Emergency Room nurse, ItalyTitle: National Early Warning Score 2 to identify sepsis in the emergency department. A review of the literature
Abstract
Aim: The aim of this study is to understand the
described sensitivity and specificity in the literature
of the score NEWS2 to identify early patients at
developmental risk for sepsis through the use of the
score in the intra-hospital triage phase, comparing
it with the diagnostic accuracy of qSOFA: Quick
Sequential [Sepsis-related] Organ Failure
Assessment for sepsis with organ dysfunction,
infection-related mortality, or ICU due to infection,
especially in patients by priority code level 3, 4,
and 5 as levels 1 and 2 represent absence or rapid
deterioration of one or more vital functions and risk
of impairment of vital functions, respectively.
Materials and Method: The study is based on a
literature review by querying four databases,
including PubMed, Cinahl, Embase, and Cochrane
Library and the Guidelines of the Regional Health
Council of Tuscany Region (2016). The study also
asks a question: Does the use of the NEWS 2 early
warning system in intrahospital triage lead to early
recognition and treatment of patients at high risk
for sepsis?
Result: The NEWS is more accurate in
predicting mortality or ICU admission due to
infection within 72 hours than qSOFA and SIRS in
patients suspected of sepsis at initial presentation
to the emergency department. This will potentially
aid in the early diagnosis of all patients at risk for
ED deterioration, including those at risk for sepsisrelated mortality.
Conclusion: The use of NEWS
2 is important because of the predictive power of
urgent priority, increasing the ability to
discriminate patients who may be worsening their
condition, despite a priori being otherwise
classified. Implementation of the NEWS 2 among
hospital-wide triage procedures effectively predicts
early mortality and detects highrisk patients.
