The patient Identity subject is an identity subject that identifies a patient.
Patient subjects have the following attributes:
Subject Label | “Patient” |
Subject type | Identity |
Synchronization | Constant |
Security | None |
Subject Dependencies | None |
Mapping Agent Coupon Value | -1 |
A patient can be identified using different identifiers by different applications at a site. For example, different applications may use application-specific medical record numbers to identify the same patient. Site-defined suffixes of subject identifier items identify the patient in different applications. A Patient-Link-enabled application should be configurable to use the appropriate suffix (or suffixes) when getting or setting context data.
Patient subjects have the following standard context data items. A Patient Linked application should set the value for at least one of the items listed in the following table:
Patient Subject Identifier Item Name | Meaning | Data Type | Semantic Constraints on Values | Case Sensitivity |
---|---|---|---|---|
Patient.Id.MRN.Suffix | Patient's medical record number, per PID-2 | ST | HL7 Table 0203 Identifier Type = MR | No |
Patient.Id.MPI | Patient's identifier in the “Master Patient Index”, per PID-2 | ST | HL7 Table 0203 Identifier Type = PT or PI (as agreed upon by context sharing systems) and Assigning Authority represents the MPI system | No |
Patient.Id.NationalIdNumber | Patient's national identifier number, per PID-2 | ST | HL7 Table 0203 Identifier Type = PT and Assigning Authority represents agreed upon National Authority | No |
Patient.Id.IdList | A list of patient identifiers for a patient, per PID-3 | CX | May be a repeating set of CX item values, each of which contains one identifier that denotes the same patient (Driver's license and social security number may be among these identifiers) | No |
An application can optionally set values for the corroborating items listed in the following table:
Patient Subject Corroborating Item Name | Meaning | Data Type | Semantic Constraints on Values | Case Sensitivity |
---|---|---|---|---|
Patient.Co.PatientName | Patient's legal name, per PID-5 | XPN | Table 0200 | No |
Patient.Co.AliasName | Alias name for the patient, per PID-9 | XPN | Table 0200 | No |
Patient.Co.DateTimeOfBirth | Patient's Date and time of birth, per PID-7 | TS | None | No |
Patient.Co.Sex | Patient's gender, per PID-8 | IS | Table 0001 | No |
Patient.Co.DLN | Patient's driver's license number, per PID-20 | DLN | None | No |
Patient.Co.SSN | Patient's Social Security Number, per PID-19 | ST | None | No |
