Phenomenological research method in qualitative research was used to conduct face-to-face and semi-structured in-depth interviews with the research subjects. Colaizzi 7-step analysis method was used to collect and sort the data and analyze and refine the topics.Results:ICU nurses' cognition in pediatric delirium assessment could be classified into four themes, including changes of ICU nurses' cognition of pediatric delirium assessment, obstacles to pediatric delirium assessment, promoting factors for pediatric delirium assessment, and ICU nurses' concern about the collaborative intervention of medical team after the positive delirium assessment.Conclusions:The main manifestations of ICU nurses in this study are the lack of understanding of the evaluation of delirium, the obstacles encountered in the evaluation process, and the lack of collaboration between the medical and nursing team. In order to improve the convenience and accuracy of ICU nurses' assessment of delirium, it is recommended to strengthen the training of medical staff for delirium, gradually optimize the obstacles to the implementation of the assessment, encourage the cooperation of medical teams and develop a delirium assessment process in line with children's ICU according to the working situation and mode of ICU.
