Video-based, student tutor- versus faculty staff-led ultrasound course for medical students - a prospective randomized study

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.

The effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education: a pilot randomized controlled trial

BACKGROUND

Effective teaching methods are needed to improve students' abilities in hand-eye coordination and understanding of cardiac anatomy in echocardiography education. Simulation devices have emerged as innovative teaching tools and exhibited distinctive advantages due to their ability to provide vivid and visual learning experiences. This study aimed to investigate the effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education.

METHODS

The study included 18 first-year clinical medical students with no prior echocardiography training. After randomization, they underwent a pre-test to assess basic knowledge. Following this, the students were divided into two groups: traditional teaching (traditional group) and simulation of sectional human anatomy using ultrasound (digital group). Each group received 60 min of instruction. Post-tests were assigned to students at two different time points: immediately after the lecture, and one week later (referred to as post-tests 1, and 2). In addition, anonymous questionnaires were distributed to students after class to investigate their satisfaction with teaching.

RESULTS

Both groups showed significant improvement in their scores on post-test 1 compared to pre-test (traditional group: from 33.1 ± 8.8 to 48.1 ± 13.1, P = 0.034 vs. digital group: from 35.0 ± 6.7 to 58.0 ± 13.2, P = 0.008). However, there were no significant differences between the two groups in several post-test comparisons. Student satisfaction ratings revealed that the digital group experienced significantly greater satisfaction in areas such as subject interest, teaching style, course alignment, and interaction compared to the traditional group. Additionally, 80% of the digital group strongly endorsed the use of simulation of sectional human anatomy using ultrasound for echocardiography teaching, highlighting its effectiveness.

CONCLUSIONS

Simulation of sectional human anatomy using ultrasound may improve students' understanding of echocardiography and satisfaction with the course. Our study provides evidence supporting the use of simulation teaching devices in medical education. Further research is needed to explore the long-term impact of this teaching method on students' learning outcomes and its integration into the medical curriculum.

Comparison of peer-assisted learning with expert-led learning in medical school ultrasound education: a systematic review and meta-analysis

INTRODUCTION

Teaching point-of-care ultrasonography (PoCUS) to medical students is resource intensive. Peer-assisted learning, where the teacher can be a medical student, may be a feasible alternative to expert-led learning. The objective of this systematic review and meta-analysis was to compare the PoCUS performance assessments of medical students receiving peer-assisted vs expert-led learning.

METHODS

This study was submitted to PROSPERO (CRD42023383915) and reported with PRISMA guidelines. MEDLINE, Embase, ERIC, Education Source, Scopus, and Web of Science were searched from inception to November 2022. Inclusion criteria were studies comparing peer-assisted vs expert-led PoCUS teaching for undergraduate medical students. The primary outcome was performance assessment of PoCUS skills. Two reviewers independently screened citations and extracted data. The Cochrane risk-of-bias tool for randomized trials was used to assess study quality. Studies were included in the meta-analysis if mean performance assessment scores with standard deviations and sample sizes were available. A random-effects meta-analysis was conducted to estimate the accuracy score of practical knowledge test for each group. A meta-regression evaluated difference in mean scores.

RESULTS

The search yielded 2890 citations; 1417 unique citations remained after removing duplicates. Nine randomized-controlled studies conducted in Germany, USA, and Israel, with 593 participants, were included in the meta-analysis. The included studies assessed teaching of abdominal, cardiac, thoracic, musculoskeletal, and ocular PoCUS skills. Most studies had some risk-of-bias concerns. The estimate accuracy score after weighting is 0.56 (95% CI [0.47, 0.65]) for peer-assisted learning and 0.59 (95% CI [0.49, 0.69]) for expert-led learning. The regression coefficient estimate is 0.0281 (95% CI [- 0.1121, 0.1683]); P value is 0.69.

CONCLUSION

This meta-analysis found that peer-assisted learning was a reasonable alternative to expert-led learning for teaching PoCUS skills to medical students.

