People Should Have the Right to Control Whats Done With Their Tissues
Stored homo tissue: an ethical perspective on the fate of anonymous, archival textile
Abstract
The furore over the retentivity of organs at postmortem examination, without adequate consent, has led to a reassessment of the justification for, and circumstances surrounding, the retentiveness of whatever human material later postmortem examinations and operations. This brings into focus the big amount of human material stored in various archives and museums, much of which is not identifiable and was accumulated many years ago, under unknown circumstances. Such anonymous archival textile could be disposed of, used for teaching, used for inquiry, or remain in storage. Nosotros debate that there are no ethical grounds for disposing of the fabric, or for storing information technology in the absenteeism of a didactics or research rationale. Nevertheless, with stringent safeguards, it can exist used even in the absence of consent in research and teaching. Regulations are required to command the storage of all such human material, along the lines of regulations governing anatomy body bequests.

The utilise of human tissue has been integral to medical inquiry and teaching for many years, and information technology has frequently been argued that this is essential for the continued flourishing of both areas.one The removal of tissues and organs from dead bodies has traditionally occurred, yet, in an upstanding vacuum. Until the 1960s this may have been acceptable by the standards (and mayhap legislation) of the time. Changes in the public's sensation of medical procedures have, nonetheless, brought the practice into the spotlight and have resulted in widespread scrutiny. This has been especially true where the do connected into the 1990s, and has led to a plethora of inquiries over the retention of body parts and organs from postmortem examinations.2– 4 In addition, there accept been a variety of scandals in the United States, involving anatomy departments, tissue banks, not-profit and for profit private biotechnology companies,v, 6 and more recently, crematoria.seven
In view of these developments, professional person, and governmental bodies accept been assessing the size of the problem and, more significantly, the issues implicit within it.eight– 12 These reports have underlined the centrality of a number of principles when dealing with retained organs and tissues, such as respect for the person who has died and also for their family, the role of agreement and informed consent, and a diversity of cultural pressures. The significance of a gift relationship, with emphasis on the donation of organs and tissues rather than on taking and retaining them, has also been underlined.11, thirteen
Information technology is living people who are principally affected by what is done to cadavers and torso parts, hence the full general assumption that it is their consent that is crucial.1 Consider the following: if internal organs are removed from a cadaver, post-obit appropriate consent by the person prior to decease and/or living relatives at the time of death, the integrity of that cadaver has been retained. The wishes and expectations of those involved have been respected. Conversely, when consent has not been given, the cadaver has been desecrated. Biologically, the two cadavers are identical, but there is a symbolic difference betwixt the two. These considerations lead to an accent upon showing respect for human fabric, as well as to what Walkerfour has termed reticence: "doing no more what can be justified in advance on reasonable and decent criteria for the benefit of scientific discipline, justice, and social club".
Unfortunately, such principles appear to have been neglected past the way in which organs, body parts, and tissues take been retained post-obit postmortem examinations and operations. In recent reports, the greatest attention has been paid to stored body parts of relatively contempo acquisition, and with protocols for obtaining body parts today. This is understandable, but surprisingly limited attention has been paid to archival material, an enormous corporeality of which is in existence, and which in some cases has been collected since the end of the nineteenth century. Many of these collections establish the courage of medical education and research, and even so the ethical issues involved in their continued usage have been barely explored.
NATURE OF ARCHIVAL MATERIAL
The term "archival" is generally considered to embrace the long term preservation of tissue or organs,9 although it may also be used in a more specific sense to refer to pathological archives of histological slides, such as stained blood and bone marrow films for haematological examination.viii In this sense textile can be considered to exist archival once the decision has been taken to retain it for future reference, pregnant that it is retained beyond the period necessary to constitute the crusade of death or is surplus to requirements for medical diagnosis.14 Pathological archives of this nature are considered essential for quality control and assurance, allowing review of diagnoses and for establishing the natural history of diseases. They take played a role in identifying new varieties of tumours, informing decisions concerning therapy and evaluating the effectiveness of various medicines. Pathological athenaeum accept a clearly defined focus, that of enhancing medical agreement, and then their storage is governed by the reasons for their initial retention.
