Participant Recruitment & Retention

Participant Recruitment, Done Right

Recruit the right participants and keep them engaged through study completion, with participant-first strategies that hit your enrollment goals and keep your trial on time and on budget.

Recruitment delays are remarkably common and costly: according to Clinical Leader, nearly 80% of participant recruitment timelines in clinical trials are not met, and over 50% of participants are not enrolled within the planned time frame. Some studies suggest each day of clinical trial setback can cost a sponsor $1 million in expected sales.

Getting participants enrolled is only half the challenge. Making study participants feel valued throughout their entire clinical trial journey is essential for study success, and it's equally important to give site staff the tools they need to keep themselves and their patients engaged for the duration of the study. After years of experience, Veristat has identified the key pitfalls, considerations, and solutions that carry a trial from first enrollment through study completion.

Participant recruitment gets a trial started, but retention is what gets it finished.
Participant-Centric Recruitment

Focusing on consumers as well as science has had the most measurable effect on Veristat's participant recruitment success. Participant-centric advertising, including branded study websites powered by strong marketing and SEO strategies, improves recruitment success in a cost-effective way. Today's participants are tech-savvy, proactive healthcare consumers and nearly half find out about clinical trials through media and the internet. Veristat builds its recruitment approach around that reality, not around outdated assumptions about how participants search for care.

Physician-Staffed Retention Support

Retention isn't an afterthought; it's essential to keeping a trial on time and on budget. Veristat's in-house call center is staffed by domestic and foreign-trained doctors with knowledge of the disease state and standard of care. The same team that helps qualify participants during recruitment also speaks directly with enrolled participants about the protocol and study activities, answers questions, addresses concerns, and identifies issues that could affect continued participation.

How It Works

Veristat's approach centers on three connected strategies that carry a study from first contact through study completion:

Participant-centric recruitment.

Branded, digitally-driven outreach that meets participants where they already search for care.

 

An in-house call center.

Physician-staffed support that qualifies participants during recruitment, then stays engaged with them through the life of the study.

 

Site engagement and study branding.

Tools, training, and consistent branding that keep site staff effective and participants engaged until study completion.


 

Veristat's Expertise

Here's what sets Veristat's recruitment and retention approach apart:

A full-service CRO should bring more than functions and resources. It should bring experience that improves decisions throughout development.

Consumer-first, not just science-first.

We build participant recruitment around how real people actually search for and decide on clinical trial participation.

Container-1-1
A full digital toolkit.

Digital media campaigns, social media, study apps, and targeted websites meet participants where they already are.

Container-3-1
Physician-staffed call center support.

Our in-house call center, staffed by domestic and foreign-trained doctors rather than generalist call agents, supports participants from pre-screening through the end of the study, giving them real, informed answers about their protocol and study activities.

Site partnerships built to last.

No two sites or studies are the same, so we customize our site engagement strategy and tools for each one, treating every site relationship as a long-term partnership.

Branding that drives response.

Memorable, consistent study branding across every touchpoint increases participant awareness and response, keeping both enrollment and retention on track.
