Good healthcare requires good evidence

Good randomized controlled trials (RCTs) provide reliable evidence that enables informed changes in healthcare practice. It must be made easier to do good RCTs to inform future care. 

The Good Clinical Trials Collaborative was set up to develop guidance to promote and enable good RCTs.

Our formal consultation process is over, thank you to those who have provided feedback. We are currently reviewing responses and are commencing revisions of the final guidance text. If you have particular comments please do send in to and we will consider those as we now move towards finalisation of the guidance.
