An integrated ultrasound curriculum (iUSC) for medical students: 4-year experience

Medical students' knowledge towards ultrasound in Kurdistan region, Iraq: a cross-sectional study

POCUS has become an indispensable modality in clinical practice due to its real-time, non-invasive imaging and accessibility. On the contrary, despite the importance of ultrasound, training is significantly variable across medical education, thereby leaving gaps in competency among graduates. In light of the aforementioned fact, ultrasound training is increasingly part of medical curricula; however, practical exposure remains limited due to logistic barriers. This cross-sectional study assesses ultrasound knowledge among 213 medical students across six academic years in the Kurdistan Region of Iraq. Results show that 95.3% of the students know that ultrasound is applied outside obstetrics, hence showing a general comprehension of its area. However, 43.7% of students wrongly believe that exposure to ultrasound radiation is involved, whereas only 56.8% appropriately recognize clinical contraindications, identifying residual misunderstandings. Knowledge improved with advancing year of study. For instance, knowledge that ultrasound is non-radiative increased from 17.6% in students in their first year to 95% in those in the sixth year (p < 0.001). Similarly, the use of ultrasound gel is known to 54.1% of the students in the first year, with this number increasing to 100% in the sixth year of study (p < 0.001). The overall ratings of students' knowledge were: fair, 86.4%; good, 8.5%; and poor, 5.2%. These results also indicate that more comprehensive ultrasound education in terms of ensuring proficiency is necessary, and misconceptions have to be dispelled among future physicians. This study is the first study which conducted in Kurdistan region of Iraq, therefore we think that it is important to know the medical students then the medical education program related to sonography can be changed according to the result.

The assessment of point-of-care ultrasound (POCUS) in residency: the benefits of a four-year longitudinally integrated curriculum

CONTEXT

Point-of-care ultrasound (POCUS) has diverse applications across various clinical specialties, serving as an adjunct to clinical findings and as a tool for increasing the quality of patient care. Owing to its multifunctionality, a growing number of medical schools are increasingly incorporating POCUS training into their curriculum, some offering hands-on training during the first 2 years of didactics and others utilizing a longitudinal exposure model integrated into all 4 years of medical school education. Midwestern University Arizona College of Osteopathic Medicine (MWU-AZCOM) adopted a 4-year longitudinal approach to include POCUS education in 2017. There is a small body of published research supporting this educational model, but there is not much data regarding how this approach with ultrasound curriculum translates to real-world changes in POCUS use by graduate student clinicians having received this model of education.

OBJECTIVES

The objectives of this study are to determine the frequency of POCUS use by MWU-AZCOM graduates and to assess how a 4-year longitudinal ultrasound curriculum may enhance the abilities of MWU-AZCOM graduates to perform and interpret ultrasound imaging in specific residency programs.

METHODS

The study was approved by the MWU Institutional Review Board (#IRBAZ-5169, approval date October 3, 2022). An anonymous novel 12-question survey was conducted utilizing Research Electronic Data Capture (REDCap), a secure online platform, and distributed to MWU-AZCOM 2021 and 2022 graduates via email. Survey questions were aimed at assessing frequency of use, utilization of different imaging modalities, reasons for utilizing POCUS, barriers/enablers to utilizing POCUS, ultrasound training, and confidence in performing scans and interpreting POCUS imaging. All of the 104 surveys returned were included in the study. Statistical software R version 4.3 was utilized to conduct statistical analyses.

RESULTS

Of the 484 surveys distributed, 104 were completed (21.5 % response rate). Responses came from residents working in 14 different specialties, 50 in primary care and 54 in nonprimary care. Of all respondents, 85.6 % currently utilize POCUS in their practice on at least a monthly basis and 77.0 % believe that their POCUS training in medical school enriches their current practice in residency. The top five modalities utilized by residents were procedures (89.9 %), cardiac (88.8 %), pulmonary (82.0 %), Focused Assessment with Sonography for Trauma (FAST, 73.0 %), and vascular (71.9 %). Respondents recognized POCUS as a beneficial diagnostic tool (97.8 %) and reported enhancements in physical examination skills (58.4 %) and professional growth (61.8 %). Facilitators for POCUS adoption included cost-effectiveness (82.0 %), diagnostic differentiation (78.7 %), and safety (79.8 %). Barriers included a lack of trained faculty (27.9 %), absence of necessary equipment (26.9 %), and cost of equipment (22.1 %). Participants demonstrated high confidence levels in performing (74.0 %) and interpreting (76.0 %) POCUS, with 43.3 % believing that their POCUS training enhanced their attractiveness as residency candidates.

CONCLUSIONS

This study supports the positive impact of a 4-year longitudinal POCUS curriculum on graduates' practice. It emphasizes the link between MWU-AZCOM's curriculum and real-world clinical needs. Addressing identified barriers and advancing hands-on training can further enhance POCUS understanding, ensuring that future physicians are well-prepared to leverage its diagnostic potential across medical specialties.

Impact and reception of point-of-care ultrasound training across medical education levels

BACKGROUND

Point-of-care ultrasound (POCUS) is a versatile and cost-effective technology that can significantly enhance medical education and clinical practice. This study examines the acceptance of POCUS among medical students and explores strategies to optimize its integration into their training.

MATERIALS AND METHODS

A total of 318 medical students, spanning both preclinical and clinical semesters, participated in seminars that included POCUS demonstrations and hands-on practice. Their perceptions were assessed through a voluntary questionnaire based on the Technology Acceptance Model (TAM), which furthermore explored the ideal timing and potentially suitable subjects for integrating POCUS into the curriculum, with an emphasis on its role in developing clinical skills and supporting decision-making.

RESULTS

Among preclinical students, 60.7% had no prior ultrasound exposure, while 97% of clinical students reported some experience, albeit often limited. Despite the majority of senior students having some ultrasound experience, many lacked confidence in its use. Confidence in sonography skills was generally low across both groups, with 95.9% of preclinical and 79.4% of clinical students expressing a lack of confidence. Importantly, both preclinical and clinical students recognized the high usefulness of POCUS skills and rated the technology as user-friendly, with clinical students perceiving it as slightly easier to use. When asked to identify the most suitable subjects for POCUS training, students most frequently cited anatomy (35.2%) and internal medicine (16.7%). Additionally, a majority of students (57.7%) advocated for POCUS education to begin as early as the first semester.

CONCLUSION

This study highlights a significant gap in ultrasound training among medical students, while also underscoring their strong motivation to learn and their positive perception of POCUS as a valuable tool for enhancing clinical skills and decision-making. The findings emphasize that early integration of sonography into the medical curriculum is both highly desired by students and essential for advancing medical education. This is particularly timely and important given the growing role of artificial intelligence in ultrasound technology and the opportunities expected to emerge from this integration.

Integration of point of care ultrasound into undergraduate medical education at Texas Tech University Health Sciences Center school of medicine: a 6 year review

BACKGROUND

Point-of-care ultrasound (POCUS) education has become an essential component of medical school curricula. Ultrasound represents a highly effective teaching modality to reinforce anatomical knowledge gained during cadaveric dissections. At Texas Tech University Health Sciences Center-School of Medicine (TTUHSC-SOM), POCUS was incorporated into the pre-clerkship curriculum especially during the first year of medical school anatomy course.

METHODS

Pre- and post-ultrasound quizzes and summative exam performance were used to evaluate ultrasound session effectiveness. Post-block survey results were utilized to assess students' perception of these sessions.

RESULTS

A significant increase in post-quiz scores compared to pre-quiz scores (p < 0.0001) was observed in all three ultrasound sessions. Students ranked the overall experience with ultrasound sessions highly with 86% indicating ultrasound training was valuable in understanding human anatomy. Additionally, 92% indicated being more at ease in acquiring ultrasound images as the block progressed.

CONCLUSIONS

First-year medical students perceived ultrasound training as valuable in enhancing their understanding of human anatomy and became more proficient acquiring ultrasound images as the block progressed. Early introduction of POCUS in the pre-clerkship curriculum helps build foundational knowledge and skills that support students in developing competency in image acquisition and interpretation.

Current status of ultrasound training in obstetrics and gynecology: a scoping literature review

Introduction

As a widely accessible, cost-effective, and safe imaging tool, obstetric and gynecologic (OB/GYN) ultrasound (ULS) plays a vital role in diagnostics and patient care. With its growing relevance, the demand for comprehensive education in this field increases. The objective of this work was to outline the current state of OB/GYN ULS education.

Methods

A scoping literature search was performed until May 2023 using the medical database PubMed according to PRISMA guidelines. Using specific keywords, relevant publications were filtered. Subsequently, abstracts were independently reviewed by two authors and the inclusion of each publication was assessed against pre-defined key search terms. Full-text versions of the included publications were scrutinized and pertinent information was extracted.

