Introducing the new CONSORT extension for stepped-wedge cluster randomised trials

Karla Hemming, Monica Taljaard, Jeremy Grimshaw, Karla Hemming, Monica Taljaard, Jeremy Grimshaw

Abstract

The use of the stepped-wedge cluster randomised trial (SW-CRT) is on the increase, and although there are still relatively few SW-CRTs currently published its use is bound to show an increase in the near future. An extension of the CONSORT reporting guideline for SW-CRTs has recently been developed. By making reporting guidelines for this innovative design available relatively early in its development, it is possible that the methodological conduct and reporting of future SW-CRTs will not be at the same risk of low-quality of reporting as is the case with many other study designs. We provide a brief overview of this reporting guideline and encourage authors to use it appropriately; and for journal editors to endorse its use.
