NEWS2 Score Calculator

A "Red Score" occurs when any single physiological parameter (such as heart rate or blood pressure) scores a 3. This indicates an extreme abnormality and requires an urgent clinical review, even if the total aggregate score is relatively low.

Patients with hypercapnic respiratory failure (like many with COPD) use "Oxygen Scale 2." This scale has a different weighting for SpO2, recognizing that a lower saturation (88-92%) may be their normal physiological state and that higher saturations could be detrimental.

A score of 5 or 6 is considered "Medium Risk." It is a key trigger threshold that requires an urgent clinical review by a senior clinician (usually at the level of a core trainee or above) and a minimum hourly monitoring check.

ACVPU stands for Alert, Confusion (New), Voice, Pain, Unresponsive. The inclusion of "New Confusion" is a vital addition in NEWS2, as it is often an early indicator of severe illness, sepsis, or neurological deterioration.

While NEWS2 is not a sepsis diagnostic tool, a score of 5 or more is a major trigger for "Think Sepsis." Clinicians are taught that any patient with a NEWS2 of 5+ must be screened for sepsis immediately to ensure early antibiotic administration if needed.

The frequency depends on the score: 12-hourly for a score of 0, 4-6 hourly for scores of 1-4, and at least hourly for scores of 5 or more. Patients scoring 7 or higher should have their vitals monitored continuously.
