The Extended Glasgow Outcome Scale subdivides 3 levels of the original Glasgow Outcome Scale, thereby extending the number of levels from 5 to 8. This can better categorize patients and is more useful for monitoring patients after severe head injury.
Original Glasgow Outcome Scale |

moderately disabled (MD) |

Limitations:
• Although more levels allow for better discrimination, the allocation may be less consistent (Brooks et al; Maas et al).
• Use of strict criteria and a structured questionnaire (Wilson et al) can improve performance.
Purpose: To use the Extended Glasgow Outcome Scale to describe a patient following severe head injury.
