International consensus conference recommendations on ultrasound education for undergraduate medical students

Principles for Developing a Large-Scale Point-of-Care Ultrasound Education Program: Insights from a Tertiary University Medical Center in Israel

Background & Need for Innovation

Point-of-care ultrasound (POCUS) has transformed bedside diagnostics, yet its operator-dependent nature and lack of structured training remain significant barriers. To address these challenges, Ben Gurion University (BGU) developed a longitudinal six-year POCUS curriculum, emphasizing early integration, competency-based training, and scalable educational strategies to enhance medical education and patient care.

Goal of Innovation

To implement a structured and scalable POCUS curriculum that progressively builds technical proficiency, clinical judgment, and diagnostic accuracy, ensuring medical students effectively integrate POCUS into clinical practice.

Steps Taken for Development and Implementation

The curriculum incorporates hands-on training, self-directed learning, a structured spiral approach, and peer-led instruction. Early exposure in physics and anatomy courses establishes a foundation, progressing to bedside applications in clinical years. Advanced technologies, including AI-driven feedback and telemedicine, enhance skill retention and address faculty shortages by providing scalable solutions for ongoing assessment and feedback.

Evaluation of Innovation

Since its implementation in 2014, the program has trained hundreds of students, with longitudinal proficiency data from over 700 students. Internal studies have demonstrated that self-directed learning modules match or exceed in-person instruction for ultrasound skill acquisition, AI-driven feedback enhances image acquisition, and early clinical integration of POCUS positively influences patient care. Preliminary findings suggest that telemedicine-based instructor feedback improves cardiac ultrasound proficiency over time, and AI-assisted probe manipulation and self-learning with ultrasound simulators may further optimize training without requiring in-person instruction.

Critical Reflection

A structured longitudinal approach ensures progressive skill acquisition while addressing faculty shortages and training limitations. Cost-effective strategies, such as peer-led instruction, AI feedback, and telemedicine, support skill development and sustainability. Emphasizing clinical integration ensures students learn to use POCUS as a targeted diagnostic adjunct rather than a broad screening tool, reinforcing its role as an essential skill in modern medical education.

Measurement and Normal Values, Pathologies, Interpretation of findings, and Interventional Ultrasound as part of student ultrasound education

Ultrasound diagnostics is a widely used, radiation-free, cost-effective, and bedside-applicable imaging technique. Given its numerous advantages and broad application, it appears reasonable to integrate practical use and theory into medical education at an early stage. Since the content of student ultrasound courses varies significantly on an international scale, the aim of this paper is to establish foundations for a more standardized approach to student's ultrasound education (SUSE) especially with focus on abdominal ultrasound. This review examines to what extent measurements can be effectively incorporated into student ultrasound training and under which conditions the teaching of pathologies should be included in these courses. Additionally, the handling of false-positive and false-negative findings in student training is discussed. Considering the growing relevance of interventional ultrasound (INVUS), the paper further explores the extent to which interventional procedures should already be taught during SUSE.

How to Design a Point-of-Care Ultrasound Training Course Using Educational Theories

ABSTRACT

Point-of-care ultrasound proficiency requires the integration of spatial anatomic knowledge, technical hands-on image acquisition, and the ability to interpret images and incorporate findings into clinical decision-making. Effectively teaching these skills requires a structured approach. This article presents a comprehensive framework for designing a point-of-care ultrasound course tailored to continuing professional development. We demonstrate how applying the learning theories of cognitivism, behaviorism, and constructivism can facilitate the educational experience. In addition, we offer guidance on maintaining learner engagement, organizing didactic sessions, and delivering standardized feedback.

Ultrasound technology as a tool to teach basic concepts of physiology and anatomy in undergraduate and graduate courses: a systematic review

Many publications describe use of ultrasound imaging in teaching of clinical courses, primarily integrated with clinical applications. More recently there have been increasing numbers of papers describing ultrasound as a tool primarily for teaching basic anatomy and physiology concepts rather than clinical applications. Of these, many have described qualitative analysis with a consensus that its use is viewed very positively by students for aiding learning. Far fewer studies have attempted quantitative analysis to support this belief, and conclusions have been varied. A review of studies was conducted that included those that used ultrasound to teach physiology and anatomy concepts. Studies were excluded if they did not contain quantitative or qualitative assessment of efficacy. Medline and Embase databases were searched (11/16/22) and screened by two independent reviewers. Forty-six studies were included, with data extracted relating to cohort characteristics, ultrasound intervention, quantitative or qualitative assessments, and any barriers to implementation. It was confirmed that both student and teacher opinions are extremely favorable in most cases. Although conclusions from quantitative studies were not as clear, there was evidence that ultrasound is at least as effective as more conventional teaching methods and could have significantly better performances in short-term assessments. However, varied methods of teaching intervention, experimental protocols, and assessment of learning may have contributed to the lack of clarity. Within this context, some of the problems encountered with implementing ultrasound as an educational tool (such as financial and temporal constraints), and in conducting more definitive studies, are discussed.NEW & NOTEWORTHY This first systematic review of ultrasound use as a teaching tool in basic anatomy and physiology confirmed that students and staff believe incorporation is beneficial to learning and is highly popular. Quantitative data are scarcer but show that it is at least as effective as more conventional teaching methods and can enhance short-term recall. Good-quality studies with adequate comparisons and assessment methods are still lacking, so further work in this area is needed.

Development of a Cadaveric Breast Ultrasound Module and Analysis of Its Effectiveness Among Medical Students

Information characterizing a standardized breast ultrasound curriculum in medical education is lacking, and due to the sensitive nature of this imaging, medical schools encounter difficulties in obtaining standardized patients for practicing these skills. Therefore, a supplemental, cadaver-based, point-of-care ultrasound (POCUS) module was created to introduce preclinical medical students to breast anatomy and pathology (IRB #1950978). Participants (n = 104) completed a 16-item, pre-instruction assessment followed by an online breast ultrasound module. After, participants completed a 60-min, in-person training session using donor models to examine (1) normal breast tissue, (2) fluid-filled cysts, (3) benign and malignant solid lesions, and (4) breast implants; a 19-item, post-instruction assessment was completed. Comparison of mean scores from the multiple choice, knowledge-based items in the pre- and post-assessments demonstrated improvement in knowledge gained (pre, 5.08; post, 7.78) (p = 0.001); Cronbach's alpha, pre, 0.199 vs. post, 0.596. Participant perceptions were evaluated using a Likert survey; participants noted strong agreement (77%) or agreement (17%) with the benefit of and strong agreement (32%) or agreement (55%) regarding confidence in performing breast ultrasound (Cronbach's alpha: pre, 0.705; post = 0.755). Analysis of open responses revealed five themes: positive feedback (74.5%), appreciation/thanks (35.3%), emphasis of hands-on learning (21.6%), desire for additional sessions (19.6%), and suggestions for improvement (17.6%). Positive results from the introduction of a cadaver-based breast ultrasound module early in medical students' careers show promise and should be a consideration when discussing its integration into preclinical curriculum.

High-Frequency and Ultra-High-Frequency Ultrasound in Dermatologic Diseases and Aesthetic Medicine

Dermatologic ultrasonography applications are rapidly growing in all skin fields. Thanks to very high spatial resolution, high-frequency and ultra-high-frequency ultrasound can evaluate smaller structures, allowing us to improve diagnosis accuracy and disease activity. Moreover, they can guide treatment, such as drug injection, and assess therapy efficacy and complications. In this narrative review, we evaluated high-frequency ultrasound and ultra-high-frequency ultrasound in infections, inflammatory dermatoses, metabolic and genetic disorders, specific cutaneous structure skin disorders, vascular and external-agent-associated disorders, neoplastic diseases, and aesthetics.

