ABSTRACT
Purpose@#Most bee sting injuries are benign, although sometimes they can result in life threatening outcomes, such as anaphylaxis and death. The purpose of this study was to investigate the epidemiologic status of bee sting injuries in Korea and to identify risk factors associated with severe systemic reactions (SSRs). @*Materials and Methods@#Cases were extracted from a multicenter retrospective registry for patients who had visited emergency departments (EDs) for bee sting injuries. SSRs were defined as hypotension or altered mental status upon ED arrival, hospitalization, or death. Patient demographics and injury characteristics were compared between SSR and non-SSR groups. Logistic regression was performed to identify risk factors for bee sting-associated SSRs, and the characteristics of fatality cases were summarized. @*Results@#Among the 9673 patients with bee sting injuries, 537 had an SSR and 38 died. The most frequent injury sites included the hands and head/face. Logistic regression analysis revealed that the occurrence of SSRs was associated with male sex [odds ratio (95% confidence interval); 1.634 (1.133–2.357)] and age [1.030 (1.020–1.041)]. Additionally, the risk of SSRs from trunk and head/ face stings was high [2.858 (1.405–5.815) and 2.123 (1.333–3.382), respectively]. Bee venom acupuncture [3.685 (1.408–9.641)] and stings in the winter [4.573 (1.420–14.723)] were factors that increased the risk of SSRs. @*Conclusion@#Our findings emphasize the need for implementing safety policies and education on bee sting-related incidents to protect high-risk groups.
ABSTRACT
Purpose@#This study investigated the association of the index method, defined as the method used in the first suicide attempt (SA), with the outcome of SAs among adolescents. @*Methods@#The study analyzed medical records of 227 adolescents aged 10-18 years with clear SAs who visited the emergency department of Severance Hospital in Seoul, Korea from January 2007 through February 2021, focusing on the index methods and meaningful SAs defined as hospitalization, death or transfer to another hospital for psychiatric hospitalization. The association of the index method with the meaningful SAs was quantified using logistic regression. @*Results@#Among the 227 adolescents, 80 underwent the meaningful SAs (35.2%). The adolescents with the meaningful SA chose drug intoxication, fall, and hanging as the index methods more frequently than those without the outcome, whereas they showed a reverse pattern in cutting (P < 0.001). The association of fall or cutting with the meaningful SAs remained significant after adjustment (fall: adjusted odds ratio, 6.93 [95% confidence interval, 1.70-28.26]; cutting: 0.39 [0.17-0.91]; compared with those undergoing drug intoxication). Multiple SAs were also associated with the meaningful SA (1.76 [1.04-3.13]). @*Conclusion@#This study identifies the index method and multiple SAs as factors associated with the meaningful SA among adolescents in the emergency department. This finding may be helpful in interviewing adolescents with SAs.
ABSTRACT
Purpose@#Given the morphological characteristics of schistocytes, thrombotic microangiopathy (TMA) score can be beneficial as it can be automatically and accurately measured. This study aimed to investigate whether serial TMA scores until 48 h post admission are associated with clinical outcomes in patients undergoing targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA). @*Materials and Methods@#We retrospectively evaluated a cohort of 185 patients using a prospective registry. We analyzed TMA scores at admission and after 12, 24, and 48 hours. The primary outcome measures were poor neurological outcome at discharge and 30-day mortality. @*Results@#Increased TMA scores at all measured time points were independent predictors of poor neurological outcomes and 30-day mortality, with TMA score at time-12 showing the strongest correlation [odds ratio (OR), 3.008; 95% confidence interval (CI), 1.707–5.300; p<0.001 and hazard ratio (HR), 1.517; 95% CI, 1.196–1.925; p<0.001]. Specifically, a TMA score ≥2 at time-12 was closely associated with an increased predictability of poor neurological outcomes (OR, 6.302; 95% CI, 2.841–13.976; p<0.001) and 30-day mortality (HR, 2.656; 95% CI, 1.675–4.211; p<0.001). @*Conclusion@#Increased TMA scores predicted neurological outcomes and 30-day mortality in patients undergoing TTM after OHCA. In addition to the benefit of being serially measured using an automated hematology analyzer, TMA score may be a helpful tool for rapid risk stratification and identification of the need for intensive care in patients with return of spontaneous circulation after OHCA.
