In health care messaging and healthcare generally it is vitally important that the correct test, procedure, report etc is done on the right patient and the results are consigned to the appropriate person. The use of identifiers plays a major role in ensuring clinical safety in messaging and the healthcare system.
The representation of healthcare identifiers used for patient, provider organisation and health identifiers in HL7 V2.x messages uses the common attributes of HL7 Table 0203 - Identifier Type and User-defined Table 0363 - Assigning Authority below.
