Building a RAFFT: Impact of a professional development program for women faculty and residents in emergency medicine.

Background: Women comprise 28% of faculty in academic departments of emergency medicine (EM) and 11% of academic chairs. Professional development programs for women are key to career success and to prevent pipeline attrition. Within emergency medicine, there is a paucity of outcomes-level data for such programs. Objectives: We aim to measure the impact of a novel structured professional development curriculum and mentorship group (Resident and Faculty Female Tribe, or RAFFT) within an academic department of EM. Methods: This prospective single-center curriculum implementation and evaluation was conducted in the academic year 2020-2021. A planning group identified potential curricular topics using an iterative Delphi process. We developed a 10-session longitudinal curriculum; a postcurriculum survey was conducted to assess the perceived benefit of the program in four domains. Results: A total of 76% of 51 eligible women attended at least one session; for this project we analyzed the 24 participants (47%) who attended at least one session and completed both the pre- and the postsurvey. The majority of participants reported a positive benefit, which aligned with their expectations in the following areas: professional development (79.2%), job satisfaction (83.3%), professional well-being (70.8%), and personal well-being (79.2%). Resident physicians more often reported less benefit than expected compared to fellow/faculty physicians. Median perceived impact on career choice and trajectory was positive for all respondents. Conclusions: Success of this professional development program was measured through a perceived benefit aligning with participant expectations, a positive impact on career choice and career trajectory for participants in each career stage, and a high level of engagement in this voluntary program. Recommendations for the successful implementation of professional development programs include early engagement of stakeholders, the application of data from a program-specific needs assessment, early dissemination of session dates to allow for protected time off, and structured discussions with appropriate identification of presession resources.

Fungal Endophthalmitis on Ocular Ultrasound: A Case Report.

INTRODUCTION: Endophthalmitis is a rare intraocular infection caused by numerous organisms from several possible sources. Fungal endophthalmitis is a rare subset of this pathology with limited diagnostics available. One of the few options to make this diagnosis is vitreous sampling, which is invasive, and results are not immediately available. CASE REPORT: This case report describes the successful use of point-of-care ultrasound to visualize an intraocular fungal mass in a 60-year-old male who presented to the emergency department (ED) with two weeks of left eye pain and erythema approximately two months postoperative from a cataract extraction surgery. CONCLUSION: Fungal endophthalmitis is a rare and challenging diagnosis. Methods of diagnosing this pathology are not readily available in the ED. Point-of-care ultrasound may be a useful adjunct for the prompt diagnosis of fungal endophthalmitis.

Language of transducer manipulation 2.0: continuing to codify terms for effective teaching.

OBJECTIVES: Accurate communication is an integral component of ultrasound education. In light of the recent global pandemic, this has become even more crucial as many have moved to virtual education out of necessity. Several studies and publications have sought to establish common terminology for cardinal ultrasound probe motions. To date, no studies have been performed to determine which of these terms have been adopted by the ultrasound community at large. METHODS: A survey was developed which asked respondents to describe videos of six common probe motions in addition to providing basic demographic and training data. The survey was disseminated electronically across various academic listservs and open access resources. RESULTS: Data were collected over a 6-week period and yielded 418 unique responses. Responses demonstrated significant variation in terminology related to all 6 cardinal probe motions. While some degree of difference in response can be accounted for by discipline of training, inter-group variation still exists in terminology to describe common probe motions. Of the survey respondents, 57.5% felt that inconsistent probe motion terminology made teaching ultrasound more difficult. CONCLUSIONS: The results demonstrate that despite efforts to codify probe motions, variation still exists between ultrasound practitioners and educators in the description of cardinal probe motions. This lack of consensus can contribute to challenges in both virtual and in-person ultrasound education.

ITSUS: Integrated, Tiered, Self-Directed Ultrasound Scanning for Learning Anatomy.

