Which statement is true about which dates can slide in Epic?

• A. All dates slide
• B. Only birth dates slide
• C. Only appointment dates slide
• D. Only dates captured in discrete date fields in Epic will slide

Answer: (D)

Date shifting in Epic applies only to fields that store a real calendar date as a discrete value. The system offsets those dates by a consistent random amount within a defined window, so the relative timing between events for the same patient stays plausible while the exact dates are obscured. Dates that aren’t stored as discrete date fields—such as dates embedded in free text, partial dates, or values calculated from other data—aren’t shifted. That’s why the correct statement is that only dates captured in discrete date fields in Epic will slide.
