About the ePrescribing Subsets

Terminology Gateway


About the PrescribeIT® Subsets

Canada Health Infoway is working with Health Canada, the provinces and territories, and industry stakeholders to create, operate and maintain a financially self-sustaining, multi-jurisdiction e-prescribing service, known as PrescribeIT®. This will be a single service that can be scaled for use across the country enabling prescribers to electronically transmit a prescription to a patient’s pharmacy of choice.

The pan-Canadian PrescribeIT™

The pan-canadian e-Prescribing

subsets provide a standardized way for systems to capture, store, retrieve and transmit related health information. 

Implementation of the e-Prescribing subsets will allow the community based prescribers (such as physicians and nurse practitioners), either through their existing electronic medical records (EMR) or standalone applications, to enable the electronic transmission of prescriptions to community retail pharmacies.

Version numbers for EMR vendor specification, PMS vendor specifications and FHIR specifications follow the versioning convention of using   X.Y.Z (e.g. 2.0.1) where X is incremented when there is a major release, Y is incremented when there is a minor release and Z is incremented when there is a patch.

A major release is defined as any change that is not backwards compatible, a minor release is defined as a change to add new functionality that results in a change to the messaging interface and a patch is defined as a change that does not result in a change to the messaging interface.

The PrescribeIT® subset PrescriptionMedicinalProduct is based on the Canadian Clinical Drug Data Set (CCDD).  Every time a new IG pack is generated, this subset will get updated with the most recent values.  There is no fixed cadence for IG pack generation but normally new IG packs are generated for each new release of PrescribeIT.

Data Elements: All of the subsets used in ePrescribing have a set of associated data elements that can be downloaded here.

ICD-10-CA

The Indication for Use subset uses the ICD-10-CA code system which must be appropriately licensed from CIHI before implementation and use. More information about Licening can be found on InfoCentral.

HL7 Subsets

The description field in the HL7 subsets is optional. It was left empty where it did not add to the understanding of the concept definition. 

Pre-Adopting Codes

Pre-adoption is defined as implementing a new code before it is official released in the next version of the reference terminology.
