If the EWS is 3 in a single parameter, what action should be taken?

When the Early Warning Score (EWS) is 3 based on a single parameter, the protocol typically dictates that the situation is significant enough to warrant further medical review. Therefore, involving the medical team is essential. This could indicate potential deterioration in the patient's condition that requires immediate attention or intervention.

In such instances, it is crucial to ensure the medical professionals are informed so that they can evaluate the patient, assess the underlying causes of the elevated score, and determine necessary actions—potentially including adjustments in treatment or further diagnostic measures. This proactive communication is vital in maintaining patient safety and ensuring appropriate care is delivered in a timely manner.
