Validation of a Risk Assessment Tool for Unplanned Endotracheal Extubation: An Observational Study

The purpose of this study was to validate and determine the sensitivity and specificity of the risk assessment tool for unplanned endotracheal extubation. Unplanned endotracheal extubation is a common adverse event. The rate of unplanned endotracheal extubation is an indicator to measure patient safety and medical quality. This study was conducted in five intensive care units in a tertiary-A hospital. A total of 227 samples encounters were obtained from 147 unique patients. The content validity was 0.91, and the item content validity ranged from 0.80 to 1.00. Cronbach's alpha was .58, the interrater reliability was .93. The area under the curve was 0.89 (95% CI [0.84, 0.94], p < 0.01), the sensitivity was 87.80%, and the specificity was 74.20%. This tool presented good reliability and validity and can be used to assess the risk of unplanned endotracheal extubation in patients with artificial airways.
