Statement of
Carolyn M. Clancy, M.D.
Director
Agency for Healthcare Research and Quality
U.S. Department of Health and Human Services
Mr. Chairman and Members of the
Subcommittee, I am Dr. Carolyn Clancy, the Director of the Agency for
Healthcare Research and Quality (AHRQ), a component of the Department of
Health and Human Services (HHS). Today I have the privilege of
representing the Department and want to thank you for the opportunity to
participate in this discussion of the role of telemedicine in improving
the health care of America’s veterans.
The Department of Health and Human Services (HHS) has had a
long-standing commitment to understanding and advancing the effective
use of health information technologies, including telemedicine, to
improve the health of all Americans. As we use the term, telemedicine is
the use of telecommunications technology for medical, diagnostic,
monitoring, and therapeutic purposes when distance and/or time separates
the participants. At the outset, we need to acknowledge that a great
deal is not known about telemedicine. But we share a common interest
with our colleagues at the Department of Veterans Affairs in attempting
to identify best practices and promising interventions. So we are
delighted to participate in this hearing to provide a brief overview of
our Department’s telemedicine activities and share our preliminary
findings and experience.
Setting the Context
I would like to begin by offering seven observations regarding
telemedicine.
First, the use of telemedicine in the private sector is still relatively
small but growing.
Second, there is evidence that the technology can work, and can be used
beneficially from a clinical and economic standpoint. However, I must
add a note of caution. While there are many promising initiatives
underway, there are few mature telemedicine programs and few good
scientific evaluations. There are, nonetheless, lessons learned that may
prove useful to the VA. However, there is an obvious need to work
collaboratively to identify best practices.
Third, it is also difficult to assess the appropriateness, effectiveness
or cost effectiveness of telemedicine in the abstract. It is best to
focus on the service that telemedicine is being used to provide (such as
the provision of radiology services or specific home health services),
how it is being used for that purpose, and in what types of settings it
is being used. Telemedicine may be effective in one specialty but not in
another.
Fourth, as with all technologies, telemedicine is merely a means to an
end. Too many evaluations assess aspects of the technology itself. What
should be assessed is whether the telemedicine service leads to better
patient care and at what cost. Specific applications should always be
assessed in terms of how they further our common goal to provide access
to clinically effective, safe, and timely care to our patients
efficiently.
Fifth, the array of obstacles to adoption and use of telemedicine
services in the private sector is different in some ways from those
confronted by the Department of Veterans Affairs’ relatively “closed”
health care system. For example, financial incentives or legal issues
such as antitrust, malpractice, and cross-state licensure are more
significant issues outside the VA. As a result, some of our Department’s
work related to use and adoption in the private sector may not always be
directly transferable to the context in which the VA operates.
Sixth, with certain exceptions, such as tele-radiology, clinicians and
system managers have been slow to adopt telemedicine. It is increasingly
clear that a variety of factors need to be in place before clinicians
believe that the value gained exceeds the effort required to implement
new technology. User operability issues are complex and are important to
the adoption of effective telemedicine services. Similarly, the
education of users is a critical issue.
Finally, under Secretary Michael Leavitt’s leadership, HHS is giving the
highest priority to fulfilling the President’s commitment to promote
widespread adoption of interoperable electronic health records. This
movement could be a significant enabler for the adoption of telemedicine
in the future. The prospect of direct, immediate, interactive linkage
between telemedicine applications and a patient’s electronic health
record, across settings of care, has the potential to alter the calculus
for their evaluation of specific telemedicine applications and ease
clinician concerns regarding the effort required to use the technology.
HHS Telemedicine Activities
HHS agencies have supported telemedicine research or demonstration
projects for over three decades but the level of activity increased
significantly in the last decade. As more agencies became interested in
telemedicine, HHS took two steps to increase coordination within the
Department and the rest of the Federal Government. The first action, in
1995, was the establishment of a Joint Working Group on Telemedicine to
enhance coordination within the Department and other Federal agencies to
more systematically identify barriers to telemedicine deployment.
In 1998 the Office for the Advancement of Telehealth (OAT) was
established to serve as a focal point for coordinating telehealth
programs within the Health Resources and Services Administration (HRSA)
and to work with other Federal, State, and private agencies to advance
the field. In 2002, Congress formally established the Office in statute.
The overall focus of HHS’ telemedicine activities has been to expand
access to quality health care through the use of telecommunications and
information technologies. It is not solely focused on the technology.
