Understanding the Clinical Trial Eligibility Funnel
A clinical trial referral does not move directly from interest to randomization. It passes through several stages, creating an eligibility funnel. The process usually starts with an external referral, followed by site pre-screening, a screening visit, informed consent, eligibility confirmation, and finally randomization. Each stage can influence how many candidates continue.
Tracking only referral numbers can hide where candidates are being lost. Stage-level tracking helps research teams understand whether challenges are related to referral quality, missing information, screening requirements, or operational delays. DecenTrialz supports the earlier part of this workflow through structured study matching and nurse-led pre-screening, while research sites retain responsibility for formal screening and eligibility decisions.
