疲憊是一個主觀且不愉快的感覺，臨床上護理人員因而不易發現個案有疲憊的現象，有時甚至將之與其他概念相混淆。本文主要目的乃藉由概念分析的方法，以澄清與分析「疲憊」之概念。採Walker與Avant （1995）的概念分析步驟進行，希望藉此概念分析步驟，使護理人員對疲憊有更深一層的認識，並可做為日後發展理論架構及當做研究的基礎。

　　　　　Fatigue is a subjective and unpleasant feeling that is often unrecognized by clinical nurses, and sometimes easily confused with other concepts. The purpose of this report was to conduct a concept analysis to clarify and define fatigue and its components. The analysis was based on the steps and techniques proposed by Walker and Avant (1995). Results will help nurses to better understand and assess fatigue in their patients, and provide a basis for theory development and research.
