More Medicine Is Not Better Medicine (cardiac heart bypass surgery)
By ELLIOTT S. FISHER
HANOVER, N.H. — No one in Washington is completely satisfied with the
Medicare legislation that Congress approved last week. For many
conservatives, the shift toward private health plans is too limited; for
many liberals, the new prescription-drug benefit is too stingy. Yet almost
everyone agrees that the current bill worsens the program's long-term
financial stability.
Constructive debate about Medicare's costs, however, is hampered by a flawed
assumption that both helps and is reinforced by the health care industry:
that more care — and more expensive care — is better care.
The difference in spending is almost entirely due to the way medicine is
practiced in high-cost regions. Compared with similar patients in Portland,
Medicare enrollees in Manhattan spent more than twice as much time in the
hospital and had twice as many doctor visits per year. The additional
services provided in higher spending regions are largely discretionary, like
more frequent visits to specialists, longer hospital stays and more frequent
use of diagnostic tests and minor procedures. Remarkably, more spending does
not lead to more people receiving expensive and proven treatments, like
cardiac bypass surgery or hip replacement.
What was surprising is that quality was actually somewhat worse in regions
that provided more care, with less frequent use of proven treatments for
heart attack patients and of preventive services. Meanwhile, access to care
and satisfaction were worse or no better than in regions that provided less
care
Better information will allow us to get the incentives right. The backlash
against "managed care," which was evident in the Congressional debate over
Medicare, has been driven largely by the fear that beneficial treatments
were being denied because doctors were paid more to provide less. But
unmanaged care and unfettered growth can also be dangerous. If health care
organizations were held accountable for improving the quality and efficiency
of care, patients might believe that excellent care and lower costs are
compatible.
Our study suggests that perhaps a third of medical spending is now devoted
to services that don't appear to improve health or the quality of care — and
may make things worse. It also shows that we have sufficient current
capacity to cover the uninsured — without necessarily increasing spending.
(All that would happen is that the well-insured would see their doctors less
often and, perhaps to their benefit, spend less time in the hospital.)
Members of Congress are right to be concerned about increases in federal
spending. The debate over Medicare underscores the challenge: how to pay for
better care, not just more care.
