WORKSHEET:
BIOETHICS
INTRODUCTION
Ethics and science share a commitment to
rational thinking. The scientific method is a form of
rational inquiry into FACTS. Where they differ is in the criteria used
to judge these facts. The
scientific method uses a very specific set of rules and procedures as
“proof’ of a fact. Ethics is a
rational inquiry into what is right and what is wrong for a specific action
or belief. In this worksheet
we will use two different techniques to study bioethical topics. All work
will be accomplished by a
group of 3-5 students and only 1 answer sheet must be completed for each
group (Remember to put
everyone’s name on the finished answer sheet.
PART I: MAKING CLAIMS
Bioethical decisions are difficult because
they often require specialized knowledge about a new
procedure or technology. The bioethical issue used in this part of the
worksheet is called “Medical
Decisions” and is centered on the process of organ transplantation.
The information given is not
“all-inclusive” and some extrapolation of facts will have
to be accepted. Read the background
information for Medical Decisions, and apply it to the following question.
What claims can you make
for “FACT”, for “VALUE”, and for “POLICY”
?
A: Claim of Fact
This is supported by facts or data such
as statistics, graphs and research findings from reliable
and reputable sources which the audience can accept, An example of this
type of claim is "Capital
punishment is not a deterrent to crime."
To defend a factual claim you
should:
- Be sure that what you are trying to prove
is clearly stated from the beginning.
- All terms that might be controversial
or ambiguous (i.e. "surrogate mother) should be
defined at
the start.
- Data is sufficient, accurate, recent and
from reliable sources. An authority with
credentials
from Harvard University who published an article in Scientific
American will
have higher credibility with an audience (and your teacher)
than a citation
from an article in the National Enquirer.
B: Claim of Value
This attempts to prove that some things
are more or less desirable than others based on
standards of taste and morality. Claims of value express approval or disapproval,
and require
the audience to make a judgment. Advertisements are common sources of
value claims, but
value claims emerge whenever people argue about what is good or bad, beautiful
or ugly. An
example of this type of claim is, "Using animals for research is
wrong."
To defend a claim, of value
you should:
- Prove the values or principles to be more
important than the end result.
- Use examples and illustrations to clarify
meanings and make distinctions.
- Use the testimony of experts to prove
that knowledgeable or highly regarded people
share these
values.
C: Claim of Policy
This asserts that specific policies should
be instituted as solutions to problems. The expressions
"should, must or ought to" are usually used. An example of this
type of claim might be, "Using
microorganisms for biological warfare must be stopped."
To defend a claim of policy
you should:
- Make your proposal for change clear, establishing
the distinct benefits gained by
adopting
your proposal.
- Support your proposal with solid data,
moral considerations and common-sense reasons.
Here is a SAMPLE of the kind of thinking involved
in this part of the worksheet.
Topic: Genetic Screening
Claim of Fact à Genetic screening is not a reliable predictor of
disease.
Claim of Value à Results of genetic screening should be private.
Claim of Policy à Insurance companies should be permitted to require
genetic screening.
Below is the topic called “Medical
Decisions”. Use it to complete the accompanying Answer Sheet.
Some of the information is factual and some is inferred for purposes of
this worksheet. The group
should read the topic and then discuss it before completing the Answer
Sheet. If everybody cannot
agree on an answer, then a simple MAJORITY decides what will be entered
in the Answer Sheet.
*****************************************************************************************
SITUATION: The following 3 people need liver transplants
to live.
All 3 are in critical condition and will
die within 24 - 48 hours without a transplant.
Only I donor liver arrives each week, and
one should arrive today.
Who should receive this liver, and why?
Here is some background information about
each of the people needing
the transplant.
Mike: is a 27 year old mechanic
is married with 2 young children
is healthy in every other way except his liver
is a recovering alcoholic (been clean for I year)
Mary: is a 6 year old child
is the 5th child of an unemployed mother (last 3 years on welfare)
has infantile diabetes
family has no insurance (depends on Medicaid)
John: is a 45 year old businessman
is President and owner of a major corporation with 28,000 workers
has been happily married for 25 years, with I child still in
junior high school, I child in high school, and I child in college.
is too busy to exercise, thus is 50% overweight
has insurance that will pay ALL expenses
You are
the doctor, and you are talking to the 2 individuals and their families
that will NOT be receiving the liver transplant. Explain the advantages
and disadvantages of the following options.
1: Try an experimental procedure in which fetal liver cells are
implanted in your liver.
Success rate = 10%
Recovery time = 3 months
Other considerations: Fetal cells will have to come from human fetuses.
2: Try a new experimental drug who's effectiveness is unknown (you
will be among the first group of humans to be tested)
Success rate = unknown
Recovery time = estimated 1-2 weeks
Other considerations: One possible side effect is sterility (occurred
in 25% of animals tested)
3: Transfer to another hospital.
Other considerations: Whenever a transplant patient transfers to
another hospital they must begin at the bottom of the organ transplant
list again.
4: Try a new artificial liver machine.
Success rate = estimated at 20%
Recovery rate = never recover, but can keep you alive up to 6 months
Other considerations: The liver machine is large and bulky, thus
the patient is kept in the same bed in the same room throughout
the use of the machine.
5: Donating your good organs to others in need, or donating your
body to medicine.

PART II: RISK/BENEFIT ANALYSIS
Those who study ethics have identified
three guiding principles as the foundation for ethical
decision making;
1. Beneficence
The principle of beneficence states that
we should promote good for others and avoid harm to them.