Results

In this review, 126 articles from the literature search matched the inclusion criteria and were investigated. Our findings revealed a diverse range of course concepts and programs, a lot of them not meeting the expectations of trainees and international guidelines. OB/GYN ULS training primarily targets residents, yet opportunities for early exposure and continuing education are underexplored. International organizations, such as the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) and the German Society for Ultrasound in Medicine (DEGUM) have proposed guidelines and curricula for standardized training. However, adoption remains varied. There is an emergent need to innovate teaching methods.

Conclusion

There is consensus that standardizing OB/GYN ULS curricula could enhance training quality and streamline the creation of new programs, ultimately improving patient care. Further research is needed to define the most effective strategies for curriculum development and implementation.

A Role for Clinical Anatomists in Ultrasound Education

More educators are needed to deliver comprehensive ultrasound training across the medical education spectrum. Regardless of prior clinical experience level, all new ultrasound learners need to begin their education by gaining the same foundational ultrasound knowledge, skills, and abilities. Ultrasound-trained clinical anatomists are well positioned to teach basic image acquisition and fundamental skills and knowledge. Learners can then progress to more advanced training and clinical integration concepts with ultrasound-trained clinician educators. Institutions looking to start or expand ultrasound training programs should include support for the development of ultrasound skills in any willing clinical anatomists affiliated with their organizations.

Two-week intensive medical student point-of-care ultrasound training impact on long term utilization

BACKGROUND

There is little to no data evaluating long term usage of point of care ultrasound (POCUS) after a training intervention for medical students. The purpose of this study was to examine the impact of an intensive POCUS training program on medical student's usage at 9-months post-program.

METHODS

This was a prospective cross-sectional study of rising second year medical students who participated in a 2-week summer POCUS training program. Instruction consisted of 8 h of asynchronous online didactic material, 2-4 h of daily hands-on instructor-led and independent scanning, and instruction on how to teach POCUS. Students were assessed pre- and post-program, and again at 9 months post-program to evaluate POCUS usage.

RESULTS

A total of 56 students participated in the program over 2 summers; 52 (92.9%) responded to the 9-month post-program survey. At 9 months, 49 (94.2%) of students taught POCUS after the program to peers or faculty. Students reported serving as a POCUS instructor in 283 subsequent teaching sessions accounting for 849 h of POCUS instruction time. Six (11.5%) students were involved in the creation of a POCUS interest group on their regional campus, 7 (13%) created a POCUS curriculum for their student interest group, and 4 (7.7%) created an opt-in co-curricular POCUS program for students at their regional campus. Three (5.8%) students did not serve as educators after the program and only one student reported not using POCUS again after the program.

CONCLUSION

After a 2-week intensive POCUS training program for medical students, the majority of students demonstrated continued involvement in POCUS learning and education at 9-month follow-up including serving as peer instructors and assisting with limitations in financial resources and trained faculty.

Student ultrasound education - current views and controversies

As an extension of the clinical examination and as a diagnostic and problem-solving tool, ultrasound has become an established technique for clinicians. A prerequisite for high-quality clinical ultrasound practice is adequate student ultrasound training. In light of the considerable heterogeneity of ultrasound curricula in medical studies worldwide, this review presents basic principles of modern medical student ultrasound education and advocates for the establishment of an ultrasound core curriculum embedded both horizontally and vertically in medical studies.

Evaluation of a Self-Driven Large Animal Point of Care Ultrasound Learning Program for Veterinary Students

Point of care ultrasound (POCUS) has the potential to improve health care outcomes and is increasingly used in veterinary primary care and specialty practice. The aim of this study was to evaluate a self-driven POCUS learning program during clinical rotations in a large animal teaching hospital. A randomized controlled trial of 94 students evaluated the hypotheses that access to a self-driven POCUS program would improve scores on a written test and the quality of subjective, objective, assessment and plan (SOAP) documents. Use of the POCUS devices and perceptions of veterinary students toward POCUS were analyzed. The self-driven POCUS learning program was feasible, and the perception of most students (94%) was that the program was useful for their education. Access to equipment, ability to scan individually, the hands-on learning aspect, and clinicians' help were the most valued aspects of the program. Earlier access to POCUS in the curriculum, hands-on tutorials/labs, and a more structured learning program were identified by students as aspects to improve. Access to the self-driven POCUS program resulted in significantly higher scores on the written test in a subpopulation of students with lower scores. No significant differences in results on the multiple-choice tests in the subpopulation with higher scores or in SOAP scores of the complete group or subpopulations were found. A self-driven POCUS learning program was perceived as beneficial by students, increased POCUS knowledge in students with lower test scores, and was possible to implement in a busy large animal teaching hospital.

Ultrasound Incorporation in Gross Anatomy Labs in a Master of Medical Sciences Program: A Mixed-Methods Analysis of Student Performance and Perception

OBJECTIVES

Teaching ultrasound imaging is on the rise in undergraduate medical anatomy education. However, there is little research exploring the use of ultrasound in preparatory graduate programs. The purpose of this study is to identify the effects of ultrasound imaging inclusion in a graduate gross anatomy course.

METHODS

Master of Medical Sciences students were enrolled in a prosection-based anatomy course that included pinned cadaver stations and an ultrasound station. Using ultrasound, teaching assistants imaged volunteers demonstrating anatomical structures students previously learned at cadaver stations. Students answered one ultrasound image question on each practical exam and were asked to participate in a pre- and post-course survey. Student practical and lecture exam scores and final course grades from the 2022 cohort were compared to a historical control cohort from 2021 via statistical analysis, including a survey administered to the 2022 cohort.

RESULTS

Two hundred students from the 2021 cohort and 164 students from the 2022 cohort participated in this study. Students in the 2022 cohort had significantly higher scores in 1 of the 5 practical exams (P < .05, d = .289), and 2 of the 5 written exams (P < .05, d = .207), (P < .05, d = .311). Survey data revealed increased (P < .05, d = 1.203) learning outcome achievement from pre-survey to post-survey in the intervention cohort. Students who correctly answered the ultrasound question performed significantly better on practical's 3 (P < .05) and 4 (P < .05) than those who missed the ultrasound question.

CONCLUSIONS

These findings suggest that ultrasound imaging in a cadaver lab is beneficial to graduate students' learning and understanding of gross anatomy.

Point-of-Care Ultrasound training in undergraduate education in the European Union: current situation and perspectives

BACKGROUND

Given the widespread use of Point-of-Care UltraSound (PoCUS) in clinical practice, with ultrasound machines becoming more portable and affordable, recommendations and position statements from ultrasound societies now promote teaching PoCUS in the undergraduate curriculum. Nevertheless, surveys about PoCUS teaching in European medical schools are lacking. This survey aims to overview the current and future undergraduate PoCUS courses in the European Union (EU).

RESULTS

A questionnaire was sent to medical schools in 26 of the 27 countries of the EU; Luxembourg is the only country without a medical school. The survey was completed by the dean or a member of the medical school with knowledge of the medical curriculum. Of the 58 medical schools from 19 countries that responded to the survey, 18 (31.0%) from 13 (68.4%) EU countries reported the existence of an undergraduate PoCUS curriculum and a further 16 (27.6%) from 12 (41.4%) EU countries intended to offer it in the future. No significant difference was observed between the current and future PoCUS curricula regarding its content and purpose. Less than 40 h of theoretical teaching is provided in all the medical schools and less than 40 h of practical training is provided in 12 (75%) of the 16 medical schools which answered this specific question. Of the 40 (69%) surveyed medical schools that do not currently teach PoCUS, 20 (50%) intend to offer PoCUS courses in the future.

CONCLUSION

Although the lack of teaching hours in curricula suggests that most PoCUS courses are introductory in nature and that medical students are possibly not trained to become autonomous in clinical practice, evaluating the feasibility and impact of PoCUS teaching on clinical practice should be promoted. The medical schools that intend to develop this curriculum should be encouraged to implement validated tools to objectively assess their programs and students' performances.

Bedside Ultrasound to Identify and Predict Severity of Dysphagia Following Ischemic Stroke: Human Versus Artificial Intelligence

OBJECTIVE

Dysphagia is a significant ischemic stroke complication that can lead to aspiration. Identification of at-risk patients can be logistically difficult and costly. Researchers investigated whether quantitative ultrasound assessment of hyoid bone movement during induced swallowing would predict failure of videofluoroscopy (VFS) or fiberoptic endoscopic evaluation of swallowing (FEES), as determined by a penetration-aspiration scale (PAS) score. Additionally, ability of a machine learning (ML) algorithm to predict PAS success or failure from real-time ultrasound video recordings was assessed.

METHODS

A prospective, single-blinded, observational pilot study was conducted from June 2019 through March 2020 at a comprehensive stroke center on a convenience sample of patients admitted with diagnosis of acute ischemic stroke undergoing VFS or FEES as part of dysphagia assessment. Researchers performed a midsagittal airway ultrasound during swallowing in patients receiving an objective swallowing assessment by speech language pathologists who were blinded to ultrasound results. Sonologists measured hyoid bone movement, and researchers then constructed an ML algorithm designed for real-time video analysis using a long short-term memory network with an embedded VGG16 convolutional neural network.

