Telehealth is a form of e-Health that uses telecommunications and information technologies to provide healthcare services over distance and/or time, to include diagnosis, treatment, public health, consumer health information, and health professions education. This may be done through real-time or asynchronous exchange of complex data (video, images, audio, etc).


Telemedicine is that aspect of telehealth that encompasses all those interactions between a health care provider or their surrogate and a patient where there is a geographic and/or temporal separation.

Types of telemedicine:

  • Teleconsultation is real time treatment analogous to an office visit;

  • Store and Forward images are acquired at many different sites of care, stored in an information system, read and interpreted at other, sometimes remote sites by radiologists who then record their findings in the same system for others to view and use. Used mostly in radiology, pathology and, increasingly, dermatology;

  • Direct Asynchronous Communication is communication between the provider and patient (example: email or secure messaging systems) where there is an exchange of text messages.

Exchange of information, using standards, between two parties for health or health care activities. Example transactions include:

  • New prescription message (NEWRX) from a prescriber to a pharmacy

  • A single lab order (ORC) from a primary care provider to the laboratory
