The verbal component of the Glasgow Coma Scale does not contribute to a total Glasgow Coma Scale score in mortality prediction among non-intubated encephalopathic individuals.
Why this matters
In people with reduced consciousness, it is important that assessment scales are accurate and easy to administer; although the Glasgow Coma Scale is a widely accepted tool, it is unknown whether the inability to assess verbal response hinders its accuracy. This novel study compared the mortality predictive values of the Glasgow Coma Scale with the Full Outline of UnResponsiveness Score, a scale designed to overcome this barrier.
The observation that the verbal component of the Glasgow Coma Scale does not significantly influence the utility of the total Glasgow Coma Scale score for predicting mortality is particularly important in resource-limited settings in people not considered for mechanical ventilation.
