Recently, the news media have reported on the discovery of covert awareness and the establishment of limited communication using a functional magnetic resonance imaging (fMRI) neuroimaging technique with several brain-injured patients thought to have been in a vegetative state. This discovery has raised many ethical, legal, and social questions related to quality of life, end-of-life decision making, diagnostic and prognostic accuracy in disorders of consciousness, resource allocation, and other issues. This project inquires into the public responses to these discoveries.
We conducted a thematic analysis of online comments (n = 779) posted in response to 15 news articles and blog posts regarding the case of a Canadian patient diagnosed for 12 years as in a vegetative state, but who was reported in 2012 as having been able to communicate via fMRI. The online comments were coded using an iteratively refined codebook structured around 14 main themes.
Among the most frequent public reactions revealed in the online comments were discussions of the quality of life of patients with disorders of consciousness, whether life-sustaining treatment should be withdrawn (and whether the fMRI communication technique should be used to ask patients about this), and misgivings about the accuracy of diagnosis in disorders of consciousness and brain death.
These public perspectives are relevant to the obligations of clinicians, lawyers, and public policymakers to patients, families, and the public. Future work should consider how best to alleviate families' concerns as this type of research shakes their faith in diagnostic accuracy, to clarify the legal rules relating to advance directives in this context, and to address the manner in which public messaging might help to alleviate any indirect impact on confidence in the organ donation system.
最近,新闻媒体报道了关于隐性意识的发现,以及利用功能磁共振成像(fMRI)神经成像技术与几名被认为处于植物人状态的脑损伤患者建立有限沟通的情况。这一发现引发了许多与生活质量、临终决策、意识障碍的诊断和预后准确性、资源分配及其他问题相关的伦理、法律和社会问题。本项目探究公众对这些发现的反应。
我们对针对15篇关于一名被诊断为植物人状态达12年的加拿大患者的新闻文章和博客文章所发表的在线评论(n = 779)进行了主题分析。该患者于2012年被报道能够通过fMRI进行沟通。在线评论使用围绕14个主要主题构建的经过反复完善的编码手册进行编码。
在线评论中最常见的公众反应包括对意识障碍患者生活质量的讨论、是否应停止维持生命的治疗(以及是否应使用fMRI沟通技术询问患者对此的看法),以及对意识障碍和脑死亡诊断准确性的疑虑。
这些公众观点与临床医生、律师和公共政策制定者对患者、家属及公众的义务相关。未来的工作应考虑如何最好地减轻家属的担忧,因为这类研究动摇了他们对诊断准确性的信心,应在此背景下澄清与预先指示相关的法律规则,并探讨公众信息传播可能有助于减轻对器官捐赠系统信心的任何间接影响的方式。
