To evaluate the prognostic value of early warning score (EWS) in predicting in-hospital mortality among patients with acute aortic dissection (AAD).
Approach:
Study Design: Retrospective analysis of consecutive AAD patients presenting to the emergency department in 2022.
Data Collection: Collected demographic information, clinical characteristics, EWS, laboratory findings, and time to computed tomography angiography (CTA).
Statistical Analysis: Performed univariable and multivariable logistic regression analyses to identify risk factors for in-hospital mortality.
Key Findings:
NEWS demonstrated the highest discriminative performance among the three EWS with an AUC of 0.581 (95% CI 0.528–0.634).
Interpretation:
NEWS may serve as a tool for initial risk stratification in patients with AAD, although its overall predictive ability is modest.
Limitations:
Retrospective design may introduce selection bias.
Data limited to a single institution may affect generalizability.
Conclusion:
Type A AAD and surgical treatment were the only independent predictors of in-hospital mortality.
