Real-world Site Experiences With GeneMatch: The Role of a Recruitment-related Registry in the Context of Local Site Effort to Support Alzheimer Disease Prevention Research.

Background: Registries have been proposed as a novel way to accelerate targeted recruitment for Alzheimer disease prevention clinical trials. However, there are limited data regarding registry effectiveness at accelerating recruitment and enrollment in research opportunities. This manuscript explores one site's experience with GeneMatch, a novel genetic registry for Alzheimer disease research.

Methods: Referrals from GeneMatch to the site were tracked to understand the demographics of those referred and ultimate research enrollment outcomes. Referrals were cross-referenced with the site's existing recruitment database, to better understand the role of GeneMatch in the context of existing recruitment efforts.

Results: GeneMatch referred 86 individuals to the site, resulting in 54 individuals coming into the site to pursue research involvement further. The majority of referrals (52/86, 60.47%) did not have prior contact with the site about research engagement, and having prior site contact did not significantly relate to engaging in on-site research.

Conclusions: GeneMatch helped identify new individuals for participation in Alzheimer disease prevention studies. Results highlight the value of continuing local site-level efforts while also taking advantage of registries to enhance research recruitment. Ongoing efforts to further develop these and other novel strategies for outreach and engagement are much needed.
