摘要： 目的探究负性情绪在ICU护士心理负荷与报警疲劳间的中介效应。方法 2023年1—3月,采用便利抽样法,选取四川省10家不同等级医院（三级甲等医院和三级乙等医院各3所、二级甲等医院和二级乙等医院各2所）的6个ICU（急诊ICU、综合ICU、儿科ICU、神经ICU、骨科ICU、感染ICU）206名护士作为调查对象。采用一般资料问卷、抑郁-焦虑-压力量表简体中文版、NASA任务负荷指数量表、临床报警疲劳调查问卷对其进行调查,采用SPSS23.0分析ICU护士心理负荷、负性情绪和报警疲劳的相关性,采用AMOS28.0分析ICU护士心理负荷对报警疲劳的中介效应。结果本研究ICU护士负性情绪总分为17.00（10.00,24.00）分,心理负荷总分为（87.50±13.55）分,报警疲劳总分为（24.18±5.66）分。ICU护士心理负荷总分与报警疲劳总分呈正相关（r_s=0.615,P<0.01）,与负性情绪总分呈正相关（r_s=0.463,P<0.01）;报警疲劳总分与负性情绪总分呈正相关（r_s=0.619,P<0.01）。负性情绪在ICU护士心理负荷与报警疲劳间发挥部分中介效应,中介效应值为0.232,占总效应的32.49%。结论 ICU护士的负性情绪总体呈偏低水平,报警疲劳、心理负荷总体处于中等偏高水平。ICU护士的心理负荷不仅能直接影响报警疲劳,还可以通过负性情绪间接影响报警疲劳。建议护理管理者采取积极措施以降低ICU护士心理负荷和负性情绪,进而缓解报警疲劳。

Abstract: Objective To explore the mediating effect of negative emotions on psychological load and alarm fatigue in ICU nurses. Methods Convenience sampling was used to select 206 nurses from 6 specialized ICUs (Emergency Intensive Care Unit, Intensive Care Unit, Pediatric Intensive Care Unit, Neuro Intensive Care Unit, Orthopedic Intensive Care Unit and Infection Intensive Care Unit) were selected from 10 hospitals of different grades in Sichuan Province (3 tertiary grade-A hospitals, 3 tertiary grade-B hospitals, 2 secondary grade-A hospitals and 2 secondary grade-B hospitals) from January to March 2023. The general information questionnaire, Depression-anxiety-stress Scale (Simplified Chinese version), NASA Task Load Index Scale and Clinical Alarm Fatigue Questionnaire were used to conduct the survey among the nurses.SPSS 23.0 was used to analyze the correlation between psychological load, negative emotions and alarm fatigue of ICU nurses, and AMOS 28.0 to analyze the mediating effect of psychological load on alarm fatigue in ICU nurses. Results The total score of negative emotions, psychological load and alarm fatigue was 17.00 (10.00, 24.00), 87.50±13.55 and 24.18±5.66 respectively. The total score of psychological load was positively correlated with that of alarm fatigue (r_s=0.615, P<0.01), and that of negative emotion (r_s=0.463, P<0.01). The total score of alarm fatigue was positively correlated with that of negative emotion (r_s=0.619, P<0.01). Negative emotion played a partial mediating effect between pshchological load and alarm fatigue in ICU nurses, and the mediating effect value was 0.232, accounting for 32.49% of the total effect. Conclusion The negative emotions of ICU nurses are generally at a low level, and alarm fatigue and psychological load are generally at a medium high level. The psychological load of ICU nurses can not only directly affect alarm fatigue, but indirectly affect alarm fatigue through negative emotions. It is suggested that nursing managers should take active measures to reduce the psychological load and negative emotions of ICU nurses, so as to relieve alarm fatigue.
