逐步楔形分组随机设计在临床试验和实施科学研究中受到越来越多的关注。该设计的关键特征是在交错时间表上从控制到干预条件的群集的单向交叉,这引起了时间对干预效果的混淆。阶梯楔形设计首次出现在20世纪80年代的冈比亚肝炎研究中。然而,用于设计和分析的统计模型直到2007年才在Hussey和Hughes的一篇文章中正式介绍。从那时起,已经提出了各种混合效应模型扩展这些试验的设计和分析。在本文中,我们将在统一的视角下探索这些扩展。我们提供了一个通用的模型表示,并把各种模型的扩展作为替代方法来表征长期趋势,干预效果,以及异质性的来源。我们回顾了模型的主要成分,并阐明了它们对设计和分析的影响。这篇文章作为一个切入点,不断发展的统计文献阶梯楔形设计。
The stepped wedge cluster randomized design has received increasing attention in pragmatic clinical trials and implementation science research. The key feature of the design is the unidirectional crossover of clusters from the control to intervention conditions on a staggered schedule, which induces confounding of the intervention effect by time. The stepped wedge design first appeared in the Gambia hepatitis study in the 1980s. However, the statistical model used for the design and analysis was not formally introduced until 2007 in an article by Hussey and Hughes. Since then, a variety of mixed-effects model extensions have been proposed for the design and analysis of these trials. In this article, we explore these extensions under a unified perspective. We provide a general model representation and regard various model extensions as alternative ways to characterize the secular trend, intervention effect, as well as sources of heterogeneity. We review the key model ingredients and clarify their implications for the design and analysis. The article serves as an entry point to the evolving statistical literatures on stepped wedge designs.
