NOTE: you will need to use type “Event” if you do not have a confluence account
Lab tests as procedures or orderables
Definition from SNOMED for these hierarchies:
Observable entity: Information about a quality/property to be observed and how it will be observed
Evaluation procedure: No definition, other than it uses attributes that are similar to those used in the Observable entity hierarchy. Our policy is to not add any new evaluation procedures that would logically be in the Observable entity hierarchy.
Technique is a separate hierarchy used to model observable entities: A technique (also called method) is a particular way of performing an activity or task.
this could use some more guidance on when to use which of the referenced code systems - would like to understand when ICD would be used, and also would need guidance when to use CPT; SNOMED CT procedure codes vs LOINC should also be described
For CAP cancer reporting is using SNOMED CT - would be good to look which they chose to represent the performed lab test
Looking at the Colonoscopy example document (making changes in there)
Got to specimen requirements part of the document
Topic for next call
Nancy
CDC is working with the premier database to evaluate blood cultures - will invite team members to showcase their set up for review
Call Adjourned
12:01 PM EDT
European Semantic work
not discussed
Link to the German FHIR IG around suceptibility testing:
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
SNOMED CT Extension and use of RefSets (start with VSAC value sets as proof of concept and then migrate over) to indicate:
preferred specimen types by domain
maybe also terms that need additional attributes (by kind of attribute) if we also write an implementation guide for it
How do we decide what format to share this in - get input from EHR-s and LIS vendors:
Write letter of mulitple stakeholders to request EHR-s and LIS vendors to implement
indicating that this is a patient safety issue, as incorrect Abx treatment will contribute to multi-drug resistance (use CTSI findings to provide background)
focus on blood, urine, wound cultures (get data from NHSN, too)
Nancy is talking to DHQP about the linkage with specimen collection
While we have HIT certification that is for the EHR-s there is currently no enforcement for implementation at the organizations
need C-suite buy-in
Professional organizations - like CAP and ACOS and AJCC get them to write the synoptic reports (better structuring of data) - for surgical aspects - similar to what CAP has done for Cancer (though they do not have the SCT codes included in the past - may be including SNOMED CT starting in 2025, but they are also using the SCT codes for observables) https://www.facs.org/for-medical-professionals/news-publications/news-and-articles/bulletin/2021/12/synoptic-reporting-for-cancer-surgery-current-requirements-and-future-state/: The four CoC accreditation standards that include synoptic operative reporting requirements apply to sentinel lymph node biopsy for breast cancer (Standard 5.3), axillary lymph node dissection for breast cancer (Standard 5.4), wide local excision for primary cutaneous melanoma (Standard 5.5), and colonic resection for colon cancer (Standard 5.6). These accreditation standards were developed from the evidence-based recommendations for cancer surgery detailed in the Operative Standards for Cancer Surgery manuals.7,8
try to get AMA support to get providers to adopt this
Need education for providers and IT folks that helps with set up of the EHR-S / LIS configuration -this can be supported / accomplished? with the Implementaiton Guide we could write
if we have a use case of how a patient is impacted on their journey through the healthcare system - CAP created a nice video that showed how patient care was affected by incorrect data SHIELD FDA BAA Year 2
Specimen CMT - tracking implementation impact
Setting baseline
Define metrics
not discussed
Specimen CMT - Compare to NHS Medical Terminology testing
not discussed
Will get updated vocab at a later date
Future projects for this call after CMT
not discussed
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
Look at other HL7 tables that we would want to migrate SCT (i.e., Specimen Condition table, etc.)
