노인인구의 증가로 노인운전자의 손상과 사망자도 증가하였다. 하지만 노인운전자의 손상과 중증도에 대한 연구는 활발히 이루어지지 않아 영향 요인을 파악하지 못하고 있다. 본 연구에서는 정면충돌에서의 노인운전자에 손상과 중증도에 영향을 미치는 요인을 찾아 중증도 분류에 추가적으로 활용하고자 하였다. Collision Deformation Classification Code를 통해 차량 파손 정도를 확인하였으며 간편손상척도(Abbreviated Injury Scale, AIS)로 손상부위와 정도를, 손상중증도점수(Injury Severity Score, ISS)로 환자의 중증도를 확인하였다. 중증외상환자의 발생률은 5이상의 차량 파손 정도를 가진 대상자에서 Odds ratio가 7.381로 나타났으며 선형회귀분석을 통한 중증도 요인 분석에서도 차량 파손 정도의 ${\beta}$값이 0.453으로 나타났다. 따라서 5이상의 차량 파손 정도는 노인운전자에서 중증도 분류에 추가적으로 활용될 수 있는 기준으로 제안될 수 있다.

PURPOSES : The purpose of this study is to verify traffic accident injury severity factors for elderly drivers and the relative relationship of these factors. METHODS : To verify the complicated relationship among traffic accident injury severity factors, this study employed a structural equation model (SEM). To develop the SEM structure, only the severity of human injuries was considered; moreover, the observed variables were selected through confirmatory factor analysis (CFA). The number of fatalities, serious injuries, moderate injuries, and minor injuries were selected for observed variables of severity. For latent variables, the accident situation, environment, and vehicle and driver factors were respectively defined. Seven observed variables were selected among the latent variables. RESULTS : This study showed that the vehicle and driver factor was the most influential factor for accident severity among the latent factors. For the observed variable, the type of vehicle, type of accident, and status of day or night for each latent variable were the most relative observed variables for the accident severity factor. To verify the validity of the SEM, several model fitting methods, including ${\chi}^2/df$, GFI, AGFI, CFI, and others, were applied, and the model produced meaningful results. CONCLUSIONS : Based on an analysis of results of traffic accident injury severity for elderly drivers, the vehicle and driver factor was the most influential one for injury severity. Therefore, education tailored to elderly drivers is needed to improve driving behavior of elderly driver.

This study analyzed contributing factors affecting leg injury severity in pedestrian-vehicle crashes. A Binary Logistic Regression (BLR) method was used to identify the factors. Independent variables include characteristics for pedestrian, vehicle, road, and environmental conditions. The leg injury severity is classified into two classes, which are dependent variables in this study, such as 'severe' and 'minor' injuries. Pedestrian age, collision speed, and the height of vehicle were identified as significant factors for the leg injury. The probabilistic outcome of predicting leg injury severity can be effectively used in not only deriving pedestrian-related safety policies but also developing advanced vehicular technologies for pedestrian protection.

Purpose: No previous study has assessed elderly pedestrian traffic accidents based on a nationwide database. This study aimed to help primary physicians who examine patients in emergency departments to determine and make prompt and accurate treatment decisions. Methods: This study used data from the Emergency Department-based Injury Indepth Surveillance from 2013 to 2017, managed by the Korea Centers for Disease Control and Prevention. Pedestrians aged ${\geq}65years$ were included, and using multivariate logistic regression multiple factors were analyzed to determine their relationship with injury severity. Results: Of 227,695 subjects, 6,498 were included, of whom 2,065 (31.8%) were severely injured. There were more female than male patients in all severity groups. Most accidents occurred in the afternoon and on general roads. In the multivariate analysis, the odds ratio (OR) of injury severity for male pedestrians was 1.165 (95% confidence interval: 1.034-1.313, p=0.012). Older age of patients and the use of ambulances were associated with greater injury severity. The accident time affected the degree of injury severity; i.e., compared to dawn, injury severity increased in the morning (OR: 1.246, p=0.047) and decreased at night (OR: 0.678, p<0.001). A significant difference was noted in the correlation between the type of vehicle causing the accident and the accident severity; i.e., motorcycle accidents had lower severity than bicycle accidents (OR: 0.582, p=0.047). Conclusions: Injury severity was correlated with sex, age, transportation to the ED, TA onset time, and type of vehicle. The study results suggest that injury severity may be positively reflected in initial assessments and overall integrated treatments by physicians and in the related policies.

Purpose: This study examined the injury and rehabilitation of athletes with disabilities in racket sports projects (i.e., badminton, table tennis, and wheelchair tennis). In addition, the characteristics of each project and the differences among those projects are discussed. Methods: Business team athletes with disabilities in racket sport were enrolled as subjects (i.e., 19 badminton athletes, 19 table tennis athletes, and 19 wheelchair tennis athletes). The real conditions of the injury, injury severity, injury site, symptoms, and rehabilitation methods after injury were analyzed. Results: No significant differences were observed among the actual condition, injury severity, symptoms and the methods of rehabilitation on racket sport for athletes (i.e., badminton, table tennis, and wheelchair tennis athletes) with disability. The differences were focused mainly on the injury sites due to the characteristics of the different projects, and specific technical actions. Conclusion: This study examined the real condition of the injury, injury severity, injury site, symptoms and rehabilitation methods after the injury on the rackets (i.e., badminton, table tennis, and wheelchair tennis) athletes with disabilities. The data can be used to eliminate the incidence of injury and minimize the injury severity for racket athletes with disabilities. In addition, it can also be used for the disabled, who like racket projects, as the fundamental material to prevent injury and assist in recovery.

