Field of information science concerned with the analysis and dissemination of medical data through the application of computers to various aspects of health care and medicine. Medical Subject Heading (MeSH) — National Library of Medicine
‘Health informatics is the logic of healthcare.’ Prof. Enrico Coiera, Guide to Health Informatics , 2nd Edition
“The role of the information sciences in medicine continues to grow, and the past few years have seen informatics begin to move into the mainstream of clinical practice. The scope of this field is, however, enormous. Informatics finds application in the design of decision support systems for practitioners, in the development of computer tools for research, and in the study of the very essence of medicine – its corpus of knowledge. The study of informatics in the next century will probably be as fundamental to the practice of medicine as the study of anatomy has been this century.” (Source: Coiera E (1995) Medical Informatics , BMJ, 1995;310:1381-7)
The terms ‘medical informatics’ and ‘health informatics’ have been variously defined, but can be best understood as meaning 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… — British Medical Informatics Society
Health Informatics is concerned with the study of the principles of information processing and with the provision of (general) solutions for information processing problems in the field of health care; uses appropriate (formal) methods and tools, especially from informatics, to model structure and mechanism information processing systems in the field of health care in order to describe or analyze these systems or in order to provide possibilities for their construction or for their evaluation.

“…Informatics is an emerging discipline that has been defined as the study, invention, and implementation of structures and algorithms to improve communication, understanding and management of medical information. The end objective of biomedical informatics is the coalescing of data, knowledge, and the tools necessary to apply that data and knowledge in the decision-making process, at the time and place that a decision needs to be made. The focus on the structures and algorithms necessary to manipulate the information separates Biomedical Informatics from other medical disciplines where information content is the focus.” (Source: Aamir M.

Informatics: “The use of information systems, computer technology and telecommunications to improve patient care, research and education.” (Source: Westmead Hospital, Westmead, N. S. W. Australia
Health Informatics examines areas such as health concepts, ontologies, classifications, terminologies, (health) knowledge managment methodologies and algorithms, electronic health record storage and delivery structures, health messaging and communication systems (including visual and auditory), decision support systems, and much more. Related topics such as the human-computer interface, ethical and legal impacts, consumer access, security and privacy as well as many ethical issues are part of the health informatics domain. Evans, D. 2003.
In 2008 Intel Corporation’s chief technology officer speculated on the possibility that machines “could even overtake humans in their ability to reason in the not so distant future” (Rattner, 2008) which as we move through 2010 the paucity of ‘reasoning’ decision support toools should give some concern to those working in health care who desire to move through the muddled complexity of current systems to a point where clinical systems reasoning for the future will become the arbiter of care in clinical information and decision support systems.

The notion of making a mistake is so engrained in the human psyche that the study and practice of preventing a mistake is an industry in its own right. An industry which paradoxically also makes mistakes. Mistakes are quite simply unintentional errors or misunderstandings usually (but not always) associated with a potential or real adverse or negative outcome for someone or something. History is littered with large demonstrable mistakes with little or no impact on humankind but equally there are events where small errors of judgement that have led on to catastrophic outcomes.
The rush to embrace Clinical Information Systems in the heath care environment has as one of its drivers a reduction in adverse clinical events. The design of clinical systems is often more dependent on underlying operating software, vendor preferences, legacy system economies and less with ensuring that clinicians, often in highly stressful situations, do not make errors when interacting with systems.
Such errors leading on to new adverse outcomes that the implementations were intended to reduce in the first place. There are a multitude of points of interaction where design may be critical including graphical presentation, icon design and placement, standardisation of terminologies and screen actions, physical environment, interface tool design, warnings and alerts.
There are also less obvious sources of error including the increasing push for deeply embedded decision support algorithms that may as they become hidden from the clinician increase the opportunities for misinterpretation and poor outcomes.
This site explores analogies with non-clinical design process errors, anecdotal observations and reviews recent human factor research to suggest future health informatics research directions in applying human factors and systems designs through encouraging standardised clinical interface development based on evidence and analysis of errors as well as to suggest the need for greater uses of standardised interfaces across vendors.
