Cardiology patient simulator and computer-assisted instruction technologies in bedside teaching.

The design and uses of an innovative technology-based approach which addresses critical problems with bedside teaching during ward rounds in the current health care situation are described. A cardiology patient simulator (HARVEY) and an accompanying computer-based interactive laserdisk system provide medical students, house officers and other health professionals with the opportunity to encounter a wide variety of clinical problems for learning and assessment. A group of cardiologists and medical educators from a consortium of US medical schools has guided the development and formal assessment of the entire system over the past 10 years. The system and simulator can be configured and programmed to provide appropriate heart sounds, laboratory data, and test results upon request; hands-on experience to practise examination skills is also available. The system, whole or in part, can be used in a variety of instructional modes from self-instruction to demonstration teaching, and from self-assessment to the final clinical examination. The system's effectiveness for teaching medical clerks is summarized, as is its use in providing continuing education for primary care doctors in rural practice.
