A facet-based system for computer-assisted instruction in pain management for elderly patients.

DIANA2, a web-based interactive tutor for pain management (see www.talariainc.com), was more effective than conventional methods of learning (such as reading articles that contain the same type of information) in making the principles of pain management for the elderly more easily accessible to learners. DIANA2 was similarly effective for different types of health care providers (students, nurses, and residents), and the study participants were excited by their experience with a different mode of learning. DIANA is based on interactive facet-based learning principles that guide learners to reflect on their understanding of the situation and to modify and augment their understanding in response to real-time facet-specific feedback.
