SESSION 5: CHILDREN AND CLINICAL RESEARCH
DR. PELLEGRINO: Good morning. We've
got some members missing but we'll just move ahead. When they hear
our dulcet voices, they no doubt will come in, as long as we keep it
dulcet. This morning our first speaker is Tom Beauchamp. Tom is a
member of the Kennedy Institute of Ethics but more famously the
co-author of the most popular book in biomedical ethics in the world, I
guess, and of course, beyond that a Yung Scholar as well. But I'm
not going to go into all his credentials. As you know, that's
available and we'd like to keep our introductions short and I know
Tom appreciates that as well.
We've asked Tom, who was a member of
the Belmont Report Committee, played a prominent role as you all know,
to give us the present status of the Belmont Report, what's
happened since then, with particular emphasis on children, our concern
this morning. Tom, can you take it from there?
DR. BEAUCHAMP: Is that all right? Can you
hear in the back, Marti? Good, okay. Many of you know that I have
had a long association with Ed and Alfonso, a member of my department
for how many years, Alfonso?
DR.GÓMEZ-LOBO: Thirty or so.
DR. BEAUCHAMP: Thirty, right, and also with
Rebecca Dresser, my dear friend and co-author and I believe Rebecca
will not be here today, as I understand it and I'm very sorry
about that. I'd like to tell you that when Ed called me I was
really very worried about what time he was going to call this meeting,
because Ed just decided we'd find out when we were free during
the day and Ed would say, "Well, I'm here at 5:00 o'clock,
how would that be?" I was afraid he was going to ask me to
be here at 5:00 o'clock this morning. So this is a very decent
hour to get started.
I should also say in the spirit of
disclosures of the sort we're supposed to make these days, that I
have a long, long, long history with Bob Levine and that history is, in
some respects so close that we might even sound like we're speaking
from one voice. So it's not as though you get very different
characters when you have us around at the same time.
All right, so let's get down to business. I'll stay fairly
close to my text. I like to do that because otherwise I depart
and stray and digress and I don't want to do that. This morning
you've given me a time limit and I'll try to stay within
it. I trust you being very good about time, you'll nudge me
if I'm going on too long. Okay. Ed and Dan have asked me to
discuss my quote "Views on the Belmont Report as the ethical
basis for the regulatory framework governing clinical research in
this country" and then to generalize beyond that circumstance
to the quote "regulatory framework governing clinical research
ethics" and then to include my own view of quote "the
current state of the ethics of research with human subjects",
and I understand that that means in terms of the historical continuity
with what happened back in the 1970s. So I will try to stick reasonably
closely to this assignment.
I will state what I believe really
happened when the Belmont Report came into existence, how it captured
some reasonably deep and significant themes in research ethics and how
some of this might still be of help today. I will then, at the end, as
I understand my assignment, offer you some recommendations based on
what I have said. Recommendations are, of course, just that.
They're recommendations. So let me talk first about the National
Commission.
As is reasonably well-known, the National Commission was established
in 1974 by the U.S. Congress with the charge to identify the ethical
principles, that was in the charge, that should govern the conduct
of research involving human subjects and to develop guidelines for
the conduct of research. It was hoped that the guidelines would
insure that the basic ethical principles would become embedded in
the research oversight system of the United States. Its more than
100 recommendations, the Commission's recommendations for reform,
went directly to the desk of the Secretary of the Department of
then Health, Education and Welfare and many were codified in federal
regulations. You know them all well, there's US 45 CFR 46.
The Belmont Report is not itself written in the style of federal
regulations or anything even approximating it and was never so codified.
The Belmont Report is a tiny philosophical document for the most
part. Carol Levine offers the following sobering but I believe
accurate statement of the historical context in which the National
Commission deliberated. I quote her, "The Belmont Report reflected
the history of the 30 years immediately preceding it. This emphasis
is understandable given the signal event and the modern history
of clinical research ethics, that is to say Nazi experimentation.
American public opinion was shaped by the revelations of unethical
experiments such as the Willowbrook Hepatitis B Studies, the Jewish
Chronic Disease Hospital Studies and especially the Tuskegee Syphilis
Study. Our basic approach to the ethical conduct of research and
approval of investigational drugs was born in scandal and reared
in protectionism. Perceived as vulnerable, either because of their
membership in groups lacking social power or because of personal
characteristics suggesting a lack of autonomy, individuals of that
sort were the primary focus of the Commission's concern,"
close quote.
I want to go now — I want to go in a
moment directly to the Belmont Report but I know that you are now
thinking about children and I want to start with the Commission's
Children's Report, still a document, I believe, well worth your
reading, and a problem in that report that kept coming back over and
over again during the National Commission's deliberations. This
problem was never resolved adequately or fully or whatever the term
should be, nor is it likely that you will resolve it here during your
deliberations. It is a deep problem that will always be around.
But it captures, I think, one of the great
questions of research ethics and one with which you must grapple
because it's unavoidable. I will not summarize or interpret any
document. I want to go to the moral heart of what I understand the
debate to have been about and in this way to offer you an understanding
of what the Belmont Report is about. I think this problem could easily
become the center of debate for you as well. But historical
understanding is important in its own right, a view that I have always
shared with both Alfonso and Ed. Alfonso, as you may know, is a
historian of philosophy and so am I, in our own way. I take historical
analysis of that sort with very great seriousness and I think it's
important to look at the history of bioethics in much the same way.
So I take fidelity that history is my
first obligation in what I'm about to say. In 1975/'76, the
National Commission deliberated on the topic of research involving
children and eventually produced a volume on the subject, one written
and published well before, before, the Belmont Report. It is easily
the most important of the Commission's 17 volumes for an
understanding of why Belmont takes the shape that it does. Belmont was
forged in the context of discussing research involving children. I
know that because I wrote it. I know exactly how the context was
forged. Without this background, I think you lose something.
By the way, I wrote almost all the Belmont Paper. Bob Levine
wrote the section on boundaries in that paper so that you know how
the authorship — because it was revised many, many times by
the Commission. You know the process well. For about a year, no
exaggeration here, the Commission found its deliberations grinding
to a halt over a significant moral problem; how much danger or risk
could justifiably be presented to children in so-called at that
time non-therapeutic or non-beneficial research? On one side of
the debate were the apparent defenders of research. They argued
that severely restricting the involvement of children would bring
pediatric research to a standstill, with, of course, grave consequences
for children who would be sick in the future.
On the other side of the debate were the
apparent defenders of research — I'm sorry, children. They argued
that openly using children with exposure to significant risk when the
intervention was not therapeutic or of direct therapeutic intent, was
to use persons without their consent to the ends of science. Children
would be, in short, exploited without any benefit flowing to them for
their sacrifice. During this debate, most Commissioners found
themselves somewhere in the middle of the two sides and reluctant to
choose sides. So how to bring a very long body of deliberations to a
conclusion?
Ultimately the defenders of research would
be, so to speak, victorious although I'll be careful about that
word in this debate, but with two dissenting votes among the 11
Commissioners and two dissents filed. The most difficult ethical
issues for the Commission arose with respect to research presenting
more than minimal risk, where there is no immediate prospect of direct
benefit to the individual children involved. Some members of the
Commission urged that the limit for such research remain at the level
of minimal risk. Others pointed out that such a limit would almost
certainly eliminate much research that has genuine scientific
significance as well as the promise of substantial long-term benefit to
children in general.
Ultimately the Commission decided with two
members dissenting, that if three conditions are satisfied, research in
this most difficult class of cases could be justified. First, the risk
must be only a minor increment beyond minimal. Second, the procedures
to be used must be reasonably similar to those with which prospective
subjects have already had some experience. Third, the research must be
likely to yield generalizable knowledge important for the understanding
or amelioration of the specific disorder or condition.
Thus, foreseeable benefit in the future to an identifiable class,
class, that was the key notion that was landed on, of children was
held to justify a minor increment of risk to research subjects.
Dr. Robert Cook then Chancellor of the Medical System in the State
of Wisconsin, objected vigorously to these conclusions and, as I
understood him, he objected to the moral premises underlying them
as well. He wrote as follows in his formal dissent. Quote, "In
the ethical justification of its recommendation, the Commission
can invoke only the principal utility. This, in itself, does not
constitute any breach of ethics but it does indicate the perilous
nature of the recommendation and the ethical uncertainty of the
Commission." Lawyer, Robert Turtle, was even tougher on his
fellow Commissioners. He says in his dissent, that the Commission
notes that it was, and I quote, "Impressed by reported examples
of diagnostic therapeutic and preventive measures but," Turtle
says, quote, "that rationale provides no basis at all for segregating
children in to separate classes. The rationale is strictly utilitarian.
I do not believe a strictly utilitarian rationale can provide adequate
justification for a policy creating a doubly disadvantaged class
of children, doubly disadvantaged because they're already sick
and you — they're sick and then you add an additional risk
on top of their sickness."
I agree with the minorities'
interpretation, the Commission had reasoned heavily by appeal to
considerations of public utility, but this was certainly not the only
evaluative commitment of the Commission and it would misunderstand the
deliberations and its moral commitments to cast its conclusions in this
narrow way. The historical record and transcript clearing indicates
that the National Commission, was very concerned throughout its work
that it had become too easy in the biomedical world to use utilitarian
justifications of research. The Nazi experiments, Tuskegee and Jewish
Chronic Disease Hospital case, all the cases that were very much on the
horizon and being examined at the time, had left a legacy of being
driven by a very utilitarian view of social beneficence, the justified
using human subjects on grounds of benefit to the broader public.
