Objective
[edit | edit source]
The Glasgow Coma Scale (GCS) was first created by Graham Teasdale and Bryan Jennett in 1974. It is a clinical scale to assess a patient’s “depth and duration of impaired consciousness and coma”[1] following an acute brain injury. Healthcare practitioners can monitor the motor responsiveness, verbal performance, and eye opening of the patient in the form of a simple chart. The GCS is the most commonly used tool internationally for this assessment and has been translated into 30 languages. It should not, however, be confused with the Glasgow Outcome Scale (GOS), which evaluates persistent disability after brain damage. [2]

Reliability[edit | edit source]
The inter-rater reliabilty of the total Glasgow Coma Scale is p=0.86. Some research has subdivided the inter-rater reliabiltiy for each subscale. For the eye score the inter-rater reliability is p=0.76, the verbal score is p=0.67, and the motor score is p=0.81 [4] The research for test-retest reliability is not recent and should be updated, however the best available evidence is k=0.66-0.77 [5]
Validity[edit | edit source]
The validity of the glascow coma scale comes under fire because a lot of hospitals administer the test while patients have been sedated, often underestimating patient scores. It’s also difficult to elicit accurate scores when patients are intubated
