established connection between the end points that are communicating. The IP address of a videoconferencing system is its phone number.

Mobile telehealth (mHealth) is the provision of health care services with the assistance of a van, trailer, or other mobile unit in which the health care provider might provide patient services at a distance from a normal medical facility. Services may also be provided through mobile technologies that allow a mobile vehicle equipped with medical technologies to attach to an existing health care facility.

Originating site is defined by CMS as where the patient and/or the patient’s physician is located during the telehealth encounter or consult. Other common names for this term include spoke site, patient site, remote site, and rural site.

Remote patient monitoring is the use of devices to remotely collect and send data to a monitoring station for interpretation.

Spoke site, see originating site.

Store and forward (S&F) is a type of telehealth encounter or consult that uses still digital images of a patient for the purpose of rendering a medical opinion or diagnosis. S&F also includes the asynchronous transmission of clinical data from one site (e.g., patient’s home) to another site (e.g., home health agency, hospital, clinic).

Telemedicine and telehealth both describe the use of medical information exchanged from one site to another via electronic communications to improve the patient’s health status. Although evolving, telemedicine is sometimes associated with direct patient clinical services and telehealth is sometimes associated with a broader definition of remote health care services.

Videoconferencing is the real-time, generally two-way transmission of digitized video images between multiple locations; this uses telecommunications to bring people at physically remote locations together for meetings.
