The role for peer-assisted ultrasound teaching in medical school

Comparing Peer-Taught Student Tutors to Faculty-Taught Student Tutors in Educating Medical Students on Musculoskeletal Ultrasound

INTRODUCTION

In recent years, medical education has witnessed a shift in the integration of ultrasound into the preclinical years of medical school. Given the exponential increase in accessibility to ultrasound technology, students now have the opportunity to create peer learning groups in which ultrasound concepts can be taught from peer to peer, empowering students to work together to integrate ultrasound concepts early in their preclinical education. This project investigates the efficacy of peer-taught student tutors (PTSTs) in imparting the fundamentals of basic ultrasound techniques to first-year medical students in the setting of identifying and labeling upper extremity musculoskeletal (MSK) anatomy.  Methods: First-year medical students were instructed to identify volar forearm structures with an ultrasound probe. Students and instructors were given access to an ultrasound probe, ultrasound gel, an iPad, and a standardized patient. Students were taught either by an ultrasound instructor (UI) or PTST. After a hands-on demonstration by a UI or PTST, participating students were told to take screenshots and label their images as accurately as possible, identifying the aforementioned volar structures on a standardized patient without any feedback. The labeled screenshot images of volar structures were graded based on the ability to clearly visualize the intended structures.  Results: The results of this study compare the efficacy of PTSTs as educators of basic sonographic identification techniques with that of UI faculty members. A chi-square analysis was performed between the images obtained by the UI and PTST students, and there was no statistically significant difference in identification accuracy between the groups (p = 0.7538, 0.1977, 0.1812, 0.301). When using the Mann-Whitney U rank test, there remained no statistically significant difference between the accuracy of the students taught by STs compared to students taught by UIs (p = 0.7744, 0.09538, 0.07547, 0.1846). Another finding showed that students belonging to both teaching groups were generally not able to infer the pathology of volar wrist structures when given pathology identification questions regarding upper extremity ultrasound. Using chi-square with Yates correction, there is no sufficient evidence to justify an association between the ability to answer pathology-based ultrasound questions and instructor type (p = p = 0.6299, 0.8725).

CONCLUSIONS

This study supports the interpretation that the capability of first-year medical students to learn novice MSK sonographic identification is independent of whether the educator is a PTST or UI. This interpretation reveals a promising avenue toward the integration of the fundamentals of ultrasound identification early in medical education with little to no concern for the exhaustion of institutional resources. Along with the other well-documented benefits of the utilization of STs in medical school, a peer tutoring system centered on ultrasound skills designed in the way this study describes can be an effective, resource-sparing system that enhances medical students' sonographic capabilities early in their preclinical years.

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.

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.

The Effectiveness of Student-Led Musculoskeletal and Vascular Ultrasound Workshops at a Single Institution: A Retrospective Survey Analysis