Perception and attitude towards online clinical modules: a cross-sectional study among medical students from two countries

COVID-19 has deeply affected the world in various aspects including the education system worldwide. In this study, we intended to explore the merits and demerits of online clinical learning and its effect on medical education from a student's perspective. The study also assessed the perception and attitude of final-year medical students towards online clinical modules. This observational study was carried out in the Department of Community Medicine, Kasturba Medical College, Manipal (KMC) in collaboration with King's College London, UK (KCL). In our study, a total of 42 students were enrolled, with 37 students from KMC and 5 students from KCL. 81% of students reported that they were not willing to continue the online mode of learning. The abrupt switch to e-learning without prior preparedness has exposed some pitfalls that must be attended to. Contrary to other fields, the medical field places high importance on offline clinical teaching which has recently been impacted by online teaching. The survey responses were analyzed for improvisation of online clinical modules as well as to come up with better ideas and outcomes since this mode of learning may have to continue till the spread of the disease is under control.

The effects of mentorship and educational videos on nursing students' physical examination skills: a clinical audit

BACKGROUND

Poor competence in clinical examination skills among nurses has been reported in practice, and there is a strong consensus that physical examination (PE) education must be improved. However, deficiencies cannot be resolved by theoretical training alone, and new training approaches are required to enable nursing students to perform PE accurately. This study aimed to determine and compare the effect of two new educational methods (mentorship and educational video methods) on the physical examination skills of Iranian nursing students.

METHODS

This study was a clinical audit with three group pretest posttest design. Eligible nursing students were recruited through the census method and assigned to three groups (mentorship, educational videos, and control group) using permuted block randomization. Students were taught PE skills in three vital systems through three approaches (mentors, educational videos, and routine educational methods). Data were collected using a two-part instrument consisting of a demographic information questionnaire and a 32-item checklist for assessing the students' skills in examining the respiratory system (10 items), cardiovascular system (13 items), and 12 cranial nerves (9 items). Data were analyzed using SPSS software version 16 and descriptive and analytical statistical tests.

RESULTS

At baseline, students in all groups scored less than half of the possible scores in all three systems, and the mean scores of the three groups were not statistically different (P > 0.05). After the intervention, the mean scores of students in the mentorship group increased significantly in all three systems (P < 0.001), whereas the mean scores of students in the educational video group and the control group did not change significantly (P > 0.05). Furthermore, after the intervention, the mean scores of the educational video group and the control group did not significantly differ in any of the three systems (P > 0.05). The ANCOVA showed that with posttest score as the covariate, PE skills in all three systems improved one week after the intervention in the mentor group compared to the control group and the educational video group. However, PE skills in all three systems did not improve one week after the intervention in the educational video group compared to the control group.

CONCLUSIONS

The mentorship method is more effective than the educational video and routine methods for teaching PE skills to nursing students. Nursing schools can use the mentor method in training nursing students, and it is recommended to revise the PE lesson unit in the nursing curriculum and exchange it from a purely theoretical-based unit to a mixture of theoretical and clinical-based training. Educational videos alone cannot improve nursing students' PE skills; thus, if educational videos are used to teach clinical skills, it is necessary to hold hands-on sessions to provide feedback to students and correct their mistakes.

Assessing the Use of Telepresence-Guided Video-Based Head and Neck Ultrasound Training: A Step towards Minimizing Dependence on Human Resources?

The acquisition of ultrasound skills is an essential part of any medical student's education. University access restrictions in the context of the COVID-19 pandemic have highlighted the need for digitization in teaching. However, teaching manual skills in online courses has proven to be challenging, not least in terms of human resources. Therefore, the aim of this study was to set up a hybrid head and neck ultrasound course consisting of a preface of video-based self-study followed by supportive instruction by a tutor in telepresence and to evaluate the quality, effectiveness, and feasibility of this teaching method. Thirty-five students were shown video tutorials on systematic ultrasound of the neck course. Learning outcomes were analyzed using self-assessment questionnaires and external assessment by an experienced ultrasonographer. All participants demonstrated statistically significant learning improvement (p < 0.001) when comparing self-assessment scores before and after training. The mean self-assessment scores increased from 13.8 to 26.6 for the telepresence-guided group, from 16.6 to 27.3 for the web-based group, and from 14.0 to 26.2 for the in-person group. The external observer assessment also showed improvement, with mean scores of 46.7, 48.1, and 46.5, respectively. Overall results did not significantly differ when comparing different instruction modalities. A telepresence-guided video-based ultrasound course is well suited to teaching ultrasound skills similar to in-person courses and allows a more resource-efficient targeting of student needs.

