RESUMEN

Lower back pain (LBP) is a frequent complaint, even among young people. The most common cause is attributed to slipped discs or vertebral fractures. Less common etiologies should also be considered when presenting with typical symptoms of severe backache. Here, we are presenting one such uncommon case. A 32-year-old man with a history of meningocele repair in neonates presented with severe backache, urinary retention, and constipation in an emergency. Initially, the patient was treated elsewhere, but symptoms persisted. A contrast-enhanced MRI done in the emergency revealed a rare sacral spinal epidural arteriovenous fistula (SEDAVF) with cord congestion. The patient was taken up for digital subtraction angiography, which confirmed the diagnosis, and was treated successfully with endovascular embolization. This case highlights the complex presentation of SEDAVF and the importance of prompt diagnosis and intervention.

RESUMEN

In Japan, there is a shortage of emergency medicine specialists, often leading non-specialists (physicians who treat conditions outside their area of specialty) to handle cases outside their expertise, which can cause challenges and necessitate specialist support. Starting from December 2023, the St. Marianna University Hospital, which has emergency medicine specialists, began offering overnight emergency outpatient support to Kawasaki Municipal Tama Hospital using the Teladoc HEALTH Mini Cart telemedicine device (Teladoc Health, Inc., CA, USA). The case involved a 44-year-old male with a history of peritonsillar abscess and incisional drainage presented with pharyngeal pain. The treating physician at the Kawasaki Municipal Tama Hospital and a neurologist (the supported physician) examined the patient at 9 PM. An enlarged right tonsil was noted, and a peritonsillar abscess was suspected, prompting a contrast-enhanced CT scan. The results confirmed a 1 cm right peritonsillar abscess. Faced with the decision to transfer the patient to a higher medical facility, the supported physician consulted with the support physician through a Teladoc HEALTH Mini Cart. The St. Marianna University Hospital's emergency physician (supporting physician) used the Teladoc HEALTH Mini Cart to assess the patient's overall condition, blood tests, and CT images and advise on antibiotic treatment. A visit to the ear, nose, and throat expert (ENT) the following day was considered sufficient. The supported physician received feedback that the use of the Teladoc HEALTH Mini Cart reduced the burden of nighttime transfers for otolaryngological conditions, which can take several hours. This finding suggests that remote medical support can affect Japan's emergency medical system.

RESUMEN

We present a case of a 58-year-old man who had asthma and developed necrotizing pneumonia (NP). The Computed Tomography (CT) scan of his chest showed cavitating consolidation with hydropneumothorax. Despite chest tube insertion and antibiotics, the patient did not improve. Therefore, surgical intervention was considered, and he underwent a right posterior-lateral thoracotomy, with middle lobe lobectomy, and decortication. As a result, the patient's condition started to improve, and he was discharged in good health.

RESUMEN

Objective: Despite depression being common in residents, there are no published studies on the prevalence and risk factors for depression in emergency medicine (EM) interns. Our objectives were to explore the prevalence of depression among EM interns and to identify risk factors for depression including sleep, work hours, rotation type, race, ethnicity, sex, and age. Methods: The Intern Health Study is a national longitudinal cohort study on intern mental health in all specialties. Secondary analysis was performed for EM interns only in this study. Data were collected from 2007 to 2021 and study participants completed a pre-intern year baseline survey and quarterly surveys throughout intern year, which included demographics and information on depressive symptoms, work hours, sleep, and rotation specifics. Depression severity was objectified using the Patient Health Questionnaire (PHQ9) with scores of 10 and higher meeting criteria for moderate to severe depression. Results: A total of 1123 EM interns completed all surveys. The prevalence of moderate to severe depression among EM interns before starting internship was 4.8%. At Months 3, 6, 9, and 12 of intern year, the prevalence of moderate to severe depression was 17.8%, 20.5%, 20.8%, and 18.8%, respectively. PHQ9 scores were significantly higher at Month 3 of intern year compared to pre-intern year, but there were no differences at subsequent time points during intern year (p < 0.001). Females were more likely to have PHQ9 scores of 10 or above at all time points (p < 0.001). Clinical rotation type had a significant effect on PHQ9 scores, with intensive care unit rotations having a significantly higher PHQ9 score than other rotations (p < 0.001). Pearson's correlation revealed significant weak positive correlations between work hours and PHQ9 at each time point (r = 0.195, 0.200, 0.202, 0.243) and significant weak negative correlations between sleep hours and time off with PHQ9 (-0.162, -0.223, -0.180, -0.178; all p < 0.001). Conclusions: Many EM interns experience moderate to severe depression. Female EM interns are more likely to be depressed than male interns. Numerous factors influence depression scores for interns, many of which are modifiable.