RESULTS

Videos from 69 patients were obtained with their respective PAS results. In total, 90% of available videos were used for algorithm training. After training, the ML algorithm was challenged with the 10% previously unseen videos and then compared with PAS outcomes. Statistical analysis included logistic regression and correlation matrix testing on human ultrasound measurements. Cohen's κ was calculated to compare deep learning algorithm prediction with PAS results. Measurement of hyoid bone elevation, forward displacement, total displacement and mandible length was unable to predict PAS assessment outcome (p values = 0.36, 0.13, 0.11 and 0.32, respectively). The ML algorithm showed substantial agreement with PAS testing results for predicting test outcome (κ = 0.79; 95% confidence interval: 0.52-1.0) CONCLUSION: Manual ultrasound measurement of hyoid movement during swallowing in stroke patients failed to predict PAS swallowing results. However, an ML algorithm showed substantial agreement with PAS results despite a small data set, which could greatly improve access to dysphagia assessment in the future.

Past and Present of Point-of-Care Ultrasound (PoCUS): A Narrative Review

This article aims to conduct a literature review to gain insight into point-of-care ultrasound (PoCUS). PoCUS is a rapid, accurate, non-invasive, and radiation-free imaging modality that can be used in stable and unstable patients. PoCUS can be performed parallel to physical examination, resuscitation, and stabilization; repeated exams in critical patients are essential for improving sensitivity. The review highlights how PoCUS, which was initially used to detect free intraperitoneal fluid in trauma patients, has developed into a life-saving diagnostic tool that could be utilized by treating physicians during various stages of diagnosis, resuscitation, operation, and postoperative critical care when managing sick patients. The review also notes the barriers to the widespread uptake of PoCUS in general internal medicine and the recent commercial availability of "pocket" or handheld probes that have made PoCUS more readily available. This review concludes that adopting a focused binary decision-making approach can maximize PoCUS's value in many clinical settings, including emergency departments, intensive care units, and operation theatres. Overall, the review emphasizes the importance of awareness of common indications, limitations, and strengths of this evolving and promising technology to determine its future trajectory: Providing comprehensive PoCUS training within internal medicine curriculums and supporting trainers to do so.

Development of a novel observed structured clinical exam to assess clinical ultrasound proficiency in undergraduate medical education

OBJECTIVES

A pilot study was performed to develop and test an observed structured clinical exam (OSCE) for clinical ultrasound in second-year medical students. The goal was to assess a longitudinal clinical ultrasound curriculum for medical students and to help determine readiness to perform ultrasound during clinical clerkships.

METHODS

The OSCE contained 40 tasks over 30 min in a one-to-one examiner to examinee environment using standardized patients covering cardiac, pulmonary, and inferior vena cava (IVC) ultrasound exams along with 6 critical diagnoses. Examinees were assessed using a binary checklist approach. A two-way ANOVA analysis was performed to determine if there were differences between the day and session the OSCE was administered. Results are presented as mean ± standard deviation.

RESULTS

One hundred fifty-two students were tested with an overall mean score of 64.9 ± 17.6%. Scores between the cardiac, IVC, and lung sections varied-67.8% ± 18.8%, 62.4% ± 26.2%, and 57.1% ± 20.6%, respectively. One hundred twenty-six (82.9%) answered at least one critical diagnosis incorrectly. Students in the late session performed better than the early session (1: 60% vs 2: 69%, p = .001).

CONCLUSIONS

Students performed better in later sessions. Additionally, the number of questions left blank at the end of the exam suggests that the length of the OSCE should be evaluated. Incorporating critical diagnoses was challenging for examinees. The proposed OSCE is a valuable assessment tool that could be adapted to assess student's readiness to use clinical ultrasound prior to clerkships.

Point-of-Care Ultrasound and Procedural Instruction in the Family Medicine Clerkship: A CERA Study

BACKGROUND AND OBJECTIVES

Point-of-care ultrasound (POCUS) education has become a mainstay in resident education in multiple specialties, including family medicine (FM), but literature regarding the use of POCUS during clinical medical student education is lacking. The purpose of this study was to investigate whether and how POCUS education is conducted in FM clerkships in the United States and Canada and how it compares to more traditional FM clinical procedural instruction.

METHODS

As part of the 2020 Council of Academic Family Medicine's Educational Research Alliance survey of FM clerkship directors, we surveyed clerkship directors in the United States and Canada about whether and how POCUS education, as well as other procedural instruction in their institutions and FM clerkships, was conducted. We included questions regarding POCUS and other procedural use by preceptors and faculty.

RESULTS

We found that 13.9% of clerkship directors reported structured POCUS education during clerkship, while 50.5% included other procedural training. The survey revealed that 65% of clerkship directors felt that POCUS was an important component of FM, but this was not a predictor of POCUS use in personal or preceptor practice nor of its inclusion in FM clerkship education.

CONCLUSIONS

Structured POCUS education is a rare component of FM clerkship education; while more than half of clerkship directors felt that POCUS was important for FM, few used it personally or included it in clerkship education. As POCUS continues to be integrated into medical education in FM, the clerkship may represent an opportunity to expand POCUS exposure for students.

Ultrasound Education in an Elective Course in the Undergraduate Medical Curriculum Improves Students' Subjective Learning and Clinical Rotation and Residency Preparedness

Objectives

Studies have demonstrated that students are able to improve their understanding of anatomy, physical exam skills, and clinical knowledge when ultrasound is incorporated into their education. This study investigates whether students enrolled in an elective with significant use of ultrasound (ACS) in their preclinical years subjectively improved their preparedness for clinical rotations, residency, and learning in several subjects.

Methods

This was a retrospective analysis of an anonymous online needs assessment survey sent to 384 third- and fourth-year medical students. Survey items included Likert scales analyzed with a student's t-test or Chi-Square analysis and yes/no questions analyzed with Chi square, as well as demographic information.

Results

201 students responded to the survey (52.3% response rate). ACS participants reported feeling more prepared for their clinical rotations than their non-ACS peers (3.5 vs. 2.33, p < 0.001 ) and felt more prepared for residency (3.12 vs 1.91, p < 0.001). ACS students also found ultrasound significantly more helpful in understanding the physical exam (69.3% vs. 53.2%, p = 0.02) and anatomy (94.7% vs. 81%, p = 0.012).

Conclusions

Student respondents expressed a desire for more ultrasound education throughout medical school. Students who participated in ACS reported feeling more prepared for their clinical rotations and residency than their non-ACS peers and were more likely to feel that ultrasound improved their understanding of anatomy and the physical exam. This study adds to the literature suggesting that increasing the quantity of ultrasound in preclinical medical education may improve students' satisfaction, learning and clinical preparedness.

Incorporating ultrasound training into undergraduate medical education in a faculty-limited setting

BACKGROUND

Point of care ultrasound (POCUS) is becoming a major extension of patient care. From diagnostic efficacy to its widespread accessibility, POCUS has expanded beyond emergency departments to be a tool utilized by many specialties. With the expansion of its use, medical education has begun to implement ultrasound education earlier in curricula. However, at institutions without a formal ultrasound fellowship or curriculum, these students lack the fundamental knowledge of ultrasound. At our institution, we set out to incorporate an ultrasound curriculum, into undergraduate medical education utilizing a single faculty member and minimal curricular time.

METHODS

Our stepwise implementation began with the development of a 3-hour fourth-year (M4) Emergency Medicine clerkship ultrasound teaching session, which included pre- and post-tests as well as a survey. The success with this session progressed to the development of a designated fourth-year ultrasound elective, which was evaluated with narrative feedback. Finally, we developed six 1-hour ultrasound sessions that correlated with first-year (M1) gross anatomy and physiology. A single faculty member was responsible for this curriculum and other instructors included residents, M4 students, and second-year (M2) near-peer tutors. These sessions also included pre- and post-tests and a survey. Due to curricular time limitations, all but the M4 Emergency Medicine clerkship session were optional.

RESULTS

87 students participated in the emergency medicine clerkship ultrasound session and 166 M1 students participated in the voluntary anatomy and physiology ultrasound sessions. All participants agreed or strongly agreed that they would like more ultrasound training, that ultrasound training should be integrated into all four years of undergraduate medical education. Students were in strong agreement that the ultrasound sessions helped increase understanding of anatomy and anatomical identification with ultrasound.

CONCLUSION

We describe the stepwise addition of ultrasound into the undergraduate medical education curriculum of an institution with limited faculty and curricular time.

