Alzheimer’s Trial Recruitment Sees Boost with Modest Incentives
Table of Contents
A small financial incentive-a $25 Amazon gift card-substantially increased enrollment in an Alzheimer’s disease patient registry designed to accelerate clinical trials, according to a recent study from the University of southern California. The findings offer actionable insights into improving representation in Alzheimer’s research, a critical area given the disproportionate impact of the disease on marginalized communities.
The Importance of Diverse Clinical Trials
Effective strategies are essential to enhance the inclusion of diverse populations in Alzheimer’s clinical trials. Researchers have debated the ethics of financial incentives for trial participation, with limited consensus on appropriate incentive levels. This study provides empirical data to inform that debate.
The alzheimer’s Prevention Trials (APT) initiative invited nearly 50,000 adults aged fifty and over, without existing dementia diagnoses, to join a registry. This registry aims to identify and monitor individuals at higher risk of developing Alzheimer’s, streamlining the recruitment process for future clinical trials. Participants received healthcare through an integrated county health system primarily serving Medicaid recipients.
Study Design and Methodology
Participants were randomly assigned to one of three groups. The control group received a standard invitation to register. A second group was offered a $25 Amazon gift card upon registration. The third group was entered into a lottery for a $2,500 Amazon gift card, with a 1 in 100 chance of winning.

Key Findings and Results
The $25 gift card offer resulted in a nearly 40% increase in registrations compared to the control group. The incentive proved particularly effective among White participants, men, and those enrolled in Medicaid.Surprisingly, the chance to win a larger prize did not significantly increase registration rates.
| Incentive Type | Registration Increase vs. Control Group |
|---|---|
| Control (Invitation Only) | Baseline |
| $25 Amazon Gift Card | ~40% |
| Lottery for $2,500 Amazon Gift Card | No Significant Increase |
While the small gift card significantly increased registrations,researchers found that a simple message-based approach was a more cost-effective strategy for enrolling low-income patients. investing in community outreach and awareness campaigns may ultimately be a more efficient use of resources for patient registry recruitment.
Pro Tip: building trust within communities is paramount for accomplished clinical trial recruitment. Partnering with local organizations and leaders can significantly improve participation rates.
Study Leadership and Funding
The study was led by Mireille Jacobson, co-director of the aging and cognition program at the USC Schaeffer Center and a professor at the USC Leonard Davis School of Gerontology, and Doris Molina-Henry, a Schaeffer scholar and assistant professor of research neurology at the alzheimer’s Therapeutic Research Institute (ATRI).
Published on August 22 in JAMA Health Forum, the research was conducted by the alzheimer’s Trial Recruitment Innovation Laboratory (ATRIL), a collaboration between the Schaeffer Center, ATRI, and Howard University.ATRIL aims to diversify participant recruitment in clinical trials and is funded by the American Heart Association. Additional support came from the Clinical Trials Recruitment Laboratory, funded by the Schaeffer Center and Gates Ventures. Full author disclosures are available in the published study.

Alzheimer’s Disease: A Growing Public Health Crisis
Alzheimer’s disease is a progressive neurodegenerative disorder that affects millions worldwide. The number of Americans living with Alzheimer’s is projected to nearly double by 2050, reaching 12.7 million, according to the Alzheimer’s Association. Alzheimer’s Association facts and Figures. Early detection and diverse clinical trials are crucial for developing effective treatments and improving patient outcomes. The current lack of diversity in clinical trials limits the generalizability of research findings and may exacerbate health disparities.
