Because many of the Veterans Administration hospitals in Appalachia are located great distances from medical teaching facilities, high powered communication satellites have been employed to facilitate quality two-way communication between medical personnel scattered throughout the region. To achieve diagnostic, therapeutic, and educational purposes, the National Aeronautics and Space Administration's (NASA) Applications Technology-6 satellite was field tested in five different modes: (1) video seminars; (2) teleconsultations; (3) grand rounds; (4) out-patient clinics; and (5) computer-mediated events. All five modes provided clear communication and significantly altered the climate of the ten hospitals involved in the experiment. The video seminars were particularly well received. Details of the program evaluation are provided. (EMH)