Enhanced point of care ultrasound skills after additional instruction from simulated patients

Background

Point of Care Ultrasound (POCUS) training in Canadian undergraduate medical programs is steadily increasing. To date, the simulated patients (SPs) in our program have only provided feedback on comfort and professionalism. Involving the POCUS SPs as teachers (SP-teachers) of POCUS skills provides an additional opportunity for instruction. In this pilot study, we explored the impact of SP-teachers instructing medical trainees while they learned POCUS. Outcomes of interest included the level of proficiency achieved after the session and trainee satisfaction with the learning experience.

Methods

Second year medical students were randomized into a conventional or SP-teacher learning experience. Both groups received the same video tutorial, instructor guidance, and basic SP feedback (comfort and professionalism). The SP-teaching group received additional instruction (landmarks, transducer technique, and troubleshooting) from the SP-teachers when session instructors were assisting others. Students evaluated the session and were subsequently assessed through direct observation.

Results

Students that received SP-teaching scored significantly higher in both image acquisition (p = 0.029, d = 1.26) and overall entrustment (p = 0.002, d =1.75). Both groups rated their sessions highly.

Conclusions

Students that received SP-teaching were observed to better acquire images and achieved higher entrustment scores. In this pilot study, SP-teachers had a positive effect on acquisition of POCUS skills.

Open-Source Ultrasound Trainer for Healthcare Professionals: A Pilot Randomized Control Trial

INTRODUCTION

This technical report describes the development of a high-fidelity, open-source ultrasound trainer and showcases its abilities through a proof-of-concept, pilot randomized control trial. The open-source ultrasound trainer (OSUT) aims to enhance anatomical visualization during ultrasound education. The OSUT can attach to any ultrasound transducer, uses minimal hardware, and is able to be used during live patient ultrasound examinations.

METHODS

After viewing a standardized training video lecture, 24 incoming first-year medical students with no prior ultrasound experience were randomized into a control group given an ultrasound system or an intervention group given the OSUT in addition to an ultrasound system. Both groups were tasked with localizing the thyroid, abdominal aorta, and right kidney on a patient. Performance outcomes were structure localization time, ultrasound image accuracy, and preactivity and postactivity participant confidence.

RESULTS

The OSUT decreased right kidney localization time (Kruskal-Wallis, P < 0.001), increased sonographer right kidney accuracy ratings (Mann-Whitney U , U = 10.5, P < 0.05), and increased confidence in structure identification (Mann-Whitney U , U = 37, P = 0.045) and overall ultrasound ability (Wilcoxon signed-rank test, P = 0.007). There was no significant change in localization time, accuracy ratings, or participant confidence for locating the thyroid and abdominal aorta.

CONCLUSIONS

A high-fidelity, open-source ultrasound trainer was developed to aid healthcare professionals in learning diagnostic ultrasound. The study demonstrated the potential beneficial effects of the OSUT in localizing the right kidney, showcasing its adaptability and accessibility for ultrasound education for certain anatomical structures.

EFSUMB Clinical Practice Guidelines for Point-of-Care Ultrasound: Part One (Common Heart and Pulmonary Applications) SHORT VERSION

OBJECTIVE

 To evaluate the evidence and produce a summary and recommendations for the most common heart and lung point-of-care ultrasound (PoCUS).

METHODS

 We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS. Following review of the evidence, a summary and recommendations were produced, including assigning levels of evidence (LoE) and grading of recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75 % was required to progress to the next section. The ERG then reviewed and indicated their level of agreement of the summary and recommendation for each question (using a 5-point Likert scale), which was approved in the case of a level of agreement of greater than 75 %. A level of agreement was defined as a summary of "strongly agree" and "agree" on the Likert scale responses.

FINDINGS AND RECOMMENDATIONS

 One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1), the remaining 9 questions achieved broad agreement with an assigned LoE of 4 and a weak GRADE recommendation (question 2), three achieved an LoE of 3 with a weak GRADE recommendation (questions 3-5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6-8) and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10).

CONCLUSION

 These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

FoCUS cardiac ultrasound training for undergraduates based on current national guidelines: a prospective, controlled, single-center study on transferability

INTRODUCTION

In emergency and critical-care medicine, focused cardiac ultrasound (FoCUS) is indispensable for assessing a patient's cardiac status. The aim of this study was to establish and validate a peer-to-peer-supported ultrasound course for learning FoCUS-specific skills during undergraduate studies at a German university.

METHODS

A 1-day, 12 teaching units training course was developed for students in the clinical section of medical college, with content based on the current national guidelines. A total of 217 students participated in the study (97 in the course group and 120 in the control group). The course and the participants' subjective assessment of improved skills were evaluated using a questionnaire (7-point Likert scale; 7 = complete agreement and 1 = no agreement at all). Objective learning gains were assessed by tests before and after the course. These consisted of a test of figural intelligence (eight items) and a test of technical knowledge (13 items).

RESULTS

The course participants experienced significant improvement (P < 0.001) from before to after the course, with a large effect size of η²_part = 0.26. In addition, the course group had significantly better results (P < 0.001) than the control group in the post-test, with a medium to large effect size of η²_part = 0.14. No significant differences (P = 0.27) were detected in the test section on figural intelligence. The evaluations showed that the participants had a high degree of satisfaction with the course approach, teaching materials, and tutors. There was also a positive increase in their subjective assessment of their own skills, including areas such as technical knowledge, ultrasound anatomy, and performance of the examination.

CONCLUSION

The results of both the objective learning assessment and the subjective evaluations suggest that a FoCUS course originally intended for qualified physicians is equally suitable for students. With the development and provision of modern digital teaching media, even more students will be able to benefit from this approach in the future.

EFSUMB Clinical Practice Guidelines for Point-of-Care Ultrasound: Part One (Common Heart and Pulmonary Applications) LONG VERSION

AIMS

 To evaluate the evidence and produce a summary and recommendations for the most common heart and lung applications of point-of-care ultrasound (PoCUS).

METHODS

 We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS. Following review of the evidence, a summary and recommendation were produced, including assignment of levels of evidence (LoE) and grading of the recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75 % was required to progress to the next section. The ERG then reviewed and indicated their level of agreement regarding the summary and recommendation for each question (using a 5-point Likert scale), which was approved if a level of agreement of greater than 75 % was reached. A level of agreement was defined as a summary of "strongly agree" and "agree" on the Likert scale responses.

FINDINGS AND RECOMMENDATIONS

 One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1). The remaining 9 questions achieved broad agreement with one assigned an LoE of 4 and weak GRADE recommendation (question 2), three achieving an LoE of 3 with a weak GRADE recommendation (questions 3-5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6-8), and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10).

CONCLUSION

 These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

The assessment of point-of-care-ultrasound (POCUS) in acute care settings is benefitted by early medical school integration and fellowship training

CONTEXT

Point-of-care ultrasound (POCUS) has widespread utilization in multiple clinical settings. It has been shown to positively influence clinician confidence in diagnosis and can help appropriately manage patients in acute care settings. There has been a growing trend of increased emphasis on incorporating POCUS training in the first 2 years of the medical school curriculum.

OBJECTIVES

This article aims to analyze the clinical use of POCUS in acute settings and how training early in medical school may strengthen clinician confidence and utilization.

METHODS

An anonymous 10-question survey on POCUS use was conducted via a secure online platform and distributed to board-certified practicing physicians (MDs and DOs) with educational agreements with Midwestern University (MWU) across acute care specialties. This included preceptors within the MWU graduate medical education clinical consortium. Survey questions were aimed at assessing frequency of use, machine type, reasons for utilizing POCUS, initial ultrasound training, confidence in performing/interpreting POCUS, and perceived impact on patient outcomes. Surveys less than 50% complete were excluded. All surveys returned were more than 50% complete and thus included in the study. Statistical analyses were conducted utilizing the statistical software R version 4.0.

RESULTS

Surveys were sent out to 187 participants with 68 responses (36.4% response rate). The survey results demonstrated a relationship between learning POCUS earlier in one's medical career (medical school, residency, or fellowship) to increased use in acute settings when compared to learning POCUS during clinical practice. Of the 68 respondents, 65 (95.6%) indicated that they agree or strongly agree that POCUS use improves patient care, and 64 (94.1%) indicated that they agree or strongly agree that the use of POCUS can improve patient outcomes.

CONCLUSIONS

Our survey of acute care physicians indicated that most respondents utilize POCUS daily or weekly (90.8%), and this was related to fewer years of practice (under 10 years from medical school graduation, 94.6%). Moreover, POCUS was utilized primarily in acute care settings for procedures (25%, n=17/68 respondents). These survey results indicate that early integration of POCUS education in osteopathic medical school curricula and throughout fellowship training could likely enhance POCUS utilization in acute care settings.

