In its most general sense '''medical informatics''' (also called health informatics) is the application of information technology to healthcare. This is, of course, a very broad field, but at present, the term informatics has come to be used in a more narrow sense as referring to:

*The organization and representation of information in healthcare
*The development and use of [[controlled vocabulary|controlled vocabularies]] in healthcare and computer systems used in healthcare
*More generally, the development and use of [[ontology|ontologies]] as an aid to managing health related information
*Clinical decision support, both as a theoretical and a practical (engineering) problem

Another important area of study is patient record systems and, in particular, the electronic health record (EHR). This is an area that poses a number of technical challenges, but issues such as [[usability]], [[patient safety]] and [[privacy]] are obviously of paramount importance. Another interesting area is mobility and portability of information. Obviously, in critical care situations it is highly desirable to have access to information that may not be maintained locally (such as adverse reactions), but making this information available raises significant privacy concerns. It also poses a number of technical challenges because systems that are developecd independently may use very disimilar means of representing and storing information. Health information systems must also be convenient to use, and sufficiently comprehensive to be of value to health care providers. If they do not add value to traditional means of information management (such as [[Paper chart|paper charts]], they are unlikely to be used.
