Perspective:
Promoting The Dissemination Of Decision Aids: An Odyssey In A Dysfunctional Health Care Financing System
What stands in the way
of more widespread adoption of
useful information tools as patients choose
among treatment options?
By John Billings
ABSTRACT:
The usefulness of patient decision aids (PtDAs) is well
documented, yet they are not in widespread use. Barriers include assuring
balance and fairness (auspices matter), the cost of producing and maintaining
them, and getting them into the hands of patients at the right time. The Foundation
for Informed Medical Decision Making and its for-profit partner, Health Dialog,
have developed a creative business model that helps overcome these barriers
and has greatly expanded the reach of decision aids.
Virtually all major medical
decisions involve some amount of weighing of benefits and risks. For many
of these decisions, reasonable people might disagree about the importance
or value of the benefits and about the seriousness or degree of the risks.
And, in many cases, choices must be made for which the quality of evidence
about the options is weak, which introduces another layer into the decision-making
process on which people can be expected to differ widely: how to
make a choice in the face of uncertainty.
As detailed elsewhere in this collection of papers, there
has been increasing interest in decision aids to help patients make choices
in these situations, together with their physicians.1 Effective
patient decision aids (PtDAs) typically help frame the issues involved in
a treatment or screening decision, provide patients with the available evidence
base on the options and associated outcomes specific to their circumstances,
and help elicit and clarify patients’ values and preferences related
to these choices.
The usefulness of PtDAs and this “shared decision-making” process
is well documented: Patients who participate (1) are more knowledgeable about
treatment options and their benefits/risks, (2) make decisions that are more
consistent with their own attitudes toward these benefits/risks, (3) have
more-informed discourse with their physicians, (4) choose options
that are consistent with available scientific evidence, and (5) generally
make choices that are less costly (opting for less surgery than their more
aggressive physicians would choose).2
So what’s holding us back? Why not develop and make
available to patients and their physicians decision aids on the broad range
of medical decisions on which individuals might differ about benefits and
risks or for which the evidence on outcomes is not definitive? That was certainly
the perspective of the founders of the Foundation for Informed Medical Decision
Making, established in 1989 to produce and disseminate decision aids (initially
in the form of interactive video programs) for an anticipated library of sixty
or more topics.3 But reality does bite,
and the foundation’s experience in attempting to achieve these goals
is instructive about the barriers that will likely appear as the need to improve
decision quality becomes more paramount and as a complex range of issues emerges
about auspices, conflicting interests, and the role of government and private
interests in health care.
Reality no. 1: auspices
matter.
The foundation was established as a not-for-profit entity based on the fundamental
principle that in the case of decision aids, auspices matter. The manner in
which information is framed and presented can have an important impact on
patient choice, and decision aids can by inadvertence (or intent) steer patients
toward or away from a particular course of treatment or diagnostic procedure.
Of course, in many cases, patients can judge for themselves
whether information appears to be biased or is presented in a biased manner.
But there is a large body of literature demonstrating that how a decision
is framed can influence choice.4 The
issue is not the accuracy of the data but, rather, how they are presented;
these effects are often not apparent to patients. For example, patients’ preferences
have been shown to change depending on whether outcomes are described as the
chances of living or the risks of dying. In one study, 44 percent chose a
specific course of therapy when risks were presented as the chances of dying,
but only 18 percent did so when outcomes were expressed as the chances of
living.5 Other factors that
have been shown to influence choices include the amount of data; the vividness
of the presentation (real versus abstract patients); whether outcomes are
expressed as numbers, graphs, or narratives; whether harms are presented as
absolute risks or relative risks; and the use of lay language versus medical
terminology.6
Because these effects are subtle and generally not apparent
to patients, auspices (who paid for and produced the decision aid) can become
critical; this raises serious questions about the need for disclosure about
sources of funding and some process or mechanism to ensure that decision aids
are balanced and fair. Annette O’Connor and colleagues suggest the need
for some accreditation body for decision aids.7 In
1989, when the foundation was established, such ideas were not even on the
radar screen. The foundation’s approach was to opt for not-for-profit
status, to initially restrict sources of funding for development of its decision
aids to philanthropic sources, and to develop its decision aids by contracting
with scientific experts who were free of conflicts (receiving no drug or device
company money, for example). But this approach had its consequences:
see Reality no. 2.
Reality no. 2: decision
aids cost real money.