Newborn screening fits into a category of its ain; in this a claret spot is obtained to test for a range of diseases. The blood, all the same, may exist stored for many years in an identifiable form and may be used for a variety of purposes unrelated to diagnosis of any of the conditions for which it was originally obtained. While storage of blood is not the subject area of this paper, it raises policy issues relating to mandatory and voluntary screening and the nature of the consent obtained for any subsequent employ.15
Much other human textile (both normal and pathological) is also retained, although the reasons for this may be far less well defined, beingness used in a wide range of inquiry and in the education and grooming of medical and allied students. Cloth such as this has often been stored for very long periods of fourth dimension and forms the basis of museum collections, dating in some cases from the nineteenth century. We may refer to these as museum archives, with material coming from postmortem examinations, surgical operations and, in anatomy museums, from bodies bequeathed to anatomy departments.
A concept related to archival textile is that of anonymity. In general this term is used to refer to unidentified specimens, that is, specimens that cannot exist linked in any way to a known individual or individuals. Since the major use of archival material is in the advancement of knowledge of disease in general and specific diseases in particular, and in education, at that place is generally no demand to link samples to known individuals. It is entirely appropriate therefore, that storage should be anonymous. A related term is anonymised, where a specimen has been rendered anonymous by removing identifiers or codes to link information technology to known individuals; such specimens are also termed unlinked specimens.16, 17
Museum archives consist largely of anonymous archival material. Of this, older fabric dating from before the 1960s or early 1970s can be referred to as "celebrated archival" material. The twelvemonth 1970 has been used as an arbitrary demarcation point in the United kingdom of great britain and northern ireland by the Department of Wellness.x The twelvemonth 1961 may as well be used, since prior to this twelvemonth in the United kingdom of great britain and northern ireland stipulation of non-objection to organ retention following postmortem examinations was not nowadays.13
Since bearding archival material has been retained and stored for well over one hundred years, the result is a sizeable source of human tissue archived in pathology repositories, anatomy departments, medical schools, and museums worldwide. As of 1999 in England, an estimated 104 300 organs, trunk parts, stillbirths or fetuses retained from postmortem examinations are held past pathology services. There are an additional 480 600 samples of tissue similarly stored in museums and other athenaeum,10
Historic archival cloth would have been obtained in a multifariousness of ways, and in diverse legal and upstanding climates. As a result, it has no known links to its original bailiwick, no information is bachelor regarding whether consent was obtained, there is no indication of the intended purpose of the tissue, and niggling or nothing may be known about the method of acquisition of the tissue. At the University of Otago the beefcake museum has material dating from 1879, only three years after the beginnings of the medical school, through to the nowadays day. While at that place is only limited evidence of consent for the pre-1970s material, all the more than contempo material (which by definition is non archival) has been from cadavers bequeathed to the anatomy department in terms of the local human tissue act.
OPTIONS IN THE Use OF ARCHIVAL MATERIAL
Does the storage of textile like this raise ethical dilemmas? Various answers have been given. For instance, the Retained Organs Commission13 stated that "the views of family members and the historic and educational value of the collections need to be considered before decisions are taken on retention or disposal". The emphasis here is that tissues and organs are to exist treated with respect, and that whatever is done to these collections should be in line with society'southward electric current expectations.
A somewhat different perspective emerged from the National Bioethics Informational Committee16 in the U.s., which concluded that inquiry on already existing unidentifiable (anonymous or anonymised) specimens should non be classed equally research with man subjects. Consequently, neither informed consent nor ideals review is required. This conclusion was based on the view that inquiry using human being subjects involves an intervention or interaction with a living person. Since archival and museum specimens are already in being, at that place is no demand for such interaction since there is no chance to the donor.17 It was the commission's view that restrictions imposed on the employ of stored anonymous tissue could seriously hinder potentially valuable enquiry projects.
A similar stance has been expressed past Knoppers and Laberge,xviii who have warned against the "sacralisation" of stored samples. Their business stems from what they perceive to be an excessive desire to control the employ of human organs and tissues in an attempt to protect privacy and autonomy. They debate that if nosotros neglect to distinguish samples from persons, we will end up encouraging reductionism rather than individual integrity.