Cardiac Ultrasound Training for Medical Students Utilizing Drawing and Ward-Based Instruction

Introduction

In this report, we present a cardiac ultrasound training module for medical student learners. The module assists medical students in developing foundational skills in image acquisition, identification of normal cardiac ultrasound anatomy, and demonstration of professionalism when performing the associated OSCE exam.

Methods

We delivered the module across a 2-week cardiology rotation. On the first day, participants completed a pretest, a 1-hour introductory tutorial including a drawing exercise, and 1-hour of supervised practice with ward patients. Following supervised practice, participants were provided with an ultrasound machine for self-directed practice over the remainder of the clinical rotation. On the final day, participants completed a posttest and module evaluation. Pre- and posttest OSCE scores were compared to assess participants' cardiac ultrasound skills.

Results

A total of 121 students completed the module, of whom 116 completed the pre- and posttest. Median OSCE scores improved from 6 to 24 out of 39 (p < .001). Before the module, 9% of participants agreed or strongly agreed they were able to identify cardiac anatomy on an ultrasound of the heart, which increased to 98% after the module. Following the module, 92% of participants agreed or strongly agreed that ultrasound training helped with other learning on the cardiology rotation.

Discussion

We demonstrated that a brief training session followed by self-directed ward-based practice improved cardiac ultrasound skills in undergraduate medical students. Participants felt more confident identifying cardiac anatomy, and a large proportion felt the ultrasound training helped with other learning objectives on the cardiology rotation.

Investigating medical students' perceptions of point-of-care ultrasound integration into preclinical education

INTRODUCTION

Recent international consensus statements advocate for the integration of Point-of-Care Ultrasound (PoCUS) into the global undergraduate medical curriculum. Some medical schools outside Saudi Arabia have already incorporated PoCUS into their undergraduate curricula to enhance anatomy, physiology and pathology instruction. However, there are no data on the potential role of PoCUS in the preclinical training of medical students in Saudi Arabia. Given constraints on resources for medical education, a formal needs assessment was conducted to evaluate the potential utility of PoCUS within the basic science curriculum at our institution.

METHODS

All final year medical students at our institution were invited to complete a validated online survey. The questionnaire utilized a 5-point Likert scale to assess student perceptions of the potential for PoCUS to improve their understanding of basic sciences and their desire for its incorporation into the preclinical curriculum.

RESULTS

A total of 229 students participated (response rate 76%; male 134/200; female 95/100). Our survey demonstrated good internal consistency (Cronbach's alpha: learning basic sciences 0.81, need for curriculum integration 0.83). The vast agreed that learning PoCUS would enhance their understanding of anatomy (95%) and pathology (75%). While only 52% agreed that learning PoCUS would improve their understanding of physiology, a substantial majority (80%) agreed that all medical schools should incorporate PoCUS into their undergraduate curricula. Furthermore, 62% agreed that offering PoCUS training would make the medical school more attractive to prospective applicants. No significant differences were observed between the responses of male and female students. The results of a confirmatory factor analysis provide strong support for the hypothesized three-factor model. All factor loadings are significant (P < 0.001), CONCLUSIONS: Medical students in Saudi Arabia perceive that PoCUS would be a valuable tool to learn anatomy and pathology, aligning with the recommendations of the consensus conference on PoCUS integration in undergraduate medical education organized by the World Interactive Network Focused on Critical Ultrasound (WINFOCUS) and the Society of Ultrasound in Medical Education (SUSME). Introducing PoCUS training into preclinical medical curricula may also enhance the attractiveness of medical schools to potential applicants.

Third-year medical students' perceptions of confidence and readiness to perform EFAST after training

BACKGROUND

As Point-of-Care Ultrasound (POCUS) education is increasingly incorporated in undergraduate medical education (UME), evaluation of the effectiveness of various ultrasound-related curricula is a developing field. The Extended Focused Assessment with Sonography (EFAST) is a POCUS exam widely used in emergency medicine. This project examines third-year osteopathic medical (OMS III) students' perceptions of the impact of a focused introduction to EFAST training curriculum on their performance ability and utilization of EFAST during third-year clinical rotations. Furthermore, we assessed student perceptions of barriers to the use of POCUS during third-year clinical rotations.

METHODS

The introduction to EFAST curriculum was developed using competency-based backward design and was delivered in July 2022 to incoming OMS III students. The curriculum involved didactics, hands-on ultrasound practice with standardized patients, and a comprehensive OSCE assessment, where students performed the EFAST exam. In July/August 2023, curriculum participants were anonymously surveyed regarding the effectiveness of the EFAST curriculum and perceived barriers to EFAST and POCUS utilization during their third-year clerkships. Descriptive and thematic analyses were performed on quantitative and qualitative data.

RESULTS

Twenty-one of 69 (30.4%) participants responded to the survey, with 17 (24.6%) participants completing the entire survey. Respondents reported increased knowledge and confidence in performing and interpreting EFAST, with 82.4% indicating increased likelihood of performing EFAST and POCUS in general. 76.4% performed EFAST at least once during third-year clerkships, with 11.8% performing it 15 times or more. Students reported valuing the safe simulated learning environment of the EFAST training, and identified lack of patients with indications for EFAST, time constraints, lack of ultrasound machine availability and clinician comfort level as barriers to EFAST utilization.

CONCLUSIONS

This study presents the implementation of a focused EFAST curriculum developed through competency-based deliberate backward design based on professional guidelines and the anticipated educational needs of our institution and community. Student perceptions provided valuable insight into access and barriers to EFAST and POCUS use in subsequent clinical clerkships, indicating student perception of POCUS curriculum effectiveness may provide insight to continual curriculum improvement.

Perceived discrepancies in neurosonology training and certification across Europe: a RRFS/EAN survey

Introduction

Neurosonology is a vital paraclinical investigation in modern neurology. However, access to education and certification in neurosonology for neurology residents and young specialists in Europe is challenging, and comprehensive data regarding this topic are scarce. Information regarding difficulties in neurosonology training across Europe may help bring this topic under the spotlight and act as a call for the harmonization of curricula across the continent.

Methods

We performed an online survey targeting European neurology residents and young specialists, focusing on neurosonology training and certification. The survey was conducted between May and September 2023 and received responses from 282 participants representing 37 European countries.

Results

There were disparities in neurosonology training during residency, with 6 (16.2%) out of 37 countries reporting a dedicated curriculum. The respondents expressed an overall lack of satisfaction with theoretical knowledge (rating their experience as very poor 28.0%, poor 20.2%, neutral 25.9%, good 19.3%, and very good 6.6%) and practical skills gained during their training (rating their experience as very poor 30.9%, poor 18.9%, neutral 22.6%, good 18.1%, and very good 9.5%). A total of 282 respondents (5.7%), 16 held a national certification in neurosonology, claiming obstacles such as high costs of certification and a limited number of certifying centers.

Discussion

This survey reveals significant variations in neurosonology training across Europe, indicating difficulties in obtaining certification. Despite the increasing importance of neurosonology, many neurologists feel inadequately prepared and lack practical training during residency, emphasizing the need for better and more standardized access.

