eHealth (also written e-health) is a relatively recent term for health care practice which is supported by electronic processes and communication, some people would argue the term is interchangeable with Health care informatics. However, the term e-health encompasses a whole range of services that are at the edge of medicine/healthcare and information technology:

1) Electronic Medical Records: enable easy communication of patient data between different healthcare professionals (GPs, specialists, care team, pharmacy)

2) Telemedicine: includes all types of physical and psychological measurements that do not require a patient to travel to a specialist. When this service works, patients need to travel less to a specialist or conversely the specialist has a larger catchment area.

3) Evidence Based Medicine: entails a system that provides information on appropriate treatment under certain patient conditions. A healthcare professional can look up whether his/her diagnosis is in line with scientific research. The advantage is that the data can be kept up-to-date.

4) Citizen-oriented Information Provision: both healthy individuals and patients want to be informed on medical topics.

5) Specialist-oriented Information Provision: e.g. in an overview of latest medical journals, best practice guidelines or epidemiological tracking.

6) Virtual healthcare teams: consist of healthcare professionals who collaborate and share information on patients through digital equipment (for transmural care).
