Calculate NEWS2 scores to determine an adult’s risk of severe illness or death from sepsis in acute hospital, mental health, and ambulance settings
Use the person’s risk level to help determine the time window in which to give antibiotics
Sepsis is defined as life threatening organ dysfunction caused by a dysregulated host response to infection.1 In 2016, the National Institute for Health and Care Excellence (NICE) first published guidance on recognising, diagnosing, and managing suspected sepsis. In May 2022, a statement published by the Academy of Medical Royal Colleges2 (and endorsed by NHS England) on use of the updated National Early Warning Score (NEWS2)3 sought to guide the urgency of antibiotic prescribing and source control. The statement was based on a narrative review of the literature and expert clinical consensus.
As a result, in January 2024, NICE guidance was updated to include NEWS2 for stratifying risk of severe illness or death from sepsis.4 The updated guideline aims to ensure that early recognition of patient deterioration and treatment for sepsis becomes standardised nationally, and includes recommendations on the timing of antibiotic prescribing based on a person’s risk level, while investigating the underlying infection source.
NICE recommendations are based on systematic reviews of best available evidence and explicit consideration of cost effectiveness. When minimal evidence is available, recommendations are based on the guideline committee’s expertise and opinion of what constitutes good practice. A subsequent consultation process with stakeholder bodies provides external confirmation. Evidence levels for the recommendations are given in italic in square brackets.
High certainty—we are very confident that the true effect lies close to that of the estimate of the effect.
Moderate certainty—we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there …
