The National Aeronautics and Space Administration (NASA) has been a pioneer
in telemedicine since the beginning of the human spaceflight program in th
e early 1960s. With the rapid evolution in computer technology and equally
rapid development of computer networks, NASA and the Department of Surgery
in Yale University's School of Medicine created a telemedicine testbed with
the Russia Space Agency, the Spacebridge to Russia Project, using multimed
ia computers connected via the Internet. Clinical consultations were evalua
ted in a store-and-forward mode using a variety of electronic media, packag
ed as digital files, and transmitted using Internet and World Wide Web tool
s. These systems allow real-time Internet video teleconferencing between re
motely located users over computer systems. This report describes the proje
ct and the evaluation methods utilized for monitoring effectiveness of the
communications. The Spacebridge to Russia Project is a testbed for Internet
-based telemedicine. The Internet and current computer technologies (hardwa
re and software) make telemedicine readily accessible and affordable for mo
st health care providers. Internet-based telemedicine is a communication to
ol that should become integral to global health care.
