1.                   Introduction

Biomedical Informatics (BMI) in the Boston area has a long tradition, with a wide variety of activity underway in laboratories at Harvard, Massachusetts Institute of Technology (MIT), as well as other universities, and at a number of hospitals affiliated with these universities.  For over a decade, the Harvard-MIT Division of Health Sciences & Technology (HST) has served as the focal point for cooperation among various BMI groups, and has been the home of a growing range of research training programs, courses, and graduate degree programs.

 

This website introduces BMI in Boston, with particular emphasis on the programs in which HST plays a coordinating role.  Since BMI is a rapidly growing and developing area, it is not possible to be comprehensive, and there are likely to be a number of Boston area activities that are not included. Further, as noted below, the definition of BMI is a very broad one.  Thus, depending on what one chooses to include under the rubric, the range of activities enumerated may differ.

1.1             Definition and scope of Biomedical Informatics

Definition: Biomedical Informatics (BMI) is the field that concerns itself with the cognitive, information processing, and communication tasks of biomedical research, health care practice, and education, including the information science and technology to support these tasks.

 

BMI is both a science and engineering activity:

§         Science: Modeling and analyzing

(1) biomedical phenomena or processes

(2) human reasoning processes applied to them

e.g., gene expression, protein structure, clinical diagnostic process, epidemic outbreak patterns, …

§         Engineering: Building of systems

(1) to organize data and knowledge

(2) to represent models or processes

(3) to perform analyses or aid human problem solving

e.g., GenBank, pharmacokinetics, clinical information systems, DXplain, virtual human, …

 

Inasmuch as biomedicine encompasses research at molecular, cellular, organ system, human, or population levels, and includes health care practice, and population-based practice such as disease prevention and public health, BMI includes informatics aspects of all of the above. 

 

The definition of BMI emphasizes the spectrum of pursuits encompassed by the field, both in terms of sources of data, problems of interest, and kinds of methods used.  The diagram below indicates (in blue) the somewhat separate areas of informatics research that have arisen in recent years, based on those distinctions. The term BMI as we use it here is meant to include all of these separate foci plus others, as well as a number of intersections among those foci (in red).


Together, these foci come closer to portraying the spectrum of BMI, and reflect the changing nature of biomedical science.   The diagram emphasizes the need to transcend artificial boundaries of nomenclature of fields, as interesting questions relate to problems at the intersections of subfields.

1.2             Underlying principles

With regard to defining a field of BMI in terms of a set of principles that form the basis for its educational content, a number of broad informatics problems are common across the various subfields, and must be addressed by similar methodologies.  Examples of these broad informatics problems and the associated methodologies are:

§         Data and knowledge representation

–  Standard vocabularies/taxonomies, structures for storage

– Methods of data and knowledge integration from distributed repositories

– to enable development of complex models and systems

§         Data analysis, presentation, and machine learning

– Modeling and simulation

–  Multi-dimensional data visualization

–  Supervised and unsupervised learning and knowledge discovery

§         Data and knowledge management

–   Tools and resources to facilitate research and education

e.g., databases, knowledge bases, tool libraries

–        User-specific problem solving environments and collaborative environments

§         Ethics, privacy, and confidentiality

–  Tools to manage security, anonymization, IRB approval, etc.

Thus, while the different areas of application of informatics encompassed by BMI have a number of specific features and requirements, there is in addition a set of core knowledge and skills that appear to be fundamental for all practitioners of BMI.

1.3              Importance of BMI in the academic medical center

A variety of factors have contributed to the growing emphasis on developing BMI centers, programs, and departments in academic medical centers. Among the most important reasons appear to be the following:

*        Changing nature of biomedical research and growth of “big science”

*        Health care delivery changes: enterprise integration, quality initiatives

*        Consumer health initiatives

*        Educational technology opportunities

*        Public health agendas

*        Issues of privacy and confidentiality and the ability to do research

*        Progress in information technology and communications as a driver

*        Business as well as research opportunities
