Glasgow Coma Scale (GCS) - eye response scale
GCSEyeRespnsScale
Glasgow Coma Scale (GCS) - Best eye response (E). The GCS is a standardized instrument for assessing the level of consciousness. It evaluates three aspects of responsiveness: eye opening, motor response, verbal response.
GCS Eye Opening
1;2;3;4;Untestable;Unknown;
No eye opening;Eye opening to pain;Eye opening to speech/verbal command;Eyes open spontaneously;Untestable;Unknown;
Alphanumeric
The form related to this CDE is contains CRFs utilized before the study participant/ subject is seen at a hospital for the stroke event and elements related to the emergency medical services (EMS) course. The Glasgow Coma Scale (GCS) and Los Angeles Motor Scale (LAMS) are included to record information about the participant’s/ subject’s neurological impairment prior to being admitted at a hospital. (Examples of CDEs included: Level of EMS Service; Pre-hospital stroke identification screen; and Pre-hospital neurological impairment scale)

Glasgow Coma Scale (GCS) - motor response scale

Glasgow Coma Scale (GCS) - Best motor response (M). The GCS is a standardized instrument for assessing the level of consciousness. It evaluates three aspects of responsiveness: eye opening, motor response, verbal response.

Glasgow Coma Scale (GCS) - verbal response scale
GCSVerbalRspnsScale
Score that describes the participant's verbal response according to the Glasgow Coma Scale (GCS)
GCS Verbal Response
1;2;3;4;5;Untestable;Unknown;
No verbal response/sounds;Incomprehensible sound;Inappropriate words;Confused;Oriented;Untestable;Unknown;
Alphanumeric
This element should be collected along with the other elements from the Glasgow Coma Scale (GCS).
Intubation and severe facial/eye swelling or damage make it impossible to test the verbal and eye responses. In these circumstances, the score is given as 1 with a modifier attached e.g. 'E1c' where 'c' = closed, or 'V1t' where t = tube. A composite might be 'GCS 5tc'. This would mean, for example, eyes closed because of swelling = 1, intubated = 1, leaving a motor score of 3 for 'abnormal flexion'. Often the 1 is left out, so the scale reads Ec or Vt.

Glasgow Coma Scale (GCS) - total score
GCSTotalScore
Glasgow Coma Scale (GCS) - Total Score. The GCS is a standardized instrument for assessing the level of consciousness. It evaluates three aspects of responsiveness: eye opening, motor response, verbal response. The total score is the sum of the scores for the three response types. (3-15)
GCS Total Score
3;4;5;6;7;8;9;10;11;12;13;14;15;Untestable;Unknown;
3;4;5;6;7;8;9;10;11;12;13;14;15;Untestable;Unknown;
Alphanumeric
This element should be collected along with the other elements from the Glasgow Coma Scale (GCS).
The minimum possible score on the GCS is 3 and the maximum possible score is 15.----http://www.glasgowcomascale.org/faq/ ----*Dealing with missing information: There are various different strategies for dealing with information that is missing because of factors interfering with assessment such as those described above. 1.Assess, communicate and make decisions using the remaining components. Although guidelines are often expressed in terms of a total GCS ‘score,’ the trend in whichever of the components (eye, motor or verbal) can be assessed is still valuable. 2.Do not use number ‘1’ to record missing component; use ‘NT’ (Not testable). 3.Do not report a total score when a component is Not Testable because the score will be low and this could be confusing to medical colleagues. This may also imply that the patient is more unwell than they actually are. 4.It is possible using statistical methods to estimate a missing component from the findings in the other components. This is probably more relevant to research than clinical practice.
