Enrico’s viewEnrico’s view
If physiology literally means 'the logic of life', and pathology is 'the logic of disease', then medical informatics is the logic of healthcare.
It is the rational study of the way we think about patients, and the way that treatments are defined, selected and evolved.
It is the study of how medical knowledge is created, shaped, shared and applied

Health or Medical Health or Medical InformaticsInformatics
The terms 'medical informatics' and 'health informatics' have been variously defined, but can be best understood as the understanding, skills and tools that enable the sharing and use of information to deliver healthcare and promote health. 'Health informatics' is now tending to replace the previously commoner term 'medical informatics', reflecting a widespread concern to define an information agenda for health services which recognises the role of citizens as agents in their own care, as well as the major information-handling roles of the non-medical healthcare professions.

Health informatics is concerned with the systematic processing of data, information and knowledge in
medicine and healthcare. The domain covers computational and informational aspects of processes and structures, applicable to any clinical or managerial
discipline within the health sector whether on a tele (remote) basis or not. Health informatics is delivered by operational health practitioners, academic researchers
and educators, scientists and technologists in operational, commercial and academic domains