Grant Programs
Since 1988, the Department has awarded at a minimum more than $250
million in telemedicine projects in every state of the Nation, with over
400 communities benefiting from these grants. In 2005, OAT will
administer approximately 150 telehealth projects; this number includes
15 new competitive awards in FY05 for $3.9 million. In addition, HRSA,
at the direction of Congress in P.L. 108-447, will make approximately 77
awards for a total of $31 million for telehealth projects. These
projects include classic telemedicine programs for the delivery of
health care, electronic health record/information system development and
deployment (including telepharmacy, e-prescribing), and distance
education. The majority of these grants serve rural communities.
The data on home care is quite promising. Although the studies are
small, experience indicates that major savings and improvements in
quality of care can be achieved for chronic care patients. By more
closely monitoring these patients in their home, they were able to
prevent acute exacerbations of chronic disease. For example, one grantee
study showed that expenses can be cut in half through the use of
telemedicine for a cohort of chronically ill patients with congestive
heart failure and diabetes, compared to national statistics for a
similar population. Similar findings have been shown in studies by
Kaiser Permanente and the VA.
Promoting Access in Rural Areas
While there are few programs from which high quality data are available,
a baseline analysis by HRSA’s Office of Advancement of Telehealth of 19
rural telemedicine program grantees showed that many communities would
have no access to adult psychiatric services, pediatric psychiatric
services, dermatologist services, neurological services, specialized
wound care consultation services, and genetic counseling, if
telemedicine services had not been provided by these grantees.
A baseline study of eight rural telemedicine grantees with tele-home
care programs found significant potential productivity gains were found
for nurses by reducing travel time. During the baseline period
(September 2002-August 2003), approximately 2,100 nurse hours were saved
through reduced travel for trips that otherwise would have been done in
person. These hours translate into approximately $80,000 of salary and
travel costs saved during the baseline period. In reality, rather than
simply reducing nursing costs, the nurses who spent less time driving
were able to care for more patients – stretching the short supply of
nurses to improve access for more patients. Homecare agencies that spend
less on gas can spend more on other supplies or services.
The Indian Health Service
The Indian Health Service (IHS) is the closest HHS parallel to the
context in which the VA operates. IHS and Tribal facilities report
experience with over thirty different types of telemedicine clinical
service. Similar to national U.S. experience, tele-radiology, tele-retinal
screening, tele-dermatology, tele-mental health, and tele-cardiology are
leading clinical telemedicine applications in Indian health.
Opportunities for expanded service delivery, however, are under
development. These opportunities include new clinical telemedicine
applications as well as project development for cost-effective and
quality-focused Virtual Centers of Excellence
Many different types of telemedicine have been successfully used by the
IHS and Tribal hospitals and clinics. Such telemedicine services have
helped address a diverse array of clinical needs, and highlight evolving
opportunities for both evidence-based and community-based chronic
disease management. For example, at 30 IHS and Tribal facilities,
patients with diabetes receive remote diagnosis and management of
diabetic eye disease via the IHS-Joslin Vision Network. In Alaska, 800
to 1000 tele-consultations are performed each month via the broadband
Alaska Federal Health Care Access Network. Many children with ear
problems receive pre and post-operative care from ENT surgeons at the
Alaska Native Medical Center in Anchorage via tele-consultation on this
network. In southern Arizona, patients with heart failure have access to
cardiologist case management services from the Native American
Cardiology Program via home telehealth. Tele-cardiology care also
supports interpretation of electrocardiograms and echocardiograms
performed at rural Indian health facilities.
On the Navajo Nation, women’s health services include rapid mammography
interpretations through telemedicine links from Navajo Area IHS and
Tribal facilities to a specialty Breast Center in Tucson. Similar tele-mammography
services will soon be available from a mobile women’s health project set
to begin in North Dakota and South Dakota.
Tele-mental health service is a growing part of many rural Indian health
programs. One program offers confidential and parent-consented tele-mental
service to high school students in a school-based clinic. Finally,
community outreach via telemedicine extends medication refill service
and creative health promotion /nutrition education for patients and
families on the Western Navajo Nation.
Non-Clinical Uses
Innovation is also underway for non-clinical telehealth projects. These
projects use videoconferencing technology for distance learning, program
planning, and administrative meetings. Many Indian health care
facilities currently participate in such activities. New approaches to
learning include Virtual Grand Rounds, distance education via the
Pathways into Health project for American Indian and Alaska Native
students seeking Medical Technologist and other health professional
degrees, and multi-media continuing education coursework in a variety of
clinical disciplines.