RESUMEN

Introduction Geriatric hip fractures present a difficult challenge in the emergency department (ED) to achieve adequate analgesia. Opioid-sparing ultrasound-guided fascia iliaca compartment blocks (UFIB) have been shown to be both safe and effective in treating pain from hip fractures. In this study, we investigated the teachability of UFIB to emergency medicine (EM) residents using simulation models and also assessed if UFIB training increases its utility in the ED. Methods We created a UFIB model to simulate the procedure in a controlled environment. Sixteen residents from Loma Linda Emergency Medicine Residency participated in a pre-workshop survey and hands-on UFIB workshop. Comfort level in performing UFIB and confidence level in needle finding skills during UFIB were analyzed, plotted, and represented graphically. Results Comfort level in performing UFIB increased by approximately 50% (p < 0.01). Success rates also increased by 460% (p<0.05) after the workshop. However, the UFIB continued to be underutilized as 44% of respondents expressed that there is a "lack of time" to perform UFIB during their shifts. Conclusion A single one-hour workshop increased comfort level in performing UFIB and helped residents successfully achieve better pain control in patients with hip fractures. However, residents continued to refrain from using UFIB because it is too time-consuming.

RESUMEN

This unique case depicts the first published report of a physician using point-of-care ultrasound to diagnose an esophageal stent migration. Discussed in this article are the sonographic findings that clinicians should be familiar with when evaluating patients with abdominal pain or chest pain who have a history of an esophageal stent. When coupled with a high index of suspicion, ultrasound can be one of the most portable, readily available, low-cost, and minimally invasive techniques for making a rapid diagnosis of esophageal stent migration.

RESUMEN

Conventional wisdom suggests that in almost every profession, the most experienced and educated employees are remunerated at a higher rate than the less experienced ones. For example, new-graduate hires most commonly start at the bottom of the pay scale. No profession could reflect the importance of experience and the need for mastery of skills more than emergency medicine (EM), where a split-second decision could mean the difference between life and death. In Canada, however, EM physicians are remunerated as per a common pay scale that does not consider the length of their education, training, or years of practice. Such an unfair experience-remuneration mismatch (E-R mismatch) could lead to job dissatisfaction, burnout, and switching to other specialties. Given the current EM physician shortage in Canada, the E-R mismatch among such physicians could negatively impact patient care and the health system as a whole and prolong the already long wait times. The aim of this editorial is to shed light on this flaw in the Canadian healthcare system and lead to change toward a fair pay system. The creation of a professional and experience-based hierarchy among Canadian EM physicians should be considered a matter of urgency for those developing health-related legislation.