The ultrasound use of simulators, current view, and perspectives: Requirements and technical aspects (WFUMB state of the art paper)

Simulation has been shown to improve clinical learning outcomes, speed up the learning process and improve learner confidence, whilst initially taking pressure off busy clinical lists. The World Federation for Ultrasound in Medicine and Biology (WFUMB) state of the art paper on the use of simulators in ultrasound education introduces ultrasound simulation, its advantages and challenges. It describes different simulator types, including low and high-fidelity simulators, the requirements and technical aspects of simulators, followed by the clinical applications of ultrasound simulation. The paper discusses the role of ultrasound simulation in ultrasound clinical training, referencing established literature. Requirements for successful ultrasound simulation acceptance into educational structures are explored. Despite being in its infancy, ultrasound simulation already offers a wide range of training opportunities and likely holds the key to a broader point of care ultrasound education for medical students, practicing doctors, and other health care professionals. Despite the drawbacks of simulation, there are also many advantages, which are expanding rapidly as the technology evolves.

Development and implementation of a comprehensive ultrasound curriculum for medical students: The Bonn internship point-of-care-ultrasound curriculum (BI-POCUS)

Background

Point-of-care ultrasound (POCUS) is rapidly gaining ground within different areas of applications. Despite the high and increasing relevance of ultrasound, the availability of structured training programs in medical schools is still limited. Therefore, many doctors keep acquiring all their ultrasound skills throughout their postgraduate training. As a result, new residents lack theoretical and practical ultrasound abilities that are critical in everyday clinical practice. In order to improve this, we created and implemented a complete ultrasound curriculum for all medical students throughout their internship year that focuses on hands-on abilities in ultrasound imaging.

Methods

We used Kern's six-step model of curricular development comprising (1) problem identification and general needs assessment, (2) needs assessment of the targeted learners, (3) goals and objectives, (4) educational strategies, (5) implementation, and (6) evaluation and feedback by board-certified ultrasound experts. A two rounds Delphi process with multilevel, self-completed questionnaires and individual using a 9-point Likert scale and free text comments was used to identify learning objectives and reach agreement on the content of the curriculum.

Results

The curriculum developed is aimed at students with no or little experience in their internship year and will be taught as part of their weekly-based internship training courses consisting of 2 hours of theory and 3 hours of practical training. The training will be conducted within a modular framework focusing on the key requirements of POCUS with increasing levels of complexity in accordance with the recommendations of the German Society for Ultrasound in Medicine (DEGUM), the European Federation of Societies for ultrasound in Medicine and Biology (EFSUMB) and the World Federation for ultrasound in Medicine and Biology (WFUMB). A longitudinal e-learning system will be implemented in addition to the practical and theoretical teaching units to track and examine the progress of the students.

Conclusion

Early integration of ultrasound training into medical education as part of a structured and standardized broad ultrasound curriculum enables medical students to acquire basic skills and apply them practically. Fundamental scanning skills are acquired by hands-on exercises in small, supervised groups as part of BI-POCUS. BI-POCUS therefore provides an excellent opportunity to improve the clinical skills of future physicians. More research is needed to analyze the learning outcomes for medical students and the improvement of the patient's outcome by establishing such an ultrasound curriculum.

Putting the Cart Before the Horse? Developing a Blended Anatomy Curriculum Supplemented by Cadaveric Anatomy

Cadaveric anatomy is frequently described as the gold standard for anatomy education. Increasingly and especially following the COVID-19 pandemic, there is acceptance that a blended approach for anatomy curriculum delivery is optimal for learners.Setting up a new UK Medical School in 2019 necessitated building a new cadaveric anatomy facility. To enable anatomy curriculum delivery during the construction period (2019-2021), a technology-enhanced learning (TEL) anatomy curriculum was developed, as well as an anatomy laboratory suitable for TEL. Development of a TEL anatomy curriculum with the later inclusion of cadaveric anatomy is unusual since the typical model is to supplement cadaveric anatomy with TEL approaches.TEL solutions that provide digital visualisation of anatomy may support learners by reducing cognitive load. Examples include using colour and/or translucency features to highlight and signpost pertinent anatomy and constructing virtual anatomical models in real time, rather than dissection. Radiology and portable ultrasound provide clinically contextualised visualisations of anatomy; the latter offers a haptic learning experience too. A TEL anatomy laboratory can provide interactive learning experiences for engagement and outreach activities for young school children, where cadaveric anatomy is not suitable.

The effect of short-course point-of-care echocardiography training on the performance of medical interns in children

BACKGROUND

Point-of-care ultrasound (POCUS) can add complementary information to physical examination. Despite its development in several medical specialties, there is a lack of similar studies on children by medical interns and cardiologists. Therefore, investigators aimed to assess the effect of short-course training on the performance of medical interns in point-of-care echocardiography in children.

METHODS

This analytic cross-sectional study was conducted on 161 hospitalized children in 17 Shahrivar children's hospital, Iran, from January 2021 to May 2021. Seven interns (trainees) participated in a short course of point-of-care echocardiography to assess left ventricular ejection fraction (LVEF), inferior vena cava collapsibility index (IVCCI), and the presence of pericardial effusion (PEff). Each patient underwent point-of-care echocardiography by one of the trainees. Then, in less than one hour, the echocardiography was performed by a single cardiologist. Agreement between the cardiologist and trainees was examined using Cohen's kappa coefficient and Prevalence-Adjusted Bias-Adjusted Kappa (PABAK). For numerical variables, the agreement was examined using the concordance correlation coefficient (CCC) and intraclass correlation coefficient (ICC).

RESULTS

Results showed that the cardiologist and trainees detected LVEF >50, IVCCI >50%, and the absence of PEff in most of the participants. A good agreement in terms of ICC and CCC for LVEF (0.832 and 0.831, respectively) and a good agreement in terms of ICC and CCC for IVCCI (0.878 and 0.877, respectively) were noted. Using categorical scoring of LVEF and IVCCI showed 94.4% and 87.6% complete agreement, respectively. Furthermore, using categorical scoring of LVEF and IVCCI, Cohen's kappa coefficient was 0.542 (moderate) and 0.619 (substantial), respectively. The PABAK for LVEF and IVCCI were 0.886 (almost perfect) and 0.752 (substantial), respectively. For PEff, Cohen's kappa and PABAK were 0.797 (moderate) and 0.988 (almost perfect), respectively, and the complete agreement was noted in 160 patients (99.4%).

CONCLUSIONS

This study showed that a short teaching course could help medical interns to assess LVEF, IVCCI, and PEff in children. Therefore, it seems that adding this course to medical interns' curricula can be promising.

Evaluation of antenatal Point-of-Care Ultrasound (PoCUS) training: a systematic review

INTRODUCTION

There is limited access to life-saving antenatal ultrasound in rural and low-resource settings largely due to shortages in skilled staff. Studies have shown healthcare practitioners can be upskilled in PoCUS through focused training, offering a viable solution to this deficit. However, standards for training and competency assessment are unclear and regulation surrounding practice is lacking. We aimed to review published literature examining antenatal PoCUS training programs, comparing teaching approaches and study methodologies.

METHODS

A search of electronic databases EMBASE, MEDLINE and Google Scholar was conducted. Original research articles evaluating antenatal PoCUS training of healthcare professionals worldwide were identified for analysis. Articles with limited detail on the PoCUS training intervention and those describing comprehensive diagnostic training programs were excluded. Evaluations were compared against the Kirkpatrick Evaluation Framework (KEF).

RESULTS

Twenty-seven studies were included from an initial search result of 484 articles. There was considerable heterogeneity between the PoCUS training programs described. Course duration ranged from 3 hours to 2 years, with 11 of the 27 studies delivering obstetric-exclusive content. 44% trained multidisciplinary groups of health professionals. Long-term follow-up training and skills assessments were lacking in over half of the reviewed studies. Study quality and reporting detail varied, but overall beneficial outcomes were reported with 3/4s of the studies reaching upper KEF levels 3 and 4.

CONCLUSION

PoCUS performed by upskilled healthcare professionals offers an attractive solution to the problem of inequitable access to antenatal ultrasound. A review of available literature highlighted a paucity of comparable high-quality studies needed to establish a stronger evidence base for antenatal PoCUS, and a need to standardise training and competency assessment. This review may inform educators, researchers and policy-makers on existing training formats and methodologies to assist in establishing best practice antenatal PoCUS training methods for safe service delivery by remote healthcare professionals.

The Use of Ultrasound in Undergraduate Medical Anatomy Education: a Systematic Review with Narrative Synthesis

This systematic review aimed to synthesize the literature on how ultrasound is currently used in anatomy education within medical schools. A systematic search of Ovid MEDLINE, Scopus, and Educational Resources Information Centre was conducted. Thirty-four relevant unique articles were included from the 1,272 identified from the databases and analyzed via narrative synthesis. Thematic analysis generated two domain summaries: "Successful Aspects of Ultrasound Teaching" and "Barriers to Implementation," each with additional subthemes, aimed to help educators inform best teaching practices from the current evidence base in this field.

