This paper has been adapted from an oral presentation to the current
written form. Much of Section II follows the PowerPoint outline format
with some expanded thoughts and brief descriptions.
Health Informatics: A Peek into the Future
Purpose: The purpose of this paper is to provide an overview of
the field of health informatics and to familiarize the readers with some
of the uses and implications of the latest developments in health technologies
for our professional and personal lives.
Goals:
- familiarize the reader with the basic concepts, terms, and definitions
of health informatics
- describe several technologies and applications that can be applied
to health, physical education, and medicine
- identify trends that have influenced the development and diffusion
of health and technology
- discuss current developments in the United States, South America,
and Venezuela
- discuss the implications of these developments and the ramifications
for the future of health and medicine
- identify sources and resources for individuals who want to explore
health informatics in greater detail.
I Introduction
I am extremely excited and honored to have been selected to submit a
paper on this topic for several reasons. I am thoroughly convinced that
the developments and advances in health informatics that have occurred
over the last decade will have a profound impact on the future of healthcare
and education. Moreover, in the next millennium health technologies will
become fully integrated into every aspect of our personal and professional
lives. Finally, no other tool at our disposal has the potential to make
such a profound impact on healthcare costs, program delivery, and quality
of life.
The purpose of this paper is to challenge the reader to think, question,
and dream about the future of our professions and how the developments
of these emerging technologies can be incorporated into our lives and
work. Only if we seek, explore, and think outside of the traditional paradigms
can we realize the true potential of these potent and powerful tools.
I do not believe that technology is a panacea or a solution for all
of our problems. Technology is only a tool. The secret of using any tool
is to be able to select the right tool for each job. But first, we must
know what tools are available and have access to them. Then we must know
which of the tools at our disposal is best for each situation as well
as how to use them properly and efficiently. Getting to a minimal level
of proficiency often requires access to additional resources, experience,
training, support, mentoring, a willingness to take risks, and in many
cases a new perspective or vision.
These innovative technologies are called "enabling" because
they permit us to perform tasks more easily or do things that were not
even possible a few years ago. An in-depth understanding of these enabling
capabilities usually requires the integration of multiple technologies.
Often we must seek new approaches to delivery of our programs. In this
new vision computers will be working in tandem with rather, than replacing
people.
In the future, it will not be enough to "build it and they will
come", as was dramatized in the movie Field of Dreams. But the first
step in this process is to have a dream. Then is it up to visionaries
and professionals working in teams to seek practical ways to incorporate
that dream into every aspect of our work and our lives.
In the sections that follow, I challenge you to take a peek into the
future. Accept that we have entered a new information age and that we
must be committed to seeking new types of solutions to many of our pressing
problems in health, education, and medicine. I encourage you to read and
explore the thoughts of some of the great thinkers and practitioners who
have been inspirational to me such as Nicholas Negroponte, C. Everett
Koop, Alvin Toffler, Vannevar Bush, John Naisbitt, Francis de Dombal,
Victor Strecher, James Prochaska, Everett Rogers, and Robert Karch.
A. Background
I became enthralled with the potential for computer technology because
of three experiences. First, I began to use computers as a way to make
my work easier. I realized that computers offered me an efficient solution
for repetitive tasks. Knowing that the computer made less mistakes than
I did was an important factor. I could take work that I had already completed,
edit or reformat it, and then submit it as a different product for a new
situation. I didn't have to start all over each time.
My first extended experience with the Internet in 1993 was a profound
influence that propelled me to explore ways to infuse technology more
deeply into my work and studies. At a weekend seminar, I began to realize
that if I had access to a networked computer, I had access to unlimited
resources. I could go to the best libraries in the world. I could send
an electronic message to the greatest experts on the planet. I could instantly
download programs, files, data, and information that would make my job
much easier. In exchange, I could offer information to others who might
think that what I thought is important and worthwhile.
The third experience was more subtle. While working on a project at
a local elementary school with a professor, I was struck by the fact that
the new generation of children will think of computers and the Internet
differently. They will regard the emerging technology of today in the
same way people have come to view cars, telephones, airplanes, radio,
cellular phones, electricity, satellites, and TV. My professors' five-year
old son Tony, thought that anyone should be able to see and talk to his
father in real-time, 3000 miles away once they learned to turn on a computer,
click on an icon, and look into a camera that cost only $99. The next
wave of advancements in technology will be regarded as a natural part
of their lives. Children are being raised in a vastly different world
and have much different expectations about what is possible.
It is important for us to begin to rethink the way we provide service
to others. We should seek ways to incorporate these powerful tools into
our lives and our work. We need to reach out to people in other disciplines
and learn what kinds of tools are available and how to use them. We must
ask experts from other fields to help us through the frustrating learning
times and most importantly to help inform them of the unique needs and
challenges that exist in our professions. By working together and guiding
others who are anxious to develop solutions for professionals in education,
health, and medicine we can make sure that the final products will meet
the requirements of our jobs and be of real value to those we serve.