ABSTRACT
Objective@#Aneurysmal subarachnoid hemorrhage (SAH) is a common emergency condition, resulting in high morbidity and mortality. The delta neutrophil index (DNI), which reflects the fraction of circulating immature granulocytes, is significantly associated with systemic inflammation after infection or sterile injury. Aneurysmal SAH also leads to systemic inflammation after a brain injury. This study aimed to evaluate the relationship between the DNI and poor neurologic outcomes in patients with aneurysmal SAH. @*Methods@#We retrospectively identified patients (>18 years old) with aneurysmal SAH consecutively admitted to the emergency department (ED) between January 1, 2011, and November 30, 2018. The diagnosis of aneurysmal SAH was confirmed using clinical and radiological findings. DNI was determined at 0, 24, 48, and 72 hours after ED admission. The primary result was a poor neurologic outcome using the modified Rankin scale. @*Results@#A total of 352 patients with aneurysmal SAH were included in this study. A multivariable logistic regression model revealed that a high value of DNI at 24 hours after ED admission was a strong independent predictor of poor neurologic outcome upon discharge (odds ratio [OR], 1.471; 95% confidence interval [CI], 1.081-2.001; P=0.014). Among patients with aneurysmal SAH, DNI >1.0% at 24 hours was significantly associated with poor neurologic outcomes upon discharge (OR, 5.037; 95% CI, 3.153-8.044; P<0.001). @*Conclusion@#DNI can be determined easily and rapidly after ED admission without any additional cost or time burden. A high DNI value at 24 hours after ED admission is significantly associated with a poor neurologic outcome upon discharge among patients with aneurysmal SAH.
ABSTRACT
Objective@#This study aimed to investigate the risk factors of post-contrast acute kidney injury (PAKI) and the usefulness of the Mehran score for predicting PAKI in patients who underwent contrast-enhanced abdominopelvic computed tomography (CE-APCT) in the emergency department (ED). @*Methods@#This was a retrospective observational study. Patients who underwent CE-APCT and had a follow-up creatinine test within 72 hours in the period January to June, 2017, were enrolled for the study. PAKI is defined as a 25% or higher increase in the level of serum creatinine (sCr) within 72 hours after receiving contrast, or an increase in the level of sCr by 0.5 mg/dL. The odds ratio (OR) of risk factors and incidence of PAKI after CE-APCT were analyzed according to the Mehran risk group, and compared to expected incidence. Univariate and multivariate logistic regression analyses were performed for each risk factor. @*Results@#A total of 1,718 patients were enrolled in the study. Of these, 203 patients (11.8%) developed PAKI, and 2 patients (0.1%) required dialysis. Hypotension (systolic blood pressure <80 mmHg) was determined to be statistically significant (P=0.029; OR, 3.181) among the considered risk factors of PAKI. In the group having abnormal estimatedglomerular filtration rate (<90 mL/min/1.73 m2), the age and rate of the underlying disease (congestive heart failure, hypertension) was found to be higher in the PAKI group. The receiver operating curve of Mehran score (area under the curve: 0.521 in model A, 0.520 in model B) was statistically not significant in the univariate analysis. A higher Mehran score was associated with a higher proportion of patients who underwent prophylactic treatment. @*Conclusion@#There are no definite useful risk factors, including the Mehran score, for predicting PAKI in patients who underwent contrast-enhanced computed tomography in the ED.

