National Early Warning Score 2 NEWS2

The National Early Warning Score (NEWS) has been updated, and is now NEWS2. NEWS2 is still based on a simple aggregate scoring system in which a score is allocated to six physiological measurements. The score includes:

  • Respiratory rate
  • Oxygen saturations *
  • Systolic blood pressure
  • Pulse rate
  • Level of consciousness or new confusion **
  • Temperature

*For patients with hypercapnic respiratory failure who have clinically recommended saturations 88-92%, the chart has a dedicated section (SpO2 Scale 2). Clinicians should score saturations using Scale 1, unless these circumstances apply.

**AVPU is replaced by ACVPU (where C is confusion). Please note that new-onset confusion (including disorientation, agitation or altered mentation) may be subtle in patients who previously had a normal mental state, as the patient may still be able to respond to questions coherently.
