3D printed surveyed restoration and metal framework in removable dentures: A case report / 대한치과보철학회지

Computer-aided design–computer-aided manufacturing technology has been widely used in the manufacture of fixed prostheses including implants, but in the case of removable dentures, the analog method is still being used due to the errors such as a lack of fusion and over-fusion in selective laser meting process. With the recent development of CAD software, virtual surveying and framework design are made possible, and the designed file can be manufactured by milling or 3D printing. It replace the analog method of waxing and denture curing process and also can reduce the production time and cost. Therefore, this case is reported because good clinical results were obtained by digitally surveying on CAD software to produce a surveyed metal restoration and framework on maxillary and mandibular removable dentures.

Increased Prehospital Emergency Medical Service Time Interval and Nontransport Rate of Patients With Fever Using Emergency Medical Services Before and After COVID-19 in Busan, Korea

Background@#In Korea, patients with fever have been preemptively isolated to isolation beds in the emergency department (ED) since the coronavirus disease 2019 (COVID-19) pandemic began. However, isolation beds were not always available, and transport delays or failure (nontransport), especially for infants, were reported in the media. Few studies have focused on delays and failure in transporting fever patients to the ED. Therefore, this study aimed to examine and compare the emergency medical service (EMS) time interval and nontransport rate of patients with fever using EMSs before and after COVID-19. @*Methods@#This retrospective observational study analyzed the prehospital EMS time interval and nontransport rate of fever patients who contacted EMSs in Busan, South Korea, from March 1, 2019 to February 28, 2022, using emergency dispatch reports. All fever patients (≥ 37.5°C) who contacted EMSs during this study were included. The EMS time interval was defined as the time between the patient’s EMS call and ED arrival time. Nontransport was defined as a case recorded as not being transported in the emergency dispatch reports.The study population of 2019 was compared to the population of 2020 and 2021 with the independent t-test, Mann-Whitney U test, and χ 2 test. As a subgroup, the EMS time intervals and nontransport rates of infants with fever were compared before and after COVID-19. @*Results@#A total of 554,186 patients accessed the EMS during the study period, and 46,253 patients with fever were included. The EMS time interval (mean ± standard deviation, minutes) of fever patients was 30.9 ± 29.9 in 2019, 46.8 ± 127.8 in 2020 (P < 0.001) and 45.9 ± 34.0 in 2021 ( P < 0.001). The nontransport rate (%) was 4.4 in 2019, 20.6 in 2020 (P < 0.001), and 19.5 in 2021 (P < 0.001). For infants with fever, the EMS time interval was 27.6 ± 10.8 in 2019, 35.1 ± 15.4 in 2020 (P < 0.001), and 42.3 ± 20.5 in 2021 (P < 0.001), and the nontransport rate (%) was 2.6 in 2019, 25.0 in 2020, and 19.7 in 2021. @*Conclusion@#After the emergence of COVID-19, in Busan, the EMS time interval of fever patients was delayed, and approximately 20% of fever patients were not transported.However, infants with fever had shorter EMS time intervals and higher nontransport rates than the overall study population. A comprehensive approach, including prehospital and hospital ED flow improvements, is required beyond increasing the number of isolation beds.

Analysis of emergency residents health status and affected factors by 2019 Korean Emergency Medicine Resident Survey (KEMRS)

Objective@#Emergency medicine residents are expected to exhibit a poor health status due to excessive working hours and high stress. Because much of patient care depends on them, their health conditions will have a significant impact on patient outcomes. Our study was designed to analyze the health status of emergency medicine residents and the affecting factors using the 2019 Korean Emergency Medicine Residents Survey (KEMRS) results. @*Methods@#The study evaluated the self-rated health-defined percentage of responders who thought they were in good health. Based on this response, the influencing factors were categorized statistically. These factors included personal characteristics, lifestyle (drinking, smoking, eating, sleeping, and exercise), and emotional stress. @*Results@#Of a total of 384 respondents, 176 (46%) thought they were in good health. Participants who perceived themselves to be unhealthy included residents who were married, female, and those in the 3rd grade. Drinking and smoking were not perceived to affect health status, but regular exercise and proper eating patterns were seen to be positive influencing factors. Daytime sleepiness, depressive moods, and personal well-being were correlated with health status. @*Conclusion@#While personal characteristics and emotional problems cannot be changed easily, lifestyle changes can be made for better health. The health conditions of emergency residents have not been considered a matter of importance thus far. To overcome their health problems, responsible improvements in schedules and a program of long-term follow-ups need to be implemented, followed by training programs.

