The BEWS can use the method PatientUpdate to update the BESPID for a patient. The BEWS can also update a Patient with a blank BESPID, meaning that the current Noah Patient is no longer tied to the BESPID (In case of mistaken resolve process or Patient matching).

There can only be one Patient with a BESPID in the Noah database. It should be rejected if there is a request to update another Patient with an already existing BESPID.
