Purpose This study aimed to clarify the concept of nursing competence in coping with clinical deterioration by employing Rodgers’ evolutionary concept analysis, which reflects both sociocultural and temporal dimensions. Methods: A six-step concept analysis was conducted following Rodgers’ methodology. A systematic literature review was performed using PubMed, Embase, CINAHL, and Google Scholar, yielding 35 relevant studies published between 2000 and 2025. Data extraction followed the Joanna Briggs Institute template, and quality was appraised using the STROBE checklist. Results: Four key attributes of nursing competence were identified: technical skills in patient monitoring, situational awareness and clinical intuition, decision-making regarding escalation of care, and communication and teamwork to ensure timely intervention. Antecedents included formal education, clinical experience, and institutional support. Consequences encompassed enhanced patient safety, increased nurse confidence, and greater professional autonomy. The concept was demonstrated to be dynamic and influenced by healthcare policies, such as the implementation of rapid response systems. Conclusion: Nursing competence in managing clinical deterioration is a multidimensional and evolving concept that is essential for patient safety. Clarification of this concept can inform the development of assessment tools and simulation-based education. Further research should explore its application across diverse healthcare contexts and address challenges related to escalation of care.
