Introduction: Intuition is an abstract concept, applied to make decision and judgment about clinical issues of patients by nurses. Regarding ambiguity and lack of information on the concept, this study was conducted to analyze the concept of intuition in nursing.Methods: The Walker and Avant method was used for concept analysis, which consists of 8 steps including: 1- selection of a concept, 2- determination of the aims of analyses, 3- Identification of all uses of the concept, 4- Determination of the defining attributes, 5- Identification of a model case, 6- Identification of borderline, related, contrary and invented cases, 7- Identification of antecedents and consequences, 8- Definition of empirical referents.Results: The results showed that the defining attributes of the concept of intuition in nursing included: 1- knowledge achievement as holistic and no process of staging, 2- knowledge perception as immediately, 3- the perception of intuition as a feeling or thought, 4- the perception of intuition unconsciously and spontaneity, 5- the perception of intuition accompanied by physical and psychological signs, 6- dissimilarity between intuitive messages with clinical symptoms of patients, 7- prediction of patient conditions via intuition, 8- improvement of patient status by incorporating the intuition in the nursing care plan. For clarification, simultaneously with these stages, cases such as model, borderline, and contrary cases were offered.Conclusions: In this study, the concept analysis of intuition was performed, hence, the results would be provide a comprehensive and reliable image regarding the use of intuition in nursing, thus, further qualitative and quantitative investigations about intuition are suggested in various nursing settings.
