实施精准医学(PM)的证据要求,无论是基因组数据还是临床数据,都没有很好的定义。证据要求是由不确定性及其伴随的后果驱动的;这些方面可以通过卫生经济学中的一种新技术,信息分析价值(VOI)来量化。我们利用VOI分析比较基于药物基因组学与胺碘酮-华法林药物相互作用信息的华法林给药随时间推移的证据水平。主要结果是完美信息的期望值(EVPI),这是对进行未来研究的社会价值上限的估计。在过去的十年中,药物基因组学策略的EVPI从1550美元降至140美元,而药物相互作用策略的EVPI从1220美元降至280美元。因此,药物基因组学指导的华法林给药的证据水平似乎高于药物相互作用指导的华法林给药。这些发现可以为华法林PM的临床指南和报销政策提供信息。
Evidence requirements for implementation of precision medicine (PM), whether informed by genomic or clinical data, are not well defined. Evidence requirements are driven by uncertainty and its attendant consequences; these aspects can be quantified by a novel technique in health economics, value of information analysis (VOI). We utilized VOI analysis to compare the evidence levels over time for warfarin dosing based on pharmacogenomic- vs. amiodarone-warfarin drug-drug interaction information. The primary outcome was the expected value of perfect information (EVPI), which is an estimate of the upper limit of the societal value of conducting future research. Over the past decade, the EVPI for the pharmacogenomic strategy decreased from $1550 to $140 vs. $1220 to $280 per patient for the drug-interaction strategy. Evidence levels thus appear to be higher for pharmacogenomic-guided vs. drug interaction-guided warfarin dosing. Clinical guidelines and reimbursement policies for warfarin PM could be informed by these findings.