That is, a major purpose of the report, of
the Commission's Report, was to properly balance the rights and
interests of subjects with those of science and society.
Considerations of autonomy, justice and risk control were set out to
limit utilitarian balancing, explicitly so, that's why these
considerations are there, not to promote utilitarian balancing.
However, it is doubtful that the question of how best to control
utilitarian balancing was ever resolved with the Commission and, in
truth, I do not believe that it has ever been resolved by anyone in
bioethics. That is the theme, so to speak, of my talk today to the
extent that it has a theme that cuts across all of its sections.
Now, to the Belmont Report. When I wrote
most of the Belmont Report for the National Commission, what I have
just explained to you was the framework of deep issues that was always
before me. These concerns had already been laid out by the history of
the Commission's deliberations, most clearly, I believe in the
children's report. So it was easy for me to grasp the nature and
importance of these questions, in other words, people have already done
the work for me. I never forgot this context for even a single
sentence when I was writing that report.
But before I explain this background
further, I should state what the Belmont Report is known for and how to
interpret its framework of basic principles. These principles are
still today referred to in many contexts as the Belmont Principles and
rightly so in my view. The Commission identified three general
principles as underlying the conduct of research; respect for
person's beneficence and justice. These principles, though often
quoted in bioethics have often not been well understood because the
historical context has been dropped in the invocation of the
principles. I will cite a simple example which will be readily
understandable to you and it will also, perhaps, motivate you to find
the historical context I'm now drawing out a little
better.
On page 19, Roman 19 of your Volume "Being Human," there
is a brief discussion of these principles. And I think you wrote
that, Leon, am I right or did you all write it together? I'm
not quite sure how that worked.
DR. KASS: The report?
DR. BEAUCHAMP: Yeah, the introduction to the
report. It doesn't matter. That was my understanding but it
doesn't matter. The principles that are there said to be; and
I quote, "The major principles of professionalized bioethics."
The principles are then explained. They are explicated wholly in
terms of the patient, for example, as discussed here, patient autonomy,
and also in terms of distributive justice in the health care system
as well as in terms of public health. There is no mention of research,
not even a hint of it. The oddity of this to me is that these principles
were born and bred in a research context. That is where they came
from.
The concerns were not about patients, per
se, but about subjects. The concerns about distributive justice were
entirely about the fairness of the selection of human subjects, not
about distributive justice in the healthcare system. In other words,
the embeddedness of these principles in the history of research in the
1970s is easy to lose and it has for the most part simply dropped away
in the contemporary understanding of what these principles are. And
yet, if you're going to understand that Belmont Report, that is the
only way, I believe, that it can be understood.
And so if we're to understand the
National Commission and what it brought to be codified in federal
regulations, as well as the connection of this history to the
development of research ethics over the course of the last 30 years, it
is truly important to understand not only the principles but what gave
birth to them and the original context of their birth. This is what
I'm trying to accomplish now. There's a key organizing
conception underlying the Commission's presentation of their
principles and use. The simple conception is the principle of respect
for persons, commands in the research context, obtaining informed
consent, be it first party or be it third party. The principle
beneficence commands that a risk/benefit assessment be done and that it
not be a narrow one but a broad one.
Justice demands that you pay — the
principle of justice demands that you pay very careful attention to the
way in which subjects were selected so that that selection process be
fair. That's in outline, the essence of what the National
Commission was about in constructing these principles as the framework
of what it had morally done. In this way each principle makes moral
demands in a specific domain of responsibility for research. Here is
what is noteworthy. Beneficence in the world of biomedical research is
very different than beneficence in the context of patient care where it
is confined almost exclusively to the medical welfare of the patient.
In the research context, beneficence has to be understood and should be
understood in terms of benefit to the public and the social imperative,
so to speak, of biomedical research. Quite explicitly the principles
of respect for persons and justice in the Belmont Report are not in any
respect whatsoever to be allowed to be brought under the context of or
to be subordinated to public beneficence. That was the architectonic
of the document.
Those two principles, axioms and the
framework, so to speak, are erected intentionally at the heart of the
National Commission's moral framework to serve as moral constraints
on beneficence, to be just as important as social beneficence, what
some philosophers like to call the ontological constraints. The whole
point of this framework is that neither of these principles is to be
compromised or lost under public beneficence, medical research,
ambitions and the like. The Commission spent a huge amount of time on
the place and purpose of informed consent.
In historical context, there wasn't
much informed consent at the time or much of an understanding for the
notion, for that matter. The Commission insisted that the purpose of
consent provisions is not protection from risk. Indeed, that
risk/benefit and their balance is wholly the wrong way to understand
the place of informed consent.
I've heard it often said in both the
United States and Europe that there has been an over-emphasis on
autonomy in the frameworks spawned by the National Commission,
sometimes expressed in Europe as an American obsession. I think this
is false to the historical facts and I think it shows no insight into
the history of bioethics. The National Commission was as concerned
with personal dignity as it was with autonomy and this is one reason
why its first principle is the principle of respect for persons.
However, I don't want to carry on about this subject as at this
point, it would take us too far astray. Back to the main theme.
We have seen repeatedly throughout the history of research involving
human subjects that we cannot avoid coming to some form of delicate
balancing of the human values that we attempt to collect and then
distill in the form of principles expressed in the biomedical —
in the Belmont Report. We then must contextualize balance and specify
their significance when we confront particular issues such as those
that confront us with children. The Belmont Report was written
in significant part to try to insure that we appropriately balance
appeals to social utility in the justification of research together
with respect for persons and considerations of fairness.
If you lose that perspective, in my view, you lose almost everything
of real and enduring importance about the history of the National
Commission and much of the history of recent research ethics. The
whole of the work of the National Commission, all 17 volumes, came
to one fulcrum; how to balance and specify the moral considerations
that it called, following the mandate of the U.S. Congress, principles,
as those principles could be brought to bear in problems arising
from research involving vulnerable groups, that is after all what
we were up to: embryos, prisoners, the institutionalized, mentally
infirm, children and so on.
I want to say just one more thing about the Commission's framework,
by the way, how am I doing on time, before ending this first part
of my assignment? The principle of justice in Belmont requires
fairness in the distribution of both the burdens and the benefits
of research. The Commission insisted that this principle requires
special levels of protection for vulnerable and disadvantaged parties
but that attention to questions of distributive justice should always
remain at the forefront of research ethics.
This principle demands that researchers
first seek out and select persons best prepared to bear the burdens of
research, for example, healthy adults, and that they not offer research
only to groups who have been repeatedly targeted, for example, mentally
retarded children. The Commission notes and laments that historically
the burdens of research have been primarily placed and indeed heavily
so on the economically disadvantaged, the very sick and the vulnerable,
owing to their ready vulnerability and availability. Yet, the
advantages of research are calculated to benefit all of us in society.
The over-utilization of readily available, often compromised segments
of the US population was a matter of the deepest moral concern to the
Commission throughout its deliberations. The theme of justice and the
proper selection of subjects was Belmont's way of saying that since
medical research is a social enterprise for the public good, it must be
accomplished in an inclusive and participatory way.
If participation in research is unwelcome and falls on a narrow
spectrum of citizens because of their ready availability, then it
is surely a questionable enterprise. Sadly, the Commission never
got much beyond these themes of justice but what the Commission
did is still a good start and I will return in a moment to these
questions of justice and explain this a little further. I conclude
this little historical discussion as follows. The Belmont Principles
are in some respect present in every document the National Commission
published. These came to be the backbone of federal law in the
area. From this perspective, as Christine Grady has observed in
her recent book and I quote her, "Probably the single most
influential body in the United States involved with the protection
of human research was the National Commission." I believe
that she is right. Biased as my judgment may be, I think Christine
is right about this. But whatever the influence and enduring legacy
of Belmont and the Commission's other reports, it is not clear
that scientists who today are involved in research with human subjects
are really familiar with the Belmont principles or understand them
or for that matter actually use them.
When the National Commission deliberated
it seemed to many at the time that the general system in the United
States of protecting human subjects was in need of serious repair, that
research investigators were not educated about research ethics and that
subjects were not adequately protected. To some observers, the system
still seems today caught in a notably similar state of disrepair, I
mean right now. I am not here today to make any judgments about this
claim as I'm really unqualified to do so. It takes a different
kind of knowledge. I say only this; it would be a shame if you, a
great national deliberative body, could not find the time to figure out
where we are today and to do as much as possible to remedy defects in
the system.
With this general perspective now out in
the open and before us, I will turn to my recommendations to you based
on what little I do know of the system today, what might be important
to you and the history that I have just sketched. So at the risk of
reducing myself to a kibitzer that you, perhaps, think I am anyway, I
have several things to recommend and in four areas.
First, the research oversight system; some
in bioethics have argued that problems with research ethics are largely
a matter of getting just right how to adjust the present oversight
system for clinical research in the United States, which supposedly
protects subjects against excessive risk and exploitation while
demanding scientific rigor and promise. If the system fails, this view
goes, then to avoid moral problems, we need to patch up or reform the
system. This view puts tremendous weight on the oversight system that
we have and it is this that I suggest you be cautious about. There is
no evidence that research oversight systems have a particularly good
grasp on various moral problems of research ethics. And in any event,
I don't think the oversight system is the only way to process or to
present these problems.
Moreover, in a globalized world, one needs
to think globally irrespective of a particular country's system of
oversight. There are many oversight systems. I do not, myself, assume
anything about the adequacy of oversight systems in thinking about
research ethics and I recommend that you not make any such assumptions
either. Frankly, many people now believe that the system of protection
we've erected in the United States stinks and is in need of deep
reform. I take no position on that issue before you today. If you
wish to get into this, I would applaud the effort. At the same time, I
do not think that moral problems should be confined to this arena.
