Discussed?

Notes

Upcoming OOO

Yes

  • Riki HL7 WGM 1/29-2/2

  • John OOO: HL7 WGM 1/29-2/2 (maybe?)

  • Raj OOO: 1/18, 1/25

  • Kathy OOO: 2/29

Previous Action Items

Yes

  • Nancy Follow up

    • Can only have 1 bodysite in HL7, but these are from different sites - find out how often cervix + Fornix are collected together

      • ComboCytologicalMaterialfromEndocervixEctocervixVaginalFornix

      • ComboCytologicalMaterialfromEndocervixEctocervixVaginalFornixSlide

      • Labcorp allows multi-select - they use AOE question for this

      • We can’t have multiple sites in HL7

      • how to map for body site? - if there are multiple body sites - we decided that we will leave that body site field empty and require a comment in NTE segment to specify body site

    • We still need reference to thin prep (request new term with parent cytology specimen container (physical object) for “liquid-based cytology specimen container”) - we don’t want to use the trademarked name “ThinPrep”, but it can be done in US extension

      • We need to know what is in the thin prep liquid - this may be proprietary

      • John could add “liquid-based cytology specimen container” to the US extension

        • …with liquid-based additive?

        • specimen cytology container with ThinPrep (or SurePath) liquid - will be in line with “cytology specimen container with ThinPrep liquid”

        • “cytology specimen container with SurePath liquid”

          • *composition of the liquid will change based on the purpose of cytology and use

        • Don’t want to combine the trademarked name in one SCT term

        • John will look into this

        • Decision: Keep the term generic -“liquid-based cytology specimen vial” and may include ThinPrep and SurePath as synonyms

          • ThinPrep vial and SurePath vial? (Vials are shorter and wider than the test tube) - “vial” is more preferred

          • “Vial” and “container” are not semantically equivalent – “vial” might be the preferred to use in the term

          • John can work on this and send a CRS request

    • nasal sinus fluid definition

    • surgical insertion site peritonealDialysisTunnelSite

    • surgical insertion site peritonealDialysisSite

  • Riki’s Follow up:

    • submit a code for formalin10

    • work with John

      • new term for pacemaker insertion site sample

        • in SCT there are only swabs for insertion sites (line, drain, chest tube, vascular catheter) - this should be fixed

        • we should model it after 435971000124108 | Body fluid specimen from peritoneal dialysis insertion site (specimen) and require method, which should be aspirate

      • For wound modeling (see 2023-11-30 LabMCoP Meeting Notes ) create a few pre-coordinated specimen terms

        • to cover the wound causes as children under: 119365002 | Specimen from wound (specimen)

        • another child term for aspirate under 445611000124106 | Specimen from bite wound (specimen), since that is preferred over the existing swab

      • IDSA has a guidelines for wound cultures (deep and superficial - related to surgical wounds) - link sent to Amy

      • 460621000124104 |Superficial surgical incision wound (morphologic abnormality)| - created in US extension in 2019. Is this needed? If so, then LabMCoP/APHL should promote it to SNOMED International to retain US SNOMED identifier. John will submit this to be promoted.

  • Open homework EDTA Stopper top

Modeling donor organs / parts

No

  • Outreach out to Jane Pollack (jpollack@nmdp.org) at NMDP. was successful - schedule call for this topic - waiting for answer on what date will work

    • Nancy/Amy to reach out to Jane Pollack

    • Another contact: Scott A. Brubaker Division of Human Tissues, Office of Cellular Therapy and Human Tissue CMC, Office of Therapeutic Products, Center for Biologics Evaluation and Research, Food and Drug Administration, Silver Spring, Maryland, USA

      • Incomplete tissue product tracing during an investigation of a tissue-derived tuberculosis outbreak - ScienceDirect

  • Should we make pre-coordinated terms, or support use of type modifiers?

Specimen CMT - review of terms with questions

 No

  • CatheterTip_IndwellingUrinary- discouraged, not appropriate for collection. Added new PHLIPPrefName

    • Urinary catheters: MedlinePlus Medical Encyclopedia

    • Change SPM 5 (foley catheter (physical object) SNOMED code with 23973005|Indwelling urinary catheter, device (physical object)|

    • Term “foley” is identified in different areas (description, definition, etc.) so they code may not need to have term “foley” in it.

    • Ask Riki for her opinion (tie-breaker)

  • Catheter Tip, Hemaquit

Specimen CMT pilot implementers

 

Specimen CMT - Hosting Options

 

  • How can we publish the content in the dB?

    • Allow access somehow to query the dB

    • as access or excel or csv

    • Using FHIR conceptMap similar to Conceptmap-example-specimen-type - FHIR v6.0.0-cibuild - based on this profile: ConceptMap - FHIR v6.0.0-cibuild

    • ​ to ask Eric if he still has that or how he built it:

    • ANSWER FROM ERIC:

      • if you look in the xml source Conceptmap-example-specimen-type.xml - FHIR v6.0.0-cibuild . you can see how it is mapped. 

      • I am not sure if you mean the table rendering or creating the concept map from a spreadsheet or CSV file.  The FHIR build tool did the table rendering for that mapping, I think I entered the data by hand, or Grahame did it. It would not be hard to create a script to create a concept map from an excel or csv file if needed.  The table needs to be large enough to make it worthwhile though. you could even create formula cells in the spreadsheet to generate the XML or json for each item. and then copy to a text editor and append to the Metadata fields.

Specimen CMT - education

 

 

Specimen CMT - tracking implementation impact

  • Setting baseline

  • Define metrics

 

 

Specimen CMT - Compare to NHS Medical Terminology testing

 

 

USCDI v5 draft

 

https://www.healthit.gov/isa/united-states-core-data-interoperability-uscdi#draft-uscdi-v5 has been published - comments due by April 5, 2024

LOINC to SNOMED CT mapping

 

 

Reporting Biomarkers to Cancer registries

 

National Program of Cancer Registries (NPCR) | CDC

Sandy will put together a one-pager

Future projects for this call after CMT

 

  • In general the call is intended as a forum for ANY messaging related issues to work out.

  • In the past we have

    • reviewed containers re-vive that - and how does that interact with devices (UDI identification?)

    • review code systems around additives (HL70371 and SCT substance and product hierarchies)

    • started work on cross-mapping between HL7 method codes and SNOMED CT procedure / technique concepts

      • American College of Surgeons is working on procedure protocol and synoptic data elements / surgical synoptic reports - we could work with them together on that
