The Edinburgh Extended Glasgow Outcome Scale (EEGOS): rationale and pilot studies
1Rehabilitation Studies Unit, Astley Ainslie Hospital, Edinburgh, UK.
Summary
The Edinburgh Extended Glasgow Outcome Scale (EEGOS) offers a more detailed assessment of recovery after head injury compared to the standard Glasgow Outcome Scale (GOS). Pilot studies show EEGOS has comparable inter-rater reliability to GOS.
Area of Science:
- Neuroscience
- Clinical Neurology
- Rehabilitation Medicine
Background:
- The Glasgow Outcome Scale (GOS) is a standard but limited measure for head injury outcomes.
- GOS lacks sensitivity in detailing specific functional impairments (behavioral, cognitive, physical).
Purpose of the Study:
- To introduce and evaluate the Edinburgh Extended Glasgow Outcome Scale (EEGOS).
- EEGOS aims to provide a more granular assessment of recovery patterns post-head injury.
- To compare EEGOS reliability with the existing GOS.
Main Methods:
- Pilot studies were conducted using the EEGOS.
- The scale was tested retrospectively and via live, face-to-face interviews.
- Inter-rater reliability was assessed by calculating raw percentage agreements.
Main Results:
- Retrospective study yielded agreements of 45%, 60%, and 70%.
- Live interview study showed higher agreements: 83%, 78%, and 83%.
- EEGOS demonstrated reliability comparable to GOS in similar settings.
Conclusions:
- The EEGOS is a reliable outcome measure for head injury research.
- EEGOS provides a more detailed functional assessment than GOS.
- This scale facilitates comparison of recovery patterns across different functional domains.
