Harnessing the power of information technology to improve health
status both of individuals and of populations is claiming unprecedented
attention nationally and internationally as society deals with the effects
of recent economic, environmental and policy change. Health informatics is
the relatively new, interdisciplinary field that has evolved to bring expertise in
information science and technology to the medical and biological knowledge
base. The recent, rapid growth of health informatics, along with its natural
connection to information science, increases its relevance to readers of the
Bulletin of the American Society for Information Science and Technology, as
well as to prospective students who are considering health informatics as a
career choice. This brief article will define and describe the field, identify
educational pathways and provide some resources regarding career options,
professional associations and other resources that readers may find useful.
What Is Informatics?
Any discussion of the field must begin by clarifying what is meant by
informatics, and in particular, health informatics. Although the literature of
health informatics can be traced as far back as the 1970s, interest increased
during the 1980s [1]. It has been international in scope from its outset, with
programs in Europe recognized as early leaders. Also, in Europe, the term
informatics has not been so tightly tied to a specific domain as it has in North
America. Here, informatics is generally used in conjunction with a specific
domain such as health or biomedicine – or to other fields such as law,
resulting in terms such as health informatics,biomedical informatics or legal
informatics. (An allied field known as social informatics is not domain
specific and refers to the socio-technical aspects of information and
communications technologies.)

EDITOR’S SUMMARY
The area of health informatics applies information science methods to analyze and
understand health care information, to progress from raw data to knowledge, for improved
problem solving, decision-making and care delivery. With the field still relatively young and
subspecialties already branching off, the terminology and scope continue to evolve. The
fundamental model is shifting from treatment of an illness to wellness and disease
prevention and viewing an individual’s daily life in the broad context of factors that
influence health. As the field takes shape, professional education is typically originating in
health education for the informatician or in information science and technology for the
health informaticist, with complementary coursework to expand understanding of and
competency in the interdisciplinary field. The rapid growth and high demand for health
informatics is stimulating an expansion of educational opportunities with degrees at all
levels both in the United States and at international institutions. Conferences, professional
publications and online resources on the topic multiply, serving those interested in making
health informatics a career.
KEYWORDS
medical informatics interdisciplinarity
emerging disciplines trends
biomedical information education
Health informatics – sometimes called healthcare informatics – is
complemented by related fields that have overlapping areas of focus. For
instance, biomedical informatics is the term preferred by AMIA, one of the
leading associations founded primarily by physicians (www.amia.org). The
authors of a well-known text use this term to refer to “the scientific field
that deals with biomedical information, data and knowledge – their storage,
retrieval and optimal use for problem solving and decision-making.” [2]
They situate biomedical informatics as it relates to biological science and
medical practice. Others, such as HIMSS, the Healthcare Information
Management and Systems Society (www.himss.org) use the term health
informatics to situate the field as it relates to health care, going beyond the
practice of medicine to include public health, nursing and consumer health.
Yet another related term is bioinformatics, which refers to the application of
computer technology to the biological sciences to acquire, organize, store,
analyze and visualize biological data to expand their use [3]. Clinical
informatics has emerged as a term to describe the application of informatics
to problems in clinical care, usually by physicians. Finally, the term health
information management usually refers to the management of health data
and information that is captured in medical or health records. Now that such
records are increasingly electronic, the field of health information
management overlaps some aspects of health informatics. The leading
society for health information management is AHIMA (www.ahima.org).
Despite the differences in terminology and scope, all of these fields refer
to the informatics pyramid [Figure 1] where the relationship among data,
information and knowledge is displayed. The informatics pyramid illustrates
the relationship between data and information and how they can be
transformed into the creation of knowledge that is applied to make decisions
and solve problems. Informatics thus encompasses the principles and
processes through which data is transformed and applied to problems in a
domain of interest.
In addition to the varying definitions of the field, the terminology used to
describe the professional worker differs, too. The term informatician has been
the term of choice for practitioners who come from the biomedical domain,
while informaticist is most often used by those whose roots are in nursing
or other health
professions.
Whether they
are called
informaticians or
informaticists, those
who study and
practice informatics
are quick to point
out that their
expertise extends
well beyond that of
information technology to encompass both knowledge of and appreciation
for the domain in which they practice and for the needs of their constituents.
A Rapidly Evolving Environment
The environment surrounding health and biomedicine is evolving at a
rapid pace. The medical model in which patients who have diseases are
treated in episodic encounters with physicians is no longer the dominant one;
rather, the term health implies an approach in which the goal is as much
disease prevention as it is disease treatment. In the health model, activities
and decisions are embedded in the context of daily living; thus, informatics
problems are not solely those arising from healthcare practice, but also those
that arise from the needs of individuals in their social environments. This
shift suggests greater opportunities for those who are interested in topics such
as eHealth and health information literacy that draw upon the intellectual
traditions of information science, computer science and public health.
While much of the current focus of health informatics is on clinical
issues such as the design and implementation of electronic health records
and decision support, the field includes medical ontology construction as
well as information organization, storage and retrieval, artificial intelligence,
text mining, data exchange, data standards and natural language processing
in addition to security and privacy. The related field of bioinformatics also
includes data curation and modeling.

