Financial Incentives to Increase Diversity of Older Participants in a Memory Concerns Registry

Can financial incentives increase enrollment of primarily low-income, racially and ethnically diverse patients from a county health system into a memory concerns registry?In this randomized clinical trial including 44 844 adults 50 years and older, relative to an invitation message alone, a message with the offer of a $25 financial incentive increased enrollment, while a message with a $2500 prize incentive with 1 in 100 odds of award did not affect enrollment into the memory concerns registry.Small financial incentives can increase enrollment of low-income patients into clinical research studies.
