Objective To analyze the research status of in situ simulation in the medical field and explore its hotspots and trends. Methods Relevant literature was searched in China National Knowledge Infrastructure and Web of Science core collection from the inception to February 2024.CiteSpace 6.3.R1 was used to analyze the authors,institutions,and keywords and draw visual knowledge maps. Results A total of 25 Chinese articles and 438 English articles were included.Only 14 English articles were from China.In Chinese articles,the authors with the largest number of articles were Dai Hengmao and Liu Shangkun,and the institution with the largest number of articles was Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.There was little cooperation between the authors and institutions.In English articles,the author and institution with the largest number of articles was Auerbach Marc and Yale University,respectively,and the cooperation between authors and institutions was close.Emergency medicine,emergency event handling,and on-the-job training were the keywords with high frequency in Chinese articles.Patient safety,medical education,and cardiac arrest were the keywords with high frequency in English articles.A total of 4 clusters were generated for Chinese keywords and 13 clusters for English keywords. Conclusions The application of in situ simulation in the medical field is still in the initial stage,and the development is not balanced at home and abroad.The number of articles published and the cooperation between authors and institutions in China obviously lags behind those abroad.Treatment and care of emergency critical patients,emergency event handling and skill training,identification of latent safety threats,improvement of readiness,and promotion of medical quality improvement are the future research hotspots and research trends in this field.

OBJECTIVE: To systematically summarize and analyze the project applications and funding in the field of Emergency and Critical Care Medicine by the Medical Science Department of the National Natural Science Foundation of China (NSFC) from 2010 to 2024, and to identify research hotspots and developmental trends, providing scientific references for the high-quality development of the Emergency and Critical Care Medicine in China. METHODS: Data on all project applications and funding in the field of Emergency and Critical Care Medicine (application code H16) from 2010 to 2024 were collected from the NSFC Grants System, including project application numbers, funding numbers and amounts, project categories, regional and affiliated institutions distributions. Keyword co-occurrence analysis was conducted using VOSviewer software to identify research hotspots, and results were presented using bar charts, pie charts, and Sankey diagrams. RESULTS: Over the past 15 years, the Emergency and Critical Care Medicine field of NSFC received 13 747 project applications and funded 1 781 projects, with a cumulative funding amount of 8.064 99 billion RMB. The annual number of applications increased from 296 in 2010 to 1 971 in 2024, representing an average annual growth rate of 40.42%. Similarly, the number of funded projects grew from 45 in 2010 to 175 in 2024, with an average annual growth rate of 20.63%, while annual funding rose from 20.01 million RMB in 2010 to 74.20 million RMB in 2024, reflecting an average annual growth rate of 19.34%. The majority of funded projects belonged to the General Program (774 projects), Young Scientists Fund (754 projects), and Regional Science Fund (163 projects), collectively accounting for 94.95% of total funded projects (1 691/1 781). Funding was concentrated in two primary research areas: Organ Dysfunction and Support (H1602, 751 projects) and Sepsis (H1601, 612 projects), together comprising 76.53% of total funded projects (1 363/1 781). The total number of funded projects (1 781 projects) in Emergency and Critical Care Medicine was fewer than the average across the subfields of Medical Science Department (4 181 projects). Shanghai (305 projects, 17.1%), Guangdong (222 projects, 12.5%), Jiangsu (154 projects, 8.6%), Zhejiang (149 projects, 8.4%), and Beijing (134 projects, 7.5%) ranked as the top five regions in terms of funded projects. Keyword co-occurrence analysis revealed that sepsis, organ injury, pulmonary injury and poisoning, and cardiopulmonary resuscitation were the main research hotspots in the field of Emergency and Critical Care Medicine over the past 15 years. CONCLUSION From 2010 to 2024, the NSFC funding for the field of Emergency and Critical Care Medicine has shown a significant upward trajectory, providing vital support for the rapid advancement of basic and applied research. This growth has played a crucial role in facilitating the high-quality development of Emergency and Critical Care Medicine in China.