Performing the IRB system and the like could wholly consume your time
for months and months. Try to think far beyond this to the underlying
moral views and how to present them clearly.
Second area, problems of justice which I
said earlier I would return to. The National Commission came into
existence in the aftermath of public outrage and congressional
uncertainty over the Tuskegee Syphilis experiments, the Willowbrook
experiments and other apparently questionable uses of human subjects.
The socio-economic deprivation of the subjects who had been enrolled
in the Tuskegee experiments and involved at Willowbrook made them
vulnerable to overt and unjustifiable forms of manipulation at the
hands of health professionals.
What we know today about the recruitment and usage of human subjects
is less than I would like us to know, at least I believe it to be.
What do we know about that system, including how children are used
in it? This is an empirical question that I hope you spend the
time to investigate. I am not an empirical scientist but I suspect
from a survey of the literature that less is known than people often
believe. Since I am no expert, I say only this; consider what we
know about economically disadvantaged persons in the United States
today. Several issues are apparent. Are those persons, when used
as subjects, vulnerable to morally objectionable forms of involvement
in research? What kinds? Where, where does this occur? If so,
what is it that renders them vulnerable? Is it morally permissible
to trade off some level of risk and research for some benefit such
as money or health care?
Answers to these questions are not readily available and they are difficult.
It is also not clear which populations, if any, if any, should be
classified as vulnerable. Discussion of issues about the vulnerability
of research subjects, so-called vulnerable groups, have historically
focused on embryos, fetuses, prisoners, children, psychiatric patients,
the developmentally disabled, those with dementia and the like.
Until recently, relatively little attention had been paid to populations
of persons who possess a capacity to consent but whose consent to
participation in research might, nonetheless, be compromised, invalid
or unjust. Prisoners have been the most frequently mentioned class
of such persons but there could be many other such populations,
especially among the economically disadvantaged. It is known that
persons of this description are involved in some research in North
America though the extent of their use, I believe is not well understood.
It is also known that persons of this description are used in other
parts of the world, sometimes in so-called developing countries.
The scope of their use there is even less
well-understood and reported and I believe that to be the case with
children as well. I recommend that you look into such questions with
some care but these are not the only issues of justice that you may
wish to consider. One of the major problems of research is the
potential injustice that occurs when a benefit is generated for the
well-off through a contribution to research made largely by
disadvantaged members of society including potentially many children.
Research, as currently conducted, places a
minority of persons at risk in order that all, sometimes only the
well-off, might benefit, but how the burdens of research involvement,
if they are burdens, if they are burdens, a much under-discussed
problem, are to — how those burdens are to be distributed across
society has never been established in any authoritative code, document,
policy or moral theory known to me.
Nothing in federal policy, to my
knowledge, speaks to it. The notion of equity, commonly invoked in
these discussions, is poorly analyzed and even more poorly
implemented. As a result, it remains unclear and controversial when a
practice becomes a morally objectionable marginal form of coopting the
economically disadvantaged for the benefit of the privileged. I
strongly recommend then, that you do your very best to understand this
situation and provide remedies as it is possible for you to do so.
Considerations of justice suggest that society should take a far
greater interest in these individuals than it often does, not because
they have become or might become research subjects but because of their
status as economically disadvantaged and exploitable members of society
at many levels. There are here many unresolved questions. For
example, there are questions about the disproportionate use of the
economically disadvantaged, emphasize disproportionate there.
It may be appropriate to have selection
criteria so that the research enterprise does not so frequently use the
economically disadvantaged or any vulnerable population for recruitment
of subjects and that it set, as a goal, that the percentages of the
economically disadvantaged subjects in research be restricted while
insuring that research subjects are drawn from suitable diverse
populations. This was a great concern to the National Commission but
frankly, we never adequately resolved that problem or, in my view,
addressed it. I'll say something more about that in a minute.
This does not imply that it is always unfair to recruit even heavily
from an economically disadvantaged population. I suggest only that
certain patterns of recruitment and enrollment introduce problems
of distributive justice. Diversity in a subject pool might protect
against several conditions that might otherwise too easily be tolerated
in the research process; for example, that studies would be conducted
in dreary, inhospitable and even inhumane environments. That the
same subjects would be repeatedly used in such studies and that
a dependency on money would set in so that subjects would become
dependent on studies for their livelihood. A related problem is
whether it is problematic for individuals to be repeatedly involved
in multiple studies, a problem that presumably would be exacerbated
as financial inducements are increased to be involved in those studies.
Let me conclude about this part about
justice with this confession to you and that's what it is. I find
it somewhat painful to admit but it needs to be said. The idea of
justice in the Belmont Report and throughout the National
Commission's work is deeply under-analyzed. The problems are not
well-developed and the answers are thin. This is my own personal
failure as well as the failing of the Commission and I take full
responsibility for it.
What I am recommending to you is that you
take care not to find yourself in the situation I now find myself
before you today some years down the road. These are powerfully
important issues and they are difficult ones.
The third area I want to say something about, informed consent;
among the great worries about research at the very heart of what
the National Commission did or worries about inadequate or compromised
consent, the typical concerns center on whether the consent is adequately
informed of whether subjects have the ability to give an informed
consent. I'm not concerned now with the ability to consent.
That won't be where my comments go but rather with the process
used in the research context to obtain consent and the ways in which
consent can be compromised.
The most frequently mentioned problems of
consent in research are concealed data and inadequate discussion with
trial participants about risks and inconveniences, a common complaint.
Some practices of obtaining consent are clearly shams, where consent is
invalid even if a written consent document exists. However, there are
many more subtle and difficult problems of informed consent, including
ways in which information is presented initially and then throughout a
clinical trial. Without appropriate monitoring of consent, even an
initially informed and legally valid consent, can become uninformed and
invalid at least morally. I don't want to get here into the
business of constructing an appropriate framework for obtaining and
gaining consent in research but I do want to appeal to you to keep
practices of informed consent at the center of your investigations of
research ethics. The research enterprise and many of its parts still
must learn that informed consent, properly so-called is very often not
a single event of oral or written consent, but a supervised
multi-staged arrangement of disclosure dialogue and permission giving
that takes place far beyond the point of adequate oversight of a
protocol.
I am not convinced that this model is
deeply embedded in the research system in the United States still today
or elsewhere and I recommend that you look carefully at the problem,
including issues of consent or perhaps assent as we used to say in the
National Commission, by children themselves. Research that proceeds
without a voluntary and informed consent is simply an inexcusable
disregard of the right of subjects.
A final comment, I want to say something
about the political context of contemporary bioethics since you have to
operate in them, in some context of bioethics. I have a longstanding
disagreement with some of even my best friends in bioethics regarding
whether or not National Commissions, Advisory Committees, Presidential
Councils and the like have been and/or must be political bodies.
Crudely stated, the argument to this goes roughly as follows.
The political views of Commissions reflect
their political appointment sources which always have some political
edge to them, whether it be the President or Congress or whatever.
Whenever an issue turns in a political direction, it is reasonably
predictable what the outcome will be. There might be something to this
view, especially if it can be made subtle so that it is not cast too
broadly. Discussion of it needs to be placed in historical context and
made specific to particular issues, but this can be done by an
historically sensitive scholar. However, I do not, myself, believe
that this position is historically accurate or that things need to be
in this way as some people have told me they are.
I believe deeply that such a
characterization of the appointments to and the deliberations of the
National Commission is false to the historical facts. I believe it is
historical imagination getting in the way of real historical
understanding. But now, pertinent to your context here, it is surely
good advice that you protect yourself against the possibility of such
an interpretation of your work, most especially in the context in which
your charge is the protection of the interests of children and research
subjects in the United States.
Few things could be more distasteful even
disgraceful than a political arena for such discussions. I do not
believe that Ed Pellegrino would tolerate it for a minute. Indeed, I
do not believe that he would tolerate it in any arena. The problem
here, of course, is that there is, I quite agree, a sort of political
dimension to the work that you do. You can see that clearly emerging
right now, for example, in discussions of the TGM-1412 case of the six
London Hospital patients so tragically effected by an experiment gone
wrong. This is real human tragedy and what happened in London spanning
across four countries has to be sorted through very carefully.
We do not yet know, I believe, what
happened here. It is too early for judgment. But listen now to the
cacophonous voices reaching for judgment and speaking to the press with
their opinions. Look carefully at what has been said by so-called
bioethicists and others about this case. Watch the political jockeying
that is every day in the newspaper. It will pay you dividends to watch
this and not to make similar mistakes.
What I am recommending to you is that you
take every precaution not to find yourself in a comparable
circumstance. I think that is not as easy as it sounds, although
I'm personally pretty confident here about Ed Pellegrino's
leadership skills. So what I've been trying to tell you is how it
was at the National Commission and that's the way I deeply believe
that it was. This was not a political body ever. It was an anguishing
grinding struggle over the importance of scientific research and the
imperative to protect people from undue risk, but the National
Commission left many stones unturned.
There is a great deal for you to look
into and much hangs on it. Do it well, indeed, do it excellently.
I'm sorry, I couldn't avoid that last line, given so many
Aristotle scholars around the table. Thank you, Ed.
DR. PELLEGRINO: Thank you very much,
Tom. Dr. Beauchamp's talk is up to discussion and I have Dr.
Gomez-Lobo, Alfonso.
