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.