RESUMEN

STUDY OBJECTIVE: Cardiac tamponade is an impending calamitous disorder that emergency physicians need to consider and diagnose rapidly. A pericardial effusion with right atrial systolic collapse (earliest sign) or right ventricular diastolic collapse (most specific sign) and a plethoric inferior vena cava are indicators of cardiac tamponade physiology and may be identified with point-of-care ultrasonography (POCUS). The goal of this study is to assess the agreement among emergency physicians with varying levels of sonographic training and expertise in interpreting echocardiographic signs of cardiac tamponade in adult patients.  Methods: Emergency physicians at different levels of training as sonographers were surveyed at didactic conferences at three major academic medical centers in northern New Jersey. Two cardiologists were also included in the study for comparison. Survey respondents were shown 15, 20-second video clips of patients who had presented to the emergency department (ED) with or without significant pericardial effusions and were asked to rate whether tamponade physiology was present or not. Data were collected anonymously on Google Forms (Google LLC, Mountain View, CA) and included self-reported levels of POCUS expertise and level of training. Data were analyzed using Fleiss' kappa (k). All patients had an echocardiogram performed by the department of cardiology within 24 hours of the POCUS, and the results are presented in the paper.  Results: There were 97 participant raters, including attendings, fellows, and resident physicians specializing in adult emergency medicine and two cardiologists. There was a fair degree of inter-rater agreement among all participants in interpreting whether tamponade physiology was present or not. This low level of agreement persisted across self-reported training levels and self-reported POCUS expertise, even at the expert level in both emergency medicine and cardiology specialties. CONCLUSION: According to the results of our study, there appears to be a low level of agreement in the interpretation of cardiac tamponade in adult patients. The lack of agreement persisted across specialties, self-reported training levels, and self-reported ultrasonographic expertise. This low level of agreement seen among both specialists indicates that emergency physicians are not limited in their ability to determine cardiac tamponade on POCUS. This highlights the technical nature of POCUS clips and strengthens the importance of physical exam findings when diagnosing cardiac tamponade in emergency department patients. Further research utilizing POCUS for the diagnosis of tamponade is warranted.

RESUMEN

Introduction The challenges of delivering cardiac arrest (CA) courses in rural and remote (R&R) locations worldwide have been further exacerbated by the COVID-19 pandemic. However, it is important to note that this problem has always existed. The implementation of social distancing measures to combat the pandemic has had a significant impact on healthcare and medical education, particularly in relation to the training of students, laypeople (LP), and healthcare professionals (HCPs) in CA care. The combination of pandemic restrictions and pre-existing difficulties faced in R&R locations and large cities has disrupted the provision of comprehensive medical education. The suspension of basic life support and defibrillation (BLSD) courses during the pandemic may have negatively affected pre-hospital care for CA. However, it is essential to acknowledge that challenges in delivering these courses in R&R areas predate the pandemic. Materials and methods A 2021 epidemiological study in the Brazilian Amazon identified CA as the primary cause of death, followed by COVID-19. This highlights the importance of providing BLSD courses and training to emergency medical service (EMS) personnel in R&R locations. Even during a pandemic. Researchers from Ontario Tech University and Memorial University School of Medicine developed a drone with a simulation scenario to train HCPs in automated external defibrillators (AED) operation and guide LP in safe use through BLSD protocols. A literature review showed that different training methods yielded similar outcomes. Based on these findings, the evidence-development-validation-consensus (EDVC) hybrid approach was used to develop and validate an online training program using a learning management system (LMS) as a model. Results Teaching HCPs and LP in R&R locations, such as northern Canada and the Brazilian Amazon, presents challenges due to limited resources and internet access. One potential solution lies in the utilization of remote online LMS that facilitate the administration, documentation, tracking, reporting, automation, and delivery of educational courses and training programs. The literature review indicated that mixed training approaches, including face-to-face, online, and hybrid formats, produced similar outcomes in learning assessment, self-confidence, performance, skills, and knowledge acquisition. These findings support the viability of using LMS as a model to develop and validate a course where drones deliver AEDs and provide training to HCPs and LP in R&R locations. A comprehensive training program should encompass cognitive, affective, and psychomotor learning domains, addressing various skills and knowledge aspects. Conclusion This research study develops and validates LMS teaching methods to support a training program for HCPs and LP in using AEDs delivered by drones. The program combines design-based research and consensus development methods, such as design thinking and think-aloud observations. Drones are used to provide AEDs and develop simulation scenarios for training in R&R locations. The hybrid approach ensures a valid and evidence-based training program. The study presents the EDVC approach used to enhance the maxSIMdrone training program, enabling effective out-of-hospital CA care. The program incorporates participant feedback and improves knowledge and techniques in AED use. It has the potential to improve patient outcomes in resource-limited R&R locations.

