title: Correlation between Glasgow Coma Scale and brain computed tomography-scan findings in head trauma patients.
abstract: BACKGROUND
  The study aimed to assess the relationship between computed tomography (CT) scan findings and Glasgow Coma Scale (GCS) score with the purpose of introducing GCS scoring system as an acceptable alternative for CT scan to clinically management of brain injuries in head trauma patients.
  
  
  METHODS
  This study was conducted on hospitalized patients with the complaints of head trauma. The severity of the head injury was assessed on admission by the GCS score and categorized as mild, moderate, or severe head injury.
  
  
  RESULTS
  Of all study subjects, 80.5% had GCS 13-15 that among those, 45% had GCS 15. Furthermore, 10.5% had GCS ranged 9-12 and 9% had GCS <8. Of all subjects, 54.5% had abnormal CT findings that of them, 77.1% categorized as mild head injury, 11.0% had a moderate head injury, and 11.9% had a severe head injury. Furthermore, of those with GCS 15, 41.0% had abnormal CT scan. Of all patients with abnormal CT findings, 33.0% underwent surgery that 61.1% categorized in mild head injury group, 13.9% categorized in moderate head injury group, and 22.2% categorized in severe head injury group. Of those with GCS equal to 15, only 27.0% underwent surgery.
  
  
  CONCLUSIONS
  The use of GCS score for assessing the level of injury may not be sufficient and thus considering CT findings as the gold standard, the combination of this scoring system and other applicable scoring systems may be more applicable to stratify brain injury level.
