What Is the National Early Warning Score?
The National Early Warning Score, known as NEWS2, is a standardised tool used across the NHS to detect when a patient's condition is deteriorating. It assigns a score based on six key physiological measurements β giving clinicians a clear, objective picture of how unwell a patient is at any given moment.
NEWS2 was developed by the Royal College of Physicians (RCP) and is now mandated across NHS England for use in acute hospital settings. It replaced the original NEWS chart in 2017, with the main addition being an alert for patients at risk of hypercapnic respiratory failure (Type 2 RF) β particularly relevant for patients with COPD.
NEWS2 is not a diagnostic tool. It tells you how unwell someone is, not why. Think of it as an early warning system β it flags the need for clinical review and intervention before a patient crashes.
Respiratory rate, oxygen saturation, blood pressure, pulse rate, level of consciousness, and temperature.
Each parameter is scored 0β3 based on how far it deviates from the normal range.
Mandated across NHS England. Endorsed by NICE and the Royal College of Physicians.
Higher scores trigger escalating clinical responses β from increased monitoring to emergency intervention.
Why Is It Used?
Patient deterioration doesn't happen suddenly out of nowhere. In most cases, there are warning signs hours before a serious event such as cardiac arrest, septic shock, or respiratory failure. The problem is these signs can be subtle and easy to miss β especially on a busy ward.
NEWS2 exists to make sure early warning signs are noticed, recorded, and acted on consistently and promptly, regardless of which ward or hospital the patient is in.
Identifies deteriorating patients before they become critically unwell, allowing earlier intervention.
Gives every NHS clinician a shared language to communicate severity of illness quickly and clearly.
Validated through large-scale research β higher NEWS2 scores correlate with increased mortality risk.
Early escalation saves lives. Sepsis outcomes worsen significantly with every hour of delayed treatment.
NEWS2 is one tool among many. Always use clinical judgement alongside the score. A patient can be very unwell with a low score if their baseline is abnormal β always consider the whole picture.
Where Is It Used?
NEWS2 was originally designed for acute hospital inpatients but its use has expanded significantly. It is now used in virtually every clinical setting where patients are assessed.
During the COVID-19 pandemic, NHS England recommended NEWS2 as the preferred monitoring tool for COVID-19 patients, further cementing its role as the gold-standard early warning system across all settings.
The NEWS2 Scoring Chart
Each of the six physiological parameters is measured and given a score based on how far the value falls outside the normal range. Scores are added together to give a total NEWS2 score. There is also a bonus point added for patients requiring supplemental oxygen.

* ACVPU: Confusion (new), Voice, Pain, Unresponsive β any response other than Alert scores 3. Scale 2 SpOβ is used only for patients with confirmed hypercapnic respiratory failure. Always follow your trust's chart and local policy.
How to Fill Out the NEWS2 Chart
Filling out the NEWS2 chart correctly is a fundamental clinical skill. Here's how to approach it in a clear, structured way.
Before recording anything, check whether the patient has a documented diagnosis of hypercapnic respiratory failure (e.g. COPD with Type 2 RF). If yes, use Scale 2. All other patients use Scale 1. This is documented in the patient's notes or on the chart itself. Getting this wrong significantly affects the total score.
Take and document: respiratory rate (count breaths for a full 60 seconds), SpOβ via pulse oximeter, systolic blood pressure, pulse rate, temperature, and level of consciousness using ACVPU. Note whether the patient requires supplemental oxygen.
Using the scoring chart, find the column matching each recorded value and write down the corresponding score (0, 1, 2, or 3). Add 2 points if the patient needs supplemental oxygen to maintain their target saturation.
Add up all individual parameter scores. The total can range from 0 to a maximum of 20. This aggregate score determines the level of clinical response required.
Even if the aggregate score is low, a single parameter scoring 3 (a "red score") requires an urgent clinical review regardless of the total. This is an important safety net β never overlook a red score.
Match the total score to the appropriate clinical response level (see below). Document your actions and escalation in the patient's notes. Adjust monitoring frequency as required by your trust policy.
A β Alert (score 0) Β |Β C β New Confusion (score 3) Β |Β V β Responds to Voice (score 3) Β |Β P β Responds to Pain (score 3) Β |Β U β Unresponsive (score 3). New confusion is always a significant finding.
Understanding Clinical Response Levels
The total NEWS2 score determines the clinical response required. Always follow your local trust escalation policy β the national framework is as follows:
| 0β4 | Low Risk β Ward-Based ResponseMinimum 12-hourly observations. Nurse in charge to be informed if score is 3β4. Clinical review by the ward-based team. |
| 3 single red |
Low-Medium Risk β Urgent Ward ReviewAny single parameter scoring 3 requires urgent review by a clinician, regardless of the total score. Increase monitoring frequency. |
| 5β6 | Medium Risk β Key ThresholdUrgent response by a nurse or doctor trained in acute illness assessment. Consider transfer to a higher-care environment. Continuous monitoring where possible. |
| β₯7 | High Risk β Emergency ResponseImmediate emergency response. Continuous monitoring. Likely need for critical care involvement. Senior clinical assessment required without delay. |
Think of NEWS2 like a traffic light with extra nuance. A total of 0 is green. A single parameter scoring 3 is a red light β regardless of everything else, it needs attention now. The higher the total, the more urgent the response. Practice completing the chart during simulation before using it clinically.
Things to Remember
Record every observation and score, including time, who was informed, and what action was taken.
A score rising from 1 to 4 over 4 hours is more concerning than a stable score of 4. Trend matters.
Use SBAR (Situation, Background, Assessment, Recommendation) when escalating a NEWS2 concern.
If something doesn't feel right, escalate regardless of score. NEWS2 supports β not replaces β your judgement.
