1Introductions and Apologies

Matters arising from the previous meeting notes

2022-04-03 Anesthesia CRG at SNOMED Business Meeting (Pt 1)

3HL7 Anesthesia Record Domain Analysis Model Review

HL7 Domain Analysis Model: Intra-Procedure Anesthesia, Release 1 - Anesthesia - Confluence


Per Martin Hurrell, Project scope statement has completed review

Now we need to populate the value sets.  These will be defined in the implementation guide, not the DAM.  Both IG and DAM are informative.  Martin Hurrellwill come to this group to create term sets for use within the Implementation Guide.

4Terminology review

Reviewed spreadsheet of new ventilator terms - outstanding questions resolved, Monica will close out CRS requests

Reviewed existing SNOMED ventilator terms that are "procedures", moving to "regime therapy" because therapy occurs over a period of time

Next meeting Monica will return with loose ends if any

Reviewed Ellen Torrescontent analysis of regional blocks.  Conclusion is that most items are represented in SNOMED.

5Anesthesia CRG work plan

Would like to clarify where anesthesia CRG can be useful within SNOMED.  Ideas: clean up orphan terms?  staged review of anesthesia content?

Date of next meeting:

2022-05-24 Anesthesia CRG Meeting

  1. Thank you for the invitation to the meeting, it was great to meet (and catch up with) friends old and new.
    Regarding item 3, I spent some time looking at Ellen Torres epidural use case and cross-referencing some terms, using IOTATerms.owl as the first search, then the IHTSDO browser.

    It's a work in progress, as you might imagine, but there are a couple of things that came up in the initial searches.

    1. How does SNOMED handle the concept of baricity in relation to meds such as hyperbaric bupivacaine.
    2. Not directly relevant to epidurals, but how might an assessment such as the 'stop before you block' be handled in SNOMED. This is a risk assessment that falls into the category of safety checklists but there might be scope for some terms related to it. 
    1. Grant, regarding 1, I suggest adding bupivacaine 0.75% with Glucose 7.5% as a product

      regarding 2, I would use the existing "surgical time out procedure code"

      regarding 3, I'll have a look later 4 surgic15682000 | Surgical time out (procedure) |

      1. Thanks Steven, re. 1, that would certainly work, but my understanding is that  Hyperbaric bupivacaine can also be produced by the addition of glucose (80−1) to isobaric (‘plain’) bupivacaine 0.5%, which would be 8%. No doubt other preparations exist. Give the variety of units used and preparations, I think what I was saying is that there may be a need to express the concept of 'baricity' without reference to pharmaceutical preparations, but I'm not sure how that could be done.
        Should we move this to 'discussions' ?