Ultrasound is being introduced into many medical schools and incorporated into the anatomy curriculum; however, in most cases, this consists of proctored sessions which can be limited by faculty time and availability. Additionally, the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has significantly impacted medical education, especially ultrasound education, which has traditionally depended on hands-on practice and instruction. A structured, independent, hands-on learning curriculum using ultrasound would have many benefits. In this study, eight self-guided system-based modules were developed mirroring the undergraduate anatomy curriculum. For each scan, a beginner, intermediate, and advanced component was designed. Each module contains clear, stepwise directions for image acquisition, optimization, and interpretation of the anatomical structures and suggestions for troubleshooting. Students save ultrasound images as part of their digital portfolios for review with ultrasound faculty. This design provides an educational model to increase medical student opportunities for independent, structured, self-directed anatomy learning with ultrasound that can be integrated with existing educational programs.

Defining an Ultrasound-guided Regional Anesthesia Curriculum for Emergency Medicine.

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.

Billing I-AIM: a novel framework for ultrasound billing.

BACKGROUND: Point-of-care ultrasound (POCUS) has an ever-growing footprint in medicine. With this growth POCUS billing and reimbursement has become an area gaining quite a bit of attention as a means of funding and sustaining quality and education programs. Standardization across providers is needed to improve the financial viability of POCUS. RESULTS: We created an institutional collaborative which developed a framework to identify critical POCUS billing and reimbursement checkpoints. The framework, Billing I-AIM, provides a feasible structure to enhance provider-based reimbursement and perform quality improvement efforts across variable POCUS environments. CONCLUSIONS: POCUS billing using the Billing I-AIM technique allows administrative oversight, quality assurance, and educational functions as well. A discussion of the framework and respective application is provided.

A seven-center examination of the relationship between monthly volume and mortality in trauma: a hypothesis-generating study.

INTRODUCTION: The relationship between trauma volumes and patient outcomes continues to be controversial, with limited data available regarding the effect of month-to-month trauma volume variability on clinical results. This study examines the relationship between monthly trauma volume variations and patient mortality at seven Level I Trauma Centers located in the Eastern United States. We hypothesized that higher monthly trauma volumes may be associated with lower corresponding mortality. METHODS: Monthly patient volume data were collected from seven Level I Trauma Centers. Additional information retrieved included monthly mortality, demographics, mean monthly injury severity (ISS), and trauma mechanism (blunt versus penetrating). Mortality was utilized as the primary study outcome. Statistical corrections for mean age, gender distribution, ISS, and mechanism of injury were made using analysis of co-variance (ANCOVA). Center-specific, annually-adjusted median monthly volumes (CSAA-MMV) were calculated to standardize patient volume differences across participating institutions. Statistical significance was set at α < 0.05. RESULTS: A total of 604 months of trauma admissions, encompassing 122,197 patients, were analyzed. Controlling for patient age, gender, ISS, and mechanism of injury, aggregate data suggested that monthly trauma volumes < 100 were associated with significantly greater mortality (3.9%) than months with volumes > 400 (mortality 2.9%, p < 0.01). To account for differences in monthly volumes between centers, as well as for temporal bias associated with potential differences over the entire study duration period, data were normalized using CSAA-MMV as a standardized reference point. Monthly volumes ≤ 33% of the CSAA-MMV were associated with adjusted mortality of 5.0% whereas monthly volumes ≥ 134% CSAA-MMV were associated with adjusted mortality of 2.7% (p < 0.01). CONCLUSIONS: This hypothesis-generating study suggests that greater monthly trauma volumes appear to be associated with lower mortality. In addition, our data also suggest that across all participating centers mortality may be a function of relative month-to-month volume variation. When normalized to institution-specific, annually-adjusted "median" monthly trauma contacts, we show that months with patient volumes ≤ 33% median may be associated with subtly but not negligibly (1.4-2.3%) higher mortality than months with patient volumes ≥ 134% median.

