Analysis of incidence of traumatic brain injury in blunt trauma patients with Glasgow Coma Scale of 12 or less
Purpose: Early diagnosis of traumatic brain injury (TBI) is important for improving survival and neurologic outcome in trauma victims. The purpose of this study was to assess whether Glasgow Coma Scale (GCS) of 12 or less can predict the presence of TBI and the severity of associated injuries in blunt trauma patients. Methods: A retrospective cohort study including 303,435 blunt trauma patients who were transferred from the scene to hospital from 1998 to 2013. The data was obtained from the records of the National Trauma Registry maintained by Israel's National Center for Trauma and Emergency Medicine Research, in the Gertner Institute for Epidemiology and Health Policy Research. All blunt trauma patients with GCS 12 or less were included in this study. Data collected in the registry include age, gender, mechanism of injury, GCS, initial blood pressure, presence of TBI and incidence of associated injuries. Patients younger than 14 years old and trauma victims with GCS 13–15 were excluded from the study. Statistical analysis was performed by using Statistical Analysis Software Version 9.2. Statistical tests performed included Chi-square tests. A p-value less than 0.05 was considered statistically significant. Results: There were 303,435 blunt trauma patients, 8731 (2.9%) of them with GCS of 3–12 that including 6351 (72%) patients with GCS of 3–8 and 2380 (28%) patient with GCS of 9–12. In these 8731 patients with GCS of 3–12, 5372 (61.5%) patients had TBI. There were total 1404 unstable patients in all the blunt trauma patients with GCS of 3–12, 1256 (89%) patients with GCS 3–8, 148 (11%) patients with GCS 9–12. In the 5095 stable blunt trauma patients with GCS 3–8, 32.4% of them had no TBI. The rate in the 2232 stable blunt trauma patients with GCS 9–12 was 50.1%. In the unstable patients with GCS 3–8, 60.5% of them had TBI, and in subgroup of patients with GCS 9–12, only 37.2% suffered from TBI. Conclusion: The utility of a GCS 12 and less is limited in prediction of brain injury in multiple trauma patients. Significant proportion of trauma victims with low GCS had no TBI and their impaired neurological status is related to severe extra-cranial injuries. The findings of this study showed that using of GCS in initial triage and decision making processes in blunt trauma patients needs to be re-evaluated.

Evaluation of differences in injury patterns according to seat position in trauma victims survived traffic accidents
Purpose: Investigation of injury patterns epidemiology among car occupants may help to develop different therapeutic approach according to the seat position. The aim of the study was to evaluate and compare differences in the incidence of serious injuries, between occupants in different locations in private cars. Methods: A retrospective study including trauma patients who were involved in motor vehicle accidents and admitted alive to 20 hospitals (6 level â… trauma centers and 14 level â…ˇ trauma centers). We examined the incidence of injures with abbreviated injury score 3 and more, and compared their occurrence between seat locations. Results: The study included 28,653 trauma patients, drivers account for 60.8% (17,417). Front passenger mortality was 0.47% higher than in drivers. Rear seat passengers were at greater risk (10.26%) for traumatic brain injuries than front seat passengers (7.48%) and drivers (7.01%). Drivers are less likely to suffer from serious abdominal injuries (3.84%) compared to the passengers (front passengers - 5.91%, rear passengers – 5.46%). Conclusion: Out of victims who arrived alive to the hospital, highest mortality was found in front seat passengers. The rate of serious chest injuries was higher as well. Rear seat passengers are at greater risk for serious traumatic brain injuries. All passengers have a greater incidence of abdominal injuries. These findings need to be addressed in order to develop “customized” therapeutic policy in trauma victims. Keywords: Traffic accidents, Injury pattern, Seat positio
