Interrater Reliability of Point-of-Care Cardiopulmonary Ultrasound in Patients With Septic Shock: An Analysis of Agreement Between Treating Clinician and Expert Reviewers.

BACKGROUND: Cardiopulmonary ultrasound (CPUS) is commonly used to assess cardiac function and preload status in patients with septic shock. However, the reliability of CPUS findings at the point of care is unknown. OBJECTIVE: To assess interrater reliability (IRR) of CPUS in patients with suspected septic shock between treating emergency physicians (EPs) vs emergency ultrasound (EUS) experts. METHODS: Single-center, prospective, observational cohort enrolling patients (n = 51) with hypotension and suspected infection. Treating EPs performed and interpreted CPUS for cardiac function parameters (left ventricular [LV] function and right ventricular [RV] function and size) and preload volume parameters (inferior vena cava [IVC] diameter and pulmonary B-lines). The primary outcome was IRR (assessed by Kappa values [κ] and intraclass correlation coefficient [ICC]) between EP and EUS-expert consensus. Secondary analyses examined the effects on IRR of operator experience, respiratory rate, and known difficult views on a Cardiology-performed echocardiogram. RESULTS: IRR was fair for LV function, κ = 0.37, 95% confidence interval (CI) 0.1-0.64; poor for RV function, κ = -0.05, 95% CI -0.6-0.5; moderate for RV size, κ = 0.47, 95% CI 0.07-0.88; and substantial for B-lines, κ = 0.73, 95% CI 0.51-0.95 and IVC size, ICC = 0.87, 95% CI 0.2-0.99. Involvement of ultrasound-trained faculty was associated with improved IRR of RV size (p = 0.002), but not other CPUS domains. CONCLUSIONS: Our study demonstrated high IRR for preload volume parameters (IVC size and presence of B-lines), but not for cardiac parameters (LV function and RV function and size) in patients presenting with concern for septic shock. Future research must focus on determining sonographer and patient-specific factors affecting CPUS interpretation in real-time.

A Multicenter, Prospective Study Comparing Subxiphoid and Parasternal Views During Brief Echocardiography: Effect on Image Quality, Acquisition Time, and Visualized Anatomy.

BACKGROUND: Recent literature has suggested echocardiography (echo) may prolong pauses in chest compressions during cardiac arrest. OBJECTVES: We sought to determine the impact of the sonographic approach (subxiphoid [SX] vs. parasternal long [PSL]) on time to image completion, image quality, and visualization of cardiac anatomy during echo, as performed during Advanced Cardiac Life Support. METHODS: This was a multicenter, randomized controlled trial conducted at 29 emergency departments (EDs) assessing the time to image acquisition and image quality between SX and PSL views for echo. Patients were enrolled in the ED and imaged in a simulated cardiac arrest scenario. Clinicians experienced in echo performed both SX and PSL views, first view in random order. Image quality and time to image acquisition were recorded. Echos were evaluated for identification of cardiac landmarks. Data are presented as percentages or medians with interquartile ranges (IQRs). RESULTS: We obtained 6247 echo images, comprising 3124 SX views and 3123 PSL. Overall time to image acquisition was 9.0 s (IQR 6.7-14.1 s). Image acquisition was shorter using PSL (8.8 s, IQR 6.5-13.5 s) compared with SX (9.3 s, IQR 6.7-15.0 s). The image quality was better with the PSL view (3.86 vs. 3.54; p < 0.0001), twice as many SX images scoring in the worst quality category compared with PSL (8.6% vs. 3.7%). Imaging of the pericardium, cardiac chambers, and other anatomic landmarks was superior with PSL imaging. CONCLUSIONS: Echo was performed in < 10 s in > 50% of patients using either imaging technique. Imaging using PSL demonstrated improved image quality and improved identification of cardiac landmarks.

Prehospital Echocardiogram Use in Identifying Massive Pulmonary Embolism in Unidentified Respiratory Failure.

