Ethical, practical, and medical challenges affect decisions about left ventricular assist device (LVAD) implantation. The informed consent document (IC-Doc) is integral to the decision-making process and structures informed consent conversations. The objective of this study was to analyze IC-Docs to identify the information patients and their families receive about LVAD implantation to create a model IC-Doc. We requested IC-Doc for LVAD implantation from LVAD programs in the United States. We analyzed them in three areas: medical and technical content, patient knowledge gaps, and syntax. Nineteen IC-Docs representing all United Network of Organ Sharing regions were included. Seventeen (89.5%) mentioned the indications for LVAD implantation (bridge to transplant or destination therapy), and six indicated which category applied to the patient. Palliative care was mentioned as an alternative in nine (47.4%); no IC-Doc discussed nonsurgical palliative care. Eight forms (42.1%) specifically mentioned turning off the LVAD. Eighteen forms mention general bleeding, and four referred to long-term gastrointestinal bleeding. Two IC-Docs addressed driveline infections. One form was written at an 8th grade reading level. There is wide variation in LVAD IC-Docs and omission of some benefits and risks. We have written an IC-Doc that meets criteria for disclosure, fills many knowledge gaps, and has an acceptable readability score.
伦理、实践和医学挑战影响左心室辅助装置 (LVAD) 植入的决策。知情同意书 (IC-Doc) 是决策过程的重要组成部分,构建了知情同意的对话。本研究的目的是分析 IC-Docs,以确定患者及其家属在 LVAD 植入方面获得的信息,从而创建一个模型 IC-Doc。我们向美国的 LVAD 项目请求 LVAD 植入的 IC-Doc。我们从三个方面对其进行了分析:医学和技术内容、患者知识差距和语法。纳入了代表所有美国器官共享网络区域的 19 份 IC-Docs。十七份(89.5%)提到了 LVAD 植入的适应症(桥接移植或终末期治疗),六份指出了哪种类别适用于患者。九份(47.4%)提到姑息治疗是一种替代方案;没有一份 IC-Doc 讨论非手术性姑息治疗。八份表格(42.1%)特别提到关闭 LVAD。十八份表格提到一般出血,四份提到长期胃肠道出血。两份 IC-Docs 涉及到电源线感染。一份表格的阅读水平为 8 年级。LVAD 的 IC-Docs 存在很大差异,并且遗漏了一些益处和风险。我们已经编写了一份符合披露标准、填补了许多知识空白且具有可接受的可读性评分的 IC-Doc。
