Describing Ultrasound Skills Teaching by Near-Peer and Faculty Tutors Using Cognitive Apprenticeship

Quality assessment of a training program for undergraduate sonography peer tutors: paving the future way for peer-assisted learning in medical ultrasound education

Introduction

Peer tutoring has been increasingly used to support university sonography teaching, necessitating well-qualified tutors. This study aims to evaluate the quality of a training program for sonography peer tutors developed and implemented at a university hospital.

Materials and methods

A training program consisting of 11 modules was developed and subsequently evaluated for success with two subjective and two objective assessments of peer-tutoring quality. The two subjective assessments measured subjective scores of the peer tutors' specialist and didactic skills using a Likert scale (1 = very low; 7 = very high) from the perspective of the individuals the peer tutor taught (assessment 1) and from the peer tutors themselves (assessment 2). The peer tutors also rated the training concept itself. The objective assessments evaluated the peer tutors' specialist skills with a theoretical test (assessment 3) and a practical examination (assessment 4). Data collection for assessment 1 began in 2017, while data for assessments 2 to 4 were collected from 2021 to 2024.

Results

A total of 2,980 data sets for assessment 1, 92 data sets for 2, 44 data sets for assessment 3, and 147 data sets for assessment 4 were included in the analysis. Peer tutors scored highly positively on assessments 1 [6.6 ± 0.63 scale points (SP)] and 2 (5.53 ± 0.63 SP), and these results remained consistently high throughout the semesters. Assessments 3 (74.7 ± 7.9%) and 4 (85.6 ± 10.5%) also showed strongly positive values that remained constant over time. Assessment 1 results were significantly higher than the others (p < 0.01.), while no significant differences were found between assessments 2, 3, and 4.

Conclusion

The data indicate that the training concept developed established and maintained high-quality peer-tutor training throughout the reviewed semesters. Future efforts should promote the development of national and international standards for peer-tutor training and provide certification opportunities for peer tutors.

Peer teachers as ultrasound instructors? - a systematic literature review of peer teaching concepts in undergraduate ultrasound education

BACKGROUND

As ultrasound is one of the most utilized imaging procedures in clinical practice in Germany, its integration into undergraduate medical education is imperative. Thereby, the limited availability of qualified instructors is a major challenge. Peer tutors, who are trained to instruct their peers collaboratively, could resolve staff constraints. This systematic review explores the literature on peer teaching in undergraduate ultrasound education, aiming to provide an overview of methodologies, outcomes, and peer teacher training concepts.

METHODS

Following the PRISMA guidelines, a systematic literature review was conducted on the subject of peer teaching in undergraduate ultrasound education. Using PubMed and Google Scholar as databases, studies in English or German involving training concepts for peer teachers in undergraduate ultrasound education, published up to November 21, 2023, were included. Data extraction of original studies followed the PICOS schema with special respect to didactic concepts of peer tutor training programs and the effectiveness of peer teachers compared to faculty instructors. A modified version of the Newcastle-Ottawa Scale (NOS) was used to assess the quality of included studies.

RESULTS

Finally, the search resulted in 20 relevant original studies, including 16 studies exploring peer teacher training concepts. Predominantly, peer teachers studied in their 4th year of medical school and on average one year further compared to their students. Peer teacher training was integrated into curricula by course-based concepts (93.8%) and internships (50.0%). Didactic modalities varied, encompassing laboratory rotations including the scanning of patients, the scanning of fellow students, lectures, and didactic training. The median training duration was about ten days. Of six comparative studies, five found peer-assisted learning to be comparably effective and one even better than faculty-led courses.

CONCLUSION

Despite the growing amount of literature underlining the effectiveness and wide application of peer teaching in ultrasound education, training concepts stay heterogenous without a standardized system for training and qualifying peer teachers. Developing comprehensive guidelines for peer tutor education could increase acceptance and recognition of peer-assisted learning and ensure minimum training standards.

