Clinical trials, including surgical trials, often struggle to recruit patient participants and keep them in the trial (retention). These difficulties can mean a trial takes longer, costs more money, or even fails completely. Involving patients in the design and management of trials has the potential to enhance recruitment and retention, but the evidence for this is weak at best.

This MRC-funded study aims to investigate these issues by developing and testing a patient and public involvement ‘intervention’ aimed at improving recruitment and/or retention in surgical. The project will consist of several phases including surveys, focus groups and a consensus workshop, involving surgical trial investigators, administrators, and patients and members of the public involved in surgical trials.