II The concepts
A. Definitions and Terms
The following are lay definitions and terms of the words and concepts
that I will be using in this paper. In some instances I have provided
the context in which they will be used.
- Computer - many forms electronic devices such as workstations,
laptops, personal digital assistants (PDA)s, Palmtops, NetPCs, intelligent
chips, etc.
- Informatics - the application of the art and science of information
science.
- Network - computers that are linked with other computers through
telecommunications connections. The networks can be open as on the Internet
or segregated into groupings such as a local area network (LAN), wide
area network (WAN), and closed communities like intranets and extranets.
- Technology - I generally define technology as the devices or
appliances related to computers, chips, hardware, software, and peripherals.
However, it is often used in a broader context to include devices, as
well as processes, that are associated with technology or the transferal
of information or knowledge. There is a great deal of practical, technical,
and tacit knowledge associated with technology.
- Telecommunications - provides connections between computing
devices. The broad array of connections includes phone lines, fiber-optic
cable, wireless, microwave, satellite etc.
- Internet - the Internet is the "network of networks";
the interconnection of computers through telecommunication linkages.
The Internet encompasses many features such as the World Wide Web, e-mail,
and a wide variety of less familiar applications such as file transfer
protocol, electronic data transfer, and video conferencing, to name
a few.
- World Wide Web (WWW) - the "Web" uses an application
called a "browser" that permits the presentation of text,
graphics, and multimedia files in standardized format across a variety
of computing platforms.
- Electronic Mail - (e-mail) - messages that can be transmitted
electronically. Although most messages are primarily text, many different
types of files can be attached to the original message and transferred
from the sender to the receiver. Each e-mail message can be addressed
to one person or many individuals at one time.
- GII/NII/HII - the telecommunications infrastructure that allows
connections among computers throughout the world. Subsets of the overall
infrastructure are the global (GII), national (NII), and health (HII)
information infrastructure.
- Health promotion - is defined by Michael O'Donnell as, "the
art and science of helping people or groups to make lifestyle changes
that lead to optimal wellness or higher quality of life." (O'Donnell,
1995).
- Telehealth/telematics - programs, applications, services that
are delivered on or through the infrastructure. The programs are usually
health or medically oriented. They include systems programs and applications
that facilitate the distribution of information, education, telemedicine,
remote monitoring, data collection and surveillance, and various forms
of consultation and video conferencing.
- Health Promoting Technologies - refer to all systems, programs,
and applications that provide information, education, motivation, and
support behavior change or healthy environments.
III. The Need
Three startling statistics summarize the need as well as the opportunity
for the future of health promoting technologies.
- 70% of chronic disease and early death are preventable through lifestyle
changes (McGinnis, 1995). Implication: technology can have a positive
impact on these behaviors and enormous savings in human and economic
terms can be made.
- 20% success rates for health interventions in changing behavior are
considered to be effective (Karch, 1996). Implication: traditional programs
have been undereffective; new innovative approaches are warranted.
- 80% of all injuries, illnesses, and afflictions are managed through
self-care (Kemper, 1993). Implication: informed individuals can be the
best advocates for their health that will lead to significant reductions
in utilization of resources for non-serious health and medical conditions.
IV. Forces or Drivers
A. General
Several factors have had a profound influence on the massive shift in
resource allocation and the way business is being conducted. These interrelated
factors are exerting pressure for change in the technology, medical, and
health care sectors.
- Demographics - Among the significant changes that affect the
composition of the world population are aging, multiculturalism, population
shifts, and population diversity.
- Information age - Most experts have concluded that we are in
the information age where information is power.
- Cost savings - Governments are being forced to reduce healthcare
costs and deal with increased demand for services and expensive new
technological options.
- Consumerism - In many countries, there has been a dramatic
shift toward self-advocacy and consumer activism.
- Complexity - In the information age the ability to manage,
filter, and control the flow of information will be critically important
skills.
B. Technology
The pace of technology development has been astounding. There
is no way to predict exactly what the future will be like, but we should
assume that it will be radically different.
- Moore's Law - every 18 months the computing power (chips) doubles.
- Telecommunications - enormous advances have been made in areas
including bandwidth, Internet II, satellites, wireless, microwave, and
videophones that allow for moving massive amounts of data and cheaper
communication anywhere.
- Diffusion of technology - the spread of technology has been
rampant. It is being embedded in all aspects our lives and manufactured
products.
- Performance - the business principles are driving much of the
change process --> more, faster, cheaper, better; but with less resources.
C. Medicine/Health
Technology has made significant contributions to our capacity to provide
better and more effective care and treatment for mankind. There is a never-ending
desire and need for the best services that the health professions can
provide.
