Methods Comprehensive literature review of studies or protocols using a stepped wedge design. Data were extracted from the studies in three categories for subsequent consideration: study information (epidemiology, intervention, number of participants), reasons for using a stepped wedge design and methods ...
答案是:阶梯设计(the stepped-wedge design) 阶梯设计多用于整群随机试验,评价“利大于弊”的干预措施,尤其在健康教育、免疫接种、筛检、医护人员培训等领域使用较多。这种设计通常不设置专门的对照组,随着试验的进行,各个组都会按照随机结果先后接受这种干预措施。这样就...

The study design consists of a hybrid before-and-after and stepped wedge trial design. The stepped wedge component enables us to make cross-sectional comparisons as well as within-site comparisons; the before-and-after component allows us to completely adjust for seasonal effects and evaluate the...
The CORE study protocol: a stepped wedge cluster randomised controlled trial to test a co-design technique to optimise psychosocial recovery outcomes for p... INTRODUCTION: User engagement in mental health service design is heralded as integral to health systems quality and performance, but does enga...
The analysis of data from such a design involves the comparison of the intervention “wedge” (i.e., data from the clusters that have received the intervention during a step) with the control wedge... ... Access to the complete content on Oxford Reference requires a subscription or purchas...
Stepped wedge design (SWD) is a cluster randomized controlled trial (RCT) design that sequentially rolls out intervention to all clusters at varying time points. Being a relatively new design method, reporting quality has yet to be explored, and this review will seek to fill this gap in knowle...
We identified key design choices and developed guidance for each.We identified three main stepped wedge designs: those with a closed cohort, an open cohort, and a continuous recruitment short exposure design. In the first two designs, many individuals experience both control and intervention ...
This design is especially suitable for pragmatic trials where the study feasibility can be improved with a phased introduction of the intervention. We examined variations of stepped wedge designs that would support evaluation of multiple interventions. Methods: We propose four different design varian...
Methods and design This study is a five-year stepped-wedge cluster-randomised trial. The intervention is the Saving Babies’ Lives (SBL) programme, which comprises two major components: participatory learning and action with CHWs, and capacity building of primary care facilities. The control is sta...
