BACKGROUND: Our investigation aimed to determine how the diverse backgrounds and medical specialties of emergency physicians (Eps) influence the accuracy of diagnoses and the subsequent treatment pathways for patients presenting preclinically with MI symptoms. By scrutinizing the relationships between EPs\' specialties and their approaches to patient care, we aimed to unveil potential variances in diagnostic accuracy and treatment choices.
METHODS: In this retrospective, monocenter cohort study, we leveraged machine learning techniques to analyze a comprehensive dataset of 2328 patients with suspected MI, encompassing preclinical diagnoses, electrocardiogram (ECG) interpretations, and subsequent treatment strategies by attending EPs.
RESULTS: We demonstrated that diagnosis and treatment patterns of different specialties were distinct enough, that machine learning (ML) was able to differentiate between specialties (maximum area under the receiver operating characteristic = 0.80 for general medicine and 0.80 for surgery). In our study, internist demonstrated the highest accuracy for preclinical identification of STEMI (0.96) whereas surgeons showed the highest accuracy for identifying NSTEMI. Our findings highlight significant correlations between EP specialties and the accuracy of both preclinical diagnoses and subsequent treatment pathways for patients with suspected MI.
CONCLUSIONS: Our results offer valuable insights into how the diverse backgrounds and specialties of EPs can influence the optimization of patient care in emergency settings. Understanding these patterns can help in the development of tailored training programs and protocols to enhance diagnostic accuracy and treatment efficacy in emergency cardiac care, ultimately optimizing patient treatment and improving outcomes.

UNASSIGNED: A considerable percentage of daily emergency calls are for nursing home residents. With the ageing of the overall European population, an increase in emergency calls and interventions in nursing homes (NH) is to be expected. A proportion of these interventions and hospital transfers may be preventable and could be considered as inappropriate by prehospital emergency medical personnel. The study aimed to understand Belgian emergency physicians\' and emergency nurses\' perspectives on emergency calls and interventions in NHs and investigate factors contributing to their perception of inappropriateness.
UNASSIGNED: An exploratory non-interventional prospective study was conducted in Belgium among emergency physicians and emergency nurses, currently working in prehospital emergency medicine. Electronic questionnaires were sent out in September, October and November 2023. Descriptive statistics were used to analyze the overall results, as well as to compare the answers between emergency physicians and emergency nurses about certain topics.
UNASSIGNED: A total of 114 emergency physicians and 78 nurses responded to the survey. The mean age was 38 years with a mean working experience of 10 years in prehospital healthcare. Nursing home staff were perceived as understaffed and lacking in competence, with an impact on patient care especially during nights and weekends. General practitioners were perceived as insufficiently involved in the patient\'s care, as well as often unavailable in times of need, leading to activation of Emergency Medical Services (EMS) and transfers of nursing home residents to the Emergency Department (ED). Advance directives were almost never available at EMS interventions and transfers were often not in accordance with the patient\'s wishes. Palliative care and pain treatment were perceived as insufficient. Emergency physicians and nurses felt mostly disappointed and frustrated. Additionally, differences in perception were noted between emergency physicians and nurses regarding certain topics. Emergency nurses were more convinced that the nursing home physician should be available 24/7 and that transfers could be avoided if nursing home staff had more authority regarding medical interventions. Emergency nurses were also more under the impression that pain management was inadequate, and emergency physicians were more afraid of the medical implications of doing too little during interventions than emergency nurses. Suggestions to reduce the number of EMS interventions were more general practitioner involvement (82%), better nursing home staff education/competences (77%), more nursing home staff (67%), mobile palliative care support teams (65%) and mobile geriatric nursing intervention teams (52%).
UNASSIGNED: EMS interventions in nursing homes were almost never seen as necessary or indicated by emergency physicians and nurses, with the appropriate EMS level almost never being activated. The following key issues were found: shortages in numbers and competence of nursing home staff, insufficient primary care due to the unavailability of the general practitioner as well as a lack of involvement in patient care, and an absence of readily available advance directives. General practitioners should be more involved in the decision to call the Emergency Medical Services (EMS) and to transfer nursing home residents to the Emergency Department. Healthcare workers should strive for vigilance regarding the patients\' wishes. The emotional burden of deciding on an avoidable hospital admission of nursing home residents, perhaps out of fear for medico-legal consequences if doing too little, leaves the emergency physicians and nurses frustrated and disappointed. Improvements in nursing home staffing, more acute and chronic general practitioner consultations, and mobile geriatric and palliative care support teams are potential solutions. Further research should focus on the structural improvement of the above-mentioned shortcomings.

