The domain of medical informatics has evolved fast since the early 90ies. Until that moment there had been many developments in information systems to support the infrastructure of medicine. Gradually the awareness emerged that medical doctors and other health care professionals (including managers) needed support in education, decision making, communication and other professional activities. As the focus shifted to information management of the health care professionals, the discipline of 'medical informatics' took further shape.
"Medical informatics is the field that concerns itself with the cognitive, information processing, and communication tasks of medical practice, education, and research, including the information science and the technology to support these tasks."
The field is very much interdisciplinary, with branches of high applied activities and also involved in fundamental research. Medical informatics currently is a distinct academic entity in most countries, with a strong network between EU countries in particular. And the focus is on medical practice.
The domain of public health informatics seems not yet so clearly defined in the EU. Most of the time, IT in public health (e.g. supporting new surveillance systems), follow standards defined within medical informatics (e.g. standards such as LOINC, SNOMED, HL7).
Where medical informatics comes from a predominantly patient oriented focus, it follows that choices in IT architecture, standards, protocols etc have been made from that perspective (e.g. high requirements for confidentiality. data protection, and accuracy of information of individual diagnostics and diagnosis).
Key requirements from the public health perspective focus on populations rather than individuals and may include timely data access (which can conflict with decisions for data shielding in medical informatics systems) and representativeness for (sub)populations (e.g. high focus on getting continuous and unbiassed samples of information on subpopulations; accuracy of information on individual diagnosis would be much less important). These key requirements could (and probably should) lead to appropriate choices for IT architecture that may be different from those in medical informatics.
Therefore there is a need for building and maintaining a critical mass of public health information experts, that are well versed in core activities of public health (e.g. surveillance, outbreak investigations, field epidemiology, public health microbiology, screening) and who are able to use that knowledge in developing IT infrastructure that serves the needs of public health profesionals and that is well integrated in health care systems.
"Public health informatics is the systematic application of information and computer science and technology to public health practice, research, and learning."
The USCDC has developed a 2 year fellowship in public health informatics, with the goal to provide training and experience in applying computer and information science and technology to real public health problems. In the EU, the public health informatics is not yet coordinated at the Community level in either development of professional standards or training.

These are my current thoughts and views on the topic. I would appreciate feedback very much, in order to strengthen the vision of public health informatics as an entity.