CLEAR: A Novel Approach to Ultrasound Equipment Homeostasis.

Protocols for the sanitation and maintenance of point-of-care ultrasound (US) equipment are lacking. This study introduces the CLEAR protocol (clean, locate, energize, augment supplies, and remove patient identifiers) as a tool to improve the readiness of US equipment, termed US equipment homeostasis. The state of US equipment homeostasis in the emergency department of a single academic center was investigated before and after implementing this protocol, with an improvement in outcomes. These findings demonstrate that the CLEAR protocol can improve US homeostasis. CLEAR can function as a teaching tool to promote homeostasis as well as a checklist to assess compliance.

Documenting the Growth of Ultrasound Research in Emergency Medicine Through a Bibliometric Analysis of Accepted Academic Conference Abstracts.

OBJECTIVES: Ultrasound (US) has become an indispensable skill for emergency physicians. Growth in the use of US in emergency medicine (EM) has been characterized by practice guidelines, education requirements, and the number of EM US practitioners. Our purpose was to further document the growth of EM US by profiling the breadth, depth, and quality of US-related research presented at EM's most prominent annual research conference: the Society for Academic Emergency Medicine Annual Meeting. METHODS: We reviewed published research abstracts from the annual Society for Academic Emergency Medicine conferences from 1999 to 2015. Abstracts related to US were identified and examined for the number of authors and rigor of the research design. Designs were categorized as experimental, quasiexperimental, and nonexperimental. Abstract submissions were analyzed by the average rate of change over time. RESULTS: From 1999 to 2015, we observed a 10.2% increase in the number of accepted abstracts related to US research. This rate compared to a 3.2% average rate of change for all abstracts in general. The number of unique authors engaged in US research increased at a rate of 26.6%. Of the 602 abstracts identified as US related, only 12% could be considered experimental research. CONCLUSIONS: We observed larger increases in the number of US-related research relative to the total number of abstracts presented at a national conference. The number of investigators engaging in this research has also steadily increased. The research design of these studies was found to be primarily quasiexperimental. To improve the quality of EM's use of point-of-care US, more rigorous research with experimental designs is needed.

Inferior Vena Cava Measurement with Ultrasound: What Is the Best View and Best Mode?

INTRODUCTION: Intravascular volume status is an important clinical consideration in the management of the critically ill. Point-of-care ultrasonography (POCUS) has gained popularity as a non-invasive means of intravascular volume assessment via examination of the inferior vena cava (IVC). However, there are limited data comparing different acquisition techniques for IVC measurement by POCUS. The goal of this evaluation was to determine the reliability of three IVC acquisition techniques for volume assessment: sub-xiphoid transabdominal long axis (LA), transabdominal short axis (SA), and right lateral transabdominal coronal long axis (CLA) (aka "rescue view"). METHODS: Volunteers were evaluated by three experienced emergency physician sonographers (EP). Gray scale (B-mode) and motion-mode (M-mode) diameters were measured and IVC collapsibility index (IVCCI) calculated for three anatomic views (LA, SA, CLA). For each IVC measurement, we calculated descriptive statistics, intra-class correlation coefficients (ICC), and two-way univariate analyses of variance. RESULTS: EPs evaluated 39 volunteers, yielding 351 total US measurements. Measurements of the three views had similar means (LA 1.9 ± 0.4cm; SA 1.9 ± 0.4cm; CLA 2.0 ± 0.5cm). For B-Mode, LA had the highest ICC (0.86, 95% CI [0.76-0.92]) while CLA had the poorest ICC (0.74, 95% CI [0.56-0.85]). ICCs for all M-mode IVCCI were low. Significant interaction effects between anatomical view and EP were observed for B-mode and M-mode measurements. Post-hoc analyses revealed difficulty in consistent view acquisition between EPs. CONCLUSION: Inter-rater reliability of the IVC by EPs was highest for B-mode LA and poorest for all M-Mode IVC collapsibility indices (IVCCI). These results suggest that B-mode LA holds the most promise to deliver reliable measures of IVC diameter. Future studies may focus on validation in a clinical setting as well as comparison to a reference standard.

