In what situation must a physician be notified regarding NIHSS score changes?

A physician must be notified when there is a significant change in the NIHSS (National Institutes of Health Stroke Scale) score, which is used to assess the severity of stroke. A change that indicates a worsening of a patient's condition is critical for timely intervention.

In this context, a +2 increase from the last NIHSS score signifies a meaningful deterioration in neurological function. Such changes can indicate the potential for increased stroke severity, complications, or another event that requires immediate medical evaluation and intervention.

This level of change (a +2 increase) underscores the need for rapid clinical assessment and possible treatment adjustments, which align with the protocols for managing stroke patients effectively. Monitoring NIHSS scores is vital, and increases of this magnitude warrant a physician's review to ensure appropriate management of the patient's condition.
