We design and deliver studies that explore participants' and researchers' experiences of many aspects of RCTs across a range of clinical areas and using a range of different methodologies.  Some of these studies have been primary qualitative studies (using interviews, focus groups and non-participant observations) that have explored the following:

  • patients experiences of the recruitment process;
  • patients experiences of retention in trials;
  • stakeholders (patients, trialists, research nurses, trial managers, ethics committee members) perceptions of how best to support informed decisions about trial participation and what outcomes matter for evaluation;
  • development of measures of decision quality for RCT informed consent;
  • trial site staff’s (consultants and research nurses) experiences of recruiting to RCTs;
  • surgeons and methodologists perceptions and beliefs about expertise based RCTs;
  • stakeholders’ beliefs and perceptions of placebo controlled surgery.

In addition to primary studies, we have also delivered a number of syntheses of qualitative studies exploring participant reported reasons for trial participation or drop-out.

Work in this area is actively ongoing across the portfolio of RCTs.