While the costs of decision aids are trivial in the context of overall medical
care spending, they can be costly to produce and maintain, regardless of the
medium used. At the core of any decision aid is a complete assessment and summary
of available evidence about benefits and risks of outcomes and possible side
effects. Depending on the complexity of the issues, the extent and quality
of the research base, and the prior existence of a systematic review of the
evidence, such a assessment can be costly. When the foundation was established,
Patient Outcome Research Teams (PORTs) were beginning their short-lived existence,
with funding from the Agency for Healthcare Research and Quality (AHRQ, then
known as AHCPR). These multidisciplinary teams were awarded $1
million annual grants to assemble, assess, and disseminate available scientific
evidence for specific medical problems, and the foundation expected them to
be an important source of content for the its library of decision aids. Of
course, Congress axed the PORTs in 1995, largely as the result of strong lobbying
by orthopedic and ophthalmic surgeons who were not happy with some of their
findings.8 This meant that the foundation
would be required to support its own scientific teams to develop the content
for any decision aids.
But there are other costs as well. For a PtDA to be most
useful, it is also critical to understand the symptoms and outcomes patients
care about most and the risks that are of greatest concern. For example, in
their groundbreaking work examining benign prostatic hypertrophy, John Wennberg
and colleagues found that while doctors tended to focus on urine flow rates
and acute retention, patients cared more about how much the symptoms affected
their lives and the risks associated with surgery such as retrograde ejaculation.9 Medical “experts” can
provide only part of the needed information; talking to patients in the development
process is critical, and the patient focus groups or surveys necessary to
provide this information add more expense. Also, given the rapid pace of medical
research and development (R&D), it is critical to update the evidence
base regularly to incorporate new findings. More expense—and expense
that will be ongoing.
Where should the money come from to develop decision aids?
The pharmaceutical industry is out for obvious reasons, and government is
conflicted (it is a major purchaser with strong interest in cost control);
besides, government has too often proved to be an unreliable partner subject
to political interests (as the PORT situation exemplifies). Not surprisingly,
the foundation turned to philanthropy for initial support. However, these
funders are generally interested in a one-time award that produces a tire-kickable
product that can be shown to the board and that fits in with their program
areas of interest. Sixty programs and support for continual updates are a
big lift, even for the most well-endowed foundation. Moreover, foundations
typically view themselves as the venture capital of the not-for-profit world—ongoing,
recurring expenses after the demonstration is over are somebody else’s
problem. Another reality.
Reality no. 3: a
creative business model will be required. There
is one more problem: There are no obvious champions in the health system for
getting decision aids into the hands of patients.
Perhaps right-thinking clinicians or provider organizations
interested in having their patients make good decisions could include these
expenses as one of the costs of medical practice. Unless, of course, one choice
means revenue (admit the patient and do the surgery) and another means less
revenue (watchful waiting)—even the most patient-centric physician or
hospital might begin to have reservations about a decision aid (it’s
likely to confuse the patient, or it’s too long, and so on). Besides,
as O’Connor and colleagues note, there are often serious logistical
problems in getting decision aids to patients “just in time” that
may require redesign of the clinical process to accommodate use of decision
aids in everyday practice.10
Indeed, this was the experience of the foundation in its
first years as it attempted to market its interactive video decision aid programs
to large group practices and staff-model health maintenance organizations
(HMOs). While the programs had proved enormously “successful” in
experimental mode in several practice sites (with strong patient satisfaction
and reductions in rates of surgery), the market did not respond.11 Part
of the problem related to the media format (interactive video disk requiring
special equipment and space for viewing), but even in partnership with Sony
Medical (1992–94), the costs of developing and distributing the programs
far exceeded the revenues from the limited number of users.
After numerous false starts with various potential partners,
in 1997 the foundation entered into a new commercial arrangement with Health
Dialog, a privately held, for-profit venture founded by George Bennett and
Chris McKown that offers health coaching (nurse call service), decision support,
and chronic disease management services to health plans, employers, and provider
organizations. In return for exclusive marketing rights to the foundation’s
decision-support programs (now predominantly in linear videotape format),
Health Dialog pays royalties to the foundation based on its gross revenues.
The foundation develops and maintains editorial control of the content for
the programs, which are produced and distributed by Health Dialog.
