Organization

Presentation by Karima Planning & Technical committees Cochair elections Secretary To participate, your organization must first apply to IHE International. See apply form on www.ihe.net Then you can participate to any domain. To participate to LAB, email to Karima. To vote you must be in the roster. The cochair election is opened until 6 pm today (Kyoto time). Cast your vote by email to Karima. One vote per organization. IHE LAB needs a new secretary: A person whose organization is sponsoring the LAB domain. The request is opened from now to June 15. Contact Karima.

Inter Laboratory Workflow Supplement

Comments received: none This is a profile of interest at least for France. IHE France will have to advertise it to the IT lab community once again. Some comments addressed during the session. Among others: Explanation on the option "Report Fac-simile" and the option "Test addition approval". Decision to publish the supplement for TI, per the schedule. 

Action item: François

Italian microbiology issue

See the slides "microbiology_tree"
The current restriction in XD-LAB does not come from CDA but from an alignment with the V3 Lab Result message. This constraint does not exist in V2 results messages.
The solution based on a qualifier element, either directly of through the intermediate translation element is confirmed to be a misusage of the CDA schema. So the solution will be to release the existing constraint on the entry template of XD-LAB. Two possible variations:
a) Attach the isolate cluster directly below the observation that identified this isolate.
b) Attach the isolate cluster organizer below the culture battery organizer.
In parallel, the corresponding change request for the V3 lab message shall be submitted to HL7 O&O. 

Action item: François


XD-LAB and the ELGA project

Presentation by Alexander Mense and Stefan Sabutsch, see document "XDLab_Austria_IHE_f2f_20090514.ppt"
Needs for extending XD-LAB:

  • Provide the chief complaint section and the admitting diagnosis section from PCC, as an optional feature of XD-LAB.
Action item: Build CP for XD-LAB and post it to LAB mailing list --> Stefan
  • Ask PCC to explain how to validate against the cda.xsd a document (e.g. XD-LAB) containing extensions to the CDA schema (e.g. precondition for reference range), protected by a specific namespace. Example:
lab:urn:oid:1.3.6.1.4.1.19376.1.3.2
<observationRange classCode="OBS" moodCode="EVN.CRT"> 
<value xsi:type="IVL_PQ"> 
<low value="4.50" unit="10*6/mm3"/> 
<high value="6.00" unit="10*6/mm3"/> 
</value> 
</observationRange> 
<lab:precondition typeCode="PRCN"> 
<lab:criterion classCode="COND"> 
<lab:code code="SEX"/> 
<lab:value xsi:type="CD" code="M" codeSystem="2.16.840.1.113883.5.1"/> 
</lab:criterion> 
</lab:precondition>

Action Item: Request to PCC --> Charles
  • The LOINC specialty sections do not correspond exactly to the Austrian classification, to the French neither.


Change Proposals for XD-LAB

CPs #148, #149, #152, #153 finalized and approved 

Action item: Incorporate the CPs in the future LAB TF 3.0 --> François  --> Done.

CP #150 is accepted and assigned to Joost. the committee raises one concern about the proposed solution: This one batch message may be quite big, and the acknowledgement comes after the Code Set Consumer has integrated the content. Isn't there a danger of breaking existing implementations of the communication layer (MLLP)? Also because some HL7 message connectors are based on MSH segment, and won't work with a message starting with BHS.

  • Consider coupling the batch with the continuation protocol of HL7, to split the big chunck into smaller units.
  • Consider an alternate solution sticking to the existing sequence of 4 messages M08, M09, M11, M10, in which each message is systematically present even if it is empty because there is no object of that category in the code set.
Action item: CP To be finalized, with the rational --> Joost
