Glasgow Coma Scale (GCS):
Loss of Consciousness (LOC):
Statement of the problem: Descriptions and labels of severity of injury are often not terribly informative and sometimes are misleading. Clinical issue: There are a variety of approaches to describing traumatic brain injury (TBI) severity. The most commonly used reported measure, the Glasgow Coma Scale (GCS) does not provide much information for long term prognosis by itself.
Best practice approach: Four common methods used to determine severity of TBI will be presented with detailed descriptions and 'compare and contrast' observations. These include: the GCS, duration of post-traumatic amnesia (PTA), duration of loss of consciousness (LOC) and use of neuroimaging findings (CT, MRI). The utility, advantages, and disadvantages of each will be described. Further research needed will also be addressed.
Post-traumatic Amnesia (PTA):
Brain Injury Severity:
Acute injury severity is determined at the time of the injury, but this does not always accurately reflect later functional outcome.
