국가적 사회적 차원에서 국민의 안전과 보호에 대한 서비스의 인지가 사회 전반적으로 확산되어감에 따라 경상 환자, 상황이 급박한 중상환자까지 구급차 이용의 빈도수가 점차 증가하고 있다. 그러나, 구급차 이용의 빈도수가 증가함에 따라 이송 중 안전사고도 빈번해지고 있다. 이와 같은 원인은 신속하게 환자를 이송해야하는 구급차가 도로를 포함하여 구급차가 노출되는 환경에서 인식이 잘 되지 않을 뿐만 아니라, 이미 매우 높은 확률의 2차 사고에 노출 되어있다는 것이고, 이는 환자를 포함하여 구급대원에게도 생명이 담보된 위협적인 상황이라 할 수 있다. 특히 흐린 날이나 야간에 도로상의 구급차는 무방비 상태로 사고에 완전히 노출되어 있으므로 안전사고 대비를 위한 안전한 디자인의 연구 및 개발은 매우 시급하다고 할 수 있다. 또한, 구급차를 보다 원거리에서 인식이 되는 시인성이 높은 색상과 위급함을 직관적으로 인지할 수 있는 디자인 모티브를 추출하여 구급대원과 환자가 주변 환경으로부터 안전하게 보호 될 수 있으며, 현대감각에 맞는 연출로 구급차로서의 정체성을 살리고, 예민하고 불안한 환자의 심리상태를 고려하여 시각적으로 올 수 있는 위압감을 완화시킬 수 있어야 한다. 따라서, 본 연구에서는 기 연구된 선진 해외 사례를 분석하고, 국내 환경에 맞는 색상을 연구하여 이제까지 구급차에 대한 고착화 되어버린 색상에 대한 선입견을 버리고, 보다 안전한 색상 연구의 필요성을 파악하여 실제 한국형 구급차에 적용된, 현재 구급자동차 외관의 색상 및 패턴을 포함한 외관디자인이 나오게 된 과정에 대한 연구 결과이다.

Purpose: The severity classification in association with the time of visit to and the appropriateness of using a public ambulance for visiting the emergency department (ED) have not been thoroughly evaluated, and we aimed to evaluate these aspects. Methods: In this descriptive research, we retrospectively reviewed and analyzed the medical records of patients who visited the ED of the B General Hospital, Seoul from January to December 2019. Results: Of the 54,297 patients who were included in the analysis, 34,629 (63.8%) and 14,065 (25.9%) visited the ED directly and through public ambulances, respectively; 10,328 (73.4%) patients who used public ambulances were discharged home. In the daytime and nighttime, 24,891 (45.8%) and 29,406 (54.2%), respectively, visited the ED. The mean length of ED stay (LoS) of emergency and non-emergency patients was 326 and 159 minutes, respectively, and of patients classified as Korean Triage and Acuity Scale levels 1 and 2 was 427 and 430 minutes, respectively, which was longer than the total of 236 minutes. Conclusion: Patients who visited the ED using public ambulances constituted nearly 25% of all ED visits, and more than 70% of these patients were discharged home. Patients with high severity had a longer mean LoS, and daytime ED visits were characterized by higher numbers and severity of patients than nighttime ED visits.

This paper studies an emergency service vehicle location problem, where minimum reliability level pre-specified at each demand point is assured. Several models are suggested depending on the busy fraction, which is the time proportion of unavailability for the ambulances. In this paper a new model on computing the busy fraction is suggested, where it varies depending on the distance between the demand point and ambulances, hence it may respond the more realistic situation. The busy fraction for the ambulance location determined by the optimization model is computed by the simulation, and updated through the iterative procedure. It has been shown that the performances of the solutions obtained by the algorithm suggested for the instances appeared in the literature.

Purpose: We analyzed the characteristics and differences in patients' medical benefits and health insurance based on disease severity classification. Methods: We examined 29,139 patients who visited the emergency medical center of K Hospital from January 1,2016 to December 31, 2016. Survey items included the Korean Triage and Acuity Scale (KTAS) classification of emergency and non-emergency situations ratio and type of insurance. Results: According to KTAS classification, 76.2% of patients exhibited an emergency condition and 23.8% exhibited a non-emergency condition. Emergency patients exhibited more trauma than non-emergency patients. According to the type of insurance coverage, the duration of stay in the emergency room was longer for patients with medical care than for patients with health insurance. Additionally, 119 ambulances use was significantly higher among patients with medical care. Conclusion: Policy discussions should address alternative ways to replace the 119 ambulances used by patients in this study. Additionally, health care administrators should identify alternative care agencies as potential alternatives to emergency room visits.

Purpose: This study aimed to analyze the number of patients with and without medical history transported to the emergency department due to changes in daily temperature and season. Methods: Data on emergency activity sheet and daily weather were collected from March 2016 to February 2017 in the city of Gyeonggi-do. In total, 13,531 patients were transferred to the emergency department in 119 ambulance. Data were analyzed using the Statistical Package for the Social Sciences (version 21). Results: The daily average number of patients transferred was the highest in August and September, i.e., the summer season. The higher the daily highest and lowest temperatures, higher the daily average number of patients transferred. In contrast, patients with medical history of hypertension, diabetes, heart disease, cerebrovascular disease, and pulmonary disease had a higher incidence of transfers in the winter season and on days with lower temperature. Conclusion: The results indicate that as people become more active during the summer when temperatures are high, the chances of daily emergencies increases, whereas patients with medical history are more likely to experience emergencies when the temperatures were lower. Hence, 119 ambulances will have to be prepared in advance to deal with this trend.
