Objectives : The purpose of this study is to analyze the proportion of admission via the emergency room(the rest is ER) in an emergency medical center and to examine the factors related to admission. Methods : This study used 2005 National Health Insurance claims data for admitted patients of 112 hospitals having emergency medical centers in Korea. The study sample had 2,335,610 patients. The data was classified into emergency admission and non-emergency admission. To investigate the factors affecting the type of admission, the following were included as independent variables: type of health assurance_(national health insurance beneficiaries or medical aid beneficiaries), demographic characteristics_ (sex, age), cause of admission_ (disease or injury), whether an operation was performed or not, DRG severity level, the number of beds, and the location of the hospital. Data were analyzed using the Chi-square test for the differences in emergency admission rates for each variables, and multiple logistic regression analysis was used for identifying the factors affecting admission type. Results : The proportion of admission via the ER accounted for 40.6% of the total admission among hospitals having emergency medical centers. The risk of admission via ER was relatively high for patients who were male, the aged, the injured, the surgical patients, the patients having more severe symptoms, and the patients admitted the hospitals located in metropolitan areas, and the patients admitted the hospitals having 300-699 beds. Medical aid patients were more likely admitted through the emergency room than health insurance patients after other variables ware adjusted. Conclusions and Discussion : We analyzed the proportion of admission via the ER for the total admission rate of hospitals having an emergency medical center in Korea. And we explored the factors related to admission via the ER. This proportion may be used as an indicator of the adequacy of medical utilization or low accessibility to hospitals of patients with low socioeconomic status.

Objective: This study examined the predictive factors for prolonged length of stays of adult patients with acute appendicitis (AA) in an emergency department (ED). Methods: This was a retrospectively clinical study including patients in an ED. All patients were diagnosed from the clinical symptoms and a typical physical examination, and had undergone a computed tomography (CT) evaluation on the ED visiting date. All data were collected from the electrical medical records. The clinical parameters analyzed were the laboratory data, including the white blood cell count with differential values, C-reactive protein (CRP) level, initial vital signs, duration of admission, coexisting perforation of the appendix in the CT findings. The relationship between the clinical parameters and length of stay was assessed. Results: A total of 547 patients with AA were enrolled in this study. Among them, there were 270 male patients with a mean age of $40.7{\pm}15.8years$. The baseline characteristics, initial clinical features, laboratory, and imaging studies results of 129 patients in the prolonged length of stay (pLOS) group, and 418 patients of the non-pLOS group in AA were compared. Multivariable logistic regression analysis revealed the predictive factors related to pLOS in AA to be as follows: age 40 years or older, body temperature over $37.3^{\circ}C$, CRP level greater than 5.0 mg/dL, and evidence of perforation in CT findings (P<0.001). Conclusion: If we check age, fever, CRP level and find evidence of perforation, it might be helpful for predicting the increasing period of length of hospital stay for patients with AA in ED.

Purpose: There is ongoing demand to deliver better procedural training to medical students in the emergency department. Thus, we studied the efficacy of a cadaver-based training model for teaching simple suture techniques to medical students. Methods: We investigated ten fourth-year medical students, who were rounding and being trained in the Emergency Department of Chungnam National University Hospital. They were educated with slides about a simple suture technique for 30 minutes to evaluate the efficacy of the cadaver-based training model. We prospectively measured their skill by administering a test on the cadaver-based simple suture technique in 3cm sized linar wound separately to each of them. Results: A total of ten fourth-year medical students completed the investigation. The tension, the direction of suture, the degree of cleanness, the number of sutures, the adequacy of the cutting thread length, and the suturing time in the first attempt were compared with those in the second one. The second results were compared with those in the third one, and the third results were compared with those in the fourth one. All the results had statistical significance. Conclusion: These findings support the value of the cadaver-based simple suture technique training model as a medical student teaching model. The cadaver-based simple suture technique teaching model is a good way of teaching several medical skills to medical students.

Purpose: Non-benzodiazepine hypnotic drugs (including zolpidem) are associated with an increased risk of suicide and suicidal ideation. Considering the wide usage of zolpidem, this drug should be considered a possible etiology for stupor or coma in any patient exposed to this drug. However, there are no reports on zolpidem blood levels in emergency department patients in Korea. We therefore reviewed the analyzed data of a toxicology laboratory at one university affiliated hospital. Methods: The sex, age, chief symptoms, suspiciousness of poisoning, and presumption of poison were analyzed from January 2018 to June 2019. The detection frequency and level of zolpidem in the patient blood were compared to the mental changes presented, which is the main consequence of zolpidem. Results: A total of 229 toxicological analyses, requested to a toxicological laboratory at one university affiliated hospital, were reviewed. Among 229 patients, the mean age was 54.3±20.7 years old with 113 women and 116 men. 8.7% of patients have psychiatric illness and 39.7% were poisoned intentionally. The chief symptoms detected were: mental change 55.0%, gastrointestinal 14.4%, cardiovascular 10.5%, focal neurological 7.4%, respiratory 3.5%, none 8.7%, and unknown 0.4%. A request for detailed reports revealed that causative poisons were specified only in 20.1% cases. Zolpidem was detected in 22.3% cases (51/229), with median blood level 1.26 mg/L (interquartile 0.1, 5.06 mg/L) and urine 0.90 mg/L (interquartile 0.11, 5.6 mg/L). Furthermore, zolpidem was more frequently detected in toxicology analysis of patients where mental change was the primary symptom, as compared to other symptoms (32.5% vs. 9.7%, p<0.01). Conclusion: This study reported the blood level of zolpidem in suspected poisoning patients admitted to the emergency department.