DR.GÓMEZ-LOBO: Thank you very much,
Tom. That was a very clear and affirmative exposition. Let me start
with an information question. And it has to do with the following; I
was wondering if we're so far away now from Tuskegee and
Willowbrook, et cetera, that some of the historical assumptions may
have changed. What I have in mind is this; yesterday, we heard
basically from Dr. John Lantos the following and I'm sorry I
didn't have a chance to have him give us a broader view of this,
but his claim was nowadays that the participation in a research project
may not only not be as risky as it was but even beneficial and his
claim was that in pediatric research subjects, that seems to be the
proper word, would fair better or did, in fact — do, in fact, fair
better than people who might have qualified for the research and
didn't. So there is this presumption that because of the care,
because of the concentration of efforts, probably as a result of
Belmont Principles, the scene may have changed and I would like to hear
more about that as a point of information about what's going on in
research.
DR. BEAUCHAMP: I'm sure things are
better and I would like to think they're better because of
documents like the Belmont Report. I would enter a discussion of this
with some skepticism about the point of view being quite as sanguine as
you just laid it out as being John's view.
I think actually we know very little about
this. How much does anyone know about what actually goes on out
there? We tend to pay attention to things like hospitals, academic
research context, clinics and universities. One of the things that
drops out of sight, would be very easy to drop out of sight with you,
for example, is corporate America. Stunningly little discussion of
what goes on in corporate America, but there may be — and even in the
case of a single CRO, there may be at any one time, as many as 100,000
subjects arranged for by the — at least these are the figures that
have been given to me.
There's a huge number of human
subjects involved in the research enterprise in this country. How much
do you actually know about that and I think the answer is relatively
little. I surely hope that things have been made much better in the
last 30 years but this is an empirical question. I can't really
answer it, because, I mean, I'm not an empirical scientist. I
haven't empirically studied this and that's the kind of
question that I see it. I think, though, when you see a case like the
TGM-1412 study that I just mentioned, you see what can erupt at any
time in the research context. Things can go very badly wrong. And you
may even not be sure why they went so wrong in that context. So though
I'm sure there are many, many studies where people are benefitted
by being in the studies and, of course, you can certainly imagine to be
not only in the case of the United States but in many other countries
as well, I'm sure there are such circumstances. I would ask — I
mean, I would be very reluctant to frame it in that way.
I would ask, yeah, but what about the
other circumstances?
DR. PELLEGRINO: Peter, Dr. Lawler.
DR. LAWLER: So I was — to follow up on
what Alfonzo said, I was thinking about the happy conclusion that Dr.
Lantos gave us yesterday that if you're in a heavily regulated
environment you're safer. So I will be safer later on this
afternoon when I'm flying back to Atlanta than I am sitting here
right now because then I will be in a more heavily regulated
environment. I mean, there's some truth to this. The studies do
show, so to speak, the safest place you can be in the world is on a
plane flying, okay. But this seemed — I agree, your skepticism
concerning this finally, that this doesn't simply resolve the
situation so we can now put burden in quotes, "the burden" of
being a research subject because it's not really a burden because
we should all want to be research subjects. It couldn't be this
simple.
So if I understood the beginning of your presentation correctly, there
is an irreducible conflict between what's best for the individual,
what's best for the person, and what's best for scientific
research. There is no way of coherently resolving this on the level
of ethics so all you can do is balance it in such a way as to minimize
the problem.
DR. BEAUCHAMP: Be constantly on guard for
it, yes, that's right.
DR. LAWLER: Right, so in other words,
there's no coherent ethical resolution to this problem given that
both of these interests in isolation are valid, the interests of the
individual person and the interest of science to progress which
everyone benefits from.
DR. BEAUCHAMP: Yeah, if I can comment on
that critically, I'm often astonished at the literature of
bioethics and the attempt to what we sometimes call hierarchically
structured principles or something else. I'm just astonished at
the idea that — this is not a knock at you — beneficence should be
above everything else or that justice should be above everything else
or autonomy above everything else. It's not the world and never
will be. I'm sorry.
DR. LAWLER: Right, so that seems very
reasonable. So your concern about justice confuses me a little because
—
DR. BEAUCHAMP: Confuses you?
DR. LAWLER: Confuses me. I think lurking
in your presentation is this premise, that citizens have a duty to
advance scientific research. That premise must be there because you
were against giving incentives to people to participate in scientific
research because that then would have too high a proportion of the
disadvantage —
DR. BEAUCHAMP: I'm sorry, I
didn't say either of those things actually, but go ahead.
DR. LAWLER: No, no, the — well, I think
you did implicitly because diversity is a goal in terms of subjects.
How exactly would you achieve this given that if you offer incentives,
those who are disadvantaged would be more likely to accept the
incentives?
DR. BEAUCHAMP: Well, I have a 30-page
unpublished paper on the subject that I will send to you if you would
like to see it. I think it is an extremely difficult problem. It is
way more — there's vast literature on undue inducements and undue
influence and that kind of stuff in bioethics, most of which I find so
confusing or incomplete that I really don't know quite what to do
with it. And I don't think it's something that we can really
get into.
I'd be happy to e-mail with you and,
you know, talk about it at some length. It really is a subtle and
difficult problem, more — way more nuance, I think than most people
have appreciated but no, I don't hold either of the views that
you're attributing to me, that you thought you saw in my talk,
sorry.
DR. LAWLER: Well, then I'm relieved,
thank you.
PROF. GEORGE: Dr. Beauchamp, I want to
take you to those comments that you made at the end on the — well,
really I think you're warning against the vulgar politicization of
advisory councils and ethics councils and so forth and I thought your
sound and subtle distinction between that and the sense of working in a
political environment that was inevitable and not of itself something
that needed to be rejected in any way.
A council like ours or any of these
councils, our predecessors, other councils does work in a larger
environment where there are particular elements of the society who are
paying particular attention. I think in the case of a council like
this and our predecessors one is particularly aware of the academic
world and particularly the bioethics academics who are interested in
the work of the Council, commenting on the work of the Council and so
forth and also the media. I mean, we'll open the newspaper on a
given day after a meeting of the Council and you know, there might be a
report, something in the Washington Post perhaps, something in
the New York Times and so forth.
Now, plainly you're right, I don't
think anybody would disagree that a council like ours really needs to
be careful to avoid politicizing itself or being politicized in that
vulgar and bad sense. My question is not about that. It's about
the steps that I think you were implicitly urging us to take to avoid
not only that vulgar politicization, but the appearance of vulgar
politicization. Now that, too, sounds right to me, since the effective
work of the Council depends to some extent not only on doing our job
well, but being perceived by opinion shaping elements of the society as
doing the job well.
But I would just ask for your reaction to
the following thought; it's not as if there are neutral observers
standing apart from a political environment and free of political
convictions and concerns of their own who are then assessing the
question whether the Council is politicized in the vulgar sense or is
doing its job well or is doing its job less well than it should because
of vulgar politicization. Rather there are political realities that
are describable about the people who are paying attention and writing
and seeking to shape opinion.
And my own experience with this Council is that in the end there's
very little that you can do that will enable you to avoid an allegation
of vulgar politicization where at least as in this case, you're
talking about a council whose members are appointed by a President
who holds very publicly and defends certain views which are just
out of step with major constituencies who are paying attention to
the Council and commenting on it in the public media, whether people
who are themselves professional pundits and commentators or people
who are in the academic world and particularly with the world of
bioethics.
Now, I guess I would not suggest that that
doesn't mean that the effort should be — that doesn't mean
that the effort should not be made, and by the effort I don't mean
simply the effort to avoid vulgar politicization, I think there's
no doubt that I mean, just as a matter of morality and virtue, that
should be avoided. I'm also saying, I guess, I don't think it
means that the effort to avoid the appearance of vulgar politicization
shouldn't be made, but I simply have my doubts about how much can
be done to avoid that.
Now, I could go through and cite examples
and give you chapter and verse and so forth, but I think you know what
I'm talking about and I'm wondering if you just have any
reaction to that thought and any concrete advice about whether there
are — whether I'm wrong and perhaps there are some steps maybe
things that we haven't thought about that could be taken on the
appearance question. Have I made myself clear?
DR. BEAUCHAMP: Yeah, I guess I'd like
a more richly drawn description of — it's almost as if you're
saying at one point in your comments you think it's difficult to
transcend the political context and I'm wondering, I guess, what
the underlying interpretation is there and what you think about that?
Do you think that the context is so political and you have to have
arrangements with such and such, the media, with let's say the
White House or whatever, such that you're unable to transcend that
political — to use the language of neutral observers was it, to become
a kind of neutral observer of your own situation and/or the political
context? Am I following you right? Is your view that strong?
PROF. GEORGE: I don't — perhaps I
haven't made myself clear. Whatever we do is going to be observed
and commented on by people who are interested in it.
DR. BEAUCHAMP: That's a given.
PROF. GEORGE: Okay, that's going to
be a given. That is, itself, part of a larger political world, the
elements of that commenting society.
DR. BEAUCHAMP: That's a given, too,
but not a world that you have to, so to speak, conform to. You have to
conform to its expectations and —
PROF. GEORGE: It's certainly true and
we haven't. I think it's fair to say we haven't conformed
to anybody's expectations. The Council has been, you know, quite
publicly very divided on many, many issues. We have managed to achieve
sufficient consensus to get out some reports that are valuable but in
very many cases, what the reports are doing is not defending a single
view, but putting forward the best arguments that we think are
available for competing points of view and the reason we're doing
that is that those points of view are represented on the Council.
