Patient (When used in the context of ATNA) RFC-XXXX defines the means of identifying the person who is a patient. The patient information in audit event records corresponds to the information available to identify a patient at the time the audit record was generated, and does not reflect later up- dates (e.g. patient reconciliation).
PatientID (When used in the context of ATNA) A free text that holds the system- internal patient identifier being unique within that system domain. The patient identifier domain is that assigned to the system that generated the audit event record. The patient information in audit event records corres- ponds to the information available to identify a patient at the time the audit record was generated, and does not reflect later updates (e.g. patient reconciliation).
Patient Identifier Cross-reference Domain Consists of a set of Patient Identifier Domains known and managed by a Patient Identifier Cross-reference Manager Actor. The Patient Identifier Cross-reference Manager Actor is responsi- ble for providing lists of alias identifiers from different Patient Identifier Domains.
Patient Identifier Domain A single system or a set of interconnected systems that all share a common identification scheme for patients. Such a scheme includes: (1) a sin- gle identifier-issuing authority, (2) an assignment process of an identifier to a patient, (3) a permanent record of issued patient identifiers with associated traits, and (4) a mainte- nance process over time. The goal of Patient Identification is to reduce errors.
