The central venous catheter kit, containing over 10 items, can overwhelm first-time trainees. To address this, we’re creating a learning experience that merges an online module with 3D-printed models for medical trainees to start identifying these items in the kit before they learn how to perform the procedure.
The study comprised three primary phases. Phase I involved observing experienced medical professionals as they prepared a central venous catheter kit. This observation aimed to provide insights for designing a serious game tailored for trainees, which constituted Phase II. The serious game was developed by transforming medical instruments into 3D assets, creating an online interactive platform, and producing physical game pieces through 3D printing. In Phase III, both trainees and experts were engaged in a usability test to assess the effectiveness and user experience of the developed serious game.
Observing the experts underscored the significance of grouping instruments by function rather than assigning them fixed locations, emphasizing the need to adapt their organization to various environments encountered. For 3D-printed game pieces, all users preferred the 3D-printed miniature replicas over the semi-3D cards despite greater durability of the latter. All users firmly support introducing trainees to this serious game prior to working with the actual kits.
By leveraging 3D modeling, printing, animation, programming, web design, and AI, we developed an integrated educational tool that will aid medical practitioners in optimizing the organization of sterile instruments for central venous catheter placement. Our experience lays the groundwork for future advancements in serious games for diverse medical procedures.
