Interactive telecardiology for the evaluation of heart murmurs in children.

OBJECTIVE: To study the accuracy, patient satisfaction, and cost of telecardiographic evaluations of pediatric patients. MATERIALS AND METHODS: Patients referred to a rural pediatric cardiology outreach clinic were examined in person by a pediatric cardiologist. A second pediatric cardiologist who had no knowledge of the findings of face-to-face examination reevaluated the same patients utilizing a 768-Kbps telemedicine system. Any additional testing was performed by personnel who had no knowledge of the face-to-face evaluation. The main outcome measures included the final cardiac diagnosis, frequency of additional tests such as electrocardiography, (ECG) echocardiography (ECHO), and patient satisfaction. RESULTS: The diagnosis was agreed upon in 19 of the 21 patients studied. Two patients with small ventricular septal defects were missed during the telemedicine evaluation. The utilization rates of additional studies for both the face-to-face cardiologist and the telemedicine cardiologist were not significantly different. Patient satisfaction with the telemedicine encounter was good. CONCLUSIONS: Telemedicine appears to be effective and useful for the cardiac evaluation of pediatric patients. In spite of high data-transfer rates, differences between telemedicine and face-to-face patient encounters were observed.

Telemedicine expanding the scope of health care information.

The definition of health information is growing to include multimedia audio, video, and high-resolution still images. This article describes the telemedicine program at East Carolina University School of Medicine, including the telemedicine applications presently in use and the virtual reality applications currently under development' Included are the major design criteria that shape the telemedicine network some of the lessons learned in developing the network, and a discussion of the future of telemedicine, including efforts to incorporate telemedicine within a fully integrated health information system.

Telemedicine and distributed medical intelligence.

Recent trends in health care informatics and telemedicine indicate that systems are being developed with a primary focus on technology and business, not on the process of medicine itself. The authors present a new model of health care information, distributed medical intelligence, which promotes the development of an integrative medical communication system addressing the process of providing expert medical knowledge to the point of need. The model incorporates audio, video, high-resolution still images, and virtual reality applications into an integrated medical communications network. Three components of the model (care portals, Docking Station, and the bridge) are described. The implementation of this model at the East Carolina University School of Medicine is also outlined.