International consensus conference recommendations on ultrasound education for undergraduate medical students

OBJECTIVES

The purpose of this study is to provide expert consensus recommendations to establish a global ultrasound curriculum for undergraduate medical students.

METHODS

64 multi-disciplinary ultrasound experts from 16 countries, 50 multi-disciplinary ultrasound consultants, and 21 medical students and residents contributed to these recommendations. A modified Delphi consensus method was used that included a systematic literature search, evaluation of the quality of literature by the GRADE system, and the RAND appropriateness method for panel judgment and consensus decisions. The process included four in-person international discussion sessions and two rounds of online voting.

RESULTS

A total of 332 consensus conference statements in four curricular domains were considered: (1) curricular scope (4 statements), (2) curricular rationale (10 statements), (3) curricular characteristics (14 statements), and (4) curricular content (304 statements). Of these 332 statements, 145 were recommended, 126 were strongly recommended, and 61 were not recommended. Important aspects of an undergraduate ultrasound curriculum identified include curricular integration across the basic and clinical sciences and a competency and entrustable professional activity-based model. The curriculum should form the foundation of a life-long continuum of ultrasound education that prepares students for advanced training and patient care. In addition, the curriculum should complement and support the medical school curriculum as a whole with enhanced understanding of anatomy, physiology, pathophysiological processes and clinical practice without displacing other important undergraduate learning. The content of the curriculum should be appropriate for the medical student level of training, evidence and expert opinion based, and include ongoing collaborative research and development to ensure optimum educational value and patient care.

CONCLUSIONS

The international consensus conference has provided the first comprehensive document of recommendations for a basic ultrasound curriculum. The document reflects the opinion of a diverse and representative group of international expert ultrasound practitioners, educators, and learners. These recommendations can standardize undergraduate medical student ultrasound education while serving as a basis for additional research in medical education and the application of ultrasound in clinical practice.

Implementation of Objective Structured Clinical Examination on Diagnostic Musculoskeletal Ultrasonography Training in Undergraduate Traditional Korean Medicine Education: An Action Research

This study aimed to report the specific methods and investigate the educational effects of diagnostic musculoskeletal ultrasound training and the Objective Structured Clinical Examination (OSCE) for traditional medicine students. Scanning volar wrist and diagnosing carpal tunnel syndrome were selected for musculoskeletal ultrasound to train students to use the basic functions of the ultrasound device and scan various structures including tendons, nerves, and arteries. The students were divided into two groups: one group had 8 weeks of training with mock OSCE experience and received feedback about their scan images, and the other group had 3 weeks of training with flipped learning. The OSCE was implemented on the last day of the training. The subjective learning outcomes were analyzed as students’ evaluation with a 5-point scale, and the objective learning outcomes were analyzed using OSCE scores evaluated with a pre-validated checklist. Of the 111 students, 60 (54.1%) responded to the questionnaire. Overall satisfaction with this ultrasound training was high (4.5 ± 0.60). The average OSCE score in the 8-week group was significantly higher than that in the 3-week group. The students’ self-assessment showed no significant differences between the two groups. Proficiency in using ultrasound is affected by the practice time and feedback. Ultrasound training should be further expanded as a required curriculum to meet students’ needs and achieve learning objectives in the clinical skills education of Korean medicine colleges. Further studies are needed on ultrasound education, especially guided interventions for traditional medicine students.

Implementation of a novel digital ultrasound education tool into an emergency medicine rotation: UltrasoundBox

Objective

We investigated the educational value of implementing a web-based e-learning program into a medical student emergency medicine rotation. We created "UltrasoundBox," a browser-based application where students interpret ultrasound (US) images. Our goal was to assess how this form of e-learning performs when compared to more passive, lecture-based online US education. We also assessed the how the students interpreted the addition this learning modality to the rotation.

Methods

This is a randomized, controlled study to assess the educational outcomes of implementing UltrasoundBox compared to lecture-based US education. Fourth-year medical students on their emergency medicine rotation were enrolled in the study. Students randomized to the control arm were instructed to watch widely available educational lecture videos. Students randomized to the intervention arm received access to UltrasoundBox and were instructed to complete the clinical modules. Both groups completed the same standardized US examination before and after the trial. All the trial participants were given a survey to complete after the trial.

Results

We enrolled 42 students, with 23 in the control group and 19 in the intervention group. On the post-intervention examination, the control and intervention groups were found to have mean examination scores of 61.6% and 73.6% respectively, with a statistically significant difference of 12% (95% confidence interval 1.611 to 5.56; p < 0.0005). A total of 92% of survey respondents in the intervention group indicated that UltrasoundBox was an effective tool in meeting the intended learning objectives, while only 36.8% of the control group indicated this for the online lectures (p < 0.005).

Conclusions

We found that medical students using the web-based e-learning platform UltrasoundBox achieved better scores on the examination when compared to the medical students using existing online lecture-based US educational resources. The students reported that the addition of UltrasoundBox added educational value to the rotation.

Point-of-Care Ultrasound Education During a Pandemic: From Webinar to Progressive Dinner-Style Bedside Learning

Objective: Point-of-care ultrasound (POCUS), traditionally, requires the proximity of learners and educators, making POCUS education challenging during the COVID-19 pandemic. We set out to evaluate three alternate approaches to teaching POCUS in UME. Sessions progressed from an online seminar to a remote, interactive simulation to a “progressive dinner” style session, as precautions evolved throughout the pandemic.

Methods: This prospective study details a series of three POCUS workshops that were designed to align with prevailing social distancing precautions during the COVID-19 pandemic. Overall, 656 medical students were included. The first and second workshops used web-based conferencing technology with real-time ultrasound imaging, with the second workshop focusing on clinical integration through simulation. As distancing precautions were updated, a novel “progressive dinner” technique was used for the third workshop. Surveys were conducted after each session to obtain feedback on students’ attitudes toward alternative teaching techniques and quantitative and qualitative analyses were used.

Results: The initial, remote POCUS workshop was performed for 180 medical students. Ninety-nine (177) percent of students felt the session was “intellectually challenging” and “stimulating.” Ninety-nine percent of students (340/344), after the second workshop, indicated the session was intellectually challenging, stimulating, and a positive learning experience. Students' ability to correctly identify pathologic images increased post-session evaluation from in-session polling. For workshop three, 99% (107/108) of students indicated that the session was “informative.” There was a significant improvement in pre- to post-workshop knowledge regarding image acquisition, interpretation, and clinical integration.

Conclusion: While image acquisition skills are best conveyed at the bedside, these modified POCUS teaching techniques developed and delivered in alignment with COVID-19 pandemic restrictions during a series of three workshops were shown to be effective surrogates for traditional teaching approaches when social distancing requirements, a large learner pool, or lack of local expertise exist.

Adaptation of an anatomy graduate course in ultrasound imaging from in-person to live, remote instruction during the Covid-19 pandemic

Health concerns during the Covid-19 pandemic required the adaptation of a lecture-laboratory course in ultrasound imaging for graduate students from an in-person to a live, remote learning format. The adaptation of in-person lectures to live, remote delivery was achieved by using videoconferencing. The adaptation of in-person laboratory sessions to live, remote instruction was achieved in the first half of the course by providing a hand-held ultrasound instrument to each student who performed self-scanning at their remote locations, while the instructor provided live instruction using videoconferencing. In the second half of the course, the students transitioned to using cart-based, hospital-type instruments and self-scanning in the ultrasound laboratory on campus. The aim of this study was to measure the success of this adaptation to the course by comparing assessment scores of students in the live, remote course with assessment scores of students in the in-person course offered in the previous year. There were no statistically significant differences in the assessment scores of students in the two courses. The adaptation of a course in ultrasound imaging from an in-person to a live, remote learning format during the Covid-19 pandemic described here suggests that contrary to the prevailing view, ultrasound imaging can be taught to students without in-person instruction. The adapted course can serve as a model for teaching ultrasound where instructors and learners are physically separated by constraints other than health concerns during a pandemic.

Musculoskeletal ultrasound training encourages self-directed learning and increases confidence for clinical and anatomical appreciation of first-year medical students

Best-practice guidelines have incorporated ultrasound in diagnostic and procedural medicine. Due to this demand, the Arizona College of Osteopathic Medicine initiated a comprehensive integration of ultrasound into its first-year anatomy course attended by more than 280 students. Ultrasound workshops were developed to enhance student conceptualization of musculoskeletal (MSK) anatomy through visualizing clinically important anatomical relationships, a simulated lumbar puncture during the back unit, carpal tunnel and shoulder evaluations during the upper limb unit, and plantar fascia, calcaneal tendon, and tarsal tunnel evaluations during the lower limb unit. A 5-point Likert scale survey evaluated if ultrasound improved students' self-perceived anatomical and clinical comprehension of relevant anatomy, improved students' ability to orient to ultrasound imagery, and prompted further independent investigation of the anatomical area. Ultrasound examination questions were added to the anatomy examinations. Two-tailed one-sample t-tests for the back, upper limb, and lower limb units were found to be significant across all Likert survey categories (P < 0.001). Positive student responses to the Likert survey in conjunction with examination question average of 84.3% (±10.3) demonstrated that the ultrasound workshops are beneficial to student education. Ultrasound enhances medical students' clinical and anatomical comprehension and ability to orient to ultrasound imagery for MSK anatomy. This study supports early ultrasound education as a mechanism to encourage students' independent learning as evidenced by many undertaking voluntary investigation of clinical concerns associated with MSK anatomy. This study establishes the successful integration of MSK ultrasound into a large medical school program and its benefit to student clinical education.

