Method： Walker and Avant’sstrategy of analysis was adopted to this research. Results： ICU delirium is defined as the presence of an acute cognitiveimpairment, accompanied by a disturbance of consciousness with fluctuating inattention, and the array of dysfunctionsonly developed for a short period of time in ICU. The antecedents of ICU delirium include （1） the high severity of illness,（2） pain, （3） sedative use, （4） immobilization, （5） sleep deprivation and （6） unpleasant awareness. The consequencesinvolve （1） promoting the risks of self-extubation and unplanned removal of catheters, （2） prolonging the length of ICUstay, （3） increasing the mortality of critical patients and （4） Some different ICU delirium assessment instruments aregathered. Confusion Assessment Method for Intensive Care Unit assessment tool （CAM-ICU） was the most populardiagnostic tool used by nurses. Conclusion： Concept analysis as an extension and development of nursing theory cancreate a linkage between practice and theory. It will create a knowledge foundation of ICU delirium and provide atheoretical basis to construct nursing theory. This study can help ICU nurses to understand and recognize ICU delirium.ICU nurses will be enlightened to develop effective interventions of ICU delirium to improve critical patients’ clinicaloutcomes.展开更多
