As a starting point for understanding
the ethical complexity of medical research conducted on vulnerable subjects,
bioethicists point to Nazi-era Germany, where Josef Mengele, the notorious
"Angel of Death" of the Third Reich, oversaw an attempt to cure existing and
persistent German diseases and to fulfill the Nazi dream of creating a perfected
Aryan race.
In doing so, Mengele and his
professional peers embarked on a series of gruesome, brutal and deadly
experiments on their captive laboratory subjects.
American judges presiding over the
trial of many of these Nazi doctors in 1947 convicted 23 Nazi doctors,
sentencing seven to death. (Mengele himself escaped to South America, where he
died in 1979.) Yet the barbarity of the experiments seemed to warrant a more
far-reaching response. In The Nuremberg Code of 1947, it was declared that
experimentation on human beings had to be conducted in such a way as to avoid
all unnecessary suffering; that it had to be performed toward the good of the
society, "unprocurable by other means;" and perhaps most significantly, that
such experimentation was never acceptable when subjects did not or could not
freely consent.
"The voluntary consent of the human
subject is absolutely essential," reads The Nuremberg Code. "This means that the
person involved should have legal capacity to give consent; should be so
situated as to be able to exercise free power of choice, without the
intervention of any element of force, fraud, deceit, duress, over-reaching or
other ulterior form of constraint or coercion."
In an attempt to deflect condemnation
of their own practices, Nazi doctors facing death sentences pointed toward
American experimentation on prisoners ongoing since the beginning of the 20th
century with little success. Sentences and executions meted out, American
doctors condemned the horrors of Nazi medical experimentation, even as they
disassociated themselves from the ethical implications of the trial and the
code. Without any significant opposition to speak of, all manner of research
studies on unsuspecting American citizens, army recruits and the mentally
disabled took off in the aftermath of the Holocaust.
Medical research using prisoners in
particular flourished amidst a three-decade fiesta of federal, pharmaceutical
and cosmetic company funding, leading the presidents 1994 advisory committee on
federally-funded radiation experiments to note that, following World War II, the
U.S. was the only nation in the world officially continuing to use prisoners in
experimental clinical trials. But revelations about the Tuskegee Syphilis study
and the publication of Jessica Mitfords Kind and Usual Punishment about the
conditions of imprisonment in the early 1970s put a gradual end to prison
experimentation as well as many other forms of unethical research.
Responding to the apparent need for
stiffer regulation in the realm of human experimentation, the government
convened of a special commission to investigate the protection of human subjects
of research. After the subsequent publication of the Belmont Report in 1979,
state and federal guidelines regarding research on prisoners took on a more
carefully crafted tone; the onus was now placed more directly on researchers to
assure informed consent and to prove the merit of any studies conducted on
captive, illiterate, uneducated, mentally incompetent or disabled subjects.
As a direct result of the Belmont
Report, seventeen federal agencies adopted the "Common Rule," which prohibits,
with limited exceptions, nonconsensual use of people in medical research and
which requires reviews of proposed studies by institutional review boards. Most
prison research withered and died out, extinguished by the dual flames of public
outrage and the watchful eye of federal and university-based regulators, until
the dawn of a worldwide HIV epidemic by the late 1980s and an accompanying,
insidiously prevalent epidemic of hepatitis C within U.S. prisons revitalized
medical interest in this kind of research.
Research in prisons represents only a
fraction of the medical studies conducted on human subjects in the U.S. each
year, however, and problems inherent to such research are apparently widespread.
At a Medical Research Summit held in Washington, D.C., in late March, more than
200 researchers, medical ethicists and administrators gathered to discuss those
problems, stressing the need for full disclosure to patients of the financial
ties that researchers might have to their clinical trials, raising question
about federal oversight of clinical trials and other research studies.
But change is likely to be slow in
coming, as medical research is enjoying a time of heavy pharmaceutical funding
and federal government support. Medical centers at leading universities across
the nation are still mainly supported by federal dollars. The University of
Miami Medical Center, for instance, is one of the largest research facilities in
the world with $191 million in research funding, and one of the top universities
in expenditure of federal funds for research and development, with more than
1,000 ongoing research studies. The Department of Health and Human Services
(HHS) is the Yale School of Medicines principle funding source, with $178.7
million (or 67 percent of total funds granted in fiscal year 1998) coming from
HHS and its agencies.
In addition to the funding received
by federal agencies and pharmaceutical companies, researchers engaged in
research involving prisoners also appear to be cost-benefiting from the fact
that they conduct much of their research in prison medical wards, utilizing
prison resources, transportation service, facilities and possibly even the labor
of prison employees. According to Dr. Thomas of the Florida Department of
Corrections (DOC), neither the institution nor its inmates receive payment for
their assistance or participation in clinical trials.
The Roche drug company-produced
newsletter, Positive Populations, mentioned the Florida DOC arrangement with
University of Miami researchers by stating that "[t]he DOC ... has been a
willing and enthusiastic partner, putting in place policies and procedures to
eliminate barriers and give [the researcher] and her staff access to inmates,"
including the busing of some inmates to a central prison reception center for
research.
