What is the difference between e-health, telemedicine, and telehealth?

e-Health refers to the use of the Internet for the transmission of medical information. Telemedicine refers to the use of information and telecommunciations technologies to exchange clinical information. Telehealth (TH) is the result of that exchange. By definition, telehealth involves a separation of distance and/or time between a patient and a diagnosing or treating clinician. Telehealth technologies are generally used in three ways:

  1. To deliver health care services to patients at a distant site
  2. To educate providers, administrators, patients, and their families
  3. To accumulate data or monitor disease incidence as a part of a public health, epidemiologic, or more recently, a biodefense network