The view of the Royal College of Physicians14 is that enquiry on archival cloth is ethical even in the absence of the consent of individual patients, subject to certain provisos. These include anonymisation of the material equally early equally possible in the research procedure, an assurance that subjects are non inconvenienced in any way, and that consent is obtained if doubt surfaces about the intrusive nature of the research. These provisos do not apply to bearding archival material, where in that location is no possible link to known patients or their relatives.
What are nosotros to make of these differing perspectives? Since this material is anonymous there will be no next of kin to consult. Consequently, decisions volition take to be taken by those in lawful possession of the material. What will be in the best interests of the human community? What volition show the greatest respect to those people from whom this material was taken in the commencement identify, in all probability without their consent?
A starting time option is to dispose of the tissue through burial or incineration every bit clinical waste. This line of action would not directly benefit any party, although information technology would foreclose the perceived misuse or abuse of the tissue. Does the mere disposal of tissue serve any positive purpose?1 Since the material exists, something has to be done with information technology. Disposal is possible, merely this is not an ethically neutral action, since it presupposes that disposal is preferable to its use for teaching and/or research purposes. We remain to be convinced that disposal as such has any merits when considered aslope a use of potential benefit to members of the human community. Even if disposal demonstrates respect for unknown patients in the past, it achieves this by accentuating the effects of the brunt of disease on electric current and futurity patients.19
A 2d option is apply of the tissue in education, an option intended to produce firsthand educational do good. While not all stored tissues will be suitable for pedagogy, it is an pick that volition employ to some collections. We consider that education is a legitimate employ to which some anonymous archival cloth may exist put. This prospect does not, still, justify the retention of tissue in the vague hope that it may serve some sick defined education purpose at some indefinite fourth dimension in the hereafter. The teaching rationale should be a focused ane, and should exist based on clearly articulated teaching goals.
A third pick is for the tissue to be used in inquiry. The justification in this case depends upon the potential usefulness of the tissue in research. This will not utilize to all tissue in storage, and information technology has to be determined which tissue falls into this category. Nonetheless, research on appropriate tissue may atomic number 82 to considerable insights into clinical conditions and benefits to patients in the future, opening upwards the possibility of carrying out some research under clearly circumscribed atmospheric condition. This pick includes the retentiveness of material for audit purposes.13
A 4th option is that the tissue remains in storage. Even if continued storage is of lilliputian firsthand benefit, this option allows for the use of the tissue in future research projects, providing it is treated with intendance and respect. A audio inquiry rationale has to include potential time to come benefits to science and medicine, even though precision in this surface area is beyond our grasp. On the other hand, the mere stockpiling of tissue, like the stockpiling of raw data, in the absence of a disarming research prototype, is ethically unacceptable. This is a practice that lay at the heart of a number of the organ retentiveness sagas, and that has come in for justified criticism since information technology is closely linked with a failure to involve families as equal partners and with a lack of respect for the dead.xi
None of these options accepts that human tissue can be kept indefinitely for no good reason, or that it can be used for ethically dubious and/or scientifically substandard research. What emerges is that the potential scientific and clinical value of human tissue in storage should be taken into consideration when determining what can or cannot be done with it. While it is preferable to apply human tissue for which specific consent has been given for its use in teaching and research, the paucity of such recently acquired human tissue emphasises the crucial instruction and research role of stored tissue.
Our argument is that ethical justification is required for retaining human tissue, and storage in the absence of a legitimate scientific employ fails to satisfy this benchmark.1, 20 The parallel between this situation and that applying to human being skeletal remains is compelling, since in the latter ethical justification is required for retaining skeletal remains.20 If there is even the merest hint that some stored material might be identifiable, efforts should be made to identify next of kin and obtain consent. The ethical balance should always be weighted in favour of obtaining consent if at all feasible. Information technology is only where this is not possible, that the above conclusions utilise.
