Objective: To investigate the status of knowledge, attitude, and behavior of enteral nutrition implemented by nurses in burn intensive care unit (BICU) and analyze its influencing factors. Methods: A multi-center cross-sectional survey research method was used. On May 8th, 2022, 107 BICU nurses who met the inclusion criteria were selected from the burn departments of the First Affiliated Hospital of Army Medical University (the Third Military Medical University), Guangdong Provincial People's Hospital, the First Affiliated Hospital of Guangxi Medical University, the Affiliated Hospital of Qinghai University, the Second Affiliated Hospital of Air Force Medical University, the Affiliated Hospital of Nantong University, Guiyang Steel Factory Staff Hospital, and the Second Affiliated Hospital of Kunming Medical University. The self-made nurses' enteral nutrition nursing knowledge-attitude-behavior questionnaire for severely burned patients was used to investigate the nurses' gender, age, working years, professional title, position, highest educational background, and whether they received systematic training in knowledge of enteral nutrition, the scores of each factor, and the total scores of knowledge, attitude, and behavior dimensions of enteral nutrition in nurses. The nurses were classified according to the general data, and the total scores of their knowledge, attitude, and behavior of enteral nutrition were calculated. Data were statistically analyzed with independent sample t test, one-way analysis of variance, Mann-Whitney U test, and Kruskal-Wallis H test. According to the results of univariate analysis and combined with clinical experience and significance, the generalized linear model analysis was carried out to screen the independent influencing factors of the total scores of knowledge, attitude, and behavior of enteral nutrition in BICU nurses. Results: A total of 107 nurses were surveyed, and 107 valid questionnaires were collected, with an effective recovery rate of 100%. In the BICU nurses' enteral nutrition knowledge-attitude-behavior questionnaire, the total scores of knowledge, attitude, and behavior were 44±13, 87±15, and 70±19, respectively. Most of the BICU nurses in this survey were female, aged 22-48 (31±6) years, and the number of nurses worked for 1-5, 6-10, and ≥11 years was evenly distributed. The majority of the professional titles of nurses were nurses, positions were responsible nurses, and the highest educational background was undergraduate. Forty-four nurses received systematic training in knowledge of enteral nutrition. There were statistically significant differences in the total scores of knowledge of enteral nutrition among BICU nurses with different ages, working years, professional titles, positions, highest educational background, and whether they received systematic training in knowledge of enteral nutrition (with H values of 27.36, 15.27, and 10.19, respectively, Z values of -3.33, -2.59, and -6.46, respectively, P<0.05). There were no statistically significant differences in the total scores of attitude and behavior of enteral nutrition among BICU nurses with different gender, ages, working years, professional titles, positions, highest educational background, and whether they received systematic training in knowledge of enteral nutrition (P>0.05). Age (26-30, 31-35, and ≥36 years old), highest educational background (undergraduate), and the systematic training received in enteral nutrition knowledge were the independent influencing factors for the total score of knowledge of enteral nutrition in BICU nurses (with 95% confidence intervals of 0.12-0.36, 0-0.30, 0.03-0.31, 0.01-0.32, and 0.19-0.40, respectively, standardized regression coefficients of 0.24, 0.15, 0.17, 0.17, and 0.29, respectively, P<0.05). There were no independent influencing factors for the total scores of enteral nutrition attitude and behavior of BICU nurses in different characteristics (P>0.05). Conclusions: The BICU nurses have low cognitive level in the implementation of enteral nutrition, their concept needs to be updated in time, and their behavior needs to be further standardized. Age (26-30, 31-35, and ≥36 years old), highest educational background (undergraduate), and the systematic training received in enteral nutrition knowledge were the independent influencing factors for the knowledge of enteral nutrition in BICU nurses.
目的： 调查烧伤重症监护病房（BICU）护士实施肠内营养护理的知信行现状并分析其影响因素。 方法： 采用多中心横断面调查研究方法。2022年5月8日，选择陆军军医大学（第三军医大学）第一附属医院、广东省人民医院、广西医科大学第一附属医院、青海大学附属医院、空军军医大学第二附属医院、南通大学附属医院、贵阳钢厂职工医院、昆明医科大学第二附属医院烧伤科的107名符合入选标准的BICU护士作为调查对象。采用自制严重烧伤患者肠内营养护理知信行调查问卷调查护士的性别、年龄、工作年限、职称、职务、最高学历、是否接受肠内营养知识系统培训，以及肠内营养知识、态度、行为维度的各因子得分及总得分。将护士按照一般资料分类，统计其肠内营养知识、态度、行为的总得分。对数据进行独立样本t检验、单因素方差分析、Mann-Whitney U 检验、Kruskal-Wallis H 检验。根据单因素分析结果，再结合临床经验和意义，进行广义线性模型分析，筛选BICU护士肠内营养知识、态度、行为总得分的独立影响因素。 结果： 接受本次调查的护士共107名，收回有效问卷107份，有效回收率为100%。BICU护士肠内营养知信行问卷中，知识、态度、行为总得分分别为（44±13）、（87±15）、（70±19）分。本次调查的BICU护士大多数为女性，年龄为22~48（31±6）岁，工作年限为1~5、6~10、≥11年的人数分布较平均，大多数护士职称为护师、职务为责任护士、最高学历为本科，有44名护士接受过肠内营养知识系统培训。不同年龄、工作年限、职称、职务、最高学历、是否接受肠内营养知识系统培训的BICU护士肠内营养知识总得分比较，差异均有统计学意义（H值分别为27.36、15.27、10.19，Z值分别为-3.33、-2.59、-6.46，P<0.05）；不同性别、年龄、工作年限、职称、职务、最高学历、是否接受肠内营养知识系统培训的BICU护士肠内营养态度、行为总得分比较，差异均无统计学意义（P>0.05）。年龄（26~30、31~35、≥36岁）、最高学历（本科）、接受肠内营养知识系统培训均是BICU护士肠内营养知识总得分的独立影响因素（95%置信区间分别为0.12~0.36、0~0.30、0.03~0.31、0.01~0.32、0.19~0.40，标准化回归系数分别为0.24、0.15、0.17、0.17、0.29，P<0.05），而不同特征下均无BICU护士肠内营养态度、行为总得分的独立影响因素（P>0.05）。 结论： BICU护士实施肠内营养的认知水平偏低，观念须及时更新，行为也有待进一步规范。年龄（26~30、31~35、≥36岁）、最高学历（本科）、接受肠内营养知识系统培训均是BICU护士肠内营养知识的独立影响因素。.
