Summary
Key Learning Points
1. The aims are to detect clinical deterioration early in all hospitalised patients.
2. Most NHS hospitals use some form of Early Warning Score (EWS).
3. The Royal College of Physicians (RCP) supports the use of a nationally standardised track and trigger system – the National Early Warning Score (NEWS) 2.
4. The NEWS systems aim to support consistent clinical decision-making.
5. A graded clinical response is triggered, dependent on the score, based on simple physiological parameters and their degree of deviation from the normal values.