But even those efforts seem not to be able
to persuade significant commentators on the work of the Council that
the Council is avoiding the kind of vulgar politicization that
you're, you know, rightly warning any council against. And I think
that's because people have political views and people have
political agendas beyond the — beyond the Council and there's
really very little we can do about that.
DR. BEAUCHAMP: There's nothing you
can do about that. You're stuck with that problem. I mean, you
just have to remain true to what you know are the right values, the
right kind of information that you should assemble, be sure you have
proper discourse and something that I personally think is very
important is not to be in any way intimidated by or unduly influenced
by any kind of political constituency and after that, what more could
anybody really expect of you?
If people then draw the conclusions that
they wish to draw because they have an agenda of some sort or an
ideology or whatever, there's nothing you can do about it.
They're free to say whatever they want to say.
PROF. GEORGE: Yeah, I think that's a
good answer and I think it's in a way a very important answer as
well, because it strikes me that there is a danger, your last comment
really highlights it, that a concern to avoid the appearance of
politicization in a certain sort of environment, might very well lead
you to take steps that are out of line with your substantive mission to
give the best possible advice on bioethical questions that we're
facing. And so, while the concern for the appearance of doing a good
job is important, you can't let that deflect you from actually
doing a good job.
DR. BEAUCHAMP: That's right.
DR. PELLEGRINO: Dr. Eberstadt and then
Dr. Meilaender.
DR. EBERSTADT: Professor Beauchamp, I
realize that statistics and quantification may not be your metier but
it's —
DR. BEAUCHAMP: That's for sure.
DR. EBERSTADT: — but it's kind of my
thing so let me torture you just a little bit or avoid torture as the
case may be. When we talk about minor increments beyond minimal in
terms of acceptable risks for subjects, patients, is there, in practice
any sort of literature that would indicate what is taken as acceptable
and what is taken as not acceptable risks in practice? A subsidiary
question there. I thought we had a very illuminating and valuable
discussion yesterday about the differences between harms and wrongs.
I can see how harm is amenable to
quantification. I'm not sure that wrong is amenable to
quantification in the same sort of way. Any thoughts about that? And
finally, just as a general observation, the mortality levels for
children in most developed societies are vastly lower than mortality
levels for adults. Does that suggest to people who are looking at the
question of minimal acceptable risk for children the standard for
children in absolute terms should be a much higher threshold than for
adults?
DR. BEAUCHAMP: A three-part question, I
guess. On minor increase beyond minimal, I would be embarrassed to try
to make an answer to your question when one of the world's leading
authorities is sitting in the front row back there. He knows more
about this than anybody that I know. But I will tell you this; it was
the view of the National Commission that it was not our job to try to
fill in exactly with great precision what that means. That was the job
of the IRB. That was the whole point of coming up with the conception
in the first place, which is to say, if you want to put it, you know,
rather negatively, nobody really knows what that means. It has to be
decided at the IRB level in the research context.
On harms and wrongs, it's always been
a very important distinction to me. It's a subtle distinction. I
think it's beautifully analyzed in the work of Joel Feinberg, if
you want to know sort of where I am on that issue and I guess I would
agree with what you said about that.
And the other was about threshold of —
DR. EBERSTADT: Minor increment beyond minimal,
acceptable, minor increment beyond — should there be a stricter
standard for children?
DR. BEAUCHAMP: The way the National
Commission went at that was to say we ought to use healthy adult
populations first. Now, is that the right view? I don't know. I
don't know that that is always the right view. So to harden that
principle may be the wrong way to go. Still, you've got to see
children in most contexts as more vulnerable than a healthy adult
capable of consent, knowledgeable about the situation, and so I
don't really know what much more to say about it than that.
DR. PELLEGRINO: Gil is next.
DR. LAWLER: Although his question was literally
because children are objectively less vulnerable the standard should
be higher. They're more likely to die just hanging around —
DR. BEAUCHAMP: That doesn't mean
they're less vulnerable, yeah.
DR. PELLEGRINO: Gil, Dr. Meilaender.
PROF. MEILAENDER: I won't ask
anything statistical, so —
DR. BEAUCHAMP: I wouldn't expect that
of you.
PROF. MEILAENDER: — so we're okay on
that.
DR. BEAUCHAMP: Maybe something Lutheran?
PROF. MEILAENDER: Not for today, I think.
We'll see what your answer is, you know, and where it takes us.
Two questions. The first is just a kind of — it may just be
a personal curiosity for me but when you were talking about the
importance of seeing the Belmont Report embedded historically in
a context where the issue was research and so forth, I mean, I don't
dispute that but I just have the feeling that there was a sub-text
that I was missing in a way. I mean, after all, there is that well-known
book "Principles of Biomedical Ethics" that has some kind
of historical relation to the Belmont Report, which —
DR. BEAUCHAMP: But nothing what people
usually think.
PROF. MEILAENDER: Well, but which
isn't confined to research ethics, right, and a somewhat similar
structure morphs out in a way to deal more broadly. So I mean, if I
was missing something, if there was something really important about
locating the Belmont Report in that historical context, I'd just
appreciate it if you could say a bit more about why you emphasized that
so much. That's the first thing.
The other sort of less just kind of personal inability to get
something, the notion of this sort of unresolvable and irreducible
tension between respect for the individual and concern for the well-being
of society, and the just sort of inability to get over that, there
would be sort of two things I'd say about that. One, you —
when you were talking about it in your talk, you used at one point,
I wrote it down, in terms of these several different principles
and some constraining others, you used the phrase "balance
and specify the moral considerations." I would have thought
that balancing and specifying are not the same thing in the way
one goes about dealing with sorting out conflicting principles.
I never — I never know what balancing means actually. I have some
sort of idea what, you know, Henry Richardson means by specification
and so forth.
So if you could illuminate the balance
metaphor a little bit, I'd like that. And the other thing is, I
don't know why we should necessarily think this tension is
irreducible and unresolvable. It depends a little bit on what you
think a person is and what you think a society is and what the relation
between the two might be. And on some views of the relation between
the person and society, there wouldn't be — the tension
needn't be left to stand. Certain views might clearly, you know,
give primacy to the claims of the individual and the well-being of the
society would just have to suffer a bit.
Other views would think of the person as
more a part of a whole, who's good had to be taken up in that. So
the tension is only unresolvable, I think, if one's just kind of
willing not to push farther on some what I admit are sort of
quasi-metaphysical kinds of questions, but if we push on those
questions, we might well get some kind of answer to it or so it seems
to me.
And I just wonder if you think I'm
mistaken about that or if I'm right but you'd just prefer not
to push on those questions or sort of how you come at that.
DR. BEAUCHAMP: Well, that's a heck of a set of
questions. It would take a lifetime to get to all of those adequately
but let me say something about it. The main point that I wish to
make about the three principles is that in order to understand those
principles and what is the meaning of those principles, it has to
be understood in the historical context. It cannot be understood
in any other way, I believe, and understand that because it's
been presented as a framework of principles. Understand that framework
of principles requires a historical understanding. Of course, you
could take respect for persons, do what a lot of people do, which
is to give it say a Kantian spin or a Kantian interpretation. This
is most certainly what the National Commission did not do. In fact,
I tried that with the National Commission. I tried to explicate
Kant and build it into the document. They said, "We don't
want that. We want plain talk so that the entire American public
understands it." So that really the larger point that I was
making is that that framework is a historical framework.
If you don't understand it in its origins, you just abstract
it out and you say, "Well, here's what respect for persons
means," and then you go and you read Ed Pellegrino and you
say, "Well, this is what beneficence means," and then
you go and read Jack Rawls or something like that about "This
is what justice means." You just won't get it. Right,
you don't understand what's going on. Moreover, there's
been a tremendous amount of confusion of the very sort that you
elude to, which is between the principles of biomedical ethics and
the principles that are present in the Belmont Report. People are
so confused then that what they've done is to interlock the
frameworks. Of course, they don't interlock, they're incoherent
actually. So those are the kind of concerns that were in the back
of my mind. I've taken a long time to sort of unravel that.
On balancing and specifying, it's a
hard question. I've struggled with this. I've argued with
Henry Richardson about it. I have argued with David DeGrazia about
it. I have argued with Jim Childers about it. It is a difficult
problem. I agree with you. I can tell you Jim Childers agrees
strongly with what you were saying but it's not easy to get out and
the reason it's not easy to get out is because you get more and
more into the theory of what happens with specification and it looks
more and more like you're balancing. That's the logic of the
problem.
In simple terms, I think of it in this
way; it think balancing occurs in judgments that are made in specific
context and it is something that we have to do and we don't have
time to specify, we don't have time to think about the consequences
and the implications of the kind of thing that goes on in
specification. We have to make judgments and we do the best that we
can to balance the different considerations that are present in that
context.
Specifying, I think of largely in a policy
context. We are able to sit back and think and figure out well, what
if this and what if that and what if the other thing and try to
articulate what the policy would be under those different
contingencies. But it's — I think it's a deep problem and I
most certainly don't think that I've resolved all the
questions.
Now, metaphysical questions; gee, I'm
really reluctant to say anything with Alfonso in the same room with
me. It might come as a surprise to you to know that most of my own
teaching career has dealt with metaphysical questions. These among
them, but many other metaphysical questions as well of the sort that
say Alfonso and I would deeply share. So I have the deepest kind of
respect for pushing in the direction of metaphysical questions. At the
same time, the most influential philosopher on me, and I don't know
on Alfonso, but the most influential philosopher on me is David Hume.
