The participation of vulnerable patients in clinical research poses apparent ethical dilemmas. Depending on the nature of the vulnerability, their participation may challenge the ethical principles of autonomy, non-maleficence, or justice. On the other hand, non-participation may preclude the building of a knowledge base that is a prerequisite for defining the optimal clinical management of vulnerable patients. Such clinical uncertainty may also incur substantial economic costs.
We present the participation of pre-menopausal women with atrial fibrillation in trials of novel oral anticoagulant drugs as a case study. Due to their non-participation in pivotal trials, it is uncertain whether for them, the risks that are associated with these drugs are outweighed by the advantages compared with conventional treatment. We addressed the question whether research of this new class of drugs in this subgroup would be appropriate from both, an ethical as well an economic perspective. We used the method of specifying norms as a wider framework to resolve the apparent ethical dilemma, while incorporating the question whether research of oral anticoagulants in premenopausal women with atrial fibrillation can be justified on economic grounds. For the latter, the results of a value-of-information analysis were used.
Further clinical research on NOACs in premenopausal women with atrial fibrillation can be justified on both, ethical and economic grounds. Addressing apparent ethical dilemmas by invoking a method such as specifying norms can improve the quality of public practical reasoning. As such, the method should also prove valuable to committees that have formally been granted the authority to review trial protocols and proposals for scientific research.
脆弱患者参与临床研究带来了明显的伦理困境。根据脆弱性的性质,他们的参与可能会挑战自主、不伤害或公正等伦理原则。另一方面,不参与可能会阻碍知识库的建立,而知识库是确定脆弱患者最佳临床管理的先决条件。这种临床不确定性也可能产生巨大的经济成本。
我们以绝经前房颤女性参与新型口服抗凝药物试验为例进行阐述。由于她们未参与关键试验,所以不确定对于她们而言,与这些药物相关的风险与传统治疗相比,是否利大于弊。我们探讨了从伦理和经济角度来看,针对这一亚组进行这类新药研究是否合适的问题。我们采用规范细化方法作为一个更广泛的框架来解决明显的伦理困境,同时纳入了从经济角度来看,对绝经前房颤女性进行口服抗凝剂研究是否合理的问题。对于后者,使用了信息价值分析的结果。
从伦理和经济角度来看,对绝经前房颤女性进行关于新型口服抗凝剂的进一步临床研究都是合理的。通过采用规范细化等方法来解决明显的伦理困境,可以提高公共实践推理的质量。因此,该方法对于已被正式授权审查试验方案和科研提案的委员会也应具有价值。
