B.C. Health Concerns and Diagnosis Value Set

The British Columbia Health Concerns and Diagnosis Value Set was created to support a B.C. Ministry of Health initiative to provide consistent and standardized data in primary health care that facilitates sharing of health information across multiple systems in machine and human-readable format. 

This value set contains the most common clinical terms from SNOMED CT® (Systematized NOmenclature of MEDicine – Clinical Terms), ICD-10-CA (International Classification of Diseases - revision 10 - Canadian edition), ICD-9, and the CED-DxS (Canadian Emergency Department Short List) terms in British Columbia.

The SNOMED CT® vocabulary is used by physicians to capture encounter information at the point of care that can enable re-use of the data when mapped to a classification. The mapping of SNOMED CT® to ICD-9 supports physician billing, ease of use and acceptance of implementation into the electronic medical record (EMR) for primary care.

To confirm the validity of this value set, the Canadian Institute for Health Information (CIHI) Classifications and Terminologies team reviewed the mapped SNOMED CT® terms.

Scope

The audience for this mapping and guides are clinicians, EMR vendors and developers of information management/ information technology solutions for healthcare systems across B.C. and Canada.

The scope of this mapping is to provide a list of terms that are relevant to recording health concerns and diagnoses. This value set has 5,394 concepts with mappings to ICD-9, ICD-10-CA and CED-DxS.  Within an EMR solution, it may be used for such fields in a clinical record as patient’s current diagnosis, history, family history or reason for visit. 

The implementation guides will provide an understanding of SNOMED CT® and its advantages to EMR users as well as guidance for implementing this mapping to EMR systems. The use cases and best practices provide practical examples that an implementer can use to successfully integrate the value set in an EMR. Although the B.C. Health Concerns and Diagnosis Value Set is developed for use in British Columbia, it was derived from multiple sources - both nationally and internationally and is therefore anticipated to be adoptable or adaptable in other jurisdictions. 

Governance

This value set and its implementation guides have been endorsed by the provincial Health Information Standards Standing Committee (HISSC).

Current Status

Version 1.0 of this mapping is available for download. This version replaces the ‘Trial version’ of this value set, which was published in September 2019.

Maintenance

Significant analysis, review and validation processes were undertaken to make sure that the mapping developed would be applicable and attainable to the various stakeholder groups.

Wherever possible, content templates defined and reviewed by standards bodies were referenced, and appropriate constraints for the B.C. context applied.

The content of this mapping may require post-production edits, additions and/or maintenance to address issues identified by technical validation. Additional updates will be made over time to reflect current SNOMED CT® and ICD terms requirements in B.C. or to align with emerging pan-Canadian standards developments.
