摘要目的:了解ICU护士对重型颅脑损伤（STBI）患者目标体温管理（TTM）知信行现状并分析其影响因素，为开展ICU护士STBI患者TTM培训提供参考依据。方法:应用横断面研究的方法，2022年11—12月采用分层整群抽样法按一、二、三级医院进行分层，采用自行设计的ICU护士对STBI患者TTM现状调查问卷，对甘肃省11个市的22所二、三级医院的神经外科ICU、急诊ICU及综合ICU护士的知信行现况进行调查，采用多元线性回归分析法分析ICU护士知识、态度及行为得分的影响因素。结果:共回收有效问卷543份。ICU护士对STBI患者TTM总分、知识、态度及行为维度得分分别为（76.75 ± 10.42）、（7.38 ± 2.74）、（39.57 ± 4.87）、（29.80 ± 7.18）分。多元线性回归分析结果显示，ICU护士对STBI患者TTM知识维度得分影响因素是参加过TTM相关培训（ t = 2.16， P<0.05），ICU护士对STBI患者TTM态度维度得分影响因素是大专、本科学历及护士长岗位（ t = 2.65、2.91、2.14，均 P<0.05），ICU护士对STBI患者TTM行为维度得分影响因素是36~45岁年龄段、所在科室有TTM相关标准及了解TTM相关指南（ t = - 2.46、2.64、3.85，均 P<0.05）。 结论:ICU护士对STBI患者TTM态度较为积极，知识和行为水平均有待提高。管理者应针对现况及影响因素开展相关培训，提高ICU护士对STBI患者TTM的认知及实践能力，确保TTM的有效性及安全性。

abstractsObjective:To understand the current situation of knowledge, attitude and practice about target temperature management (TTM) in patients with severe traumatic brain injury (STBI) among intensive care unit ICU nurses and analyze the influencing factors, so as to provide a reference for conducting ICU nurses′ TTM training for patients with STBI.Methods:Applying the method of cross-sectional study, from November to December 2022, a stratified whole-group sampling method was used, stratified by first-, second-, and third-level hospitals, and a self-designed questionnaire on the current status of ICU nurses′TTM for patients with STBI was used to investigate the current status of knowledge, attitude, and practice of neurosurgical ICU, emergency ICU, and comprehensive ICU nurses in 22 second- and third-level hospitals in 11 cities in Gansu Province, and multiple linear regression analysis was used to analyze the factors influencing ICU nurses′ knowledge, attitude, and practice scores.Results:A total of 543 valid questionnaires were returned, and the scores of ICU nurses on the TTM total score, knowledge, attitude and practice dimensions of STBI patients were (76.75 ± 10.42), (7.38 ± 2.74), (39.57 ± 4.87), (29.80 ± 7.18) points respectively. The results of multiple linear regression analysis showed that the factor influencing ICU nurses′ scores on the TTM knowledge dimension for STBI patients was having attended TTM-related training ( t = 2.16, P<0.05); the factors influencing ICU nurses′ scores on the TTM attitude dimension for STBI patients were college, bachelor′s degree and the position of nurse practitioner ( t = 2.65, 2.91, 2.14, all P<0.05); and the factors influencing ICU nurses′ scores on the TTM practice dimension for STBI patients were the age group of 36 to 45 years old, the department having TTM-related criteria and having knowledge of TTM-related guidelines ( t = -2.46, 2.64, 3.85, all P<0.05). Conclusions:ICU nurses have a more positive attitude toward TTM in patients with STBI, but the level of knowledge and practice needs to be improved. Managers should conduct relevant training according to the current situation and influencing factors to improve ICU nurses′ knowledge and practice of TTM in patients with STBI, ensuring the effectiveness and safety of TTM.
