International research ethics : some issues
What
are the odds of a poor Guatemalan getting entry into a trial for the latest AIDS
drug cocktail - and of continuing those drugs once the trial is over? Can a
placebo control be used where the local standard of care does not include a
proven treatment? Does the answer differ depending on whether the study is
collaborative or locally funded?
This article identifies and discusses some
ethical issues in international research. Research collaboration with developing
countries is plagued by differing interpretations of ethical standards and by
inequitable funding. Only 10 per cent of global research funding goes to
diseases comprising 90 per cent of the global burden. Collaborative research can
exacerbate the poor state of local research environments by diverting local
scientific expertise from more important to less important areas of research,
and neglecting national research networks.
The awareness that the success of
research collaboration should not be judged solely on the results of scientific
research activities must be coupled with a learning approach to craft a
sustainable, mutually beneficial working relationship that, aside from advancing
science, must address inequity and put local priorities first, develop capacity
with a long term perspective, and preserve the dignity of the local people by
ensuring that the benefits of research will truly uplift their
status.

Revising the Declaration of Helsinki : one opinion
Should the
control group of a research study in a poor country receive the best possible
treatment or the standard of care - which might be nothing at all? Two articles
in the New England Journal of Medicine debate the question. The first author
states that the proposed revisions of the Declaration of Helsinki may
"inappropriately cause a shift to an efficiency-based standard for research
involving human subjects and weaken the principles of the investigator's moral
commitment to the research subject and the just allocation of the benefits and
burdens of research. The revisions will also logically lead to an explosion of
research in developing countries that would be intended mainly to benefit
developed countries another affront to current notions of ethical
research."
The proposed changes are subtle. They would allow a waiver of
written informed consent if the ethics committee determined that the risks posed
by the research are slight or if the procedures to be used in the research are
customarily used in medical practice without informed consent. It does not
insist on consent being obtained by a physician who has no conflicts of
interest. And it will permit the control group to receive "the local standard of
care", which could be no care at all. Finally, it dilutes the prohibition
against publishing unethical research.

the Declaration of Helsinki will they weaken the ethical principles underlying

..and another opinion
The second author argues that
the Declaration of Helsinki makes a spurious distinction between therapeutic and
non-therapeutic research, resulting in errors not intended by the authors.
Second, it includes several provisions out of touch with contemporary ethical
thinking. As a consequence, many researchers routinely violate its requirements.
Such routine violations and their associated attitudes rob the
declaration of
its credibility.
For example, insistence on active controls would increase
expense, decrease efficiency and actually violate international ethical
guidelines which require that research is responsive to the health needs and the
priorities of the community in which it is carried out. Referring to the
placebo-controlled trials of short- course AZT to prevent maternal-foetal
transmission in developing countries, the author argues that the placebo control
meets ethical requirements: what people in developing countries need to know is
whether the short- course regimen is better or worse than that which is
currently available.
Countries which cannot afford all the treatments
available to residents of industrialised nations must be allowed to develop
affordable preventive and curative interventions. Research sponsors in
industrialised countries should not be prevented from assisting developing
countries in their efforts. The Declaration of Helsinki should be revised to
reflect this understanding.

Standards for mandatory programmes
Mandatory public
health programmes are justified in limiting the rights of individuals because
they benefit the community as a whole. The authors suggest that any mandatory
programme should meet certain requirements: failure to implement it would
negatively affect the rights of others it is the least restrictive feasible
alternative, and it is fairly and equitably administered. They evaluate 10 TB
programmes in the US using mandatory Directly Observed Therapy (DOT) to see if
they fulfilled these criteria. Their findings: "DOTS was not shown to be
consistently more effective than ... a high-quality self-administered treatment
program. Within DOT programs, the least restrictive alternative was not
consistently used (as demonstrated by variations in frequency, duration, and
location of treatment), nor was DOT always applied equitably."

Conflict of interest: some findings
In an editorial in
the issue of BMJ containing a collection of material on conflict of interest,
the author notes the accumulation of evidence that financial benefit makes
doctors more likely to refer patients for tests, operations, or hospital
admission, or to ask that drugs be stocked by a hospital pharmacy. Reviews
acknowledging sponsorship by the pharmaceutical or tobacco industry are more
likely to draw conclusions favourable to the industry.
The author refers to
two significant papers documenting the consequences of conflict of interest. A
study of 70 journal articles on calcium channel antagonists for treating
cardiovascular disorders showed that authors were more likely to support the
drug if they had a financial relationship with a manufacturer. Two thirds of the
authors had financial relationships with manufacturers, but "only two of the 70
articles ... disclosed the authors' potential conflicts of interest." As many as
96% of the supportive authors had financial relationships with manufacturers,
compared with 60% of neutral authors and 37% of critical authors.
Second, of
106 review articles on passive smoking looking at characteristics determining
their conclusions, 37% concluded that passive smoking was not harmful and the
rest that it was. A multiple regression analysis controlling for article
quality, peer review status, article topic, and year of publication found that
the only factor associated with the review's conclusion was whether the author
was affiliated with the tobacco industry. Only 23% disclosed the sources of
funding for research.

