A shortage of transplantable organs is a global problem. There are two types of organ donation: living and deceased. Deceased organ donation can occur following neurological determination of death (NDD) or cardiocirculatory death. Donation after cardiocirculatory death (DCD) accounts for the largest increments in deceased organ donation worldwide. Variations in the use of DCD exist, however, within Canada and worldwide. Reasons for these discrepancies are largely unknown. The purpose of this study is to develop, implement, and evaluate a theory-based knowledge translation intervention to provide practical guidance about how to increase the numbers of DCD organ donors without reducing the numbers of standard NDD donors.
We will use a mixed method three-step approach. In step one, we will conduct semi-structured interviews, informed by the Theoretical Domains Framework, to identify and describe stakeholders' beliefs and attitudes about DCD and their perceptions of the multi-level factors that influence DCD. We will identify: determinants of the evidence-practice gap; specific behavioural changes and/or process changes needed to increase DCD; specific group(s) of clinicians or organizations (e.g., provincial donor organizations) in need of behaviour change; and specific targets for interventions. In step two, using the principles of intervention mapping, we will develop a theory-based knowledge translation intervention that encompasses behavior change techniques to overcome the identified barriers and enhance the enablers to DCD. In step three, we will roll out the intervention in hospitals across the 10 Canadian provinces and evaluate its effectiveness using a multiple interrupted time series design.
We will adopt a behavioural approach to define and test novel, theory-based, and ethically-acceptable knowledge translation strategies to increase the numbers of available DCD organ donors in Canada. If successful, this study will ultimately lead to more transplantations, reducing patient morbidity and mortality at a population-level.
器官短缺是一个全球性问题。器官捐献有两种类型:活体捐献和死后捐献。死后捐献可在确定脑死亡(NDD)或心源性死亡(cardiocirculatory death)后进行。心源性死亡后捐献(DCD)占全球死后器官捐献的最大增量。然而,加拿大和全球范围内 DCD 的使用存在差异。造成这些差异的原因在很大程度上尚不清楚。本研究的目的是开发、实施和评估一项基于理论的知识转化干预措施,为如何在不减少标准 NDD 供体数量的情况下增加 DCD 供体数量提供实用指导。
我们将采用混合方法三步法。在第一步中,我们将进行半结构化访谈,以理论领域框架为指导,确定和描述利益相关者对 DCD 的信念和态度,以及他们对影响 DCD 的多层次因素的看法。我们将确定:证据-实践差距的决定因素;增加 DCD 需要的具体行为和/或流程变化;需要行为改变的特定临床医生或组织(例如,省级供体组织);以及干预措施的具体目标。在第二步中,我们将根据干预映射的原则,开发一项基于理论的知识转化干预措施,包括行为改变技术,以克服已确定的障碍并增强对 DCD 的促进因素。在第三步中,我们将在加拿大的 10 个省的医院推出干预措施,并使用多个中断时间序列设计评估其有效性。
我们将采用行为方法来定义和测试新的、基于理论的、符合伦理的知识转化策略,以增加加拿大可用于 DCD 的器官供体数量。如果成功,这项研究最终将导致更多的移植,减少人群水平的患者发病率和死亡率。
