to the Glasgow Outcome Scale
Glasgow Outcome Scale (GOS) was commonly used before other scales
were developed. As a brief descriptive outcome scale it has been
replaced by the DRS, although it is still seen occasionally in the
literature, especially in studies investigating early acute medical
predictors of gross outcome. The five categories of the original
scale are: dead, vegetative, severely disabled, moderately disabled,
and good recovery. An extended version of the scale divides each
of the latter three categories in two, making eight categories.

Clara Valley Medical Center. Please contact Dr. Linda Isaac, PhD at
regarding the presented information.
Please note that the GOS has been replaced by the Disability Rating Scale (DRS), and therefore GOS certification is no longer available through the COMBI website. To become DRS certified, please refer to the following link: http://tbims.org/combi/drs/index.html.