The State of Point-of-Care Ultrasound Training in Undergraduate Medical Education: Findings From a National Survey

PURPOSE

The primary aim of this study was to evaluate the current state of point-of-care ultrasound (POCUS) integration in undergraduate medical education (UME) at MD-granting medical schools in the United States.

METHOD

In 2020, 154 clinical ultrasound directors and curricular deans at MD-granting medical schools were surveyed. The 25-question survey collected data about school characteristics, barriers to POCUS training implementation, and POCUS curriculum details. Descriptive analysis was conducted using frequency and percentage distributions.

RESULTS

One hundred twenty-two (79%) of 154 schools responded to the survey, of which 36 were multicampus. Sixty-nine (57%) schools had an approved POCUS curriculum, with 10 (8%) offering a longitudinal 4-year curriculum. For a majority of schools, POCUS instruction was required during the first year (86%) and second year (68%). Forty-two (61%) schools were teaching fundamentals, diagnostic, and procedural ultrasound. One hundred fifteen (94%) schools identified barriers to implementing POCUS training in UME, which included lack of trained faculty (63%), lack of time in current curricula (54%), and lack of equipment (44%). Seven (6%) schools identified no barriers.

CONCLUSIONS

Over half of the responding medical schools in the United States had integrated POCUS instruction into their UME curricula. Despite this, a very small portion had a longitudinal curriculum and multiple barriers existed for implementation, with the most common being lack of trained faculty. The data from this study can be used by schools planning to add or expand POCUS instruction within their current curricula.

Ultrasonography in undergraduate medical education: a comprehensive review and the education program implemented at Jichi Medical University

The concept of point-of-care ultrasound has been widely accepted owing to the development of portable ultrasound systems and growing body of evidence concerning its extensive utility. Thus, it is reasonable to suggest that training to use this modality be included in undergraduate medical education. Training in ultrasonography helps medical students learn basic subjects such as anatomy and physiology, improve their physical examination skills, and acquire diagnostic and procedural skills. Technological advances such as simulators, affordable handheld devices, and tele-ultrasound systems can facilitate undergraduate ultrasound education. Several reports have indicated that some medical schools have integrated ultrasound training into their undergraduate medical curricula. Jichi Medical University in Japan has been providing medical students with ultrasound education to fulfill part of its mission to provide medical care to rural areas. Vertical integration of ultrasound education into a curriculum seems reasonable to ensure skill retention and improvement. However, several issues have hampered the integration of ultrasound into medical education, including a lack of trained faculty, the need to recruit human models, requisition of ultrasound machines for training, and limited curricular space; proposed solutions include peer teaching, students as trained simulated patients, the development of more affordable handheld devices, and a flipped classroom approach with access to an e-learning platform, respectively. A curriculum should be developed through multidisciplinary and bottom-up student-initiated approaches. Formulating national and international consensuses concerning the milestones and curricula can promote the incorporation of ultrasound training into undergraduate medical education at the national level.

Students Teaching Students: Student-Led Ultrasound Curriculum in Medical School Education

Introduction

With the expanding use of point-of-care ultrasound throughout medical specialties for the rapid bedside assessment integral to patient care, medical schools have sought to incorporate ultrasound education into their curriculum. Second-year medical students (MS2s) at our institution met this demand by forming the Ultrasound Student Instructor Cadre (USSIC), a longitudinal ultrasound curriculum where MS2s teach first-year medical students (MS1s). The objectives of this study were to assess the ultrasound knowledge of medical students and their perceptions of ultrasound incorporation into their medical education.

Methods

Our flipped classroom curriculum consisted of four lessons (cardiopulmonary, gastrointestinal, genitourinary, and musculoskeletal) composed of videos, didactic lessons, and hands-on probe-time, with 15-minute pre- and post-assessments. Paired Wilcoxon signed-rank tests were performed to evaluate the differences in the pre- and post-assessment scores for each teaching session. Additionally, an end-of-the-year survey assessed the perceived preparedness and overall satisfaction of the MS1s with the course.

Results

The differences between the pre- and post-assessments for each teaching session were statistically significant: cardiopulmonary (45.6 ± 16.9% vs. 82.9 ± 9.4%, p < 0.0001, n = 55), gastrointestinal (53.9 ± 18.0% vs. 84.1 ± 13.5%, p < 0.0001, n = 54), genitourinary (68.9 ± 19.1% vs. 91.4 ± 14.4%, p < 0.0001, n = 64), and musculoskeletal (33.6 ± 14.7% vs. 78.2 ± 18.2%, p < 0.0001, n = 55).

Conclusion

Our study suggests that MS1s met the learning objective for each teaching session. Furthermore, MS1s who became USSIC instructors as MS2s felt more prepared and were more satisfied with the course. This study demonstrates the efficacy of student-led instruction in ultrasound, and we offer our model for adoption into other medical schools.

The Current Status of Ultrasound Education in United States Medical Schools

OBJECTIVES

Ultrasound is used by nearly every medical specialty. Medical schools are integrating ultrasound education into their curriculum but studies show this to be inconsistent. The purpose of this study was to provide an updated description of ultrasound in the curricula of United States Accredited Medical Schools (USAMS).

METHODS

In 2019, USAMS curricular offices were contacted. Institutions were asked about the presence of ultrasound curriculum and for contact information for faculty involved with education. Schools reporting ultrasound curriculum were surveyed regarding details of their curriculum.

RESULTS

Two hundred USAMS were contacted with a response rate of 84%. Of 168 schools, 72.6% indicated they have an ultrasound curriculum. For schools with a curriculum, 79 (64.8%) completed our survey. The majority of survey respondents, 66 (83.5%), indicated having mandatory ultrasound. Ultrasound is primarily integrated into courses (73.8% in basic science courses, 66.2% in clinical skills courses, and 35.4% in clinical rotations). Emergency medicine physicians accounted for 54.7% of course directors. Ten or fewer faculty participate in education in 68.4% of schools and mostly as volunteers. Dedicated machines for education were reported by 78.5% of schools.

CONCLUSIONS

Compared to prior studies, this study had a higher response rate at 84%, and more schools reported ultrasound in their curricula. Emergency medicine represents the majority of leadership in ultrasound education. Despite increased integration of ultrasound into American medical school curricula, its instruction is still inconsistent.

Ultrasound in Medical Education: Can Students Teach Themselves?

INTRODUCTION

A new technology in medical education is ultrasound simulation, which has been shown to help students learn while reducing load on clinical instructors. The goal of this study is to compare the efficacy of teaching using ultrasound simulators versus more traditional instructor-led sessions with ultrasound machines.

METHODS

Ultrasound was used to teach cardiac anatomy and physiology to medical students. Volunteers in one group were instructed using an ultrasound simulator (SonoSim) with built-in lessons; the other group received a traditional instructor-led session with an ultrasound machine. Efficacy of each type of teaching was assessed by measuring improvement from a pre-session test to a post-session test, using a one-sample paired t-test to compare averages between groups. Participants were given a survey to solicit opinions of the lessons.

RESULTS

Twenty-one medical students participated, with 12 in the instructor-led group and 9 in the simulator group. Both groups increased their test scores from pre-session to post-session; the average increase was 5% in the instructor-led and 10% in the simulator group (p = 0.437). There was no statistically significant difference between groups in how effective or enjoyable the lesson felt. Participants from either group who tried both methods were likely to prefer the traditional ultrasound teaching.

CONCLUSION

Self-guided learning with simulators and traditional instructor-led lectures are both effective for teaching basic cardiac anatomy and physiology via ultrasound. However, most students prefer learning with instructors if given the opportunity. Self-guided ultrasound simulators may serve as an effective standalone learning method or an adjunct to instructor-led sessions.

Twelve tips for integrating ultrasound guided peripheral intravenous access clinical skills teaching into undergraduate medical education

Peripheral Intravenous access (PIV) is a procedure undertaken by Medical Practitioners and Non-Medical Practitioners. Traditional PIV uses a visual and tactile technique to locate blood vessels close to the surface of the skin. Chronic medical conditions, dehydration, obesity and recurrent intravenous access can make PIV challenging. Ultrasound (US) guided PIV is recommended to aid the identification of the arm arteries and veins and improve the success rate of needle placement in difficult cases. Medical and non-medical schools, and hospital organisations, are recognising the importance of US guided PIV education for undergraduate and postgraduate Medical and Non-Medical Practitioners. This to promote independence, efficiency and to improve patient safety. The aim of this 12 tips article is to highlight the considerations and practicalities of integrating and delivering, a practical based skills (PBS) session, on the use of US guided practice as an adjunct in difficult PIV, into the undergraduate medical education curricula.

