Since the inception of transplantation, it has been crucial to ensure that organ or tissue donations are made with valid informed consent to avoid concerns about coercion or exploitation. This issue is particularly challenging when it comes to infants and younger children, insofar as they are unable to provide consent. Despite their vulnerability, infants' organs and tissues are considered valuable for biomedical purposes due to their size and unique properties. This raises questions about the conditions under which it is permissible to remove and use these body parts for transplantation, research, or commercial purposes. The aim of this protocol is to establish a foundation for a scoping review that will identify, clarify, and categorise the main ethical arguments regarding the permissibility of removing and using organs or tissues from infants. The scoping review will follow the methodology outlined by the Joanna Briggs Institute (JBI), consisting of five stages: (1) identifying the research question, (2) developing the search strategy, (3) setting inclusion criteria, (4) extracting data, and (5) presenting and analysing the results. We will include both published and unpublished materials that explicitly discuss the ethical arguments related to the procurement and use of infant organs or tissues in the biomedical context. The search will cover various databases, including the National Library of Medicine, Web of Science, EBSCO, and others, as well as grey literature sources. Two raters will independently assess the eligibility of articles, and data from eligible studies will be extracted using a standardised form. The extracted data will then be analysed descriptively through qualitative content analysis.
There has been debate about how to respect the rights and interests of organ and tissue donors since the beginning of transplantation practice, given the moral risks involved in procuring parts of their bodies and using them for transplantation or research. A major concern has been to ensure that, at a minimum, donation of organs or other bodily tissues for transplantation or research is done under conditions of valid informed consent, so as to avoid coercion or exploitation among other moral harms. In the case of infants and younger children, however, this concern poses special difficulties insofar as infants and younger children are deemed incapable of providing valid consent. Due to their diminutive size and other distinctive properties, infants' organs and tissues are seen as valuable for biomedical purposes. Yet, the heightened vulnerability of infants raises questions about when and whether it is ever permissible to remove these body parts or use them in research or for other purposes. The aim of this protocol is to form the basis of a systematic scoping review to identify, clarify, and systematise the main ethical arguments for and against the permissibility of removing and using infant or newborn (hereafter, "infant") organs or tissues in the biomedical context (i.e. for transplantation, research, or commercial purposes).
Our scoping review will broadly follow the well-established methodology outlined by the Joanna Briggs Institute ( Peters , 2020). We will follow a five-stage review process: (1) identification of the research question, (2) development of the search strategy, (3) inclusion criteria, (4) data extraction, and (5) presentation and analysis of the results. Published and unpublished bibliographic material (including reports, dissertations, book chapters, etc.) will be considered based on the following inclusion criteria: the presence of explicit (bio)ethical arguments or reasons (concept) for or against the procurement and use of organs or tissues from infants, defined as a child from birth until 1 year old (population), in the biomedical domain, including transplantation, research, and commercial development (context). We will search for relevant studies in the National Library of Medicine (including PubMed and MEDLINE), Virtual Health Library, Web of Science, Google Scholar, EBSCO, Google Scholar, PhilPapers, The Bioethics Literature Database (BELIT), EthxWeb as well as grey literature sources (e.g., Google, BASE, OpenGrey, and WorldCat) and the reference lists of key studies to identify studies suitable for inclusion. A three-stage search strategy will be used to determine the eligibility of articles, as recommended by the JBI methodological guidelines. We will exclude sources if (a) the full text is not accessible, (b) the main text is in a language other than English, or (c) the focus is exclusively on scientific, legal, or religious/theological arguments. All articles will be independently assessed for eligibility between two raters (MB & XL); data from eligible articles will be extracted and charted using a standardised data extraction form. The extracted data will be analysed descriptively using basic qualitative content analysis.
Ethical review is not required as scoping reviews are a form of secondary data analysis that synthesise data from publicly available sources. Our dissemination strategy includes peer review publication, presentation at conferences, and outreach to relevant stakeholders.
The results will be reported according to the PRISMA-ScR guidelines. An overview of the general data from the included studies will be presented in the form of graphs or tables showing the distribution of studies by year or period of publication, country of origin, and key ethical arguments. These results will be accompanied by a narrative summary describing how each included study or article relates to the aims of this review. Research gaps will be identified and limitations of the review will also be highlighted.
A paper summarising the findings from this review will be published in a peer-reviewed journal. In addition, a synthesis of the key findings will be disseminated to biomedical settings (e.g., conferences or workshops, potentially including ones linked to university hospitals) in the UK, USA, Türkiye, and Singapore. They will also be shared with the academic community and policy makers involved in the organ procurement organisations (OPO), which will potentially consider our recommendations in their decision-making processes regarding infant tissue/organ donation practice in these countries.
The use of a rigorous, well-established methodological framework will ensure the production of a high-quality scoping review that will contribute to the bioethics literature.A comprehensive search of disciplinary and cross-disciplinary databases will be undertaken to ensure coverage of all possible sources that meet the inclusion criteria for the review.This review will focus exclusively on infant tissue/organ procurement/use in biomedical contexts, providing a comprehensive and reliable source of ethical arguments for future debates on this sensitive topic.The review will be limited to articles published in English, which increases the risk of missing relevant sources published in other languages.The review will be limited to articles for which the full text is available, which increases the risk of missing relevant sources that otherwise may have been included in the scoping review had the full text been accessible.
