RESUMO
INTRODUCTION: Point-of-care ultrasound (US) is used in clinical practice across many specialties. Ultrasound (US) curricula for medical students are increasingly common. Optimal timing, structure, and effect of ultrasound education during medical school remains poorly understood. This study aims to retrospectively determine the association between participation in a preclinical, longitudinal US curriculum and medical student academic performance. METHODS: All first-year medical students at a medical school in the Midwest region of the United States were offered a voluntary longitudinal US curriculum. Participants were selected by random lottery. The curriculum consisted of five three-hour hands on-sessions with matching asynchronous content covering anatomy and pathologic findings. Content was paired with organ system blocks in the standard first year curriculum at our medical school. Exam scores between the participating and non-participating students were compared to evaluate the objective impact of US education on performance in an existing curriculum. We hypothesized that there would be an association between participation in the curriculum and improved medical student performance. Secondary outcomes included shelf exam scores for the surgery, internal medicine, neurology clerkships and USMLE Step 1. A multivariable linear regression model was used to evaluate the association of US curriculum participation with student performance. Scores were adjusted for age, gender, MCAT percentile, and science or engineering degree. RESULTS: 76 of 178 students applied to participate in the curriculum, of which 51 were accepted. US curriculum students were compared to non-participating students (n = 127) from the same class. The US curriculum students performed better in cardiovascular anatomy (mean score 92.1 vs. 88.7, p = 0.048 after adjustment for multiple comparisons). There were no significant differences in cumulative cardiovascular exam scores, or in anatomy and cumulative exam scores for the gastroenterology and neurology blocks. The effect of US curriculum participation on cardiovascular anatomy scores was estimated to be an improvement of 3.48 points (95% CI 0.78-6.18). No significant differences were observed for USMLE Step 1 or clerkship shelf exams. There were no significant differences in either preclinical, clerkship or Step 1 score for the 25 students who applied and were not accepted and the 102 who did not apply. CONCLUSIONS: Participation in a preclinical longitudinal US curriculum was associated with improved exam performance in cardiovascular anatomy but not examination of other cardiovascular system concepts. Neither anatomy or comprehensive exam scores for neurology and gastrointestinal organ system blocks were improved.

BACKGROUND: Sepsis is a high mortality condition characterized by multi-organ dysfunction. Sepsis-induced cardiomyopathy (SIC) refers to cardiac dysfunction in sepsis. OBJECTIVES: Our goal was to determine whether SIC can be detected in the emergency department (ED) using focused cardiac ultrasound (FCU). METHODS: A retrospective analysis of adults presenting to a single ED with sepsis over a 21-month period was performed. Patients were included if they met clinical sepsis criteria, received an FCU by an emergency physician in the ED, and a baseline echocardiogram performed in the previous 12 months. SIC was defined as a significant decrease in estimated left ventricular ejection fraction (LVEF) by FCU relative to baseline. Demographic and outcome characteristics were compared between three cohorts: patients with normal baseline LVEF and no decrease on presentation, patients with decreased LVEF and no significant change, and those with a significant decrease in LVEF from their normal baseline (SIC). RESULTS: There were 110 patients that met inclusion criteria: 89 patients (81%) in the normal LVEF group, 12 (11%) in the prior decreased LVEF group, and 9 (8%) in the SIC group. Unadjusted mortality at 90 days for patients with SIC (67%) and prior decreased LVEF (58%) was significantly higher than those with normal EF (29%) (p = 0.019). When adjusted for age, gender, Charlson Index score, and lactate > 4.0 mmol/L, SIC was associated with mortality at 90 days (odds ratio 6.1, 95% confidence interval 1.37-32.92). CONCLUSION: SIC can be detected using FCU by emergency physicians in the ED and is associated with increased 90-day mortality.

