Task Trainer Augmented Joint Reduction Training
Abstract
Learning Objectives: To investigate whether augmenting joint reduction education with 3D printed task trainers will offer a learning benefit when paired with traditional teaching methods using lectures and videos. The application is focused on EM residents with potential expansion to surgical subspecialties.
Introduction: Prior studies and EM training programs have called for the need for innovation in the realm of orthopedic education. When compared to other core skills developed during EM residency, joint reductions are relatively infrequent. The development of 3D printing technology offers an opportunity for the development of task trainers to supplement resident experience. There are no current 3D printed task trainers available for joint reductions. We developed a series of 3D printed joint models with orthopedic curriculum to supplement exposure to dislocation reductions to improve emergency medicine residents’ preparedness, confidence, and competency in joint dislocation reductions. Models were designed to create tension and tactile feedback upon reduction. The supplemental curriculum summarized patient evaluation, anatomy, and techniques.
Curricular Design: We utilized the trainers in simulation sessions with reductions taught using Peyton’s 4 step approach, and competency assessed through Miller’s pyramid educational theory. A likert type survey was administered to assess resident learning, preference in teaching style, and confidence in reduction techniques. Baseline experience data was collected to assess prior clinical experience. Learning retention will be assessed during the follow up skill session. Given the variety of joints designed, we divided sessions to include 1-2 joints at a time. This allowed for more focus on specific joints as well as space repetition across multiple sessions throughout the academic year.
Impact/Effectiveness: The current set of data strongly supports the utilization and integration of 3D models into the education of emergency medicine residents in joint dislocation reductions. The vast majority of resident learners found benefit in the inclusion of 3D printed joint models. Although most learners preferred the 3D printed models compared to traditional teaching methods, we advocate for an integrated teaching model rather than choosing only one teaching technique.
