“Comparative Effectiveness” and Rationing
By Roger
Stenson
As one
medical journal article describes it, “The basic idea underlying the
QALY [Quality-Adjusted-Life Year] is simple: it assumes that a year
of life lived in perfect health is worth 1 QALY (1 Year of Life × 1
Utility = 1 QALY) and that a year of life lived in a state of less
than this perfect health is worth less than 1. ... By moving away
from a purely biological model ... a need arises to focus on areas
such as the individual’s ability to operate in society [and]
disability.” Some measures have “negative ... scores for health
states perceived as being worse than death.”
In a
featured piece in the July 19 New York Times Magazine, Princeton
bioethicist Peter Singer openly advocated government rationing of
health care, using QALYs. He made it clear that society should be
more willing to withhold treatment from those who are old and those
with disabilities.
“The
death of a teenager is a greater tragedy than the death of an
85-year-old, and this should be reflected in our priorities,” he
wrote. “[S]aving one teenager is equivalent to saving 14
85-year-olds.” Similarly, “If most would ... choose 6 years of
nondisabled life over 10 with quadriplegia, but have difficulty
deciding between 5 years of nondisabled life over 10 with
quadriplegia, then they are, in effect, assessing life with
quadriplegia as half as good as nondisabled life.”
In one
example in the medical literature, an attempt was made to assess
different quality-adjusted life year scores for each of the
following: “no physical disability, limp, walk with crutches, and
need a wheelchair.” In another, the authors wrote, “[I]t may be
judged that one year of life with a moderate disability is
equivalent to 0.75 years of life at optimal health.”
The
assumptions built into the use of quality-adjusted life years are
often inaccurate. As Hayden Bosworth of the Duke University Medical
Center documents, “Patients who have not experienced a stroke ... or
individuals at risk for future stroke ... respond with low [quality
of life] estimates for physical impairments. Yet it is clear that
patients who actually experience a high level of impairment as a
result of a stroke provide high estimates of their quality of life.”
How could
comparative effectiveness research using quality-adjusted life years
be used to deny treatments needed by people with disabilities? Mark
Pauly, a professor in the Department of Health Care Systems at the
Wharton School of the University of Pennsylvania, advocates “a
bottom-up strategy in which the plan set a target level for spending
growth and then used cost-effectiveness analysis to choose the set
of new technologies whose cost fit within the limit and which
maximized the number of new QALYs delivered. At the limit, a
technology would be in the package only if its value of dollars per
QALY were lower than that of all excluded technologies.”
