Telemedicine, the use of bidirectional telecommunications systems for the delivery of health care at a distance, could create a more equitable distribution of medical care. Many medical tasks can be performed at a distance although some require the presence of a physician's assistant. Cost-benefit analysis of this service is difficult and requires further study. The legal issues involved and the psychological effect of telecommunication must also be considered in planning telemedicine programs. Potential future impacts of telemedicine are identified along with recommendations for future research activity and regulation in this field. (Author/PF)
