What is the role of identity matching services within EpicCare Everywhere?

• A. They provide encryption for data in transit.
• B. They generate patient IDs locally.
• C. They help link patient records across organizations by matching identities.
• D. They sequence messages between servers.

Answer: (C)

Identity matching services in EpicCare Everywhere act as the bridge that connects patient records from different organizations by determining when separate records actually belong to the same person. They use patient demographics (such as name variations, date of birth, gender, and address) and existing identifiers to assess whether two records refer to the same patient. Through deterministic and probabilistic matching, they create a unified patient identity across partner sites, enabling clinicians to view a complete, longitudinal record even when the data comes from multiple organizations. This helps reduce duplicates and ensures the right chart is opened for the right patient during cross-organization care. It is not about encrypting data in transit, generating local patient IDs, or sequencing messages between servers.
