Perspective:
When Excuses Run Dry: Transforming The U.S. Health Care System
Media attention alone is
not sufficient to spark a transformation;
real commitment and cultural change
are necessary.
By Leonard D. Schaeffer
and Dana E. McMurtry
ABSTRACT:
Mainstream media have reported on the wide variation
in clinical practice documented for years by health service researchers. Raising
awareness of the quality and cost implications of clinical variation, however,
is not enough to adopt clinical behavior based on the principles of evidence-based
medicine (EBM). Preoccupation with EBM’s limitations—which can
be overcome—and failure to address its misperceptions inhibit transformation
to an evidence-based system of care and payment. Three reinforcing efforts
are needed: aligning payment with quality; increasing the engagement of consumers;
and accelerating investment in and adoption of information technology. Real
transformation in health care requires changes in both culture and attitudes.
The papers in this collection
add to the literature linking variations in clinical practice to wide differences
in quality of care and health outcomes.1 The
message is that aggressive short-term action is needed to implement a long-term
vision to accelerate translation of research into clinical practice. This long-term
vision aims to make evidence-based medicine (EBM) the “gold standard” for
care.2 Research
stretches back four decades showing gaps between what is known to work and
the care patients get.3 Excuses
are running out for maintaining a health system that fails to optimize quality
of care.
Reports by the Institute of Medicine (IOM) and RAND have
struck a chord with the public.4 The
media have begun to focus attention on these issues, but this alone is not
sufficient to change behavior and generate a shift to EBM.
Barriers to adoption
of EBM. A
review of the literature reveals that barriers to adoption of EBM can be classified
into two distinct categories: limitations and misperceptions.5 Limitations
include difficulties in applying evidence in the care of patients, the need
to develop new skills, limited time and resources, and lack of evidence that
EBM “works.” Most of the limitations cited can be addressed through
training, new skill development, and acquisition of tools that provide decision
support at the point of care. The notion that EBM lacks evidence is refuted
by consistent findings that patients receiving proven therapies have better
outcomes.6
Many of the limitations to practical application of EBM
are no different than the everyday challenge physicians face as scientists
whose work has an experimental and changing basis.7 Most
physicians recognize that the potential to provide their patients better care
resides in the ever-growing body of clinical research. The challenge for the
system is to translate research into common protocols for specific diagnoses,
disseminate the information widely to help physicians stay current, and create
incentives to promote application.
Misperceptions of EBM as a “cost-cutting” tool
benefiting payers or a “cookbook” approach that treats every patient
exactly alike inhibit efforts to put research into practice.8
These misperceptions foster provider distrust, provoke unnecessary defenses
of unfettered professional discretion, and create barriers to institutionalizing
evidenced-based interventions that would improve outcomes and lower the avoidable
costs of poor quality.
Misperceptions of EBM may stem from lack of a common definition.
EBM is not a new concept, but older definitions overemphasize the requirement
to use statistical evidence in making clinical decisions about the care of
individual patients. EBM today acknowledges that a physician’s best care
combines guidelines based on scientific data, the physician’s own experience
and knowledge, and an understanding of patients’ values and preferences.
Patients’ needs and responses differ, and physicians’ experience
is critical to discerning what works best, has the best compliance, and is
the most cost-effective.9 Greater reliance
on EBM would actually increase use of proven technologies and therapies and
reduce the overuse of treatments with insufficient evidence and marginal clinical
usefulness. Also, the research community should heed Helen Darling’s
call for comparative clinical effectiveness studies to help physicians combine
knowledge with their professional intuition.10
Transformation to
an evidence-based system. Growing
national attention to the importance of clinical quality emboldens those interested
in EBM. WellPoint and other leading health plans are already employing multiple
strategies that incorporate the principles of EBM. These include disease management/
health improvement programs, physician profiling, improved pharmaceutical and
therapeutic review processes, dissemination of quality information to network
providers, and collaboration with business and trade groups on quality initiatives.11
At issue, however, is that neither the media nor these
programs will be the change agent that establishes EBM as the foundation of
U.S. health care. Changing the economics of health care is what’s needed
to transform the system. For this reason, health plans’ responsibility
for financing health services naturally consigns plans to a change-agent role.
Plans can most effectively catalyze change in practices and behavior using
their unique position in the health care system as payers and intermediaries
of information.
In the current system, poor quality pays: Physicians are
reimbursed for both incorrect treatment and effective therapy.12 They
are also reimbursed for care that may not inflict actual harm but may be duplicative
and of marginal clinical value or may put the patient at risk. Patients, too,
contribute financially to questionable care. A potent way of reducing tolerance
for low quality throughout the health care system is to migrate toward a quality-based
system of payment.
