The number of pilot and feasibility studies in the literature is increasing, but they are often poorly reported. Our research into pilot and feasibility studies aims to improve the conduct and reporting of such studies. Our methodological work in this area is listed below. The group leading this work has also facilitated a number of workshops on conducting pilot and feasibility studies. We also have collaborations with others working on pilot and feasibility studies both in the UK and Canada.

Specific topics of our work include: 

• A framework for defining pilot and feasibility studies focusing on studies conducted in preparation for a randomised controlled trial 
• A CONSORT extension for pilot and feasibility trials 
• A systematic review of the reporting quality of pilot and feasibility cluster randomised trials 
• A simulation study to see how large a pilot study for a cluster randomised trial should be
• A website designed to support those conducting pilot and feasibility studies and those carrying out methodological research on these types of studies https://pilotandfeasibilitystudies.qmul.ac.uk/