Analysis of Factors Affecting Emergency Physicians’ Attitudes toward Deceased Organ & Tissue Donation

Background@#This study aimed to investigate differences in knowledge, and attitudes toward deceased organ and tissue donation of emergency physicians. Additionally, we analyzed factors affecting the attitudes toward deceased organ and tissue donation. @*Methods@#We conducted a survey of specialists and residents registered with the Korean Society of Emergency Medicine in December 2020. The respondents’ sex, age, position, personal registration for organ donation, experience of soliciting organ donation, participation in related education, knowledge, and attitude about brain death organ donation, and attitude toward stopping life-sustaining treatments were investigated.According to the characteristics of the respondents (specialists or residents, experience and education on organ and tissue donation), their knowledge and attitude toward deceased organ donation were compared. Stepwise hierarchical multiple regression analysis was used to investigate the factors affecting the attitudes toward deceased organ and tissue donation. @*Results@#Of the total 428 respondents, there were 292 emergency medicine specialists and 136 medical residents. Specialists and those who registered or wished to donate organs had higher knowledge and attitude scores regarding deceased organ and tissue donation.Those who had experience recommending organ and tissue donation more than 6 times had higher knowledge scores on deceased organ and tissue donation and higher overall scores in attitude. Those who received education from the Korean Organ Donation Agency had higher knowledge scores. Specialists, and those who wished to donate or had registered as organ donors and had a higher life-sustaining treatment attitude score and knowledge about deceased organ and tissue donation, had more positive attitudes toward deceased organ and tissue donation. @*Conclusion@#For more potential deceased organ and tissue donors to be referred for donation, there should be continuous education for emergency physicians on brain-dead organ and tissue donation-related knowledge and procedures. In addition, institutional or systematic improvements that can lead to organ donation when deciding on the withdrawal of life-sustaining treatment should be considered.

Emergency Physicians’ Experience of Communication About Brain-Death Organ and Tissue Donation / 의료커뮤니케이션

Background@#: Emergency physicians are increasingly participating in brain-death organ tissue donation (OTD).It is difficult communication to inform family members about suspected brain-death and potential donor.This study sought to explore the experiences and communication of emergency physicians in brain-death OTD. @*Methods@#: This is a qualitative study that interviewed 10 experienced emergency physicians with brain-death OTD and analyzed the data by thematic analysis method. @*Results@#: The study revealed 20 subthemes and 5 themes; 1) Families who are invited to donate organs make decisions after long periods of consideration by the entire family, 2) It is uncomfortable to recommend organ donation, 3) Explaining and obtaining consent is ‘the hardest job’ for the attending physician, 4) The way the attending physician does ‘the hardest job’ is by explaining, 5) Passively solicit donation. @*Conclusion@#: The experienced emergency physicians with brain-death OTD were using methods of communication to understand and sympathized with the family members and had abundant experiences. The findings of this study will help inexperienced emergency physicians with brain-death OTD.

The Comparison of Emergency Medical Service Responses to and Outcomes of Out-of-hospital Cardiac Arrest before and during the COVID-19 Pandemic in an Area of Korea

Background@#Since the declaration of the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 has affected the responses of emergency medical service (EMS) systems to cases of out-of-hospital cardiac arrest (OHCA). The purpose of this study was to identify the impact of the COVID-19 pandemic on EMS responses to and outcomes of adult OHCA in an area of South Korea. @*Methods@#This was a retrospective observational study of adult OHCA patients attended by EMS providers comparing the EMS responses to and outcomes of adult OHCA during the COVID-19 pandemic to those during the pre-COVID-19 period. Propensity score matching was used to compare the survival rates, and logistic regression analysis was used to assess the impact of the COVID-19 pandemic on the survival of OHCA patients. @*Results@#A total of 891 patients in the pre-COVID-19 group and 1,063 patients in the COVID-19 group were included in the final analysis. During the COVID-19 period, the EMS call time was shifted to a later time period (16:00–24:00, P < 0.001), and the presence of an initial shockable rhythm was increased (pre-COVID-19 vs. COVID-19, 7.97% vs. 11.95%, P = 0.004). The number of tracheal intubations decreased (5.27% vs. 1.22%, P < 0.001), and the use of mechanical chest compression devices (30.53% vs. 44.59%, P < 0.001) and EMS response time (median [quartile 1-quartile 3], 7 [5–10] vs. 8 [6–11], P < 0.001) increased. After propensity score matching, the survival at admission rate (22.52% vs. 18.24%, P = 0.025), survival to discharge rate (7.77% vs. 5.52%, P = 0.056), and favorable neurological outcome (5.97% vs. 3.49%, P < 0.001) decreased. In the propensity score matching analysis of the impact of COVID-19, odds ratios of 0.768 (95% confidence interval [CI], 0.592–0.995) for survival at admission and 0.693 (95% CI, 0.446–1.077) for survival to discharge were found. @*Conclusion@#During the COVID-19 period, there were significant changes in the EMS responses to OHCA. These changes are considered to be partly due to social distancing measures. As a result, the proportion of patients with an initial shockable rhythm in the COVID-19 period was greater than that in the pre-COVID-19 period, but the final survival rate and favorable neurological outcome were lower.

