Purpose: Advanced airway maintenance improves the quality of cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients. In this study, we evaluate the factors associated with advanced airway management while performing CPR for out-of-hospital cardiac arrest patients by 119 emergency medical technicians (EMTs). Methods: The observational analysis method was used ro retrospectively collect data from 119 rescue run sheets. This study was conducted in a fire station in Seoul, Korea. The subjects of this study were defined as OHCA patients who received CPR from July 2016 to June 2018. We divided the subjects into two groups according to whether advanced airway maintenance was performed or not, and then compared and analyzed both groups. We performed logistic regression analyses for characteristics that differed significantly between groups. Results: Out of 188 OHCA patients, 146 (77.7%) had received advanced airway management. Statistically significant differences in the logistic analysis were found regarding the total number of EMT professionals (adjusted odds ration [aOR]: 1.955; 95% confidence interval [CI]: 1.227-3.115; p=0.005) and scene-time (aOR:1.119;95%CI:1.019-1.228;p=0.019). Conclusion: Advanced airway maintenance while performing CPR for OHCA patients by EMT associated primarily with ensuring an adequate numbers of EMT professionals and sufficient scene time.

Purpose: This study analyzed the information and accessibility of toxic substances provided to Internet websites. Methods: From August 1, 2020, to August 31, 2020, we analyzed eight internet websites regarding toxic pharmaceuticals, pesticides, and chemicals. The website-evaluation criteria were divided into five categories for information and five categories for website convenience. Results: All eight websites about toxic substances were hosted by reliable institutions or organizations and provided accurate information in terms of informational relevance. The website run by the Safety and Health Corporation scored the highest with 100points. Analysis of the websites' accessibility to non-members' revealed that six (75.0%) were accessible, but two (12.5%) provided only limited information. Access to information through mobile apps was only available in three of the eight cases (37.5%). Conclusion: This study can be used as a reference for Internet websites about toxic substances. Toxicological information that can be viewed only with membership and manager approval requires membership in advance of viewing. In addition, emergency medical personnel working at a site or hospital should be familiar with the characteristics of toxicity information retrieval.

Objective: The aim of this study was to identify the clinical characteristics and risk factors associated with the admission of patients in the emergency department (ED) within 30 days after discharge. Methods: A retrospective, observational study was conducted on adult patients presenting with abdominal pain to the ED of a single, urban, university hospital, between January 2014 and December 2015, who revisited the ED within 30 days after discharge. Data was collected on the emergency severity index level, time to contact doctors, physical examination, laboratory tests, use of computed tomography (CT), and patient disposition on revisitation. The primary outcome was hospital admission following an ED revisit in the 30-day period after the first visit. Results: During the study period, 19,480 patients visited the ED with the chief complaint of abdominal pain, and 13,577 were discharged. A total of 251 patients (1.29%) revisited the ED within 30 days, of which 89 were eligible for the study. The primary outcome was associated with not performing a CT scan on the initial visit and an increased C-reactive protein (CRP) value. Receiver operating characteristic curve analysis showed that a cut-off baseline CRP value of >0.35 mg/dL can predict the primary outcome with a sensitivity and specificity of 75% and 62.1%, respectively (area under the curve, 0.701; 95% confidence interval, 0.569-0.833; P=0.007). Conclusion: An increased CRP value and not performing abdominal CT were associated with a higher rate of admission following ED revisits of patients with abdominal pain. Future prospective studies on the role of abdominal CT imaging in patients presenting to the ED with abdominal pain will be needed.