Purpose: The purpose of this study was to investigate factors influencing severity of occupational fall injury. Methods: A self-reported questionnaire was completed by 105 patients sustaining occupational fall injury between July 2010 and January 2013. The study instruments were developed by the National Traumatic Occupational Fatalities and National Electronic Injury Surveillance System. The questionnaire consisted of general characteristics of the subjects (30 items), workplace characteristics (12 items) and disaster characteristic (13 items). Results: Demographic factors, except age, did not affect the severity of injury. Injured patients aged 50-59 years tended to have more severe injuries than those aged 39 years. Type of transport vehicles, conditions, and the circumstances of the fall influenced injury severity. Patients transported by 119 ambulance suffered more severe fall injuries than those who were not. Electrical workers did not receive safety education wihin a year. Critical height in severe injuries was > 6 meters. Conclusion: Occupational fall injuries were influenced by patient age, types of transport vehicles, fall height, size of workplace, and safety education experience.

Purpose: Alcohol ingestion is a significant risk factor for injuries. However, the influence of high blood alcohol concentration about the severe traumatic injury is controversial. The aim of study was to analyze the injury severity, prognosis in severe traumatic patients according to alcohol ingestion. Methods: This study was performed retrospectively with severe traumatic patients (Injury Severity $Score{\geq}16$) who visited the emergency department at Pusan National University Hospital from January 2013 to December 2013. Results: In total 98 severe traumatic patients, blood alcohol concentration (BAC) positive group (BAC>30 mg/dl) is 42 (42.90%) patients and BAC negative group ($BAC{\leq}30mg/dl$) is 56 (57.10% )patients. Head and neck injury is significantly high in BAC positive group (35 patients, 83.3%) compared to BAC negative group (33 patients, 58.9%). Comparison of injury severity, outcome and mortality is not significantly different between two groups. Conclusion: In severe traumatic patients, head and neck injury occurred high in BAC positive group. Alcohol ingestion did not influence injury severity, outcome in severe traumatic patients. However, effort to decreasing injury related to alcohol ingestion and prospective multi-center study is needed.

Purpose: This study was conducted to test criterion-related validity of the Critical Patients' Severity Classification System (CPSCS) developed by the Hospital Nurses' Association by examining relationships with brain injury severity measured by Glasgow Coma Scale (GCS), recovery state measured by Glasgow Outcome Scale (GOS), and days of stay in ICU of brain injury patients. Methods: Prospective correlational research design was adopted by including 194 brain injury patients admitted to ICU of one university hospital. Results: The score of CPSCS appeared to significantly discriminate the severity of brain injury. Among nursing activities in CPSCS, Respiratory therapy, IV Infusion and Medication, Monitoring, Activities of Daily Living (ADL), Treatment and Procedure were significant to discriminate the severity of brain injury. Respiratory therapy, Vital Signs, and Monitoring appeared to significantly discriminate the recovery states of 1- and 3-months. Nursing activities significantly contributed to predict the days of ICU stay were Respiratory therapy, ADL, and Teaching and Emotional Support. Conclusion: CPSCS developed by the Hospital Nurses Association appeared to be valid to discriminate or predict brain injury severity, recovery states, and days of stay in ICU for brain injury patients.

Purpose: The arterial base deficit and the serum lactate level are widely recognized indicators of injury severity, adequacy of resuscitation and outcome. The purpose of this study is to evaluate the usefulness of the arterial base deficit as an injury-severity indicator in multiple-trauma patients with head injuries. Methods: Data were retrospectively collected from trauma patients over 18 years of age who had been admitted at the emergency center between October 2005 and July 2006. The patients were divided into head-injury and non-head-injury groups. These patients were then sub-divided into minor ($$ISS{\leq_-}15$$)-injury and major ($$ISS{\geq_-}16$$)-injury groups according to their injury severity scores (ISS). We analyzed the differences in the base deficits and the serum lactate levels between the major- and the minor-injury sub-groups in both the head-injury and the non-head-injury groups. Results: In the non-head-injury group, we found statistically significant differences in the arterial base deficit between the major-injury and the minor-injury sub-groups($-6.86{\pm}2.40mmol/L$ vs. $-1.37{\pm}0.73mmol/L$, p=0.010). In the head-injury group, no significant differences were noted between the two sub-groups($-2.50{\pm}1.28mmol/L$ vs. $-1.51{\pm}0.74mmol/L$, p=0.897). Moreover, the differences in arterial base deficit between the major-injury and the minor-injury sub-groups were not significant both for either single-head-trauma or multiple-head-trauma patients (p=0.643 vs. p=0.832). Conclusion: We conclude that neither the arterial base deficit nor the serum lactate level can be used to predict injury severity in multiple-trauma patients with head injuries.