And Hume asks you to approach metaphysical questions with a certain —
a certain carefully edged skepticism and I do. I am very skeptical to
go directly to the concept that you mentioned which is a concept of
person. I'm very skeptical that that concept can be explicated,
theorized about, and presented in a way that resolve, I think, exactly
the kind of questions that you're talking about.
Now, there may be other ways to go at
those questions but I am very skeptical that metaphysics persons will
do it. That's another long paper as to, you know, what the
skepticism is and how it would be manifest, but it's the long and
the short, I think, of the answer. I don't discourage anybody ever
from engaging in metaphysical thought. Just understand that it may
have limits. It may have deep and sharp limits and not be able to get
you, especially in the area of ethics, to the conclusions that you want
to reach.
Is that okay, Alfonso, or am I making a
fool of myself?
DR.GÓMEZ-LOBO: I think the key
metaphysical issue is the issue of community rather a common good
rather than persons in Gil's question, if I understood it
correctly, right?
PROF. MEILAENDER: I would have said the
relation between the human being and the community. I mean, on a type
of person of language here, actually I should prefer human being
language, but one might find arguments suggesting — actually, we could
find some in Luther by the way, but I won't trot them out right
now, suggesting that there's a sense in which the human being
transcends the community and cannot be understood to the whole extent
of his or her being to be a part of that community. That kind of
approach might begin to suggest a certain way to resolve the tension
and not leave it unresolvable, for instance. I
mean, it's just an example, so I would have said that what I had in
mind was, yes, it is community but it is the relation between the human
being and the community and how to understand that but it does seem to
me that different ways of understanding that might lead to different
resolutions of this tension rather than just leaving it to stand
alone. That doesn't mean it will persuade everyone but I never
worried about that.
DR. PELLEGRINO: Dr. Hurlbut and then Dr.
Kass.
DR. HURLBUT: Why don't you go first?
DR. KASS: Just a couple of comments and
then a question, just sort of try again on something that was in
Gil's — part of Gil's question. I appreciate the historical
context of Belmont Principles. That's a very valuable addition to
our consideration. I also share — sympathize with your frustration
about how a careful piece of work has been misunderstood, confused by
others and abused. It's an occupational hazard.
DR. BEAUCHAMP: We all have our
sensitivities.
DR. KASS: And you can fill in the blanks
as to why I and members of this Council might have some sympathy for
that concern. We are in part responsible for the way in which we are
misunderstood and in the field of bioethics generally the Belmont
Principles, not by us primarily but by many people, have been taken,
expanded and used beyond the research context and there are also people
who try to push almost all kinds of ethical questions into the research
analogy. So — but I think — I mean, on balance, I think this is a
very valuable revisiting and clarification of what those principles are
about.
Second, I appreciate that the principles are intended not as a
licensing of a simple utilitarian approach to research with human
subjects but in fact, to introduce non-utilitarian considerations.
I appreciate that but I think part of the reason why the charge
that this is somehow in the service of utilitarian, of a utilitarian
consideration in the end, comes through the balancing — through
the metaphor of the balance. The metaphor of the balance presupposes
commensurables, presupposes some kind of measure, presupposes an
adjudication amongst competing goods, but the — you don't balance
the right against the good on the same scale if there really is
such a thing as the right.
And there are people who think that there
are certain kinds of inviolable — that there are certain kinds of
conduct that simply should not be done and cannot be balanced, this
would be an argument, cannot be balanced by certain considerations of
social good or what have you. So I guess I wonder — I wonder really
about the sort of underpinning of this notion of the need to balance
and whether that doesn't finally contribute to a view which will
eventually lean harder and harder against those kinds of restraints in
the name of the good and in which you don't sort of say no matter
how much good comes from this, this is — you're somehow traducing
something deeply important about human beings.
I didn't put that very well, Tom, but
I think you get the gist of what I'm talking about.
DR. BEAUCHAMP: Leon, you always put
things well. I think that the essence of that last part which might be
the most important part is about what I've referenced in the
language of the paper as deontological constraints.
DR. HURLBUT: Right.
DR. BEAUCHAMP: This is maybe, maybe the most important
discussion and philosophy of the 20th and 21st
Century as ethical theory unfolded. And I would be very, very reluctant
to try to say anything about how you resolve it. I do not think
it is a simple question and no one has ever convinced me that there
are clear deontological constraints that one must follow wherever
they take you irrespective of the consequences and that's where
the balancing will come back in. As the consequences are upped
and frankly, as what might be at stake under the rubric of these
deontological constraints are reduced, there may come a point where
you say, "Well, even though ordinarily it would be very wrong
to do this, in this case I think it is the right thing to do."
Now, I know these are very abstract
notions and philosophers divide heavily over this. I do think the
notion of a deontological constraint is a terribly important one and
you could probably tell that that's the way I'm representing
how I understood the National Commission as putting forward views about
justice and respect for persons as precisely as deontological
constraints. I don't know how to push harder on that without
getting deeply into Thomas Nagle's theory of this and that sort of
thing, which I don't think would be the right way for us to go.
DR. KASS: Could I just a small thought?
Let's assume that there are constraints which are not always but
for the most part, and that you might imagine yourself saying that, you
know, the rule against adultery is more or less absolute but if
it's necessary to provide an heir to Queen Elizabeth I to avoid
civil war, we make an exception, et cetera.
But would you then be thinking of what
you're doing under the metaphor of balancing? I mean, are you sort
of creating a — or is the very notion of balance a kind of
homogenization of the various considerations such that you can get them
on —
DR. BEAUCHAMP: Yes, I would think what
you're doing is balancing. The problem there is you have to
articulate some kind of an account of what it is to balance and what it
is that are the balancing considerations in these cases. Yes, I think
that's in part what you're talking about exceptive case kind of
circumstances or counter-examples or something like that and playing
that game, which I personally think is a very important game or
strategy or whatever in moral theory, I believe it inherently involves
you in balancing considerations all along the way. You can't
ultimately escape them.
PROF. GEORGE: Could I follow up very
briefly on this, just to get clear on the distinction between
specification and balancing? I can understand, we could argue it every
step of the way but I can make sense of the idea that it's
specification at work when we move, for example, from the principle of
respect for persons to the norm against direct killing of the
innocent. It also strikes me as pretty clear that what we're doing
is specifying when we move from the norm against direct killing of the
innocent to the principle of noncombatant immunity even in justified
wars.
Then if we get into a debate about exceptions to the principle
of noncombatant immunity, I can understand how that would be a debate
between people who say, "Well, you can't balance a principle
like noncombatant immunity off against other considerations,"
you know, even prevailing against a wicked enemy and so forth and
so on, and how other people would argue, no, no, there you do have
to balance. I mean, noncombatant immunity is for the most part
and usually but there comes a point at which.
But I thought that at one point you were saying that the idea of specification
itself becomes problematic, so that in moving from say — now these
are my examples, not yours obviously, from respect of persons to
no direct killing of the innocent or from no direct killing of the
innocent to noncombatant immunity, what looks like specification
does, itself, even there involve balancing.
DR. BEAUCHAMP: That's right. It may
be very hard for you to articulate — I mean, specification is
progressive specification in the way in which I believe you are
suggesting. So as you progressively specify, render the principle or
the norm more and more specific, it may be impossible to do that
without bringing balancing considerations into the focus of what
you're doing, at the very base of what you're doing.
That's what I was suggesting.
PROF. GEORGE: Okay, I mean, I understand
the position. I would want to argue against it. It would be an
interesting argument there.
DR. BEAUCHAMP: Yeah, these are hardly
settled matters.
DR. PELLEGRINO: Dr. Hurlbut?
DR. HURLBUT: Several times you mentioned
the questions and problems associated with international considerations
and I just wanted to generalize this discussion a little bit to a few
practical and theoretical problems just to get your insight from your
experience, a reflection on these kinds of problems. The Belmont
Report is, by its own admission, your writings, provides general
guiding ideals and sort of a general analytic framework for reflection
and it seems to me that at the best, that will work well within a
context where there's a certain cultural center of gravity to draw
your thinking down to consensus.
But now we're facing the strange
problem of what you might call the outsourcing of ethics, a troubling
dilemma of not just US scientists being lured overseas to do work that
is proscribed in the United States, but also the hints of corporate
commercial interest by outsourcing clinical trials and so forth. And I
think there's a really big problem brewing here and the problem is
exacerbated by our own inability to find tangible kind of structure or
skeleton to our own ethical thinking.
I know it's a vague question but
I'd just like your reflections on this. It seems to me the three
major zones where we are going to have to face up to some difficult
dilemmas and the first one is the one that's the least troubling
and the most troubling to me, it's the question of when you have a
possibility of doing a clinical study in a population that is so
wracked by disease and so under-served that you may be bringing the
only medical care they have to the community, the only supervision.
You know what I'm talking about.
DR. BEAUCHAMP: Yes.
DR. HURLBUT: So that's one thing. And especially
with regard to children, you can imagine that you could do both
a lot of good and a lot of harm in that context but then there are
the practical problems associated with competitive commercial advantages,
but overarching all of this is the more metaphysical concern with
the question of pluralism and I just would like your — I know that's
another very big set of questions but can you give us some reflections
on those concerns?
DR. BEAUCHAMP: Tell me what worries you
the most about them. Is it competitive commercial concerns or what
worries you?
DR. HURLBUT: Well, I'm not accusing
anybody of anything in saying this —
DR. BEAUCHAMP: No, I understand that.