RESUMEN

Objective: Burnout negatively affects the wellness and performance of emergency physicians (EPs). This study aimed to clarify the actual prevalence of burnout and its associated factors among Japanese EPs. Methods: We conducted a cross-sectional questionnaire study of selected 27 Japanese emergency departments (EDs). We examined the Maslach Burnout Inventory-Human Services Survey score and its associations with ED-level- and EP-level factors in a multivariable analysis. Results: A total of 267 EPs (81.9%) completed survey. Of these, 43 EPs (16.1%) scored severe emotional exhaustion (EE), 53 (19.8%) scored severe depersonalization (DP), and 179 (67.0%) scored severe personal accomplishment (PA), and 24 (8.9%) scored severely in all three domains. In our multivariable analysis, emergency medical service centers were associated with severe PA scores (odds ratio [OR], 10.56; 95% confidence interval [CI], 1.78-62.66; p = 0.009). A 3 to 6 hour-sleep period was associated with severe EE scores (OR, 2.04; 95% CI, 1.04-3.98; p = 0.036), and EPs in their 20s were associated with severe DP scores (OR, 7.37; 95% CI, 1.41-38.38; p = 0.018). Conclusion: Our results suggest that 8.9% of Japanese EPs are in higher degrees of burnout. In particular, Japanese EPs scored more severely on PA. To avoid burnout in Japanese EPs, it is important to improve the working environment by ensuring more than 6 h of sleep, providing more support for young EPs, and taking effective action to combat low EP self-esteem.

RESUMEN

Background Burn is a skin injury that results in the death of the impacted cells. Burn injuries are frequently unintentional and very avoidable. With proper management, the outcome is improved, and the need for surgical intervention is reduced. This article discusses healthcare providers' knowledge and practice of burn first aid and management to highlight the need for the enhanced practice of burn management and first-aid skills. Objective This study aims to assess the knowledge and practice of burn injuries management among healthcare workers in different specialties in Hail city. Methods  A cross-sectional study was conducted via an interviewer-administrated face-to-face questionnaire and video recording of a simulated case of burn injury collected from our skill lab at Hail University and evaluated by a board-certified plastic surgeon. Result The study analyzed 119 physicians (mean age = 36.3 years, SD = 6.7) managing burn cases. Of these, 59.7% were male, and 40.3% were female. The mean evaluation score was 7.71 (SD = 2.84). None of the factors studied, including gender (p = 0.353), age (p = 0.970), education level (p = 0.127), specialty (p = 0.871), professional experience (p = 0.118), working sector (p = 0.178), nationality (p = 0.742), or participation in burn management course (p = 0.131), had a significant effect on burn management skills of physicians. However, some groups had higher mean evaluation scores than others. Further research is needed to explore potential reasons for the observed differences in mean evaluation scores among different groups of physicians. Conclusion We discovered that most physicians were found to have poor practical knowledge of proper burn management, and most of them had not engaged in a burn first aid training, therefore more courses targeting physicians who may meet burn patients are required.