自移植技术诞生以来,确保器官或组织捐赠是在有效知情同意的情况下进行,对于避免强迫或剥削等问题至关重要。当涉及婴儿和年幼儿童时,这个问题尤其具有挑战性,因为他们无法提供同意。尽管婴儿易受伤害,但由于其尺寸和独特特性,其器官和组织在生物医学领域被认为具有价值。这就引发了关于在何种条件下可以摘除并使用这些身体部位进行移植、研究或商业目的的问题。本方案的目的是为一项范围综述奠定基础,该综述将识别、阐明并分类有关从婴儿身上摘除和使用器官或组织的主要伦理论点。范围综述将遵循乔安娜·布里格斯研究所(JBI)概述的方法,包括五个阶段:(1)确定研究问题,(2)制定检索策略,(3)设定纳入标准,(4)提取数据,以及(5)呈现和分析结果。我们将纳入已发表和未发表的材料,这些材料明确讨论了在生物医学背景下与获取和使用婴儿器官或组织相关的伦理论点。检索将涵盖各种数据库,包括美国国立医学图书馆、科学网、EBSCO等,以及灰色文献来源。两名评估人员将独立评估文章的合格性,来自合格研究的数据将使用标准化表格进行提取。然后,通过定性内容分析对提取的数据进行描述性分析。
自移植实践开始以来,关于如何尊重器官和组织捐赠者的权利和利益一直存在争议,因为获取他们身体的部分并将其用于移植或研究存在道德风险。一个主要关注点是确保至少在有效知情同意的条件下进行器官或其他身体组织的捐赠用于移植或研究,以避免强迫或剥削以及其他道德伤害。然而,对于婴儿和年幼儿童而言,这一关注点带来了特殊困难,因为婴儿和年幼儿童被认为无法提供有效同意。由于婴儿体型小以及其他独特特性,其器官和组织在生物医学领域被视为有价值。然而,婴儿更高的脆弱性引发了关于何时以及是否允许摘除这些身体部位或在研究中或用于其他目的使用它们的问题。本方案的目的是形成一项系统范围综述的基础,以识别、阐明并系统化支持和反对在生物医学背景下(即用于移植、研究或商业目的)摘除和使用婴儿或新生儿(以下简称“婴儿”)器官或组织的主要伦理论点。
我们的范围综述将大致遵循乔安娜·布里格斯研究所(彼得斯,2020年)概述的既定方法。我们将遵循一个五阶段的综述过程:(1)确定研究问题,(2)制定检索策略,(3)纳入标准,(4)数据提取,以及(5)呈现和分析结果。已发表和未发表的文献资料(包括报告、论文、书籍章节等)将根据以下纳入标准进行考虑:在生物医学领域,包括移植、研究和商业开发(背景)中,存在支持或反对从婴儿(定义为从出生到1岁的儿童)获取和使用器官或组织的明确(生物)伦理论点或理由(概念)(人群)。我们将在国立医学图书馆(包括PubMed和MEDLINE)、虚拟健康图书馆、科学网、谷歌学术、EBSCO、谷歌学术、PhilPapers、生物伦理文献数据库(BELIT)、EthxWeb以及灰色文献来源(如谷歌、BASE、OpenGrey和WorldCat)以及关键研究的参考文献列表中搜索相关研究,以识别适合纳入的研究。将使用三阶段检索策略来确定文章的合格性,如JBI方法指南所建议。如果(a)无法获取全文,(b)正文语言不是英语,或(c)重点完全是科学、法律或宗教/神学论点,我们将排除这些来源。所有文章将由两名评估人员(MB和XL)独立评估合格性;来自合格文章的数据将使用标准化数据提取表格进行提取和制表。提取的数据将使用基本定性内容分析进行描述性分析。
由于范围综述是一种对公开可用来源的数据进行综合的二次数据分析形式,因此不需要伦理审查。我们的传播策略包括同行评审发表、在会议上展示以及向相关利益相关者进行推广。
结果将根据PRISMA - ScR指南进行报告。纳入研究的一般数据概述将以图表形式呈现,展示按发表年份或时期、原产国和关键伦理论点划分的研究分布。这些结果将伴有一篇叙述性总结,描述每项纳入研究或文章与本综述目的的关系。将识别研究差距并突出综述的局限性。
一篇总结本综述结果的论文将发表在同行评审期刊上。此外,关键结果的综合将传播到英国、美国土耳其和新加坡的生物医学环境(如会议或研讨会,可能包括与大学医院相关的会议或研讨会)。它们还将与参与器官采购组织(OPO)的学术界和政策制定者分享,这些组织可能会在这些国家关于婴儿组织/器官捐赠实践的决策过程中考虑我们的建议。
使用严谨、既定的方法框架将确保产生高质量的范围综述,这将为生物伦理文献做出贡献。将对学科和跨学科数据库进行全面搜索,以确保涵盖所有符合综述纳入标准的可能来源。本综述将专门关注生物医学背景下的婴儿组织/器官获取/使用,为关于这个敏感话题的未来辩论提供全面且可靠的伦理论点来源。综述将限于以英语发表的文章,这增加了遗漏其他语言发表的相关来源的风险。综述将限于可获取全文的文章,这增加了遗漏那些若能获取全文可能会被纳入范围综述的相关来源的风险。
