The process of controlled organ donation after circulatory determination of death (cDCDD) results in ischaemic injury to organs and leads to poorer outcomes in organ recipients. Although not yet used in Canada, normothermic regional perfusion (NRP) is a perfusion technology used postmortem with cDCDD donors to selectively restore perfusion of oxygenated blood to target organs in situ, reversing ischaemic injury and improving organ viability and post-transplant outcomes. However, NRP poses significant ethical challenges. To preserve trust in deceased donation, these ethical challenges must be addressed to the satisfaction of Canadian stakeholders before NRP's implementation. This study will identify ethical issues pertaining to NRP and explore perspectives of NRP among key stakeholders. By developing an explanatory framework delineating how stakeholder perceptions of NRP's ethical implications impact trust in Canada's donation and transplantation systems, this study will inform the development of responsible policy on NRP's use in Canada.
This study includes two workstreams. Workstream 1 is a scoping review of medical and bioethical literature to identify ethical issues stemming from NRP. We will apply a common search string across Medline, PubMed (other than Medline) and Embase to identify relevant articles. We will identify grey literature through Google searches, websites of organ donation organisations and consultation with our research network. No date limits will be applied. All peer-reviewed publications, commentaries, editorials or documents that engage with ethical issues in NRP (or conceptual and empirical issues as they relate to these ethical issues) will be included. News articles, conference abstracts and publications not in English will be excluded. Workstream 2 consists of interviews with healthcare providers, institutional stakeholders, organ recipients and deceased donors' family members (n=24-36), as well as focus groups with healthcare providers involved in deceased donation and transplantation (n20-32). Constructivist grounded theory methodology will guide data collection and analysis in workstream 2.
This study was approved by Western University's research ethics committee (Western REM; ID: 120001). All participants will be asked to provide written informed consent to participate. Findings will be shared with Canadian organ donation and transplantation organisations, presented at national conferences and published in medical journals.
通过循环死亡判定(circulatory determination of death,cDCD)进行控制器官捐献会导致器官缺血损伤,从而使器官接受者的预后更差。虽然在加拿大尚未使用,但体温区域灌注(normothermic regional perfusion,NRP)是一种在 cDCD 供体死后使用的灌注技术,用于有选择性地恢复含氧血液向原位靶器官的灌注,逆转缺血损伤,提高器官活力和移植后效果。然而,NRP 带来了重大的伦理挑战。为了维护对死亡捐献的信任,在加拿大实施 NRP 之前,必须让加拿大的利益相关者满意地解决这些伦理问题。本研究将确定与 NRP 相关的伦理问题,并探讨关键利益相关者对 NRP 的看法。通过制定一个解释框架,阐明利益相关者对 NRP 伦理影响的看法如何影响对加拿大捐赠和移植系统的信任,本研究将为加拿大 NRP 使用的负责任政策提供信息。
本研究包括两个工作流程。工作流程 1 是对医学和生物伦理文献进行范围综述,以确定源自 NRP 的伦理问题。我们将在 Medline、PubMed(除 Medline 外)和 Embase 中应用一个共同的搜索字符串来识别相关文章。我们将通过 Google 搜索、器官捐赠组织的网站以及与我们的研究网络的协商来确定灰色文献。不设日期限制。所有同行评议出版物、评论、社论或涉及 NRP 伦理问题的文件(或与这些伦理问题相关的概念和经验问题),以及新闻文章、会议摘要和非英文出版物都将被排除在外。工作流程 2 包括对医疗保健提供者、机构利益相关者、器官接受者和已故供体的家属(n=24-36)进行访谈,以及对参与死亡捐赠和移植的医疗保健提供者进行焦点小组讨论(n20-32)。建构主义扎根理论方法将指导工作流程 2 中的数据收集和分析。
本研究已获得 Western 大学研究伦理委员会(Western REM;ID:120001)的批准。所有参与者将被要求提供书面知情同意书以参与研究。研究结果将与加拿大器官捐赠和移植组织分享,在全国会议上展示,并发表在医学期刊上。
