Abstract

Various early warning score tools have been developed to identify clinical deterioration in patients. This study assessed the predictive capacity of the National Early Warning Score 2 (NEWS-2) in the prehospital setting to predict death within 24 hours and 30-day intensive care unit admission.

A single-center observational retrospective study was conducted in the emergency medical services (EMS) of King Abdulaziz Medical City, Riyadh, Saudi Arabia. We included adult patients (> 18 years) who attended the emergency medical service. The primary outcome was 24-hour death and 30-day intensive care unit admission. Sensitivity, specificity, and negative/positive predictive values (NPV/PPV) were determined.

The study comprised 1,343 eligible patients. NEWS-2 exhibited a sensitivity of 20% and a specificity of 80% for predicting 24-hour death and a sensitivity of 10% and a specificity of 80% for predicting 30-day intensive care unit admission. The area under the curve for predicting death was 0.529, and for intensive care unit admission was 0.456.

Our study underscores the limited utility of NEWS-2 as a predictor of 24-hour death and 30-day intensive care unit admission in adult patients utilizing the emergency medical service. Further extensive studies are warranted to corroborate this study’s findings.