Teaching through their eyes: effects on optometry teachers' adaptivity and students' learning when teachers see students' gaze

Adaptive teacher support fosters effective learning in one-to-one teaching sessions, which are a common way of learning complex visual tasks in the health sciences. Adaptive support is tailored to student needs, and this is difficult in complex visual tasks as visual problem-solving processes are covert and thus cannot be directly observed by the teacher. Eye-tracking apparatus can measure covert processes and make them visible in gaze displays: visualizations of where a student looks while executing a task. We investigate whether live dynamic gaze displays help teachers in being more adaptive to students' needs when teaching optical coherence tomography interpretation in one-to-one teaching sessions and whether this fosters learning. Forty-nine students and 10 teachers participated in a one-to-one teaching session in clinical optometry. In the control condition, teachers saw the learning task of the student and could discuss it with them, whereas in the gaze-display condition, teachers could additionally see where the student looked. After the 15-minute teaching session, a test was administered to examine achievement. Furthermore, students filled in the 'questionnaire on teacher support adaptivity', and teachers rated how adaptive their support was. Bayesian analyses provide some initial evidence that students did not experience support to be more adaptive in the gaze-display condition versus the control condition, nor were their post-test scores higher. Teachers rated their provided support as being more adaptive in the gaze-display versus the control condition. Further research could investigate if live dynamic gaze displays impact adaptive teaching when used over longer periods or with more teacher training.

Student Ultrasound Education, Current Views and Controversies; Who Should be Teaching?

Acquiring diagnostic ultrasound competencies and skills is crucial in modern health care, and achieving the practical experience is vital in developing the necessary anatomy interpretation and scan acquisition skills. However, traditional teaching methods may not be sufficient to provide hands-on practice, which is essential for this skill acquisition. This paper explores various modalities and instructors involved in ultrasound education to identify the most effective approaches. The field of ultrasound instruction is enriched by the diverse roles of physicians, anatomists, peer tutors, and sonographers. All these healthcare professionals can inspire and empower the next generation of ultrasound practitioners with continuous training and support. Physicians bring their clinical expertise to the table, while anatomists enhance the understanding of anatomical knowledge through ultrasound integration. Peer tutors, often medical students, provide a layer of social congruence and motivation to the learning process. Sonographers provide intensive practical experience and structured learning plans to students. By combining different instructors and teaching methods, success can be achieved in ultrasound education. An ultrasound curriculum organized by experts in the field can lead to more efficient use of resources and better learning outcomes. Empowering students through peer-assisted learning can also ease the burden on faculty. Every instructor must receive comprehensive didactic training to ensure high-quality education in diagnostic ultrasound.

What do medical students think are characteristics of a good ultrasound tutor? A qualitative study

PURPOSE

This study was designed to elicit medical students' opinions on the characteristics of a good ultrasound tutor. The results should help educators to create an optimal teaching environment and inform tutor training.

MATERIALS AND METHODS

The qualitative study recruited 15 participants from a larger mixed-methods study of 64 medical students who underwent a basic course on abdominal ultrasound taught by faculty and near-peer tutors. During semi-structured interviews, they were asked which characteristics make a good ultrasound tutor. We used inductive thematic analysis to identify the most important categories.

RESULTS

Medical students identified teaching themes and subthemes relating to teaching skills (e.g., course structure, repetition, vocabulary, feedback, guidance of participants), tutors' attitudes (e.g., atmosphere creation, empathy) and knowledge as the crucial components of being a good ultrasound tutor.

CONCLUSIONS

While some of the themes that students identified are generic to medical education, others are specific to ultrasound teaching. Tutors can use our results to assess their own teaching. They should aim to address learning needs, optimise understanding, give adequate feedback, and create a non-threatening atmosphere with empathic interactions. Accounting for the ultrasound-specific setting they should possess the necessary knowledge, provide verbal guidance to their students, and distribute examination time wisely.

The urgent need to extend the appropriate use of ultrasound in Africa and worldwide. Overview, experiences and perspectives

It is known that in African countries the health condition is problematic, both from a diagnostic and therapeutic point of view. Patients have to travel long distances to access medical care. Many cannot afford the cost of transportation to a medical facility. Ultrasound its into the scenario of healthcare imaging with limited resources, as an effective, economical, repeatable diagnostic tool, requiring low maintenance. Ultrasound tools in fact are relatively cheap and machines are easy to move, making them adapt to be taken to a rural setting where they are most needed. However ultrasound exams are not easy to perform and they need an adequate training. The spread of POCUS (point-of-care "focused" ultrasound) worldwide could be useful in Africa to identify high-risk patients. These cases selected in rural setting by POCUS can be referred to hospitals for further treatment. To deal with these situations it is necessary to form doctors and/or paramedical staff capable of guaranteeing a qualitatively adequate service. Therefore the need for basic training is greater in developing countries. Sharing successful educational strategies should advance the integration of ultrasound into the university medical school curricula. This will ensure that recently qualified doctors can practice their basic skills accurately and independently.

Integrating traditional apprenticeship and modern educational approaches in traditional Chinese medicine education

BACKGROUND

The traditional apprenticeship system and modern educational models both contribute to traditional Chinese medicine (TCM) education in unique ways. This study aims to evaluate the advantages and disadvantages of these approaches and investigates their potential integration for optimal TCM teaching.

