A BMJ research article adds weight to the case for patient and public involvement in clinical trials, indicating that it is likely to improve enrolment of participants, especially if it includes people with lived experience of the health condition under study.

Over the past 10 years, the international literature evaluating Patient and Public Involvement (PPI) has more than tripled. The recent systematic review by Cocker and colleagues focusing on PPI’s effect on enrolment and retention in clinical trials is an important addition. Their review suggests that PPI can improve rates of enrolment in clinical trials. The finding is important because recruitment difficulties can reduce trial validity, add costs, and increase the risk of studies being abandoned and not reported.