This principle can be applied to whole groups of people as well as individuals.
The application of this
principle in bioethical decision making requires us to ask: will our decision
result in a greater balance of
good over harm? For example, critics of the Human Genome Sequencing Project
have raised several
questions requiring the application of the beneficence principle. These
questions include: Whose genes
will be sequenced? Will this project result in any human suffering? Will
there be a greater good for all
as a result of this project? Can the information resulting from the genome
project be used against people?
2. Respect for Autonomy
The core of this principle is the intrinsic
value of the individual. Each person has fundamental self
worth and dignity which should be respected by others, even if they hold
different values. ln addition,
individuals should have freedom to control their lives. Using the Human
Genome Project as an example,
questions that require consideration of this principle. Will the information
gained from this
project have an impact on the freedom of individuals to determine career
choices? How will the
information be used by health care professionals in determining treatment?
Will there be any limits on
personal decision making?
3. Justice
There are three ways to approach the principle
of justice. The first is that everyone has an equal
right to basic needs - food, shelter, clothing, health care, education,
employment The second is that
some individuals have earned the right to special treatment based on their
merit A third approach is to
treat everyone equally regardless of perceived merit When applying the
principle of Justice one can
either look at the outcomes of a decision or consider the process leading
to the outcome while remaining
neutral as regards the outcome itself. Questions about the Human Genome
Project which can be
considered using this principle are: What is the most equitable way to
distribute the funds earmarked
for scientific research? On the basis of contribution to society? Merit?
Best use of resources?
If values are going to be included and discussed in the classroom, teachers
and students should
have a basic understanding of the principles of ethics. Otherwise debates
and discussions become
“free-for-alls" leaving students with the conclusion that the
issues are irresolvable and that only
experts (an make decisions.
In this part of the worksheet
you will look at specific scenarios of people in situations that require
a bioethical decision. Using risk/benefit analysis as a critical thinking
tool, students try to come to a
decision as a group and as individuals. Risk/benefitting is only one means
of addressing moral issues.
One would hope that ethical decisions are based on more than R/B analysis.
However, this method
facilitates initial considerations of ethical/moral problems. It involves
brainstorming, literature search,
small and large group discussion, recognition and weighing facts and opinions,
and decision-making skills
related to current bioethical issues.
Use following the procedure to complete
Part II of the Answer Sheet.
1. Read all of the scenarios involving bioethical dilemmas
2. As a group decide which dilemma you wish to discuss, and use to fill
in the Answer Sheet.
3. Take time to share information or ideas about the issue with the whole
group (i.e. brainstorm).
4. Fill in the Risk/Benefit Analysis Sheet (Part II on the Answer Sheet)
as you discuss the different
ideas. Use this information as a basis
for later portions of the Analysis. Be sure to discuss the
difference between a fact and an opinion.
Remember: If disagreements occur, the majority decision
is written on the Answer Sheet.
5. When done everyone in the group should be prepared to share their decisions
and points of views with
the rest of the class.
Below are 4 bioethical scenarios
to be discussed, to be used to complete the accompanying Answer
Sheet. All of the scenarios are factual, but many have similar “real-life”
cases. The entire group
should choose one of the scenarios and then discuss it fully before completing
the Answer Sheet.
************************************************************************************
1. James, a recent graduate from a mid-western teachers' college was excited
about his new job as a
biology teacher. However, one week prior
to the opening of school, James was notified by the school
board that he would not be offered employment
due to the fact that he tested positive for the
existence of a gene for Huntington's Disease.
According to the school board chairperson, their
decision was based on the fact that James
would eventually cost the school system hundreds of
thousands of dollars in health benefits.
Should James' individual rights be protected? Should he be
given employment? Did the school board
act within the boundaries of law?
2. Recently a couple conceived a child in hopes the baby's
bone marrow cells could save the life of a
teenage daughter who is dying of leukemia.
The dying girl needed a bone marrow match and that is
most likely among siblings. It was predetermined
by the couple that if the bone marrow matched it
would be removed from the baby by a surgical
process as soon as medically possible, which is
approximately 2 years old. Is it right
to conceive one person to serve the needs of another? Can
parents distribute one child's bodily parts
to save another child? Does one have a right to
"Grow-his-own-spare-parts"?
3. A fireman has a positive pre-symptomatic test for Huntington's
Disease (HD). He has not told his
employer because he fears he will be fired.
He has only a few more years to go before he can retire
comfortably with 20 years on the force.
Meanwhile, he worries that he is already in the early stages
of the disease, because he is starting
to make errors in judgment The last time he went out to a fire,
the chief told him to pull the truck forward.
Instead he put it in reverse.
4. Mr. Hodges has Huntington's Disease (HD). Since he
has been unable to work for the last three years,
he, his wife and their three teenage children
have been on government-assisted welfare programs
for more than two years. As his disease
progresses, Mr. Hodges is very likely to be institutionalized
in the near future. It is estimated that
the Hodges family will cost the government $150,000.
Because society must take responsibility
for the Hodges family, should screening be compulsory for
the children? If they are tested, would
you require full disclosure of all information but no further
government interference or should prenatal
testing be mandatory when the teenagers become
pregnant? Would you favor discontinuing
government aid if affected individuals chose to have
children even after they have received
complete information regarding the potential genetic risks?
