Abstract

Background: The most powerful independent prognostic variables were GCS and CT characteristics. Since the introduction of CT imaging, the treatment of patients with head injury has improved considerably and it has become a powerful prognostic tool for improving clinical care in TBI, significantly reducing both morbidity and mortality.
Aim of study: To assess the validity of Glasgow Coma Scale and brain computed tomography scan together in predicting outcome of patients presented with traumatic brain injury at emergency department.
Patients and methods: A prospective follow up study carried out in Emergency Department of Baghdad Teaching Hospital in Baghdad Medical city for period from 1st of October, 2015 to 30th of September, 2016 on convenient sample of 244 patients with traumatic brain injury. The diagnosis of traumatic brain injury was based on New Orleans Criteria and Canadian Diagnostic Rules and confirmed by Neurosurgery physician. Glasgow coma scale was measured by researcher and interpretation of Glasgow coma scale was done by both researcher and Neurosurgery physician according to Glasgow Coma Score and computerized tomography scan was interpreted by Radiologist.
Results: The validity results of Glasgow coma scale regarding traumatic brain injury patients' outcome were sensitivity (100%) and specificity (58.9%), while validity results of computerized tomography scan findings regarding traumatic brain injury patients' outcome were sensitivity (66.6%) and specificity (93.6%). The validity results of Glasgow coma scale findings regarding traumatic brain injury patients' morbidity were sensitivity (70.5%) and specificity (99%), while validity results of computerized tomography scan findings regarding traumatic brain injury patients' morbidity were sensitivity (77.7%) and specificity (99%).
Conclusions: The use of both Glasgow coma scale and computerized tomography scan emergency department had valuable results in prediction of morbidity for patients with traumatic brain injury while have no effect for prediction of mortality.