Agreement between medical students’ peer assessments and faculty assessments in advanced resuscitation skills examinations in South Korea / 보건의료교육평가

Purpose@#In medical education, peer assessment is considered to be an effective learning strategy. Although several studies have examined agreement between peer and faculty assessments regarding basic life support (BLS), few studies have done so for advanced resuscitation skills (ARS) such as intubation and defibrillation. Therefore, this study aimed to determine the degree of agreement between medical students’ and faculty assessments of ARS examinations. @*Methods@#This retrospective explorative study was conducted during the emergency medicine (EM) clinical clerkship of fourth-year medical students from April to July 2020. A faculty assessor (FA) and a peer assessor (PA) assessed each examinee’s resuscitation skills (including BLS, intubation, and defibrillation) using a checklist that consisted of 20 binary items (performed or not performed) and 1 global proficiency rating using a 5-point Likert scale. The prior examinee assessed the next examinee after feedback and training as a PA. All 54 students participated in peer assessment. The assessments of 44 FA/PA pairs were analyzed using the intraclass correlation coefficient (ICC) and Gwet’s first-order agreement coefficient. @*Results@#The PA scores were higher than the FA scores (mean±standard deviation, 20.2±2.5 [FA] vs. 22.3±2.4 [PA]; P<0.001). The agreement was poor to moderate for the overall checklist (ICC, 0.55; 95% confidence interval [CI], 0.31 to 0.73; P<0.01), BLS (ICC, 0.19; 95% CI, -0.11 to 0.46; P<0.10), intubation (ICC, 0.51; 95% CI, 0.26 to 0.70; P<0.01), and defibrillation (ICC, 0.49; 95% CI, 0.23 to 0.68; P<0.01). @*Conclusion@#Senior medical students showed unreliable agreement in ARS assessments compared to faculty assessments. If a peer assessment is planned in skills education, comprehensive preparation and sufficient assessor training should be provided in advance.

Comparing the cut score for the borderline group method and borderline regression method with norm-referenced standard setting in an objective structured clinical examination in medical school in Korea / 보건의료교육평가

Purpose@#Setting standards is critical in health professions. However, appropriate standard setting methods do not always apply to the set cut score in performance assessment. The aim of this study was to compare the cut score when the standard setting is changed from the norm-referenced method to the borderline group method (BGM) and borderline regression method (BRM) in an objective structured clinical examination (OSCE) in medical school. @*Methods@#This was an explorative study to model the implementation of the BGM and BRM. A total of 107 fourth-year medical students attended the OSCE at 7 stations for encountering standardized patients (SPs) and at 1 station for performing skills on a manikin on July 15th, 2021. Thirty-two physician examiners evaluated the performance by completing a checklist and global rating scales. @*Results@#The cut score of the norm-referenced method was lower than that of the BGM (P<0.01) and BRM (P<0.02). There was no significant difference in the cut score between the BGM and BRM (P=0.40). The station with the highest standard deviation and the highest proportion of the borderline group showed the largest cut score difference in standard setting methods. @*Conclusion@#Prefixed cut scores by the norm-referenced method without considering station contents or examinee performance can vary due to station difficulty and content, affecting the appropriateness of standard setting decisions. If there is an adequate consensus on the criteria for the borderline group, standard setting with the BRM could be applied as a practical and defensible method to determine the cut score for OSCE.

Emergency medicine residents’ needs assessment for education and training using nationwide survey

Objective@#This study was conducted to identify the needs assessment for education and training of emergency medicine (EM) residents. @*Methods@#The results of a national survey of EM residents of the Korean Society of Emergency Medicine in 2019 were used. Education was one of the five categories in the survey. The preferred learning methods and their perceived importance and ability to perform in nine competencies were assessed. The Borich’s needs assessment model was used to analyze their needs. @*Results@#Among 591 EM residents, 382 responded, and 371 responses were finally analyzed. Regarding the learning methods, junior residents preferred in-hospital conferences, staff lectures, internet resources, and textbooks. Overall, medical knowledge and procedural skills were the most important, and research was less important to recognize. Medical knowledge showed the highest rank in the needs assessment in all years, and ethics and professionalism showed the lowest ranks. The needs for procedural skills were higher in junior years but lower in senior years. @*Conclusion@#These results will form the basis for the design of training programs to meet the educational needs of EM residents for each grade. Furthermore, an analysis of the educational needs should be done periodically according to the changes and demands of the times.