Introduction Point-of-care ultrasound (POCUS) is a rapidly evolving field of diagnostic medicine as its low cost, portability, and versatility have made handheld ultrasound (US) probes an invaluable tool for many modern physicians. Despite US's benefits as a bedside evaluative tool, many medical schools have not integrated POCUS into their pre-clerkship medical education due to a lack of equipment and faculty. The first objective of our study was to determine whether student tutors (STs) would be effective resources to teach musculoskeletal (MSK) and vascular US to preclinical medical students. The second objective of our study was to determine whether students who previously attended ST-run MSK US workshops perform better in vascular US than those who did not. Methods Six POCUS workshops were led by STs after approval from experienced US faculty. These included US workshops on gastrointestinal structures, forearm structures, joint structures, basic echocardiography, and US-guided IV access. We collected data from two of our six workshops. We developed surveys to gauge the confidence and ability of students to perform US after an MSK workshop and US-guided IV access workshop led by STs. We also measured students' US abilities and collected student feedback after our US-guided IV access workshop. We evaluated students' US competency in US-guided IV access via their ability to correctly position the US probe, angle the needle of insertion, move the probe with the needle, and access the vein based on the accuracy of the movements. We divided student results into two groups: students who previously attended the MSK workshop before attending the US-guided IV access workshop and students who did not attend the MSK workshop before attending the US-guided IV access workshop. We used averages, frequencies, and two-tailed t-tests to analyze the survey responses and US-guided IV access skill assessments. Results Fifty percent of first- and second-year surveyed students "agreed," and 32.4% "strongly agreed" that they felt confident using US after an ST-run MSK workshop. About 29.4% of surveyed students "agreed" and 41.2% "strongly agreed" that they felt comfortable explaining basic US concepts, such as proper probe positioning and echogenicity. The group of students who attended the MSK workshop prior to the peripheral IV workshop scored similarly to the students who did not attend the MSK workshop (14.33±1.03 versus 14.20±0.84 points). Both groups of students had an average of over 94% accuracy in technique, positioning, angling, moving the US probe, and achieving US-guided venous access after being taught by STs. Qualitative surveying noted positive student feedback, such as "Teacher was great at guiding us through the procedure." Survey responses also included suggestions on adding and diversifying equipment, such as "[It would be useful to have a] different type of needle to see the difference on ultrasound." Conclusion Based on the high percentages of accuracy and confidence, we found that STs were effective resources to teach MSK and vascular POCUS and that students who attended previous MSK ST-run US workshops had stronger vascular US ability over time compared to those who did not. Our data support the use of STs as US educational resources, especially in institutions without an existing pre-clerkship US curriculum and limited US resources.

Using tele-ultrasound to teach medical students: A randomised control equivalence study

Objectives

Undergraduate ultrasound education is becoming increasingly important, but its expansion is limited by time, space and the availability of trained faculty. In order to validate an alternative and more accessible teaching model, our aim was to assess whether combining teleguidance and peer-assisted learning to teach ultrasound is as effective as traditional in-person methods.

Methods

Peer instructors taught 47 second-year medical students ocular ultrasound via either teleguidance or traditional in-person methods. Proficiency was assessed using a multiple-choice knowledge test and objective structured clinical examination (OSCE). Confidence, overall experience, and experience with a peer instructor were measured using a 5-point Likert scale. Two one-sided t-tests were used to measure equivalency between the two groups. The null hypothesis that the two groups were not different was rejected when P < 0.05.

Results

The teleguidance group performed as well as the traditional in-person group in terms of knowledge change, confidence change, OSCE time and OSCE score (p = 0.011, p = 0.006, p = 0.005 and  = 0.004, respectively, indicating the two groups are statistically equivalent). The teleguidance group rated the experience highly overall (4.06/5), but less than the traditional group (4.47/5; P = 0.448, indicating statistical difference). Peer instruction was rated 4.35/5 overall.

Conclusion

Peer-instructed teleguidance was equivalent to in-person instruction with respect to knowledge change, confidence gain and OSCE performance in basic ocular ultrasound.

How confident are UK radiographers at performing paediatric computed tomography trauma scans?

INTRODUCTION

Approximately 45% of paediatric deaths in the United Kingdom (UK) were as a result of trauma. Computed tomography (CT) provides time efficient and accurate diagnosis, increasing chances of survival. Whilst use of CT in evaluating paediatric trauma has been invaluable it carries significant radiation risks, largely because children have greater radiation sensitivity than adults. Although national paediatric trauma workload in the UK is proportionately low, the majority of paediatric patients are conveyed to hospitals which predominantly undertake CT scans on adult patients. This research aimed to determine the confidence levels of radiographers when performing paediatric CT trauma scans in three public hospitals in the UK, and whether a teaching intervention improved their perceived self-confidence.

METHODS

Individual questionnaires containing eight qualitative and quantitative questions were used to ascertain radiographers' perceived confidence levels. A teaching intervention was developed based on responses. A post-intervention questionnaire was used to determine whether radiographers' confidence levels had improved.

RESULTS

Radiographers (n = 45) reported a mean confidence score of 5.6 (standard deviation 2.2) and 8.0 (standard deviation 1.7) scanning paediatric trauma patients pre- and post-intervention respectively. A paired two group t-test found this difference to be statistically significant at p < .00001. Radiographers reported several factors which negatively influenced confidence levels, including limited experience and postgraduate education.

