隨著行政院衛生署推動電子病歷，醫療機構將陸續增加各項資訊設備，以提升醫療照護品質與病人安全，並簡化醫療服務作業流程，降低醫院管理成本，增加教學研究及行政管理的資料統計及分析。然而資訊科技的導入，除了需考慮系統設計與推行外，亦必須考量其它多種因素如：系統是否可以降低使用者記憶的負荷、簡化工作流程與提供決策參考。本文將門診護理指導資訊系統的建置過程予以經驗分享，除了說明紙本護理指導單張資訊化過程外，並闡述如何應用決策支援系統於門診護理指導資訊系統上，進而輔助門診護理人員在快速且忙碌的工作中，亦能提供合適的護理指導單，更可進行護理指導的評值。盼能將此經驗提供給其它醫療機構未來建置護理指導資訊系統時之參考。

In line with Department of Health promotion of electronic medical records, health care institutions have increased their information technology facilities in order to improve medical quality and patient safety, streamline healthcare procedures, reduce hospital management costs, and increase the use of statistical analysis in medical teaching, research and administration. However, applying information technology must consider many factors apart from system design and development. Such other factors include effectiveness in reducing user reliance on memory faculties, ability to streamline work processes, and capacity to recommend viable decisions. This paper provides an example of the nursing instruction information system deployment process. In addition to describing the development and implementation, applications of patient education and nursing decision-making are also presented. It is hoped that this experience may serve as reference to other healthcare institutions in the process of building nursing information systems.
