National Early Warning Score (NEWS) 2

NEWS2 is the latest version of the National Early Warning Score (NEWS), first produced in 2012 and updated in December 2017, which advocates a system to standardise the assessment and response to acute illness.

NEWS2 is due for review in 2023.

How NEWS works

The NEWS is based on a simple aggregate scoring system in which a score is allocated to physiological measurements, already recorded in routine practice, when patients present to, or are being monitored in hospital. Six simple physiological parameters form the basis of the scoring system:

  1. respiration rate
  2. oxygen saturation
  3. systolic blood pressure
  4. pulse rate
  5. level of consciousness or new confusion*
  6. temperature.

*The patient has new-onset confusion, disorientation and/or agitation, where previously their mental state was normal – this may be subtle. The patient may respond to questions coherently, but there is some confusion, disorientation and/or agitation. This would score 3 or 4 on the GCS (rather than the normal 5 for verbal response), and scores 3 on the NEWS system.

A score is allocated to each parameter as they are measured, with the magnitude of the score reflecting how extremely the parameter varies from the norm. The score is then aggregated and uplifted by 2 points for people requiring supplemental oxygen to maintain their recommended oxygen saturation.

This is a pragmatic approach, with a key emphasis on system-wide standardisation and the use of physiological parameters that are already routinely measured in NHS hospitals and in prehospital care, recorded on a standardised clinical chart – the NEWS2 chart.

NEWS2 has continued to be evaluated in acute care setting as demonstrated in these papers:

The performance of the National Early Warning Score and National Early Warning Score 2 in hospitalised patients infected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - PubMed (nih.gov)

The early use of sepsis scores to predict respiratory failure and mortality in non-ICU patients with COVID-19 - ScienceDirect

NEWS2 has received formal endorsement from NHS England and NHS Improvement to become the early warning system for identifying acutely ill patients – including those with sepsis – in hospitals in England. To support the safe adoption of NEWS2, NHS Improvement has produced a resource pack.

The NEWS2 Report

Supplementary guidance to support implementation of NEWS 2

The RCP has also produced supplementary guidance to support implementation of NEWS2. Advice is given in five categories – new confusion, escalation/response guidance, oxygen scales, receiving acute patients into hospital, and what to do when the NEWS2 scores are incomplete.

An example of a structured document of clinical response to deterioration can be found here.

NEWS2 and deterioration in COVID-19

This guidance emphasises the place of NEWS2 in managing patients with COVID-19.

NEWS2 should be used when managing patients with COVID 19. The use of NEWS2 will ensure that patients who are deteriorating, or at risk of deteriorating, will have a timely initial assessment by a competent clinical decision maker. NEWS2 should supplement clinical judgement in assessing the patient’s condition.

The NEWS2 scoring system for oxygen supplementation is binary (yes/no). In patients with COVID-19 infection, once hospitalised and treated with oxygen, their oxygen requirement might increase rapidly if their respiratory function deteriorates but this may not result in any additional significant increase in the NEWS2 score. Therefore, in patients with COVID 19, all staff should be aware that ANY increase in oxygen requirements should trigger an escalation call to a competent clinical decision maker. This should be accompanied by an initial increase in observations to at least hourly until a clinical review happens, if this has not already happened as a result of NEWS2.

Use of NEWS2 across the acute care pathway

NEWS2 is increasingly used across the acute care pathway and this is demonstrated in the video below which tells Paul's story - an example of NEWS enabling swift and effective treatment.

    Evaluating local effectiveness of NEWS2

    NEWS2 aims to ensure a rapid response to the deteriorating patient. Internal guidance on measuring the effective implementation locally is given in this paper by the International Society for Rapid Response systems.