Virtual multispecialty point-of-care ultrasound rotation for fourth-year medical students during COVID-19: Innovative teaching techniques improve ultrasound knowledge and image interpretation

OBJECTIVES

Point-of-care ultrasound (PoCUS) has been integrated into undergraduate medical education. The COVID-19 pandemic forced medical schools to evolve clinical rotations to minimize interruption through implementation of novel remote learning courses. To address the students' need for remote clinical education, we created a virtual PoCUS course for our fourth-year class. We present details of the course's development, implementation, quality improvement processes, achievements, and limitations.

METHODS

A virtual PoCUS course was created for 141 fourth-year medical students. The learning objectives included ultrasound physics, performing and interpreting ultrasound applications, and incorporating PoCUS into clinical decisions and procedural guidance. Students completed a 30-question pre- and posttest focused on ultrasound and knowledge of clinical concepts. PoCUS educators from 10 different specialties delivered the course over 10 days using video-conferencing software. Students watched live scanning demonstrations and practiced ultrasound probe maneuvers using a cellular telephone to simulate ultrasound probe. Students completed daily course evaluations that were used as a continuous needs assessment to make improvements.

RESULTS

A total of 141 students participated in the course; all received a passing grade. The mean pre- and posttest scores improved from 58% to 88% (p < 0.001) through the course duration. Daily evaluations revealed the percentage of students who rated the course's live scanning sessions and didactic components as "very well" increased from 32.7% on day 1 to 69.7% on day 10. The end-of-course evaluation revealed that 91% of students agreed they received effective teaching.

CONCLUSIONS

In response to the COVID-19 pandemic, our multispecialty faculty expeditiously developed a virtual PoCUS curriculum for the entire fourth-year class. This innovative course improved students' ultrasound knowledge, image interpretation, and clinical application while utilizing novel techniques to teach a hands-on skill virtually. As the demand for PoCUS instruction continues to increase, the accessibility of virtual training and blended learning will be beneficial.

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.

Conventional physical examination extended by bedside ultrasound: a new paradigm in nephrological practice

Point-of-Care Ultrasound (POCUS) has been gaining momentum as an extension to physical examination in several specialties. In nephrology, POCUS has generally been used in a restricted way in urinary tract evaluation. We report the case of a patient with nephrotic syndrome secondary to amyloidosis, previously diagnosed by renal biopsy, who was oligosymptomatic when seen the an outpatient clinic, where the POCUS, focused on the heart, lung and abdomen, revealed anasarca, pulmonary congestion and cardiac changes suggestive of cardiac amyloidosis. After evaluation by the cardiology and hematology services, the diagnosis of AL amyloidosis with cardiac involvement was confirmed. This case emphasizes the importance of extending the physical examination using POCUS, which, ideally, should not be restricted to the urinary tract.

Impact of simulator-based training on acquisition of transthoracic echocardiography skills in medical students

Introduction:

Due to the expanding role of ultrasound as a diagnostic tool in modern medicine, medical schools rapidly include ultrasound training in their curriculum. The objective of this study was to compare simulator-based training along with classical teaching, using human models, to impart focused transthoracic echocardiography examination.

Subject and Methods:

A total of 22 medical students, with no former transthoracic echocardiography training, undertook a 90-min e-learning module, dealing with focused echocardiography and important echocardiographic pathologies. Subsequently, they had to complete a multiple-choice-questioner, followed by a 120-min practical training session either on the Heartworks™, (Cardiff, UK) and the CAE Vimedix^®, (Québec, Canada) simulator (n = 10) or on a live human model (n = 12). Finally, both groups had to complete a post-test consisting of ten video-based multiple-choice-questions and a time-based, focused echocardiography examination on another human model. Two blinded expert observers scored each acquired loop which recorded 2 s of each standard view. Statistical analysis was performed with SPPS 24 (SPSS™ 24, IBM, USA) using the Mann-Whitney-Test to compare both groups.

Results:

Analysis of measurable outcome skills showed no significant difference between transthoracic echocardiography training on human models and high-fidelity simulators for undergraduate medical students.

Conclusions:

Both teaching methods are effective and lead to the intended level of knowledge and skills.

Current Use, Perceived Barriers, and Learning Preference of Point of Care Ultrasound (POCUS) in the Emergency Medicine in Qatar - A Mixed Design

Introduction

Point of care ultrasound (POCUS) has been a part of emergency medicine (EM) training for almost two decades. EM training program has a very broad and rigorous POCUS curricula which, in several cases, does not translate to routine application in clinical settings. This study therefore sought to compare the indications, utilization, barriers, and preferred POCUS educational method in a large Middle Eastern academic EM.

Methodology

A validated questionnaire was emailed to 50 EM faculties between April and May 2019. Volunteer faculty members partook in a semi-structured interview to better understand the indications, current use, barriers, and preferred learning method. Responses were anonymous, and data were analyzed with descriptive statistics.

Results

This was a mixed design study. 30/50 (60%) of faculty responded to the survey, with a mean age of 39.2 years and a mean number of years in practice, 13.1. 55% (n=28) completed POCUS training in less than five years, while 45% completed more than five years ago and 5% never completed it. Forty percent of EM physicians were trained in Africa, while 55% were qualified in Asia and 5% completed their training in Europe. The indications and frequently performed procedures were consistent with the previous research. The common barrier reported was lack of time, lack of credentialing, lack of quality assurance, and national guidelines. The majority of the faculty preferred a blended learning approach for POCUS.

Conclusion

POCUS perceived barriers to its full use include time constraints, lack of national guidelines, and credentialing (awarding POCUS qualifications) of the faculty. Blended learning appears to be the preferred approach towards acquiring the knowledge and skills of POCUS.

Team-Based Ultrasound Objective Structured Practice Examination (OSPE) in the Anatomy Course

The clinical use of ultrasound has dramatically increased, necessitating early ultrasound education and the development of new tools in ultrasound training and assessment. The goal of this study was to devise a novel low-resource examination that tested the anatomical knowledge and technical skill of early undergraduate medical students in a gross anatomy course. The team-based ultrasound objective structured practice examination (OSPE) was created as a method for assessing practical ultrasound competencies, anatomical knowledge, and non-technical skills such as teamwork and professionalism. The examination utilized a rotation of students through four team roles as they scanned different areas of the body. This station-based examination required four models and four instructors, and tested ultrasound skills in the heart, abdominal vessels, abdominal organs, and neck regions. A Likert scale survey assessed student attitudes toward the examination. Survey data from participants (n = 46) were examined along with OSPE examination grades (n = 52). Mean and standard deviations were calculated for examination items and survey responses. Student grades were high in both technical (96.5%). and professional (96.5%) competencies with structure identification scoring the lowest (93.8%). There were no statistical differences between performances in each of the body regions being scanned. The survey showed that students deemed the examination to be fair and effective. In addition, students agreed that the examination motivated them to practice ultrasound. The team-based OSPE was found to be an efficient and student-favored method for evaluating integrated ultrasound competencies, anatomical knowledge, team-work, and professional attributes.

Scoping review of implementing a longitudinal curriculum in undergraduate medical education: The wake forest experience

BACKGROUND

Hands-on ultrasound experience has become a desirable component for undergraduate medical education (UGME) curricula throughout medical schools in the United States (US) to enhance readiness for future training. Ultrasound integration can be a useful assistive educational method in undergraduate medical education to improve anatomy and physiology skills. Relatively few medical schools have integrated ultrasound experiences formally into their 4-year medical school curriculum due to limitations of a resource intensive set up.

METHODS

We undertook a scoping review of published UGME ultrasound curricula integrated into all four years in peer-reviewed as well online literature. In addition, we provide a narrative review of our institutional experience in conceptualization, design and implementation of UGME ultrasound curriculum driven by need to address the fading knowledge in anatomy and physiology concepts beyond pre-clinical years.

RESULTS

Integrated ultrasound curriculum at WFSOM utilizes focused ultrasonography as a teaching aid for students to gain a more thorough understanding of basic and clinical science concepts taught in the medical school curriculum. We found 18 medical schools with ultrasound curricula published in peer-reviewed literature with a total of 33 ultrasound programs discovered by adding Google search and personal communication CONCLUSIONS: The results of the review and our institutional experience can help inform future educators interested in developing similar curricula in their undergraduate programs. Common standards, milestones and standardized competency-based assessments would be helpful in more widespread application of ultrasound in UGME curricula.
