Potential profile analysis and influencing factors of alarm fatigue in ICU nurse

Abstract

Abstract: Objective To explore the potential types and characteristic differences of alarm fatigue among nurses in intensive care unit（ICU）,and analyze the related influencing factors. Methods Convenience sampling was used to select 276 nurses from 3 kinds of ICUs（comprehensive ICU,neurosurgical ICU,emergency ICU） in 10 hospitals in Sichuan Province as the survey objects from January to May 2023. General information questionnaire,clinical alarm fatigue scale,depression anxiety stress scale（DASS-21） and the national aeronautics and space administration（NASA） mission compliance index were used to analyze the potential profile of alarm fatigue characteristics of ICU nurse. The influencing factors of the potential profile were identified by single factor analysis and logistic regression analysis. Results The total score of alarm fatigue scale of ICU nurses was（24.40±6.84）points,the total score of psychological load scale was （87.83±15.51）points,and the total score of negative emotion scale was 17.00（9.00,26.00）points. The alarm fatigue of ICU nurses could be divided into three potential profiles,namely,high fatigue-high stress group[78 individuals（28.26%）],moderate fatigue-low concentration group[134 individuals（48.55%）],mild fatigue-low mood group[64 individuals（23.19%）]. The results of unordered multi-classification logistic regression analysis showed that compared with moderate fatigue and low concentration group,stress（OR=1.260,P<0.05） and load perception（OR=1.137,P<0.01） were the predictors of high fatigue and high stress group,while anxiety（OR=0.775,P<0.05）,stress（OR=0.716,P<0.01）,provincial hospitals（OR=0.260,P<0.05） and working experience of 0-<5 years（OR=8.005,P<0.05） were the predictors of mild fatigue and low mood group. Conclusion The alarm fatigue characteristics of ICU nurses are heterogeneous and can be divided into 3 potential profiles. Nursing managers can individually intervene ICU nurses according to the influencing factors of different potential profiles to reduce alarm fatigue.
