| ABSTRACT |
Objective:
An external validation of the Study of the Management of Blunt Chest Wall Trauma (STUMBL) score was conducted in a Korean emergency department setting.
Methods:
A single-center, retrospective study was performed on patients with isolated blunt chest trauma who visited the emergency department of Eulji University Hospital, Daejeon, from January 1 to December 31, 2019. The area under the receiver operating characteristic curve (AUROC) was calculated, and cut-off values corresponding to the complications risks, intensive care unit (ICU) admission, and prolonged length of stay (LOS) were calculated using the Youden index.
Results:
Seven hundred and forty-five patients were enrolled in this study. The AUROC for all composite outcomes was 0.90 (95% confidence interval [CI], 0.88-0.93); the AUROCs for the prolonged LOS arm of 7 days or more and for the ICU admission group were 0.91 (95% CI, 0.88-0.94) and 0.96 (95% CI, 0.94-0.97), respectively. The calculations based on the Youden index found that optimal cut-off values were greater than 12 for the complication group, greater than 18 for ICU admission, and greater than 14 for the prolonged LOS group.
Conclusion:
This validation study revealed the robust effectiveness of the STUMBL scoring system in predicting the outcomes of patients with blunt chest trauma. |
