Patient Recruitment & Retention

Recruitment Powered by Primary Care. Retention Built on Trust.

Recruitment Powered by Primary Care. Retention Built on Trust.

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 underrepresented and high-burden 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.

Empowering clinicians to become research-active is not just about advancing science — it’s about transforming care at its core

How We Retain Participants

Local Trial Visits
Most study appointments take place at the patient’s GP practice, reducing travel and disruption to daily life.

Flexible Scheduling & Follow-Up
We offer appointment reminders, rescheduling options, and hybrid visit formats to support continued engagement.

Dedicated Research Support
Our site teams provide clear communication, follow-up care, and a familiar, welcoming environment throughout the trial.
