Primary among the goals of the ANSI-approved MedBiquitous VP (MVP) standard is the ability to exchange and repurpose virtual patient (VP) cases between disparate authoring systems. Hundreds of VP cases are publicly available in the MVP format, primarily from the eViP consortium, derived from the CAMPUS, CASUS, OpenLabyrinth, vpSim and WebSP authoring systems. The Lab for Educational Technology (the Lab) at the University of Pittsburgh created vpSim based on the MVP standard and with the ability to import and export cases regardless of the system they originated from. The Lab conducted experiments to determine how well the MVP standard works for importing and repurposing available MVP packages into vpSim. Results were analyzed based on ability to import and display 1) text, 2) multimedia, 3) questions, and 4) if authoring/editing was possible after import. Compared to their original format, text typically imported intact, multimedia was usually successful, but questions only rarely. Greatest compatibility for authoring/editing was between vpSim and OpenLabyrinth cases. Incompatibility was a result of variation in the structure of the cases, the accuracy of the XML packages and the way systems interpreted the standard. Data collected should inform VP users, systems designers, and refinement of the MVP standard.
