Founda offers a secure and fast **Patient Identifier Cross-Reference Manager **to help healthcare providers with their cross-referencing challenges. 

:::hint{type="info"}
**When to use:**
An example scenario in which the cross-reference manager can be useful is when there are different patient identifiers across different systems. Let's say a patient is registered in the hospital's system with identifier *123*, but in a questionnaire application with identifier *abc*. Based on a set of similar patient demographics, the Founda Health Platform will store a mapping from identifier *123* to identifier *abc*, this way both systems can use their own identifiers for identifying the same patient.

The interaction consists of two parts:

1. First a Patient Identity Feed is created, consisting of patient identifiers that are cross-referenced across multiple systems. It's also possible to revise, remove or resolve duplicate identifiers. 
2. Once there is a mapping of patient identifiers, it can be used to retrieve the identifier needed by querying the patient identifiers from Founda's Patient Identifier Cross-Reference Manager.