Medical transport teams often handle cases of complex, critically ill patients and are in need of rapid, bedside assessments to guide clinical decision making. The use of point-of-care ultrasound (POCUS) as a diagnostic indicator has gained increased acceptance in emergency medicine. Ultrasound devices have become increasingly portable, and numerous studies have demonstrated that use in the prehospital setting is feasible, accurate, and can have a dramatic impact on the care of patients. In this case report, we highlight the use of handheld ultrasound in the identification of right heart dilation in an unstable patient with respiratory failure in a rural emergency department, concerning for massive pulmonary embolism. The patient was given thrombolytic therapy with dramatic clinical improvement, ultimately surviving transport to the intensive care unit at a nearby tertiary care center.

Assessment of dynamic changes in cardiac function during resuscitation of patients with suspected septic shock: A prospective, observational, cohort study.

STUDY OBJECTIVE: To describe changes in cardiac function throughout the course of resuscitation of patients with suspected septic shock. METHODS: Prospective observational cohort study of Point-of-Care Transthoracic Echocardiograms (TTE) obtained in Emergency Department (ED) patients with a presumed infectious cause of hypotension within one hour of initiating IV fluid resuscitation. Findings of this pre-resuscitation TTE were compared to mid-resuscitation TTE (obtained upon disposition from the ED), and post-resuscitation TTE (obtained after admission to hospital). RESULTS: 22 enrolled patients had a second TTE available for comparison to the initial, pre-resuscitation TTE. 12 patients had a mid-resuscitation TTE and 16 patients had a post-resuscitation TTE. We observed a high incidence of changes on TTE during the clinical course of resuscitation (14/22 [64%]). Patients who developed LV or RV dysfunction during resuscitation were more likely to require vasopressor infusion and ICU admission (Spearman's coefficients [95% CI] of 0.68 [0.36-0.86] and 0.47 [0.04;0.75] respectively). Development of RV dysfunction alone was associated with increased use of positive pressure ventilation and vasopressor infusion (Spearman's coefficients [95% CI] of 0.43 [0;0.72] and 0.47 [0.05,0.75] respectively). CONCLUSIONS: Cardiac function changes assessed by TTE are common during the resuscitation of patients with septic shock. These changes likely reflect the underlying physiology of patients with septic shock and correlate with need for interventions and higher level of care. Further work is required to characterize these changes and to elucidate how to use these physiologic data to guide management.

Ultrasound simulation utilization among point of care ultrasound users: Results of a survey.

PURPOSE: While ultrasound simulation devices have long been available as adjuncts to ultrasound education, it is unclear how they are used. We conducted a survey to determine the current utilization of emergency point-of-care ultrasound simulation and describe the current trends in the use of ultrasound simulation. METHODS: A survey was sent to 1270 members of the American College of Emergency Physicians Ultrasound Section via email. The survey listed 23 questions that queried how survey participants used ultrasound simulation devices. RESULTS: One hundred and fifty-one survey responses were collected. The majority of survey respondents (83%) indicated that ultrasound simulation devices are available at their institution, with nearly half (45%) survey participants reporting both high- and low-fidelity ultrasound simulators available, and fewer describing low-fidelity simulators only (33%) or high-fidelity simulators only (5%). Most respondents (84%) with ultrasound simulators use them for training residents, students, fellows, and faculty. Only 20% of survey participants use ultrasound simulators for credentialing purposes. CONCLUSIONS: Ultrasound simulation devices are widespread amongst our survey respondents, who represent a small percentage of the ACEP ultrasound section. Ultrasound simulators are used to help ultrasound learners at various levels of training.

What You Didn't Learn in Residency: A Collective Curriculum for New Academic EM Faculty and Fellows.

