How to calculate screen failure rate in clinical trials, why it runs high, and the funnel steps that cause it, with the levers that raise the screen pass rate before patients reach the site.
Recruitment is modeled as eight separate steps: answering the call, passing the phone pre-screen, booking a visit, showing up, medical records confirming eligibility, attending screening, passing screening, and enrolling. Each step has its own probability from the protocol's criteria and our own call and visit data, simulated 10,000 times.
Beyond the forecast, CT SCAN runs IRB-approved patient advertising, a US-based outreach team calls and pre-screens every lead, and qualified patients are booked into site visits. CTS-360™, our SMO of research sites trained and readied in our methodology, runs the forecast, advertising, outreach and sites as one program for sponsors and CROs.