Terminate LEVEL SAFEGUARDS WHEN USING ARCHIVAL MATERIAL WITHOUT CONSENT
It is widely accepted that informed consent must exist obtained for projects that involve the straight prospective involvement of human subjects. The office of consent is much more opaque, however, when information technology comes to research involving the employ of man tissue rather than human subjects themselves. This is to be expected considering a person has higher value than that attributed to his or her body parts.21 The essence of the debate over anonymous archival material is that it represents a further motility away from an bodily subject area; indeed, the actual field of study has disappeared completely from view. Past contrast, where tissue tin can be traced back to a human person, the onus is on the researcher to demonstrate that the field of study (or next of kin) approves of the use to which information technology will be put. Only in this manner are the autonomy of persons and respect for them safeguarded.11, 13, 19
The ambiguity of consent in the context of cadavers and body parts has been addressed recently past various legal writers. Bricklayer and Laurie22 accept that a consent model is to exist preferred to a holding model, and yet they recognise that the consent model retains aspects of the language of the property model. For them, relatives of the deceased can either assent or dissent to invasion of the dead body, but cannot consent under the terms of the 1961 United kingdom Human Tissue Act. They also argue that relatives should have interim property rights over the cadaver pending disposal of the body. Skene23 takes this further by contending that, while people should have an autonomy right to allow or prohibit their bodies and torso parts being used for research, pedagogy, or therapy, they should not have proprietary rights (of ownership and control) in relation to the parts removed with their consent. That should reside with the person or institution holding them, who in plow should apply them for advisable medical or scientific purposes nether ethical scrutiny.
This tentative motion from a fully consent based ethics towards one acknowledging some property interests is of particular relevance for bearding archival human being textile. In this state of affairs, whatsoever property interests in the man textile take precedence over consent which is lacking. This is a compromise state of affairs, and those in possession of the material have compelling upstanding obligations to use information technology in means that will be of value in teaching, research, or diagnostic audit.
Archival textile has already been obtained and and so in that location is no boosted hazard to the enquiry subject from concrete intervention.fourteen Past definition, anonymous archival material has no links with an original field of study, and and then no harm can be done to a subject. Information technology is for this reason that we reject the exclamation that a wrong is being performed by invading the subject'southward privacy and by treating them as a means to an end.24 Any such harms are no more than postulated ones, which have to be balanced confronting the harms and wrongs to science, medicine, and guild if research on this type of archival textile is seriously hindered.
Should identifiable tissue be anonymised once the immediate uses for which it was collected take been fulfilled? The assumption here is that the fabric was offset collected with consent in order to undertake specified procedures on it. In our view, anonymisation tin can but be justified if the initial consent encompassed the possibility of subsequent anonymisation for further teaching or inquiry purposes. While the nature of the research procedures cannot be spelled out in particular, broad directions should exist given. In particular, whatever likelihood that it could be used for commercial purposes or that it could exist linked to identifiable data would have to be stated. It is our view that no assart should be made for commercial use of tissue unless consent was obtained when collected. If appropriate consent for hereafter uses has not been included in the consent obtained for recently acquired tissue, the tissue cannot be used in further means. To do so is to override the dimensions of the consent provided, and show lack of respect for those providing this consent.
An analogy is that provided past epidemiological data. It tin can be argued that, simply as data (about the liver, say) are impersonal, a liver or liver slice is impersonal when it cannot in any way exist traced to an identifiable private. It is a source of information alike to that of epidemiological data. Confidentiality must be protected, and the enquiry must be of sufficient importance to outweigh whatever perceived "wrongs" pertaining to the utilise of this textile. This is an interesting illustration, but it breaks downward on two counts. Epidemiological data should not be obtained without consent; the lack of consent with anonymous archival tissue reflects an historic situation rather than an accustomed contemporary protocol. Secondly, treating human tissue as epidemiological data is problematic since it is more than this. Once epidemiological data have been collected, new information can only be gleaned from that data by reassessing it. By dissimilarity, human being tissue is a raw material from which considerable new information can be garnered by using additional techniques and investigative procedures. In other words, stored human tissue has the adequacy of giving rise to new knowledge and concepts, thereby placing it in a different category from that of epidemiological data. Additionally, the use of human tissue is a privilege that must be respected. Consequently, the use of human tissue in research requires more than stringent restrictions and controls than those applied to the employ of epidemiological data.
