Case Study: Southeastern Nephrology Associates achieves streamlined, secure participant payments with Greenphire ClinCard

SENA Incorporates Participant Payment Automation to Improve Clinical Trial Operations

Southeastern Nephrology Associates (SENA), a nephrology practice conducting clinical research since 1975, faced an inefficient participant payment process: manual checks routed through the main office requiring Medical Director sign-off (taking up to two weeks), split tracking across departments, and no clear accountability. With roughly 10 new participants enrolled monthly and 2–3 payments per participant each month, the workflow was time-consuming, error-prone, and unsustainable for ongoing research operations.

SENA implemented Greenphire’s ClinCard, onboarding within a week with “no learning curve,” to centralize payments and reporting. The solution eliminated check cutting and mailing, gave coordinators a single portal for payments and participant setup, delivered instant reloadable debit card payments to participants, and improved financial transparency for SENA and its Sponsor. The streamlined process freed staff time for patient care, increased sponsor confidence, and positioned SENA to expand ClinCard usage across additional studies and users.
