ABSTRACT
This study aimed to investigate the prevalence of carbon monoxide (CO) poisoning and the provision of hyperbaric oxygen therapy (HBOT) in South Korea. We used data from the Korea Health Insurance Review and Assessment service. In total, 44,361 patients with CO poisoning were identified across 10 years (2010–2019). The prevalence of CO poisoning was found to be 8.64/10,000 people, with a gradual annual increment. The highest prevalence was 11.01/10,000 individuals, among those aged 30–39 years. In 2010, HBOT was claimed from 15 hospitals, and increased to 30 hospitals in 2019. A total of 4,473 patients received HBOT in 10 years and 2,684 (60%) were treated for more than 2 hours. This study suggested that the prevalence of both CO poisoning and HBOT in Korea gradually increased over the past 10 years, and disparities in prevalence were observed by region.
ABSTRACT
Purpose@#A pilot project using epinephrine at the scene under medical control is currently underway in Korea. This study aimed to determine whether prehospital epinephrine administration is associated with improved survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients who received epinephrine during cardiopulmonary resuscitation (CPR) in the emergency department. @*Materials and Methods@#This retrospective observational study used a nationwide multicenter OHCA registry. Patients were classified into two groups according to whether they received epinephrine at the scene or not. The associations between prehospital epinephrine use and outcomes were assessed using propensity score (PS)-matched analysis. Multivariable logistic regression analysis was performed using PS matching. The same analysis was repeated for the subgroup of patients with non-shockable rhythm. @*Results@#PS matching was performed for 1084 patients in each group. Survival to discharge was significantly decreased in the patients who received prehospital epinephrine [odds ratio (OR) 0.415, 95% confidence interval (CI) 0.250–0.670, p<0.001]. However, no statistical significance was observed for good neurological outcome (OR 0.548, 95% CI 0.258–1.123, p=0.105). For the patient subgroup with non-shockable rhythm, prehospital epinephrine was also associated with lower survival to discharge (OR 0.514, 95% CI 0.306–0.844, p=0.010), but not with neurological outcome (OR 0.709, 95% CI 0.323–1.529, p=0.382). @*Conclusion@#Prehospital epinephrine administration was associated with decreased survival rates in OHCA patients but not statistically associated with neurological outcome in this PS-matched analysis. Further research is required to investigate the reason for the detrimental effect of epinephrine administered at the scene.
ABSTRACT
Objective@#The number of elderly people visiting emergency rooms is rapidly increasing. Fever is one of the common complaints of patients who come to the emergency room, and it is often difficult to determine its cause in elderly patients only through basic examinations and tests. This study sought to verify the relationship between computed tomography and emergency department revisits of febrile elderly patients. Methods: This study is a retrospective medical record analysis study. Patients who came to our emergency room between September 2016 and September 2019, aged 65 years or more, and with body temperature higher than 37.8°C at the time of presentation or during their stay in the emergency room were enrolled. Patient age, sex, vital signs at triage, laboratory tests, whether computed tomography (CT) was conducted or not were analyzed. The primary outcome was set as revisits to the emergency department within 72 hours after discharge, due to any reason. @*Results@#Three thousand two hundred and forty patients were enrolled and of these 289 patients revisited the emergency department (ED). In the revisit (-) group, CT was performed on 44.09% of patients and 54.67% of patients in the revisit (+) group thus showing a statically significant difference. @*Conclusion@#This study showed that in elderly patients with fever presenting to the ED, patients who underwent a CT had 1.558 higher odds of revisit to the ED compared to patients who did not undergo a CT. From this result, it should be considered that the decision to discharge the febrile elderly patients based on the results of CT examination may not be appropriate.

ABSTRACT
Purpose@#The purpose of this study was to conduct a systematic review to investigate the socio-economic benefits of the poison control center (PCC) and to assess whether telephone counseling at the poison control center affects the frequency of emergency room visits, hospitalization, and length of stay of patients with acute poisoning. @*Methods@#The authors conducted a medical literature search of the PubMed, EMBASE, and Cochrane Library databases. Two reviewers evaluated the abstracts for eligibility, extracted the data, and assessed the study quality using a standardized tool. Key results such as the cost-benefit ratio, hospital stay days, unnecessary emergency room visits or hospitalizations, and reduced hospital charges were extracted from the studies. When meta-analysis was possible, it was performed using RevMan software (RevMan version 5.4). @*Results@#Among 299 non-duplicated studies, 19 were relevant to the study questions. The cost-benefit ratios of PCC showed a wide range from 0.76 to 36 (average 6.8) according to the level of the medical expense of each country and whether the study included intentional poisoning. PCC reduced unnecessary visits to healthcare facilities. PCC consultation shortened the length of hospital stay by 1.82 (95% CI, 1.07-2.57) days. @*Conclusion@#The systematic review and meta-analysis support the hypothesis that the PCC operation is cost-beneficial. However, when implementing the PCC concept in Korea in the future, it is necessary to prepare an institutional framework to ensure a costeffective model.
ABSTRACT
Purpose@#The purpose of this study was to investigate the cause of acute fatal poisoning and the time of death by analyzing the National Emergency Department Information System (NEDIS) of South Korea. @*Methods@#The NEDIS data from 2014 to 2018 excluding non-medical visits were used for this study. The patients with acute poisoning were extracted using diagnostic codes. The toxic substances were classified into pharmaceuticals, pesticides, gases, artificial poisonous substances, and natural toxic substances. Patients were classified according to the time of death, place of death, and region. In each case, the most causative substances of poisoning were identified. @*Results@#There were 380,531 patients including poisoning-related diagnoses, of which 4,148 (1.1%) died, and the WHO age-standardized mortality rate was 4.8 per 100,000. Analysis of 2,702 death patients whose primary diagnosis was acute poisoning, the most common cause of poisoning death was pesticides (62%), followed by therapeutic drugs, gas, and artificial toxic substances. Herbicides were the most common pesticides at 64.5%. The proportion of mortality by time, hyperacute (7 d) were 9.8%. @*Conclusion@#This study suggests that the most common cause of poisoning death was pesticides, and 60% of deaths occurred within 24 hours. The 71% of mortality from pesticides occurred within 6-24 hours, but mortality from gas was mostly within 6 hours. According to the geographic region, the primary cause of poisoning death was varied to pesticides or pharmaceuticals.
ABSTRACT
Background@#It is important to communicate accurately in the emergency department. Due to COVID-19 pandemic, a mask is mandatory to protect medical staffs and patients from infectious diseases, and the mask is known to disturb speech intelligibility. The objective of this study is to find out if a transparent mask can affect communication. @*Methods@#: We conducted a randomized pre- and post-test trial with 40 participants in a real emergency room environment. The reader puts on a mask and read aloud sentences which are frequently used between medical staffs and patients or among medical staffs. The type of mask was randomly assigned to the reader which was transparent or non-transparent. Frequently used 5 sentences between medical staffs and patients and 5 sentences among medical staffs from prepared 100 sentences were randomly selected and recited. Participants were told to write down the sentences they heard. Each sentence written down was graded 0 or 1. After writing down 10 sentences, reader puts on another type of mask and the same experiment was done. The order of transparenton-transparent mask was randomly allocated to each participant. @*Results@#: In frequently used sentences between medical staffs and patient, average score with a transparent mask was 4.88, and with a non-transparent mask was 4.50(p=0.001). In frequently used sentences among medical staffs, average score with a transparent was 4.77, and with a non-transparent mask was 4.05(p<0.001). @*Conclusions@#This study showed the transparent mask improves speech intelligibility when communicating in an emergency room.