The Role of Collaborative Observational Practice and Feedback-Discourse to Promote Remote Acquisition of Technical Surgical Skills

INTRODUCTION

Acquisition of technical skills remotely in a decentralized model requires an efficacious way of providing feedback. The primary objective was to test the efficacy of various forms of feedback on the acquisition of surgical skills by medical students.

METHODS

Forty volunteers were randomized to four experimental groups, differing from the nature of feedback (free text versus structured) and who provided the feedback (expert versus peer learners). They had to perform sutures and upload attempts on a learning management system to receive interactive feedback. The pretest and retention test performances were assessed.

RESULTS

All groups significantly improved from pretests to retention tests; however, participants using checklist showed statistically lower improvements than the other groups, which did not differ from each other.

CONCLUSIONS

Remote learners can acquire surgical skills, and most importantly, peers who provide feedback, are as effective as experts if they use open-ended comments and not checklists.

"LEARN", a novel teaching method for Chinese clinical clerkship: A cross-sectional study

Background

Despite the clerkship being crucial in the training of a future doctor, no widely accepted education model has been proposed. This study devised a new model for clinical clerkship rotations, titled "LEARN" for Lecture, English-video, Advisor, Real-case and Notion, and evaluated whether the LEARN model is appropriate for medical education in China.

Methods

A cross-sectional study was performed among 101 fourth-year students from the Xiangya School of Medicine during an Orthopaedic Surgery clerkship rotation in the Third Xiangya Hospital. They were divided into seven groups and took clerkship based on the LEARN model. A questionnaire was collected at the conclusion to measure learning outcomes.

Results

The LEARN model was highly accepted with the acceptance of five sessions being 95.92% (94/98), 93.88% (92/98), 96.98% (97/98), 100% (98/98) and 96.94% (95/98). The outcomes of two genders were comparable, whereas a difference was observed in the test score among groups (group 3 scored 93.93 ± 5.20, higher than others). Quantitative analysis showed that positive correlations existed in participation in the Notion (Notion means students' case discussion) section with leadership (r = 0.84, 95% CI: 0.72-0.94, p < 0.001), participation in the Real-case section with leadership (r = 0.66, 95% CI: 0.50-0.80, p < 0.001), participation in the Real-case section with mastery of inquiring skills (r = 0.57, 95% CI: 0.40-0.71, p < 0.001) and participation in the Notion section with mastery of physical examination skills (r = 0.56, 95% CI: 0.40-0.69, p < 0.001). Further qualitative analysis demonstrated that high-level participation in the English-video section indicated better outcomes in mastery of inquiring (p < 0.01), physical examination (p < 0.001), film reading (p < 0.01) and clinical reasoning (p < 0.01) skills.

Conclusion

Our results support the LEARN model is a promising method for medical clerkship in China. Further research involving more participants and more meticulous design is planned to test its efficacy. For refinement, educators may try to promote students' participation in the English-video session.

Effectiveness of peer teaching in health professions education: A systematic review and meta-analysis

BACKGROUND

The reform in health professions education requires the focus to shift from fact memorization to exploring, analyzing, assimilating, and synthesizing information to promote active and collaborative learning. Peer teaching is one of the educational strategies.

AIMS

This review aimed to explore and synthesize quantitative evidence to determine the overall effect of peer teaching in enhancing students' theoretical knowledge and practical skills (e.g., procedural skills and resuscitation) in health professions education.

METHODS

PubMed, ScienceDirect, CINAHL, ERIC, ProQuest, reference lists of relevant studies, and reviews were searched till November 2021. Results were pooled using random-effects meta-analysis or narrative synthesis.

RESULTS

A total of 44 RCTs were included. This review showed a significant effect of peer teaching on procedural skills improvement and a comparable effect on theoretical knowledge and resuscitation skills acquisition compared to the conventional teaching method. Near-peer teaching seemed to be the most effective method for skill improvement. Subgroup analysis showed no significant differences between peer teaching and conventional teaching groups (e.g., expert/faculty teaching, self-study or lectures).

