Abstract
Background Knee joint injections and aspirations are essential procedures for medical students, residents, and primary care physicians to master. Simulation-based training has been shown to improve learner confidence and performance scores in knee joint injections. Current knee joint simulators are expensive, ranging from hundreds to thousands of dollars. Using three-dimensional (3D) printing and gel layering technology, we designed and manufactured an inexpensive simulator. The aim of this implementation study was to gather the opinions of local simulation specialists and administrators regarding the simulator's curricular implementation. Methods Using the Consolidated Framework for Implementation Research (CFIR), we developed a 31-item implementation survey. It was administered to local simulation specialists and administrators. The purpose of the survey was to identify the aspects of the simulator that they deemed important to the implementation process, as well as obtain their qualitative feedback about the design. Results In total, three participants completed the survey. There were 16 survey items that were rated as very important, including local manufacturing, appropriate planning, internal development, evidence-based development, and reasonable costs. Another nine items were deemed important, including the adaptability of the product and ability to test the product. The simulation specialists also expressed some concerns they had with the design of the simulator and made suggestions about how we could address these concerns. Conclusions Local development and manufacturing, coupled with appropriate pre-implementation planning and efficacy evidence, were selected as factors that would potentially contribute to the success of the implementation of the simulator in the local curriculum.
