An injury severity scale for comprehensive management of central nervous system trauma.

The Glasgow Coma Scale (GCS) is used in central Virginia by emergency medical technicians (EMT's), emergency department personnel and neurosurgical staff to evaluate patients with central nervous system (CNS) trauma. In a series of 406 patients admitted to the neurosurgical services at the University of Virgina Hospital between October 1977 and February 1978, a GCS score was recorded by the neurosurgeon, nurse, and EMT. All 250 data points, including clinical diagnosis and incidence of associated injuries were entered into our information system analysis. The scale can be easily mastered by all members of the emergency medical team giving reproducible results. It also appears to be a valid predictor of the ultimate outcomes of head injury. The GCS has substantial clinical value in the management of the nuerotrauma patient. It is presently being employed in all phases of the emergency medical system to monitor the progression of the neurologic injury. Ultimately, this injury severity scoring system will be used to standardize patient populations in well controlled clinical studies in which different treatment parameters will be assessed.
