Glasgow Coma Scale
The Glasgow Coma Scale (GCS) (, ) is a commmon neurological assessment scale used to quantify the level of consciousness in a person following a traumatic brain injury. Basically, it is used to help gauge the severity of an acute brain injury.
- The Glasgow Coma Score is also used as part of the APACHE II assessment score for Critical Care Program and the ALERT Scale for Medicine Program.
- The bedside nurses doing the GCS evaluation on the patient will record the best response.
- The data collector will enter the GCS as per Selection and timing of APACHE components
Special notes regarding sedated patients:
- If a pt is an overdose, use the worst score because the sedative effect and the potential injury to the brain due to the drug overdose is part of the acuity score.
- If a pt is heavily sedated, a GCS is not considered accurate, therefore, if possible, use the worst GCS done when the pt. is not on sedation in the first 24 hours.
- If a non-sedated GCS is unavailable in the first 24 hours, use the previous un-sedated GCS if possible.
- If there is absolutely no un-sedated GCS available (e.g. Lost/missing chart), default to a normal GCS.
The below are only meant to help you use your judgement keeping in mind that the purpose of the GCS is to assess the severity of a brain injury, within the first 24hrs of admission.
Patients with normally limited communication ability
For patients whose ability to communicate are reduced due to pre-existing conditions, score as fully functioning if they are able to function at the level that is normal for this patient. (e.g. Down's syndrome)
Patients who fail assessments for reasons other than consciousness
Patients who are aphasic or intubated but clearly can communicate in writing should be coded as functioning normally. Same is true for patients whose eyes are swollen shut etc.

- The list sorting numbers for this one are opposite to scoring
It is the most common scoring system used to describe the level of consciousness in a person following a traumatic brain injury. Basically, it is used to help gauge the severity of an acute brain injury.
