Abstract. The traditional system of clinical education in emergency medicine relies on practicing diagnostic, therapeutic, and procedural skills on live patients. The ethical, financial, and practical weaknesses of this system are well recognized, but the alternatives that have been explored to date have shown even greater flaws. However, ongoing progress in the area of virtual reality and computer-enhanced simulation is now providing educational applications that show tremendous promise in overcoming most of the deficiencies associated with live-patient training. It will be important for academic emergency physicians to become more involved with this technology to ensure that our educational system benefits optimally. Key words: virtual reality; simulation; emergency medicine; education. ACADEMIC EMER-GENCY MEDICINE 2002; 9:78-87 T HE INFORMATION age is here and, in an unprecedented fashion, is changing nearly every aspect of our lives. Astoundingly, this evolution promises to accelerate as computer-related advances continue to become available at an exponential rate. Gordon Moore, the cofounder of Intel Corporations, has observed that the power of computer chips doubles every 18 to 24 months. And, Randall Tobias, a former vice-president of ATT, noted that ''over the last 30 years, we have seen a 3,000-fold increase in computing power. If we had had similar progress in the automotive industry, a Lexus would cost $2, it would travel at the speed of sound and go 600 miles on a thimble full of gas.'' 1 Almost every profession has learned to adapt to and subsequently exploit this ongoing progress in computing technology. The field of medicine, however, has only just begun to join in and is doing so at a considerably slower pace. The leaders in medical education, in particular, have not taken advantage of the technology that is becoming available, and those of us in emergency medicine (EM) are no exception. In EM, as in many other specialties, the traditional training model still exists; for diagnosis, therapeutic intervention, and performing procedures, the live patient remains the cornerstone for teaching. Over the years, many educators have understood there to be significant drawbacks to this system and have searched for other options. These other training tools, including volunteers, plastic models, animals, and cadavers, have shown even greater flaws.2,3 So today, believing there to be no acceptable alternatives, we continue to rely on the patient as the foundation of our clinical education. However, the continuing progress of computing technology is providing us with applications that will challenge this notion and quickly make it outdated. Advances in the realms of virtual reality and computer-enhanced simulation are showing great promise in supplementing our traditional training system of live ''models,'' and may even eventually replace them.