Conclusion

The survey underscores challenges and disparities in neurosonology training and certification in Europe. Standardization of curricula and increased awareness about available certifications are crucial to address these issues. The interest in European Certification suggests a potential solution for enhancing neurosonology training at the international level.

Undergraduate musculoskeletal ultrasound training based on current national guidelines-a prospective controlled study on transferability

INTRODUCTION

Musculoskeletal ultrasound (MSUS) is integral to routine clinical diagnostics for musculoskeletal and joint disorders. This study aims to establish and validate a sonography course tailored to undergraduate medical students acquiring MSUS-specific skills at a German university.

METHODS

A blended learning training concept, comprising 24 instruction sessions of 45 min each, was designed based on the current national guidelines of the German Society for Ultrasound in Medicine (DEGUM). This program was integrated into the clinical phase of the undergraduate students' medical education. The self-perceived improvement in competency and the effectiveness of the course design were evaluated using a a 7-point Likert scale questionnaire. Objective learning success was evaluated via a written test and a "Direct Observation of Practical Skills" practical exam. Control groups included medical students without MSUS training (control group 1) and doctors who had completed DEGUM-certified basic MSUS courses (control group 2). Both control groups completed the written test, while control group 2 also took the practical final exam. The study involved 146 participants: 56 were allocated to the study group, 44 to control group 1, and 46 to control group 2.

RESULTS

The study group rated their skills significantly higher after the course (p < 0.01). Participants expressed high satisfaction with the course design, the teaching materials, and the teachers. The study group's performance on the final written test was comparable to those of control group 2 (p = 0.06) and significantly superior to control group 1 (p < 0.001). Additionally, the study group's performance on the practical final exam was not significantly different from control group 2 (p = 0.28), with both groups achieving scores exceeding 80%.

CONCLUSION

Both subjective and objective measures of learning suggest that an MSUS course designed for postgraduates can be effectively adapted for undergraduate medical students. Incorporating MSUS training into the clinical curriculum is recommended to enhance future medical professionals' educational experience and practical skills.

Tailoring Ultrasound Training to Clinical Anatomists of Varying Experience Levels

A lack of trained faculty is a frequently reported barrier to integrating ultrasound training into medical education. Clinical anatomy faculty are a promising pool from which to recruit and train new ultrasound educators. To date, there are no studies related to best practices for training anatomists in ultrasound skills and preparing them to teach the next generation of health care providers this crucial clinical skill. This report follows the development of a hands-on ultrasound training course for clinical anatomy educators and lists learner needs aggregated by prior experience level and provides best practices for training these professionals in ultrasound skills.

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.

Student ultrasound education, current view and controversies. Role of Artificial Intelligence, Virtual Reality and telemedicine

The digitization of medicine will play an increasingly significant role in future years. In particular, telemedicine, Virtual Reality (VR) and innovative Artificial Intelligence (AI) systems offer tremendous potential in imaging diagnostics and are expected to shape ultrasound diagnostics and teaching significantly. However, it is crucial to consider the advantages and disadvantages of employing these new technologies and how best to teach and manage their use. This paper provides an overview of telemedicine, VR and AI in student ultrasound education, presenting current perspectives and controversies.

Guidance for performance, utilization, and education of cardiac and lung point-of-care ultrasonography from the Japanese Society of Echocardiography

In recent years, bedside ultrasound examinations have been used in many clinical departments and are called point-of-care ultrasound (POCUS). Regarding POCUS in the cardiac field, a protocol called focus (focused) cardiac ultrasound (FoCUS) has been developed in Europe and the United States, is being used clinically, and an educational syllabus has been created. According to them, FoCUS is defined as a point-of-care cardiac ultrasound examination using standardized limited sections and protocols. FoCUS is primarily intended to be performed by non-cardiologists, and in order to avoid making mistakes in judgment, it is important to be familiar with its limitations and it is necessary to understand pathological conditions that can only be diagnosed using conventional comprehensive echocardiography. The Japanese Society of Echocardiography has edited this clinical guideline because we believe that FoCUS should be used effectively and appropriately in Japan, and that appropriate education is essential to popularize FoCUS in Japan. Furthermore, lung POCUS has recently come into clinical use. Lung POCUS is useful for the diagnosis and follow-up of heart failure when used in conjunction with FoCUS, and is especially useful in primary care where chest X-rays are not available. The working group that created this manual agreed that it is desirable to educate patients about lung POCUS in conjunction with FoCUS, so we decided to include the basic techniques of lung POCUS and how to use them in this manuscript.

First insights of integrating the Bonn Internship Curriculum for Point-of-Care Ultrasound (BI-POCUS): progress and educational aspects

BACKGROUND

Point-of-care ultrasound (POCUS) is rapidly gaining prominence in various clinical settings. As its use becomes more widespread, there is a growing need for comprehensive ultrasound training in medical education to ensure that future healthcare professionals are proficient in this essential diagnostic tool.

OBJECTIVE

This study is the first attempt by the University of Bonn to seamlessly integrate ultrasound courses and the use of ultrasound devices into the regular activities of final year medical students and to evaluate the usage of these devices.

METHODS

A total of forty students in their practical year were provided with a hendheld ultrasound device for a period of four months. During this time, they were invited to take part in eight optional ultrasound courses in which they acquired images and those images were rated using a specially developed rating system. At the end of the tertial, students were able to take part in a voluntary survey on the use of the equipment.

RESULTS

Participation in the optional ultrasound courses was well received, with the Introduction and FAST module drawing the largest number of participants (29). Among the ultrasound images acquired by students, those of the lungs obtaining the highest rating, with 18.82 (SD ± 4.30) points out of 23 points, while the aorta and vena cava images scored lowest, with an average of 16.62 (SD ± 1.55) points. The overall mean score for all images was 17.47 (SD ± 2.74). Only 21 students responded to the survey. Of the participating students, 67% used the device independently four times or fewer during the tertial.

CONCLUSION

The study aimed to enhance the BI-POCUS curriculum by improving students' ultrasound skills during their practical year. However, device usage was lower than expected, with most students using it only once a month or less. This raises concerns about the justification of the effort and resources. Future initiatives will focus on technical improvements, better login data provision, and closer monitoring of usage and progress, emphasizing the need for practical ultrasound training in medical education.

Teledidactic Versus Hands-on Teaching of Abdominal, Thoracic, and Thyroid Ultrasound-The TELUS II Study

BACKGROUND

The worldwide COVID-19 pandemic has initiated a change in medical education and the development of new teaching concepts has become inevitable to maintain adequate training.

OBJECTIVE

This pilot study aims to compare teledidactic teaching with traditional face-to-face teaching for abdominal, thoracic, and thyroid ultrasound.

DESIGN

Concurrently, a teledidactic and a face-to-face ultrasound course were held. The students completed seven 90-min modules using mobile ultrasound probes (Butterfly IQ). Each module consisted of a lecture, a demonstration of probe guidance, and independent training.

PARTICIPANTS

A total of thirty medical students took part in the study and were randomly assigned to a teledidactic and a face-to-face group.

MAIN MEASURES

An objective structured assessment of ultrasound skills (OSAUS) was performed as a pre-test and as the final exam and ultrasound images obtained during the exam were evaluated using the brightness mode quality ultrasound imaging examination (B-QUIET) scale.

