NEWS2 Calculator

The National Early Warning Score 2 (NEWS2) is a standardised approach to assessing acute illness severity based on routine vital sign observations. Developed by the Royal College of Physicians (UK), it uses six physiological parameters plus supplemental oxygen status to generate an aggregate score that indicates clinical deterioration risk.

NEWS2 provides a common language for communicating patient acuity across healthcare teams and supports timely escalation of care for deteriorating patients.

Seven parameters are scored:

Respiration rate: 0-3 points SpO2 (Scale 1 or Scale 2): 0-3 points Air or oxygen: 0 or 2 points Systolic blood pressure: 0-3 points Pulse: 0-3 points Consciousness (ACVPU): 0 or 3 points Temperature: 0-3 points

Aggregate score interpretation: 0: Low risk — routine monitoring 1-4: Low risk — assess if increased monitoring needed 5-6: Medium risk — urgent response threshold 7+: High risk — emergency response threshold

Important: A score of 3 in any single parameter should also trigger an urgent clinical response regardless of the total.

NEWS2 is used on hospital wards, in emergency departments, and increasingly in pre-hospital and community settings. It standardises the recording and response to vital signs, reducing variability in how clinical deterioration is identified and escalated.

The score drives escalation protocols — defining who should be informed, how quickly they should respond, and what level of clinical competency is required for the response.

NEWS2 is used in many Australian hospitals, particularly in Victoria and in private hospital networks. It coexists with state-specific systems such as Between the Flags (NSW) and Q-ADDS (Queensland).