CONCLUSION

Radiographers reported to be less confident scanning paediatric CT trauma patients compared to adults, pre- and post-intervention, however this research does not clarify whether this is as a result of an increase in competence. Further research regarding this concept warrants investigation.

IMPLICATIONS FOR PRACTICE

Results suggest further training based on negative factors reported by radiographers can increase confidence when performing this type of scan, assisting radiographers in optimising paediatric patient doses.

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.

Does the clinical experience of a tutor influence how students learn extended focused assessment with sonography for trauma: A randomized controlled trial

BACKGROUND

Extended focused assessment with sonography for trauma (eFAST) is now an essential part of the primary survey of an emergency patient. The discrepancy between an increasing number of medical students and growing clinical commitments of lecturers is a major challenge in student teaching that needs to be resolved. The practice of using peers in the clinical education of medical students is a well-established tradition and commonly practiced but lacks definition in its implementation. Therefore, we aimed to investigate whether the level of experience of the tutor affects the effectiveness of learning among students using eFAST during a clinical scenario.

METHODS

A prospective randomized single-blinded controlled trial, where 168 medical students in the eighth semester were randomized into control and intervention groups. The control group received the 4-h standard ultrasound (US) tutorial from various resident doctors. All residents were at least stage-1-certified in ultrasound. The intervention group received the tutorial from trained peer teachers (TPTs). These TPTs were medical students who were qualified to teach the procedure. All students received an initial tutorial on basic ultrasound principles and a final lecture on recognizing pathological images. Students completed basic questionnaires requesting pre-existing US experience, theoretical and clinical application questions based on eFAST one day later and at the end of the semester. Students also completed a 6-min OSCE (Objective-Structured-Clinical-Exam) station involving clinical emergency scenarios.

RESULTS

Eighty-five percent of participants had no previous eFAST experience. Early and later evaluation of the participants show no significant differences between both groups regarding the theoretical and the clinical application examinations, except the early phase OSCE results, which was not repeated in the late-stage results.

CONCLUSIONS

Peer-teaching can be utilized to teach practical skills such as eFAST without a loss of clinical application skills. This relieves the burden of removing doctors from patient care situations and maintains teaching standards.

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.

Comparing the Effectiveness and Image Quality of Musculoskeletal Ultrasound of First-Year Medical Students After Training by Student Tutors Versus Ultrasound Instructors: A Pilot Study

Background

Ultrasound is a vital part in many medical schools’ curriculum. Although there is strong support for the use of student tutors (STs), there is a lack in gauging their effectiveness with more difficult organ systems such as the musculoskeletal (MSK) system. We aim to determine the effectiveness of using STs versus expert ultrasound instructors (UIs) when teaching MSK ultrasound.

Methodology

Medical students were recruited to participate in an MSK workshop to identify superficial volar arm structures (radial nerve, radial artery, median nerve, ulnar artery, ulnar nerve) using Butterfly iQ. In total, 14 participants were taught by STs and 10 participants were taught by UIs. Participants imaged the five structures and answered surveys gauging their confidence via five-point Likert scales.

Results

There was no significant difference in confidence or identification accuracy for all five structures between the two groups. However, there was a significant difference in confidence in the understanding of basic ultrasound concepts in favor of the UI group (p < 0.05). A greater number of students were more confident in identifying all five structures when taught by STs, but more students correctly identified the structures when taught by UIs.

Conclusions

The results on confidence could be due to positive peer perception. Both groups scored relatively high in their identification accuracies, promoting the successful use of STs. The successful use of STs in teaching MSK ultrasound opens the possibility to developing peer-led ultrasound curriculum on more complex ultrasound topics in the future.

Development of a Point-of-Care Ultrasound Track for Internal Medicine Residents

BACKGROUND

Point-of-care ultrasound (POCUS) training has been increasing among internal medicine (IM) residency programs, but few programs can provide longitudinal training due to barriers such as lack of trained faculty.