Telemedicine for many IHS and Tribal facilities is made possible by
partnerships with state telemedicine networks and regional
telecommunications infrastructures. Noteworthy examples of such
partnerships include: the Alaska Federal Health Care Access Network, the
Navajo Area and Phoenix Area Telehealth Networks; and the Arizona
Telemedicine Program. The Alaska Federal Health Care Access Network
extends telemedicine services to 200 IHS and Tribal sites in the state
of Alaska. The Arizona Telemedicine Program facilitates diverse
telemedicine activities at numerous IHS/Tribal facilities in the
Southwest United States.
Building and Understanding the Evidence Base for Telemedicine
At the request of the Centers for Medicare and Medicaid Services (CMS),
my agency, AHRQ, developed an evidence report in 2001 that reviewed the
available evidence on the effectiveness of telemedicine interventions
for the Medicare population. The report concluded that the use of
telemedicine is small but growing. Active programs demonstrate that the
technology can work, and their growing number indicates that
telemedicine can be used beneficially from both clinical and economic
standpoints. The longevity of these programs, however, is not clear, and
many may fail to survive beyond initial funding or enthusiasm.
The report went on to state that the evidence for the efficacy of
telemedicine technology is less clear. The problem is not that studies
have strong evidence against efficacy, but rather that their
methodologies preclude definitive statements. Many of them have small
sample sizes that decrease the statistical power of the findings, and
the settings of others may not be equivalent to real life clinical
settings.
2005 Update of the Evidence Report
In 2004, AHRQ began an update of the 2001 evidence report on
telemedicine services for the Medicare population and convened a
workshop that provided additional input from leaders in the field
regarding pressing issues in telemedicine. The report is now undergoing
peer review to ensure its accuracy. We expect a final report next month
and we will provide copies to the Committee as soon as it is available.
The report focuses on what types of telemedicine services are more
strongly supported by scientific evidence and for which settings. It
identifies health care services that could be provided using
telemedicine and describes existing programs in three categories of
telemedicine:
• store-and-forward;
• home-based; and
• office- and hospital-based services.
The bottom line is that the evidence base for telemedicine is still
incomplete but improving.
I should note that we recognize that policymakers and system
administrators often do not have the luxury of waiting until an
intervention is proven effective beyond a shadow of a doubt. For those
who need to make decisions in the absence of perfect information, AHRQ
will work with them to better understand and interpret existing
evidence. At the same time, it is clear that a major impediment to
public and private sector reimbursement has been the absence of more
reliable evidence on the effectiveness of specific telemedicine
approaches. We all need to work together to try to build that evidence
base more quickly using innovative research methodologies.
For example, given the growing use of electronic health records,
selective data could be extracted on patients with telemedicine
interventions to assess them longitudinally. Such studies will be most
feasible in large integrated delivery networks with advanced electronic
health record systems such as the Veterans Administration and private
sector plans with similar capabilities.
Cutting Edge Research
I also wanted to mention two cutting edge research projects that may be
of interest to the Subcommittee. Intuitively, it makes sense to support
further research into telehealth opportunities for the “visual”
specialties that require more than voice or text communication to be
most effective. A project funded by the National Library of Medicine (NLM)
of the National Institutes of Health that is taking place at the
University of North Carolina, Chapel Hill, is developing and testing 3D
telepresence technologies that come close to supporting the illusion of
being at a remote location. This experience will allow remote
consultations to benefit from the added information gained from a
three-dimensional environment. Consultations in such diverse areas as
emergency medicine, dermatology and surgical consultations will utilize
this important breakthrough.
The second exciting and innovative project, funded by AHRQ, utilizes a
combination of telemedicine, cutting edge cancer therapy, and clinical
decision support and is pioneered by Dr. Karen Fox at the University of
Tennessee Health Science Center in Memphis. The Technology Exchange for
Cancer Health Network, or TECH-Net, provides a systematic cancer care
program for patients located in rural communities surrounding Memphis.
Patients are seen at the University, where initial diagnostic and
therapeutic interventions take place. The majority of care is then
provided in a patient’s home community by a team comprised of the
patient’s primary care physician supported by University oncology and
hematology specialists. These critical specialists communicate via
clinical decision support tools and a dedicated telehealth network.
