Abstract Objective To explore the influence of occupational stress on alarm fatigue of intensive care unit (ICU) nurses, and to analyze the mediating role of mental resilience in occupational stress and alarm fatigue of ICU nurses. Methods Using the cluster sampling method, from October to November 2020, a total of 752 ICU nurses in six general hospitals in Shanghai (Shanghai Sixth People’s Hospital, Shanghai Huashan Hospital, Shanghai Ruijin Hospital, Shanghai Cancer Hospital, Shanghai Eighth People’s Hospital, Shanghai Jinshan Central Hospital) were respectively treated with job stressors scale, ICU nurse alarm fatigue scale and mental resilience scale table Chinese version (CD-RISC) for investigation and analysis. Results The occupational stress scores of ICU nurses with different hospital grades, age, gender, education background, years of working in ICU, marital status, children, monthly income, shift number in the last three months, and blood type were statistically significant (P＜0.05). The occupational stress scores of different work/life events in the past three months were compared, and the differences were statistically significant (P＜0.05). Correlation analysis showed that the scores of each dimension of occupational stress of ICU nurses were negatively correlated with the scores of each dimension of mental resilience (r＜0, P＜0.05), and positively correlated with the scores of alarm fatigue (r＞0, P＜0.05). Linear regression results showed that ICU nursing staff working years, children, shift, dimission thoughts, alarm fatigue, and mental resilience were the factors influencing occupational stress (P＜0.05). The relationship between occupational stress, alarm fatigue, and mental resilience of ICU nurses were linear, and the mediating effect was verified. The mediating effect value of mental resilience was 0.134, accounting for 64.73% of the overall effect. Conclusion Occupational stress of ICU nurses has mediating effect on alarm fatigue through mental resilience.