The right team at the right time - Multidisciplinary approach to multi-trauma patient with orthopedic injuries.

Integrated, multidisciplinary team approach to the multiply injured patient can help optimize care, minimize morbidity, and reduce mortality. It also provides a framework for accelerated postinjury rehabilitation course. The characteristics and potential benefits of this approach, including team dynamics and interactions, are discussed in this brief review. Emphasis is placed on synergies provided by specialty teams working together in the framework of care coordination, timing of surgical and nonsurgical interventions, and injury/physiologic considerations.

Longitudinal Ultrasound Education Track Curriculum Implemented Within an Emergency Medicine Residency Program.

Emergency Medicine residency programs offer ultrasound-focused curricula to address Accreditation Council for Graduate Medical Education (ACGME) milestones. Although some programs offer advanced clinical tracks in ultrasound, no standard curriculum exists. We sought to establish a well-defined ultrasound track curriculum to allow interested residents to develop advanced clinical skills and scholarship within this academic niche. The curriculum involves a greater number of clinical scans, ultrasound-focused scholarly and quality improvement projects, enhanced faculty-driven ultrasound focused didactics, and participation at a national ultrasound conference to receive certification. Successful ultrasound scholarly tracks can provide residents with the potential to obtain fellowships or competency beyond ACGME requirements.

Language of Transducer Manipulation: Codifying Terms for Effective Teaching.

There is a need for consistent, repetitive, and reliable terminology to describe the basic manipulations of the ultrasound transducer. Previously, 5 basic transducer motions have been defined and used in education. However, even with this effort, there is still a lack of consistency and clarity in describing transducer manipulation and motion. In this technical innovation, we describe an expanded definition of transducer motions, which include movements to change the transducer's angle of insonation to the target as well as the location on the body to optimize the ultrasound image. This new terminology may allow for consistent teaching and improved communication in the process of image acquisition.

Sonographic evaluation of intravascular volume status: Can internal jugular or femoral vein collapsibility be used in the absence of IVC visualization?

INTRODUCTION: Inferior vena cava collapsibility index (IVC-CI) has been shown to correlate with both clinical and invasive assessment of intravascular volume status, but has important limitations such as the requirement for advanced sonographic skills, the degree of difficulty in obtaining those skills, and often challenging visualization of the IVC in the postoperative patient. The current study aims to explore the potential for using femoral (FV) or internal jugular (IJV) vein collapsibility as alternative sonographic options in the absence of adequate IVC visualization. METHODS: A prospective, observational study comparing IVC-CI and Fem- and/or IJV-CI was performed in two intensive care units (ICU) between January 2012 and April 2014. Concurrent M-mode measurements of IVC-CI and FV- and/or IJV-CI were collected during each sonographic session. Measurements of IVC were obtained using standard technique. IJV-CI and FV-CI were measured using high-frequency, linear array ultrasound probe placed in the corresponding anatomic areas. Paired data were analyzed using coefficient of correlation/determination and Bland-Altman determination of measurement bias. RESULTS: We performed paired ultrasound examination of IVC-IJV (n = 39) and IVC-FV (n = 22), in 40 patients (mean age 54.1; 40% women). Both FV-CI and IJV-CI scans took less time to complete than IVC-CI scans (both, P < 0.02). Correlations between IVC-CI/FV-CI (R(2) = 0.41) and IVC-CI/IJV-CI (R(2) = 0.38) were weak. There was a mean -3.5% measurement bias between IVC-CI and IJV-CI, with trend toward overestimation for IJV-CI with increasing collapsibility. In contrast, FV-CI underestimated collapsibility by approximately 3.8% across the measured collapsibility range. CONCLUSION: Despite small measurement biases, correlations between IVC-CI and FV-/IJV-CI are weak. These results indicate that IJ-CI and FV-CI should not be used as a primary intravascular volume assessment tool for clinical decision support in the ICU. The authors propose that IJV-CI and FV-CI be reserved for clinical scenarios where sonographic acquisition of both IVC-CI or subclavian collapsibility are not feasible, especially when trended over time. Sonographers should be aware that IJV-CI tends to overestimate collapsibility when compared to IVC-CI, and FV-CI tends to underestimates collapsibility relative to IVC-CI.