CONCLUSIONS

Peer teaching seems to be a promising teaching and learning strategy in health professions education, positively affecting theoretical knowledge and procedural skills. Future research should explore the effect of peer teaching in developing countries to provide a comprehensive picture of peer teaching.

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.

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.

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.

The Effectiveness of Self-Instructional Video vs. Classroom Teaching Method on Focused Assessment With Sonography in Trauma Among House Officers in University Hospital

Background: The aim of this study was to compare the effectiveness of self-instructional-video (SIV) and classroom training method (CTM) in learning Focus-Assessment with Sonography-in-Trauma (FAST) among house officers (HO).

Method: A randomized controlled study involving house officers working in the university hospital in Malaysia was conducted where participants were randomized into SIV group (intervention) and CTM group (control). Each group had to undergo a 4 h hands-on training. The intervention group has undergone self-training using the video material without any facilitation while the control group received lecture and hands-on training with facilitators. Participants' performance was assessed using a validated Objective Structured Clinical Examination checklist for landmark identification and interpretation of images generated. Learning preference and confidence level were also assessed.

Result: A total of 33 HO were enrolled in this study. Marks obtained in image acquisition by the intervention and control were 25.3 (SD = 5.3) and 25.6 (SD = 2.3) p > 0.05, respectively. While in image interpretation, the mean score for the intervention and control group was 10.3 (SD 1.7) and 9.8 (SD = 1.7) p > 0.05, respectively. Overall performance assessment, showed the intervention group obtained 35.6 (SD = 5.9) compared to control 35.3 (SD = 3.4), p > 0.05. Based on pre-specified determinant these scores difference falls within the 10% of non-inferiority margin. The absolute difference between both groups was 0.3 (CI = −3.75 to 3.21, p = 0.871), which proves non-inferiority but not superiority. In terms of learning preference and confidence to perform FAST, most of the participants preferred the control group approach.

Conclusion: The SIV method is as effective as the CTM for learning FAST among the house officers and served as an alternative to classroom teaching. However, this technique needs improvement in promoting their confidence and preference. Perhaps incorporating a feedback session after going through the SIV would improve the confidence.

E- Learning experience of the medical profession's college students during COVID-19 pandemic in Saudi Arabia

BACKGROUND

Worldwide, most of educational institutions have moved to online electronic learning methods because of the COVID-19 pandemic. On March 8, 2020, the Saudi Ministry of Education announced remote learning for public and private schools and universities as a preventive and precautionary measure to curb the spread of the coronavirus. The objective of this study was to explore the e-learning experience of the students of the colleges of health sciences with regard to the technical preparedness, academic achievements, e-learning advantages and limitations. A well-structured and validated questionnaire on a five-point Likert scale and open-ended questions about their e-learning experience was distributed to a heterogeneous purposive sample of the health sciences students in Saudi Arabian universities.

RESULTS

Of the 1288 respondents, of various demographical features a relatively higher proportion of 58.2 % agreed that they had enough information about the online learning. However, the proportion who reported receiving adequate guidance, technical support, and having satisfactory hardware and internet access to online learning were 48.1 %, 42, and 35.4 %, respectively. Of all participants, 40.8 % agreed that they had gained a good understanding of their courses learning outcomes. Only 30.0 % agreed that the quality of the online teaching was similar to traditional classes and 56.1 % agreed that the online learning is unsuitable for the medical sciences studies. E-learning advantages mentioned were the flexible accessibility of the learning materials, time, effort, and money saving, acquiring and improving technical and self-learning skills, health safety, interaction without shyness, and better academic accomplishment. On the other hand, disadvantages and difficulties included inadequate tools to facilitate online learning, poor internet connection, lack of technological skills by the educators and students. In addition, there was inadequate or lack of practical classes, lack of a unified clear policy for the conduct of online classes and exams and grade distribution, limited online exam time.

CONCLUSIONS

The sudden shift to e-learning without prior preparedness has revealed some pitfalls that need to be adjusted. The initial findings were considered satisfactory for such a new experience for both learners and students. However, there is a great chance for improving and expanding the e-learning process.