Purpose: This study intended to improve quality of prehospital emergency care for trauma patients by figuring out its current situations and problems based on run-sheets and questionnaires of 119 emergency medical technicians (EMTs). Methods: This study conducted a research of 425 trauma patients transferred to the 3rd hospital in G-city by 119 ambulances from July 1, 2008 to June 30, 2009. We aslo utilized 114 copies with questionnaires of 119 EMTs working in J-province. The data were analyzed with SPSS 18.0. Results: There were 425 trauma patients including 272 men and 137 patients with traffic accident. When it comes to types of 119 EMTs who delivered cares to patients, there were 206 (48.5%) advanced EMTs, 101 (23.8%) basic EMTs, 50 (11.8%) nurses and 43 (10.2%) rescue education receivers. The most frequent measured vital sign was pulse rate (54.1%). Regarding assessment of systolic blood pressure, pulse rate and respiration rate, there were some significant differences in accordance with type of 119 EMTs. Among the 317 patients evaluated 'emergency' in field, 137 patients returned to their home. Prehospital emergency cares accounted for 861, around 2.0 treatments per a patient. In view of questionnaire, the 74.6% of 119 EMTs hoped supplement of man power for proper prehospital care to trauma patients. Conclusion: This study suggested that it is necessary to develop detailed guidelines for trauma patients so as to improve quality of trauma patient evaluation and prehospital care. Furthermore, improvement of emergency care systems will reduce mortality of trauma patients and lead to their good outcome.

현대 사회는 뜻밖의 사고와 위험 상황으로 불안정한 환경에 직면하고 있다. 예를 들어 분당 다리 붕괴사고와 이태원 압사사고 등이 그 예가 될 것이다. 이와 함께 급성심정지나 뇌졸중과 같은 중대한 응급상황이 발생하였을 때, 신속한 조치와 전문 의료 기관으로의 원활한 이송이 필요한 경우 또한 빈번하게 발생하고 있다. 이러한 위험 요소에 대응하기 위해 국가는 국민의 생명과 안전을 보호하기 위한 다양한 시스템을 구축하고 있는데, 119구급대는 응급 의료 시스템 중 핵심적인 역할을 수행한다. 중대한 외상 환자나 중증 질환 환자의 응급 상황에 즉각적으로 대응하여 손상을 최소화하고, 응급의료 기관으로 신속하게 이송하여 전문적인 치료를 제공함으로써 환자의 생명과 안전을 보호하는 것이 그 목표이다. 이와 관련된 핵심 활동이 구급활동인 것이다. 특히, 119구급시스템은 응급 환자의 병원 이송을 책임지는 핵심 기관이나, 구급대원들은 업무수행 중 구급활동 방해 사례에 여전히 직면하고 있다. 이러한 방해 사례는 경찰의 협조 노력에도 불구하고 줄어들지 않고 있고, 구급활동은 공무집행 방해죄와 유사한 특성을 지니며, 응급의료 시스템 내에서 근무하는 응급의료 종사자에 대한 폭행 및 장비 파손과 같은 사례와도 유사한 형태를 보인다. 따라서 119구급시스템을 포함한 응급 의료 활동을 수행하는 과정에서 발생하는 방해 문제에 대한 심층적인 이해와 개선 노력이 필요하다. 이러한 문제에 대한 해결책은 "소방기본법"과 "119구조·구급에 관한 법률"을 중심으로 구급활동 방해죄의 조건을 정립하고 개선하는 것이다.

Purpose: Prompt arrival of emergency vehicles at the scene is important. Therefore, special cases for emergency vehicles are being applied. However, there remain obstacles that obstruct the prompt arrival during dispatch. Methods: First, a literature review revealed five categories of problems with the emergency vehicle priority signal system. Then, the first Delphi survey was conducted to confirm the validity of the five categories. Further, a second Delphi survey was conducted to identify additional problems, and we used a 5-point Likert scale for a third Delphi survey. Results: A total of 92 items were extracted from preceding studies. The validity of the five categories was confirmed in the first Delphi survey. Then, 123 additional items were derived from the second Delphi survey, and the final 50 items were selected from 93 items obtained from the third Delphi survey. Conclusion: This study revealed problems and improvement measures for improving the operation of the emergency vehicle priority signal system that were not proposed in previous studies.

Purpose: The study aimed to analyze the occurrence and transfer status of emergency patients at Incheon International Airport in Korea. Methods: This study design included 810 patients for eight years, from July 1, 2014 to June 31, 2022. The collected data were analyzed with SPSS statistics version 25.0. Results: For the demographics, 531 (65.6%) were males, 151 (19.5%) were in the highest age group (in their 50s), and 289 (35.9%) were foreigners. The most common place of occurrence was in protected areas in the passenger terminal, with 341 (42.1%) of cases occurring here. The time of arrival at the site (z=-3.444, p=.001), stay duration at the site (z=-8.145, p=. 001), and transfer time (z=-3.623, p=.000) were all significantly longer. Conclusion: It is necessary to consider a rapid emergency transportation plan, such as developing a system that simplifies immigration procedures when emergency patients move from protected areas to general areas. Moreover, in order to quickly respond to foreign emergency patients, detailed characteristics will need to be identified. Lastly, considering the long transfer time, an instructing doctor should accompany an ambulance and actively perform advanced resuscitation.
