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 stepped wedge RCT was chosen to be the best study design for evaluating the shift from old to new diagnostic criteria of GDM in Sweden. The national quality registers provide data on the whole pregnant population and gives a possibility for follow up studies of both mother and child. The...
This was a pilot feasibility stepped-wedge RCT which invited 26 GP practices in Bristol, South Gloucestershire and North Somerset with high practice population HIV diagnosed prevalence (> 2 per 1000) to take part. Practices that agreed to take part were randomised to either the intervention arm...
In a stepped wedge, cluster randomised trial, clusters receive the intervention at different time points, and the order in which they received it is randomised. Previous systematic reviews of stepped wedge trials have documented a steady rise in their use between 1987 and 2010, which was attribute...

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...
