Factsheets
Castor’s On-site ePRO lets site staff administer participant questionnaires in-clinic, without extra apps or device hassles.
Start from a site device, hand it to the participant, or display a QR code so they can continue on theirs. Need to pause, switch devices, or finish later? You can switch methods mid-questionnaire while progress is preserved, and an automatic backup link lets participants finish remotely if needed.
Our On-site ePRO is designed to reduce burden on sites without the reliance on hardware. For protocols that require in-clinic assessments, or situations where participants have limited access to—or comfort with—technology.
Castor’s On-site ePRO keeps it simple, it doesn’t require dedicated site apps or provisioned hardware. The result is smoother on-site workflows, higher submission flexibility, and more complete data capture—while staying aligned with the compliance and convenience of remote ePRO. Castor has supported 5,200 ePRO studies with 149M+ questionnaire datapoints, and typical deployments go live in 6–8 weeks.
