Objectives To explore the traffic injury patients' experience on health care utilization of Korean Medicine (KM) practice and perception of health care system for developing a Korean medicine clinical practice guideline (CPG) of traffic injuries by survey method. Methods Two hundred ten patients in suffering from traffic injuries were surveyed from September 1st, 2019 to January 31th, 2020 at 2 University Hospitals (Pusan National Korean Medicine Hospital and Kyung Hee Korean Medicine Hospital at Gangdong) and 1 Spine Specialty Hospital (Jaseng Hospital of Korean Medicine). A structured questionnaire of experience on health care utilization of KM practice and perception of health care system of was distributed to responders by visits and all data were statistically analysed. Results Survey results showed high satisfaction of patients with the experience of KM treatments in order of daoyin exercise (7.8±2.3), chuna manual therapy (7.7±4.0), pharmacoacupuncture (7.4±3.0) etc. Safety concerns were reported in 9.1% subjects and 205 (97.6%) patients answered that collaboration with KM and western medicine is necessary for patients with traffic injuries. For the patients' requirement for extending insurance coverage, the most required therapy was chuna manual therapy (57.5%) and pharmacoacupuncture (42.0%). Conclusions This study presented the realistic patient-centered perception of KM practice and health care system in Korea. These results will provide basic data to be reflected in the process of adaptation for the revision of Korean Medicine CPG for traffic injuries.

Purpose: Vascular injuries caused by traffic, industrial accidents and by outside activities have increased in Korea. Especially, vascular injuries to the extremities can lead to limb loss and even mortality if they are not appropriately treated. The aim of the study was to evaluate the surgical outcomes of femoropopliteal vascular management after trauma. Methods: The medical records of 12 patients with femoropopliteal vascular injuries who were treated at Dankook University Hospital from 2011 to 2013 were reviewed. Iatrogenic vascular injuries were excluded. The clinical data including the causes of injury, associated injuries and surgical outcomes were analyzed retrospectively. Results: All patients were male, with a mean age of $46.8{\pm}16.3years$ (range: 26~69 years). The causes of vascular injuries were four traffic accidents, three industrial accidents, two iron plates, one outside activity, one glass injury and one knife injury. The average transit time between the place of the accident place and the emergency department was $3.0{\pm}2.1$ (0.5~12.5) hours, and the average preparation time for surgery was $8.0{\pm}6.7$ (1.7~23.3) hours. The anatomic injuries included the popliteal vessel in seven cases and the femoral vessel in five cases. The average Injury Severity Score (ISS) was $12.0{\pm}5.0$ (5~17), and the average Mangled Extremity Severity Score (MESS) was $5.7{\pm}2.1$ (2~9). The operation methods were four interposition grafts, three end-to-end anastomoses, two direct repairs and three patch angioplasties. One case required amputation of the injured extremity. Conclusion: Early recognition and revascularization of the injured vessel are mandatory to reduce limb loss and to obtain satisfactory outcomes. Therefore, careful/rapid evaluation of the vascular injuries and timely/successful surgical treatment are the keys to salvaging an injured limb.

Purpose: Studies on the relationship between obesity and injuries, especially those sustained in pedestrian traffic accidents, are lacking. We aimed to assess the effects of obesity on the severity of injury at the time of admission to the emergency room in patients who experienced pedestrian traffic accidents. Methods: This study included trauma patients registered in the Korean Trauma Database from July 1, 2018 to December 31, 2020, whose mechanism of injury was pedestrian traffic accidents and who were treated at a single institution. Those aged below 15 years were excluded. Patients were assigned to nonobese and obese groups based on a body mass index of 25 kg/m². An Injury Severity Score of 25 or greater was considered to indicate a critical injury. Results: In total, 679 cases of pedestrian traffic accidents were registered during the study period, and 543 patients were included in the final analysis. Of them, 360 patients (66.3%) and 183 patients (33.7%) were categorized as nonobese and obese, respectively. The median age was significantly higher in the nonobese group than in the obese group (60 vs. 58 years). Multivariate analysis demonstrated that the odds ratio for critical injury in obese patients was 1.59 (95% confidence interval, 1.01-2.48) compared with nonobese patients. Conclusions: Obesity affected the likelihood of sustaining severe injuries in pedestrian traffic accidents. Future studies should analyze the effects of body mass index on the pattern and severity of injuries in patients with more diverse injury mechanisms using large-scale data.

