Purpose: This study validated the influential relations between the effects of emergency care quality, credibility of 119 emergency medical technicians (119 EMTs), and perceived usefulness and attitude of emergency care, focusing on the moderating effect of protectors' characteristics (education, experience, age, and recognition of patient severity). Methods: This study was based on elaboration likelihood and technology acceptance models. In total, 172 protectors with experience in utilizing prehospital service were surveyed from April 1 to July 31, 2011. Results: The results showed that the emergency care quality and the credibility of 119 EMTs were the main determinants of the perceived usefulness and attitude of emergency care, irrespective of the protector's characteristics (p <.001). In addition, the findings showed that the protector's intention of emergency care had a moderating role. The impact of the quality of emergency care on its perceived usefulness was greater for high-level protectors (p <.001). By contrast, the impact of the credibility of 119 EMTs on the perceived usefulness of emergency care was greater for low-level protectors (p <.001). Conclusion: The protectors' characteristics have different influences on the relations between the effects of emergency care quality, the 119 EMT credibility, and the perceived usefulness and attitude of emergency care.

Purpose : The purpose of this study is to provide the basic data to improve pre-hospital phase emergency care for acute myocardial infarction (AMI) patients by analyzing AMI patients' clinical characteristics and emergency care situations. Methods : Data were collected through medical records of 385 AMI patients including ambulance records of 107 AMI patients transferred to the emergency medical center for three and a half years. Results : Regarding emergency care for AMI patients in pre-hospital phase, 47% of the care revealed moderate level or higher, and appropriateness of pre-hospital phase emergency care for cardiopulmonary complaints practiced by paramedics showed statistically significant improvement in recent years (p<.001). The time from onset of symptom to ballooning intervention by 119 emergency services was shorter than that in other cases. However, emergency care by paramedic was mainly basic life support. Conclusion : Since prognosis of AMI shows vast differences depending on prompt detection and medical intervention, cooperation between pre-hospital and in-hospital phase is highly required. 119 paramedics should be trained focusing on the accurate assessment and emergency care, and medical direction should be activated. In addition, regulation on 12-lead EKG, cardiac enzyme analysis, use of analgesics and thrombolytic agents should be legally implemented.

Background: This study aimed to identify patterns of elderly patients who transferred from long-term care hospitals to emergency rooms and provide the evidence of emergency medical systems to prepare for a super-aged society. Methods: The data source was the National Emergency Department Information System database from January 2014 to December 2019 in Korea. We performed a cross-sectional study among elderly patients (≥65 years) who transferred from a long-term care hospital to an emergency room. Trend analysis was conducted by year. Results: We identified 225,765 elderly patients who were transferred from long-term care hospitals to emergency rooms between January 1, 2014 and December 31, 2019. The proportion of the study population and their mean age were recently increased (p<0.001, respectively). The proportion of elderly patients being re-transferred (p=0.049) and the patients re-transferred to long-term care hospitals is significantly increased (p=0.005). Conclusion: The establishment of efficient emergency medical services for an aging society is important. It is necessary to develop a healthcare network with the government, long-term care hospitals, and medical institutions in the community suitable for preventing disease deterioration.

The purpose of this study was to provide the basic data for improvement of Emergency Medical Service System in Kwangju. The EMSS can be defined as the complete chain of human and physical resources that provides patient care in cases of sudden illness and injury. To provide effective emergency care through the EMSS in a region, the issue of training especially as it relates to EMT in EMSS delivery is more important than emergency medical equipment and facilities for pre-hospital emergency care. The transport of emergency medical patients carried out almost by 119 Emergency Medical Services. But out of all the employees at 119 EMS only 19.0% have graduated with a major in Emergency Medical Technology. It would seem prudent then that the graduates of EMT programs should gradually replace employees working at 119 EMS that do not have an EMT degree to ensure the best possible pre-hospital care for emergency medical patients. Therefore it can be expected that in the future there should an enormous demand for qualified EMT professionals to meet the growing needs for a superior level of emergency medical care for civilian.

Purpose : The purpose of this study was to analyze the prehospital care report prepared by EMS squads of 119 center in Gyeonggi area and to identify the status of prehospital care activities, problems and improvement possibilities of the emergency care. Method : Five hundred copies of prehospital care report prepared by EMS squads in thirty-eight 119 centers under 18 fire stations in Gyeonggi area from March to April in 2008 were randomly chosen for the analysis. Data abstracted according to the purpose of the study were input and the analysis of prehospital care activities were performed using SPSS-WIN(ver. 16) statistics package. Results : 1. Total 500 cases of prehospital emergency care activities were reviewed. By sex, females were 219 (43.8%) and males were 281 (56.2%). The places of reporting were home (57.8%). According to the type of emergency, 281 cases (56.2%) were caused by disease and 291 (43.8%) were from other causes such as traffic accidents or incidental injuries. 2 The average time needed for the 119 EMS squad to arrive at the scene after being reported was 7.29 minutes. The time used at the scene for the emergency care was 7.3 minutes in average and the time to arrive at the hospital was 25.4 minutes in average. 3. In patient evaluation, in 68% of the cases more than two vital signs were measured at one time and emergency patients were 31%, and non-emergency patients were 69%. 4. In one EMS activity, average 2.15 cases of emergency care were provided to a patient. The cases where two kinds of emergency care were given were 14.4%, which is the most frequent cases. When reviewing the details of the emergency cares given to the patient including multiple cares, trivial cards (taking it easy and giving comfort) were the most frequent one as 40.6% and the medical direction of the doctor was given in only one case out of 500 cases. 5. In patient evaluation and emergency care, vital signs were provided to emergency patients at significantly higher rate comparing to the non-emergency patients. The number of emergency care performance was significantly higher in emergency cases. In emergency dispatch, the cases that EMT (1st class) was on board was 86.2%. When comparing the cases when the 1st class EMT was on board and otherwise, the cases with the presence of 1st class EMT showed more vital signs were detected but there was no significant difference in the number of emergency cares provided. Conclusion : It seemed that the on-scene emergency care did not satisfy the expectations. So it is necessary to enforce the cooperation between the elements, the qualifications of the 119 EMS squads and to improve the prehospital working environment in order to provide the better medical service at any time.

Purpose: This study aims to analyze the current state of emergency care for patients with anaphylaxis and to identify problems and areas for improvement in prehospital care. Methods: This study was conducted using 119 emergency running sheets and medical records of 109 patients diagnosed with anaphylaxis. Questionnaires were also given to emergency medical technicians (EMTs) and emergency physicians. The data were analyzed using SPSS 21.0. Results: Prehospital emergency care included oxygen administration in 64.2%, an intravenous line in 15.6%, and medication injection in 11.0%. The most commonly administered medications were antihistamines in 66.7% and epinephrine in 8.3%. Of EMTs surveyed, 47.0% suggested an epinephrine injection and using direct medical control, while 53.8% of the emergency physicians suggested an epinephrine injection and using indirect medical control. Most emergency physicians 88.8% responded that epinephrine could be administered by EMTs. Conclusion: The data support epinephrine injection of patients with anaphylaxis by EMTs, but a larger sample size of EMTs is required. Education about the treatment of anaphylaxis should be improved for EMTs. The scope of paramedic responsibilities should also be redefined.
