Patient-recruitment vendors, SMOs, and site networks
Referral Quality & Pre-Screen Filtration
We screen your inbound referral flow against the protocol before it reaches a site, and return a qualified or disqualified determination with the specific criterion that failed.
The problem
The number that ends most recruitment-vendor renewals is not cost per referral. It is what the site says about the referrals.
52% of sites report that at least one in five referrals is ineligible before formal screening, and 59% report enrolling fewer eligible patients because of recruitment-process inefficiency.
Provider-sourced referrals randomise at roughly 30.3%; paid-social self-referrals at roughly 4.3%. When you buy volume you buy the 4.3%, and you hand the cleanup to a coordinator who bills at a fully loaded rate and has no spare hours.
What you get
Screening of your inbound referral flow against the protocol’s inclusion and exclusion criteria before it reaches a site.
Per referral, a qualified or disqualified determination with the specific criterion that failed. Not a score — a reason.
A structured record of why a channel is failing, which is the input needed to fix the channel rather than replace it. When 40% of disqualifications on a protocol trace to one criterion, that is a protocol conversation you are then equipped to have.
How it is priced, and why
A fixed monthly retainer set by capacity tier, agreed in advance, under a written one-year agreement with a documented fair-market-value basis. It is never priced per referral screened, qualified, or enrolled — not at any volume, and not for any customer.

What this is not
Corterve does not determine whether anyone is eligible for a study, does not provide medical care, and does not promise that any particular number of people will be screened or enrolled. Those decisions belong to the study team under the protocol. We do not price any part of this work per referral, per candidate, or per enrolment.