BACKGROUND: Artificial intelligence, particularly chatbot systems, is becoming an instrumental tool in health care, aiding clinical decision-making and patient engagement.
OBJECTIVE: This study aims to analyze the performance of ChatGPT-3.5 and ChatGPT-4 in addressing complex clinical and ethical dilemmas, and to illustrate their potential role in health care decision-making while comparing seniors\' and residents\' ratings, and specific question types.
METHODS: A total of 4 specialized physicians formulated 176 real-world clinical questions. A total of 8 senior physicians and residents assessed responses from GPT-3.5 and GPT-4 on a 1-5 scale across 5 categories: accuracy, relevance, clarity, utility, and comprehensiveness. Evaluations were conducted within internal medicine, emergency medicine, and ethics. Comparisons were made globally, between seniors and residents, and across classifications.
RESULTS: Both GPT models received high mean scores (4.4, SD 0.8 for GPT-4 and 4.1, SD 1.0 for GPT-3.5). GPT-4 outperformed GPT-3.5 across all rating dimensions, with seniors consistently rating responses higher than residents for both models. Specifically, seniors rated GPT-4 as more beneficial and complete (mean 4.6 vs 4.0 and 4.6 vs 4.1, respectively; P<.001), and GPT-3.5 similarly (mean 4.1 vs 3.7 and 3.9 vs 3.5, respectively; P<.001). Ethical queries received the highest ratings for both models, with mean scores reflecting consistency across accuracy and completeness criteria. Distinctions among question types were significant, particularly for the GPT-4 mean scores in completeness across emergency, internal, and ethical questions (4.2, SD 1.0; 4.3, SD 0.8; and 4.5, SD 0.7, respectively; P<.001), and for GPT-3.5\'s accuracy, beneficial, and completeness dimensions.
CONCLUSIONS: ChatGPT\'s potential to assist physicians with medical issues is promising, with prospects to enhance diagnostics, treatments, and ethics. While integration into clinical workflows may be valuable, it must complement, not replace, human expertise. Continued research is essential to ensure safe and effective implementation in clinical environments.

BACKGROUND: Academic emergency medicine (EM) is foundational to the EM specialty through the development of new knowledge and clinical training of resident physicians. Despite recent increased attention to the future of the EM workforce, no evaluations have specifically characterized the U.S. academic EM workforce. We sought to estimate the national proportion of emergency physicians (EPs) identified as academic and the proportion of emergency department (ED) visits that take place at academic sites.
METHODS: We performed a cross-sectional analysis of EPs and EDs using data from the American Hospital Association, the Centers for Medicare & Medicaid Services, and Doximity\'s Residency Navigator. EPs were identified as \"academic\" if they were affiliated with at least one facility determined to be academic, defined as EDs officially designated by the Accreditation Council for Graduate Medical Education (ACGME) as clinical training sites at accredited EM residency programs. Our primary outcomes were to estimate the national proportion of EPs identified as academic and the proportion of ED visits performed at academic sites.
RESULTS: Our analytic sample included 26,937 EPs practicing clinically across 4920 EDs and providing care during 130,471,386 ED visits. Among EPs, 11,720 (43.5%) were identified as academic, and among EDs, 635 (12.9%) were identified as academic sites, including 585 adult/general sites, 45 pediatric-specific sites, and 10 sites affiliated with the Department of Veterans Affairs. In 2021, academic EDs provided care for 42,794,106 ED visits or 32.8% of all ED visits nationally.
CONCLUSIONS: Approximately four in 10 EPs practice in at least one clinical training site affiliated with an ACGME-accredited EM residency program, and approximately one in three ED visits nationally occur in these academic EDs. We encourage further work using alternative definitions of an academic EPs and EDs, along with longitudinal research to identify trends in the workforce\'s composition.

