临床研究中延迟知情同意的探讨

Exploration of deferred informed consent in clinical research

知情同意是临床研究中重要的伦理标志,在开展临床研究前,研究人员有责任将研究信息充分告知参与者。然而,在紧急情况下开展的临床研究,让其中的参与者或其监护人在狭窄的治疗时间窗口内完全知情同意很难做到。目前现实中可接受的知情同意方式除传统的一般知情同意外,还有豁免知情同意、泛知情同意以及延迟知情同意。通过介绍临床研究中延迟知情同意起源和发展历程,对延迟知情同意的应用现状进行梳理,提出紧急情况下应用延迟知情同意的先决条件并针对延迟知情同意应用过程中需要注意的问题进行探讨,以期为紧急情况下临床研究延迟知情同意的应用提供伦理辩护和伦理程序。

Informed consent is an important ethical symbol in clinical research,and researchers have the responsibility to fully inform participants of the research information before conducting clinical research.However,it is difficult to obtain complete informed consent form participants or their guardians within a narrow treatment time period in clinical research conducted in emergency situations.Currently,in addition to traditional general informed consent,there are also reality-accepted informed consent,including exemption of informed consent,broad informed consent,and deferred informed consent.By introducing the origin and development process of deferred informed consent in clinical research,this paper sorted out the current application status of deferred informed consent,proposed the prerequisites for applying deferred informed consent in emergency situations,and explored the issues that need to be noted during the application process of deferred informed consent.It is hoped to provide an ethical defense and ethical procedure for the application of deferred informed consent in clinical research in emergency situations.
