To select and obtain relevant evidence of airway management in adult critically ill patients at home and abroad, formulate clinical quality review indicators based on evidence and analyse obstacle factors and promoting factors in evidence-based nursing practice. To promote standardized ICU airway management evidence-based nursing practice to provide the basis. Obstacle factor analysis. Take the Joanna Briggs Institute (JBI) evidence-based healthcare model as theoretical guidance, establish evidence-based problems, form a team, systematically search for literature, evaluate quality and summarize evidence, establish quality review indicators and review methods, analyse obstacles and facilitating factors based on the review results and formulate corresponding action strategies. According to the 29 best evidences, 21 review indicators were developed. Through the results of clinical quality review, the main barriers to evidence-based practice were analysed the lack of nurse training and relevant evidence-based knowledge at the practitioner level, the lack of standardized procedures for airway management and the lack of materials at the system level. There is a big gap between airway management evidence and clinical practice in critically ill adult patients. Therefore, improvement measures should be formulated for obstacle factors to promote effective transformation of evidence into clinical practice.
