This page contains several "recipes" that you can use to quick start your MPI deployment.
You can generate a new unique identifier for any patient (or other entity for that matter) registered in the SanteMPI solution, regardless of where the registration request originated from (HL7, FHIR, API, UI, etc.).
You can correct addresses being stored in the SanteMPI instance and/or append codified information to the address whenever a registration or update occurs.
If you're using the disconnected gateway you can write a business rule which will add a relationship to any data configured in the system or facility. You might want to do this, for example, if you're tracking where a patient's "home facility" is.
