Abstract

Abstract:

Objective To investigate critical care nurses’ cognition and application status regarding the group standard “Endotracheal Suctioning in Adults Receiving Invasive Mechanical Ventilation”，and to assess its clinical implementation level and effectiveness，so as to provide a basis for developing targeted intervention strategies. Methods A cross-sectional survey was conducted among critical care nurses from 17 provinces and cities across China between October and December 2024，using convenience sampling. Data were collected using a self-developed questionnaire based on the Capability，Opportunity，Motivation and Behaviour（COM-B） model. Binary logistic regression was employed to analyze the factors influencing critical care nurses’ practice level. Results A total of 1 110 questionnaires were distributed，with 1 057 valid responses retained for analysis. The total practice score among Critical care nurses was 197（169，225） points. Binary logistic regression identified age，senior professional title，awareness of the “Standards”，having a standardized endotracheal suctioning procedure in the department，receiving training and interpretation on the “Standards”，and implementation situation as significant facilitators of clinical practice（P<0.05）. Conclusion Critical care nurses’ clinical practice regarding the group standard "Endotracheal Suctioning in Adults Receiving Invasive Mechanical Ventilation" needs improvement and encounters a range of obstacles. It is recommended that managers implement precise interventions based on the identified influencing factors to enhance standard compliance，optimize the quality of endotracheal suctioning care，and promote the effective clinical application of the group standard.

摘要：

目的调查急危重症护士对《成人有创机械通气气道内吸引技术操作》团体标准（简称《标准》）的认知和应用情况，评估《标准》的执行程度和效果，为制订针对性干预策略提供依据。方法于2024年10—12月，采用便利抽样法，选取17个省市的急危重症护士作为调查对象。基于能力-机会-动机-行为理论自行设计问卷，开展横断面调查。采用二元Logistic回归分析急危重症护士执行《标准》的影响因素。结果共回收问卷1 110份，有效问卷1 057份，急危重症护士《标准》实践总分为197（169，225）分。二元Logistic回归分析显示，年龄、职称、知晓《标准》、科室有气道内吸引操作标准流程、参与过《标准》培训、参与过《标准》解读以及实施《标准》情况是急危重症护士执行《标准》的影响因素（P<0.05）。结论急危重症护士对《标准》的实践水平有待提升，且面临多维度障碍。建议管理者基于已识别的影响因素，采取精准干预措施，以提升急危重症护士执行《标准》的依从性，优化气道内吸引护理质量，推动《标准》的临床应用。