Geriatric-specific triage criteria are more sensitive than standard adult criteria in identifying need for trauma center care in injured older adults.

STUDY OBJECTIVE: We evaluate the sensitivity of Ohio's 2009 emergency medical services (EMS) geriatric trauma triage criteria compared with the previous adult triage criteria in identifying need for trauma center care among older adults. METHODS: We studied a retrospective cohort of injured patients aged 16 years or older in the 2006 to 2011 Ohio Trauma Registry. Patients aged 70 years or older were considered geriatric. We identified whether each patient met the geriatric and the adult triage criteria. The outcome measure was need for trauma center care, defined by surrogate markers: Injury Severity Score greater than 15, operating room in fewer than 48 hours, any ICU stay, and inhospital mortality. We calculated sensitivity and specificity of both triage criteria for both age groups. RESULTS: We included 101,577 patients; 33,379 (33%) were geriatric. Overall, 57% of patients met adult criteria and 68% met geriatric criteria. Using Injury Severity Score, for older adults geriatric criteria were more sensitive for need for trauma center care (93%; 95% confidence interval [CI] 92% to 93%) than adult criteria (61%; 95% CI 60% to 62%). Geriatric criteria decreased specificity in older adults from 61% (95% CI 61% to 62%) to 49% (95% CI 48% to 49%). Geriatric criteria in older adults (93% sensitivity, 49% specificity) performed similarly to the adult criteria in younger adults (sensitivity 87% and specificity 44%). Similar patterns were observed for other outcomes. CONCLUSION: Standard adult EMS triage guidelines provide poor sensitivity in older adults. Ohio's geriatric trauma triage guidelines significantly improve sensitivity in identifying Injury Severity Score and other surrogate markers of the need for trauma center care, with modest decreases in specificity for older adults.

The ultrasound challenge 2.0: introducing interinstitutional competition in medical student ultrasound education.

The Ultrasound Challenge was developed at The Ohio State University College of Medicine to introduce focused ultrasound to medical students. The goal was to develop experience in ultrasound through practice and competition. Initially this competition was held between Ohio State University College of Medicine students from years 1 through 4. The Ultrasound Challenge 2.0 was held in 2013. The event expanded on the previous structure by including students from the Wayne State University College of Medicine. The goal of this article is to describe our experiences with expansion of our interinstitutional ultrasound event. The challenge consisted of 6 stations: focused assessment with sonography for trauma, aortic ultrasound, cardiac ultrasound, pelvic ultrasound, musculoskeletal ultrasound, and vascular access. The participants were given a handbook outlining the expectations for each station ahead of time. Vascular access was graded in real time using the Brightness Mode Quality Ultrasound Imaging Examination Technique (B-QUIET) method. The remainder were timed, saved, and graded after the event by 3 independent faculty members using the B-QUIET method. The highest score with the fastest time was the winner. The Ultrasound Challenge 2.0 included 40 participants: 31 from The Ohio State University College of Medicine and 9 from the Wayne State University College of Medicine. The makeup of the winners in all categories consisted of 1 first-year medical student, 7 second-year medical students, 3 third-year medical students, and 10 fourth-year medical students. The Ultrasound Challenge 2.0 was a success for those who participated. It provided the first known interinstitutional medical student ultrasound competition. Students from both institutions were able to practice their image acquisition skills, demonstrate abilities in a competitive environment, and develop collegiality and teamwork.
