Closing the Marketing Loop: Novant Health’s HIPAA-Safe Attribution Case Study

Most health systems run media budgets without knowing which campaigns drive actual booked appointments — this case study with Novant Health shows what’s possible when you close that loop. Cardinal Digital Marketing built a three-stage measurement maturity framework connecting Epic outcome data to ad platforms through Freshpaint, a HIPAA-compliant CDP that strips PII before activating conversion signals in Google Ads, Meta, and programmatic platforms. The result: new patient appointments grew 10% overall across supported service lines, with Bariatrics up 55%, Orthopedics up 30%, and OB/GYN up 10%. The framework’s core insight — feed algorithms booked appointments, not clicks — allowed ad spend to self-optimize toward real patient acquisition rather than downstream activity proxies.