AIM

Describe the development of a longitudinal POCUS track for IM residents using local and external resources, including a national POCUS certificate program.

SETTING

University-based IM residency program affiliated with a public and veterans affairs hospital.

PARTICIPANTS

Twelve IM residents from 2018 to 2021.

PROGRAM DESCRIPTION

Residents complete a national POCUS certificate program by attending live courses and completing online modules, an image portfolio, and final knowledge/skills assessments. Locally, residents participate in 1-month procedure and diagnostic POCUS rotations and provide peer-to-peer POCUS teaching of residents and medical students.

PROGRAM EVALUATION

The POCUS track increased residents' use and comfort with diagnostic and procedural applications. All residents rated being satisfied or very satisfied with the track and would recommend it to prospective applicants (100%). The most commonly reported barriers to utilizing POCUS per residents were time constraints (83%), lack of available ultrasound equipment (83%), and lack of trained faculty (58%).

DISCUSSION

IM residency programs with limited faculty expertise in POCUS can leverage external resources to provide longitudinal POCUS training to its residents.

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.

Impact of Peer-Assisted Learning on Ultrasound

PURPOSE

The aim of this study was to understand how peer-assisted learning (PAL) could be utilized by physician assistant (PA) students in an ultrasound student interest group (USIG) as a means of developing cognitive confidence and practical competence with the imaging modality.

METHODS

An observational study that included 3 USIG workshops was designed. Pre- and postworkshop surveys were administered. All first-year PA students, regardless of participation in the USIG workshops, were asked to complete the voluntary and anonymous surveys.

RESULTS

A statistically significant difference between those who attended at least one workshop and those who did not attend any workshops on their postworkshop scores (p = 0.02) was seen. There was a statistically significant association between the number of workshops attended and the postworkshop difference (p = 0.03).

CONCLUSION

Results show that, in the context of social cognitive theory, PAL is an efficacious learning modality that enhances learner and tutor performance in ultrasound.

Integrating Basic and Clinical Sciences Using Point-of-Care Renal Ultrasound for Preclerkship Education

INTRODUCTION

Point-of-care ultrasound (POCUS) is a valuable asset in bedside clinical care. Undergraduate medical education is increasingly using POCUS as an adjunct tool for teaching anatomy, pathophysiology, and physical exam in an integrated manner. Many medical schools teach content in an organ systems-based format in the preclerkship years. POCUS teaching can be very effectively tailored to specific organ systems. Though pilot curricula for generalized ultrasound education exist, few teach organ systems-based content using POCUS. To address this gap, we designed and implemented an integrated POCUS module to supplement anatomy, pathophysiology, and physical exam teaching in the renal course.

METHODS

The module consisted of (1) a 30-minute didactic lecture introducing students to renal ultrasound technique and image interpretation and (2) a practical hands-on skills session. Pre- and postmodule surveys assessed the efficacy and impact of the curriculum.

RESULTS

A total of 31 first-year medical students completed the POCUS renal curriculum. A majority reported that the module positively affected their understanding of renal pathophysiology and the physical exam. They also reported increased confidence in using POCUS to detect renal pathology and make clinical decisions.

DISCUSSION

It was feasible to implement a POCUS curriculum to supplement integrated teaching of renal system concepts in the first year of medical school, and students found POCUS teaching valuable. POCUS provides educators with another tool to integrate basic and clinical sciences with hands-on relevant clinical skills practice in early medical school years.

A narrative literature review: Growing the workforce through increased fieldwork capacity in genetic counseling training programs

