Advancing the mission of medicine

Epividian is an independent research organization that provides healthcare analytics to clinics, hospitals, and practices nationwide

By developing novel technologies and empowering clinical practice, clinical research, academic, public health and regulatory efforts, we pursue our mission of solving complex problems to improve the health of individuals and the public.

Point-of-care observational data from the doctor-patient encounter is used to support real-world medical research and patient disease management.


The CHORUS service enhances the doctor-patient relationship by helping doctors spend more quality time with patients. CHORUS transforms your existing EHR data into new, meaningful information and actionable insights.

  • Better care with analytics and disease management for HIV, HCV and other chronic diseases
  • Improve patient outcomes with quality metrics and health scores that highlight gaps in care
  • Improve caregiver performance with anonymous OPERA benchmarking
  • Quickly identify patients for outreach and for studies