The availability of, and subsequent study of, archival material will be a compromise, and intendance needs to be taken to ensure that its use never leads to a diminution in the respect shown the human body and its parts.25 Routinely, it is preferable to err on the side of altruism, with its accent on a gift relationship, and hence for consent for the utilize of all newly acquired human tissue. This is non possible with anonymous archival material, since it is not possible to go back to any donors for consent.12 There were no voluntary donors, and that is regrettable. Nevertheless, archival samples should be treated with the same care and respect as if they had been donated, and as if they had been gifts. This is possible if those in charge of the cloth act every bit its custodians rather than its owners,12 with responsibility for safe storage of the samples, for its appropriate use, and for the quality of the research carried out on it.
Further CONSIDERATIONS
Consternation over the removal of organs from cadavers without consent revolves principally around sure organs, notably, the heart and brain.xi The memory of pocket-size tissue samples does not appear to have the aforementioned cultural and emotional significance as retentivity of larger tissue specimens or whole organs.19 A brain, a kidney, or a limb, for example, are perceived quite differently from a blood sample or a bone sliver.26 We fence that stringent consent is required for the removal of a brain, and far less, if any, for the removal of sebaceous glands or a mucous membrane lining the rima oris. Here nosotros are in line with a number of others who propose that tissue blocks and histology slides might be excluded from a definition of human material, since they incorporate small-scale amounts of tissue and much of the tissue has been replaced with paraffin wax or chemicals.4, 13 Additionally, postmortem exam involves fragmentation of organs to varying degrees, in accordance with adept medical practice.22
This reflects a gradation of biological value from tissues vital to the connected existence of an individual, through to those of little significance for human functioning. Unless a line of demarcation is placed along this continuum, information technology becomes impossible to make whatever ethically relevant distinction between, say, memory of the brain and retentivity of hair. Clinically, there appears to exist a gap of major clinical significance betwixt essential simply replaceable organs (centre, kidneys) and nonessential organs (spleen, appendix). This tends to represent to a symbolically significant gap, although the footing for giving this ethical weight is far from clear. Our proffer is that whatsoever organs are essential for the functioning of homo persons during life serve as a criterion for the significance to be bestowed upon them at decease. While this does not settle issues of consent, it provides a guide to its stringency.
General as these considerations are, they too apply to the treatment of bearding archival material in museums, since this reflects order's or an individual'due south attitudes towards that material. Given the considerable distance between archival material and actual living persons, any symbolism attached to it volition exist far less than in the case of identifiable remains although it will non take disappeared completely. While respect for human fabric should be universal, regulations governing its retention and use should exist most demanding for brains and hearts, and least demanding for tissue blocks and histology slides.
Archival material will accept emanated from postmortem examinations, surgical operations, and bodies ancestral to anatomy departments. Of these iii sources, the only ane covered past regulations will be the bequeathed bodies. More often than not, the control exercised in this latter situation is far more stringent and overarching than that exercised in any of the other areas discussed.13, 27 In the case of bequeathed bodies, informed consent is central and the command over them continues as long as they are held by anatomy departments—for example, Human Tissue Human activity 1961 or Anatomy Human action 1984 in the UK; Homo Tissue Act 1964 in New Zealand. This includes retentiveness in museums. By contrast, other celebrated archival material is nether no legal jurisdiction (neither is identifiable tissue obtained with consent).
Neither the lack of informed consent for the conquering of anonymous archival material, nor regarding the material every bit property, is sufficient reason for allowing museum collections to remain unregulated. Regulations are urgently required to control the storage of all such homo material, and these should have note of those currently in place for governing bodies bequeathed to anatomy departments.11, 13, 27
Forth these lines we envisage the following:
-
registration and licensing of collections, with external monitoring and accreditation
-
all collections to be included, although time may exist required to determine the fate of smaller collections
-
all collections would exist brought under the aforementioned regulatory framework, thereby eliminating any distinction betwixt pathology and anatomy collections; in this fashion, a one tier oversight of all body parts could be provided, covering man textile obtained at postmortem examination and operation, also as anonymous archival material
-
appointment of licensed staff with expertise in medical and/or allied biomedical disciplines to practice curatorial responsibilities for collections
-
all collections to have detailed records of all human specimens and body parts in their collections (although tissue blocks, slides, and plastinated slices could be excluded)
-
all collections would have their own ethics committees to oversee approval of research projects, teaching usage, and diagnostic audits; these committees would themselves exist appropriately accredited.
