PURPOSE
Two years have passed since a level I trauma center was officially opened in the Gacheon Gil Hospital, South Korea. We analyzed 2014 and 2015 registered patient data from the Korean Trauma Data Base (KTDB) to identify trends in trauma patient care and factors that influence the quality of trauma care at the Gacheon Gil trauma center.
METHODS
Data was extracted from the KTDB included patient age, sex, systolic blood pressure at emergency room arrival, revised trauma score, injury severity score, trauma injury severity score, transfusion amount, and the cause of death was analyzed.
RESULTS
A total of 3269 trauma patients were admitted to our trauma center in 2014 and 3225 in 2015. Demographics and mechanism of injury were not significantly different between years. The severity of trauma injury was decreased in 2015 although the mortality rate was slightly increased. This requires further analysis.
CONCLUSION
The aim of this study was to determine the general status and trends in trauma incidence and management outcomes for the Incheon area. We noted no significant changes in trauma status from 2014 to 2015. We need to collect and review trauma patient data over a long period in order to elucidate trauma incidence and management trends in the trauma field. Finally, studies using trauma patient data will indicate appropriate quality control factors for trauma care and help to improve the quality of trauma management.

PURPOSE
The purpose of this study was to analyze the effectiveness of regional trauma center's management.
METHODS
Data collected between January 2013 and December 2015 from a regional trauma center registry was retrospectively reviewed. The patients who had injury severity score (ISS) greater than 15 and over the age of 18 were included. We compared annual general characteristics, the injury mechanism, the pathway of transportation, the injury severity score, the length of stay in emergency department (ED) and hospital, the in-hospital mortality.
RESULTS
The annual numbers of enrolled patients were 337, 334 and 278, respectively. No significant differences were found in the annual patient's median ages, injury mechanism, ISS and in-hospital mortality. The annual proportions of coming from other hospital and the median length of stay in hospital were increased after establishment of regional trauma center. The annual median lengths of stay in ED were decreased remarkably.
CONCLUSION
Through the establishment of regional trauma center, the length of stay in ED can be reduced but not in-hospital mortality. More multidisciplinary cooperation and well-organized study is needed to reduce mortality of major trauma patients and maximize effect of regional trauma center.

PURPOSE
Traumatic brain injury (TBI) is the most common cause of pediatric trauma patients came to the emergency department. Without guidelines, many of these children underwent repeat brain computed tomography (CT). The purpose of this study was to evaluate the value of repeat brain CT in children with TBI.
METHODS
We conducted a retrospective study of TBI in children younger than 19 years of age who visited the emergency department (ED) from January 2011 to December 2012. According to the Glasgow Coma Scale (GCS) and Pediatric Glasgow Coma Scale score of the patients, study population divided in three groups. Clinical data collected included age, mechanism of injury, type of TBI, and outcome.
RESULTS
A Total 83 children with TBI received repeat brain CT. There were no need for neurosurgical intervention in mild TBI (GCS score 13-15) group who underwent routine repeat CT. 4 patients of mild TBI group, received repeat brain CT due to neurological deterioration, and one patient underwent neurosurgical intervention. Routine repeat CT identified 12 patients with radiographic progression. One patient underwent neurosurgical intervention based on the second brain CT finding, who belonged to the moderate TBI (GCS score 9-12) group.
CONCLUSION
Our study showed that children with mild TBI can be observed without repeat brain CT when there is no evidence of neurologic deterioration. Further study is needed for establish indication for repetition of CT scan in order to avoid unnecessary radiation exposure of children.

Abstract PDF: PURPOSE
Trauma is one of the major cause of death in Korea. This study focused on the survival rate and the neurologic outcome for patients with traumatic cardiac arrest (CA) at one emergency center.
METHODS
We retrospectively reviewed the medical records of patients with traumatic CA who were seen at a regional emergency medical center from January 2010 to December 2011. From among major trauma patients at that medical center, adults older than 18 years of age who had CA were included in this study. CA included out-of-hospital CA with arrival at the Emergency Department (ED) within three hours and in-hospital CA. We checked the survival rate and the neurologic outcome.
RESULTS
A total of 61 patients were analyzed: 32 patients had return of spontaneous circulation (ROSC), 6 patients survived to discharge (survival rate: 9.84%), and 4 were still alive 90 days after discharge. The Cerebral performance category (CPC) scores at 6 months after discharge showed 1 good and 5 poor in neurologic outcomes. Factors such as initial rhythm of CA, part with major injury, Revised Trauma Score (RTS) and pH, were significant for ROSC, survival, and neurologic outcome in patients with traumatic CA.
CONCLUSION
In this study, patients who had traumatic CA showed a 9.84% survival rate and a 1.64% good neurologic outcome. The results are poorer than those for CA caused by disease. Multi-center, prospective studies are needed.; Summary

