For the most part, the case authoring tool is simple. The only aspect of it that may require some practice is manipulating case logic. Case logic allows the author to control all aspects of the case, from how the patient reacts to various actions to what it takes to “win” the case. VRpatients offers a free “VRpatients University” to help users get the most out of their case building. After a bit of practice, users rapidly acclimate to the building of case logic strings.
This varies greatly depending on the complexity of the case. For example, a case featuring a patient with a stomach ache may take only minutes to construct from scratch. A case featuring an unconscious patient with arrhythmias may take an hour or two, or perhaps even more than that. The beauty is you are free to develop what you want, rather than just be given a case to run that never changes.
VRpatient statistics show that the vast majority of users at least make edits to the case templates that are provided with the program. This keeps cases fresh, and helps prevent students or medics from learning the case through repetition after a couple of times through. Interviews with customers also show that as instructors become comfortable with editing cases, they inevitably start building their own cases from scratch.
