CPMC Clinical Information System Architecture

The components of the Clinical Information System are organized as central hub that enables clinical systems on disparate platforms to share patient data. The hub consists of a series of concentric layers that handle requests from client applications to either store or retrieve data:

• Message Handling Layer recieves these requests, and ensures that a reply is returned to the client system.
• Translation Layer maps data elements being stored in the system into a standard representation.
• Routing Layer connects clinical applications with central services that access data, and also propagates data from one application to another.
• Monitoring Layer triggers logic that evaluates the patient record according to specified criteria.
• Access Layer carries out the storage and retrieval transactions against the Clinical Repository, the central collection of all patient data in the institution.
