Ehealth is a word used to characterize not only “Internet medicine”, but also virtually everything related to computers and medicine. According to Intel, e-health is “a concerted effort undertaken by leaders in healthcare and hi-tech industries to fully harness the benefits available through convergence of the Internet and health care” .
According to the WHO “e-Health is the cost-effective and secure use of information and communications technologies in support of health and health-related fields, including health-care services, health surveillance, health literature, and health education, knowledge and research.
Clinical research is now becoming increasingly dependent on ‘the computer’ and the role played by it in the field of e–medicine is many folds, in fact we can say that the following ten points and also the eleventh are key deciders when it comes to conducting treatments on patients who may be staying across international boundaries by making knowledge available to both the patient and the doctor The knowledge which may otherwise not be available to both through traditional methods. Clinical research and its data filed in e–books are got by both the patient and the physician by just a click of the mouse thus expert opinion is no longer a mirage it is within everyone’s reach.
Clinical scientists can be classified under two heads the biomedical scientist and the Clinical Laboratory scientist. The Biomedical scientist plays a very important role in day to day medical procedures They carry out tests to support the diagnosis and treatment of diseases eg: they carry out blood tests for blood grouping etc at the time of surgical procedures specially in emergency cases like accidents or heart attacks where it would become impossible to carry out the treatment in the absence of the knowledge about the patient’s blood group Cancer Diabetes, meningitis hepatitis, and even Aids also require biomedical scientist to help in screening, diagnosing and treating the patient.
