Description
Many health trials struggle to sign up enough people, which can waste funds and leave key questions unanswered. Adwoa Parker and co-authors update a large 2026 review of what actually helps trials recruit more participants.
The review gathers small trials run inside larger ones, each testing a single sign-up tactic, such as a changed letter or a reminder. The team searched eight data sources up to early 2023 and weighed cost, fairness, and whether new recruits stayed in the trial. Earlier editions of the review shaped how trial teams plan outreach. This update gives trial staff a fresh, evidence-based guide to which tactics are worth their time and money.