Audience and Type of Curriculum: This curriculum is designed for emergency medicine fellows and first-year junior faculty. The curriculum covers core topics related to academic and professional success for an early career faculty member. Length of Curriculum: The curriculum is designed as quarterly sessions over the course of one academic year. Introduction: An increasing number of emergency medicine graduates are pursuing fellowship after completion of residency.1 Fellowship can be challenging as newly minted graduates begin to explore their academic niche, refine their clinical practice, and define their personal and professional spheres. We propose a structured curriculum to help guide fellows and new faculty to mitigate these challenges. Educational Goals: The aim of this curriculum is to develop relevant skills to promote academic success for fellows and first-year faculty at the start of their academic career and which could be completed during a one-year training timeline. We included topics relevant to all fellow and new faculty's expected personal and professional journey during this first year, including time management, academic productivity, resilience/wellness, and developing a national reputation. Educational Methods: The educational strategies used in this curriculum consist primarily of lecture seminars. There is one short individual activity associated with the lectures and one small group discussion. Research Methods: The course was assessed with pre- and post-test surveys following each lecture. Surveys assessed participants' reaction, learning, and behavior for each session. Evaluations were completed based on a 5-point Likert scale (1=strongly disagree, 5=strongly agree). Results: Fifteen participants attended the seminar series encompassing fellows and first-year faculty/post-fellows from ten different fellowship subspecialities. Average pre-assessment scores were low for many of the self-reported skills and confidence throughout the seminar series. Overall, participants reported increased confidence on the post-test for each of the seminar topics. In addition, participants reported that they learned new skills and planned to use the new ideas presented. All participants reported they would recommend these seminars to someone else on their same career path. Discussion: Overall, participants reported increased confidence, new skills, and plans to use the ideas presented in the seminar series. The content appears applicable to this learner set since all reported they would recommend the series to others on their career path. In conclusion, we believe our seminar series will build skills for fellows and first-year faculty which will promote academic success. Topics: Academic success, professional development, early career development.

Use of Point-of-Care Ultrasound in the Pediatric and Neonatal Emergency Transport Realm.

Point-of-care ultrasound (POCUS) is a tool often used by clinical providers in the care of critically ill or acutely injured patients. POCUS can be used to evaluate for potentially harmful conditions during transport and to optimize downstream management. Although available literature primarily focuses on adults in the prehospital, critical care, and austere environment realm, more literature supporting POCUS use during pediatric and neonatal transport has emerged over the last few years. What is currently available is often from diverse operators and a wide variety of applications. The goal of this article is to describe current pediatric and neonatal POCUS applications and to identify its barriers and limitations in the transport realm. [Pediatr Ann. 2021;50(10):e432-e436.].

Integration of Lung Point-of-care Ultrasound into Clinical Decision Making for Medical Students in Simulated Cases.

BACKGROUND: Point-of-care ultrasound (POCUS) has an emerging presence in medical student education; however, there is limited evidence that this translates into appropriate clinical care. We aimed to evaluate the ability of medical students to integrate newly obtained POCUS knowledge into simulated clinical cases. METHODS: We conducted an observational study of medical students participating in a mandatory rotation during their clinical years. Students in small groups underwent formalized lung POCUS lectures and hands-on training. Students participated in simulated "dyspnea" cases focused on either congestive heart failure (CHF) or chronic obstructive pulmonary disease (COPD). They were observed for critical actions including elements related to medical decision-making and ultrasound use and interpretation. Ultrasound-specific written knowledge was gauged with a short assessment after the first lecture and at week 4. RESULTS: A total of 62 students participated and were observed during simulations. All groups correctly identified and treated CHF in the simulated case. Most groups (7 out of 9) attempted to use ultrasound in the CHF case; five groups correctly recognized B-lines; and four groups correctly interpreted B-lines as pulmonary edema. No groups used ultrasound in the COPD case. CONCLUSION: Most students attempted to use ultrasound during simulated CHF cases after a brief didactic intervention; however, many students struggled with clinical application. Interestingly, no students recognized the need to apply ultrasound for diagnosis and management of COPD. Future studies are needed to better understand how to optimize teaching for medical students to improve translation into POCUS skills and improved clinical practice.

Tools for Measuring Clinical Ultrasound Competency: Recommendations From the Ultrasound Competency Work Group.

Competency in clinical ultrasound is essential to ensuring safe patient care. Competency in clinical ultrasound includes identifying when to perform a clinical ultrasound, performing the technical skills required for ultrasound image acquisition, accurately interpreting ultrasound images, and incorporating sonographic findings into clinical practice. In this concept paper, we discuss the advantages and limitations of existing tools to measure ultrasound competency. We propose strategies and future directions for assessing competency in clinical ultrasound.

Identifying and Overcoming Barriers to Resident Use of Point-of-Care Ultrasound.

