Find and Recruit the Participants You Need

Diverse group of older adults laughing and holding hands.

Recruiting participants who are a good match for your study isn’t always easy. If you have experienced recruitment challenges, you’re not alone—a surprising number of clinical studies at OHSU never enroll a single participant. In addition to traditional advertising and outreach through clinics, there are a variety of tools and resources that can help investigators identify potential participants. We have gathered documents, tools and information to help you as you plan and implement your study. 

Explore below to learn how OCTRI Recruitment connects with research teams to ensure they have the knowledge, tools, and support needed for successful participant recruitment and retention throughout their studies. 

It can be hard to know how to best recruit for your study goals and population. OCTRI Recruitment can help! Meet with our team for a complimentary recruitment consult to discuss your recruitment needs and goals and help you create a strategy tailored to your study.  To schedule a recruitment consultation, or for questions about the resources described here, please email

  • Trial Innovation Network: The Clinical and Translational Science Award program has established the Trial Innovation Network to assist investigators planning and conducting multi-site research.  

Clinical research has historically underrepresented and excluded certain populations. Individuals and groups have experienced this exclusionary behavior due to their race, ethnicity, age, sexual and/or gender identity, socio-economic status, development and disabilities, and geographic region. Our program, as a part of the NIH CTSA grant model titled “Integrating Special Populations” (ISP), works to change this.

OCTRI’s ISP team is invested in providing education and guidance to help research teams develop an inclusive and representative research plan, aligned with the demographics of the disease being studied, that is compliant with NIH policies and provides a good foundation for excellence in scientific progress. Our program has a special emphasis on inclusive research across the lifespan. Read more about the NIH policy on inclusion across the lifespan or peruse our Recruitment Resources and Guidance section below to learn more about including representative populations in research.
