Randomized controlled trial as topicThe basic premise of a stepped wedge cluster randomised trial (SW-CRT) is that all clusters start in the control condition, and they switch to the intervention condition in an order determined by randomisation. SW-CRTs differ from cluster crossover trials in ...
The use of Stepped Wedge cluster randomized trials: Systematic Review Dr Celia Taylor The University of Birmingham On behalf of my co-authors: Noreen Mdege, Mei-See Man and David Torgerson (University of York) Today’s presentation What is a stepped wedge design? What are the advantages and...
In this section we examine a number of issues related to the design and analysis of stepped wedge CRTs. Discussion Using theoretical calculations and simulation we have investigated statistical characteristics of the stepped wedge design for cluster randomized trials. In particular, we have outlined a...

This is a cluster randomized trial.DISCUSSION:Integrating MISSION-Vet within HPACT has the potential to improve the health of thousands of veterans, but it is crucial to implement the intervention appropriately in order for it to succeed. The lessons learned in this protocol could assist with a ...

Stepped wedge cluster randomized controlled trials (RCTs) are increasingly used in evaluating a causal-effect relationship between an intervention and an outcome. Sample size and power calculations are critical in designing a statistical study. Thus, the purpose of our study is to evaluate the power...

To describe the application of the stepped wedge cluster randomized controlled trial (CRCT) design. Systematic review. We searched Medline, Embase, PsycINFO, HMIC, CINAHL, Cochrane Library, Web of Knowledge, and Current Controlled Trials Register for articles published up to January 2010. Stepped we...
Background: Stepped wedge cluster randomized trials are a class of unidirectional crossover studies that have historically been limited to evaluating a single intervention. This design is especially suitable for pragmatic trials where the study feasibility can be improved with a phased introduction...
