The National Early Warning Score 2 (NEWS2) Overview

The National Early Warning Score 2 (NEWS2) is an updated version of the NEWS system designed to standardize the assessment of patients' vital signs and prompt early intervention when signs of deterioration are detected. NEWS2 incorporates additional parameters compared to the original NEWS system. The parameters assessed in NEWS2 include:

  1. Respiratory Rate: NEWS2 assigns a score based on the respiratory rate per minute, considering both the absolute value and any increase from the patient's baseline. Higher scores indicate abnormal or escalating respiratory rates that may indicate respiratory distress.

  2. Oxygen Saturation: This parameter measures the amount of oxygen carried by hemoglobin in the blood. NEWS2 assigns scores based on the recorded oxygen saturation level and the supplemental oxygen requirement. Lower scores reflect hypoxia or decreased oxygen levels.

  3. Systolic Blood Pressure: The systolic blood pressure is the top number in a blood pressure reading. NEWS2 provides scores based on the recorded systolic blood pressure and considers any changes from the patient's baseline. Lower scores reflect hypotension or low blood pressure.

  4. Heart Rate: NEWS2 evaluates the heart rate and assigns scores based on the recorded values and any deviation from the patient's baseline. Higher scores indicate tachycardia, which can be a sign of stress, infection, or other underlying issues.

  5. Level of Consciousness: NEWS2 includes an assessment of the patient's mental status using the Alert, Voice, Pain, Unresponsive (AVPU) scale or Glasgow Coma Scale (GCS). Changes in the level of consciousness or altered mental status are crucial indicators of neurological compromise.

  6. Temperature: Abnormal body temperature, either elevated or reduced, is assessed in NEWS2. Deviations from the normal range may indicate underlying infection or systemic dysfunction.

  7. New Supplemental Oxygen: NEWS2 includes the assessment of new supplemental oxygen requirements, reflecting the patient's respiratory status and the need for respiratory support.

By combining the scores from each parameter, a total NEWS2 score is obtained. Higher NEWS2 scores indicate a higher risk of deterioration and the need for urgent medical attention.

Interpretation of the National Early Warning Score 2 (NEWS2)

The interpretation of the National Early Warning Score 2 (NEWS2) results depends on the specific thresholds and guidelines set by the healthcare facility or healthcare provider. Generally, higher NEWS2 scores indicate a higher risk of clinical deterioration and may prompt the need for urgent medical attention or closer monitoring.

The exact interpretation and corresponding actions for each NEWS2 score can vary, but here is a general guideline:

  • NEWS2 Score 0 to 4: Low risk - The patient is considered stable, and routine care can continue.
  • NEWS2 Score 5 to 6: Medium risk - The patient may require closer observation and further assessment.
  • NEWS2 Score 7 or higher: High risk - The patient is at significant risk of deterioration and may require urgent medical intervention, escalation of care, or transfer to a higher level of care.

It's important to note that NEWS2 is not a definitive diagnostic tool, but rather a screening tool that helps identify patients who may need further evaluation or intervention. The specific actions triggered by NEWS2 scores may include more frequent monitoring of vital signs, additional investigations, involvement of specialized healthcare providers, or a reassessment of the patient's treatment plan.

It is crucial for healthcare professionals to consider the NEWS2 score in the context of the patient's overall clinical condition, medical history, and any other relevant factors. Clinical judgment and communication among healthcare team members are essential for appropriate management based on the NEWS2 results.

Please note that the interpretation of NEWS2 scores may vary depending on the specific guidelines and protocols followed by the healthcare facility or healthcare provider. It is always best to consult with a healthcare professional familiar with your specific situation for an accurate interpretation and appropriate management.