Background Vascular access is a critical component of emergency department (ED) care. Ultrasound guided placement of peripheral intravenous (USIV) catheters is increasingly common. However, USIV are thought to suffer from reduced durability and higher complication rates. Extended dwell catheters (EDC) are long peripheral IVs placed under combined ultrasound and wire guidance. The goal of this study is to compare dwell times and complication rates of EDC to standard peripheral USIV. Methods We performed a retrospective cohort study at a tertiary care adult ED comparing IV placements during a 17-month period (8/1/2018-12/31/2019), stratified by standard USIV versus EDC. The primary outcome was catheter dwell time and secondary outcomes included need for inpatient vascular access team (VAST) consultation, peripherally inserted central catheter (PICC) insertions, and radiocontrast extravasations. Multivariable Cox regression time-to-event analyses were used to evaluate dwell times, adjusting for age, gender, BMI and end-stage renal disease. Results 359 EDC and 4190 standard USIV were included for analysis. Most USIV (95.6%) and EDC (98.3%) were placed by ED technicians trained in ultrasound vascular access. EDC median dwell time (5.9 days [95%CI: 5.1-6.7]) exceeded standard USIV (3.8 days [95% CI: 3.6-4.0]). Patients with EDC placed in the ED required less VAST consultation (0.84 vs 0.99 charges/encounter), had similar rates of PICC line use (8.0% vs 8.4% of encounters) and had no radiocontrast extravasation events. Multivariable Cox regression demonstrated survival benefit (longer dwell time) favoring EDC (HR 0.70 [95%CI 0.60-0.81]). Conclusion Use of EDC results in longer dwell time and reduces subsequent use of vascular access resources, while maintaining low complication rates. EDC demonstrate superior durability which may justify their selection over standard USIV in some patients.

Introduction: Emergency medicine (EM) is one of few specialties with variable training lengths. Hiring a three-year graduate to continue fellowship training in a department that supports a four-year residency program can lead to conflicts around resident supervision. We sought to understand hiring and clinical supervision, or staffing, patterns of non-Accreditation Council for Graduate Medical Education (ACGME) fellowships hosted at institutions supporting four-year residency programs. Methods: We performed a web-based, cross-sectional survey of non-ACGME fellowship directors (FD) hosted at institutions supporting four-year EM residency programs. We calculated descriptive statistics. Our primary outcome was the proportion of programs with four-year EM residencies that hire non-ACGME fellows graduating from three-year EM residencies. Results: Of 119 eligible FDs, 88 (74%) completed the survey. Seventy FDs (80%) indicated that they hire graduates of three-year residencies. Fifty-six (80%) indicated that three-year graduates supervise residents. Most FDs (74%) indicated no additional requirements exist to supervise residents outside of being hired as faculty. The FDs cited department policy, concerns about quality and length of training, and resident complaints as reasons for not hiring three-year graduates. A majority (10/18, 56%) noted that not hiring fellows from three-year programs negatively impacts recruitment and gives them access to a smaller applicant pool. Conclusion: Most non-ACGME fellowships at institutions with four-year EM programs recruit three-year graduates and allow them to supervise residents. This survey provides programs information on how comparable fellowships recruit and staff their departments, which may inform policies that fit the needs of their learners, the fellowship, and the department.

Objectives: There is no standardized protocol for performing educational point-of-care ultrasonography (POCUS) that addresses patient-centered ethical issues such as obtaining informed consent. This study sought to define principles for ethical application of educational POCUS and develop consensus-based best practice guidance. Methods: A questionnaire was developed by a trained ethicist after literature review with the help of a medical librarian. A diverse panel including experts in medical education, law, and bioethics; medical trainees; and individuals with no medical background was convened. The panel voted on their level of agreement with ethical principles and degree of appropriateness of behaviors in three rounds of a modified Delphi process. A high level of agreement was defined as 80% or greater consensus. Results: Panelists voted on 38 total items: 15 related to the patient consent and selection process, eight related to practices while performing educational POCUS, and 15 scenarios involving POCUS application. A high level of agreement was achieved for 13 items related to patient consent and selection, eight items related to performance practices, and 10 scenarios of POCUS application. Conclusions: Based on expert consensus, ethical best practices include obtaining informed consent before performing educational POCUS, allowing patients to decline educational POCUS, informing patients the examination is not intended to be a part of their medical evaluation and is not billed, using appropriate draping techniques, maintaining a professional environment, and disclosing incidental findings in coordination with the primary team caring for the patient. These practices could be implemented at institutions to encourage ethical use of educational POCUS when training physicians, fellows, residents, and medical students.
