This manuscript presents a comprehensive framework for the assessment of the value of real-world evidence (RWE) in healthcare decision-making. While RWE has been proposed to overcome some limitations of traditional, one-off studies, no systematic framework exists to measure if RWE actually lowers the burden. This framework aims to fill that gap by providing conceptual approaches for evaluating the time and cost efficiencies of RWE, thus guiding strategic investments in RWE infrastructure.
The framework consists of four components: (114th Congress. 21st Century Cures Act.; 2015. https://www.congress.gov/114/plaws/publ255/PLAW-114publ255.pdf .) identification of stakeholders using and producing RWE, (National Health Council. Glossary of Patient Engagement Terms. Published 2019. Accessed May 18. 2021. https://nationalhealthcouncil.org/glossary-of-patient-engagement-terms/ .) understanding value propositions on how RWE can benefit stakeholders, (Center for Drug Evaluation and Research. CDER Patient-Focused Drug Development. U.S. Food & Drug Administration.) defining key performance indicators (KPIs), and (U.S. Department of Health and Human Services - Food and Drug Administration: Center for Devices and Radiological Health and Center for Biologics Evaluation and Research. Use of Real-World Evidence to Support Regulatory Decision-Making for Medical Devices - Guidance for Industry and Food and Drug Administration Staff. 2017. http://www.fda.gov/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guida .) establishing metrics and case studies to assess value. KPIs are categorized as 'better, faster, or cheaper" as an indicator of value: better focusing on high-quality actionable evidence; 'faster,' denoting time-saving in evidence generation, and 'cheaper,' emphasizing cost-efficiency decision compared to methodologies that do not involve data routinely collected in clinical practice. Metrics and relevant case studies are tailored based on stakeholder value propositions and selected KPIs that can be used to assess what value has been created by using RWE compared to traditional evidence-generation approaches and comparing different RWE sources.
Operationalized through metrics and case studies drawn from the literature, the value of RWE is documented as improving treatment effect heterogeneity evaluation, expanding medical product labels, and expediting post-market compliance. RWE is also shown to reduce the cost and time required to produce evidence compared to traditional one-off approaches. An original example of a metric that measures the time saved by RWE methods to detect a signal of a product failure was presented based on analysis of the National Cardiovascular Disease Registry.
The framework presented in this manuscript offers a comprehensive approach for evaluating the value of RWE, applicable to all stakeholders engaged in leveraging RWE for healthcare decision-making. Through the proposed metrics and illustrated case studies, valuable insights are provided into the heightened efficiency, cost-effectiveness, and improved decision-making within clinical and regulatory domains facilitated by RWE. While this framework is primarily focused on medical devices, it could potentially inform the determination of RWE value in other medical products. By discerning the variations in cost, time, and data utility among various evidence-generation methods, stakeholders are empowered to invest strategically in RWE infrastructure and shape future research endeavors.
本文提出了一个综合框架,用于评估真实世界证据(RWE)在医疗决策中的价值。虽然 RWE 被提议用于克服传统一次性研究的一些局限性,但目前还没有系统的框架来衡量 RWE 是否确实降低了负担。该框架旨在通过为评估 RWE 的时间和成本效率提供概念方法来填补这一空白,从而指导对 RWE 基础设施的战略投资。
该框架由四个部分组成:(114 届国会。21 世纪治愈法案;2015 年。https://www.congress.gov/114/plaws/publ255/PLAW-114publ255.pdf。)确定使用和产生 RWE 的利益相关者,(国家卫生理事会。患者参与术语词汇表。发布于 2019 年。访问于 2021 年 5 月 18 日。https://nationalhealthcouncil.org/glossary-of-patient-engagement-terms/。)理解 RWE 如何使利益相关者受益的价值主张,(药品评价和研究中心。CDER 以患者为中心的药物开发。美国食品药品监督管理局)定义关键绩效指标(KPIs),(美国卫生与公众服务部 - 食品和药物管理局:医疗器械中心和生物制品评估与研究中心。使用真实世界证据支持医疗器械监管决策 - 行业和食品药品监督管理局工作人员指南。2017 年。http://www.fda.gov/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guida。)建立评估价值的指标和案例研究。KPI 分为“更好、更快或更便宜”,作为价值的指标:更好地关注高质量可操作证据;“更快”表示在证据生成中节省时间,“更便宜”表示与不涉及临床实践中常规收集的数据的方法相比,决策成本效益更高。指标和相关案例研究根据利益相关者的价值主张和选定的 KPI 进行定制,这些 KPI 可用于评估使用 RWE 与传统证据生成方法相比创造了哪些价值,并比较不同的 RWE 来源。
通过从文献中提取的指标和案例研究进行了实施,记录了 RWE 的价值在于改善治疗效果异质性评估、扩大医疗产品标签和加快上市后合规性。与传统的一次性方法相比,RWE 还显示出降低证据生成成本和所需时间的优势。根据对国家心血管疾病登记处的分析,提出了一种衡量 RWE 方法节省时间以检测产品故障信号的指标的原始示例。
本文提出的框架提供了一种全面的方法来评估 RWE 的价值,适用于所有参与利用 RWE 进行医疗决策的利益相关者。通过提出的指标和案例研究,为临床和监管领域内提高效率、成本效益和改进决策提供了有价值的见解。虽然该框架主要侧重于医疗器械,但它有可能为其他医疗产品中 RWE 价值的确定提供信息。通过辨别各种证据生成方法之间的成本、时间和数据效用差异,利益相关者能够战略性地投资 RWE 基础设施并塑造未来的研究工作。
