Simulation training using virtual patients can provide many benefits for nursing and medcial students in learning patient interaction skills, especially since virtual patients can represent a wide range of patient scenarios and demographics that are not typically represented through roleplay or clinical rotations. However, creation of a single virtual patient scenario may take six months or more, so it is difficult to provide many unique scenarios during the course of a nurse's education. In this work, I propose the user-centered design, creation, and evaluation of a scenario-builder tool to enable nursing faculty to create their own scenarios, reducing development costs.
