Standards Inventory

Pan-Canadian Standards provide the technical language and clinical terminology to enable the thousands of health care providers across the country to communicate and share health information in a consistent, safe and reliable manner. When used in eHealth solutions, these standards:

  • support members of the care team to accurately interpret and exchange information needed for safe and effective care
  • facilitate clinical decision support for alerts and reminders
  • enable data to be aggregated, with appropriate approvals, for clinical research, ultimately leading to better outcomes

Pan-Canadian Standards Inventory

This inventory includes all standards that have been designated as pan-Canadian Standard. These standards have gone through an open, transparent evaluation governed by jurisdictional representatives, clinicians, vendors and leading experts in standards and architecture. Pan-Canadian Standards can be internationally based, led by Infoway, or developed by external stakeholders for a specific Canadian initiative. A pan-Canadian Standard is any document or artifact established by pan-Canadian consensus.

Pan-Canadian Master Terminology Worksheet and Messaging Artifacts

To support the pan-Canadian messaging standards, the following business and technical artifacts have been created:

  • Master Terminology Worksheet (MTW): A human readable Excel file that provides links between the messaging artifacts and the terminology worksheet. It also includes the business rules to generate the allowable value set contents and URLs to the related code systems. It covers all messaging standard domains.
  • Terminology Implementation Guide: Provides implementation, compliance and conformance guidelines for use in developing software that conforms to Infoway’s Message Specifications. The Implementation Guide has been available since Maintenance Release 2009.
  • Vocabulary Model Interchange Format (MIF): Files that provide a way for computer systems to consume the information in the MTW. The MIF has been available since Maintenance Release 2009.

* Status Definitions

Canadian Draft for Use (CDFU) - The standard has been developed but it may or may not be implemented or be in use. The standard is considered ready to be used by early adopters: however, change is probable as stakeholders begin using the standard in implementations.

Canadian Approved Standards (CAS) - The standard is in use for the purpose(s) or context(s) for which it was intended. Only those parts of the standard that have been implemented or are in use can progress for consideration as CAS. This decision point signifies that the standard has reached a level of stability and is comprehensive enough such that major changes are not expected.
