I agree that eHealth, as documented in an article by T.Shaw, et al., is divided into 3 domains; health in our hands, interacting for health, and data enabling health.
In my opinion, eHealth is more than just about health and technology. It is an intervention to improve health care physically, mentally, and socially for both patients and healthcare professionals by using information and communication technology. With eHealth, healthcare professionals are able to get connected with their patients easily and deliver good healthcare services. Patients could have more understanding of their health conditions and take good care of themselves. Healthcare professionals are able to consult and advise each other as needed. Health education could also be provided to both patients and healthcare professionals to gain more knowledge on health.
