#1 - Requesting clarification about which code system version listed in the HTI-2 is the overwriting one for the minimum version, when there are differences between the version listed in $170.207 vs versions called out in USCDI V4 referenced in $170.213 or a version specified in an implementation guide for any particular subsection. Example here is LOINC 2.76 in $170.207vs LOINC 2.74 in USCDI V4 in 170.213. HIT systems should be using the most recent version available at time of certification.
#2 - Need clarification why LRI is listed as a standard under 170.315.(a)2. As currently written, this section does not provide enough clarify about which actor function for a use case requires which standard - this should be split out into specific use cases and describe the standrds standards for each actor:
Use case provider ordering from laboratory
actor EHR-s uses CPOE and then LOI to create and send orders
if applicable: HIE must receive LOI, perform any transformations / translations and send the modified order using LOI
actor LIS receives and validates LOI order
Use case laboratory ordering from reference laboratory (which could be a PHL or a bloodbank, too)
actor LIS uses CPOE and then LOI to create and send orders
if applicable: HIE must receive LOI, perform any transformations / translations and send the modified order using LOI - there should be a requirement that no content is lost (like specimen details or AOEs)
actor LIS receives and validates LOI order
If intent is to support use of LRI for results coming back after electronic ordering, then
Use laboratory sends results to ordering provider
actor LIS creates result(s) and uses LRI to send result(s)
if applicable: HIE must receive LRI, perform any transformations / translations and send the modified order using LRI
actor EHR-s receives and validates LRI result(s)
Use case laboratory receiving results from reference laboratory
actor LIS creates result(s) and uses LRI to send result(s)
if applicable: HIE must receive LRI, perform any transformations / translations and send the modified order using LRI
actor LIS receives and validates LRI result(s)
Question: Does this include sending a copy to ordering provider?
Question: Does this include an HIE?
could be included in all of these use cases - so should be added into the use cases
Intermediary Use (HIE): For HIEs to be certified HIT, there should be a requirement that no relevant content is lost (like specimen details or AOEs at the data element level or at the content level when mappings are not equivalent)
OTHER USE CASES
#3 Postpone Use of FHIR Cancer Pathology Reporting IG in HTI-2 as there is not currently FHIR capability in the US labortaory data exchange and request use of NAACCR V2.5.1 IG <ADD LINK HERE>, which is widely implemented for reporting to cancer registries.
#4 TEFCA - What does it mean for laboratories, where FHIR functionality is not available in regards to participation in QHINs and use of TEFCA?
Notes 8/27/2024
Can we use a software to figure out how the data is moving and how the content may have been changed?
<Ana or Ingeborg to provide the names of the implementations where this software has been used and maybe links to a publication that helps better understand the functionality>
this is more for data analysis in intergrated systems
it would require system errors to be reported to a central system
not sure we can call out a specific software in the HTI-2 rule - this is more importnat to include in implementaitons, not sure this can be part of the certification aspect.
From Chat:
We may wish to comment on to emphasize detailed specimen type, source, laterality, procedure for specimen collection are included with the order when collected so it's transmitted to the performing lab and available for PH for reportables whether via ELR or Cancer Reporting, etc.

I only brought up the HIE question because some HIE's provide mapping services between local code systems and from local code systems to LOINC and/or SNOMED. I wasn't sure if this is still a valid middleware layer that should be taken into consideration because the data isn't purely being passed through from source to target.Andrea Pitkus 1:00 PM
What do you consider a system error, how is it modeled, stored, collected and transmitted to achieve what you described?