RESUMO
OBJECTIVES: Compliance with the fluid bonus component of the SEP-1 (severe sepsis and septic shock management) bundle remains poor due to concerns for iatrogenic harm from fluid overload. We sought to assess whether patients who received focused cardiac ultrasound (FCU) and were found to be fluid tolerant (FT) were more likely to receive the recommended 30 mL/kg fluid bolus within 3 hours of sepsis identification. DESIGN: Retrospective, observational cohort study. SETTING: University-affiliated, tertiary-care hospital in the United States. PATIENTS: Emergency department patients presenting with septic shock from 2018 to 2021. The primary exposure was receipt of FCU with identification of fluid tolerance 3 hours from onset of septic shock. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Two hundred ninety-two of 1,024 patients with septic shock received FCU within 3 hours of sepsis onset. One hundred seventy-seven were determined to be FT. One hundred fifteen patients were determined to have poor fluid tolerance (pFT). FT patients were more likely to reach the recommended 30 mL/kg fluid bolus amount compared with pFT (FT 52.0% vs. pFT 31.3%, risk difference: 20.7%, [95% CI, 9.4-31.9]). Patients who did not receive FCU met the bolus requirement 34.3% of the time. FT patients received more fluid within 3 hours (FT 2,271 mL vs. pFT 1,646 mL, mean difference 625 mL [95% CI, 330-919]). Multivariable logistic regression was used to estimate the association between fluid tolerance FCU findings and compliance with 30 mL/kg bolus after adjustment for patient characteristics and markers of hemodynamic instability. FT with associated with a higher likelihood of meeting bolus requirement (odds ratio 2.17 [1.52-3.12]). CONCLUSIONS: Patients found to be FT by FCU were more likely to receive the recommended 30 mL/kg bolus in the SEP-1 bundle when compared with patients found with pFT or those that did not receive FCU. There was no difference between groups in 28-day mortality, vasopressor requirement, or need for mechanical ventilation.
RESUMO
Audience: This ultrasound-guided regional anesthesia elective is designed for emergency medicine residents. Length of Curriculum: The proposed length of this curriculum is over one week. Introduction: Ultrasound-guided regional anesthesia (UGRA) is a useful tool in the emergency department (ED) for managing painful conditions, and many programs have identified that these are useful skills for emergency providers; however, only about 53% of programs report teaching UGRA as part of their core curriculum, and there currently are no widely available or peer reviewed nerve block curricula designed for emergency medicine residents. Educational Goals: To deliver an immersive 1-week elective to provide residents a strong foundation in principles of UGRA and an introduction to 14 nerve block procedures applicable to care provided in the ED. Educational Methods: The educational strategies used in this curriculum include: instructional videos, written and online independent learning materials, one-on-one teaching at the bedside with an emergency ultrasound fellow, simulation of nerve block techniques using a femoral nerve block task trainer, and performance of supervised nerve block procedures on patients in the ED. Research Methods: All residents provided feedback through an online survey after completing the elective. Results: Eight residents completed the elective in the first year of implementation. Following completion of the UGRA curriculum, 8/8 (100%) of residents reported increased level of confidence in performing UGRA. In addition, 8/8 (100%) of residents reported they were "likely" or "very likely" to incorporate UGRA into their future EM practice. All 8 (100%) residents responded they were "very likely" to recommend the elective to other trainees. The elective received high ratings for overall quality with an average rating of 9.4 out of 10 (±0.7). Discussion: An elective in ultrasound-guided regional anesthesia can be successfully incorporated into an emergency medicine training program. The curriculum was successful in providing focused training in UGRA and resulted in increased resident confidence in performing nerve block procedures. Topics: Ultrasound-guided regional anesthesia, nerve block, resident, elective, pain.
RESUMO
PROBLEM: The most effective way to train clinicians to safely don and doff personal protective equipment (PPE) and perform aerosol-generating procedures (AGPs), such as intubations, is unknown when clinician educators are unavailable, as they have been during the COVID-19 pandemic. Proper PPE and airway management techniques are critical to prevent the transmission of respiratory illnesses such as COVID-19. APPROACH: In March 2020, the authors implemented a structured train-the-trainers curriculum to teach PPE techniques and a modified airway management algorithm for suspected COVID-19 patients. A single emergency medicine physician trainer taught 17 subsequent emergency medicine and critical care physician trainers the proper PPE and airway management techniques. The initial trainer and 7 of the subsequent trainers then instructed 99 other emergency medicine resident and attending physicians using in situ simulation. Trainers and learners completed retrospective pre-post surveys to assess their comfort teaching the material and performing the techniques, respectively. OUTCOMES: The surveys demonstrated a significant increase in the trainers' comfort in teaching simulation-based education, from 4.00 to 4.53 on a 5-point Likert scale (P < .005), and in teaching the airway management techniques through simulation, from 2.47 to 4.47 (P < .001). There was no difference in the change in comfort level between those learners who were taught by the initial trainer and those who were taught by the subsequent trainers. These results suggest that the subsequent trainers were as effective in teaching the simulation material as the initial trainer. NEXT STEPS: Work is ongoing to investigate clinician- and patient-specific outcomes, including PPE adherence, appropriate AGP performance, complication rate, and learners' skill retention. Future work will focus on implementing similar train-the-trainers strategies for other health professions, specialties, and high-risk or rare procedures.