Transformation to an evidenced-based system of care and
payment requires three changes to the status quo: (1) aligning payment with
the provision of high-quality care; (2) motivating patients to become better
health care consumers; and (3) accelerating the investment in and adoption
of information technology (IT) that supports compliance with and further development
of EBM. Ideally, all three changes should occur in rapid unison. Health plans
recognize, however, that consumers and providers prefer to act voluntarily,
usually in reaction to subtle incentives—a social value resulting in
incremental change to U.S. health care.
Mindful of this social value, health plans are targeting
financial incentives at physicians and patients—the two parties who share
(or should share) clinical decision making—as a first step toward new
quality-based payment models. At the same time, there is a need for health
IT that supports exchange of clinical and administrative data among providers,
patients, and plans. More sophisticated IT and more standardized data definitions
are a prerequisite to sustaining changes in clinical practice and office workflows
that make better care possible.
Aligning payment with quality. WellPoint
and other leading health plans have implemented voluntary physician incentive
programs to pay for quality because physicians accept this approach. Our experience
demonstrates that incentives can prompt physicians to change their clinical
behavior. Bonus payments can also influence physician groups to install IT
to measure quality, improve care, and reduce errors.
The reality of pay-for-performance, however, is that the
size of the incentive matters. The extra revenue is a function of how many
members a physician sees from a particular plan. The incentive and enrollment
must be sufficient to alter behavior and spur quality investments in the office.
For this reason, Bradley Strunk and Robert Hurley observe that raising the
bar on quality throughout health care will depend on “plans with larger
market share who are more likely to succeed than efforts by smaller plans.”13
Rewarding providers who demonstrate quality is important;
rewarding providers who demonstrate quality improvement will become even more
critical to moving the dial on quality. The biggest challenge for maturing
pay-for-performance programs will be finding acceptable ways to provide incentives
for physicians who are reluctant to change clinical behavior or use IT associated
with higher quality.
Creating better consumers. Consumers
are as disconnected from decision quality as they are from the true costs of
care. Annette O’Connor and colleagues define “decision quality” as
patient participation in clinical decision making. The lack of such participation
results in the overuse of options that patients do not value and higher health
care costs.14 Helping
patients make value-based choices is emerging as a key strategy for both quality
improvement and cost containment.
The current system cocoons patients instead of encouraging
them to actively participate in decisions about their own care. Lack of consumer
engagement in cost-effective care perpetuates a supply-driven model of insatiable
and unaffordable demand. Consumer engagement isn’t code for “increasing
cost sharing.” It means helping consumers become informed so they can
factor in their values when evaluating the benefits versus the harms of different
treatment options.15
The onus is on health plans to develop benefit designs
that encourage consumers to value clinical quality, insist on shared decision
making, and accept the responsibility to bear the results of choosing lower-quality
treatment options. This should not, however, deter patients from seeking needed
care.
Accelerating IT adoption. Long-term
quality improvement requires accelerating the adoption of health IT systems
throughout the health care system. Health IT is needed to facilitate the flow
of clinical information, integrate and analyze data to generate performance
metrics and new information, and transfer that knowledge back to empower patients
and change clinical behavior.
Momentum is clearly building to implement interoperable
IT systems that can make health care safer. Credible studies show that an unacceptable
number of patients die from medical and hospital errors each year.16
The good news is that electronic prescribing demonstrations are showing dramatic
reductions in the errors responsible for many deaths.17
Unfortunately, some stakeholders focus only on the methodological limitations
of this research. This dilutes calls to action and fosters a “culture
of denial and complacency.”18 It
is clear that only combined and sustained public- and private-sector efforts
will eliminate resistance to wider adoption of health IT.
Government can wield its purchasing power to this end.
The electronic prescribing requirements to support Medicare Part D, for example,
will help quicken the pace. WellPoint’s experience with its $42 million
Physician Technology and Quality program shows that health plans capable of
large-scale initiatives can also “seed” the physician market with
health IT. This program gives physicians a free gift of either a handheld electronic
prescribing device or a computer system designed to help them participate more
fully in the electronic medical community.
Multiplying similar private-sector efforts to improve clinical
decisions would reduce variation, create a spillover of high-quality care to
more patients regardless of their carrier, and tip the system toward evidence-based
care. The WellPoint Foundation recently established the Center for Health Care
Economics and Technology to encourage such private-sector efforts.
Changing values and
attitudes. Large-scale
change within systems is not easy. Yet it is sobering to read Fitz Mullan’s
interview of Jack Wennberg, which reminds us that he and his colleagues have
documented treatment variation since 1973.19 Their
key insight back then was that the paradigm of ongoing translation of science
into effective care was a myth. There are now many more treatment options with
important trade-offs for patients to understand if they are to share in making
clinical choices.
The real transformation in health care will be changing
values and attitudes. A culture is needed that demands to know how we can reduce
variation through EBM, not why we can’t. We have the tools, incentive
strategies, and attention of stakeholders that can be leveraged to break down
the barriers that paralyze progress. Above all, we have the obligation to assure
broader access to affordable coverage.
