Background: Glasgow coma score (GCS) are widely used as primary diagnostic tool in trauma cases. In literature study of GCS is seen to be addressed in specific trauma context such as traumatic brain injury, ischemic trauma, and neurotrauma. GCS score on admission is said to be associated with survival of trauma patients. Aims: This study aims to evaluate the efficacy of GCS and its components, eye, verbal, and motor response in all types of trauma in multicenter trauma database in India. Settings: Towards Improved Trauma Care Outcome (TITCO) registry conducted in four city government hospitals in India. Materials and Methods: TITCO database contains information of 16,047 patients, we included 13,836 patients with valid GCS and its components score in this study. The total GCS score is classified as mild (>12), moderate (9–12), and severe (<9). Logistic regression is applied considering GCS and components as independent with overall mortality as a dependent variable. Receivers operating characteristic (ROC) curve is drawn to evaluate the efficacy of GCS and components. Results: Compared to severe GCS score, moderate and mild GCS score is found to have better chances of survival with odds of 6.45 and 17.25, respectively. Similar results are found to be replicated in cases eye, verbal, and motor response. Motor component appeared as a better predictor than eye and verbal response. Area under the curve of ROC was 0.813, 0.775, 0.791, and 0.798 for GCS total, eye, verbal, and motor response, respectively. Conclusions: GCS and components are appeared as the best indicator of predicting overall mortality in all the trauma cases.
