Glasgow Coma Scale Motor Component
Kupas, D.F., Melnychuk, E.M., and Young, A.J. (2016). Glasgow Coma Scale Motor Component ("Patient Does Not Follow Commands") Performs Similarly to Total Glasgow Coma Scale in Predicting Severe Injury in Trauma Patients. Annals of Emergency Medicine. 68(6):744-750.e3.
The authors conducted a retrospective analysis of a statewide trauma registry including records from 393,877 patients from 1999 to 2013 to compare the predictive ability of a total Glasgow Coma Scale (GCS) =13 vs. a Glasgow Coma Scale motor component (GCS-m) <6 for 6 trauma outcomes: Injury Severity Score (ISS) greater than 15; ISS greater than 24; death; ICU admission; need for surgery; or need for craniotomy. They concluded that the GCS-m predicts serious outcomes as well as the total GCS, and its use would simplify triage in the field.