The main causes of traffic accidents can be classified by 3 factors - human error, vehicle deficiency and road environmental problem and most accidents occurs not only 1 factor but combination of 2 or 3-factors. Among these factors, road environmental factor is the most important factor due to influence the behavior of cars and road users and road environmental factor affects 30% of total accidents approximately. The 5 years traffic accidents data analyzed to verify the accidents severity on Korea National Highways. In order to analyze the severity, Ordered Probit Model was used. As a independent variables of this model the number of lane, neighbor road environments, sight distance, vertical grade, lane width, shoulder width and traffic volume were used and as a dependent variables the minor injuries, serious injuries and fatalities were used. Research results shows that sight distance and lane width are identified as significant factors for the traffic accident severity and lesser sight distance and lane width shows greater traffic accident severity.

Background: The first 3 ribs are anatomically well-protected, shielded by the large thoracic muscles, the shoulder girdle, and the arm. A significant force is required to fracture these ribs; thus, such fractures suggest a high-energy trauma and are associated with injuries to vital organs of the thorax, such as the aorta, the heart, the lungs and the great vessels. Methods: A retrospective analysis was conducted over a 10-year period at a single hospital. The study assessed patients with fractures of the second rib, including their concurrent injuries and the overall severity of their trauma. Results: Among the 76 patients included in the study, the average age was 47.35 years, 81.5% were men, and 19.5% were women. Thirteen patients (17.1%) survived their injuries. The most common causes of injury were road traffic accidents (63%) and pedestrian injuries (22%). The patients who did not survive sustained injuries to an average of 5 additional organs, while survivors had injuries to an average of 2.07 additional organs. Left rib fractures were the most frequently observed (46%). The most serious concurrent injuries reported were to the aorta (5.26%), heart (10.52%), lung (52.36%), head (57.89%), liver (30.2%), spleen (26.31%), and kidney (17.1%). Conclusion: As indicators of serious injury to vital endothoracic organs, isolated fractures of the second rib should be considered equal to first rib fractures in clinical importance.

Purpose: To compare injury sustained and severity of child occupant according to the types of safety restraint systems in motor vehicle crashes. Methods: This was a retrospective observational study. The study subjects were child occupants under the age of 8 years who visited a local emergency center following a motor vehicle crash from 2010 to 2014. According to safety restraint: child restraint systems (CRS), belted, and unbelted, we compared injuries sustained and injury severity using the maximal Abbreviated Injury Scale (MAIS) and Injury Severity Score (ISS), and analyzed the characteristics of severe injuries (AIS2+). Results: Among 241 subjects, 9.1% were restrained in CRS, 14.5% were only belted, and 76.3% was unbelted at the time of the crashes. Fourteen had severe injuries (AIS2+), all of whom didn't be restrained by CRS. Injuries in face and neck were the highest in unbelted group, and MAIS and ISS were the lowest in CRS group. Conclusion: Among safety restraint systems for child occupant in motor vehicle crashes, the CRS have the preventive effect of face and neck injuries, and are the most effective safety restraint systems.

Purpose: The purpose of the study was to investigate the correlation between injury and injury severity score (ISS) in geriatric traffic accident patients transported by 119 emergency medical technicians (EMTs). Methods: The subjects were 240 traffic accident patients over 65 years old transported by 119 rescue services emergency departments in Busan from January 1, 2014 to August 31, 2015. Results: ISS increased in motorcycle traffic accidents (p=.026), truck injuries (p=.005), and head and neck injury (p<.001). Vital signs were evaluated by 119 rescue EMT. ISS increased in cases of unresponsive unconsciousness (p<.001), hypotension (p=.001), and bradycardia (p<.001). The need for bleeding control and dressing by the EMTs increased ISS significantly (p=.022). Conclusion: In the initial evaluation of geriatric traffic patients, ISS can increase in motor cycle accidents and truck injuries. Due to high ISS, patients with head and neck injury, chest injury, hypotension, or tachycardia should be transferred to advanced level hospitals.

본 논문에서는 개입모형(intervention model)을 이용하여 경부고속도로(천안IC-양재IC) 구간의 최고 제한속도 상향 조정으로 인한 교통사고 발생의 영향을 분석하고자 하였다. 또한 천안IC-양재IC 구간과 부산IC-천안IC 구간의 차이를 이용하여 제한속도의 상향조정 효과를 분석하여 외부적 요인의 영향을 고려하지 않을 경우 제한속도 조정으로 인한 교통사고의 변화를 분석하였다. 그 결과, 제한속도 상향 후 교통 사고발생건수와 사고부상자수는 모두 증가하는 추세이며 특히 최고속도가 예전과 변화 없는 구간에 비교할 때 그 증가 추세는 더 심각한 것으로 판단된다.