KEY RESULTS

No significant difference between the two cohorts on the OSAUS final exam was shown (p > 0.05 in all modules). There was a significant difference in the assessment of the images in the focused assessment with sonography for trauma (FAST) (p 0.015) and aorta (p 0.017) modules. Students in the teledidactic group performed better in both modules, scoring 33.59 (± 2.61) out of 44 in the module FAST (face-to-face group 30.95 (± 1.76)) and aortic images averaged 35.41 (± 2.61) points (face-to-face group 32.35 (± 3.08)).

CONCLUSIONS

A teledidactic course for abdominal and thoracic ultrasound examinations is equally effective to traditional face-to-face teaching in this pilot study. Digital implementation with a portable ultrasound machine could be a great opportunity to promote ultrasound education worldwide and over great distances.

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.

Current perception and barriers to implementing lung ultrasound in Canadian neonatal intensive care units: a national survey

Despite the growing body of literature supporting the use of point-of-care lung ultrasound (POC-LU) in neonates, its adoption in Canadian neonatal intensive care units (NICUs) remains limited. This study aimed to identify healthcare providers' perceptions and barriers to implementing POC-LU in Canadian NICUs. We conducted an electronic survey targeting neonatologists, neonatal fellows, neonatal nurse practitioners, and registered respiratory therapists in 20 Canadian NICUs. The survey comprised a 28-item questionnaire divided into four sections: (1) participants' demographics and availability of POC-LU equipment, (2) experience and interest in POC-LU learning, (3) perception of POC-LU as a diagnostic tool, and (4) barriers to POC-LU implementation in NICUs. A total of 194 participants completed the survey, with neonatologists comprising the majority (45%). Nearly half of the participants (48%) reported prior experience with POC-LU. The most prevalent indications for POC-LU use were diagnosis of pleural effusion (90%), pneumothorax (87%), and respiratory distress syndrome (76%). Participants identified the primary barrier to POC-LU adoption as the lack of trained providers available for both training and clinical integration. Notably, most respondents (87%) expressed keen interest in learning neonatal POC-LU. A subgroup analysis based on the responses collected from NICU-directors of 12 institutions yielded results consistent with those of the overall participant pool.     Conclusion: This survey underscores the perceived importance of POC-LU among NICU healthcare providers. A Canadian consensus is required to facilitate the development of widespread training programs as well as standardized clinical practice guideline for its implementation. What is Known: • In recent years, point-of-care lung ultrasound (POC-LU) has emerged as an important tool in neonatology, revolutionizing the assessment and management of critically ill infants. However, its adoption in Canadian Neonatal Intensive Care Units remains limited. What is New: • Most Canadian healthcare providers showed high level of interest in learning POC-LU techniques. Additionally, POC-LU was perceived as a useful tool for diagnosis and guiding intervention in various neonatal respiratory diseases. Nonetheless, the lack of expertise emerged as the primary barrier to its adoption and practice across different groups of participants regardless of their clinical experience level.

Pediatric ultrasound practice in Italy: an exploratory survey

BACKGROUND

The aim of this exploratory survey is to describe the current state of US (ultrasound) technique across different pediatric settings nationwide.

METHODS

A questionnaire was emailed to all members of the Italian Society of Pediatrics, including pediatric residents. The survey was open from December 2021 to March 2022.

RESULTS

There were 1098 respondents. Seven hundred and seven pediatricians (84.1%) reported any use of US, while 51 (44.3%) residents denied it. The majority of participants (n = 956, 87.1%) reported to have a US machine available within the department, mostly cart-based (n = 516, 66.9%) and provided from 1 to 5 years prior to the survey (n = 330, 42.8%). Lung and neonatal cerebral regions were the most frequently scanned (n = 289, 18.7% and n = 218, 14.1%, respectively). The suspicion of pneumonia or respiratory distress represented the main reasons for performing US in emergency room (n = 390, 78% and n = 330, 66%, respectively). The majority of family pediatricians reported to scan lung and kidney/urinary tract regions (n = 30, 16.9%, and n = 23,12.9%, respectively). Regarding US training, the majority of respondents (n = 358, 34.6%) declared an experience-based education, with a deficient certification enabling the use of US in 71.6% (n = 552) of cases. The most common barriers included the lack of a well-defined training program (n = 627, 57.1%), unavailability of the US machine (n = 196, 17.9%) and legal responsibility concern (n = 175, 15.9%).

CONCLUSIONS

Despite the growing interest on pediatric US nationally, significant barriers still limit widespread adoption. These obstacles may be addressed through the dissemination of a specific US education plan and providing additional resources.

Effects of undergraduate ultrasound education on cross-sectional image understanding and visual-spatial ability - a prospective study

INTRODUCTION/AIM

Radiological imaging is crucial in modern clinical practice and requires thorough and early training. An understanding of cross-sectional imaging is essential for effective interpretation of such imaging. This study examines the extent to which completing an undergraduate ultrasound course has positive effects on the development of visual-spatial ability, knowledge of anatomical spatial relationships, understanding of radiological cross-sectional images, and theoretical ultrasound competencies.

MATERIAL AND METHODS

This prospective observational study was conducted at a medical school with 3rd year medical students as part of a voluntary extracurricular ultrasound course. The participants completed evaluations (7-level Likert response formats and dichotomous questions "yes/no") and theoretical tests at two time points (T1 = pre course; T2 = post course) to measure their subjective and objective cross-sectional imaging skills competencies. A questionnaire on baseline values and previous experience identified potential influencing factors.

RESULTS

A total of 141 participants were included in the study. Most participants had no previous general knowledge of ultrasound diagnostics (83%), had not yet performed a practical ultrasound examination (87%), and had not attended any courses on sonography (95%). Significant subjective and objective improvements in competencies were observed after the course, particularly in the subjective sub-area of "knowledge of anatomical spatial relationships" (p = 0.009). Similarly, participants showed improvements in the objective sub-areas of "theoretical ultrasound competencies" (p < 0.001), "radiological cross-section understanding and knowledge of anatomical spatial relationships in the abdomen" (p < 0.001), "visual-spatial ability in radiological cross-section images" (p < 0.001), and "visual-spatial ability" (p = 0.020).

CONCLUSION

Ultrasound training courses can enhance the development of visual-spatial ability, knowledge of anatomical spatial relationships, radiological cross-sectional image understanding, and theoretical ultrasound competencies. Due to the reciprocal positive effects of the training, students should receive radiology training at an early stage of their studies to benefit as early as possible from the improved skills, particularly in the disciplines of anatomy and radiology.

Utility of focused cardiac ultrasonography training in veterinary students to differentiate stages of subclinical myxomatous mitral valve disease in dogs

BACKGROUND

Differentiation of the subclinical phases of myxomatous mitral valve disease (MMVD) in dogs relies heavily on echocardiography. Focused cardiac ultrasonography (FCU) is a point-of-care technique that can assess heart size.

HYPOTHESIS/OBJECTIVES

Veterinary students trained in FCU can differentiate dogs with subclinical MMVD based on left ventricular (LV) and left atrial (LA) dimensions.

ANIMALS

Forty-eight dogs with subclinical MMVD.

METHODS

Veterinary students were trained to measure LV dimension and LA-to-aortic root dimension ratio (LA : Ao) using FCU. Dogs were categorized into 2 cohorts based on whether or not the LV normalized internal diastolic dimension was ≥1.7 and LA : Ao was ≥1.6. Agreement between FCU and echocardiographic studies performed by cardiologists was evaluated.