INTRODUCTION: Emergency medicine residency programs have rigorous point-of-care ultrasound (POCUS) curricula. However, this training does not always readily translate to routine use in clinical decision-making. This study sought to identify and overcome barriers that could prevent resident physicians from performing POCUS during clinical shifts. METHODS: This was a two-step process improvement study. First, a survey was deployed to all residents of a three-year academic residency program to identify barriers to clinical use of POCUS. This survey identified the perceived lack of a uniform documenting protocol as the most important barrier to performing POCUS on shift. Second, as an intervention to overcome this barrier, a streamlined documentation protocol was developed and presented to residents. The primary outcome was the number of patients who had POCUS used in medical decision-making one year before and after intervention. Secondary outcomes were the level of training of residents performing exams and whether faculty overseeing exams were trained through an ultrasound fellowship program. RESULTS: POCUS use by residents increased from 82 to 223 patients before and after the intervention, respectively. Per resident, this translates to an absolute increase from 2.2 (95% confidence intervall [CI], 1.4, 3) to 5.8 (95% CI, 4, 7.6) or 3.6 (95% CI, 1.8, 5.4) exams/resident over the study period. We observed no significant difference in the proportions of scans attributable to the resident level of training (χ2 = 0.5, p = 0.47). The proportion of exams by non-ultrasound fellowship trained faculty increased significantly more compared to fellowship trained faculty (χ2 = 19, p<0.0001); however, both ultrasound fellowship trained and non-ultrasound fellowship trained faculty increased the absolute number of exams performed. CONCLUSION: A key perceived barrier to resident-performed POCUS is unfamiliarity with documenting ultrasounds for medical decision-making. Educating residents in person about a POCUS documentation protocol may help overcome this barrier. Incorporating resident input and motivation into POCUS incentivization may increase utilization. Future studies in optimizing POCUS on shift will need to focus on streamlining documentation, addressing time constraints, and faculty support for resident-performed POCUS.

Simulation Training to Maintain Neonatal Resuscitation and Pediatric Sedation Skills for Emergency Medicine Faculty.

BACKGROUND: Neonatal resuscitations and significant adverse cardiorespiratory events during pediatric sedations are infrequent. Thus, it is challenging to maintain the skills necessary to manage patients experiencing these events. As the pediatric emergency medicine specialty expands, exposure of general emergency medicine physicians to these potentially critical patients may become even more limited. As such, effective training strategies need to be developed. Simulation provides the opportunity to experience a rare event in a safe learning environment, and has shown efficacy in skill acquisition for medical students and residents. Less is known regarding its use for faculty-level learners. OBJECTIVES: To assess the acceptability, efficacy, and feasibility of a simulation-based educational intervention for emergency medicine faculty on their knowledge, comfort, and perceived competence in neonatal resuscitation and pediatric sedation skills. METHODS: Eighteen academic emergency medicine faculty participated in a 4-hour educational intervention with high-fidelity simulation sessions focused on neonatal resuscitation (precipitous delivery of a depressed newborn) and adverse events associated with pediatric sedation (laryngospasm and hypoventilation). Faculty also practiced umbilical vein catheterization, video laryngoscopy skills, and reviewed supplies stocked in our pediatric resuscitation cart. A pre- and postintervention evaluation was completed consisting of knowledge and attitude questions. Paired t test analysis was used to detect statistically significant change (P ≤ 0.05). RESULTS: Results were obtained from 17 faculty members. Simulation training was well accepted pre- and postintervention, and simulation was effective with statistically significant improvement in both knowledge and attitude. This type of event was feasible with 83% of emergency medicine faculty participating. CONCLUSION: Emergency medicine faculty have limited opportunities to manage neonatal resuscitations and adverse events in pediatric sedations. Simulation training appears to be an effective educational modality to help maintain these important skills.

Comparison of a multimedia simulator to a human model for teaching FAST exam image interpretation and image acquisition.

