資訊化時代來臨，醫療環境亦隨之變遷，越來越多的醫療業務開始改變原有的作業流程，朝向無紙化、行動化之資訊化方向邁進。資訊化將改善醫護人員的工作效率、增加病人照護安全，以及提升了醫療機構的正面形象。在資訊化發展之決策的過程中，護理資訊人員扮演了一個非常重要的角色。這個角色在資訊科技生命週期之決策環節中，影響到資訊系統發展與運用的成功與否。因此，本文就生命科技週期之「計畫期」、「分析期」、「設計、發展、修正期」及「執行、評值、支持與維護」等四個不同期程，介紹護理資訊人員在其中應具備之角色功能與專業認知，另針對護理資訊人員在決策過程中可能發生的決策瑕疵或錯誤亦進行整理闡述，期待透過本文之撰寫，讓護理資訊人員在資訊化的決策過程中，能有較佳的決策參考。

The medical environment has changed greatly with the coming of the information age, and, increasingly, the operating procedures for medical services have been altered in keeping with the trend toward mobile, paperless services. Informatization has the potential to improve the working efficiency of medical personnel, enhance patient care safety, and give medical organizations a positive image. Informatics nurses play an important role in the decision-making processes that accompany informatization. As one of the decision-making links in the information technology lifecycle, this role affects the success of the development and operation of information systems. The present paper examines the functions and professional knowledge that informatics nurses must possess during the technology lifecycle, the four stages of which include: planning, analysis, design/development/revision, and implementation/assessment/support/maintenance. The present paper further examines the decision-making shortcomings and errors that an informatics nurses may make during the decisionmaking process. We hope that this paper will serve as an effective and useful reference for informatics nurses during the informatization decision-making process.
