How to choose a patient recruitment company for your research site

By TrialNotice · Updated

Short answerChoose a patient recruitment company by asking how it finds patients, how it prescreens, what it charges for (leads, screens, randomizations, or a flat fee), how it reports results by source, and who owns the data. The deciding question is whether its patients actually randomize at sites like yours, because cheap leads that fail screening cost more than they save.

What types of recruitment companies are there?

  • Patient advertising firms run digital and media campaigns that send leads to the site.
  • Database and registry companies match studies against people who have opted in to hear about trials.
  • Physician referral outreach companies reach local physicians who already manage the study population.
  • Site networks bundle recruitment with site operations.

How do recruitment companies charge?

  • Per lead: easy to compare, but rewards volume over quality.
  • Per screen or per randomized patient: aligns payment with outcomes, often at a higher unit price.
  • Flat monthly fee: predictable, and puts the burden on you to measure results.

Whatever the model, convert it to cost per randomized patient. A meta analysis found online recruitment cheaper per enrollee but offline methods converted better in 69% of comparisons (JMIR). With average screen failure at 36.3% (Tufts CSDD), lead quality decides the real cost.

What should you ask before signing?

  1. Where exactly do your patients come from?
  2. How do you prescreen, and against which criteria?
  3. What is your screen failure and randomization rate on comparable studies?
  4. What do you report, how often, and by source?
  5. Who prepares patient facing materials, and who submits them to the IRB? FDA treats ads and flyers for prospective subjects as materials the IRB reviews (FDA).
  6. How is patient data handled, and who owns it after the study?
  7. Can we pilot on one study before committing?

What are the red flags?

  • Guaranteed enrollment numbers before the company has seen your protocol.
  • Recycled statistics with no source, such as the widely repeated $6,533 cost per patient. See what recruitment really costs.
  • Paying physicians for referrals. The AMA treats payment solely for referral as unethical fee splitting (AMA), and WCG IRB does not allow referral fees (WCG).
  • Reports with only lead counts and no screening or randomization data.

How do you judge results?

Track every patient from the vendor through screening and randomization, and count staff time. In one trial, recruitment took 3.7 staff hours per randomized patient (PMC), and poorly matched leads consume that time. See how to calculate recruitment ROI.

Physician referrals vs Facebook ads for clinical trial recruitment

Online ads tend to be cheaper per enrollee and faster, while offline channels convert better. Here is what the research says about ads versus referrals, and how sites use both.

Should a research site market to physicians or directly to patients?

The protocol decides the balance. Here is a framework for choosing between physician outreach and direct to patient marketing based on diagnosis requirements, criteria complexity, prevalence, and approvals.