METHODS

The study employs a comprehensive literature search strategy with specific keywords through Boolean Operators, focusing on articles discussing TCM education, sourced from the databases PubMed, Scopus, and CNKI. For comparative analysis, the study analyzes the advantages and disadvantages of three distinct approaches-traditional, modern, and hybrid-in TCM education. Finally, we use a spider plot methodology to visually evaluate across 11 critical educational aspects for these approaches.

RESULTS

A comprehensive review of 70 articles on TCM education highlights the value of both conventional and modern approaches. Conventional methods often emphasize teacher-centered clinical training that aligns well with the apprenticeship model, serving to bridge formal academic learning with hands-on experience. Modern methods incorporate elements like technology and formal accreditation but caution that the absence of traditional apprenticeship could dilute core TCM principles. One recurring theme across multiple studies is the enduring importance of apprenticeship-a pedagogical cornerstone rooted in TCM's historical and cultural context-as well as its tension with modern methodologies that incorporate online resources and scientific frameworks. An integrated approach attempts to harmonize these strengths but reveals a gap in interactivity, suggesting that incorporating apprenticeship could offer a practical, hands-on method to improve student engagement.

CONCLUSIONS

Conventional methods in TCM education emphasize teacher-centered clinical training akin to apprenticeship, modern methods incorporate technological advances and formal accreditation; however, the absence of traditional apprenticeship could compromise core TCM principles, and an integrated model, though striving to harmonize these elements, still falls short in the area of student interactivity.

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.

Near-peer compared to faculty teaching of abdominal ultrasound for medical students - A randomized-controlled trial

PURPOSE

Medical schools increasingly rely on near-peer tutors for ultrasound teaching. We set out to compare the efficacy of a blended near-peer ultrasound teaching program to that of a faculty course in a randomized controlled trial.

METHODS

152 medical students received 21 hours of ultrasound teaching either by near-peer teachers or medical doctors. The near-peer course consisted of blended learning that included spaced repetition. The faculty-led course was the European common course for abdominal sonography. The primary outcome measurement was the students' ultrasound knowledge at month 6, assessed by structured examination (score 0 to 50). Secondary outcomes included scores at month 0 and changes in scores after the course.

RESULTS

Students in the near-peer group scored 37 points, and students in the faculty group scored 31 points six months after course completion. The difference of 5.99 points (95% CI 4.48;7.49) in favor of the near-peer group was significant (p<0.001). Scores immediately after the course were 3.8 points higher in the near-peer group (2.35; 5.25, p<0.001). Ultrasound skills decreased significantly in the six months after course completion in the faculty group (-2.41 points, [-3.39; -1.42], p<0.001]) but barely decreased in the near-peer group (-0.22 points, [-1.19; 0.75, p=0.66]).

CONCLUSION

The near-peer course that combined blended learning and spaced repetition outperformed standard faculty teaching in basic ultrasound education. This study encourages medical schools to use peer teaching combined with e-learning and spaced repetition as an effective means to meet the increasing demand for ultrasound training.

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.

Building Consensus on the Point-of-Care Ultrasound Skills Required for Effective Healthcare Service Delivery at District Hospitals in South Africa: A Delphi Study

BACKGROUND

Despite the widespread availability of ultrasound machines in South African district hospitals, there are no guidelines on the competency in point-of-care ultrasound (POCUS) use required by generalist doctors in this setting. This study aimed to define the required POCUS competencies by means of consensus via the Delphi method.

METHODS

An online Delphi process was initiated in June 2022, using the existing American Academy of Family Physicians' ultrasound curriculum (84 skillsets) as the starting questionnaire. Panelists were selected across the country, including two from district hospitals in each province and two from each academic family medicine department in South Africa (N = 36). In each iterative round, the participants were asked to identify which POCUS skillsets were essential, optional (region-specific), or non-essential for South African district hospitals. This process continued until consensus (>70% agreement) was achieved on all of the skillsets.

RESULTS

Consensus was achieved on 81 of the 84 skillsets after 5 iterative rounds (96.4%), with 3 skillsets that could not achieve consensus (defined as <5% change over more than 2 consecutive rounds). The final consensus identified 38 essential, 28 optional, and 15 non-essential POCUS skillsets for the South African district hospital context.

CONCLUSIONS

The list of essential POCUS skillsets provided by this study highlights the predominance of obstetric- and trauma-based skillsets required for generalist healthcare workers in South African district hospitals. The findings will require priority setting and revalidation prior to their implementation across the country.
