Purpose: Emergency room(ER) is the first place to enter a hospital where patients who might have been infected with contagious disease. Therefore, ER should be designed with infection control in mind. Researchers examined hospital ER layouts to identify layout design that support infection control. Methods: This study analyzed the hospital ER layout of Korean and other hospitals abroad. Researchers focused on route of incoming patients who potentially have infectious disease. Crossing of this route with other routes such as for imaging and testing should be avoided for infection control. Results: There were certain hospital ERs with better control of infection related incidents. ER floor plan layout is analyzed about allocation of key functions with movement routes for each role such as patients and medical staff in mind. To identify layout strategies for ER functions researchers simplified the routes in ER into diagrams. Layout options show that bypassing infection suspected routes over other routes is possible. Implications: Hospitals can control infection easier when they adopt strategic ER layout identified in this study.
Sepsis is conceptually defined as life-threatening organ dysfunction that is caused by a dysregulated host response to infection. Although there has been significant advancement in recent decades in defining and understanding sepsis pathology, clinical management of sepsis is challenging due to difficulties in diagnosis, a lack of reliable prognostic biomarkers, and treatment options that are largely limited to antibiotic therapy and fundamental supportive measures. The lack of reliable diagnostic and prognostic tests makes it difficult to triage patients who are in need of more urgent care. Furthermore, while the acute inpatient treatment of sepsis warrants ongoing attention and investigation, efforts must also be directed toward longer term survival and outcomes. Sepsis survivors experience incomplete recovery, with long-term health impairments that may require both cognitive and physical treatment and rehabilitation. This review summarizes recent advances in sepsis prognosis research and discusses progress made in elucidating the underlying causes of prolonged health deficits experienced by patients surviving the early phases of sepsis.

Background: Ovarian cancer is the most common cancer cause of gynecologic cancer deaths. In order to increase the likelihood of patient survival through primary operation by gyneco-oncologists, an appropriate algorithm for referral is considered here. Materials and Methods: Suspicious adnexal mass cases including ovarian malignancy probability score-1 (OMPS1) scores between 2.3-3.65 are re-evaluated by OMPS2. Sensitivity and specificity of each score were determined. Results: Sensitivity and specificity with a 3.82 score of OMPS2 in the studied subgroup (OMPS1 scores between 2.3-3.65) were 64% and 76.9% respectively. Conclusions: Management of OMPS1 scores of below 2.3 with sensitivity of 100% and above 3.65 with specificity of 72.9% is clear. In the subgroup of cases with OMPS1 score between 2.3-3.65, OMPS2 is helpful for triage with a cutoff score of 3.82.
Purpose: The purpose of the study is to suggest the main functions and implications of public hospitals to effectively respond to the future epidemic crisis based on analyzing the accessibility to designated Coronavirus Disease 2019 (COVID-19) medical institutions of Seoul and examining the main features of the quarantine of Seoul municipal hospitals. Method: To analyze the response and function of Seoul municipal hospitals, we reviewed the Infectious Disease Control and Prevention ACT, 258 articles of Seoul Metropolitan Government press releases from January to the end of April, 48 articles of Seoul Metropolitan Government's daily newsletters, 2019 Health Bureau Budget report. We also referred to internal data of Seoul Children's Hospital, Seoul Seobuk Hospital, and Seoul Eunpyeong Hospital during the same period. Besides, the accessibility to medical institutions was analyzed by using the COVID-19 data which was announced daily basis. Results: The accessibility of COVID-19 patients living in the Southeastern part of Seoul to a medical institutions was 16.2km on a distance basis, and it was the lowest accessibility among four regions of Seoul since it took about 40 minutes by car. On the other hand, patients living in the Northeast part had the highest accessibility, as the access to medical institutions was 10.7km and 27 minutes by car. Also, the main functions of the municipal hospital of Seoul against COVID-19 were to shift the public hospital function to COVID-19 patients only hospitals, to perform the epidemiological investigation by medical doctors, and to support the operation of self-isolation facilities, community treatment centers and triage rooms of community health centers. Conclusion: Through the experience of COVID-19, we suggested that the functions of public hospitals will be reorganized as the reinforcement of infectious disease treatment and mental health for quarantined patients, cooperation with private hospitals, supporting for strengthening community health capacity and preparation for another epidemic.

