Second International Conference on Stepped Wedge Trial Design

19 - 20 March 2018

Interest in research studies employing the incremental implementation and evaluation of an intervention (stepped wedge design) has continued to gather momentum.

We are therefore pleased to announce that on the back of the success of the first conference in 2016, the second international conference on the stepped wedge study design will be held in York. This event aims to bring together practitioners, researchers and methodologists to share ideas, experience, best practice and challenges for the design, implementation and analysis of the stepped wedge model. The conference will allow anyone interested in this design to stay at the forefront of knowledge about its methodology and application as well as connect with other experts in the field.

The conference is expanding in scope and will be held over two days Monday 19th and Tuesday 20th March 2018, in the Department of Health Sciences, University of York, UK. It is organised by Professor David Torgerson (York Trials Unit), Dr Mona Kanaan (York Trials Unit), Dr Noreen Mdege (Mental Health and Addiction Research Group) and Ada Keding (York Trials Unit).


A conference workshop will be held on the morning of the 19th of March. This will include a brief introduction to the stepped-wedge cluster randomised trial (SW-CRT), with two key and iconic examples. This will lead on to a systematic evaluation of when the SW-CRT is a justifiable alternative to the more common parallel cluster randomised trial; risks and barriers to trial success; and key design variants to consider. In the second half of the workshop we will consider means to determine sample size and power; and key considerations for the analysis. The workshop will end with top tips for trial set up and reporting. Interactive examples will be included throughout. The workshop will be run by Dr Karla Hemming and Dr Monica Taljaard.

In the afternoon, the conference itself will commence with a keynote address given by Dr Karla Hemming from the University of Birmingham, followed by invited presentations from national and international speakers on a range of aspects of the stepped wedge design. Posters on the subject will be displayed all day. The planning committee will award prizes for best contributed presentation and poster.