ABSTRACT
Objective@#Within the last 2 years, coronavirus disease 2019 has spread rapidly across several continents, with 100 million confirmed infected patients. Physical barrier enclosure, also called “aerosol-box,” is a solution for the shortage of protective devices and spaces. In this study, we examined the safety of the novel barrier enclosure. @*Methods@#We simulated droplets by nebulizing 1% glycerol+99% ethanol solution. Two experienced physicians performed intubation under two conditions, such as the isolator condition (applying isolator without negative condition) and the negative pressure condition (applying isolator with the negative condition). We compared two conditions with two control groups, including negative control (room air) and positive control (synthetizing droplet air). During the procedure, particles were counted for 30 seconds, and this was repeated 10 times. At each condition, depending on the result of the normality test (Shapiro-Wilk test), an independent t-test was used when normality was satisfied, and a Mann-Whitney U-test was used when normality was not satisfied. @*Results@#The total number of particles in the positive control was 308,788 (175,936-461,124). The total number of particles for both conditions was significantly less than the positive control. Total number of particles in the isolator condition was 30,952 (27,592-33,244, P=0.001) and that in the negative pressure condition was 27,890 (27,165-29,786, P=0.001). @*Conclusion@#The novel barrier significantly reduces synthetizing droplets exposure during intubation. Application of negative pressure through the isolator results in an additional decrease in particle exposure. Studies involving a larger population of operators and prolonged procedures are required.
ABSTRACT
Objective@#It is important to identify high-risk elderly patients in the emergency department (ED), and various screening tools should be used. This study aimed to find the most appropriate tool by comparing frailty screening tools used in the ED. @*Methods@#The authors searched PubMed, EMBASE, Cochrane library, and KoreaMed databases for medical literature. Two or more frailty screening tools were studied. Sensitivities and values of the area under the receiver operating characteristic curve of each tool used in individual studies were compared. @*Results@#After the screening process, six studies using 12 tools were selected. Most of the tools had low sensitivities. The sensitivities were 90% or more in case of the Clinical Frailty Scale (CFS) and Program of Research to Integrate Services for the Maintenance of Autonomy (PRISMA-7). Seniors at Risk (ISAR) tools for frailty screening, Vulnerable Elders Survey (VES-13) and Geriatric (G8) tools were identified for predicting postoperative mortality, and CFS, Fried and Stable, Unstable, Help to walk, Bedbound (SUHB) tools were used for determining bad composite outcomes. The areas under the curve values predicting outcome were as follows: 0.63-0.67 for death, 0.52-0.64 for postoperative death, 0.52-0.68 for postoperative adverse outcome, 0.55-0.64 for poor prognosis, 0.65-0.69 for activity daily living disability, 0.66-0.78 for functional decline, 0.58-0.61 for hospitalization, 0.57-0.59 for fall, and 0.77-0.91 for frailty screening. @*Conclusion@#It was difficult to select the most appropriate tool among the 12 frailty tools included in this review. However, Fatigue, Resistance, Ambulation, Illnesses, Loss of weight (FRAIL), Study of Osteoporotic Fracture (SOF), CFS, VES-13, and PRISMA-7 were relatively useful in the ED.
ABSTRACT
Purpose@#Acute nicotine poisoning by liquid nicotine in electronic cigarettes is becoming an increasing problem worldwide. The current systematic review aimed to determine the harm of acute nicotine poisoning by reviewing published case reports. @*Methods@#An online literature search with PubMed, Embase, Cochrane Library, and KoreaMed database was performed to identify relevant studies addressing acute nicotine poisoning with electronic cigarettes. Two investigators searched the case reports written in English or Korean. @*Results@#Twenty-six cases were included in this study. The routes of intoxication included ingestion in 18 cases, intravenous injection in three cases, subcutaneous injection in two cases, and ocular exposure in two cases. Ten cases had a cardiac arrest, and seven of them died. Seven out of 12 cases with intentional poisoning had a cardiac arrest. Nine children under 18 years were reported, and three of them had a cardiac arrest. Sixteen cases without a cardiac arrest recovered well, except for one case with sudden sensorineural hearing loss. @*Conclusion@#The authors reviewed the risks of electronic cigarette liquid in terms of acute poisoning through a systematic review.The nicotine solution of an e-cigarette can be life-threatening in cases of acute poisoning. Therefore, active emergency treatment with early recognition is necessary. In addition, various management methods and regulations for preventing acute nicotine poisoning, such as restriction of distribution and nicotine concentration, should be considered.

