National Early Warning Score를 손상 환자에게도 사용할 수 있는가?

초록

Objective: The National Early Warning Score (NEWS) is used widely to detect deteriorating patients in a range of clinical situations. This study examined the ability of the NEWS to predict poor outcomes in trauma patients. Methods: This was a retrospective observational study using a dataset collected prospectively from trauma patients who visited the emergency department of a tertiary referral center in the southern area of the Republic of Korea. The area under the receiver operating curves (AUC) of the Revised Trauma Score (RTS) and NEWS were compared. The primary outcome was in-hospital mortality. Results: Among 17,661 patients finally enrolled, 66.3% were male, and the median age was 49 (34-64). The AUC of the NEWS and RTS were 0.878 (95% confidence interval [CI], 0.873-0.883) and 0.827 (95% CI, 0.821-0.833) (AUC difference, 0.051; 95% CI, 0.025-0.077; P<0.01), respectively. The sensitivity and specificity of the NEWS were 74.0% and 91.2%, respectively, at a cutoff of four, and those of the RTS were 67.7% and 96.1%, respectively, at 7.55. Conclusion: The NEWS showed better performance in predicting the in-hospital mortality of patients with trauma compared to the RTS.
