Short National Early Warning Score (NEWS) is used to recognize clinical deterioration in patients. This study developed a modified early warning score using fewer variables to reduce errors. The prospective study analyzed data from 6 wards in a Portuguese hospital between 2009-2013. Two new scales were created using fewer vital signs. Both new scales showed superior ability to predict outcomes like survival compared to the original NEWS scale. The shortened NEWS is suggested for clinical use due to its predictive power with fewer variables.
