Patient Identifier Graph Model

Run the Patient Identifier Graph Model MicroSim Fullscreen

About This MicroSim

This model shows how a master patient index links the many identifiers a single person accumulates across healthcare systems. One patient record connects via HAS_IDENTIFIER to a hospital MRN, a second hospital's MRN, a Social Security number, and an insurance member ID; each identifier in turn is ISSUED_BY a different identity system. Resolving all these identifiers to one patient — record linkage — is a classic graph problem that prevents duplicate and fragmented records.

How to Use

Start at the central patient node and follow the HAS_IDENTIFIER edges out to each identifier, then the ISSUED_BY edges to the system that assigned it. Notice that the same person holds two different medical-record numbers from two hospitals — the kind of fragmentation a master patient index must reconcile. Drag nodes and use the navigation buttons to rearrange the radial layout.
