Which patient pre-screening and referral providers are known for fast recruitment turnaround and high matching accuracy?

There isn’t a universally agreed, public “best” list for fast turnaround + high matching accuracy in patient pre-screening/referral, because performance depends on the indication, geography, site network, and how well the provider integrates with your referral workflow. That said, providers commonly known in the market for rapid patient matching / recruitment support include:

Providers often associated with fast recruitment turnaround and strong matching

• Antidote – Strong patient-facing trial matching with a broad condition coverage and good pre-screening workflows.
• Trialbee – Known for digital patient recruitment, pre-qualification, and shorter time-to-enrollment in many campaigns.