RESUMEN

Emergency Medicine core clinical privileges include administration of thrombolytic therapy for myocardial infarction and stroke. However, emergency medicine providers have created their own paradigm to rely on neurology specialty consultation to treat acute stroke patients. A 2013 study supported by the American Academy of Neurology showed an 11% shortage of neurologists at that time and projected a 19% shortage by 2025. The lack of neurologists is a worldwide problem. To help ease the shortage, teleneurology and telestroke care has been implemented by neurologists, most notably for acute ischemic stroke (AIS) patients. We present a model in which an Emergency Medicine (EM) Stroke Champion (SC); an EM physician within our Neurologic Emergency Department, directs care for acute stroke patients at our comprehensive hub and primary stroke center spoke hospitals. The SCs independently treat patients with fibrinolytic therapy and provide teleneurology to fellow emergency physicians caring for acute stroke patients at spoke hospitals. Over nineteen months the SCs received 457 phone calls for patients meeting stroke alert criteria. Sixteen patients were deemed eligible for IV alteplase with one hemorrhagic conversion (6.25%). Sixty-four patients required transfer, and this was facilitated by the SCs. The concept of emergency physician SCs providing teleneurology consultation to other fellow emergency physicians was found to be feasible and safe. This model has the potential to be generalized not to just stroke champions, but to all emergency physicians to feel both confident and comfortable treating acute stroke patients.

RESUMEN

OBJECTIVES: Fatigue is a state of physical and mental exhaustion in which people feel exhausted or drained of energy. Shift workers are highly vulnerable to fatigue, and this is especially true of emergency physicians (EPs). Shift scheduling (shift hours, frequency/length of breaks, time of shift, and number of hours off between shifts) can affect levels of fatigue in EPs. When EPs are fatigued, they experience decrements in cognition, resulting in an increased risk of errors. This study assessed the state of fatigue in EPs in the emergency department of a large, urban hospital using objective measures (sleep metrics and shift scheduling) over multiple months. METHODS: Seventeen EPs, nine females, wore wrist-activity monitors called ReadiBands for 2 months. The ReadiBand is an objective actigraphy measure that communicates with a smartphone application to quantify sleep metrics and predict future fatigue. RESULTS: Throughout the 3083 on-shift hours of data, analyses revealed that EPs have poor sleep quality (mean ± SD 7.71 ± 1.84/10) and sleep quantity (mean ± SD 6.77 ± 1.66 h), with sleep efficiency within "normal" ranges (mean ± SD 87.26 ± 9.00). Participants spent 725 h (23.52%) on shifts with fatigue scores indicative of significant impairment (equivalent to BAC of .08%). In addition, results indicated that shift type (day, evening, night) was significantly associated with fatigue score, where night shifts were associated with higher fatigue scores. CONCLUSIONS: Fatigue is an issue for many EPs. The present study addressed the percentage of time EPs are in a fatigued state when on shift over an extended duration of time. More research is needed to examine system-level interventions for reducing fatigue in EPs.

RESUMEN

BACKGROUND: Chest radiographs are the most basic and readily available imaging modality for visualizing the lungs and are potentially useful for describing the disease severity in patients showing respiratory symptoms in COVID-19 patients. The early diagnosis of COVID-19 features on radiography helps in triaging and starting treatment. MATERIAL AND METHODS: Our study consisted of 145 radiographs, and these were reported by two radiologists, two emergency physicians and one intern working in the Emergency department. The scores given by them were correlated. A targeted short lecture for the scoring was imparted and after a sufficient latent period the scoring of chest radiographs was done again, and the scores correlated and compared. RESULTS: We observed agreement between radiologists with emergency medicine physicians was "none to slight" to "fair," before the dedicated online teaching course. Following the meeting, there was an increase in interobserver agreement in-between radiologists and between radiologists and emergency medicine physicians. CONCLUSIONS: We propose a focused online meeting, targeted at explaining radiological features of a specific pathology, in a pandemic situation like COVID, to our clinical counterparts in the emergency medicine department can help in increasing their interpretation skills. This can directly benefit triaging, admission/discharge and monitoring of the status of patients, in intensive care units and emergency medicine. This also helps in allaying the anxiety, while waiting for a final report from the Radiologist.

