Medical Informatics Foundations
Medical informatics foundations gather the defining concepts of health informatics: what the discipline is, how biomedical and clinical informatics are framed, how information systems are organised within health care, how people interact with health information technology, and who makes up the informatics workforce. This area orients the reader to the field before the more specialised topics of data, standards, decision support, and analytics.
Definition
Medical informatics (also termed biomedical or health informatics) is the interdisciplinary field concerned with the effective use of biomedical data, information, and knowledge for scientific inquiry, problem solving, and decision making, motivated by the goal of improving human health.
Scope
The area introduces the scope, history, and conceptual frameworks of health informatics as an applied science at the intersection of biomedical knowledge, information and computer science, and the organisation of care. It is a reference overview of the field's foundations and does not provide clinical, operational, or procurement guidance.
Sub-topics
Core questions
- What distinguishes health informatics as a discipline from the information technology it employs?
- How are the biomedical, clinical, public-health, and consumer subfields of informatics related?
- How do information systems fit into the structure and workflow of health care organisations?
- How do human factors shape whether health IT helps or harms care?
- What roles and competencies define the informatics workforce?
Key concepts
- Data, information, and knowledge hierarchy
- Biomedical informatics as an interdisciplinary science
- Subfields: bioinformatics, imaging, clinical, public health, consumer informatics
- Information systems in health care organisations
- Human factors and usability of health IT
- Informatics workforce, roles, and competencies
Clinical relevance
The foundations of informatics underpin the systems clinicians and patients use every day, from electronic health records to decision support. Understanding them supports critical reading of how health technology is designed, adopted, and evaluated; this area is orienting reference material and is not a basis for individual clinical or procurement decisions.
Evidence & guidelines
Authoritative definitions and competency frameworks for the discipline have been articulated by professional bodies such as the American Medical Informatics Association, whose board white paper specifies a working definition of biomedical informatics and core competencies for graduate education (Kulikowski et al., 2012).
History
Medical informatics took shape from the 1950s onward as computing entered medicine through hospital information systems, computer-stored medical records, and early decision-support research; Collen's history documents this trajectory in the United States, and Haux traces the parallel evolution of health information systems internationally (Collen & Ball, 2015; Haux, 2006). Over subsequent decades the field broadened from individual applications into a recognised discipline with formal definitions and educational competencies (Kulikowski et al., 2012).
Debates
- Naming the discipline: medical, biomedical, or health informatics?
- The field has been called medical informatics, biomedical informatics, and health informatics, with each label emphasising a different breadth; professional consensus has moved toward 'biomedical informatics' as an umbrella spanning molecular to population scales, while 'health informatics' remains common for applied clinical and public-health work.

Frequently asked questions
- Is medical informatics the same as health information technology?
- No. Health information technology refers to the hardware and software used to manage health information, whereas medical informatics is the discipline that studies how to use data, information, and knowledge effectively to improve health; the technology is one of its tools.
- Why does this area sit under health policy, systems, and informatics?
- Informatics is treated as part of how health systems organise and govern information, so it is grouped with the policy and systems disciplines rather than with a single clinical specialty.