DR. HURLBUT: — but I'm worried that
if one country has different standards for what's acceptable
practice and research ethics that they can test drugs more quickly and
more efficiently on poor human subjects, unhappy situations. There are
rumors of such things and I'm not saying they're true, but if
it's true that drugs are being tested on prisoners of in orphanages
for example, that would provide a very troubling foundation. It would
be a very efficient foundation for later testing in above board
transparent ways and it might increase the efficiency of your success
in filtering drugs, but it wouldn't be good for human dignity and
it wouldn't be good for individuals who are subjected to it.
And likewise, I can imagine situations
where scientists go places where they're allowed to do things and I
mean, we're now arguing in this country over the stem cell issue
and the 14-day limit on the use of embryos but there might very well,
I'm not saying any of our scientists want to do this, I'm not
making any accusations, but there might very well be some people
somewhere who want to use embryos later than 14 days if it could be
done and it probably can be done technically some time. So, I mean,
from a purely scientific standpoint, we would both want to know the
science of embryo genesis after 14 days, plus it might turn out to be
an efficient way to get cells, more advanced cells, tissues and organs
for therapeutic use.
So I just — I know this is a very vague
question, but it worries me a great deal that we're now becoming a
global civilization. We're gravitating toward a globally standard
material culture, but we don't seem to be able to find a moral
culture of similar — of a similar uniformity.
DR. BEAUCHAMP: I guess I think what you
are doing is rightly placing on your own shoulders a certain
responsibility for creating such a moral environment because major
public policy groups or bodies such as your own really do have that
responsibility. I think it's built into the fabric of what you
do. You started, I think, with the international domain. Let me first
say that Bob Levine is one of the most distinguished figures in the
world in international research ethics and again, I'm sort of
reluctant to move into territory where he knows so much more than I do
and he's sitting in the front row here.
But I've watched some of these things
and been to some of these places and I've come increasingly to the
view that there are a lot of American biases that — American biases,
that's not — some are American biases and some are biases that
come from institutions and so on that we should be careful about.
For example, a lot of people seem to
reflect in conversations I've had with them, the view that well, of
course the United States, we're very careful about human subjects
and we have such a great health care system that will back up anything
that goes wrong, and so on and so on. And in these other countries,
well, of course, they don't — I'm not so convinced about that,
that that's just even factually the case, that the healthcare
systems in many, many, many countries in which the research is done
quite as bad, and in fact, might be even better in some cases than the
opportunities that we can provide them in this country.
So when you go to disadvantaged
populations, there are disadvantaged populations in virtually almost
every country of the world, I wouldn't leave the United States
out. I wouldn't be so worried about say a population in China or
India or something like that thinking that somehow inherently
they're more disadvantaged than populations here. I worry about
them in all of these places and what happens.
Another bias that has disturbed me over
the years and might deserve a little bit of reflection on your part
does come through your language of competitive commercial, I believe
was the wording that you used. My own view, for what it's worth, I
just give it to you for what it's worth, is that people who come
from universities have a deep bias in thinking that, of course, their
work is completely free of bias and so on when they do research and so
on. And then there are these commercial interests where things get out
of hand. Is this sort of, should I say hubris, Leon, would that be the
right word to use in this context? It's certainly a kind of
presumption here that I've personally not found to be borne out.
I should have to tell you, I was not
raised in an academic home or environment. I was the son of a CEO of a
healthcare corporation, a non-profit one, but that was the way in which
I was raised and I came to deeply respect that culture. Now, things do
get out of control, but they also, I think, also in our academic work
and the research that we do, things can spiral out of control and we
can misuse populations and so on. So I would be careful in
understanding the context, careful in what your expectations are for
certain groups and the like, but I don't have any cosmic solutions
to these problems. They are not atypical, just a lot more complicated,
I think, than people usually think they are.
I certainly do think that your
reservations are well-taken. I guess I would just try to broaden them,
contexturalize them a little bit.
DR. HURLBUT: I certainly think that the
issue of commercial competition has its parallel at the level of
individual ambition for which academics as well as other human beings
are vulnerable.
DR. BEAUCHAMP: Exactly.
DR. HURLBUT: But still, and I wasn't
even accusing commercial interests from our country to export their
problems or outsource their ethics, I was just saying that regardless
of who the originating source is for the decisions to do research of a
certain type on — say on children, you can see how unless you — when
you dispense with ethical concerns, you can do — you probably could do
science and biomedical science particularly more quickly and
efficiently but that's — the whole point of ethics is to put into
the equation the more fundamental concern that to my mind has primacy
actually, the protection of —
DR. BEAUCHAMP: I couldn't agree with
you more. Sometimes that gets a little out of control. We think
ethics always has primacy over everything else. I'm not so
convinced that's true, but, yes, there is kind of a basic primacy
to —
DR. HURLBUT: Well, if you see ethics in a
broader context rather than just the frosting on the cake, but the very
substance of the cake itself, the thing that knits the pieces together,
the coherence of life, then it's — then it does trump everything
else because without it, you have nothing.
DR. PELLEGRINO: Dr. Foster?
DR. FOSTER: I'll be very brief, I
know we're at break time. I'm concerned about two things, Tom,
about the practical things that you've talked about. It's
certainly is clear. I've read the Belmont Report and all of those
things and I get different insights from what you've said and the
problems, you've hinted that there's sort of a loss of
understanding about many of these problems of human research.
And I should say, I've never done
human research. I mean, the most sophisticated animal I ever worked
with was you know, a mouse or a rat, you know, or something, so I
don't do this kind of research. But there is a huge increase in —
with the NIH emphasis on translational research. You're going to
see more and more human research coming along which means more and more
problems we have to say. And we don't — in the first place about
the risk; in 2004 there were 550,000 papers published in the 4,000
journals at the National Library of Medicine archives. Okay,
that's one paper a minute, okay, just to keep up with risk.
I saw something this week that in all my
life I have never seen and there are three cases in the literature of
something that's such a common disease that every physician knows
about it and it comes up, I mean, you can't predict always what
risks are going to happen even with the Internet. So people who work
on these things have a huge burden to try to comprehend — let's
say only one out of 1,000 of those papers are important, that's
still 500 major papers you have to learn about and so forth.
So there's not much time to spend on
learning more about deep ethics and so forth. I mean, I don't
understand a lot of the dialogue that goes between — you know, about
specification and all these things, you know, and I don't think
the thousands of people who are actually doing the research and the
IRBs on which they serve have the slightest inclination to study in
deep detail the sort of things that would be very important to you and
to other ethicists as a discipline which should be but in terms of just
running a clinical trial, I mean, it's not possible to do the sort
of informed consent that you have described that's ongoing,
reaching in great detail. Many times people can't understand the
simplest thing.
If you've ever tried to talk to a very sophisticated professor
of medicine and get them to take a drug that they need desperately,
like a statin or something like that, and they've read the PDR
and they've read every possible negative thing that can happen
and you can't get them to, you know, give consent to do that.
How am I going to do that to somebody who's got a grade school
education? You know, I mean, so there's the problem in — there's
a problem in carrying out this research is that there's not
an inclination or the time for either all the knowledge — I mean,
you have to try to do it. I mean, one of the things I know a lot
about is diabetes.
I can't keep up with just the papers
on diabetes mellitus, you know, that go on. So the question I want to
ask to you, isn't it sort of unreasonable to say, as we've
heard in some of these things, that we need to deepen, broaden the time
and intellectual expenses in trying to do things more perfectly and
more in accord with what the wonderful report Belmont meant? I mean,
is that really possible? I can tell you very frankly as a chairman of
medicine who deals with people who do all these things all the time, I
think that's absolutely impossible and unrealistic and one of the
thrusts we heard yesterday, we need to try to diminish the safeguards
that are coming up with the IRBs in order to get a better assessment of
what the true problems are. That's — and I don't want you to
answer much about that except — because the time is up, but that's
what really worries me. It's in seeing people who are actually
doing all these things and on occasion you get heinous mistakes and
some of them are deliberate, you know, that people have done wrong
things but I don't know how — I don't think we're going to
have a discussion in IRBs like we've had here this morning. I just
don't think there's a chance in the world that that will
happen.
DR. BEAUCHAMP: Dan, I don't have much
to say about that. I agree with you wholly and completely. You are a
— you're still a Donald Seldon Professor of Medicine; is that
right?
DR. FOSTER: Sixteen years and I've
passed that on.
DR. BEAUCHAMP: You've passed that on,
okay. Well, let me say there are only a few Donald Seldons. Donald
Seldon, for those of you who don't know him, is one of the great
Professors of Medicine of our time, Dan's predecessor and he has
the capacity to consume all of this literature and process it, but he
is just about the only person I have ever known in my life who can do
so. I agree with you wholly and completely, and therefore, the system
has to find some accommodations and it has to be streamlined in certain
ways.
One of the things that we looked at when I
was on the Institute of Medicine Committee looking at responsible
research, was how do you take what is clearly a broken backed system,
the IRB system, and try to reduce the workload to straighten it out so
it can do its work properly. That in itself is just a huge, huge chore
and so what you've got here is you very nicely lay out the tip of
an iceberg that we have to deal with.
DR. PELLEGRINO: Dr. George.
DR.GÓMEZ-LOBO: Can I make a — sorry,
thank you. Just a quick remark, but isn't that precisely the
reason to have something like distribution of labor?
DR. BEAUCHAMP: Absolutely, absolutely.
DR.GÓMEZ-LOBO: Because of course, the
clinical physician, of course, can't do all of this but there has
to be someone thinking through these problems it seems to me.
DR. BEAUCHAMP: No, no, let me give you an
example. One of the things that we talk about a lot at the Institute
of Medicine was the problem of conflict of interest by contrast to the
work of IRBs. Quite a few institutions throw several kinds of conflict
of interest onto the IRB. The IRB should not deal with conflict of
interest. That should all be handled, done and over with before they
even begin to process things. In other words, you should have a
separate conflict of interest committee.