RESUMEN

Since its outbreak, it's been well-documented that coronavirus disease 2019 (COVID-19) can present with wide variety of neurological manifestations in absence of the usual respiratory symptoms. We report one such severe neurological manifestation of SARS-CoV-2 infection. To our knowledge, this is the first reported case of COVID-19 encephalopathy with CSF and MRI findings in the United Arab Emirates. We present a case of a 52-year-old female who presented with complaints of altered mentation, anosmia, headache, dizziness, weakness, lethargy, and vomiting. While in the emergency department she developed two generalized tonic-clonic seizure episodes, a more pronounced delirium, and tachypnea which required intubation. She was then admitted to the intensive care unit (ICU). She was COVID-19 positive and subsequent MRI revealed encephalopathy. She was discharged from ICU and was under long-term care at the time of case documentation.

RESUMEN

Herein, we describe an agitated geriatric patient who suffered an adverse outcome due to treatment for agitation in an emergency setting. This led to the prompt review of the current literature on best-practice medication to use in this population. After careful review, the authors recommend olanzapine as the first-line medication for agitation due to its lower risk-averse effect profile when compared to other medications used for this patient population.

RESUMEN

Purpose: To assess the views of emergency medicine physicians (EMPs) on the practice of providing unnecessary medical management in the emergency department. Methods: All EMPs in Saudi Arabia were approached to participate in this cross-sectional study. A self-administered online survey that collected the participants' demographic information and opinions regarding the unnecessary management provided by EMPs in Saudi Arabia was conducted between December 2020 and February 2021. SPSS 22.0 was used to analyze the data. Results: A total of 181 EMPs returned the questionnaire. More than 80% of the participants believed that EMPs order unnecessary tests or procedures at least a few times per week. The major reasons for ordering unnecessary medical tests or procedures were "concern about malpractice issues" (60.8%), "not having enough time with a patient for meaningful discussion" (47%), and "just to be safe" (46.4%). More than 55% of the respondents also believed that EMPs are in the best position to address the problem of unnecessary testing. Conclusion: Most of the EMPs who participated in this study recognized that ordering unnecessary tests is a serious problem that happens on a daily basis. Many factors and reasons were described by the participants, and multiple possible solutions were suggested to help overcome the issue. Evaluating physicians' perspectives on the issue is a key step in addressing the problem and implementing appropriate interventions.

RESUMEN

Objective Although the urban emergency workforce is well studied, rural departments are less understood. This study seeks to further define the landscape of rural healthcare and expand on previous studies of the West Virginia (WV) workforce. Methods During the second quarter of 2019, surveys were sent via email to medical directors' professional IDs as anonymous survey links. Hard copies were also sent to directors at their hospital addresses. Responses were aggregated with hospitals stratified based on annual census and rural classification. Data was interpreted through descriptive analysis. Results Surveys were sent to 53 departments with a 55% response rate. Of the responding hospitals, 15 of 29 were identified as rural. The average state-wide annual hospital census was 29,500 visits with board-certified emergency medicine (EM)-trained physicians covering 67% of shifts. Rural departments have a smaller census and less specialized coverage. Full-time physicians are found to have the strongest ties to WV, with 65% attending medical school, residency, or growing up in the state. Conclusion Board-certified EM-trained physicians provide some level of coverage in most emergency departments in WV but remain underrepresented in rural locations. This specialized coverage has increased by 20% in the last 15 years. Additionally, a majority of hospitals have access to basic consulting services (surgery and primary care); however, other specialists are rare in rural WV.

