Abstract: Objective: To develop a risk assessment scale for unplanned extubation of adult tracheal intubation patients, providing a reliable and quantitative assessment tool for preventing unplanned extubation of tracheal intubation and improve the quality of nursing safety management. Methods: Guided by the evidence-based theory of Hopkins, we conducted evidence synthesis and panel discussion, and initially constructed the item pool of the scale. The content system of the scale was determined through 3 rounds of expert consultation. The weight of the items were determined through the analytic hierarchy process, forming a test version. The test version of the scale was used to assess the risk of unplanned extubation of adult patients with tracheal intubation, and the reliability and validity of the scale were analyzed. Results: The risk assessment scale for unplanned extubation of adult tracheal intubation included 9 items and 28 classification items. The active coefficients of the three rounds of expert consultation were 88.24%, 100.00%, and 100.00%. The expert authority coefficient was 0.91. The expert coordination coefficient was 0.329-0.759. The reliability and validity of the scale met the standard, indicating that the reliability and validity were good. Conclusion: Based on the results of evidence-based analysis, the Delphi expert consultation and analytic hierarchy process were used to construct the risk assessment scale for unplanned extubation of adult tracheal intubation, in order to effectively improve clinical care quality for patients with tracheal intubation.