UNASSIGNED: Cauda equina syndrome (CES) is a consequence of a variety of etiologies. CES is most commonly due to compression of the thecal sac and nerve roots by a massive disc herniation. However, it rarely presents secondary to aortic occlusion. Aortoiliac occlusive disorder is usually associated with chronic claudication, erectile dysfunction, and diminished lower limb pulses. Acute aortic occlusion, however, is associated with serious complications such as spinal cord infarction and ischemia. It is also associated with a high risk of morbidity and mortality. Moreover, it poses a diagnostic challenge and may be overlooked. This report emphasizes the importance of considering vascular etiology as a differential diagnosis for CES.
UNASSIGNED: This case report describes a unique case of aortic occlusion mimicking CES in a 56-year-old female patient.
UNASSIGNED: For patients presenting with cauda equina symptomatology, it is critical to consider vascular etiology, especially for those with cardiovascular risk factors. Spine surgeons and emergency physicians should maintain a high index of suspicion for vascular etiologies and consider appropriate imaging studies to promote early diagnosis and intervention to prevent subsequent neurological and life-threatening consequences.

BACKGROUND: Financial relationships between physicians and the health care industry are common in the United States. Yet, there are limited data on payments to emergency physicians since the 2014 launch of the Open Payments Database.
OBJECTIVE: To analyze the trends and characteristics of industry payments to U.S. emergency physicians from 2014 to 2022.
METHODS: This retrospective study used the Open Payments Database to examine all general and research payments to all active emergency physicians. Descriptive statistics and generalized estimating equations were employed.
RESULTS: Between 2014 and 2022, 50.1% (33,021) of emergency physicians received $640.1 million in payments. Of these, 50.1% received general payments, and 1.2% received research payments. General payments constituted 18.7% ($119.7 million) of the overall industry payments. Median general and research payments were $149 ($49-$401) and $72,083 ($13,903-$370,142), respectively. Compared with other specialties, fewer emergency physicians received general payments, and the amounts were lower. The top 1% of emergency physicians received 80.5% of the general payments. No significant trends in payment amounts were observed from 2014 to 2019, but there was a significant decrease in both types of payments in 2020 due to the COVID-19 pandemic.
CONCLUSIONS: The majority of emergency physicians received payments from the health care industry, although these payments were typically minimal compared with other specialties. Payment trends remained consistent from 2014 to 2019, with a notable decrease in 2020 due to the pandemic.

Background The only cure for end-organ failure is transplantation. Unfortunately, there are fewer organ donors than patients. Currently, the majority of organ donations come from live or brain-dead donors. In order to expand the pool of potential organ donors, the emergency department should be utilized effectively. Objectives The primary goal of this research is to determine emergency physicians\' knowledge, awareness, and attitude about organ donation. Methodology A cross-sectional study was conducted through different hospitals in Saudi Arabia. It includes 106 physicians in the adult emergency departments. Results The majority (84.9%) of the participants never reported any case in the emergency department as a potential case for organ donation. In addition, 54.8% of the participants report having little to no knowledge of the ethical issues of organ donation. Furthermore, 66.1% of respondents claim to have little to no knowledge of the goals and duties of the SCOT (Saudi Center for Organ Transplantation). It was interesting to see that 96.2% of the participants reported that their organizations do not have any policies or procedures in place regarding organ donations. Regarding education, 99 (93.4%) physicians did not participate in any organ donation course, training, or teaching program about organ donation. At the same time, 67 (63.2%) physicians concurred that participation in a training program is essential. Moreover, 68 (64.2%) physicians believed that organ donation should be a part of every end-of-life case. In order to improve the donation process in the emergency department, 88 (83%) physicians would want a well-established program with defined policies and procedures. Conclusion According to our findings, the emergency physician has inadequate expertise and information on organ donation rules and procedures, which has resulted in a missed opportunity to recruit more potential donors. We recommend instituting clear policy and procedures and educating the physicians and all emergency medicine staff to have better outcome.