Education for Informatics
Formal education in informatics occurs at multiple levels – baccalaureate,
master’s and doctoral; however, there are also some training programs at the
community college level aimed at preparing workers to perform technical
duties under the supervision of a professional. A typical academic program
consists of coursework in information science plus at least one health or
biomedical domain. A strong computational emphasis is present throughout
the curriculum, and most programs require either a practicum or a research
project or both. Programs are usually structured to accommodate two types
of prospective students: those coming from a health or medical profession
seeking knowledge and skills in information science and technology or those
who possess knowledge and skills in information science and technology
but whose background does not include preparation in the health sciences.
Students are expected to select courses so they can acquire sufficient
understanding to work effectively in multidisciplinary teams and to function
as boundary spanners or translators between biomedical and health domains
and IT. Indeed, one of the benefits of an education in health informatics is the
opportunity to interact with professionals from diverse backgrounds, thereby
gaining an appreciation for the varied perspectives, vocabularies and values of
each domain which, if not addressed, can be a barrier to arriving at a solution
to a problem. One example of divergent vocabularies emerged in a course in
which one of the students, a nurse, contacted the professor about three weeks
into the course. She commented, “I suddenly recognized the challenges
inherent in health informatics when I realized that “HIT” refers to “health
information technology,” not “hemolytic idiopathic thrombocytopenia!”
The Challenge of an Interdisciplinary Field
Finding solutions to today’s health problems – ranging from drug
development to consumer health – requires insight and talent from multiple
fields. Addressing these needs requires deliberate consideration of the ways in
which domain knowledge or “context” is best acquired through the educational
process. Interdisciplinary programs administered across academic departments
bring diverse perspectives together to determine course content, admissions
standards and degree requirements. Despite the fact that interdepartmental
academic programs can be fraught with administrative barriers, almost a
third (30%) of medical and health informatics programs in the United States
are interdepartmental [4]. The interdisciplinary nature of informatics is also
reflected in recent statements by organizations ranging from the ACM
(Association for Computing Machinery) to the American Nurses Association
(ANA), each of which emphasizes the necessity of a broad-based approach
to contemporary issues [5, 6].
The interdisciplinary character of health informatics may explain why a
recent review of the literature identified more than two dozen published lists
of competencies [7]. Though these competencies vary widely in their level
of specificity, clearly some have been developed with the expectation that
they will be used to credential practitioners. For example, clinical informatics
is likely to become recognized as a sub-specialty by the American Board of
Medical Specialties in the near future, while a certification exam is offered
to nurses through the American Nurses’ Credentialing Center
(www.nursecredentialing.org/) [8]. Program accreditation at multiple levels
is available through CAHIIM (Commission on Accreditation for Health
Informatics and Information Management Education), but uptake among
master’s level programs has been relatively slow (www.cahiim.org/).
Informatics education has recently undergone a growth spurt in the
United States, and according to a 2008 survey, courses of study leading to
degrees at several levels are offered by over 175 institutions in the United
States [4]. This number has likely increased in the intervening interval
because of the perceived need for an increased workforce needed to meet
the 2014 electronic health record mandate. When programs outside the
United States are included, the number likely approaches 200. Informatics
education occurs throughout the world, although most programs are located
in North America and Western Europe. There are several lists where
prospective students can identify informatics programs of study. Programs
located in institutions that are members of AMIA’s Academic Forum are
listed at www.amia.org/inside/initiatives/acadforum/members.asp; a list of
medical informatics programs worldwide that is current through the end of
2010 is at www.hiww.org/se.html. The International Medical Informatics
Association is the “association of associations” and provides additional

Is Informatics for You?
U.S. News and World Report named health informatics as among the top
10 “ahead of the curve” careers in 2007 [9]. Given the pressure on the
healthcare sector to adopt information technology to reduce errors and become
more efficient and effective, it is likely that prospects for employment in
health informatics will continue to be favorable. Because informatics is an
emerging field, most informaticians have migrated from other careers; the
field comprises physicians, computer scientists, librarians, systems analysts,
information professionals, pharmacists and nurses. Successful informaticians
integrate their previous experience with their new knowledge and skills while
being willing to move beyond their comfort zone and take on new challenges.
Informaticians must be flexible and innovative broad thinkers who are able
to analyze problems from multiple perspectives. Those who enter health
informatics from the library and information sciences will find that their
knowledge of information organization and database structures will serve
them well, as will their grounding in user-centered information systems and
the construction and use of information standards. Learning more about how
health care is organized and delivered, the barriers and facilitators for acquiring
and applying data, information and knowledge in medical decision-making
and the sources of data from the molecular to the population level provide the
student of informatics plenty of opportunity to engage their intellectual energy.
To begin exploring this field, it is wise to attend one or more professional
conferences to network and become acquainted with the field. There are
numerous professional societies that hold conferences. Some of them have
been mentioned already, including AMIA, AHIMA, HIMSS and IMIA.
ASIS&T has an active health informatics group. ACM’s SIGHIT has recently
launched an annual symposium that is beginning to attract attention in health
informatics (www.sighit.org/).
There are other ways to acquire additional knowledge about health
informatics as a career. A quick search of PubMed will identify well over 50
scholarly journals in health informatics. While there are many good quality
health informatics blogs and twitter feeds, the Office of the National
Coordinator for Health Information Technology is a primary site for
remaining abreast of the current drivers in health informatics (http://health
it.hhs.gov/portal/server.pt/community/healthit_hhs_gov_home/1204). As
technology continues to make inroads into health care at all levels, an
abundance of interesting problems await solutions. The number and variety
of these opportunities, as well as the knowledge that your work is helping
people lead healthier lives, makes health informatics a very rewarding career. ■