RESULTS

One-hundred and forty-six FCU examinations were performed by 58 veterinary students on 48 dogs. Overall agreement between students and cardiologists was moderate (Fleiss' kappa, 0.54; 95% confidence interval [CI], 0.39-0.69; P < .001). Percentage accuracy in observations with heart dimensions less than the cutoffs (86/89, 97%) was significantly higher than in observations in with larger hearts (31/57, 54%; P < .001). Agreement increased from moderate to good as heart sizes became more extreme. Degree of confidence by students in performing FCU was significantly higher at the end vs start of the study.

CONCLUSIONS AND CLINICAL IMPORTANCE

Categorization of dogs with subclinical MMVD by veterinary students using FCU was associated with moderate to good agreement with echocardiography. Focused cardiac ultrasonography is a point-of-care method that can help assess clinical stage in dogs with subclinical MMVD.

Trends in Point of Care Ultrasound Familiarity Among Undergraduate Medical Clerkship Educators

OBJECTIVES

Despite growing use of point of care ultrasound (POCUS), there remains a paucity of data about familiarity with POCUS among educators who dictate curricular content in undergraduate medical education. This paper aims to longitudinally characterize the level of comfort and frequency of POCUS use among faculty involved in undergraduate clerkship education.

METHODS

A web-based cross-sectional survey assessing comfort, frequency of use, and awareness of indications for POCUS among faculty involved in Internal Medicine, Family Medicine, and Surgery undergraduate clerkship education in a single urban academic medical center in 2016 and again in 2022.

RESULTS

A total of 45 responses from 2016 and 30 responses from 2022 are included. The percentage of faculty "not comfortable" with performing POCUS decreased from 78% to 46%, although the overall change in comfort was not statistically significant. Comfort interpreting POCUS images, frequency of POCUS use, and familiarity with the clinical applications of POCUS all improved. Faculty identified multiple barriers to more frequent POCUS use.

CONCLUSIONS

Over a six-year period at one urban, academic medical center, comfort with POCUS and frequency of use have increased slightly but remain low among core faculty responsible for clerkship education. There are still large gaps in knowledge and very few faculty regularly use POCUS, which can be attributed to multiple different barriers.

Consensus-based ethical best practices for performing educational point-of-care ultrasonography in the emergency department

Objectives

There is no standardized protocol for performing educational point-of-care ultrasonography (POCUS) that addresses patient-centered ethical issues such as obtaining informed consent. This study sought to define principles for ethical application of educational POCUS and develop consensus-based best practice guidance.

Methods

A questionnaire was developed by a trained ethicist after literature review with the help of a medical librarian. A diverse panel including experts in medical education, law, and bioethics; medical trainees; and individuals with no medical background was convened. The panel voted on their level of agreement with ethical principles and degree of appropriateness of behaviors in three rounds of a modified Delphi process. A high level of agreement was defined as 80% or greater consensus.

Results

Panelists voted on 38 total items: 15 related to the patient consent and selection process, eight related to practices while performing educational POCUS, and 15 scenarios involving POCUS application. A high level of agreement was achieved for 13 items related to patient consent and selection, eight items related to performance practices, and 10 scenarios of POCUS application.

Conclusions

Based on expert consensus, ethical best practices include obtaining informed consent before performing educational POCUS, allowing patients to decline educational POCUS, informing patients the examination is not intended to be a part of their medical evaluation and is not billed, using appropriate draping techniques, maintaining a professional environment, and disclosing incidental findings in coordination with the primary team caring for the patient. These practices could be implemented at institutions to encourage ethical use of educational POCUS when training physicians, fellows, residents, and medical students.

Teaching ultrasound in osteopathic medical schools

CONTEXT

An important diagnostic tool, ultrasound (US) has been incorporated into the curriculum of medical schools for more than 20 years. In the last decade, the interest in US educational research has experienced exponential growth but mostly from Medical Doctor (MD)-granted schools. The extent to which US is embedded in the curricula of the colleges of osteopathic medicine (COM) still requires a comprehensive evaluation.

OBJECTIVES

This survey is designed to evaluate the current status of US teaching in COMs with an emphasis on the inclusion of the US in osteopathic manipulative medicine (OMM) training.

METHODS

An anonymous, voluntary, 22-question online survey was created and administered to all COMs to collect data about the current state of US teaching. A descriptive analysis was performed to describe and summarize the final data. Fisher's exact test was utilized for the comparison of study variables.

RESULTS

We received responses from 36 of the 43 (83.7 %) COMs invited to participate in the survey, all of which had US training within their curriculum, most commonly integrated into the year 1 curriculum (86.1 %). Focused US training is incorporated into 83.3 % of these schools (30 of 36). Focused US training is covered in 83.3 % of schools (30 of 36). US is mostly taught in the anatomy course (38.8 %). US is incorporated in the OMM course in 12 of 36 schools (33.3 %). The majority of respondents feel that US training will make osteopathic students more competitive in the job market (88.9 %) and want more US in their curriculum (86.1 %). The idea that US is useful for a better understanding of the key OMM concepts is believed by 62.9 % of respondents. The major obstacle to the implementation of US in the curriculum is having appropriately trained faculty (86.1 %). The majority of the respondents did not feel that an adequate budget is a handicap to implementing US in the curriculum.

CONCLUSIONS

US is included within the curriculum of all respondents to our survey, a third of whom included US within their OMM curriculum. US is treated as a useful and important skill for future osteopathic physicians. The majority of COMs desire more US training in the curriculum. The main barrier to implementing US in the curriculum is the lack of appropriately trained faculty.

Neurosonology Survey in Europe and Beyond

Purpose  To provide an overview on education, training, practice requirements, and fields of application of neurosonology in Europe and beyond. Materials and Methods  National representatives and experts in neurosonology were surveyed regarding neurosonology requirements and practice in their countries. Descriptive statistics were used to report the data. Results  Between February 1 and March 31, 2023, 42/46 (91.3%) national representatives responded to our questionnaire and the completion rate was 100%. Most countries (71.4%) offer a neurosonology training program during neurology residency, but it is part of the undergraduate medical program only in 30.9%. National certification is available in 47.6% of the countries surveyed and most countries (76.2%) require certification to practice. In 50% of the countries, candidates are assessed by a board examination, while in 26.2% they just need to document their practice. There is no formal accreditation of neurosonology centers in 78.6% of the countries surveyed. Only a few require certified personnel and appropriate equipment. Adequate teaching and research activities are only rarely necessary elements for laboratory accreditation. Conclusion  Our results indicate that there is a substantial need for transnational harmonization of neurosonological standards to guarantee uniformity and quality of performance. This survey will also provide guidance to promote an international accrediting council and create a quality-controlled laboratory network for implementing neurosonology in clinical trials.

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.

Development of a hybrid point-of-care ultrasound curriculum for first year medical students in a rural medical education program: a pilot study

BACKGROUND

The field of point-of-care ultrasound (POCUS) has advanced in recent decades due to the benefits it holds for medical providers. However, aspiring POCUS practitioners require adequate training. Unfortunately, there remains a paucity of resources to deliver this training, particularly in rural and underserved areas. Despite these barriers, calls for POCUS training in undergraduate medical education are growing, and many medical schools now deliver some form of POCUS education. Our program lacked POCUS training; therefore, we developed and implemented a POCUS curriculum for our first-year medical students.

METHODS

We developed a POCUS curriculum for first year medical students in a rural medically underserved region of the United States. To evaluate our course, we measured learning outcomes, self-reported confidence in a variety of POCUS domains, and gathered feedback on the course with a multi-modal approach: an original written pre- and post-test, survey tool, and semi-structured interview protocol, respectively.

