Orizzonte leverages GP-patient relationships to drive effective, ethical recruitment and sustained participation. By engaging patients through their own GP practices, we increase enrolment speed and reduce dropout, especially in underserved populations.
How We Recruit
EMIS & SystemOne Database Searches
We conduct secure, protocol-specific searches using GP clinical systems to identify eligible patients in real time.
GP-Endorsed Outreach
Patients are invited by their own GPs through letters, SMS, or in-person discussion, creating a trusted pathway into research.
Targeted, Inclusive Strategies
We actively engage underserved communities by partnering with diverse GP practices across urban, rural, and multi-ethnic regions.
