Summary

Complex Extension: Identifiers of medicine continuum: The identifier of the medicine in use and part identifier of medicine continuum. Status information 'Latest'. Source

  • medicineId: Identifier: Automatically produced by an information system, a technical OID identifier that combines the entries of the same prescribed drug.
  • medicineIdPart: positiveInt: Automatically produced by the information system. Separates the different continuums of the same drug (that is, simultaneously used prescriptions for the same drug). As a rule, the drug used has only one medicine continuum at a time (only one active prescription). When it is necessary to have two or more active prescriptions for a drug, for example, when the patient uses two different strengths of the drug, the medicine continuums are separated by the part identifier of the medicine continuum.
  • newest: boolean: Information maintained by the Kanta Prescription Centre on what is the latest prescription in the medicine continuum. The value True says that the prescription is the latest prescription in the continuum.
