Working with DHQP for NHSN reporting	Nancy	Brief introduction to the Specimen CMT NHSN Digital Quality Measures using FHIR - single data stream once a month from hospital with ER or in-patient encounter for CMS requirements calculate glucose drop after insulin medication, sepsis mortality, HAI bacteremia, C diff treatement - see and subpages using LaboratoryObservation (QI Core) 6.0.0, DiagnosticReport (QI Core), Specimen (USCore) Narrative section in FHIR resources - not sure that is correct - that applies to CDA note that CLIA requires the test name, which US Core does not support until 8.0.0 NHSN requires standard codes to be used for this - LOINC valueset for each measure assume acute care hospitals will have to start reporting in 2028 - so that is the scope for the FHIR servers (assume EHR-s), but they will have to have coded lab results from reference labs in their system (which will need to be in V2 for now) LOINC list for blood culture - consider reviewing for any others available in LOINC Value set for specimen for each of the tests in the quality measure would it be helpful to identiy the preferred/acceptable SCT for the specimentype will continue the conversation next week
Call adjourned		12:03 PM EDT
Specimen CMT - Hosting Options	Riki	Any Updates on FU with: Clinical Architecture: ONC:
Specimen CMT terms	not today
CMT Governance process	not today
CMT proposed maintenance process	not today	Start writing this up on this confluence page: Questions from Zulip thread that should be covered by the process we come up with here: Requests for terms used in practice that are not yet in the Cross Map Table? Requests for any corrections or needed updates to terms? What type of version control will be leveraged for releases and major/minor updates? How do you plan to incorporate SNOMED CT Release Updates into Cross Map updates/releases? At what frequency will updates occur? For example, will you process SCT updates once yearly and have a subsequent Cross Map release yearly with changes or more or less often? How do you communicate differential changes between releases? Is a differential file produced or is it expected that users will be able to find changes on their own? What type of customer support for downloads is expected? Will the release entity provide or is it expected of the site hosting the content for download? Both need to work colLABoratively to ensure no blockers arise for users/consumers. User Guide starter
Follow up items	not today	Riki’s Follow up - none of these got done yet Contact United Network for Organ Sharing for input on donor terms (pre-coordinated or not?) = ISBT 128 \| ICCBBA \| Technical Documents https://www.isbt128.org/_files/ugd/1a7593_edfd176861c94dca94c34eff8fa3ad0d.pdf - for organs Riki has some contact now with European bloodbank and biobanks = Home - BBMRI-ERIC working with the folks that define their minimum data set: MIABIS - BBMRI-ERIC - these folks shared the follwoing for the reject reason topic, but it seems they differentiate between source site and the organ: #1 Standard PREanalytical Code Version 4.0 - (version 3.0 is here: https://cdn.ymaws.com/www.isber.org/resource/resmgr/isber_2019/pdf/standard_preanalytical_code_.pdf) and also Robin for US Clinical Archtecture unmapped LOINCs: Riki should check up with Charlie to see, if he knows where the LOINCs using the shorname in the description come from - as that is discouraged Riki to set up her VSAC authoring log in 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
Lab tests as procedures or orderables	Do we still need this?	Recommendation by SNOMED is that the Observable entity hierarchy be used for both ordering and resulting. As for the technique hierarchy, that in no way is intended to be used for either ordering or resulting laboratory tests. Those concepts are used to model both observables and procedures. SNOMED LOINC extension: The problem is that major EHR-s vendors have set up CPOE using Procedures for orders to initiate a workflow (that creates the triggering event in the system) - that’s where the push-back comes from. There is a CPT to SNOMED CT mapping (as a paid mapping available from AMA), but no LOINC mapping. Can we reach out to CAP Informatics, ADLM Informatics and ASCLS Informatics to get their take on where Lab tests should live We had said we would work through the Colonoscopy example: Reference links: clinical guidelines: Official journal of the American College of Gastroenterology \| ACG Quality Indicators: Official journal of the American College of Gastroenterology \| ACG For CAP cancer reporting is using SNOMED CT - would be good to look which they chose to represent the performed lab test There is this question in the LOINC Community: it is related to this US Core FHIR Change request: https://jira.hl7.org/browse/FHIR-54415 Answer to this one is that in USCDI Procedure (https://isp.healthit.gov/taxonomy/term/781/uscdi-v6) does not list LOINC as applicable Vocab standard in any verion, so remove it. Often folks think of lab tests as procedures, because they can be ordered in CPOE (and outsidde the US, in the UK for example that’s how folks have modeled those, which is why LOINC was adding more of the high level order codes in 2.81 release, so we still should tackle the LOINC community question. John was working on creatign an intesnional valueset definition based on class + type and maybe a few other attributes
European Semantic work	not today	Link to the German FHIR IG around suceptibility testing: Semantic Example section: Confluence page: Ask if Rob can keep us updated
Specimen CMT pilot implementers	not today	Review where we are: Vendor Connections
Specimen CMT - education	not today	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
Specimen CMT - tracking implementation impact Setting baseline Define metrics	not today
Future projects for this call after CMT	not today	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

Chat:

11:16:06 From Andrea Pitkus : Also these details could be exchanged in messaging across different parts of workflow (eg orders, results reporting, ph)
11:24:58 From Andrea Pitkus : I presented to ASCLS national mtg a few years ago.
11:54:58 From Andrea Pitkus : If folks are not familiar, this is what we've been discussing:
12:00:41 From Andrea Pitkus : Is there a user guide describing terms, usage, details. we've been discussing?
12:02:23 From Manjula Dharmawardhana (CDC) : Reacted to "describing terms, us..." with 👍
12:04:00 From Andrea Pitkus : sacher torte