Experience of essay during the clinical clerkship in emergency medicine and inter-rater reliability on essay

Objective@#An essay test is difficult to carry out because of the effort for hand scoring and the concerns about inter-rater reliability, even though the use of a rubric can increase inter-rater reliability. This study examined the feasibility of an essay test in medical school students and whether the use of a rubric increases inter-rater reliability. @*Methods@#An essay test was given to 51 undergraduate students in the third grade of emergency medicine clinical clerkship. Three raters assessed the essay test independently with a prepared rubric immediately after the test. They then did the same essay test without a rubric three months later. The researchers compared the Pearson’s correlation coefficients between raters. The researchers analyzed the validity comparing the correlation coefficient between the essay test and previous multiple-choice questions (MCQ) and feasibility by acceptance. @*Results@#Fifty-one students took the essay test. The Pearson’s correlation coefficient using rubric between raters 1 and 2, 1 and 3, and 2 and 3 were 0.898 (P<0.001), 0.896 (P<0.001), and 0.856 (P<0.001), respectively. Without a rubric, the correlation coefficients were 0.838 (P<0.001), 0.888 (P<0.001), and 0.824 (P<0.001), respectively. The new essay test showed a positive correlation (0.367) with the previous MCQ, and the evidence for validity and feasibility was acceptable. @*Conclusion@#In this study, the rubric did not increase the inter-rater reliability of the essay test. On the other hand, the inter-rater reliability was higher than 0.8, even without a rubric. In addition, the essay test showed evidence of validity and feasibility.

A survey on the perception of emergency medical services (EMS) providers and medical directors toward EMS provider’s field skill proficiency

Objective@#This study aimed to investigate the perception of emergency medical service (EMS) providers and medical directors toward the field skill proficiency of EMS providers. We further examined differences in perception according to the certification and hospital career of individuals. @*Methods@#This survey was conducted enrolling all active EMS providers in Busan, Ulsan, and Gyeongnam, as well as emergency physicians who participated in direct medical direction. Pre-developed questionnaires were sent as text messages to individual EMS providers and emergency physicians using an internet-based survey tool (Google Forms).Questionnaires were composed of 25 items in 7 categories: “airway management”, “ventilatory support”, “circulatory support”, “field assessment and management of trauma patients”, “field assessment and management of patients with chest pain”, “field assessment and management of patients with neurologic symptoms”, and “other items”. The response was based on a five-point Likert scale, where 0 score indicated no experience at all. @*Results@#The questionnaire was distributed to 1,781 EMS providers and 52 medical directors; of these, 1,314 (73.7%) EMS providers and 34 (65.3%) medical directors completed the survey. EMS providers rated themselves as above average (3 points) for most of the questions. However, the majority responded that they had no experience or low proficiency in endotracheal intubation and prehospital delivery (median 2; interquartile range [IQR], 0-3). Conversely, medical directors assessed the EMS provider’s proficiency as above average in use of I-gel, recognition of hypoglycemia, field management of trauma patients, use of oropharyngeal and nasopharyngeal airway, use of laryngeal mask airway, and optimal oxygen supply (median, 4; IQR, 3-4), but responded with low scores for most other questions. Based on the EMS provider certification, nurses scored themselves more proficient than level-1 emergency medical technicians (EMTs) for intravenous access (P<0.001), whereas level-1 EMTs recognized themselves more proficient than nurses for endotracheal intubation (P<0.001), use of Magill forceps (P=0.004), and pediatric cardiopulmonary resuscitation (P<0.001). @*Conclusion@#This study recognized the discrepancies in the perception of EMS provider’s field skill proficiency, as perceived by EMS providers and medical directors, and between level-1 EMTs and nurses. We propose that regional EMS authorities need to make persistent efforts to narrow these perception gaps through effective educational programs for EMS providers and medical directors.

