HdBe-GlasgowComaScale

Fifteen-point scale for expressing a person’s level of consciousness, from fully awake to deep unconsciousness, in a number: the so-called EMV score. The Glasgow Coma Scale score or EMV (Eye-Motor-Verbal) score is a scale to measure the extent of consciousness, based on eye, verbal and motor responses to specific prescribed sound and pain stimuli.

Purpose

The GCS score provides the opportunity to document a clinical observation of a patient’s conscious state with a validated instrument which makes use of a patient’s responses to stimuli.

Evidence Base

The Glasgow Coma Scale is used to evaluate a patient’s consciousness by means of three elements:

  1. opening eyes (eye response);

  2. answering questions (verbal response);

  3. motor response.

The three response values are looked at individually and as a whole. The total is referred to as the EMV score. The minimum total score is 3 and the maximum is 15. A slightly altered scale is used for infants (age 0-2) and toddlers (age 2-5).

The EMV score can be expressed as a combination of each of the three individual scores, such as: E3M2V4 (opens eyes when spoken to, arms stretch in response to pain and patient produces incomprehensible sounds). If one of the EMV elements cannot be evaluated - such as might be the case if a patient is intubated and incapable of verbally responding, or is paralyzed/weak and incapable of fulfilling the motor request, then the individual score is included (score NT), with an extra comment. Er moet dan GEEN totaalscore worden doorgegeven. V1T is used for an intubated patient, in which t = 'tube'. Clinical decisions must be based on each of the specific data of the eyes, motor and verbal responses and, if evaluation is not possible, an explicit explanation.

Standard values for the total score, depending on age: 0-6 months : 9 and up 6 months: 10 and up 6-12 months : 11 and up 1-2 : 12 and up 2-5 : 13 and up

5 : 14 and up

GlasgowComaScale.extension
DefinitionMay be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.