In response to mounting concerns regarding a perceived shortage of genetic counselors, the Genetic Counselor Workforce Working Group (WFWG) was established in 2013 to identify barriers to growth of the genetic counseling workforce. After completing a workforce analysis and confirming a shortage, the WFWG convened a strategic planning session in 2017 to identify goals and strategies that would increase the number of certified counselors to meet the current and future workforce demands and ensure access to genetic counselor services. Subcommittees were formed and charged with achieving assigned goals; one such subcommittee included a curriculum working group to build a dynamic and effective educational infrastructure to increase the number of genetic counselors graduated from accredited training program. This paper reports of progress of the WFWG Curriculum Subcommittee toward achieving this goal through a narrative literature review that identifies innovative education methods that help to increase capacity of fieldwork training, both in genetic counseling training programs and in other health professions. Of the five thematic areas identified in this study, four are analyzed for insight into building clinical capacity: systems/infrastructure, rotation structure/models, skill building, and novel techniques. While additional studies are needed to establish best practices in these thematic areas, there are several take-aways that training programs can begin to utilize as they look to expand training opportunities. While growth of the genetic counseling workforce will continue to be a long-term issue, programs should begin to think creatively and innovatively about how to reach beyond traditional fieldwork training formats to build capacity. The strategies explored in this paper offer feasible and untapped solutions that can help support efforts to establish a sustainable genetic counseling workforce.

Integration of ultrasound in medical School: Effects on Physical Examination Skills of Undergraduates

INTRODUCTION

Ultrasound (US) imaging has rapidly increased its application in almost every medical field. Many universities worldwide provide teaching of US for undergraduates in their curricula. Emerging evidence is supporting the use of ultrasonography to improve also non-US skills and knowledge of medical students.

OBJECTIVES

The purpose of this review is to understand if the integration of US lessons into medical students' curriculum improves their learning of physical examination and enhances their skills when performing it.

METHODS

We performed a systematic review of literature by searching three electronic medical databases. We included studies of any level of evidence published in peer-reviewed journals. Evaluated data were extracted using the PICO framework and critically analyzed. PRISMA guidelines were applied; we excluded all the articles evaluated with serious risk of bias and/or low methodological quality.

RESULTS

We included 15 articles, accounting for more than 1643 medical students involved from five different countries and 14 various academical institutions. Eight out of nine studies (88.9%) reported an improvement of practical physical examination scores by students exposed to ultrasound lectures. Eleven out of eleven studies (100%), which administered self-assessment questionnaires, reported strong agreement among students that ultrasound lectures helped them learning and understanding the physical exam and improved their confidence and skills.

CONCLUSIONS

Increasing evidence shows that incorporating ultrasound in medical students' curriculum might improve their ability and confidence when learning and performing a physical exam. This significant tendency needs to be corroborated at a deeper level by further studies.

Team-based learning for teaching musculoskeletal ultrasound skills: a prospective randomised trial

OBJECTIVE

The aim of this prospective randomised trial was to assess the impact of the team-based learning approach on basic musculoskeletal ultrasound skills in comparison to both peer-assisted and conventional teaching and to examine the influence of gender and learning style on learning outcomes.

METHODS

In this prospective randomised trial, we randomly assigned 88 students to 3 groups: team-based learning (n = 19), peer-assisted learning (n = 36) and conventional teaching (n = 33). Pre-existing knowledge was assessed using a multiple-choice (MC) exam. Student performance after completing the course was measured using an Objective Structured Clinical Examination (OSCE) and a second MC exam. Students were asked to complete Kolb's Learning Style Inventory and to evaluate the course.

RESULTS

There was a significant gain in theoretical knowledge for all students (p < 0.001). The team-based learning groups' performance proved to be significantly superior on the OSCE (p = 0.001). As gender had no significant effect on practical or theoretical performance, learning style was linked to differences in the practical outcome. An evaluation showed overall satisfaction with the course and with the respective teaching methods.

CONCLUSION

Team-based learning proved to be superior to peer-assisted and conventional teaching of musculoskeletal ultrasound skills.

Short- and Long-Term Effects on Knowledge, Skills, and Attitudes About a Sonography Training Concept for Medical Students

Objectives:

Worldwide medical schools that provide sonography training appear to be very heterogeneous in their offerings. A medical school has developed a training program with limited resources, which used a peer teaching method, to provide sonography training. The implemented courses consist of a voluntary laboratory practical and a required didactic seminar.

Methods:

To analyze this concept, the effects on knowledge, skills, and attitudes were examined by using surveys, multiple-choice tests, and practical tests.

