Definitions of EHealth

nJournal of Medical Internet Research
Ehealth is an emerging field in the intersection of medical informatics, public health and business, referring to health services and information delivered or enhanced through the Internet and related technologies. In a broader sense, the term characterizes not only a technical development, but also a state-of-mind, a way of thinking, an attitude, and a commitment for networked, global thinking, to improve health care locally, regionally, and worldwide by using information and communication technology.

Europe’s Information Society
ICT for Health (also known as EHealth) describes the application of information and communications technologies across the whole range of functions that affect the health sector, from the doctor to the hospital manager, via nurses, data processing specialists, social security administrators and - of course - the patients.

I  prefer to define E-Health as:
“The synergy of communication technologies,
 information technologies and Healthcare activities that
Result in a positive outcome in Healthcare.”
