  • Title: Poor relation between Glasgow coma scale and survival after head injury.
    Author: Matis GK, Birbilis TA.
    Journal: Med Sci Monit; 2009 Feb; 15(2):CR62-65. PubMed ID: 19179969.
    Abstract:
    BACKGROUND: Early indicators or predictors of outcome after head injury can affect clinical decision making and the choice of case-specific approaches to rehabilitation. MATERIAL/METHODS: A retrospective study of 60 patients with a head injury who had been admitted to a tertiary care hospital intensive care unit was undertaken to explore the possible correlations between the Glasgow Coma Scale (GCS) and outcome. The correlation among the GCS, GCS eye (GCS-E), GCS verbal (GCS-V), and GCS motor (GCS-M) components and outcome (survival or death) was assessed by constructing contingency Tables and performing the Pearson chi2 and likelihood ratio tests. The statistical significance was set at a P value of 0.05. RESULTS: The mean total GCS score was 6.39+/-0.554 (6.81+/-0.983 for survivors and 5.55+/-0.706 for nonsurvivors). The most frequent GCS score, which was 3 (61.67%), was followed by scores of 15 and 14 (10% and 6.7%, respectively). No correlation was found between outcome and the GCS, GCS-E, GCS-V, or GCS-M components. CONCLUSIONS: Our results suggest that the GCS has a limited predictive value of outcome in patients with a head injury, particularly if used as sole predictor or in patients with a mild-to-moderately severe injury.