RESULTS

Student (n=24) knowledge of POCUS significantly increased (pre-test average score = 55%, post-test average score = 79%, P<0.0001), and the course was well received based on student survey and interview feedback. In addition, students reported increased confidence toward a variety of knowledge and proficiency domains in POCUS use and their future clinical education and practice.

CONCLUSIONS

Despite a lack of consensus in POCUS education, existing literature describes many curricular designs across institutions. We leveraged a combination of student initiatives, online resources, remote collaborations, local volunteers, and faculty development to bring POCUS to our institution in a rural and medically underserved region. Moreover, we demonstrate positive learning and experiential outcomes that may translate to improved outcomes in students' clinical education and practice. Further research is needed to evaluate the psychomotor skills, broader learning outcomes, and clinical performance of students who take part in our POCUS course.

The document has been prepared by the Clinical Ultrasound Working Group and endorsed by the Spanish Society of Internal Medicine.

South African medical interns' perspectives on the use of point of care ultrasound

BACKGROUND

Point of care ultrasound (POCUS) has become such a part of patient care that it is included in undergraduate medical training in many high-income countries. In South Africa, despite the availability of ultrasound units, there is no information on the exposure or training required for medical interns to perform POCUS in their community service year. This study examines interns' self-reported POCUS training and competency, as well as their perceived readiness for their community service year.

METHODS

In this cross-sectional web-based survey, 43 interns were invited to complete a self-administered questionnaire after completing their 6-month decentralised family medicine rotation in 2022.

RESULTS

Thirty complete responses (69% response rate) were included for analysis. Eleven graduates from three medical schools reported undergraduate exposure to POCUS. Ten participants completed formal postgraduate ultrasound training. Eight participants felt confident to independently perform POCUS. Thirteen participants felt adequately prepared for their community service year, 10 of whom had received POCUS training. Nearly all the participants (29 of 30) felt that ultrasound training should be incorporated into both undergraduate and internship training.

CONCLUSION

Medical interns expressed a need for more POCUS training. Most of the studied sample did not feel adequately prepared to perform POCUS independently. The high uptake of additional ultrasound courses highlights the need to include POCUS training. More research is needed to determine the extent and level at which POCUS training should be offered to medical interns in the South African setting.Contribution: This study looks at the perceived need of South African medical interns for formal POCUS training. It highlights a potential gap in training based on the expected clinical requirements of the community service year.

The Rising Tide of Point-of-Care Ultrasound (POCUS) in Medical Education: An Essential Skillset for Undergraduate and Graduate Medical Education

As point-of-care ultrasound (POCUS) becomes an integral component of healthcare, both undergraduate and graduate medical POCUS education is urgently necessary in curricula. Despite the apparent need of POCUS curricula, there remains a lingering question: Are there evidence-based benefits to POCUS training in undergraduate and/or graduate medical education settings? Qualitative review of research was conducted to identify common themes for benefits of POCUS and the requirements and/or characteristics for effective POCUS educational curricula. Results for undergraduate medical education were separated into preclinical and clinical education. In preclinical POCUS education, POCUS education improves anatomy education and physical examination skills for sonographic assessment of abdominal, reproductive, cardiovascular, and renal structures. Further enhancement can be achieved via simulation devices that are generalized ultrasound simulation mannequins, one defined body region such as the abdomen, or local regions of interest such as the femoral triangle. In clinical undergraduate POCUS education, benefits involved greater performance on knowledge tests and general ultrasound competency in emergency medicine, surgical, family medicine, and physical medicine and rehabilitation clerkships. These studies also found improved comprehension of specific POCUS examinations such as those for ultrasound-guided injections, FAST, eFAST, and RUSH. Further integration of POCUS education into graduate medical education was found to successfully improve ultrasound knowledge and competency in both academic and military internal medicine residencies. One limitation of this study is that this article is a review resulting in no specific intervention being introduced. The resultant hypothesis of this systematic review cannot be tested; rather evidence-based recommendations are restricted to the currently available literature within the searched databases. From this review, it was found that the inclusion of a properly integrated POCUS curriculum can result in greater confidence in ultrasound use, increased knowledge of anatomy and basic sciences for various organ systems, improved ultrasound knowledge and performance in clinical clerkships, and offers improved confidence and knowledge in ultrasound during residency.

Point-of-care ultrasonography-An essential skill for medical graduates?

The recent proliferation of point-of-care ultrasonography (POCUS) in the clinical practice of many medical specialties has exposed persistent barriers to education, training and standardisation. Specialist training curriculums are already overwhelming, having grossly insufficient time available for the specialist trainees and for the small number of available trainers alike to incorporate POCUS into postgraduate education. The logical solution to overcome these barriers could be to incorporate basic POCUS education and training into the undergraduate university curriculums, introducing longitudinal integration with other relevant medical sciences. The Australasian Society of Ultrasound in Medicine already has well-established educational programmes in POCUS with standardised assessment of competency, which could potentially offer the basis for symbiosis with the Australian and New Zealand medical schools.

Development and evaluation of a point-of-care ocular ultrasound curriculum for medical students - a proof-of-concept study

BACKGROUND

Point-of-care Ocular Ultrasound (POCOUS) has gained importance in emergency medicine and intensive care in recent years. This work aimed to establish and evaluate a dedicated ultrasound education program for learning POCOUS-specific skills during medical studies at a university hospital.

METHODS

The blended learning-based program (6 teaching units) based on recent scientific publications and recommendations was developed for students in the clinical part of their medical studies. Experts and trainers consisted of physicians from the Ear-Nose-Throat, radiology, ophthalmology and neurology specialties as well as university educational specialists. Lecture notes containing digital video links for preparation was produced as teaching material. In total, 33 students participated in the study. The education program, including the teaching materials, motivation and subjective gain in competency, was evaluated with the aid of a questionnaire (7-point Likert response format). Objective learning success was assessed on the basis of pre- and post-tests. These covered the skill areas: "anatomical basics", "ultrasound basics", "understanding of cross-sectional images", "normal findings" and "pathology recognition".

RESULTS

In the objective assessment of image interpretation, the participants improved significantly (p < 0.001) from pre- to post-test with a large effect size (Cohen's d = 1.78, effect size r = 0.66). The evaluations revealed a high level of satisfaction with the course concept, teaching materials and the tutors. In addition, a high level of motivation was recorded in relation to continuing to study "ultrasound diagnostics" and "ophthalmologic diseases". A significant (p < 0.01) positive gain was also achieved in terms of the subjective assessment of competency. This covers areas such as expertise, sonographic anatomy and performing a POCOUS examination as well as recognizing retinal detachment, globe perforation and increased optic nerve sheath diameter.

CONCLUSION

The results of this feasibility study show that medical students accept and support a POCOUS-specific education program and are able to develop a higher objective and subjective level of competency. Future transfer to other sites and larger groups of participants seems feasible.

Ultrasound skills teaching in UK medical education: A systematic review

BACKGROUND

Sonography is increasingly integrated into medical curricula to prepare students for clinical practice. In 2022, we conducted a systematic review to explore the degree to which ultrasound skill acquisition is incorporated into undergraduate medial education in the United Kingdom.

METHODS

A search of Medline and Embase databases from 2003 to 2022 identified 15 relevant articles. Studies were included if they described ultrasound skills training in UK undergraduate medical education.