Abstract PDF: PURPOSE
Hemodynamically unstable pelvic fractures represent therapeutic challenges for the trauma team. The authors of this article have studied the clinical profiles of the angiographic intervention population at the emergency department during four years (2005~2009) to develop clinical guidelines for preventing deaths due to multiple trauma and for predicting the prognosis during initial evaluation.
METHODS
We performed a retrospective review of 34 patients who had undergone angiographic interventions at the emergency department and compared the differences in clinical variables between survivors and non-survivors.
RESULTS
Representative values were compared between survivors and non-survivors : RTS (revised trauma score) 7.006 (6.376~7.841) vs. 6.128 (4.298~6.494), PRC (packed red cell) units 5.5 (2.0~11.0) vs. 15 (8.0~18.5), and lactate (mmol/L) 3.0 (1.0~7.0) vs. 8.5 (3.5~10.5). RTS (p<0.01) and PRC units before angiographic interventions (p=0.01) and lactate (p=0.02) had correlations to the final outcomes.
CONCLUSION
The availability of an angiographic suite and persistent hypotension after adequate fluid resuscitation for pelvic trauma are good indications of angiographic intervention for pelvic hemorrhage.; Summary

Abstract PDF: PURPOSE
To analyze delayed diagnosis, we collected date on pediatric and adolescent patients who had been admitted to the Emergency Department with injuries due to minor trauma METHODS: We retrospectively analyzed the age distribution, trauma mechanism, time interval for each affected body region at delayed diagnosis, hospital stay, and outcome for 161 pediatric and adolescent patients who had been admitted to the Emergent Department of Gachon University Gil Hospital from January 2006 to September 2008.
RESULTS
The incidence of delayed diagnosis in pediatric and adolescent trauma was 11.8% in our retrospective review of 161 pediatric and adolescent patients. Lengths of hospitalization were longer in patients with delayed diagnosis (p<0.05). Patients with delayed diagnosis were more often transferred to other hospitals than patients with non-delayed diagnosis (p<0.05). The time intervals for each different affected body regions at delayed diagnosis were significantly different, but the hospital stays were not. There were no statistical significance to age on affected body region.
CONCLUSION
From this study, we found that admission result and hospital stay were statistically significant differences between the delayed-diagnosis patient group and the non-delayed-diagnosis patient group. Finally, we must follow up pediatric and adolescent patients with minor trauma, closely considering missed injuries.; Summary

Abstract PDF: PURPOSE
A traumatic lung cyst (TLC) is a rare complication and is usually detected with a pulmonary contusion. This study attempted to identify the prognostic factors and the clinical characteristics for pulmonary contusion with TLCs.
METHODS
We retrospectively reviewed the medical records and chest CT findings of 71 TLC patients who visited our hospital from January 2006 to December 2007. Patients were assessed for any clinical characteristics. We evaluated significant differences between the survival and the death groups for patients with a traumatic lung cyst.
RESULTS
The male-to-female ratio of patients with TLCs was 54:17, and the mean age of the patients was 37.70 +/- 19.78 years with 36.6% of the patients being under 30 years fo age. The cause of blunt thoracic trauma was mainly pedestrian traffic accidents (26.8%) and falls (25.4%). Associated conditions included pulmonary contusion in 68 patients (95.7%), hemopneumothorax in 63 patients (88.7%), and rib fracture in 52 patitents (73.2%). There was no consistent relationship between the number of TLCs and the pulmonary contusion score. The overall mortality rate of TLC patients was 26.8%. Death correlated with a need for ventilatory assistance, mean arterial pressure, worst mean arterial pressure in 24 hours, initial pH and base excess, worst pH and base excess in 24 hours, refractory shock, initial GCS score, and pulmonary contusion score.
CONCLUSION
The presence of the aforementioned predictors indicate serious injury, which is the main determinant of the outcome for thoracic injuries with TLCs.; Summary