Now, I personally think that conflict of
interest is a deeply under-analyzed notion not well attended to
particularly non-potential conflicts of interest. That, then becomes
itself — can become itself a major preoccupation. Most certainly IRBs
in my view should be shielded from it. So yeah, of course, I'm
going to agree with you.
DR. PELLEGRINO: Dr. George?
PROF. GEORGE: Yes, I've been —
DR. PELLEGRINO: Last comment.
PROF. GEORGE: Yeah, and thank you for the
third opportunity. Sorry to take us beyond the limit but just I'll
try to do this quickly because Dr. Beauchamp's comments as I've
been reflecting on them brought a question to my mind about how we
think about the common good and how we think about what you've been
referring to as deontological constraints.
In professional bioethics, I think a lot
of people conceive of the common good or social benefit in utilitarian
terms. So they think that there's a common good and they've
got a conception of the common good and that conception is a
utilitarian conception. Now, for bioethicists for whom that is just
part of a larger or more comprehensive utilitarian approach to ethics
and to life, that's the end of the story. But there are other
people in professional bioethics who aren't satisfied with the
utilitarian story as a comprehensive approach to ethics and, therefore,
they see a need for constraints on thinking of things in utilitarian
terms and ordinarily those constraints are matters of protecting
individuals who could be sacrificed in a way that would be unethical
for the sake of the common good where the common good is conceived in
utilitarian terms and where they're prepared to conceive the common
good in utilitarian terms.
And then you have a debate between
utilitarians and non-utilitarians. But of course, there are
alternatives to thinking of the common good in utilitarian terms. I
mean, there could be, for example, a purely deontological theory. I
think it would be problematic. There's no doubt about that, it
would be problematic but there could be such a way to try to solve the
problem that you've identified as the problem that nobody has
solved and probably nobody will solve, thinking about individual
interests and the common good.
But in addition to that option, there is
the kind of conception of the common good, I would say a
non-utilitarian conception of the common good, that's part of a
longer tradition, you know, going well back before the great founders
of utilitarianism, and which still has very articulate exponents today,
I mean, some in this room like Gil and Leon and Alfonso. I mean, the
way their thinking and I, myself, try to think about the common good is
to begin with a non-utilitarian conception of it and on such a
conception, rightly or wrongly, there may be all sorts of problems with
this, but on that sort of conception, what you are talking about and
what a lot of professional bioethicists talk about in terms of
deontological constraints on the pursuit of the common good, are really
conceived as aspects of the common good. So there's not a
contrasting of individual interests or rights with the common good, so
we would never think with Ronald Dworkin in terms of rights being
trumps on the pursuit of the common good conceived in utilitarian
terms.
But rather we would see those individual interests, there's...
one might even say individual rights, as aspects of the common good
itself. So that there's an attempt, at least at seeing individual
interests and the social good in more of a harmony and when we would
restrain ourselves from certain courses of action that might otherwise
be regarded as ways of advancing the common good, we wouldn't
be, even on our own understanding, sacrificing the common good for
the sake of deontological constraints or the individual or individual
rights. We would be pursuing the common good, because the common
good itself included a concern for the dignity and worth and rights
and welfare of the individual.
DR. BEAUCHAMP: I think I agree with you
completely. Let me only add that sometimes you find your situation is
one of strange bedfellows. And it should come as no surprise here, I
believe, that that's so. My own greatest teacher in philosophy,
including in matters of this sort was David Hume and Hume's
fundamental commitment was to the common good. But the moral theory
doesn't really turn on the common good. The moral theory unlike
what many people have said about him turns actually on the theory of
the virtues. And so what's buttressing and supporting the
over-arching view of what is in the common good is that ethics
originates only in the bosom of a conception of common good as fostered
in a society is the importance of virtue.
Now, the funny thing there is so many people have interpreted
Hume as a utilitarian. I personally think that's a difficult
interpretation to get out of him, but what you're saying could
easily be explicated along the lines of Hume's view. What you're
saying could easily also be explicated along the lines of John Stuart
Mill's view in many ways. One possible way to understand Mill
is his doing exactly what you just laid out. Now what a lot of
people want to say, "Oh, yes, but he contradicts himself along
the way. He screws up."
Well, maybe he did. Maybe he did, but I
think he has in his philosophy in mind exactly the objectives that you
have in mind and by the way, sometimes when I hear Edmund talk about
beneficence and the common good, it sounds an awful lot like Mill to
me, talk about strange bedfellows. But that's at any rate — I
mean, we need to frame these things in terms of what people really held
and what these frameworks are in a broad way committed to.
PROF. GEORGE: Yeah, I take your point actually
about Mill. I remember reading years ago when I was doing my own
doctoral work, a very interesting book by John Gray, one of John
Gray's early works trying to harmonize the Mill of "On
Liberty" with the Mill of "Utilitarianism."
DR. BEAUCHAMP: Yeah, that's exactly
what you have to do, yes.
PROF. GEORGE: Yeah, and I thought it was
actually a persuasive case.
DR. PELLEGRINO: Thank you very much, Tom,
and the commentators. We're a little bit overtime so that
we'll have our break and return at 10:30.
(A brief recess was taken at 10:12 a.m.)
(On the record at 10:35 a.m.)
SESSION 6: CHILDREN AND CLINICAL RESEARCH
DR. PELLEGRINO: This session, this last
session of the morning, will be a little bit different. This is the
first time we're trying something of this order and we'll
invite your participation. I'm speaking to the members of the
Council. In fact, the emphasis will be on your continued
participation. I'm very pleased with the way the Council has taken
part in every discussion and we fill every moment of time with their
discussion, which I think is crucial and important and relevant.
But we've asked Dr. Bob Levine to
present a case, maybe our clinical colors are beginning to show but I
think you may find this a very interesting way to look at some of the
problems we've been cogitating over the last several days in a
particular circumstance. And while bioethical issues must rise above
individual's general perceptions and concepts, nonetheless, they
come back to individuals and this is the final point. It's really
the moment of truth to see how a principle or a rule or a policy
effects the person who is ill or the person who is a subject, how it
effects individual human beings.
Forgive me for that interest as a
clinician. I hope you'll find that it is not irrelevant to the
larger issues we've been discussing.
So Bob is going to present a case and then he's going to involve
the Council members and then make some comments and if I can restrain
myself, I will not make too many, but I probably will make a footnote
here and there. I've been practicing restraint in the interests
of maintaining a little bit of neutrality. Bob.
DR. LEVINE: Thank you very much, Ed. Here I
am again. I thought the first half of this morning was a very interesting
and important discussion and when Tom Beauchamp said that he and
I speak as if with one voice, I thought, "Don't I wish?"
The case that you have in front of you, Ed has asked me to just
go through it, not read the whole case to you but go through it
to pick up on some of the important points and then to turn this
over to you for discussion.
This is a case that was published in the IRB Journal about 15
or so years ago. In the publication, which is footnoted at the
end of the second page, in case you want to read the full case,
there's a careful analysis of the ethical issues. When I recommended
this case to Dan Davis, he decided to use it and I want to congratulate
Dan and Ginger Gruters for a very skillful job of restoring this
case to its original position, that is in the form that it was presented
to the IRB rather than after the IRB did its work and wrote its
interesting ethical analysis. So I congratulate and thank them.
I think one of the interesting things
about presenting a case is that some of you are clinical scientists who
probably have complained about all of the things the IRB has asked you
to be responsive to. It's my experience, though, that when we all
get together and review a case as if we were an IRB, you will find
emerging from your respected colleagues some of the things you've
been complaining about that the IRB was doing.
Without further ado, I will get into this. The study is a proposal
to investigation mechanisms of diabetic instability in children.
The study uses techniques that are very well-tested and have been
used extensively and safely, but in adults. The study requires
— well, first, it's necessary to look at young people. Yes,
sir.
DR.GÓMEZ-LOBO: Could you define diabetic
instability for the lay person?
DR. LEVINE: I don't dare with you
sitting next to Dr. Foster.
DR. FOSTER: It's difficulty in
controlling the blood sugar.
DR. LEVINE: Thank you. They want to look
at very young subjects. They want to see if there are any changes that
are related to the changes at puberty. So it's important for them
to look at children from the age of about eight until about the age of
18. This is quite a span. The studies will involve diabetic children,
children with unstable diabetes, insulin dependent diabetes and it will
also involve their siblings. Siblings are designed to give them normal
control information.
They justify involving the siblings
because according to the regulations, if you want to do studies of this
sort, you must be developing information that's responsive to the
condition or disorder that the child subjects have. And they define
the condition or disorder as being situated genetically as having about
a 25 percent risk of developing diabetes themselves. This
distinguishes them from the mainstream of normal children.
They recognize that this is a compromise,
that siblings who are somehow genetically pre-disposed to develop
diabetes might have some abnormalities of glucose metabolism but they
felt this was the best they could do. The studies involve a 48-hour
admission to the hospital for each child. The first day they will have
a 24-hour profile of blood hormone levels and this requires the
insertion of an intravenous cannula, a small plastic tube put in their
vein and then they can periodically attach a syringe to that tube and
pull back a little bit of blood.
On the second day, they plan a four-hour
hormone sensitivity test. For the clinicians here, the test is called
a glucose clamp or a hyperglycemic clamp procedure. The procedure will
require that the child be immobilized in bed for four hours with his or
her arm on a board, tap