Nurses use a nursing process. that is a scientific approach method. in order to understand the clients' condition and to solve their problems. Professional nurses have accepted the nursing process as a standard framework for nursing activities, and the first step of the nursing process is nursing assessment. The purpose of this study was to develop a nursing assessment tool for emergency patients. Assessment is a first step in the nursing process, and scientific assessment helps to better understand the patients. Thus the development of an assessment tool for emergency patients will improve of nursing quality and advance to efficacy of emergency room(ER) management. The study involved the development of a conceptual framework, preliminary tool, content validity verification process. and reliability verification process. The conceptual framework was developed through a review of the literature. and preliminary tool was developed from the conceptual framework that based on care flow sheet' developed James A. Haley. The preliminary tool was evaluated for validity and reliability by seven experts, one ER nurse manager, two ER head nurses, two emergency medicine doctors. and two ER charge nurses and by ten nurses with one to five year careers in ER nursing. The results of this study was as follows 1. The conceptual framework which was developed was composed of three parts. They were triage criteria, first assessment and secondary assessment. 2. The preliminary tool which was developed had 31 items based on the conceptual framework. 3. To test expert validity a 4-point scale was used. items which had gained 3-4 points from six persons of the seven experts were selected. All 31 items from the preliminary tool were selected. 4. The reliability test was done by ten nurses educated in the use of the assessment tool. Two pairs of nurses simultaneously assessed the same patients. A total agreement percentile was calculated and result was 87.3% agreement. 5. After the validity and reliability testing. the final emergency patient nursing assessment tool was finalized with 31 items. and a check-list for the responses. This study concludes that the tool which was developed is both valid and reliable will advance quality care for emergency patients. This emergency nursing assessment tool was also found to be an adequate tool for assessment of emergency patients.
Objective We conducted a study to validate the effectiveness of the Korean criteria for trauma team activation (TTA) and compared its results with a two-tiered system. Methods This observational study was based on data from the Korean Trauma Data Bank. Within the study period, 1,628 trauma patients visited our emergency department, and 739 satisfied the criteria for TTA. The rates of overtriage and undertriage in the Korean one-tiered system were compared with the two-tiered system recommended by the American College of Surgery-Committee on Trauma. Results Most of the patient's physiologic factors reflected trauma severity levels, but anatomical factors and mechanism of injury did not show consistent results. In addition, while the rate of overtriage (64.4%) was above the recommended range according to the Korean criteria, the rate of undertriage (4.0%) was within the recommended range. In the simulated two-tiered system, the rate of overtriage was reduced by 5.5%, while undertriage was increased by 1.8% compared to the Korean activation system. Conclusion The Korean criteria for TTA showed higher rates of overtriage and similar undertriage rates compared to the simulated two-tier system. Modification of the current criteria to a twotier system with special considerations would be more effective for providing optimum patient care and medical resource utilization.
Background: The purpose of this study was to the impact of the coronavirus disease 2019 (COVID-19) outbreak on emergency departments (EDs) in patients under the age of 18 years with respiratory disease. Also, we analyzed similarities and differences in patients including revisit before and after the COVID-19 outbreak. Methods: This study population was respiratory patients under the age of 18 years who visited all 403 EDs in Korea between January 1st, 2019 and December 31st, 2020, using the National Emergency Department Information System Database. The primary outcome was the number of respiratory patients according to age, sex, the type of EDs, season, Korean Triage and Acuity Scale (KTAS) levels, the result of ED, and length of stay. The secondary outcome was the number of revisit respiratory patients within 72 hours. We calculated the risk-adjusted revisit rates according to the KTAS level using a multiple logistic regression model. Results: The number of ED visits decreased from 274,526 in 2019 to 79,007 in 2020; this number was 71.2% lower than that before COVID-19. In spring 2020, this number was 90.1% lower than during the same period in 2019. For the revisit rate in the study population, the adjusted odds ratio (95% confidence interval) was 1.22 (1.05-1.41) in 2019 and 1.39 (1.07-1.81) in 2020. Conclusion: Implementing appropriate emergency care policies in severe respiratory patients would have contributed to improving the safety of reducing in revisit rate.