- Medicine - the complexity of care and management issues are
driving change (explosion of knowledge, competing demands, complexity
of technology, and management of care and records).
- Health - users and providers are searching for ways to expand
the exchange of information and new approaches for educating populations
(awareness, communication, behavior change, and compliance).
D. Sport/Physical Education
Sport and physical education share some common needs. Technology
offers many new opportunities for improvement in both fields.
- Sport - new ways of improving education, practice, and performance
(knowledge and use of sophisticated training methods).
- Physical Education - innovative ways to approach teaching,
training, practice, physical activity, and socialization (information,
training, education, motivation, and movement).
V. Models and Theories
A. General
The bulk of my work is based on three interrelated domains health, technology,
and behavioral sciences. The health promoting technologies are related
to five areas that correlate to the three domains.
- Health --> health promotion (e.g. how can we help people
to achieve optimal wellness and enhance their quality of life?).
- Technology --> programs and applications (e.g. what are
the best and most appropriate systems, programs, and applications for
health promotion?).
- Informatics --> the application of the science of information
science (e.g. how can we use the principles of information science to
design and deploy the most effective products?).
- Sociology --> diffusion of innovations and social marketing
(e.g. what steps and approaches can be used to increase the diffusion
of technology and enhance its impact?).
- Psychosocial --> customization/ personalization (tailoring)
(e.g. how can the power of the technology be employed and what methods
can be used to match the interventions with each user?).
B. Theories and Models - Health
Three models have been used in the health professions to provide services
to their clients. The approaches to treatment or service are different
for each of the models.
- Medical model - the emphasis is on treating diseases and illnesses
when symptoms are manifested.
- Public/preventative health - in most countries programs are
reactive and preemptive.
- Health promotion - the emphasis is on enhancement and optimization
(Wellness and Quality of Life).
C. Theories and Models - Health Promotion
Four popular models have been developed for health education and health
promotion programs. The models are used to explain how to achieve changes
in health behavior in target populations.
- Health Belief Model - value expectancy theory - Jans and Becker
- Theory of Reasoned Action - beliefs and behavior - Bandura
- Theory of Planned Belief - behavioral control - Fishbein
- Transtheoretical Model - Stages of Change, self-efficacy, balance
perceptions, goal setting etc. Prochaska and DiClemente
- Health technology - at present, there is no model that is appropriate
for all of the dimensions of health promoting technologies (Cassell,
1998).
D. Health Informatics Principles
There are four major concepts on which health promotion technology is
based. Each has features which can be integrated into systems and applications
to achieve maximum success.
- Information age - open access, shared data, and ubiquitous
computing windows
- Enabling - user-centric and exploit the full power of technology.
- Consumerism and empowerment - self-advocacy facilitated through
technology and networking.
- Mass customization - tailoring --> dynamic (manual or intelligent)
to the specific characteristics of each user.
VI. Measurement and Metrics
There are several ways to measure the success or effectiveness of interventions.
It is important to evaluate each program. Several commonly mentioned criterion
are listed below.
- Satisfaction - did they like it?
- Outcomes - did it make a difference?
- Interest - did it create awareness or open up new channels?
- Behavior change - did the behavior (or stages) change?
- Self-efficacy - was there a change in perceived control or
competency?
- Use patterns - what, when, how much, and why measures of the
parts of the system or program.
- Support - did the program increase the level of support? (connectedness)
- (eg. chat room, listserve etc.).
VII What's Happening
A. In the USA
The United States is considered a leader in many areas of technology.
The points below are among the most significant developments and trends.
Many of these phenomenon overlap.
- Computers - enormous developments in all areas including ease
or use, numbers, speed, multimedia capabilities etc.
- Telecommunications - great increases in capacity and options
- phone, cable, wireless, microwave, satellite etc.
- Wired Communities - many new options and paradigms such as
university campuses, businesses, Intranet, Extranet, Internet, virtual
communities etc.
- Communications - the type and popularity of electronic communications
such as e-mail, Listserves, Newsgroups, Bulletin boards.
- Approaches - significant developments in approaches are used
to reach users such as push vs. pull.
- Datamining and market segmentation - full exploitation of data
and application of data to customer markets ( eg. Firefly).
B. In South America
Significant developments are occurring throughout South American and
the Caribbean. A few of them are mentioned below.
- WHO - has made a strong statement about the value and priority
of information.
- PAHO - has major initiatives such as Informatics 2000 initiatives.
- Health Ministries - are implementing its plans through collaboration
and summits.
- Professional organizations - are developing on-line services
(eg. AMA, BMJ, CIUCFPESP, federations etc.).
- Libraries - are migrating toward full on-line access - (eg.
BIREME, NIH/NLM etc.).
- Non-profit sector - many are developing on-line services -
(eg. Red Cross, IHC, LaLeche Lingua, United Nations etc.).
