The Status of Knowledge-Attitude-Practice of Interruption of Enteral Nutrition Feeding in ICU Nurses and Its Mediation with Self-Efficacy

摘要: 目的：调查ICU护士肠内营养喂养中断知信行情况并分析其与自我效能感之间的关系。方法：采用便利抽样的方法，选取2020年10月25日~31日山东省12所三甲医院391名ICU护士为对象，以问卷星形式进行线上发放、线上填写、线上回收，调查内容包括一般自我效能问卷及自制喂养中断知信行调查问卷。结果：391例ICU护士喂养中断知识得分为21~86 (54.01 ± 12.85)分，态度得分为7~35 (28.10 ± 5.25)分，行为得分为7~35 (28.09 ± 5.03)分，总分为63~150 (110.19 ± 15.52)分；自我效能感在态度及行为之间起中介作用，中介效应量28.40%。结论：ICU护士对肠内营养喂养中断的态度处于较高水平，但相关知识较为缺乏，多数ICU护士无积极主动学习的意识，执行能力较差，其中自我效能感在态度和行为之间起中介作用，应通过多方努力提高ICU护士喂养中断知信行水平。

Abstract: Objective: To investigate the status of knowledge, attitude and practice of interruption of enteral nutrition in ICU nurses and analyze the relationship between them and self-efficacy. Methods: A total of 391 ICU nurses from 12 first-class hospitals in Shandong province from October 25 to 31, 2020 were selected by the method of convenience sampling, and questionnaires were distributed, filled in and collected online in the form of star questionnaire. The contents of the questionnaires included general self-efficacy questionnaire and self-made questionnaire on the knowledge, attitude and practice of interrupted feeding. Results: The knowledge scores of the 391 ICU nurses were 21~86 (54.01 ± 12.85), the attitude scores were 7~35 (28.10 ± 5.25), the practice scores were 7~35 (28.09 ± 5.03), and the total scores were 63~150 (110.19 ± 15.52). Self-efficacy plays a mediating role between attitude and practice, with a mediating effect of 28.40%. Conclusion: The attitude of ICU nurses to the interruption of enteral nutrition is fair, but the knowledge is relatively lack, most of ICU nurses have no awareness of active learning and poor executive ability. Among them, self-efficacy plays a mediating role between attitude and behavior, so efforts should be made to improve the level of knowledge, attitude and practice of the interruption of enteral nutrition of ICU nurses.
