Definition, Scope, and History of Health Informatics

Health informatics is the interdisciplinary field that studies the effective use of biomedical data, information, and knowledge to improve health. This entry sets out how the discipline has been defined, how broad its scope is across molecular, clinical, and population levels, and how it emerged historically as computing entered medicine.

Definition

Health informatics is the interdisciplinary study of the design, development, adoption, and application of information-technology-based innovations in health care services delivery, management, and planning; in the broader 'biomedical informatics' framing it is the field concerned with the effective use of data, information, and knowledge for scientific inquiry, problem solving, and decision making, motivated by the goal of improving human health.

Scope

The topic covers working definitions of the discipline, the distinction between informatics and the technology it uses, the breadth of its subfields, and the major historical milestones from early hospital and record systems to a recognised academic discipline. It is reference material on the field's identity and origins, not technical or clinical guidance.

Core questions

• How has the discipline been formally defined, and by whom?
• What is the difference between informatics and health information technology?
• How wide is the scope of the field across biological, clinical, and population levels?
• What historical developments shaped informatics into a discipline?

Key concepts

• Working definition of biomedical/health informatics
• Data-information-knowledge distinction
• Discipline versus enabling technology
• Scope from molecular to population scale
• Historical milestones and naming evolution

Clinical relevance

A clear sense of what informatics is and where it came from helps clinicians and managers interpret claims made about health technology and place new tools in context. This entry is orienting and historical and does not direct any clinical or operational decision.

Evidence & guidelines

The American Medical Informatics Association board white paper offers a widely cited working definition of biomedical informatics and frames its scope and educational competencies (Kulikowski et al., 2012); standard textbooks consolidate the same definitional consensus (Shortliffe & Cimino, 2014).

History

Computing entered medicine in the 1950s and 1960s through hospital information systems and computer-stored medical records, with early academic programs and the coining of terms such as 'medical informatics' (from the French informatique medicale) following in the 1960s-1970s. Collen's history documents this development in the United States, while Haux traces the international evolution of health information systems; over subsequent decades the field acquired formal definitions, journals, professional societies, and graduate competencies, and its preferred umbrella name shifted toward 'biomedical informatics' (Collen & Ball, 2015; Haux, 2006; Kulikowski et al., 2012).

Debates

Medical, biomedical, or health informatics?

The discipline's name has shifted as its scope widened; 'biomedical informatics' is favoured as an umbrella spanning molecular to population scales, while 'medical' and 'health' informatics persist for clinically and system-oriented work, reflecting genuine differences in emphasis rather than mere labels.

Frequently asked questions

When did medical informatics become a recognised discipline?

Its roots lie in the 1950s-1960s as computing entered hospitals and medical records; it matured into a recognised academic discipline with dedicated societies, journals, and formal definitions over the following decades, with consensus definitions and competencies articulated by the 2010s.

Does health informatics only concern computers?

No. While information technology is central to its practice, informatics is fundamentally about the effective use of data, information, and knowledge to improve health, which includes human, organisational, and cognitive aspects alongside the technology.
