Current practice in organ donation after death determination by circulatory criteria (DCD) advises a five-minute observation period following circulatory arrest, monitoring for unassisted resumption of spontaneous circulation (i.e., autoresuscitation). In light of newer data, the objective of this updated systematic review was to determine whether a five-minute observation time was still adequate for death determination by circulatory criteria. ⋯ PROSPERO (CRD42021257827); registered 9 July 2021.

In this paper, we discuss situations in which disagreement or conflict arises in the critical care setting in relation to the determination of death by neurologic criteria, including the removal of ventilation and other somatic support. Given the significance of declaring a person dead for all involved, an overarching goal is to resolve disagreement or conflict in ways that are respectful and, if possible, relationship preserving. We describe four different categories of reasons for these disagreements or conflicts: 1) grief, unexpected events, and needing time to process these events; 2) misunderstanding; 3) loss of trust; and 4) religious, spiritual, or philosophical differences. ⋯ We propose several strategies for navigating these situations, appreciating that these may be tailored for a given care context and that multiple strategies may be helpfully used. We recommend that health institutions develop policies that outline the process and steps involved in addressing situations where there is ongoing or escalating conflict. These policies should include input from a broad range of stakeholders, including patients and families, as part of their development and review.

We aimed to describe the Canadian public's understanding and perception of how death is determined in Canada, their level of interest in learning about death and death determination, and their preferred strategies for informing the public. ⋯ Among the Canadian public, the understanding of neurologic and circulatory death determination is variable. More uncertainty exists with death determination by neurologic criteria than with circulatory criteria. Nevertheless, there is a high level of general interest in learning more about how death is determined in Canada. These findings provide important opportunities for further public engagement.

Review Meta Analysis
Diagnostic accuracy of ancillary tests for death by neurologic criteria: a systematic review and meta-analysis.
Ancillary tests are frequently used in death determination by neurologic criteria (DNC), particularly when the clinical neurologic examination is unreliable. Nevertheless, their diagnostic accuracy has not been extensively studied. Our objective was to synthesize the sensitivity and specificity of commonly used ancillary tests for DNC. ⋯ PROSPERO (CRD42013005907); registered 7 October 2013.