Results:

The teaching concept demonstrated a positive effect on theoretical knowledge, practical skills, and attitudes. Nevertheless, some practical skills such as conducting gallbladder sonography deteriorated over the time of the study.

Discussion:

The peer-teaching approach with well-trained students as instructors and tutorials in smaller groups appeared to be a key element for success. This cohort study underlines the need to provide both theoretical and practical mandatory training.

Conclusion:

Peer teaching may be a cost-effective way to teach sonography skills to medical students during their training.

Novel Approach to Introducing an Ultrasonography Curriculum With Limited Instructor Resources

Context

Ultrasonography is becoming more prevalent in clinical practice, but medical schools looking to implement preclinical training are limited by financial and faculty resources.

Objective

To design a single-instructor model to save faculty resources and to determine whether this model is effective at teaching ultrasonography to preclinical medical students.

Methods

This single-instructor model included 3 components: (1) flipped classroom, where students watched an online lecture covering examination techniques; (2) in-person scanning sessions, where students scanned each other after the instructor went through lecture content and pathologic images, a video camera to show probe placement and examination technique, and a live feed from an ultrasonography demonstration; and (3) feedback on written examination questions and course evaluations.

Results

When compared with a traditional ultrasonography curriculum, which requires approximately 600 instruction hours annually, this program required 96 hours. Students reported appreciation of exposure to ultrasonography but expressed desire for smaller group sizes and greater individual instruction. Students performed well on written test questions, with the first-year class answering 88% correctly and the second-year class answering 90.6% correctly.

Conclusions

Although this educational format was used successfully to teach introductory ultrasonography to preclinical students, feedback suggested that students would prefer more individual instruction. The authors look toward implementing a peer-instructor format, forming smaller laboratory groups, and improving skill assessment.

[Ultrasound training in emergency and intensive care medicine : Integration already in medical school?]

Ultrasound is an important diagnostic tool especially in emergency and intensive care medicine. It is always available at the bedside and shortens time to diagnosis. Many specialties have integrated ultrasound into diagnostic algorithms as part of the extended physical exam. Numerous differential diagnoses can be easily excluded using point-of-care ultrasound and therefore adequate treatment is initiated faster. Emergency or focused ultrasound is therefore of outstanding relevance to any emergency or critical care physician. Integration into medical school curricula is becoming more common tough no nationwide standards are in place yet.

Point-of-Care Ultrasonography Integration in Undergraduate Medical Education: A Student-Driven Approach

Background

The importance of medical ultrasonography (US) is well established, but given an already dense curriculum, integration of US into preclinical training can be difficult. Although there is no clear consensus on the best practice for integrating US into medical school curricula, growing student interest in US training demands investigation of potential solutions.

Objective

To investigate whether US integration through peer-assisted learning (PAL) and extracurricular activities during preclinical training is perceived to be valuable by student participants.

Methods

First- and second-year students at the West Virginia School of Osteopathic Medicine (WVSOM) were invited via email to attend 4 monthly PAL extracurricular US sessions on the following point-of-care US topics: (1) basic lung examination to assess pleural sliding, (2) extended focused assessment with sonography for trauma, (3) right upper quadrant biliary examination, and (4) US-guided central venous catheter placement. A brief survey using Likert-style questions inquired about participants' level of agreement with whether the given session was appropriately complex, increased comfort with US, was informative and interactive, and improved confidence in identifying anatomic structures (sessions 2 and 3 only). A final question asked participants whether they would attend more extracurricular US sessions.

Results

Fifty-eight students (36 unique students) attended the peer-led sessions. Of the 58 students, 50 responded to the survey for a response rate of 86.2%. Responses were overwhelmingly positive. All respondents strongly agreed or agreed that these sessions improved their confidence in identifying anatomic structures using US, and 49 (98%) strongly agreed or agreed that they would attend more US sessions.

Conclusion

Respondents strongly endorsed the peer-led US sessions, which has facilitated the formal integration of an elective US course at WVSOM. The peer-led sessions introduced at WVSOM could provide the framework and motivation for similar courses at osteopathic medical schools across the country.

