Glasgow Outcome Scale
A standardized scale for assessing functional outcomes in patients following traumatic brain injury or other acute neurological conditions.
Full Definition
The Glasgow Outcome Scale (GOS) is a widely used instrument for evaluating functional recovery and long-term outcomes in patients with traumatic brain injury. The original scale consists of five categories: death, persistent vegetative state, severe disability, moderate disability, and good recovery. An extended version (GOS-E) provides eight categories with finer discrimination. The scale focuses on overall functional capacity rather than specific neurological deficits and is commonly used in clinical trials, outcome research, and rehabilitation planning. Assessment typically occurs at specific time points, most commonly at 6 months and 1 year post-injury.
Usage
Usage note: Distinct from Glasgow Coma Scale (GCS). Editors should verify the correct scale is referenced, as both are commonly abbreviated as 'Glasgow scale.'
