Activity Summary

Required reading for all learners: Implicit Bias impacts patient outcomes

The Glasgow Coma Scale was developed in 1974 as an injury severity score to assess and predict outcome after traumatic brain injury. The tool is now used to score depth of impaired consciousness in patients with and without traumatic brain injury. However, evidence supporting the use of the Glasgow Coma Scale in the latter group is limited. The Glasgow Coma Scale is not recommended for use in patients without traumatic brain injury; clinicians should use a more appropriate and validated clinical assessment instrument for this patient population.


  • Identify the history and assumptions for using the Glasgow Coma Scale as an assessment for patients with and without traumatic brain injury.
  • List six variables identified as potential confounders in this analysis that were controlled for using a generalized estimating equation.
  • Describe the limitations of using the Glasgow Coma Scale as an assessment tool for patients with stroke.