OBJECTIVES: This study compared the effectiveness of a multimedia ultrasound (US) simulator to normal human models during the practical portion of a course designed to teach the skills of both image acquisition and image interpretation for the Focused Assessment with Sonography for Trauma (FAST) exam. METHODS: This was a prospective, blinded, controlled education study using medical students as an US-naïve population. After a standardized didactic lecture on the FAST exam, trainees were separated into two groups to practice image acquisition on either a multimedia simulator or a normal human model. Four outcome measures were then assessed: image interpretation of prerecorded FAST exams, adequacy of image acquisition on a standardized normal patient, perceived confidence of image adequacy, and time to image acquisition. RESULTS: Ninety-two students were enrolled and separated into two groups, a multimedia simulator group (n = 44), and a human model group (n = 48). Bonferroni adjustment factor determined the level of significance to be p = 0.0125. There was no difference between those trained on the multimedia simulator and those trained on a human model in image interpretation (median 80 of 100 points, interquartile range [IQR] 71-87, vs. median 78, IQR 62-86; p = 0.16), image acquisition (median 18 of 24 points, IQR 12-18 points, vs. median 16, IQR 14-20; p = 0.95), trainee's confidence in obtaining images on a 1-10 visual analog scale (median 5, IQR 4.1-6.5, vs. median 5, IQR 3.7-6.0; p = 0.36), or time to acquire images (median 3.8 minutes, IQR 2.7-5.4 minutes, vs. median = 4.5 minutes, IQR = 3.4-5.9 minutes; p = 0.044). CONCLUSIONS: There was no difference in teaching the skills of image acquisition and interpretation to novice FAST examiners using the multimedia simulator or normal human models. These data suggest that practical image acquisition skills learned during simulated training can be directly applied to human models.

Punch injuries: insights into intentional closed fist injuries.

OBJECTIVES: This study sought to investigate the patterns of injury resulting from a punch mechanism and to investigate the associated psychopathology present in patients with these injuries. METHODS: Retrospective analysis of patients with hand radiographs ordered from the emergency department allowed for identification of patients with a punch mechanism. We recorded injury patterns and queried patients' medical records for associated psychopathology. RESULTS: 1,292 patients underwent hand radiographs during a one-year time period; 172 patients (13%) were radiographed following an intentional punch injury, identifying 76 fractures in 70 patients. Males contributed a greater proportion of patients presenting with punch injury when compared to females (80% vs. 20%). Males were more likely to sustain fracture from a punch mechanism (48% vs. 11%, OR 7 [95% CI 2.3-20.9]), but were less likely to have preexisting documented psychiatric disease (23% vs. 49%, OR 3.1 [95% CI 1.4-6.7]). Of all fractures, 61% were to the fifth metacarpal, 21% were to the remainder of the metacarpals, and the remaining were fractures to phalanges and bones of the wrist. CONCLUSION: Women are less likely to present with punch injury and are less likely to sustain a fracture when they do present but have more associated psychiatric disease. Both men and women presenting with punch injuries have a higher prevalence of psychiatric disease than the background incidence in the population as a whole. Although punch injuries result in a significant number of boxer fractures, a number of other injuries are associated with punch mechanisms.

Resident productivity: trends over consecutive shifts.

BACKGROUND: It has been shown that residents' ability to see more patients and patients of higher acuity improves with level of training. AIMS: No published study has reviewed whether residents become less productive with consecutive shifts. Determining peak resident productivity can optimize staffing to manage patient flow and enhance resident exposure to patients, which is critical to their education. We examine the relationship between resident productivity and number of consecutive shifts worked. METHODS: This is a retrospective review of emergency medicine (EM) resident productivity defined as patients evaluated per hour per shift. Data were collected utilizing patient tracker software which provides a record of physician assignment and checked against the computerized medical record. Residents were credited with a patient if they initiated the workup and dictated the chart. Productivity was tallied for 188 first-year shift strings, 303 second-year shift strings, and 224 third-year shift strings beginning 1 November 2006. Analysis of variance (ANOVA) was used to assess for productivity differences based on the shift number, with the first shift in a series being designated "1," the second consecutive shift being designated "2," and so on. RESULTS: First-year residents saw 0.82, 0.81, and 0.91 patients per hour on consecutive shifts (F((2,175))=2.89, p = 0.06), second-year residents saw 1.12, 1.08, 1.17, and 1.28 patients per hour on consecutive shifts (F((3,292))=4.19, p = 0.006), and third-year residents saw 1.19, 1.24, and 1.33 patients per hour on consecutive shifts (F((2,211))=4.08, p = 0.02). CONCLUSIONS: Instead of tiring, residents maintain or improve productivity over consecutive shifts.