This study evaluates a Massive Open Online Course (MOOC) on Emergency Medicine designed by iEM Education Project and Lecturio, using a validated checklist to assess its usability and user experience. The MOOC received a high score for cognitive connection (>4/5), in four components including interactivity, content and resources, media use, and instructional assessment. However, for learner guidance and support, the score was 2.75/5, indicating that the course did not provide clear instructions on how learners can get support or feedback from teachers when encountering problems in the course. For affective and functional connections, all components received a high overall mean score of more than 4/5. The course was impactful to the users who were in their early clinical years, as they were actively engaged and were motivated to complete the course. However, improvements should be made to better stimulate learning by improving learner feedback and providing space for collaborative learning online. Evaluation of MOOC applying the heuristics of usability and user experience identifies specific components of online learning course apart from rating the severity of acceptance or violation of instructional design principles. The information derived from usability and user experience studies can improve design and delivery of online courses.

The use of computed tomography (CT) in emergency departments has increased over several decades, as physicians increasingly depend on imaging for diagnoses. Patients and medical personnel are put at risk due to frequent exposure to and higher levels of radiation, with very little evidence of improvements in outcomes. Here, we explore why CT imaging has a tendency to be overused in emergency departments and the obstacles that medical personnel face in ensuring patient safety. The solution requires cooperation from all emergency care stakeholders as well as the continuous education of doctors on how CT scans help in particular cases.

The Emergency Medicine Recipes in Local Medicinals (鄕藥救急方, Hyang'yak Kugŭpbang) (c. 14th century) is known to be one of the oldest Korean medical textbooks that exists in its entirety. This study challenges conventional perceptions that have interpreted this text by using modern concepts, and it seeks to position the medical activities of the late Koryŏ Dynasty 高麗 (918–1392) to the early Chosŏn Dynasty 朝鮮 (1392–1910) in medical history with a focus on this text. According to existing studies, Emergency Medicine Recipes in Local Medicinals is a strategic compromise of the Korean elite in response to the influx of Chinese medical texts and thus a medical text from a “periphery” of the Sinitic world. Other studies have evaluated this text as a medieval publication demonstrating stages of transition to systematic and rational medicine and, as such, a formulary book 方書 that includes primitive elements. By examining past medicine practices through “modern” concepts based on a dichotomous framework of analysis — i.e., modernity vs. tradition, center vs. periphery, science vs. culture — such conventional perceptions have relegated Emergency Medicine Recipes in Local Medicinals to the position of a transitional medieval publication meaningful only for research on hyangchal 鄕札 (Chinese character-based writing system used to record Korean during the Silla Dynasty 新羅 [57 BC–935 AD] to the Koryŏ Dynasty). It is necessary to overcome this dichotomous framework in order to understand the characteristics of East Asian medicine. As such, this study first defines “medicine 醫”, an object of research on medical history, as a “special form of problem-solving activities” and seeks to highlight the problematics and independent medical activities of the relevant actors. Through this strategy (i.e., texts as solutions to problems), this study analyzes Emergency Medicine Recipes in Local Medicinals to determine its characteristics and significance. Ultimately, this study argues that Emergency Medicine Recipes in Local Medicinals was a problem-solving method for the scholar-gentry 士人層 from the late Koryŏ Dynasty to the early Chosŏn Dynasty, who had adopted a new cultural identity, to perform certain roles on the level of medical governance and constitute medical praxis that reflected views of both the body and materials and an orientation distinguished from those of the so-called medicine of Confucian physicians 儒醫, which was the mainstream medicine of the center. Intertwined at the cultural basis of the treatments and medical recipes included in Emergency Medicine Recipes in Local Medicinals were aspects such as correlative thinking, ecological circulation of life force, transformation of materiality through contact, appropriation of analogies, and reasoning of sympathy. Because “local medicinals 鄕藥” is understood in Emergency Medicine Recipes in Local Medicinals as referring to objects easily available from one's surroundings, it signifies locality referring to the ease of acquisition in local areas rather than to the identity of the state of Koryŏ or Chosŏn. As for characteristics revealed by this text's methods of implementing medicine, Korean medicine in terms of this text consisted largely of single-ingredient formulas using diverse medicinal ingredients easily obtainable from one's surroundings rather than making use of general drugs as represented by materia medica 本草 or of multiple-ingredient formulas. In addition, accessible tools, full awareness of the procedures and processes of the guidelines, procedural rituals, and acts of emergency treatment (first aid) were more important than the study of the medical classics, moral cultivation, and coherent explanations emphasized in categorical medical texts. Though Emergency Medicine Recipes in Local Medicinals can be seen as an origin of the tradition of emergency medicine in Korea, it differs from medical texts that followed which specializing in emergency medicine to the extent that it places toxicosis 中毒 before the six climatic factors 六氣 in its classification of diseases.

