In Epic reporting, what is the role of Clarity and Chronicles?

• A. Chronicles is the operational database with real-time data.
• B. Clarity stores imaging; Chronicles stores billing.
• C. Clarity and Chronicles are both clinical decision support systems.
• D. Clarity is the data warehouse for external reporting; Chronicles is the operational database with real-time data.

Answer: (D)

In Epic, two data environments serve different purposes. Chronicles is the real-time, transactional database that powers day-to-day operations—clinical workflows, orders, charts, scheduling, and billing as care happens. It holds current, writable data used by the live EHR. Clarity is a separate data warehouse built for reporting and analytics. It stores historical, curated data extracted from Chronicles (and other sources) to support external reporting, business intelligence, and long-term trend analysis. Because it’s optimized for queries, Clarity enables efficient reporting without impacting the live transactional system. Imaging data isn’t stored in Chronicles; it resides in imaging repositories. So the described roles—Clarity as the data warehouse for external reporting and Chronicles as the operational database with real-time data—best capture how Epic separates reporting from daily operations.
