Definitions for terminologies that describe digital health and care at a distance

	Description
eHealth	The cost-effective and secure use of information and communication technologies in support of health and health-related fields, including healthcare services, health surveillance, health literature and health education, knowledge and research
Telemedicine	The practice of medicine using technology to deliver care at a distance, whereby a HCP in one location uses a telecommunications infrastructure to deliver medical care to a patient at a distant site. Telemedicine may involve synchronous or asynchronous consultation using information and communication technology. The scope of telemedicine includes: telemonitoring (see below), tele-expertise, tele-assistance, tele-visit, teleconsultation and tele-education
Telemonitoring	The use of information and communication technology to monitor, transmit and share information between geographically separated individuals that relates to the health status of a patient. Telemedicine allows care of patients at home or at other locations remote from their HCPs, using external telecommunication devices and infrastructure, such as mobile phones and tablet computers, desktop computers, using broadband or digital cellular networks. The use of CGM systems to monitor glycaemic metrics is an example of telemonitoring
mHealth	Mobile health is a subsegment of eHealth by which medical and public health practices are directly supported by mobile devices. It particularly includes the use of mobile communications devices for delivering health and well-being information and services, as well as mobile health applications. Smartphone apps for reading and reporting glucose-sensor data are established examples of mHealth
