Early Sepsis Detection and Management

Introduction to Sepsis Detection Tools

The National Institute for Health and Care Excellence (NICE) recommends the use of NEWS2 for the initial assessment and repeated monitoring of patients with suspected sepsis, due to its high sensitivity and specificity 1

NEWS demonstrates higher sensitivity for early identification of sepsis compared to SIRS and qSOFA, with a sensitivity of 84-86% versus 86-98% for SIRS and 28-42% for qSOFA 1

The NICE 2024 guidelines specifically recommend the use of NEWS2 for the evaluation and monitoring of patients with suspected sepsis, with a score of ≥7 indicating high risk of severe disease or death from sepsis, requiring evaluation every 30 minutes 1
A score of 5-6 indicates moderate risk, requiring evaluation every hour, while a score of 1-4 indicates low risk, with evaluation every 4-6 hours 1
A score of 3 in any individual parameter may indicate increased risk, regardless of the total score 1

NEWS surpasses qSOFA because it was specifically designed to detect early clinical deterioration, whereas qSOFA was designed to identify high-risk patients, not for screening 2
NEWS uses six easily measurable physiological parameters at the bedside, without requiring laboratory results, allowing for immediate evaluation 1

NEWS also demonstrates superiority in predicting mortality, with an AUROC of 0.95 versus 0.89 for SIRS and 0.87 for qSOFA 1
