AbstractAssessment of level of consciousness is very important in predicting patient's outcome from neurological illness. Glasgow coma scale (GCS) is the most commonly used scale, and Full Outline of UnResponsiveness (FOUR) score is also recently validated as an alternative to GCS in the evaluation of the level of consciousness. We carried out a prospective study in 97 patients aged above 16 years. We measured GCS and FOUR score within 24 h of Intensive Care Unit admission. The mean GCS and the FOUR scores were lower among nonsurvivors than among the survivors and were statistically significant (P < 0.001). Discrimination for GCS and FOUR score was fair with the area under the receiver operating characteristic curve of 0.79 and 0.82, respectively. The cutoff point with best Youden index for GCS and FOUR score was 6.5 each. Below the cutoff point, mortality was higher in both models (P < 0.001). The Hosmer-Lemeshow Chi-square coefficient test showed better calibration with FOUR score than GCS. A positive correlation was seen between the models with Spearman's correlation coefficient of 0.91 (P < 0.001).
