除了電子病歷外還包括醫學影像，希望提供醫療院所實行相關計畫時的參考。

Computer-based Patient Record (CPR) has been considered with more advantages of data storing and accessing comparing to paper patient record. Furthermore, CPR also can present distinct phase according to different demand even though data are distributed. Additionally, users can reduce mistakes because CPR is easy to identify. After patient record is computerized, the speed of acquiring and quality of service will be improved, the space and manpower of patient record room can be saved. Therefore, in order to handle huge outpatient services and to enhance quality of medical treatment, CPR is a trend in future.
The demands trend of hospitals using network to exchange data are increasing recently, therefore the development of CPR will help to access data quickly. As the technologies of network and multimedia develop vigorously, it is growing up day by day with the application of multimedia in transferring data and user interface. The hospitals hope to increase efficiency and save costs of communication. The doctors need to get a fully patient record quickly to help diagnosing, and then improve quality of medicine. The processing of data transmission needs to follow a standard protocol and its primary goal is to provide standards for medical data exchange, to simplify custom interfaces in programming, and to share the medical information.
In the study, primary goal is to provide an effective electronic consultation agent system. It can provide a friendly user interface with multimedia and retrieve data about CPR and medical image. Finally, this will be recommended as a reference for relative studies.
