Note that this calculator has been updated as of May in order to add more supporting references and to distinguish between the Glasgow Coma Score total score, only applicable when all three components are testable and the Glasgow Coma Scale component scores, applicable if any of three components is not testable.

The Glasgow Coma Scale is an adopted standard for assessment of impaired consciousness and coma in the acutely ill trauma and non-trauma patient and assists with predictions of neurological outcomes complications, impaired recovery and mortality. Please fill out required fields. Bryan Jennett, MD, d. In , he was named Commander of the Order of the British Empire CBE.

To view Dr. Bryan Jennett's publications, visit PubMed. Why did you develop the Glasgow Coma Scale? Was there a clinical experience that inspired you to create this tool for clinicians? A better system of assessment was also needed to support Bryan Jennett's interests in prognosis by relating a patient's early severity to their outcome.

We aimed for a method that would be widely acceptable, covering the spectrum of degrees of injury from many causes — beyond specialist neurosurgical units where only a minority of patients are managed. Are there cases in which it has been applied, interpreted, or used inappropriately? The purpose of the Scale is to describe and communicate the condition of an individual patient by separate, multidimensional rating of their eye, verbal and motor responses.

It remains the appropriate method for this purpose. The Score came a couple of years later. We had assigned numbers to the steps in each response so that they could be readily used in research; the temptation to aggregate the 3 into a total score became irresistible! The total score is very useful as a summary of severity in groups and in classification. It does provide a rough index in an individual but conveys less information than the scale.

If one or other response cannot be assessed, a total score cannot be derived but the information in the remaining responses of the scale can still inform management. Second: the reliability of the scale can be high, but cannot be assumed, nor left to chance. In the course of a review of the scale I became aware that over the years of the emergence of quite wide variations both in how it is assessed and in the level of reproducibility.

Consistent assessment is promoted by training and experience and to support these we have set up a website containing a video setting out a standard, structured approach GlasgowComaScale.

Are there any adjustments or updates you would make to the scale given recent changes in medicine like imaging, or the data and research we now have on concussion? I've often considered the need for changes and am aware of many proposals.

Derivatives from the scale have been described but have reflected limited perspectives. A view that it is too complex has led to an assessment limited to only 3 steps in the motor scale, the Simplified Motor Scale; this may have application in immediate triage in severe injuries but is inadequate for the great majority of patients with lesser injuries.

Views that a more elaborate system incorporating more features is needed, for example in neuro intensive care, overlook that it was always intended that other signs should be assessed, but alongside the scale, not lumped into even more complex scores.

The scale seems still to be valuable in providing a common language across the full spectrum of responsiveness in a wide range of clinical circumstances. I have not been persuaded that changes are appropriate, apart from simplifying and tidying up some of the terms. Assessment of a patient with the scale and the use of other investigations such as imaging have interacting and overlapping places in management. The findings of the scale provide indications for performing imaging, and for then interpreting the clinical implications of its findings.

A scan doesn't tell you what the patient is like. The challenge in working on concussion is the lack of an independent, biologically sound, way of separating it out sharply and definitely within the spectrum of mild, trauma-induced brain disturbances.

Agreement on practical, operational thresholds, perhaps based on degrees and durations of impairment of orientation and eye opening, might help research and clinical care. Other comments? Any new research or papers on this topic in the pipeline? Having developed the tool in , any thoughts on how widespread its use has become even being applied to atraumatic changes in consciousness? The 40th birthday of the scale was the lever used by some colleagues to stimulate me to join them in conducting a thorough review of how it had fared, where it is now and what might be appropriate in future.

org - A web site, based around an instructional video, to promote communication about the scale and good practice in its use. Perhaps the most eloquent confirmation that the scale has found value and widespread acceptance for many purposes came in the finding in a survey, done as part of the review, that it is now used by neurosurgeons in more than 80 countries across the world and has been translated into some 60 languages.

Sir Graham Teasdale, MBBS, is an honorary professor at the Institute of Health and Wellbeing, University of Glasgow. He was previously the professor of neurosurgery, head of the department of neurosurgery, and associate dean for medical research at the University of Glasgow. Sir Teasdale was also the president of the Royal College of Physicians and Surgeons of Glasgow , and was knighted in for his services to neurosurgery.

Attention COACH STUDY participants:. The principal investigators of the study request that you use the official version of the modified score here. Coma severity based on Eye 4 , Verbal 5 , and Motor 6 criteria. When to Use. Why Use. Designed for use in serial assessments of patients with coma from either medical or surgical causes to be widely applicable. In the care of an individual patient, the ratings of the three criteria in the Scale should be assessed, monitored, reported, and communicated separately.

The combined Score is an index of the net severity of impairment and is useful as a summary of a patients condition, in classifying groups of different severity, for triage, and in research. The Score cannot be calculated if one or other of the component criteria is not testable.

The GCS has been shown to have statistical correlation with a broad array of adverse neurologic outcomes, including brain injury, need for neurosurgery, and mortality. The GCS has been incorporated into numerous guidelines and assessment scores e. ACLS, ATLS, APACHE I-III , TRISS and WNS SAH Grading Scale.

In some patients, it may be impossible to assess one or more of the three components of the coma scale.

Verbal: intubation. All eye, verbal, motor : sedation, paralysis, and ventilation eliminating all responses. If a component is untestable, a score of 1 should not be assigned Teasdale In this circumstance, summation of the findings into a total Glasgow Coma Score is invalid. The 3 parts of the Glasgow Coma Scale are charted independently, and the position can be recorded as NT not testable , with an option of indicating the reason, e.

C for eye closure and T for intubation. A GCS of 8 should not be used in isolation to make a determination of whether to intubate a patient, but does suggest a level of obtundation that should be evaluated carefully.

Reproducibility is usually good Reith
