Overview
Versatile and reporting-ready, the Core Data Model is a hierarchical data structure that incorporates decades of experience turning data into answers, helping clients unlock the value in their data right away.
The Core Data Model has been carefully built to contain a wealth of information, yet only the information you truly need to support any healthcare use case. Our connectors clean and integrate source data—from claims, EMR, billing, and other systems—then enrich the data with reference material from across healthcare in preparation for synthesis. Instead of cleanup work, you’re starting with ready-to-use tables covering a wide range of useful concepts, from encounters and clinical episodes to provider attribution models and timelines of patient risk and disease status.
Disclaimer: "Measure Case" is now referred to as "Data Mart".
