Are patients and public members involved in clinical trial oversight, or just ticking a box?

What is it about?

Patient and public involvement (PPI) in clinical research is now a widely promoted principle, and trial oversight committees — including Trial Steering Committees (TSCs) and Data Monitoring Committees — are increasingly expected to include lay members. This ethnographic study examined how PPI actually functions in practice within the oversight of eight UK clinical trials that were facing challenges in their conduct. Researchers observed oversight committee meetings and conducted semi-structured interviews with TSC and Trial Management Group members, including public contributors, trial sponsors and funders. The study explored how public contributors understood their role, how they interacted with professional committee members, whether their contributions were genuinely integrated into decision-making, and what enabled or hindered meaningful PPI. The findings identify the conditions under which PPI in trial oversight moves beyond tokenism and provide practical recommendations for optimising public involvement in future trials.

Why is it important?

Despite international policy mandates and growing investment in PPI initiatives, evidence on how public involvement actually operates within the specific context of trial oversight remains thin. Tokenistic PPI — where public contributors are present but marginalised — risks undermining both the quality of research governance and the trust of the public in clinical trials. This study, conducted by with partners across the MRC's trials methodology research network, provides rare ethnographic evidence from inside the governance structures of real trials, capturing dynamics that surveys and self-report methods cannot reach. Its practical recommendations address a gap in guidance for trialists, sponsors and research funders seeking to move from performative to substantive public involvement in trial oversight. The work sits within a broader programme of trials methodology research examining how oversight committees function, including in trials under stress.
