Summary
Within the Department of Health and Human Services (HHS), a network of
agencies conducts and funds basic research and clinical evaluation of new medical
technologies. Critics say the system is not well coordinated among HHS agencies.
Ultimately, data on how a new medical product impacts health outcomes are necessary
to make judgments on the effectiveness and value of that product to patients. Little of
these data are collected in a systematic way. HHS is interested in identifying barriers
and implementing strategies to make data collection easier, more coordinated, and
consistent among the agencies. This report discusses the types of medical research
supported by HHS and gives an overview of the agencies’ missions. The report, which
will be updated, also lists options for making the process of bringing medical innovation
from the laboratory bench to the patient’s bedside more efficient and predictable.
Types of Research on Medical Technology
Basic research is conducted for the advancement of knowledge. In medicine,
research questions focus on the cause and effects of health and disease. There is no
obvious application of basic research, other than laying a foundation of knowledge for
other scientific endeavors. Findings are often published in peer-reviewed journals.
Applied research builds on the foundation to ask specific questions for a specific purpose.
Increasingly, the line between basic and applied research is blurred, as some would argue
that the overarching goal of basic research is to uncover information about targets and
processes to ultimately improve health and ameliorate disease.
Clinical trials are studies that investigate the safety and effectiveness of new drugs
or medical devices compared to a placebo or current alternatives. Clinical trials are
designated as phase I, II, III, or IV, based on the questions that the study is designed to
answer. Phase I trials initially study a new drug or device in a small group of people (e.g.,
20-80) to evaluate its safety, determine a safe dosage range for drugs, and identify side
effects. Phase II trials study the product in a larger group of people (e.g., 100-300) to see

whether it is effective and to further evaluate its safety. Phase III trials investigate the
drug or treatment in large groups of people (e.g., 1,000-3,000) to confirm its effectiveness,
monitor side effects, compare it to commonly used treatments or devices, and collect
information that will allow the drug, treatment, or device to be used safely. Phase IV
trials are usually large-scale, multicenter post-marketing studies, which are conducted
after the Food and Drug Administration (FDA) approves a new drug or device for
marketing, in order to demonstrate further evidence of effectiveness in a broader clinical
context.1
Health services research (HSR) investigates the relationship between medical
services and health outcomes experienced by a patient, and strategies to understand how
a health care delivery system can provide access to high-quality, high-value care for
various patient populations. The results of HSR studies can provide policymakers with
information to assess the impact of system changes on outcomes, quality, access to, cost,
and use of health care services across different populations.
HHS Agencies That Evaluate New Medical Products
Within the Department of Health and Human Services (HHS), a network of agencies
conducts and funds basic research2 and clinical evaluation of new medical technologies.
Critics say the system is not well coordinated along the continuum of technology transfer
from benchtop research to patient care. Current estimates suggest that it takes 10 to15
years, and $800 million to $1.7 billion in public and private investment, for a new drug
to go from the laboratory to patient care.3 HHS invests heavily in medical innovation4
all along the continuum, including (1) grants for basic research; (2) funding for clinical
trials; (3) technology assessment to support decision-making; (4) health outcome studies;
(5) programs or demonstration grants administered by states; or (6) coverage in public
insurance systems (e.g., Medicare and Medicaid). In supporting these efforts, Congress
may wish to consider the data needs of each agency that ultimately impact when and how
a medical product will become available for patient care.
National Institutes of Health (NIH). The goal of NIH research is to acquire new
knowledge to help prevent, detect, diagnose, and treat disease and disability, from the
rarest genetic disorder to common conditions. NIH conducts research in its own
laboratories, supports the research of nonfederal scientists in universities, medical
schools, hospitals, and research institutions throughout the country and abroad, helps to
train research investigators, and fosters communication of medical and health sciences

