What patient recruitment & retention platforms do
Patient recruitment and retention organisations help trials find, screen, refer, enrol, and keep participants engaged. They may run patient communities, outreach campaigns, prescreening forms, referral pathways, call centres, or follow-up support.
Psychedelic trials often need narrow patient groups, careful exclusion screening, and steady engagement through preparation, dosing, integration, and follow-up visits. Recruitment partners are useful when they connect interested patients to sites without blurring advertising, consent, privacy, or eligibility boundaries.
Questions to ask
- Which patient groups or indications does the organisation show evidence of reaching?
- How does it handle prescreening, referral, retention, and handoff to trial sites?
- Are privacy, consent, and data-handling practices clear enough for regulated research?
Signals we track
- patient community reach
- screening and prequalification
- retention support
- privacy or compliance signal
- site referral model