- Universities - many are developing exemplary programs in training,
education, and research.
C. In Venezuela
Some of the projects in Venezuela are mentioned below.
- PanAmerican Federation of Medical Schools - Dr. Pablo Pulido.
- Virtual University - training and telemedicine.
- Informatics 2000 task force - through PAHO.
- International Development Bank - Health Task Force - Dr. Jose
Felix Oletta
- InterAmerican Consortium of universities and Training Centers of
Health Education and Health Promotion Personnel.
VIII. Technology - Approaches
Several types, approaches and concepts are featured or built into these
systems.
- Static vs. dynamic - those that remain the same vs. those that
change "on the fly".
- One-way vs. interactive - linear vs. hyperlinked and user driven.
- Self-contained vs. distributed - single workstation vs. networked
computers.
- Push vs. pull - information is provided without a request vs.
user must actively seek information.
- Dumb vs. intelligent - a static self-contained system vs. one
that learns and changes.
- Individual vs. expert - each person working alone vs. collaboration
and use of heuristics.
- Synchronous vs. asynchronous - one way communication vs. simultaneous
transmission.
- Real-time vs. store and forward - at the same moment vs. retrieved
at a later time.
Health Technology Applications
Several of the most important applications and uses for technology in
health, medicine, and education are listed below.
- Information - information can lead to better health.
- Decision support - technology can help make better decisions.
- Behavior management - intervention programs can help to guide
individuals to better health.
- Compliance, tracking, monitoring - can help reinforce and sustain
interventions.
- Surveillance - technology can help practitioners know where
the problems are and the incidence.
- Support - can help to assist users and create a healthy environment.
- Training - can be used to help dissemination of best practices.
IX. Health Technology Applications
Some of the more advanced applications for technology can be incorporated
into a variety of fields.
- Education - teacher training.
- Simulations - practice/pre-training.
- Expert systems/Artificial intelligence - assistance with advanced
decision making.
- Web-based applications - ubiquitous access to and dissemination
of information and data.
- Video conferencing - remote counseling, and face-to-face dialogues.
- Integrated multimedia/multimodal - use of many simultaneous
channels in interventions.
X. Downside/Disadvantages
Many legitimate concerns that are associated with technology have been
cited. When safeguards are not in place or systems are not designed or
maintained properly, serious problems can occur.
- Privacy and confidentiality - breaches of personal or group
ethics or standards.
- Language - sophisticated systems to handle multiple languages
are not commonplace.
- Cultural appropriateness - it is difficult to design systems
that are localized.
- "Profiteering" (unethical) - exploitation of users
for profit.
- Netfilth - pornography, bigotry, and other indecent activities.
- Harm/damage to users - bad, misleading, or inappropriate information.
- Lack of touch - the lack of personal interaction.
XII. Barriers/Problems/Issues
Several obstacles and negative aspects that are associated with the
implementation or spread of technology have been identified.
- Unrealistic expectations - considering technology as a panacea.
- Bad decisions and information - selecting the wrong system
or taking bad advice.
- Technophobia - fear or aversion to technology.
- Isolationism - desire to avoid contact with others.
- Cost and access - the gap between the have's and have-not's.
- Security - preventing unauthorized access to data and systems.
- Awareness, understanding, tacit knowledge - lack of comprehension
of what is available or possible.
- Support, training, help - lack of access to quality technical
support.
- Competing priorities - advancement of technology often is a
second tier option.
- Time - too much to do in too little time.
XIII. The Future
I believe that some of the following developments will apply in the
future.
- Data/information intensive - data will be collected routinely
and will be mined for strategically important information.
- Ubiquitous - anytime, anywhere, anyone - people will be able
to access and communicate through a variety of appliances and technology
windows that require little or no skills.
- Intelligent - systems will learn and adapt over time and use.
- Global and networked - everyone and everything will be interconnected.
- Seamless (and non-intrusive) - many sophisticated operations
will take place often without the user knowing what is going on.
- Personalized - interfaces and programs will be customized to
individuals.
- Support - systems will be used extensively for a variety of
individual and group support functions.
- Guardian angel - systems will evolve into non-intrusive, intelligent,
personalized health valets (Szoloivtz, 1994).
XIV. The End
A final thought: Although a great deal of study and advancement
has taken place, some individuals are very concerned that a unhealthy
gap will be created between those who have the resources and access to
advanced technologies and those who do not. We must make sure that we
do not create a world of have's and have-not's. We must make sure that
our planning includes ways to make all people equal Thank you for the
opportunity to present my thoughts. I think it is fitting to
end with a quote from Alvin Toffler. "The neglected fact that big
breakthroughs often come not from a single isolated technology but from
imaginative juxtapositions or combinations of several of them" (Toffler,
1980). I welcome your thoughts and comments. You can e-mail them to me