information.5 The NIH budget has doubled in the past five years to $27 billion. The NIH
Roadmap Initiative, put forth by Director Elias A. Zerhouni, and developed with input
from more than 300 nationally recognized leaders in academia, industry, government, and
the public, is a plan to prioritize and speed the transfer of research into clinical practice.6
Food and Drug Administration (FDA). The FDA is responsible for protecting
the public health by assuring the safety and efficacy of drugs, biological products, and
medical devices. The agency helps to ensure that the public gets accurate, science-based
information needed to use medicines and diagnostics effectively.7 FDA reviews drugs and
devices, but it does not review entire treatments or procedures. In the face of declining
numbers of product submissions, the agency recently published its Critical Path Initiative,
which aims to identify and prioritize the most pressing problems in product development
and areas and calls for a collaboration of stakeholders to develop targeted solutions.8
FDA recently sought comment on scientific and technical hurdles that cause delays in the
product development process (69 Federal Register 21839 [April 22, 2004]).
Centers for Medicare and Medicaid Services (CMS). CMS’s mission is to
ensure health care for beneficiaries, with the goals of protecting and improving
beneficiary health and satisfaction, fostering appropriate and predictable payments and
high-quality care, promoting understanding of CMS programs among beneficiaries, the
health care community, and the public, and promoting the fiscal integrity of CMS
programs.9 Medical innovation does not reach patients unless someone pays for it. For
persons covered by the program (the elderly and certain disabled individuals), Medicare
plays a large role in determining what services will be covered for beneficiaries.10 In
2002, Medicare expenditures for new drugs and devices were approximately $4 billion
to $6 billion (69 Federal Register 29544 [May 24, 2004]). Despite efforts beginning in
1989, Medicare has not been able to promulgate criteria by which coverage decisions are
made.11 CMS policy, however, has been working toward making the process more open
to the public, so that coverage decisions about new technologies can be vetted.

Agency for Healthcare Research and Quality (AHRQ). AHRQ is the health
services research arm of HHS, complementing the biomedical research mission of its
sister agency, the NIH. Research at AHRQ specializes in major areas of health care, such
as quality improvement and patient safety, outcomes and effectiveness of care, clinical
practice and technology assessment, health care organization and delivery systems,
primary care (including preventive services), health care costs and sources of payment.

ARHQ is a major source of funding and technical assistance for health services research
and training at leading U.S. universities and other institutions.12
Centers for Disease Control and Prevention (CDC). The goal of CDC is to
promote health and quality of life by preventing and controlling disease, injury, and
disability. The CDC seeks to accomplish its mission by working with partners to monitor
health, to detect and investigate health problems, to conduct research to enhance
prevention, to develop and advocate sound public health policies, to implement
prevention strategies, to promote healthy behaviors, to foster safe and healthful
environments, and to provide leadership and training.13 This role supports new
technology development by tracking disease and statistics, and monitoring the health of
the population.
Health Resources and Services Administration (HRSA). HRSA’s mission
is to improve and expand access to quality health care for all Americans, and to ensure
the availability of quality health care to low-income, uninsured, isolated, vulnerable and
special-needs populations.14 HRSA helps to support technology development by ensuring
that medical innovation addresses the health needs of vulnerable populations, and that
appropriate populations are included in clinical research.
Strategies for Evaluating Medical Innovation
Ultimately, data on how a new medical product impacts health outcomes are
necessary to make judgments on the effectiveness and value of that product for patients.
In times of constrained resources for healthcare, some assert that HHS needs to assess the
effectiveness and value of new technologies at each stage of research activity through
more effective collaboration of federal assessment efforts and integration with private
efforts. HHS agencies, they say, will need a better means of “handing the baton” among
agencies to evaluate different snapshots of the process to create a panoramic view of
effectiveness and value, and to put the nation’s investment in research into practice
without stifling innovation. Advocates urge that funding initiatives include downstream
investments in health services research as a natural outgrowth of the substantial
investment in basic research.
Legislation may have impact across the spectrum of medical technology transfer,
rather than just on isolated elements. For example, the Food and Drug Administration
Modernization Act of 1997 (FDAMA) made it easier and quicker for medical products
to get FDA approval. The Act included language in section 505(d) to clarify that “data
from one adequate and well-controlled clinical investigation15 and confirmatory evidence”
could constitute substantial evidence of effectiveness if FDA so found, where previously