FINDINGS

A range of teaching methods were reported including didactic demonstrations, hands-on experience and combinations thereof. Portable machines were more common than cart-based machines, and most demonstrators were ultrasound-trained clinicians. Ultrasound teaching is well received, with improvements in confidence using ultrasound, motivation to learn anatomy and retention of knowledge.

DISCUSSION

Obstacles to integration were noted including training, cost, curriculum time constraints and the issue of incidental pathology. One study demonstrated that anatomists with appropriate training could provide ultrasound teaching, reducing the need for clinicians or sonographers. Costs may be reduced by renting machines or purchasing portable/hand-held devices. Allowing access to machines during student's free time may address scheduling difficulties. A final recommendation is to pre-scan volunteers prior to the teaching session.

CONCLUSION

We have outlined approaches to ultrasound skills teaching and the inherent hurdles to this, as well as potential solutions. This may aid educators wishing to augment their curricula. Although there are relatively few studies from the United Kingdom, there is consensus that students enjoy the incorporation of ultrasound practice and believe it complements existing teaching, especially in a small group setting.

Evaluation of remote radiologist-interpreted point-of-care ultrasound for suspected dengue patients in a primary health care facility in Colombia

BACKGROUND

Early identification of plasma leakage may guide treatment decisions in dengue patients. This study evaluated the value of point-of-care ultrasound (POCUS) to detect plasma leakage and predict hospitalization or referral to a higher level of care in suspected dengue patients under routine conditions at a primary care facility in Colombia.

METHODS

We conducted a cohort study between April 2019 and March 2020 in a primary care hospital in Cali, Colombia. We prospectively included and followed 178 patients who were at least 2 years old with fever of less than 10 days and clinician-suspected dengue. A trained general practitioner performed a standardized POCUS protocol. Images were quality-rated and overread by an expert radiologist, and her results and those of the general practitioner were compared using the Kappa index. Logistic regression was used to identify factors associated with plasma leakage at enrollment and explore its prognostic value regarding hospital admission or referral to a higher level of care.

RESULTS

Half (49.6%) POCUS images were of suitable quality to be interpreted. The proportion of plasma leakage reported by the radiologist was 85.1% (95% CI: 78.6-90.2%) and 47.2% by the study physician (Kappa = 0.25, 95% CI: 0.15-0.35). The most frequent ultrasound findings were ascites (hepatorenal 87.2%, splenorenal 64%, or pelvic 21.8%) and gallbladder wall thickening (10.5%). Plasma leakage was higher in subjects with thrombocytopenia (aOR = 4, 95% CI: 1.3-12.1) and lower in patients 30-59 years old (aOR = 0.1, 95% CI: 0.0-0.4) than in those 18 years old or younger. POCUS evidence of plasma leakage (aOR = 8.2, 95% CI: 2.2-29.9), thrombocytopenia (aOR = 6.3, 95% CI: 2.4-16.0) and pulse pressure (aOR = 1.1, 95% CI: 1.07-1.2) were associated with hospital admission or referral to a higher level of care.

CONCLUSIONS

Ultrasound is useful to detect plasma leakage in primary care and, challenges remain to guarantee high-quality images and diagnostic accuracy, for which a standardized dengue POCUS protocol and training program is needed.

Implementing a Sports Ultrasound Curriculum in Undergraduate Medical Education

ABSTRACT

The utilization of sports ultrasound in the clinical practice of sports medicine physicians is growing rapidly. Simultaneously, ultrasound is being increasingly implemented as a teaching tool in undergraduate medical education. However, a sports ultrasound curriculum for medical students has not been previously described. In this article, we describe methods as well as barriers to implementing a sports ultrasound curriculum at the medical school level. Recommended content for the curriculum also is discussed. While educational goals and resources will vary among institutions, this article may serve as a general roadmap for the creation of a successful curriculum.

Undergraduate ultrasound training: prospective comparison of two different peer assisted course models on national standards

BACKGROUND

A thorough knowledge of sonography is essential in clinical practice. Therefore, sonography training is increasingly incorporated into the medical school curriculum, entailing different course models. The question arises which model is most effective to convey sustained sonographic skills.

METHODS

Two different peer-assisted learning (PAL) sonography course models were developed as part of a clinical prospective study. The course content was based on the national resident curriculum of the German Society for Ultrasound in Medicine (DEGUM). Model A consists of a 10-week course and model B of a two-day compact course. Each model entailed 20 teaching units (TU). A script was used to prepare for each unit. Two modified OSCE exams of the ultrasound skills (max = 50 points per exam) were performed during the last teaching unit to assess the competence level. For subjective self-assessment and model evaluation, a questionnaire with a 7-point Likert scale was employed.

RESULTS

A total of 888 students of the 3rd year participated as part of a voluntary elective in the study (744 in model A and 144 in model B). In the exams, participants in model A (median 43 points) scored significantly higher than those in model B (median 39; p < 0.01). Participants in model A (mean 1.71 points) obtained significantly higher mean competency gain scores in subject knowledge than model B (mean 1.43 points; p < 0.01) participants. All participants were satisfied with the course concept (A: mean 1.68 vs. B: mean 1.78 points; p = 0.05), the teaching materials (A: mean 1.81 vs. B: mean 1.69 points; p = 0.52), and the tutor's didactic skills (A: mean 1.24 vs. B: mean 1.15 points; p < 0.05).

CONCLUSION

These results suggest that sonography-specific competency may be obtained through different course models, with a model stretching over several weeks leading to a higher competence level. Further research should assess the long-term retention of the skills obtained in different models.

Long-Term Effectiveness and Sustainability of Integrating Peer-Assisted Ultrasound Courses into Medical School-A Prospective Study

INTRODUCTION

Ultrasound diagnostics is an important examination method in everyday clinical practice, but student education is often inadequate for acquiring sufficient basic skills. Individual universities have therefore started integrating (extra)curricular training concepts into medical education. This study aimed to evaluate sustainable skills development through participation in peer-assisted ultrasound courses.

METHODS

From 2017, students in the clinical part of medical school could opt for extracurricular peer-assisted ultrasound courses. Depending on the format (10-week course/2-day compact course) these comprised 20 teaching units focusing on abdominal and emergency ultrasonography. Students attending compulsory workshops at the start of their practical year were enrolled in this study, allowing for a comparison between the study group (attended ultrasound course) and the control group (did not attend ultrasound course). Competency from two out of four practical exams (subjects: "aorta", "gallbladder", "kidney" and "lung") was measured, and a theory test on the same subject areas ("pathology recognition") was administered. Additional questions concerned biographical data, subjective competency assessment (7-point Likert scale), and "attitude to ultrasound training in the curriculum".

RESULTS

Analysis included 302 participants in total. Ultrasound courses had been attended on average 2.5 years earlier (10-week course) and 12 months earlier (2-day compact course), respectively. The study group (n = 141) achieved significantly better results than the control group (n = 161) in the long-term follow-up. This applies both to practical exams (p < 0.01) and theory tests (p < 0.01). After course attendance, participants reported a significantly higher subjective assessment of theoretical (p < 0.01) and practical (p < 0.01) ultrasound skills.

CONCLUSIONS

Peer-assisted ultrasound courses can sustainably increase both theoretical and practical competency of medical students. This highlights the potential and need for standardised implementation of ultrasound courses in the medical education curriculum.

