Objective To investigate the current status of workplace cognitive failure (WCF) among ICU nurses and analyze its inf-luencing factors, providing a theoretical basis for managers to develop targeted training programs to reduce WCF among ICU nurses.Methods From January to March 2025, a survey was conducted with 361 ICU nurses from 6 tertiary public general hospitals in Shandong Province using a general information questionnaire, the Workplace Cognitive Failure Scale, the Perceived Stressors in Intensive Care Units Scale, the Work-Family Support Scale, the 10-item Connor-Davidson Resilience Scale, and the Perceived Stress Scale.Results The average score of WCF among ICU nurses was （29.14±9.63）, and 92.52% of them reported experiencing at least one episode of WCF.Among ICU nurses was positively correlated with stressors and perceived stress, and negatively correlated with work-family support and psychological resilience （all P＜0.05）.Multiple linear regression showed that education level, stressors, work-family support, psychological resilience, and perceived stress were the main influencing factors of ICU nurses′ WCF （all P＜0.05）, accounting for 51.8% of the total variance.Conclusion WCF among ICU nurses exhibits a "low severity-high prevalence" characteristic. Nursing managers need to pay attention to the status of WCF among ICU nurses, identify it early, and intervene accurately to reduce its occurrence.
