Telemedicine is a subset of telehealth, as concluded by Sood et al. in a 2007 study after analyzing 104 peer-reviewed definitions of telemedicine. Although some authors inadequately use it to describe the delivery of healthcare services at a distance only by physicians, telemedicine is distinguished from telehealth in the sense that the former focuses on the curative scope of the healthcare services by all healthcare professionals, excluding therefore the preventive and promotive aspects of healthcare as remote training, administrative and educational services.
According to Bashshur, Telemedicine involves the use of modern information technology, especially two-way interactive audio/video communications, computers and telemetry to deliver health services to remote patients and to facilitate information exchange between primary care physicians and specialists at some distance from each other (Bashshur, et al., 1997).
