There has been little research into the experience of powerlessness in dialysis patients. To improve the clinical care of dialysis patients that experience powerlessness；the concept should be analyzed and refined to improve care personnel’s knowledge in this area. Concept analysis is a method for exploring and evaluating the meaning of words. The aim of this paper is to provide an in-depth analysis on the concept of powerlessness and thus facilitate understanding of the term. An attempt has been made to apply the Walker and Avant (2005) concept analysis process to the context of powerlessness. A concept analysis provides a logical basis for defining terms through a definition of the attributes；case examples (model, contrary；borderline)；antecedents；consequences and empirical referents. The paper concludes with an exploration of the implications and applications of powerelessness in dialysis nursing. The historical background and literature are reviewed using concept analysis to bring the term into focus and clariy its definition. By identifying the attributes of powerlessness；communication between health professionals involved in the practice, research and education of dialysis nursing can be enhanced.