ABSTRACT
Background@#: Since primary emergency treatment should be performed appropriately and promptly, efficient and accurate communication between paramedics and medical staff is paramount to a successful primary emergency treatment and patient handover. The problem of the training program in Korea is that it concentrates more on in-class lectures, often delivered by non-medical specialists, who may lack in practical experience and without proper communication training. To solve this problem, we have devised a simulation based training that focuses on event debriefings and two-way communication. @*Methods@#: 62 paramedics from 3 stations enrolled in the study. 4 different courses with different emergency situations were created and each course was taken twice resulting in a total of 8 classes. All courses were based on actual cases. The curriculum consisted of subject lectures with guidelines, skill practice courses, and simulation courses based on hands-on method. In simulation courses, paramedics use standardized check list to communicate with medical specialists. All curriculums except subject lectures include debriefing, which allows free talking with educators comprised of medical specialists. In order to measure the educational impact, all students performed self-assessment through a structured questionnaire before and after the training. @*Results@#: Regardless different situations and paramedics’ education level, their performance and communication skills have improved after simulation training course. Paramedics mentioned learning skills in simulation course through communication with medical staffs as the biggest advantage. @*Conclusion@#: Receiving the simulation training with standardized communication tools is effective at enhancing the communication between the paramedics and medical staff.
ABSTRACT
Background@#: Effective communication between doctors and patients is very important not only for diagnosis and treatment but also for building trust. Although teaching communication skills is very important in medical schools, there are limitations such as the number of students and the uncertainty of the patient population. Therefore, this study evaluates the effect of Fishbowl method to teach communication skills to medical students, which involves the medical students communicating with standardized patients in front of a large classroom and being observed by rest of the students. @*Methods@#: This study involves 10 weeks of educating 126 fourth grade medical students and graduates. During this period, total 8 classes were taken by subjects, where each class lasts 2 hours and is conducted by observing treatments of the standardized patients on 14 clinical topics by randomly selected medical students and giving feedback on the communication skills of the selected medical students. The educational effect was evaluated based on the scores of the clinical performance examination before and after the classes. @*Results@#: The scores assessed for medical history taking before and after the training are increased by 2.45 (p<0.001) and the scores for patient-doctor relationship is increased by 7.56 (p<0.001). @*Conclusions@#: It is expected to improve the communication skills of medical students by large scale lectures with standardized patients.
ABSTRACT
Background/Aims@#Patients treated with endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) are at risk of developing metachronous gastric cancer (MGC).The aim of this study was to evaluate the clinical outcomes of MGC after ESD for EGC between the re-ESD and surgery groups. @*Methods@#In total, data from 1,510 patients who underwent ESD for EGC from January 2005 to May 2014were retrospectively reviewed, and data from 112 patients with MGC were analyzed according to the type of treatment, namely, re-ESD and surgery. The clinicopathological factors affecting the subsequent treatment and outcomes of MGC were evaluated. @*Results@#The median duration to the development of MGC was 47 months. In multivariate analysis, lower body mass index (BMI) (p=0.037) and multiplicity (p=0.014) of index cases were significantly associated with subsequent surgery for MGC. In cases of MGC, a diffuse or mixed-type Lauren classification (p=0.009), the depth of tumor mucosal invasion (p=0.001), and an upper stomach location (p=0.049) were associated with surgery. Overall survival was significantly shorter in the surgery group than in the re-ESD group after treatment for MGC (log-rank test, p=0.01). @*Conclusions@#Lower BMI and multiplicity of index cancers were significantly associated with the surgical resection of MGC. Close follow-up is needed to minimize additional treatment for cases at high risk of advanced MGC after ESD for EGC.
ABSTRACT
Disasters have frequently been a problem in Korea. Many initiatives have been carried out to mitigate this problem and to respond to disasters properly. The National Medical Emergency Center organized the Disaster Medical Response Center, which operates 24 hours a day. Regional emergency medical centers were designated as hospitals that receive disaster victims. Along with the designated disaster hospitals, the Ministry of Health and Welfare, city and district governments, and community health centers were all assigned standard roles to carry out in case of disasters. Disaster medical assistance teams were developed to respond to disaster events in their regions. This system has enabled a more rapid and systematic response to disaster events, and has standardized disaster-related medical equipment and vehicles to ensure the proper treatment of disaster victims. Although many valuable systems have been developed to respond to disasters, practical training within each institution and community-wide team training are still lacking; therefore, the government needs to further develop and support such programs.