Survivability in a battle field is the most important aspect to the warriors. To analyze the survival effectiveness of warrior platform, the simulation via war-game model is an essential step in advance to the development of platform. In this study, Army Weapon effectiveness Analysis Model(AWAM) was utilized for analysis. Several weapon parameters were adjusted to apply the characteristics of warrior platform in some cases of the defense and survival system. Especially, adjusted triage possibility, probability of kill, fatality and accuracy were employed as parameters in the simulation program to evaluate the survival effectiveness of intelligent system based on the previous researches. In the future battle field or virtual space in the AWAM, the warrior platform intelligent system could react emergency treatment on time by expoiting the bio-information of man at arms. Considering the order of supply priority, special force was selected as operating troops and battle scenario without engagement was selected to measure accurate survival effectiveness. In conclusion, the survivability of defence and survival system of the warrior platform was about 1.47 times higher than that of current system.

Purpose: Stool exams are a useful tool for the early presumptive diagnosis of infectious bacterial diarrhea in the Emergency Department (ED). CT scans are often used to increase the physician's level of certainty and to facilitate patient triage by identifying the source of pain in most patients with an acute abdomen in the ED. This study was designed to investigate the correlation between stool exams and abdominal CT in patients with acute diarrhea visiting the ED. Methods: We conducted a retrospective study in the emergency department of a national university hospital from January 1, 2012 to June 30, 2013. The subjects consisted of 156 patients with acute diarrhea and abdominal pain who had stool exam results and abdominal CT findings. We divided the patients into three groups according to the stool exam results. Simultaneously, we evaluated their CT findings of the bowel and adjacent structures. Results: A total of 156 patients were enrolled. Frequency of abnormal CT findings showed statistically significant correlation with stool exams (p-value <0.001). Abnormal CT findings increased as WBCs and RBCs in stool increased (p-value <0.001). Conclusion: The stool exam was a statistically significant predictive variable in indirectly determining the severity of acute diarrhea and it showed correlation with the frequency of abnormal CT findings. It is suggested that stool exams can be used as a susceptible marker for predicting the probability of severe infectious colitis, and for making an early decision regarding close medical attention.

Purpose: To identify the prognostic factors that could influence survival and to compare prognoses of the patients with the number of the risk factors that might assist in the adequate management of hepatocellular carcinoma (HCC) patients with bone metastases that showed a heterogeneous range of survival. Materials and Methods: A total of 41 patients, treated with radiotherapy (RT) for bone metastases from HCC from 2014 to 2017, were enrolled retrospectively. Survival was determined by the Kaplan-Meier method from the start of the RT for metastatic bone lesions. Pre-RT clinical features were evaluated and their influences on survival were analyzed. The significant factors were considered to compare survivals according to the number of prognostic factors. Results: Median follow-up was 6.0 months (range, 0.5 to 47.0 months). The median overall survival was 6.5 months, and the 1-year and 2-year survival rates were 35.5% and 13.5%, respectively. Multivariate analysis revealed that the Child-Pugh class A group, alpha-fetoprotein increased more than 30 ng/mL, and HCC size of more than 5 cm were associated with worse overall survival. The median survivals in HCC with none, 1, 2, and 3 of the aforementioned risk factors were 19.5, 9.0, 2.5, and 1.0 months, respectively (p < 0.05). Conclusion: Our results show that the overall survivals were significantly different according to the number of the risk factors among HCC patients with bone metastases who showed various lengths of survival.
