Is telemedicine a subset of medical informatics?

Informatics has a key characteristic of a new discipline in a technically transient environment-there is no universal definition of it. This is not surprising, given its complex and diverse nature. In a broad sense informatics is the interface between developing technologies and the decision sciences, in particular clinical sciences. Telemedicine has no universally accepted definition either. Telemedicine requires the use of electronic communication networks for the transmission of information and data related to the diagnosis and treatment of, as well as education about, medical conditions. The debate ensues over whether it is or is not a subset of medical informatics. The care of the elderly diploma programme is a telemedicine project within the department of family medicine at the University of Alberta; it is a distance learning programme directed towards educating and training physicians in rural Alberta. This project provided us with the practical experience of addressing both informatics and telemedicine issues jointly.