Damage control resuscitation is a relatively new resuscitative strategy for patients with severe traumatic hemorrhage. This strategy consists of permissive hypotension and early balanced transfusion, and transfers the patients to subsequent surgery. There is growing evidence on harms of excessive fluids. Since 2013, survival benefit of massive transfusion protocol has been proven in adults. Despite insufficient evidence, pediatric massive transfusion protocols are widely used in North American trauma centers. This review focuses on the concept of damage control resuscitation, and summarizes the relevant pediatric evidence.

A 60-year-old woman presented with polymorphic ventricular tachycardia secondary to hypokalemia, which necessitated dozens of DC cardioversions. She was not taking any other medication and denied any vomiting or diarrhea. Further investigation for hypokalemia suggested a hypermineralocorticoid state. Repeated inquiry prompted the patient to admit to taking herbal medicine containing licorice. She was treated with magnesium sulfate, potassium infusion, and intravenous lidocaine. A potassium-sparing diuretic was also prescribed. On the seventh day, the patient was discharged from the hospital with advice to discontinue taking herbal medicines containing licorice. She has been followed up at our outpatient clinic without further symptoms for 3 years. This case highlights the potential for cardiovascular complications associated with consumption of herbal medicines such as licorice. Clinicians should be aware that patients presenting to the emergency department with ventricular arrhythmia and uncertain hypokalemia should be questioned about licorice intake. Obtaining a detailed history from patients admitted to the hospital for electrical storm is essential.

OBJECTIVES: Ultrasound has an established role in the diagnostic pathway for children with suspected appendicitis. Relevant clinical information can influence the diagnostic probability and reporting of ultrasound findings. A Bayesian network (BN) is a directed acyclic graph (DAG) representing variables as nodes connected by directional arrows permitting visualisation of their relationships. This research developed a BN model with ultrasonographic and clinical variables to predict acute appendicitis in children. METHODS: A DAG was designed through a hybrid method based on expert opinion and a review of literature to define the model structure; and the discretisation and weighting of identified variables were calculated using principal components analysis, which also informed the conditional probability table of nodes. RESULTS: The acute appendicitis target node was designated as an outcome of interest influenced by four sub-models, including Ultrasound Index, Clinical History, Physical Assessment, and Diagnostic Tests. These sub-models included four sonographic, three blood-test, and six clinical variables. The BN was scenario tested and evaluated for face, predictive, and content validity. A lack of similar networks complicated concurrent and convergent validity evaluation. CONCLUSIONS: To our knowledge, this is the first BN model developed for the identification of acute appendicitis incorporating imaging variables. It has particular benefit for cases in which variables are missing because prior probabilities are built into corresponding nodes. It will be of use to clinicians involved in ultrasound examination of children with suspected appendicitis, as well as their treating clinicians. Prospective evaluation and development of an online tool will permit validation and refinement of the BN.
