Practical Application of Educational Theory for Learning Technical Skills in Emergency Medicine

The development, implementation, and evaluation of a medical student peer teaching training curriculum during a high-fidelity prehospital trauma simulation

Objectives

While peer teaching has been found to be an effective technique during simulation, no peer teaching training curriculum (PTTC) has been developed for simulation-based learning. The objective of this study, therefore, was to develop, implement, and evaluate a PTTC during a high-fidelity trauma simulation.

Methods

When developing the PTTC, we combined several validated learning models for teaching and learning procedural skills. We then implemented it over 6 days in two phases: instructional (learning how to teach) and experiential (practicing teaching). Our research team conducted a qualitative evaluation to evaluate the effectiveness of the PTTC. We analyzed written self-reflections from 20 second-year medical students who completed the PTTC. Using an iterative inductive approach to data analysis, our research team first individually coded the reflection papers. We then met to define and categorize the codes into themes. Finally, we compared these themes to the PTTC's objectives to evaluate the curriculum's effectiveness.

Results

The following themes emerged from the data: 1) learning through teaching; 2) self-actualization as an educator; and 3) role of physician as leader, advocate, and educator. The students described how the peer teaching experience improved their own procedural knowledge and skills. They also reported an increase in their leadership and communication skills as they effectively provided guidance and feedback to their peers, which led to their self-actualization as an educator. This self-actualization inspired the peer teachers' professional identity formation as leaders and educators in medicine.

Conclusions

Based on these themes, we found our PTTC to be an effective curricular design. Our results reinforce previously described benefits to both peer teachers and learners in regard to medical knowledge and skills acquisition and furthers the academic emergency medicine community's understanding of how students' involvement as peer teachers in simulation-based education impacts their professional development.

Simulation and Modeling Applications in Global Health Security

Global health security (GHS) is dependent upon having an adequate and prepared health security workforce. There are currently numerous challenges in establishing and maintaining a health security workforce. The frequency and magnitude of disasters have increased significantly over the past 30 years. Current and future GHS threats, both manmade and natural, require a prepared and flexible healthcare provider workforce ready to respond to current or emerging GHS threats. Developing and maintaining GHS -specific skills in the healthcare workforce is a tremendous logistical challenge. Innovative education technologies, including simulation and digital learning, can be leveraged to achieve preparedness for GHS threats.

This chapter focuses on the application of modeling and simulation to support Global Health Security planning, preparedness and operations.

Yogaman: An Inexpensive, Anatomically-detailed Chest Tube Placement Trainer

Introduction

Opportunities for chest tube placement in emergency medicine training programs have decreased, making competence development and maintenance with live patients problematic. Available trainers are expensive and may require costly maintenance.

Methods

We constructed an anatomically-detailed model using a Halloween skeleton thorax, dress form torso, and yoga mat. Participants in a trial session completed a survey regarding either their comfort with chest tube placement before and after the session or the realism of Yogaman vs. cadaver lab, depending on whether they had placed <10 or 10 or more chest tubes in live patients.

Results

Inexperienced providers reported an improvement in comfort after working with Yogaman, (comfort before 47 millimeters [mm] [interquartile ratio {IQR}, 20–53 mm]; comfort after 75 mm [IQR, 39–80 mm], p=0.01). Experienced providers rated realism of Yogaman and cadaver lab similarly (Yogaman 79 mm [IQR, 74–83 mm]; cadaver lab 78 mm [IQR, 76–89 mm], p=0.67). All evaluators either agreed or strongly agreed that Yogaman was useful for teaching chest tube placement in a residency program.

Conclusion

Our chest tube trainer allowed for landmark identification, tissue dissection, pleura puncture, lung palpation, and tube securing. It improved comfort of inexperienced providers and was rated similarly to cadaver lab in realism by experienced providers. It is easily reusable and, at $198, costs a fraction of the price of available commercial trainers.