Ultrasound Evaluation of Knee Osteoarthritis

While radiographs and magnetic resonance imaging (MRI) have long been used in the assessment of osteoarthritis (OA), ultrasound imaging has been rapidly accepted by musculoskeletal providers in both the assessment and treatment of OA. A limiting factor in the use of ultrasound is the proper training required by the user for results to be reliable and reproducible. A standardized ultrasound protocol can potentially address this limiting factor. The critical information to consider in a standardized protocol include proper patient positioning, probe alignment, probe orientation, and identification of the appropriate anatomic landmarks. The outlined protocol considers these factors with the purpose of providing a step-by-step method to assess and monitor knee OA.

Recommendations for POCUS Curriculum in Canadian Undergraduate Medical Education: Consensus from the Inaugural Seguin Canadian POCUS Education Conference

Point of care ultrasound (POCUS) in Canadian undergraduate medical education (UGME) is limited. To address this paucity, the inaugural Seguin Canadian POCUS Education Conference hosted 14 of the 17 Canadian medical schools to develop a list of recommendations for POCUS education in Canadian UGME. Attending schools were divided into delegations consisting of a pre-clerkship student, a clerkship student and a staff physician. Recommendations were developed via a modified consensus development panel. Delegations submitted school-specific POCUS education summary documents for roundtable discussions, which yielded an initial set of recommendations. These were then summarized in a large group setting and voted upon for adoption with an a priori agreement threshold of 80%. Conference attendees developed 14 recommendations which 87% of participants agreed to adopt. Conference recommendations reflect the opinions of Canadian trainees and POCUS education experts thus serving as a framework for UGME POCUS education in Canada.

Virtual Supervision of Third Year Medical Students Using Handheld POCUS Devices and Cloud-based Image Archiving Provides Opportunity for Feedback and Skill Improvement

Background : Feedback on Point of Care Ultrasound (POCUS) skills is essential for skill development. Providing feedback can be difficult in a large province with several distributed medical education sites. Use of handheld POCUS devices and a cloud-based image archiving enables virtual supervision. We evaluated the quality of uploaded images as well as feedback provided to students. Methods: Volunteer third year students were given access to handheld POCUS devices at various training sites. Students were encouraged to upload educational POCUS scans to their accounts where they would then receive feedback from faculty. Subsequently, images that met inclusion criteria were randomized and reviewed by a blinded expert using a global rating scale. Feedback was also analyzed. Finally, students completed a questionnaire on their technology-enhanced POCUS learning experience. Results: An independent-sampled t-test comparing mean ratings for initial images submitted prior to any feedback with those submitted after three rounds of feedback showed significant effect on image scores (2.60 vs 3.50, p = .040, d = .93). Feedback included 4 performance domains (indications, image generation, interpretation, and integration). Students found the technology easy to use and felt feedback was tailored to their learning needs. Conclusions: We observed that virtual feedback provided to medical students through a cloud-based work platform can be effective for enhancing POCUS skills.

Point-of-Care Ultrasonography in a Pulmonary Hypertension Clinic: A Randomized Pilot Study

Pulmonary arterial hypertension (PAH) is a rare condition with the potential to progress to right heart failure. Point-of-Care Ultrasonography (POCUS), used and interpreted in real time at the bedside to further the cardiopulmonary assessment, has the potential to improve the longitudinal care of PAH patients in the ambulatory setting. Patients from PAH clinics at two academic medical centers were randomized to either a POCUS assessment cohort or non-POCUS standard care (ClinicalTrials.gov identifier NCT05332847). The POCUS group received blinded heart, lung, and vascular ultrasound assessments. Thirty-six patients were randomized to the study and followed over time. Mean age was 65 in both groups and majority female (76.5% and 88.9% females in POCUS and control, respectively). Median time for POCUS assessment was 11 min (range 8-16). There were significantly more changes in management in the POCUS group than control (73% vs. 27%, p-value < 0.001). Multivariate analysis revealed that management changes were more likely to occur with a POCUS assessment, with an odds ratio (OR) of 12 when POCUS was added to physical exam vs. OR of 4.6 compared to physical examination alone (p < 0.001). POCUS in the PAH clinic is feasible and, when combined with physical examination, increases the number of findings and results in changes in management without significantly prolonging visit encounters. POCUS may help support clinical evaluation and decision making in ambulatory PAH clinics.

Lessons Learned from POCUS Instruction in Undergraduate Medicine During the COVID-19 Pandemic

Point of care Ultrasound (POCUS) has been adopted into clinical practice across many fields of medicine. Undergraduate medical education programs have recognized the need to incorporate POCUS training into their curricula, traditionally done in small groups with in-person sessions. This method is resource intensive and requires sufficient equipment and expertise. These requirements are often cited as barriers for implementation. During the Coronavirus Disease 2019 (COVID-19) pandemic, POCUS education was required to adapt to physical distancing regulations, giving rise to novel teaching methods for POCUS. This article outlines the implementation of a POCUS teaching session before and during the pandemic. It describes how these innovations can scale POCUS teaching and overcome barriers moving forward. A flipped classroom model was implemented for all learners. Learners were given an introductory POCUS module before the scheduled in-person or virtual teaching session. Sixty-nine learners participated in conventional in-person teaching, while twenty-two learners participated in virtual teaching following the pandemic-related restrictions. Learners completed a written test before and following the teaching. In-person learners were assessed using an objective structured assessment of ultrasound skills (OSAUS) pre- and post-learning sessions. A follow-up survey was conducted three years after the teaching sessions were completed. Both in-person and virtual groups demonstrated statistically significant improvement in knowledge scores (p <0.0001). Both groups had similar post-test learning scores (74.2 ± 13.6% vs. 71.8 ± 14.5 %, respectively). On follow-up questionnaires, respondents indicate that they found our online and in-person modes of teaching helpful during their residency. POCUS education continues to face a variety of barriers, including limitations in infrastructure and expertise. This study describes an adapted POCUS teaching model that is scalable, uses minimal infrastructure and retains the interactivity of conventional small-group POCUS teaching. This program can serve as a blueprint for other institutions offering POCUS teaching, especially when conventional teaching methods are limited.

A web-based self-learning system for ultrasound-guided vascular access

Ultrasound-guided vascular access is practiced widely. Optimal educational methods have not yet been established. We hypothesized that a step-by-step web-based learning system is effective for self-learning. In this study, we examined the potential of this system as a self-learning tool. This was an observational study at a single institution. Participants included residents, who were self-educated through the web-based system. Skill proficiency was measured after self-learning. The primary outcome was the extent to which self-learning enabled residents to acquire proficiency in the basic skills of ultrasound-guided vascular access: needle visualization, hand-eye coordination, and avoiding posterior wall penetration. A secondary outcome was the time required to achieve proficiency. Thirty-nine residents were enrolled in this study. Eleven residents (28%) passed the first skill assessment test. There was no significant difference in the number of days that the web-based system was accessed, the total number of screen views, or the total learning time between participants who passed and those who failed the first test. Skill assessment scores between those who passed and those who failed the first test were different, especially the score for hand-eye coordination, and the number of posterior wall penetrations. Self-learning with a web-based system enabled 28% of residents to pass the first skill assessment test. The remaining 72% failed the first skill assessment test but continued to learn using the web-based system and eventually passed the test. Hence, the web-based system needed formative testing to function as a self-learning system. Simulation education for vascular access is expected to increase in educational content and methods. Self-learning through a web-based learning system is a leading candidate for this growth.
