Organ donation after cardiac death (DCD) is one promising possibility of combating the organ shortage, but it raises ethical issues that differ from those raised in donation after brain death (DBD). Also, DCD may be perceived differently than DBD by medical staff and the public. The aim of this article is to systematically review empirical studies on attitudes of medical personnel and the public toward DCD and to discuss the findings from an ethical perspective. Our study was conducted in accordance with a seven-step approach for systematic reviews of empirical studies in bioethics.
The authors chose PubMed, EMBASE, CINAHL, PSYCINFO, and PSYNDEX, thus attempting to cover biomedical, sociological and ethical articles on the subject.
A search algorithm using controlled vocabulary of the respective databases (where applicable) was created, and criteria for the relevance assessment of the articles were established. Article quality was assessed using the Critical Appraisal Skills Programme tool.
The authors took an integrative approach to the data, combining it for further analysis. Qualitative data were synthesized by means of thematic analysis, and a spectrum of relevant themes was identified. Then the authors extracted the quantitative data that corresponded with the identified themes. Quantitative data on common subjects were juxtaposed and presented later.
Identified themes were the levels of support for DBD vs. DCD, attitudes toward postmortem measures without previous consent, lack of knowledge about DCD, concerns about the Dead Donor Rule, the potential for conflict of interest, making donation happen, and the call for standardized DCD protocols. All of these issues are of ethical relevance and merit further discussion. We conclude that deep-rooted concerns about DCD exist among medical personnel and the general public. These need to be taken seriously in order to maintain or foster trust in the transplantation system.
心死亡后器官捐献(DCD)是解决器官短缺的一种有前途的方法,但它引发了与脑死亡后捐献(DBD)不同的伦理问题。此外,DCD 可能会被医务人员和公众以与 DBD 不同的方式感知。本文的目的是系统地回顾关于医务人员和公众对 DCD 的态度的实证研究,并从伦理角度讨论这些发现。我们的研究是按照生物伦理学实证研究系统评价的七步方法进行的。
作者选择了 PubMed、EMBASE、CINAHL、PSYCINFO 和 PSYNDEX,试图涵盖关于该主题的生物医学、社会学和伦理学文章。
创建了使用各自数据库(适用时)受控词汇的搜索算法,并为文章相关性评估制定了标准。使用批判性评估技能计划工具评估文章质量。
作者对数据采用了综合方法,将其进行了进一步分析。通过主题分析对定性数据进行综合,并确定了一系列相关主题。然后,作者提取了与已确定主题相对应的定量数据。将常见主题的定量数据并列呈现。
确定的主题包括对 DBD 与 DCD 的支持程度、对未经事先同意进行死后措施的态度、对 DCD 缺乏了解、对“死体供者规则”的担忧、潜在的利益冲突、促成捐赠、以及呼吁制定标准化的 DCD 方案。所有这些问题都具有伦理相关性,值得进一步讨论。我们得出结论,医务人员和公众对 DCD 存在根深蒂固的担忧。为了维护或培养对移植系统的信任,这些担忧需要认真对待。