PURPOSE: Gastric cancer is the third-leading cause of cancer-related death in Korea. As the Korean population is ageing, the number of extremely old patients with this disease is increasing. This study examined the clinicopathological characteristics of gastric cancer in extremely old (over 85 years) patients who received treatment or conservative observations and compared the treatment outcomes according to the treatment modality. MATERIALS AND METHODS: A total of 170 patients over 85 years of age were diagnosed with gastric cancer. Of these, 81 underwent treatment for gastric cancer and 89 received conservative observations. The clinicopathological characteristics of the treatment and conservative groupswere compared. RESULTS: The mean age of the patients was 86.5 years. The conservative group included significantly more patients with older ages, macroscopically advanced cancer and upper-middle located cancer. The overall survival rate of the treatment group was significantly higher than that of the conservative group. The disease-specific mortality rate was significantly lower in the treatment group than in the conservative group. Multivariate analysis revealed the clinical course, alarm sign, and macroscopic classification to be independent prognosis factors. CONCLUSION: By itself, the chronological age should not be used as a strategy to determine whether treatmentwill be administered for gastric cancer. Patients who have early gastric cancer or lower-risk preexisting comorbidities should not be discouraged from treatment, even if they are older than 85 years.

Through the Declaration of Montevideo in 2011, the World Medical Association suggested that doctors worldwide should be trained in basic disaster response regardless of their specialty. The Haiti earthquake in 2010, which had the highest number of foreign medical team dispatched from all over the world, proved that untrained and disorganized team only brought confusion. This event led the World Health Organization to develop the ‘Classification and Minimum Standards for Foreign Medical Teams in Sudden Onset Disasters ’ in 2013. This guideline will become the standard for organizing an international emergency medical team. We should be able to provide high standard of care through field hospital set up and continuous training of disaster medicine specialists.

PURPOSE: Despite the clinical and socio-economic impact of acute poisoned patients, many of the treatments are not standardized in Korea. Moreover, no formal training that is specifically focused on clinical toxicology exists. Rather, training and education are conducted case by case in various institutions. This study was conducted to develop a standardized simulation-based clinical toxicology training curriculum for healthcare providers. This program will focus on specific assessment and treatment of critical toxicology patients, specifically those who have been poisoned with organophosphate. METHODS: The study was performed using a pre- and post-design to determine the effects of implementation of this program. The study was conducted at eight different urban teaching hospitals in a simulated room in the clinical area. The study was targeted to 19 groups composed of emergency residents and nurses. Simulation-based learning was conducted for each group. RESULTS: All 19 groups achieved the minimum passing score of 75%. Implementation of the program led to improved performance rates for overall management and cooperative moods competency (p<0.01). Inter-rater agreement between the two evaluators was excellent. In general, the participants thought the program was realistic and were able to recognize and improve the competencies needed to care for organophosphate poisoned patients. CONCLUSION: Simulation-based learning is an effective educational strategy that can be applied to improving and understanding proper care for rare but critical patients. This program was effective at improving team performance and cooperative moods when managing an organophosphate poisoned patient in the Emergency Department.

OBJECTIVE: Tube thoracostomy (TT) is a commonly performed intensive care procedure. Simulator training may be a good alternative method for TT training, compared with conventional methods such as apprenticeship and animal skills laboratory. However, there is insufficient evidence supporting use of a simulator. The aim of this study is to determine whether training with medical simulator is associated with faster TT process, compared to conventional training without simulator. METHODS: This is a simulation study. Eligible participants were emergency medicine residents with very few (≤3 times) TT experience. Participants were randomized to two groups: the conventional training group, and the simulator training group. While the simulator training group used the simulator to train TT, the conventional training group watched the instructor performing TT on a cadaver. After training, all participants performed a TT on a cadaver. The performance quality was measured as correct placement and time delay. Subjects were graded if they had difficulty on process. RESULTS: Estimated median procedure time was 228 seconds in the conventional training group and 75 seconds in the simulator training group, with statistical significance (P=0.040). The difficulty grading did not show any significant difference among groups (overall performance scale, 2 vs. 3; P=0.094). CONCLUSION: Tube thoracostomy training with a medical simulator, when compared to no simulator training, is associated with a significantly faster procedure, when performed on a human cadaver.
