Telemedicine, the delivery of health care with the patient and health
professional at different locations, has been around for over 30 years
. Its driving force has been developments in communications technology
, and as new communications systems are developed health applications
are proposed such as supporting the delivery of primary health care to
geographically remote areas or regions underserved through the maldis
tribution of professional expertise. Despite rapid technological advan
ces, evaluations of such systems have been largely superficial, and mo
re thorough evaluations have failed to show significant advantages for
more advanced and expensive technology over older technology such as
the telephone. Methods for evaluating the impact of particular technol
ogies on the health care system need to be developed and clearer benef
its shown in terms of improved standards of care.