In the current fiscal year, the royalties from Health
Dialog are expected to reach $6 million, enabling the foundation to expand
its library of programs to twenty-one by the end of 2004, support a cadre
of fourteen academically based medical editors (to develop content for decision
aids and assure that it remains up-to-date with research developments), and
to fund a small portfolio of research related to decision aids (studying issues
such as framing effects and evaluating the impact of decision aids on patients’ decision
making).
Health Dialog’s success in the marketplace has greatly
expanded the reach of decision aids (with more than 20,000 video programs
distributed to patients and their families in the past year), and this creative
business model has gone a long way toward addressing the need for sizable,
ongoing financing (Reality no. 2). However, potential concerns remain. For
example, auspices matter (Reality no. 1). The foundation takes no funding
from makers of drugs or devices. An independent board, strict rules about
conflict of interest, and careful procedures to ensure balance and fairness
in the development of program content provide some reassurances and are important
steps that have been taken to insulate the foundation from threats to its
neutrality. Nonetheless, although the foundation continues to receive some
support from philanthropy, the overwhelming majority of its revenues comes
from its royalty arrangement with Health Dialog. Health Dialog has fully embraced
the importance of and need for balance and fairness (hence its relationship
with the foundation) and has supported development of numerous programs that
are economically neutral to plans (for example, breast cancer treatment decision
aids) or even potentially cost-inducing (for example, breast reconstruction
after mastectomy or treatment of benign uterine conditions). However, in the
cynical health care marketplace, the appearance of potential conflict is obvious
when major clients include health plans (which most consumers perceive to
have strong incentives to reduce spending).
Another limitation of the current business model from
the perspective of promoting decision support is the insurance plan–centric
nature of Health Dialog’s business to date. Although Health
Dialog has marketed assiduously to provider organizations, its largest contracts
remain with health plans. Provider organizations still aren’t buying
in large numbers. Although in some markets these plans have a sizable market
share (and a more direct relationship with local clinicians), entry through
a health plan can place Health Dialog at arm’s length from physicians,
despite its best efforts to engage them. As noted by O’Connor and colleagues,
there are distinct advantages to embedding decision support into routine medical
practice, especially at the primary care level, where physician incentives
on choice of treatments are generally neutral. For its health plan clients,
Health Dialog is largely dependent on its nurse call line/coaching service
to identify patients in need of decision support.
Health Dialog also has an innovative claims data–mining
capacity that can be used to identify patients that may be facing medical
decisions (for example, patients with back pain who have had magnetic resonance
imaging, or MRI), but in many cases, this information comes too late
or too far along in the decision-making process for patients. Timely identification
of patients in need of decision support can be done in a provider setting
most efficiently and effectively, but given the current dysfunctional health
care market, direct provider involvement remains a challenge that Health Dialog
struggles to adapt its product to address.
The future for decision
aids and shared decision making.
O’Connor
and colleagues have proposed demonstrations for various models of decision
support to help establish the feasibility of more widespread implementation
of decision aids. James Weinstein and colleagues have suggested that the Centers
for Medicare and Medicaid Services (CMS) redesign the fee-for-service (FFS)
reimbursement system to reward providers who implement shared decision making
in accordance with the authority granted in Section 646 of the Medicare Prescription
Drug, Improvement, and Modernization Act (MMA) of 2003. Others have also suggested
increased reimbursement for physicians using decision aids (in effect, inducing
demand for decision aids).12
But none of these issues is high on the policy agenda
in Washington. Until incentives are realigned and providers have an incentive
to help patients make informed medical choices that are consistent with their
values toward benefits and risks, things are unlikely to change much.
It is clear, however, that patients’ desires to
be involved in their own medical decisions are likely to increase, especially
as baby boomers begin to age into more intensive consumption of health services.
Decision aids, especially those with rigorous and complete assessment of available
medical evidence, can help meet this need. And providing high-quality decision
support to patients before they are subjected to a major medical intervention
may be the best way to reduce unwarranted variations in care and the number
of costly treatments that have little value to patients.13 The
Foundation for Informed Medical Decision Making/Health Dialog arrangement
has found a market niche in a health care marketplace that remains dysfunctional;
it is hoped that innovative approaches will continue to evolve so that decision
aids can have even further reach.
The author acknowledges the thoughtful advice provided in reviewing
this paper by George Bennett, Chris McKown, Al Mulley, Jack Wennberg, and
Jack Fowler. Their dedication to the expanded dissemination of decision aids
is a remarkable testament to the strength of their convictions and will.