BACKGROUND: Physiological changes associated with ageing could negatively impact the crisis resource management skills of acute care physicians. This study was designed to determine whether physician age impacts crisis resource management skills, and crisis resource management skills learning and retention using full-body manikin simulation training in acute care physicians.
METHODS: Acute care physicians at two Canadian universities participated in three 8-min simulated crisis (pulseless electrical activity) scenarios. An initial crisis scenario (pre-test) was followed by debriefing with a trained facilitator and a second crisis scenario (immediate post-test). Participants returned for a third crisis scenario 3-6 months later (retention post-test).
RESULTS: For the 48 participants included in the final analysis, age negatively correlated with baseline Global Rating Scale (GRS; r=-0.30, P<0.05) and technical checklist scores (r=-0.44, P<0.01). However, only years in practice and prior simulation experience, but not age, were significant in a subsequent stepwise regression analysis. Learning from simulation-based education was shown with a mean difference in scores from pre-test to immediate post-test of 2.28 for GRS score (P<0.001) and 1.69 for technical checklist correct score (P<0.001); learning was retained for 3-6 months. Only prior simulation experience was significantly correlated with a decreased change in learning (r=-0.30, P<0.05).
CONCLUSIONS: A reduced amount of prior simulation training and increased years in practice, but not age on its own, were significant predictors of low baseline crisis resource management performance. Simulation-based education leads to crisis resource management learning that is well retained for 3-6 months, regardless of age or years in practice.

An updated overview of ultrasound (US) for diagnosis of acute cholecystitis (AC) remains lacking. This systematic review was conducted to evaluate the diagnostic performance of US for AC.
A systematic review was conducted following PRISMA guidelines. We meticulously screened articles from MEDLINE, Embase, and the Cochrane Library, spanning from inception to August 2023. We employed the search strategy combining the keywords \"bedside US\", \"emergency US\" or \"point-of-care US\" with \"AC\". Two reviewers independently screened the titles and abstracts of the retrieved articles to identify suitable studies. The inclusion criteria encompassed articles investigating the diagnostic performance of US for AC. Data regarding diagnostic performance, sonographers, and sonographic findings including the presence of gallstone, gallbladder (GB) wall thickness, peri-GB fluid, or sonographic Murphy sign were extracted, and a meta-analysis was executed. Case reports, editorials, and review articles were excluded, as well as studies focused on acalculous cholecystitis. The study quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool.
Forty studies with 8,652 patients were included. The majority of studies had a low risk of bias and applicability concerns. US had a pooled sensitivity of 71% (95% CI, 69-72%), a specificity of 85% (95% CI, 84-86%), and an accuracy of 0.83 (95% CI, 0.82-0.83) for the diagnosis of AC. The pooled sensitivity and specificity were 71% (95% CI, 67-74%) and 92% (95% CI, 90-93%) performed by emergency physicians (EPs), 79% (95% CI, 71-85%) and 76% (95% CI, 69-81%) performed by surgeons, and 68% (95% CI 66-71%) and 87% (95% CI, 86-88%) performed by radiologists, respectively. There were no statistically significant differences among the three groups.
US is a good imaging modality for the diagnosis of AC. EP-performed US has a similar diagnostic performance to radiologist-performed US. Further investigations would be needed to investigate the impact of US on expediting the management process and improving patient-centered outcomes.
