Each participating institution runs the CareEvolution Adapter Service that provides the interface between the Record Locator Service, peer institutions, and the institution’s local clinical data sources.

The CareEvolution adapter is composed the following distinct components:

Record Index Service - The Record Index Service provides the interface between the host systems and the Record Locator Service. It standardizes and blinds demographic information before sending requests to the Record Locator Service.

Data Transfer Service - The Data Transfer Service manages adapter to adapter (peer to peer) communication of clinical information.

Clinical Data Interface Service (CDIS) - The CDIS hosts a set of pluggable drivers for communication with an institution’s local clinical data sources such as EMR, lab, or pharmacy systems. The CDIS allows for easy customization to support the disparate clinical data sources of each institution. Terminology Service - The Terminology Service is used by the Data Transfer Service and CDIS to provide translation between local and UMLS standard terms.

Local Data Cache - The Local Data Cache provides a data store in which both record location index information and clinical information is cached.