A Prospective Evaluation of Point of Care Ultrasound Teaching in Switzerland

Context:

As the utility of point-of-care ultrasound (POCUS) continues to expand in the medical field, there is a need for effective educational methods. In Switzerland, medical education follows the European model and lasts 6 years, focusing on preclinical training during the first 2 years. No previous studies have evaluated the optimal time for teaching ultrasound in European medical education.

Aims:

The aim of this study is to provide ultrasound training to medical students in Switzerland at varying times during their clinical training to determine if the level of training plays a role in their ability to comprehend and to apply basic POCUS skills.

Methods:

We performed an observational study utilizing a convenience sample of Swiss medical students between July 11, 2016 and August 6, 2016. They were taught a 2-day POCUS course by five American-trained 1^st-year medical students. Following this course, students were evaluated with written and clinical examination.

Results:

100 Swiss medical students were enrolled in the study. A total of 59 of these students were early clinical students, and 41 students were late clinical students. A two-tailed t-test was performed and demonstrated that the late clinical students performed better than the early clinical students on the written assessment; however, no difference was found in clinical skill.

Conclusion:

Our data suggest that Swiss medical students can learn and perform POCUS after a 2-day instructional taught by trained 1^st-year American medical students. No difference was found between students in early clinical training and late clinical training for the ability to perform POCUS.

First Year Medical Student Peer Nominations of Professionalism: A Methodological Detective Story about Making Sense of Non-Sense

This article explores the assessment of professionalism within a cohort of medical students during a sequential 13-week medical school histology and anatomy course. Across seven data points, students were asked to identify a professionalism role model from amongst their peers and to score Likert-structured rationales for their decision. Based on density scores, an initial social network analysis identified six peer-nomination "stars." However, analysis of these stars revealed considerable variability and random-like "noise" in both the nomination and explanation data sets. Subsequent analyses of both data sets explored the possibility of underlying patterns in this noise using tests of reliability, principal components factor analysis, and fixed-effects regression analysis. These explorations revealed the presence of two dimensions (professional vs. supportive) in how students sought to explain their nomination decisions. Although data variability remained quite high, significantly less variability was present in the professional than in the supportive dimension, suggesting that academic helpfulness rationales are both empirically distinct and more mutable than rationales grounded in professionalism-related factors. In addition, data showed that the greater the stability in one's choice of a professionalism role model nomination over the T1-T7 data periods, the more stable one's reasons for that nomination-both for professionalism and supportive dimensions. Results indicate that while peer assessment of professionalism by first-year medical students may not be very reliable, students can differentiate between more personal and professional factors, even at this early stage in their professional development. Formal instruction within the pre-clinical curriculum should recognize and address this distinction. Anat Sci Educ. © 2018 American Association of Anatomists.

Ultrasonography in Undergraduate Medical Education: A Systematic Review

OBJECTIVES

The purpose of this study was to conduct a systematic review of the evidence of educational outcomes associated with teaching ultrasonography (US) to medical students.

METHODS

A review of databases through 2016 was conducted for research studies that reported data on teaching US to medical students. Each title and abstract were reviewed by teams of 2 independent abstractors to determine whether the article would be ordered for full-text review and subsequently by 2 independent authors for inclusion. Data were abstracted with a form developed a priori by the authors.

RESULTS

Ninety-five relevant unique articles were included (of 6936 identified in the databases). Survey data showed that students enjoyed the US courses and desired more US training. Of the studies that assessed US-related knowledge and skill, most of the results were either positive (16 of 25 for knowledge and 24 of 58 for skill) or lacked a control (8 of 25 for knowledge and 27 of 58 for skill). The limited evidence (14 of 95 studies) of the effect of US training on non-US knowledge and skill (eg, anatomy knowledge or physical examination skill) was mixed.

CONCLUSIONS

There is ample evidence that students can learn US knowledge and skills and that they enjoy and want US training in medical school. The evidence for the effect of US on external outcomes is limited, and there is insufficient evidence to recommend it for this purpose at this time.