Medicine and human rights
1999 marks the 50th
anniversary of the 1949 Geneva Convention and the 100th anniversary of the Hague
Convention, and follows by one year the 50th anniversary of the Universal
Declaration of Human Rights. These anniversaries offer the BMJ the opportunity
to explore a number of ethical and policy dilemmas that face medicine and
science when issues of moral choice arise in war and in peace.
Discussions
through case example, historical analysis, analysis of clinical data, or
assessment of current and anticipated issues, seek to illuminate the relevance
of key points in international humanitarian law and human rights to those whose
work is guided by the more familiar principles of medical and research
ethics.
It is hoped that readers deliberating on these questions of medicine,
moral choice, and international law will appreciate that in the sphere of
international humanitarian law and human rights there is not only room for the
moral voice of physicians but an outright imperative that it should be
heard.

Applying guidelines rationing health care
In 1997, a
63-year-old Maori man with moderate dementia was taken off dialysis for end
stage renal disease, applying a New Zealand health service guideline that
'moderate to severe dementia' is a factor 'likely to determine that an
individual is not suitable for treatment.' since there must be ability to
co-operate with active treatment.' He died after an unsuccessful effort to get
the Human Rights Commission to review the decision. The commission ruled that
the guidelines were legitimate and used correctly. The case has been described
as "discrimination leading to death." This essay notes that the questions raised
by this decision are central to the concerns of people with disabilities: "It
would be thought unacceptable to withhold dialysis from patient who are blind or
have an intellectual disability, yet the rationale underpinning the 'mental
function' guideline applied to Mr Williams - 'there must be ability to comply
with active treatment' - could also be applied to such
patients."

Defining limits
What does the researcher do when the
group that s/he wishes to study is incapable of giving informed consent? Not
doing research would deny that particular part of the population the benefits of
research-dependent care. The author discusses the limits to research and
therapeutic intervention on perinatal patients.
Starting with a discussion on
therapeutic innovation, the prelude to systematic research, he goes on to
consider consent in therapeutic and non-therapeutic research. The problems with
accepting parental consent for non-therapeutic research are pointed out. The
author presents guidelines for designing research involving perinatal subjects:
it should be worthwhile and the goals realisable; and it should involve only
"minimal risk to the research subject", a subject which is defined in some
detail.
Regarding limits to therapeutic interventions, the decisive factor is
the interest of the patient. However, when a clinician is eager to evaluate a
new technique and a parent is faced with losing a child, the cost to the child
in need may get overlooked. The author concludes by referring to a four-year-
old child who spent "the last months of her life undergoing harrowing heroic
procedures. This raised the question of whether some paediatricians felt there
was no point at which to call a halt to innovative practice."

Deaf-mute or brain dead?
The author, a nephrologist,
comments on the public response to the report of Prakash, a mentally disabled
deaf-mute man, whose kidney was transplanted into his brother who had renal
failure (see IME VII f2]: 38 VII [3]: 70). The consent form was signed by the
man's mother. The author writes: "Had the guardian a right to give consent to
the surgery? This boy was treated like an animal, not like a human being with
some rights. He was subjected to the risk of death, albeit very small, and to
considerable pain..." Some letter writers made surprising observations. One
wrote that the transplant would "fill the hollowness in (Prakash's) heart and
unknowingly or knowingly add a new meaning to his silent existence." Another,
the president of the Indian Society of Organ Transplantation, declared that
Prakash was "suffering from brain death due to loss of his higher sensory
faculties " and in any case, if he were a "sane man, (he) would have been most
happy to donate a kidney to his own brother." The author notes, "Almost half the
perfectly sane, prospective, related donors decide that they do not wish to
donate a kidney to their brother or sister, son or daughter. ...If we throw
ethics to the wind, where will it end? Our mental health institutions are full
of mentally incompetent people. Why not take their kidneys, and maybe lungs,
hearts and liver as well, and thereby give some meaning to their lives?"

Love and medical ethics
The March 1999 issue of the
Eubios journal contains papers from one of the sessions at the TRT4 in October
1998, looking at bioethics and the love of life. A number of the articles
discuss the relation of love and medical ethics: as a general concept as well as
in specific cultures such as the Philippines, south Asia, India, Iran, Thailand
and China. Of the many valuable essays, one of them is particularly useful. The
author discusses the question of bioethics and the love of life through the five
central questions for bioethical theories: the meta-ethic, the normative
questions of what is value, what is virtue, what are the principles of right
conduct; and the relation between principles and causes.