evidence from several trials were typically required. In addition, the Act encouraged the
agency to develop surrogate endpoints as predictors of a drug’s therapeutic effect.16
These actions to bring medical products to market quicker seem at odds with
requirements of Medicare, where FDA approval is often necessary, but not always
sufficient, for the program to pay for a service. In contrast to FDA’s regulations, the
statutory standard for a covered item under Medicare as defined in Title XVIII of the
Social Security Act, Section 1862(a)(1)(A) is that the item be reasonable and necessary
for the diagnosis or treatment of illness or injury or to improve the functioning of a
malformed body member.17 Medicare has interpreted the statute by looking for evidence
that the service is medically necessary and effective, and that the service is not
experimental. Medicare’s guidelines for assessing effectiveness18 rely on outcomes data.

In the past, FDA and CMS have been interested in coordinating their assessments,
but cultural, political, regulatory, and/or statutory differences in their authorities may
prevent them from sharing data. Characterization of the barriers and the extent to which
they may impede more efficient technology assessment was considered in a 2004 HHS
meeting on medical innovation.19 In January 2005, HHS released a report detailing five
recommendations: (1) enter into new or expanded Memoranda of Understanding with
appropriate non-HHS federal agencies to promote more rapid and efficient technology
transfer; (2) streamline HHS involvement in medical technology transfer; (3) improve
collaborations between FDA and CMS; (4) support standardized formats for electronic
clinical trials data; and (5) initiate a training program in technology development and
transfer for HHS personnel, scientists, and engineers.20
Several additional ideas have been suggested for improving coordination between
agencies. Proponents envision these ideas as complementing each other without being
redundant, and facilitating interagency coordination rather than stifling innovation.
! The NIH, FDA, and HRSA could work together to include vulnerable
populations (e.g., children, the elderly, minorities, or patients with
cognitive impairment) in clinical trials. This action would help to assure
16 Surrogate endpoints are typically laboratory signs or physical findings that are plausibly
correlated with a health outcome. See 57 Federal Register 58942 (Dec. 11, 1992). Use of
surrogate endpoints reduce the time a drug needs to be studied. The problem with surrogate
endpoints is that often they are found not to be highly predictive of a health benefit. As a result,
other programs — such as Medicare — still rely on actual health outcomes as measured
endpoints before “approving” an intervention under their program.
17 Medicare does cover certain preventive services as a matter of exception under Section
1861(s)(10) (i.e., for pneumonia, influenza, and hepatitis B vaccines), and certain screening
services that are defined in the statute.

safety and effectiveness in the same populations that CMS and/or AHRQ
will need to evaluate for determining coverage or social value of service.
! The NIH, CDC, FDA, and CMS could establish a working group to
determine relevant data elements for measuring, evaluating and tracking
the course of disease (or health) and the effectiveness of intervention.
Following approval of a product for marketing and/or coverage, FDA
and CMS could make, as a condition of approval or payment,
requirements for reporting information to CDC and/or FDA for post-
market surveillance.
! The FDA and CMS could work together with researchers, manufacturers,
and sponsors who are planning clinical studies to develop protocols that
would provide for the collection of the relevant outcomes measures the
agencies would need to demonstrate safety and effectiveness for FDA,
and medical necessity for CMS.21 After the study was completed, the
agencies would separately evaluate if the sponsor met the respective
standards and would define the circumstances of product approval and/or
coverage applications.
! If CMS requires data beyond those that are necessary for FDA approval,
FDA and CMS could work to determine appropriate post-market
requirements. These requirements could consider data that AHRQ may
use to support an evidence report or technology assessment.22 Under a
discretionary provision, FDA may require post-market surveillance for
products if deemed necessary to protect the public health.23 CMS
expressed recent interest in working with NIH to develop a registry for
post-market surveillance for implantable cardioverter defibrillators.24
! CMS and AHRQ could work with the sponsor of the technology to
define flexible criteria or thresholds for establishing acceptable
effectiveness or value of a new medical product. These can be
technology-, service-, or disease-specific. Once the threshold of the
medically reasonable and necessary standard is met, further studies could
address value.