Skilled Nursing Facilities
Finally, there is another report currently under development by the
Department in response to Section 418 of the Medicare Modernization Act.
The statute required an evaluation regarding the possibility of
including skilled nursing facilities (SNFs) as a Medicare telehealth
originating site for purposes of Medicare reimbursement. The statute
required an evaluation and a report to Congress that includes
recommendations on “mechanisms to ensure that permitting a skilled
nursing facility to serve as an originating site for the use of
telehealth services or any other service delivered via a
telecommunications system does not serve as a substitute for in-person
visits furnished by a physician, or for in-person visits furnished by a
physician assistant, nurse practitioner or clinical nurse specialist, as
is otherwise required by the Secretary.” Because the findings regarding
the use of this technology within nursing home facilities may be of
interest to the Subcommittee, we will provide you with copies as soon as
it is ready for release.
Indian Health Service – Veterans Health Administration Collaboration
As I noted earlier, the context in which the Indian Health Services
operates is the closest to that of the VA system. I am delighted to
report that there is an evolving collaboration between the IHS and the
Veterans Health Administration (VHA) telemedicine programs that
exemplifies the benefit of inter-agency information exchange and
sharing. A Memorandum of Understanding between the IHS and the VHA has
enabled telemedicine program coordinators from both Departments to
identify key areas for cooperation and possible shared resource
development. IHS and Tribal participation in the 2005 VHA Care
Coordination and Telehealth Forum underscores the commitment of both
agencies to facilitate regional and local partnerships that will
optimize resources and improve care for American Indian and Alaska
Native veterans. In partnership with conference organizers and
interested VHA employees, eighteen IHS and Tribal attendees at the April
2005 Forum developed a strategic framework for ongoing telemedicine
collaboration. This framework highlights standards-based approaches to
telemedicine service delivery that will facilitate local IHS-VHA
information sharing, secure operational capacity development, and
collaborative clinical service outreach for American Indian and Alaska
Native veterans.
The VHA has provided pioneering commitment for improved service delivery
via home telehealth. This commitment demonstrates the emerging ability
of clinicians and caregivers to reach patients and families at the point
of care. Home telehealth, delivered in a care coordination model, offers
new opportunity for enhanced access and health care system value. VHA
leadership in home telehealth and care coordination establishes a
benchmark by which IHS and other health care organizations may integrate
the patient’s home into the health care delivery network.
Private, confidential telemedicine service to American Indian veterans
in rural communities is not only possible – it is already occurring. A
unique partnership in South Dakota between the Rosebud Sioux Tribal
Veterans Program, the Rosebud IHS Indian Hospital, the Hot Springs
Veterans Affairs Medical Center, the Denver VA Medical Center, and the
Center for Native American TeleHealth and TeleEducation at the
University of Colorado Health Sciences Center provides weekly tele-mental
health treatment and counseling services for Northern Plains American
Indian veterans struggling with post-traumatic stress disorder. This
partnership evidences the capability of multi-system collaborations to
provide culturally sensitive psychiatric care to rural, isolated
communities. It has become a model for additional tele-mental health
projects currently underway or under development in other American
Indian communities in Montana.
Conclusion
Telemedicine has long been viewed as a promising tool for enhanced
access to health care services, improved patient safety, and timely
medical decision-making. Telemedicine may also enable more effective
care management for patients with chronic medical conditions. The
barriers to access that telemedicine can overcome -- geographic
isolation, functional isolation, economic barriers, a scarcity of health
professionals, or a combination of these factors – are clear.
Widespread adoption of individual telemedicine applications in the
private sector will continue to grow slowly, however, unless creative
ways are found to speed the development of solid, scientifically
generalizable findings of their effectiveness. In addition a number of
legal issues, including cross-state licensure and antitrust concerns,
must be resolved. By moving down that path, the understandable
reluctance of payers to reimburse telemedicine applications
appropriately will begin to be overcome.
As the Indian Health Service example demonstrates, our two Departments
have demonstrated an ability to work collaboratively in ways that
benefits the populations we directly serve. The use of telemedicine
applications in public programs will increase as we continue to work
together to address the common barriers to broader telemedicine use,
such as the wariness of clinicians and system managers to embrace
telemedicine applications, build the evidence base for effectiveness,
and identify best practices.
Mr. Chairman, this concludes my prepared statement. I would be delighted
to answer any questions that you or the Members of the Subcommittee may
have.
