Response to the COVID-19 Outbreak in The Emergency Department Designed for Emerging Infectious Diseases in Korea / 감염과화학요법

Background@#According to the recent coronavirus disease 2019 (COVID-19) pandemic experience, many emergency departments experience difficulties in responding to emerging infectious diseases and this has led to a public health crisis. Our emergency department (ED) is designed to respond to mass outbreaks of infection. Three major preparations were taken to respond to infectious disease; first, to improve the emergency department facilities;second, to created programs to respond to each phase of an epidemic of COVID-19; lastly, to implemented education and training to promote the safety of medical staff. We would like to share the actual responses and statistics of patients visiting emergency department during COVID-19 periods of pandemic. @*Materials and Methods@#This research was conducted through a retrospective chart analysis provided by a public medical center with 502 beds since the first report of a COVID-19 confirmed case on January 19, 2020 to June 15, 2020 in Seoul, the capital of Korea. Our emergency department was designed based on Korean Regional Emergency Center Facility Standards, and modified throughout each phases of COVID-19 outbreak. Patients suspected to be infectious are screened in the triage, separating them from general patients, and then receive isolation treatment in isolated wards. @*Results@#A total of 4,352 patients visited the ED. 3,202 screenings were conducted with 5 confirmed cases. Another 1,150 patients were treated with general emergent symptoms.There were no problems such as closure of the emergency department or isolation of medical staff while managing COVID-19 confirmed patients. @*Conclusion@#Improving emergency department facilities, create an operational program to respond to each phase of COVID-19 outbreak and implement educational programs enabled large number of screening tests and hospitalization for COVID-19 suspected patients while maintaining general medical services. Research in emergency department designs and operational programs should increase to combine research data with better ideas to respond not only during regular periods but also during periods of pandemic.

Spatio-temporal trend of patients with syncope visiting the emergency department: a single-center, retrospective observational study

Objective@#This study examined the frequency of emergency department visits for syncope according to the day, week, and month. The frequency of syncope associated with holidays and the locations was also investigated. @*Methods@#A retrospective study was performed on the frequency of patients discharged from the emergency department with a diagnosis of syncope from July 2016 to June 2017. Each 24-hour period was analyzed in four-hour intervals, and the frequency of occurrence was calculated for weekly and monthly time frames. In addition, the frequency of syncope associated with holidays and the locations where syncope occurred were analyzed for any possible trends. @*Results@#For the 259 patients in this study, the frequency of the reflex syncope was significantly higher between 6 and 10 am (P=0.011), and showed a decreasing trend since that period (P=0.006). The number of reflex syncope visits on Mondays was significantly higher than on the other days (P<0.001) and a decreasing trend after Monday toward the weekend (P=0.023). A significant difference in the frequency of syncope associated with holidays was observed: 0.48 on weekdays, excluding the day after a holiday; 0.37 on a holiday; and 0.92 on the day after a holiday (P<0.001). Almost half of the reflex syncope events (44.3%) occurred in the subway. @*Conclusion@#The frequency of syncope was highest in the morning. In addition, reflex syncope showed a higher frequency on the day after a holiday, and the incidence was higher in the subway.

Clinical analysis of rabies post-exposure prophylaxis for animal bite in emergency department

OBJECTIVE: This study examined patients who visited the emergency department of a national medical center equipped with rabies vaccine and rabies immunoglobulin to confirm whether the treatment for rabies vaccination was appropriate in the emergency department. METHODS: This was a retrospective study that included 397 patients from January 1, 2014, to October 31, 2017. The patients finally diagnosed with animal bites according to the International Classification of Diseases, 10th revision code, at emergency department were collected. RESULTS: Most of the patients were 20–30 years old. Most of them were bitten by a dog, especially in the upper limb. Only 84% of patients who met the domestic rabies post-exposure prophylaxis (PEP) criteria were vaccinated. Patients who did not meet the criteria, approximately 22.3%, were also vaccinated. Complications after vaccination included clinical symptoms, such as headache, numbness, mild itching, and heating sensation. CONCLUSION: Rabies is a disease that can be prevented through PEP. Rabies PEP is relatively expensive and difficult to vaccinate easily, so it is desirable to subdivide the existing domestic rabies PEP guidelines into reality. Emergency physicians should know the proper rabies vaccination criteria and vaccinate patients only if necessary. This will help reduce medical resources and the complications of rabies vaccinations.

Cervical collar makes difficult airway: a simulation study using the LEMON criteria

OBJECTIVE: Endotracheal intubation is extremely difficult to perform in patients wearing a cervical collar for a head and neck injury. Therefore, we analyzed actual measurements using the look externally, evaluate 3-3-2, Mallampati score, obstruction, and neck mobility (LEMON) criteria before and after cervical collar application to investigate the causes of a difficult airway. METHODS: This simulation study was performed in 76 healthy volunteers. We measured the mouth opening, modified Mallampati classification, and neck extension before and after cervical collar application. RESULTS: The mean inter-incisor distance significantly decreased from 4.3 to 2.6 cm (P < 0.001). Fifty-seven participants classified as I and II were newly classified as III and IV according to the modified Mallampati classification after cervical collar application (16% to 91%). The angles of neck extension significantly decreased from 44° to 22° after cervical collar application (P < 0.001). Before cervical collar application, our simulations predicted that 14 of 76 participants (18%) would have a difficult airway, whereas after cervical collar application, 76 of 76 (100%) were predicted to have a difficult airway. CONCLUSION: All values for the LEMON criteria (mouth opening, modified Mallampati classification, and neck extension) worsened significantly after cervical collar application. Additionally, a difficult airway was predicted in all participants after cervical collar application.
