A pilot randomized trial of five financial incentive strategies to increase study enrollment and retention rates.

ABSTRACT:

Background

Enrollment and retention difficulties remain major barriers to conducting clinical trials. Financial incentives may promote clinical trial enrollment, however delivery methods to maximize enrollment, maximize retention, and minimize cost remains uncertain.
