TODO
- Determine computed scope of ICD-O by looking through current map and determining transitive closure.
Agenda/Notes
- Scope of ICD-O
- * * One level up in the hierarchy (malignancy by morphology, etc..) - 1700+ cases
- * * many not mapped (if a concept has subconcept, the child may not be fully mapped to ICDO codes)
- * * double-check that existing map is correct (e.g. concept request for Orphanet - small cell carcinoma - specific subtype).
- * * when look at morphology in SNOMED - this is a synonym. In ICD-O, treated same as a synonym - shouldn't be. should be sub-type.
- * * Also issue with NOS - will have a specific name.
- * * Limit scope for now - look at refset mapping - only retrieve transitive closure of descendants of those concepts.
- * * Scope in SCT hierarchy - can identify a single concept to subsume everything (in scope)
- * * * ISSUE: quite a few things in SCT that are out of scope in ICDO
- * Existing state of mapping (and style of mapping)
- * * Are what is in map correct?
- * * Are there things missing?
- * * SCT has continued to change, but not the map. There have been only inactivations due to retired SNOMED concepts.
- * ICD-O - version 3.1 (2011) - not changed in 5 or 6 years
- * * Need to get file from WHO - still asking around to get the file
- * * Some weird data, including / and digits after /
- * * include 6th char? -
- * * No index needed
- * * Preferred names and synonyms.
- * QA - number of issues in existing map that need to be developed. Be able to see mapping side-by-side, and with SNOMED hierarchy (for QA)
- Consider migration to ICDO 3.2
- need to promote certain (SNOMEDCT) content for mapping
Questions
- Scope of SNOMED CT? A: for now, concepts in the map and transitive closure
- What is codable in ICD-O (e.g. rules)? A: TBD, but look at existing map
Resources Needed
- ICD-O 3.1 (2011) data file
- SNOMED to ICD-O map (including refset id, etc.)
- In SimpleMap refset file.
- Map project metadata
- Type of refset - Simple
- Workflow path?
- Need an option to map to nothing -> have a target code for this?
- Yong-> map lead or specialist?