RESUMEN

Background Point-of-care ultrasound (PoCUS) is frequently utilized in emergency medicine (EM), with an extended-focused assessment with sonography in trauma (e-FAST) being the most widely used PoCUS modality. This modality is not only time- and cost-efficient, but it is highly accurate in the diagnosis and management of surgical patients in the emergency department, as well as being highly predictive of patient outcomes. Targeted training is essential to ensure a learner's confidence in image acquisition, interpretation, and translation of knowledge to making clinical decisions. High-fidelity simulation offers a uniquely safe and "mistake-forgiving" environment to teach and train medical professionals. The present study evaluated the effectiveness of a high-fidelity simulator to train EM physicians in e-FAST at a tertiary care teaching hospital in a lower-middle-income country. Methods This quasi-experimental study was performed at a state-of-the-art simulation center of a multidisciplinary university hospital in Karachi, Pakistan. Subjects were included if they were EM physicians who volunteered to participate and were available for the entire training and testing period. The educational intervention included lectures and hands-on practice on a high-fidelity simulator (SonoSim, Santa Monica, CA). Knowledge and image interpretation on e-FAST were evaluated using a questionnaire, administered before and after the training course. Each participant's ability to acquire and interpret satisfactory images was assessed by experienced EM physicians and recorded. Participants were also administered a needs assessment survey and a course evaluation. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (Armonk, NY: IBM Corp.). All the tests were two-sided, and p-values ≤0.05 were considered significant. Baseline characteristics and outcome variables were recorded and compared by Wilcoxon signed-rank tests. Results A total of 31 EM physicians, 12 (38.7%) men and 19 (61.3%) women, were enrolled in the study, with 24 (77.3%) having one to three years of EM experience. Mean and percentage group performance improved from 6 and 40% before the intervention to 14.5 and 96.6% after the intervention (Z=4.867, p≤0.05). Most improvement in image acquisition on high-fidelity simulation was observed in the upper right quadrant of the suprapubic window (29/31; 93.5%), followed by the upper left quadrant (27/31; 87%) and the subxiphoid window (21/31; 67%). All 31 participants reported improvements in comfort and confidence level with PoCUS after attending the workshop. Conclusions EM physicians who attended a brief workshop incorporating simulation demonstrated improvements in knowledge and image acquisition skills in all domains tested. High-fidelity simulation training is an effective modality for training EM physicians in e-FAST.

RESUMEN

Objectives Airway ultrasound is now possible in the prehospital setting due to advances in ultrasound equipment portability. We questioned how well prehospital providers without prior experience could determine both esophageal and tracheal placement of an endotracheal tube in cadavers after a brief training course in ultrasound.  Methods This educational prospective study at the Simulation Center in Mayo Clinic Jacksonville Florida enrolled 50 prehospital providers. Demographic and practice background information was obtained through surveys. Each participant performed a baseline ultrasound to determine endotracheal tube placement in a cadaver that was randomly assigned to an esophageal or tracheal intubation. Participants then repeated the randomized testing after a 15-minute tutorial. Before and after overall accuracy as well as proportions of correct identification of esophageal and tracheal intubations were determined and compared using standard binomial proportion and McNemar's tests. Results  None of the participants had prior experience of performing airway ultrasound. Baseline group scores were 60% (CI 45%-74%) for overall accuracy (n=50), 55% (CI 32%-76%) for correct identification of an esophageal intubation, and 64% (CI 44%-81%) for correct tracheal detection. Baseline scores were not significantly different from standard binomial distributions. Post-test scores were 82% (CI 69%-91%) for overall accuracy, 96% (CI 80%-100%) for esophageal intubation detection, and 66.7% (CI 45%-84%) for tracheal intubation detection, with corresponding binomial p-values of <0.001, <0.001, and 0.15. P-values for McNemar's paired test for combined overall accuracy, correct esophageal detection, and correct tracheal detection were 0.04, 0.02, and 0.62, respectively. Conclusions Prehospital participants without prior ultrasound experience demonstrated significant gains in airway ultrasound proficiency after a limited introductory course. Post-training score increases were largely due to a notable increase in correct esophageal intubation detection rates. Learners did not make significant progress in correctly identifying a tracheal intubation. Airway ultrasound educational design may benefit from added emphasis on the potentially more difficult to recognize tracheal intubation view.