OBJECTIVES: Ultrasound-guided regional anesthesia (UGRA) can be a powerful tool in the treatment of painful conditions commonly encountered in emergency medicine (EM) practice. UGRA can benefit patients while avoiding the risks of procedural sedation and opioid-based systemic analgesia. Despite these advantages, many EM trainees do not receive focused education in UGRA and there is no published curriculum specifically for EM physicians. The objective of this study was to identify the components of a UGRA curriculum for EM physicians. METHODS: A list of potential curriculum elements was developed through an extensive literature review. An expert panel was convened that included 13 ultrasound faculty members from 12 institutions and from a variety of practice environments and diverse geographical regions. The panel voted on curriculum elements through two rounds of a modified Delphi process. RESULTS: The panelists voted on 178 total elements, 110 background knowledge elements, and 68 individual UGRA techniques. A high level of agreement was achieved for 65 background knowledge elements from the categories: benefits to providers and patients, indications, contraindications, risks, ultrasound skills, procedural skills, sterile technique, local anesthetics, and educational resources. Ten UGRA techniques achieved consensus: interscalene brachial plexus, supraclavicular brachial plexus, radial nerve, median nerve, ulnar nerve, serratus anterior plane, fascia iliaca, femoral nerve, popliteal sciatic nerve, and posterior tibial nerve blocks. CONCLUSIONS: The defined curriculum represents ultrasound expert opinion on a curriculum for training practicing EM physicians. This curriculum can be used to guide the development and implementation of more robust UGRA education for both residents and independent providers.
RESUMO
INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic presents unique challenges to frontline healthcare workers. In order to safely care for patients new processes, such as a plan for the airway management of a patient with COVID-19, must be implemented and disseminated in a rapid fashion. The use of in-situ simulation has been used to assist in latent problem identification as part of a Plan-Do-Study-Act cycle. Additionally, simulation is an effective means for training teams to perform high-risk procedures before engaging in the actual procedure. This educational advance seeks to use and study in-situ simulation as a means to rapidly implement a process for airway management in patients with COVID-19. METHODS: Using an airway algorithm developed by the authors, we designed an in-situ simulation scenario to train physicians, nurses, and respiratory therapists in best practices for airway management of patients with COVID-19. Physician participants were surveyed using a five-point Likert scale with regard to their comfort level with various aspects of the airway algorithm both before and after the simulation in a retrospective fashion. Additionally, we obtained feedback from all participants and used it to refine the airway algorithm. RESULTS: Over a two-week period, 93 physicians participated in the simulation. We received 81 responses to the survey (87%), which showed that the average level of comfort with personal protective equipment procedures increased significantly from 2.94 (95% confidence interval, 2.71-3.17) to 4.36 (4.24-4.48), a difference of 1.42 (1.20-1.63, p < 0.001). There was a significant increase in average comfort level in understanding the physician role with scores increasing from 3.51 (3.26-3.77) to 4.55 (2.71-3.17), a difference of 1.04 (0.82-1.25, p < 0.001). There was also increased comfort in performing procedural tasks such as intubation, from 3.08 (2.80-3.35) to 4.38 (4.23-4.52) after the simulation, a difference of 1.30 points (1.06-1.54, p < 0.001). Feedback from the participants also led to refinement of the airway algorithm. CONCLUSION: We successfully implemented a new airway management guideline for patients with suspected COVID-19. In-situ simulation is an essential tool for both dissemination and onboarding, as well as process improvement, in the context of an epidemic or pandemic.
