Clinical Medicine Insights: Pediatrics

Background: Literature reviews have identified recruitment as the single most challenging obstacle in conducting pediatric trials. This paper describes a paradigm shift in recruitment design, developed from experience with grassroots campaigns through the DRINK study (Decreasing the Rates of Illness in Kids). The objective of this study was to explain a new method for recruiting in clinical trials based on lessons learned from grassroots political campaigning.

Methods and findings: The study described is a randomized controlled trial of 638 3–6 year olds from the Washington, DC Area. The design involved a comparison between new recruiting approaches modeled after grassroots campaigns and traditional techniques. Traditional techniques for the purpose of this paper are defined by the use of physician referral, mass media such as radio and television advertisements, along with posters in public places like the subway. Grassroots approaches alternatively developed and utilized community contacts and employed targeted small market media community. The main outcome measures were the percentage of budget used and the number of eligible participants recruited.

Conclusions: The results showed that the grassroots recruitment approach saved 30% of the budget, recruited 638 kids in 4 months and retained over 90% for the 90 day trial. New techniques need further exploration as community studies are stressed.
