Telemedicine is the use of telecommunication and information technologies in order to provide clinical health care at a distance. It helps eliminate distance barriers and can improve access to medical services that would often not be consistently available in distant rural communities. It is also used to save lives in critical care and emergency situations. Although there were distant precursors to telemedicine, it is essentially a product of 20th century telecommunication and information technologies. These technologies permit communications between patient and medical staff with both convenience and fidelity, as well as the transmission of medical, imaging and health informatics data from one site to another. Early forms of telemedicine achieved with telephone and radio have been supplemented with videotelephony, advanced diagnostic methods supported by distributed client/server applications, and additionally with telemedical devices to support in-home care. == Disambiguation == The definition of ''telemedicine'' is somewhat controversial. Some definitions (such as the definition given by the World Health Organization〔http://www.who.int/goe/publications/goe_telemedicine_2010.pdf〕) include all aspects of healthcare including preventive care. In other cases the definition of Telemedicine is limited to include the provision of clinical services only, with similar expressions such "telehealth" and "eHealth", being used to denote broader definitions of remote healthcare not always involving active clinical treatments.〔 The term eHealth is often used, particularly in the U.K. and Europe, as an umbrella term that includes telehealth, electronic medical records, and other components of health information technology. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Telemedicine」の詳細全文を読む スポンサード リンク
