Introduction: Regional anesthesia aids in management of acute pain in the emergency department, but many emergency physicians remain inadequately trained. Further complicating medical education, our academic center continues to use remote learning as the primary setting for residency didactics. This project aims to create a remote conference session on ultrasound-guided serratus anterior plane blocks (USG-SAPB)., Methods: We used the ADDIE (analyze, design, develop, implement, evaluate) model for curricular design, with emergency medicine residents as our intended learners. For the analyze element, we examined clinical need and resident program evaluation feedback. For design, we utilized best practices for remote learning, principles of mental rehearsal, and multimodal instructional theory. For develop, we completed recruitment of faculty leads, materials, and beta testing of each component. We implemented our 50-minute session on the videoconferencing platform Zoom. For evaluate, we created a program evaluation survey based on Kirkpatrick's evaluation model., Results: Seventeen learners completed the evaluation. For Kirkpatrick level 1, 94% reported being very or extremely satisfied. For Kirkpatrick level 2, 91% ranked their presession confidence level in performing USG-SAPB as not at all or slightly confident, compared to the postsession, where 88% ranked themselves as moderately, very, or extremely confident. For Kirkpatrick level 3, 94% reported that they would incorporate at least a moderate amount of content into clinical practice., Discussion: This remote learning session on USG-SAPB demonstrated high levels of learner satisfaction, improvement in learner confidence, and potential to impact learners' clinical practice. Future studies can elucidate patient outcomes related to educational sessions., (© 2024 Weingart and Coneybeare.)

Background and Objectives: Severe pneumonia is the leading cause of death among young children worldwide, disproportionately impacting children who lack access to advanced diagnostic imaging. Here our objectives were to develop and test the accuracy of an artificial intelligence algorithm for detecting features of pulmonary consolidation on point-of-care lung ultrasounds among hospitalized children., Methods: This was a prospective, multicenter center study conducted at academic Emergency Department and Pediatric inpatient or intensive care units between 2018-2020. Pediatric participants from 18 months to 17 years old with suspicion of lower respiratory tract infection were enrolled. Bedside lung ultrasounds were performed using a Philips handheld Lumify C5-2 transducer and standardized protocol to collect video loops from twelve lung zones, and lung features at both the video and frame levels annotated. Data from both affected and unaffected lung fields were split at the participant level into training, tuning, and holdout sets used to train, tune hyperparameters, and test an algorithm for detection of consolidation features. Data collected from adults with lower respiratory tract disease were added to enrich the training set. Algorithm performance at the video level to detect consolidation on lung ultrasound was determined using reference standard diagnosis of positive or negative pneumonia derived from clinical data., Results: Data from 107 pediatric participants yielded 117 unique exams and contributed 604 positive and 589 negative videos for consolidation that were utilized for the algorithm development process. Overall accuracy for the model for identification and localization of consolidation was 88.5%, with sensitivity 88%, specificity 89%, positive predictive value 89%, and negative predictive value 87%., Conclusions: Our algorithm demonstrated high accuracy for identification of consolidation features on pediatric chest ultrasound in children with pneumonia.

Abstract: To address identified learning gaps among physician associates/assistants (PAs) working with point-of-care ultrasound (POCUS) in our ED, we designed and implemented a longitudinal POCUS curriculum. This curriculum introduced the 12 main POCUS applications for emergency medicine with presession educational assignments and in-person learning sessions. We used the Kirkpatrick framework of evaluation to develop our metrics of measurement. To examine the effect of the curriculum, pre- and postcurriculum surveys were completed and use of POCUS before, during, and after the curriculum period was monitored. Our results showed the curriculum increased confidence and knowledge of POCUS applications and significantly increased the use of POCUS clinically by PAs. Formal, on-the-job POCUS education for postgraduate PAs is a vital adjunct to informal clinical learning for PAs in emergency medicine to gain POCUS skills., (Copyright © 2023 American Academy of Physician Associates.)

Introduction: The American Board of Emergency Medicine recently established a new certification pathway in advanced emergency medicine ultrasound (AEMUS). Eligible applicants come from a wide range of experience but must pass the same examination to become certified. This study sought to evaluate a novel review course targeting a wide range of learners for a new examination., Methods: This was a cross-sectional study evaluating the outcomes of the American College of Emergency Physicians (ACEP) AEMUS review course. The program evaluation survey was designed to collect outcomes across multiple Kirkpatrick levels, including overall satisfaction, topic-specific satisfaction, topic-specific coverage, topic-specific confidence before and after the course, topic-specific perceived knowledge before and after the course, and changes in practice., Results: Seventy-four of 79 participants (93.7%) completed the survey. Mean course satisfaction was 4.59/5.00 (95% CI 4.47-4.72). Confidence to pass examination components increased for the following topics: administration, advanced left ventricle (LV), education, head and neck, hepatobiliary, male genitourinary, musculoskeletal, nonobstetric gynecology, pediatrics, physics, procedures, research, right ventricle, and venous/arterial. Perceived knowledge increased for the following topics: administration, advanced LV, education, head and neck, male genitourinary, musculoskeletal, pediatrics, physics, procedures, renal/bladder, research, right ventricle, and venous/arterial. Fifty-three of 74 participants (71.6%) stated they would change their practice based on the course. Examples of changes in practice include increased use of ultrasound for advanced abdominal, musculoskeletal, pediatric, and procedural applications. Future work will determine the impact on longer-term outcomes and focused practice designation (FPD) examination pass rates., Conclusion: The ACEP AEMUS FPD review course demonstrated high levels of satisfaction, increased participant confidence, increased perceived knowledge, and several self-reported changes in participants' ultrasound practice., Competing Interests: The authors declare no potential conflict of interest., (© 2022 Society for Academic Emergency Medicine.)

Background: Patients with coronavirus disease 2019 (COVID-19) present with diagnostic challenges because COVID-19 can cause varied end-organ failures that mimic respiratory distress of pulmonary origin. Early identification of concurrent complications can significantly alter patient management and course. Point-of-care ultrasound (POCUS) can be particularly useful in helping to differentiate concomitant complications with COVID-19. While lung POCUS findings related to COVID-19 have been published, little guidance exists on how ultrasound can be incorporated into a more comprehensive evaluation of patients under investigation for COVID-19., Objectives: We devised a pathway called COVUS that incorporates POCUS into the initial evaluation of patients under investigation for COVID-19 to guide diagnosis and management., Discussion: The pathway was derived based on a review of literature, consensus from the ultrasound faculty, as well as feedback from the entire faculty group at one academic institution with high volumes of patients with COVID-19. The scanning protocol uses a cardiac-first (rather than lung-first) approach to identify potential concomitant organ failure that may immediately alter management., Conclusions: COVUS aims to maximize identification of the most immediately life-threatening complications while minimizing time at bedside and provider risk of exposure to COVID-19., (Copyright © 2021 Elsevier Inc.