A survey of work status of a local emergency medical services (EMS) personnel and the perception between EMS personnel and medical directors about on-line medical oversight

Objective@#This study investigated the current work status of emergency medical services (EMS) personnel and the differences in perception between EMS personnel and medical directors (MD) regarding on-line medical oversight in a province. @*Methods@#A total of 1,781 EMS personnel and 51 medical directors were surveyed. The questionnaire consisted of the basic demographic data, work status, perception of on-line medical oversight, and the upcoming national pilot project of the expanding firefighter EMS personnel’s clinical scope. The survey was conducted from May 17 to 27, 2019. @*Results@#The response rates for EMS personnel and MD were 73.7% and 65.3%, respectively. Of the local EMS personnel, 86.8% were male. The average age and field career was 33.5±6.2 years and 50 months, respectively. The proportion of nurse and 1st-grade emergency medical technicians were 30.6% and 35.7%. The EMS personnel and MD answered ‘on-scene basic life support’ and ‘patient’s refusal of transport’, respectively, as the most unnecessary medical oversight. Both responded to the main problem of current medical oversight as ‘request for unnecessary medical oversight.’ EMS personnel responded that all items in the national pilot project of expanding firefighter EMS personnel’s clinical scope would be helpful, while MD reported that only ‘use of epinephrine in anaphylactic patient’ and ‘use of pre-hospital 12 lead electrocardiogram in chest pain patient’ would helpful (P<0.01). @*Conclusion@#There was a certain difference in perception of the most unnecessary medical oversight and the upcoming national pilot project of expanding the clinical scope of firefighter EMS personnel between EMS personnel and MD.

How many emergency medicine residents reselect their specialty if they could?

Objective@#The 2019 Korean Emergency Medicine Residents Survey (KEMRS) is the first survey by the Korean Society of Emergency Medicine (KSEM) on the comprehensive satisfaction of their residents. Satisfaction is important not only for the personal well-being of the residents but also for patient safety. @*Methods@#A total of 622 emergency medicine residents were surveyed, using both a paper and email questionnaire from May to August of 2019. Factors related to satisfaction were analyzed. @*Results@#Of the responders, 66% said they would reapply for the emergency specialty and 51% said that they would reselect the same training hospital. The group of residents who said they would choose emergency medicine again felt that their expectations had been met and that they were comfortable with the choice of the specialty. They felt that the factors of satisfaction with their shift schedule and personal health played a more important role in their reselection of the training hospital than the workload. @*Conclusion@#The satisfaction levels of the Korean emergency residents were low. Thus, training hospitals should provide a reasonable working environment to increase their satisfaction. Also, it is important to create an environment where residents can feel rewarded and proud of the work they do.

Clinical performance of medical students in Korea in a whole-task emergency station in the objective structured clinical examination with a standardized patient complaining of palpitations / 보건의료교육평가

This study assessed the clinical performance of 150 third-year medicalstudents in Busan, Korea in a whole-task emergency objective structured clinical examination station that simulated a patient with palpitations visiting the emergency department. The examination was conducted from November 25 to 27, 2019. Clinical performance was assessed as the number and percentage of students who performed history-taking (HT), a physical examination (PE), an electrocardiography (ECG) study, patient education (Ed), and clinical reasoning (CR), which were items on the checklist. It was found that 18.0% of students checked the patient’s pulse, 51.3% completed an ECG study, and 57.9% explained the results to the patient. A sizable proportion (38.0%) of students did not even attempt an ECG study. In a whole-task emergency station, students showed good performance on HT and CR, but unsatisfactory results for PE, ECG study, and Ed. Clinical skills educational programs for subjected student should focus more on PE, timely diagnostic tests, and sufficient Ed.

They felt that the factors of satisfaction with their shift schedule and personal health played a more important role in their reselection of the training hospital than the workload. @*Conclusion@#The satisfaction levels of the Korean emergency residents were low. Thus, training hospitals should provide a reasonable working environment to increase their satisfaction. Also, it is important to create an environment where residents can feel rewarded and proud of the work they do.

Clinical performance of medical students in Korea in a whole-task emergency station in the objective structured clinical examination with a standardized patient complaining of palpitations / 보건의료교육평가

This study assessed the clinical performance of 150 third-year medicalstudents in Busan, Korea in a whole-task emergency objective structured clinical examination station that simulated a patient with palpitations visiting the emergency department. The examination was conducted from November 25 to 27, 2019. Clinical performance was assessed as the number and percentage of students who performed history-taking (HT), a physical examination (PE), an electrocardiography (ECG) study, patient education (Ed), and clinical reasoning (CR), which were items on the checklist. It was found that 18.0% of students checked the patient’s pulse, 51.3% completed an ECG study, and 57.9% explained the results to the patient. A sizable proportion (38.0%) of students did not even attempt an ECG study. In a whole-task emergency station, students showed good performance on HT and CR, but unsatisfactory results for PE, ECG study, and Ed. Clinical skills educational programs for subjected student should focus more on PE, timely diagnostic tests, and sufficient Ed.
