High-fidelity simulation training programme for final-year medical students: implications from the perceived learning outcomes

A Paper-Based Simulation Model for Teaching Inguinal Hernia Anatomy

BACKGROUND

Inguinal hernias remain a challenging area of learning for medical students due to its relatively complex anatomy. Modern curriculum delivery methods are conventionally limited to didactic lectures and demonstration of anatomy intraoperatively. These strategies have limitations; lectures are inherently descriptive and based on 2-dimensional models, while intraoperative teaching is often unstructured and opportunistic.

METHODS

A paper-based model was developed comprising three overlapping paper panels simulating the anatomical layers of the inguinal canal which can be modified readily to further simulate various hernia pathologies and their surgical repair. These models were incorporated into a timetabled structured learning session for 3rd- and 4th-year medical students. Learners responded to fully anonymised surveys before and after the learning session.

FINDINGS

A total of 45 students participated in these sessions over a period of 6 months. Pre-learning session mean ratings for the learners' confidence in their understanding of the layers of the inguinal canal, identifying indirect and direct inguinal hernias and in naming the contents of the inguinal canal were 2.5, 3.3 and 2.9, while post-learning session mean ratings were 8.0, 9.4 and 8.2, respectively. Paired samples Student's t-tests for all three questions were statistically significant (p < 0.001). The mean rating for usefulness of the session was 9.6/10. Free comments from students emphasised the models' usefulness as a visual learning aid.

DISCUSSION AND CONCLUSION

Our novel, low-cost paper model was associated with an improvement in learners' perceived knowledge and understanding of inguinal canal anatomy and pathology.

The role of high-fidelity simulation in the acquisition of endovascular surgical skills: a systematic review

INTRODUCTION

The widespread introduction of minimally invasive endovascular techniques in cardiovascular surgery has necessitated a transition in the psychomotor skillset of trainees and surgeons. Simulation has previously been used in surgical training; however, there is limited high quality evidence regarding the role of simulation-based training on the acquisition of endovascular skills. This systematic review aimed to systematically appraise the currently available evidence regarding endovascular high-fidelity simulation interventions, to describe the overarching strategies used, the learning outcomes addressed, the choice of assessment methodology, and the impact of education on learner performance.

METHODS

A comprehensive literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using relevant keywords to identify studies evaluating simulation in the acquisition of endovascular surgical skills. References of review articles were screened for additional studies.

RESULTS

A total of 1081 studies were identified (474 after removal of duplicates). There was marked heterogeneity in methodologies and reporting of outcomes. Quantitative analysis was deemed inappropriate due to the risk of serious confounding and bias. Instead, a descriptive synthesis was performed, summarising key findings and quality components. Eighteen studies were included in the synthesis (15 observational, 2 case-control and 1 randomised control studies). Most studies measured procedure time, contrast usage, and fluoroscopy time. Other metrics were recorded to a lesser extent. Significant reductions were noted in both procedure and fluoroscopy times with the introduction of simulation-based endovascular training.

CONCLUSION

The evidence regarding the use of high-fidelity simulation in endovascular training is very heterogeneous. The current literature suggests simulation-based training leads to improvements in performance, mostly in terms of procedure and fluoroscopy time. High-quality randomised control trials are needed to establish the clinical benefits of simulation training, sustainability of improvements, transferability of skills and its cost-effectiveness.

Medical Student Experiential Learning in Telesimulation

OBJECTIVES

Telesimulation utilizes telecommunication technology to engage learners in simulation while in different physical locations. Despite this potential advantage, understanding of the student experience and assessment of student learning in telesimulation activities is limited. This study evaluates medical student emotional experience and self-identified learning in telesimulation through the Kolb experiential learning framework and qualitative analysis.

METHODS

Fourth-year medical students enrolled in the Spencer Fox Eccles School of Medicine at the University of Utah participated in 3 telesimulation activities as part of a required internal medicine course. Students were surveyed regarding their satisfaction with the activity (N = 114) and responded to questions about their emotional experience and self-identified areas of learning. Free-text responses were analyzed using qualitative content analysis to identify themes until thematic saturation (N = 66).

RESULTS

Students were highly satisfied with telesimulation, with greater than 90% of students expressing a positive view of simulation realism, debrief quality, and group size. Themes of anxiety and uncertainty, confidence versus incompetence, team dynamics, fun, and difficult patient interaction were identified regarding the emotional experience. Themes of communication and teamwork, managing emotions, information gathering, differential diagnosis, resource reference, executing treatment, and medical knowledge were identified regarding student-identified learning.

CONCLUSION

In this analysis of medical student experiences with telesimulation, we found students have rich emotional, cognitive, and behavioral experiences and self-identify learning across a variety of domains. Our findings support further study of telesimulation for medical student learning and demonstrate how assessment of outcomes via Kolb framework, using the learner's reflective observation and self-identified learning, may help better define learning outcomes from simulation.

Multimodal In-training Examination in an Emergency Medicine Residency Training Program: A Longitudinal Observational Study

Background

In-training examination (ITE) has been widely adopted as an assessment tool to measure residents' competency. We incorporated different formats of assessments into the emergency medicine (EM) residency training program to form a multimodal, multistation ITE. This study was conducted to examine the cost and effectiveness of its different testing formats.

Methods

We conducted a longitudinal study in a tertiary teaching hospital in Taiwan. Nine EM residents were enrolled and followed for 4 years, and the biannual ITE scores were recorded and analyzed. Each ITE consisted of 8–10 stations and was categorized into four formats: multiple-choice question (MCQ), question and answer (QA), oral examination (OE), and high-fidelity simulation (HFS) formats. The learner satisfaction, validity, reliability, and costs were analyzed.

Results

486 station scores were recorded during the 4 years. The numbers of MCQ, OE, QA, and HFS stations were 45 (9.26%), 90 (18.5%), 198 (40.7%), and 135 (27.8%), respectively. The overall Cronbach's alpha reached 0.968, indicating good overall internal consistency. The correlation with EM board examination was highest for HFS (ρ = 0.657). The average costs of an MCQ station, an OE station, and an HFS station were ~3, 14, and 21 times that of a QA station.

Conclusions

Multi-dimensional assessment contributes to good reliability. HFS correlates best with the final training exam score but is also the most expensive format among ITEs. Increased testing domains with various formats improve ITE's overall reliability. Program directors must understand each test format's strengths and limitations to bring forth the best combination of exams under the local context.
