Physicians' offices are not the usual place where emergencies occur; thus how staff remains prepared and current regarding medical emergencies presents an ongoing challenge for private practitioners. The very nature of low-volume, high-risk, and problem-prone medical emergencies is that they occur with such infrequency it is difficult for staff to maintain competency and relevant knowledge and skills. Virtual reality (VR) has been proven an invaluable tool in the aviation, engineering, and military fields. Virtual worlds have been shown to be highly immersive and engaging. The ability to create sufficient detail to artifacts with which the physician and clinician will interact provides similar affordances as would their counterparts in reality. This close approximation through visual representations, spatial relationship that objects share with each other and with the avatar, and overall context created by the VR provide strong support for the transfer of learning from the VR to clinical setting. This study examined the development process for VR medical simulations that presented office-based emergencies, necessitated team interactions, and provided opportunities for participants to use countermeasures using a design-based research methodology. The VR environment provided a substantial overlap between the learning context, the participant's historical knowledge, and their performance at the point-of-care. Using a design-based research approach was very effective means of working with experimental design principles derived from literature and prototype projects. This research examined the optimal design needed to facilitate situation awareness, effective communications, and clinical decision-making in emergent situations and provides practical insights into the design of 3D virtual reality based medical simulations to create an optimal experience for learners.
