The Journal of Medical Internet Research has an interesting article about the currently available (published) definitions for "eHealth" (e-Health).

That article, by Hans Oh et al., is named: What Is eHealth - A Systematic Review of Published Definitions

From the article abstract:
Context: The term eHealth is widely used by many individuals, academic institutions, professional bodies, and funding organizations. It has become an accepted neologism despite the lack of an agreed-upon clear or precise definition. We believe that communication among the many individuals and organizations that use the term could be improved by comprehensive data about the range of meanings encompassed by the term."
Objective: To report the results of a systematic review of published, suggested, or proposed definitions of eHealth."
Conclusions: The widespread use of the term eHealth suggests that it is an important concept, and that there is a tacit understanding of its meaning. This compendium of proposed definitions may improve communication among the many individuals and organizations that use the term.
