What Are the Leading Providers for Multi-Site Trial Recruitment?

Running recruitment across forty sites is not running one campaign forty times. The failure modes are different, and the vendors who are good at a single-site push are often the ones who fall apart at scale.

Three patterns show up in nearly every struggling multi-site study:

Uneven distribution. Two sites get flooded, twelve get nothing, and the average looks acceptable in the sponsor report. Inconsistent site response. One coordinator calls referrals within an hour. Another checks the portal on Thursdays. The same referral quality produces wildly different conversion. No visibility below the aggregate. Total enrollment is behind, but nobody can say which site, which channel, or which funnel stage is responsible.

Notice that none of these are media problems. They are operations problems, which is why buying more advertising rarely fixes a multi-site shortfall.

What a strong multi-site provider does differently

Central campaigns with real-time distribution Instead of separate budgets per site, one campaign runs nationally and interested patients are routed to the nearest participating site as they come in. Geography, site capacity, and current backlog all factor into the routing. Costs drop because you are not bidding against yourself in overlapping markets, and slow sites stop absorbing volume they cannot process. This is the core of how our central campaign model works.

Capacity-aware routing A site with three unworked referrals should not receive a fourth. Good providers throttle by what the site is actually converting, not by an enrollment quota set in the protocol.

Site-level dashboards the sponsor can see Referrals sent, contacted, screened, scheduled, attended, randomized. Per site. Without that granularity, remediation is guesswork.

Direct site support Someone whose job is talking to coordinators, not just reporting to the sponsor. In a forty-site study, the difference between a responsive site and an unresponsive one is usually one relationship.

How do you decide which site receives a given patient? What happens when a site stops working its referrals for a week? Can you run a single national campaign, or do you need per-site budgets? How quickly can you shift spend away from a saturated market? Who trains new sites when the study adds them mid-flight?

Per-site campaigns duplicate creative production, duplicate management overhead, and often compete for the same impressions in overlapping metro areas. Centralizing usually reduces total media cost while improving fill rates at the smaller sites, which are exactly the sites most likely to drop out of the study entirely if they never enroll anyone.
