About

What is the Health Terminologies Community?

The Health Terminologies Community is a place to share and learn about new and existing implementations of, and updates to, health-related terminologies, terminology subsets, and classification systems used in Canada.

Members actively contribute to discussions and share information and advice related to the implementation, development, maintenance, and use of multiple vocabularies in various health-related projects.

This community is responsive to its membership, actively encouraging, welcoming, and relying on the submission of discussion topics, agenda items, and other items such as education and vendor engagement from its members.

The community will engage and collaborate with other groups or InfoCentral communities on broader related topics when relevant.

Major reference terminologies and classification systems of interest include, but are not limited to:

  • SNOMED CT
  • LOINC/pCLOCD
  • CCDD (Canadian Clinical Drug Dataset)
  • ICD-10-CA
  • ATC

Canada Health Infoway is the National Release Centre (NRC) for SNOMED CT, pCLOCD, and HL7 in Canada.

The Canadian Institute for Health Information (CIHI) is responsible for the development and publication of ICD-10-CA (the Canadian modification of ICD-10), as well as CCI (Canadian Classification of Health Interventions).

To become a member of this community select Join Group in the Group Menu.

If you have an idea for a community, working group, or project that will drive interoperability forward, let us know! Send your suggestions to standards@infoway-inforoute.ca.

Hello all. This is a cross posting. The Health Analytics Community is hosting the Public Health Agency of Canada on Thursday, Sept 23, 2:00-4:00 PM (Eastern) and will focus on the development of a pan-Canadian Health Data Strategy. The initiative aims to support the effective creation, exchange, and use of critical health data for the benefit of Canadians and the health and public health systems they rely on. The purpose of this virtual meeting is to hear views on how we should work together to formulate a strategy to overcome the barriers that have prevented progress in the past, to identify and prioritize strategies to address root causes and to develop and plan for an environment in which new ideas will flourish. We believe that the unique insights, experiences, and knowledge you hold with regard to this topic would be invaluable in helping to inform the development of this strategy. We value your participation. The link to the event: https://www.eventbrite.ca/e/170857548527

Thank you all for contributing to this discussion. We appreciate your collaboration and partnership on this issue. Summary: An issue was reported by Anibal from QC related to space-encoding in the March 2021 CA Edition release package RF2 files. Upon investigation, it appears to be that extended ASCII encoded non-breaking spaces (NBSP) are present in the files instead of the expected regular space . It was found that the NBSPs were introduced into the files via copy / paste functions from HTML based tools. Our technical team found “…32 in the delta, 75 in the snapshot, and 112 in the full. That means that 32 are new in this release, there are 43 existing ones from previous releases, and 37 that were once published as NBSPs and replaced later.” This issue will be corrected in releases going forward, and all spaces will be encoded with regular space ASCII . Anibal has confirmed that preprocessing has addressed the issue. Given the imminent release of the September 2021 CA Edition, and the fact that re-issuing the March release will create a much larger impact than simply correcting the issue in subsequent releases, new March 2021 CA release files will not be generated. The NBSPs will remain. Implementers are advised to use the September 2021 CA Edition Release.

Linda Parisien created a new discussion in Health Terminologies

This is one of a series of briefing notes related to Content Improvements in the Substance and Product Hierarchies. The purpose of this briefing note is to seek feedback from the SNOMED CT Members for poisoning concepts that are defined by a causative agent that is of type “medicinal product role” e.g. 290578000 |Antineoplastic poisoning (disorder)| or “Medicinal product role + structure” e.g. 290950009 |Barbiturate antiepileptic poisoning (disorder)|. For each concept, kindly advise: - What is the frequency of use? - If in use, provide supporting use-case(s) specifically, please clarify why the poisoning concept is used in place of an adverse reaction or overdose defined by the same causative agent. Please provide feedback to the project group via info@snomed.org by September 20, 2021. Thank you!

Linda Parisien created a new discussion in Health Terminologies

Purpose To obtain feedback from (MF/CMAG) on the suggested inactivation of concepts which refer to the intent of an endoscopy procedure as diagnostic or therapeutic. Background Following a customer request for a new concept, Diagnostic colonoscopy (procedure), an internal review examined the use case for this and similar existing concepts. Including the intent of a procedure in the description is currently a precoordination pattern that is generally not allowed in the international edition but legacy content exists in this format. Identifying the intent of a procedure can be problematic as a procedure may be ordered as diagnostic but during theprocedure a therapeutic process is undertaken e.g., polyp removal during a routine colonoscopy. Additionally the context of the procedure will be clear from other information in the clinical record. Issues Creating a new concept Diagnostic colonoscopy (procedure) as a subtype of 73761001|Colonoscopy (procedure)| could result in implementation issues where the existing concept has already been used for diagnostic purposes. This issue would apply to any requests for diagnostic or therapeutic endoscopy procedure concepts where the agnostic concept exists. It is not thought that this would impact procedure planning activities as endoscopy units are prepared for the procedure to change course if required. Inactivation of endoscopy procedures stating intent as diagnostic or therapeutic: 77 concepts affected, 363071007 |Diagnostic endoscopy (procedure)| and its subtypes together with 7 therapeutic concepts. Next Steps We propose this format continues to be disallowed in favour of content that is agnostic to intentand inactivation of existing concepts would be the preferred approach. The inactivation reason would be non-conformance to editorial policy and our intention is to add a historical association of “REPLACED_BY” to an appropriate target replacement concept once the updated concept inactivation reasons have been implemented in the authoring tooling. SNOMED International would appreciate any feedbackon the proposed inactivation of this content before September 13. Thank you!

Do you have a simple one-liner that works in Mac OS X Big Sur without having to install anything more complex? My family MacOS expert tells me that you could just use "sed s// /" where is the literal, copy-pasted character. Let the tool deal wit...

Found issue with space encoding in Description file in RF2 for SNOMED CT release 20210331 09/03/21

I found out the reason, it's UTF-8 encoding: http://www.ltg.ed.ac.uk/~richard/utf-8.cgi?input=c2+a0&mode=bytes So, the actual NBSP (No-break space) in UTF-8 is xc2xa0 so that's why my gsed from before fixes the issue. CHI, please fix this fo...

>> Look for a0 and you'll see the issue. Look at the two previous bytes, 6d and c2. 6d is the 'm' in Achaetomium, c2 is the Â, which you see once you do the gsed command to get rid of the 0a. Aníbal, that would be the UTF8 representation of NBSP (...