Purpose: The purpose of this study was to provide basic data for improving the response capacity of 119 EMS systems by analyzing the effects of particulate matter on cardio-cerebrovascular and respiratory symptoms in the pre-hospital stage. Methods: We examined 46,389 patients who transferred to the hospital with complaints of cardiopulmonary arrest and cardio-cerebrovascular and respiratory symptoms by 119 ambulances in Incheon from 2016 to 2018. Results: The probability of 119 emergency dispatch for patients with cardiopulmonary arrest increased 2.8-4.0% from the day of symptom onset until two days before hospital presentation as particulate matter 10㎛ or less in diameter(PM₁₀) increased by 10㎍/㎥ (OR=1.028; 95% CI=1.014-1.041, p=0.000, lag 0), (OR=1.040; 95% CI=1.024-1.056, p=0.000, lag 1), (OR=1.032; 95% CI=1.016-1.049, p=0.000, lag 2). Meanwhile, emergency dispatch increased 3.6-6.1% for PM_2.5 in creased by 10㎍/㎥ (OR=1.046; 95% CI=1.024-1.068, p=0.000, lag 0), (OR=1.061; 95% CI=1.035-1.088, p=.000, lag 1), and (OR=1.036; 95% CI=1.010-1.063, p=0.006, lag 2). Conclusion: Emergency medical technicians (EMTs) who respond to 119 calls should rapidly and accurately evaluate patients and provide professional emergency care by identifying the characteristics of the vulnerable groups relative to particulate matter size. To prevent the occurrence and exacerbation of symptoms caused by particulate matter, EMTs should be prepared and equipped with a response system for high particulate matter in the EMS system.

The Emergency Department (ED) is an integral part of hospitals. Admissions from the ED account for a significant proportion for a hospital's activity. Ensuring a timely and efficient flow of patients through the ED is crucial for optimising patient care. In recent years, ED overcrowding and its impact on patient flow has become a major issue facing the health sector. Simulation is rapidly becoming a tool of choice when examining hospital systems due to its capacity to involve numerous factors and interactions that impact the system. An analytical simulation model is used to investigate potential impacts by changing the following aspects of ED (physical layouts; number of beds; number and rate of patient arrivals; acuity of illness or injury of patients; access to radiology and pathology services; hospital staffing arrangements; and access to inpatient beds). Results of a significant numerical investigation at a hospital are also presented.

Purpose: This dissertation is a descriptive research study analyzing the accuracy and reliability of the cardiopulmonary resuscitation (CPR) application developed in Korea. Methods: Two faculty members from the emergency medical services department and the emergency medicine department searched applications from July 1 to July 10, 2019 and selected a total of 13 applications. Twelve questions were assessed for information accuracy and three were assessed for reliability. In accordance with application types, the number and mean ± standard deviation were analyzed. The t-test was used to compare the accuracy of CPR information in accordance with information sources. Results: The results revealed the following errors: 7 cases (53.8%) identified the chest center lining from the nipple center-line as the chest pressure point; 5 cases (38.5%) did not provide information on the depth of 6 cm that should not be exceeded; and 4 cases (30.8%) did not provide advise to check respiration. When the CPR information sources were included, the information accuracy score was high; a significant difference was observed (p=.035). Conclusion: In the case of applications providing medical information regarding CPR, it is necessary to provide at least authoritarian, sources of information, and author transparency as well as continuous effort and attention.

Purpose: This study aimed to investigate the awareness and direction of paramedics work and image in hospitals. Methods: From April 16 to May 5, 2015, data were collected through structured questionnaires from 45 paramedics and 81 nurses working in emergency medical institutions. The data were analyzed using SPSS version 18.0. Results: The work of paramedics is evaluated to be highly worthy at the in-hospital level rather than at the injury first-aid treatment level. It appears that paramedics are often forced to do what their hospitals tell them to do concerning matters related to conflicts with them and nurses. Paramedics stated that they experienced greater mental stress than those engaging in other professions, a finding similar to those of other studies. There was no statistically significant difference in opinions between the two groups about a desirable direction for the development of first-aid services at hospitals. More than two thirds of the respondents said that paramedics should be given the right to enter acting check for patients. Conclusion: Paramedics work is shown to differ in the opinions of paramedics themselves and nurses. Paramedics need for reform is associated with expanding the work of the law.
