The GCS Sucks!
The Glasgow Coma Score (GCS) was developed in the 1970s initially as a research tool for admitted Neurosurgery patients. The original authors of the score and research advocated against it’s widespread use in acute care but nevertheless here we are: it is widely used in acute trauma and medical care. Other than a score of 3 or a score of 15, there are multiple combinations of numbers that can get you various scores. This results in a poor ability to know what the patient is actually doing.
