Review of the proposed changes to LAW, led by Ed (sound) supported by Riki (image) … Very persuasive team.

3 of the 6 prepared word documents were reviewed. All 6 are available from:

Evolution in the management of field lengths

Pre-adopt v2.7 conformance rules
No more length for composite data type, rather define only the primitive data types in the subcomponents
Normative length rules – no truncation, but if an existing system cannot support the normative length for a field – need to send error messages identifying which fields a system cannot support the length constraints
Conformance length without truncation – for identifiers – also needs to create error message, if length cannot be supported – so we will need to agree on a lengths for these fields – minimize impact on existing systems
Conformance length with truncation – also agree on conformance lengths (CL)– can truncate above the conformance length – if a system can support longer than conformance length, can take un-truncated
Still need to generate error, if under the conformance lengths
Page 3 and 4 have the fields that should be considered for no-truncation CL
SAC and others using barcode may be reduced from 50= this would need to be reviewed
ACTION: For feedback on the documents – suggest to upload the documents with embedded comments – prefer to also list comments on the wiki

Additional Comment : Francois likes the direction, leveraging the later standard enhancements from later versions – also done in US realm IGs

Standardized image for graphs.

Needed for hematology domain – could provide standardization around the images for the graphs rather than the individual points to be re-constructed- Orchard has provided some input as well as Beckman Coulter
Questions? What is the basis to specify the resolution – why not include resolution and display size in the met data?
On manager size need to display the images, which may require dynamic display, and with non-rasterised image uses you lose readability of the chart – so standardizing on easy rules should help alleviate
Image size often associated with data content – should not be too difficult to deal with on receiver end, but some pre-determined display may be helpful
If a standard for transmitting figures is set up – structure of the message to carry multiple sizes to be accommodated in the messaging aspect while providing suggested preferred value
When the image is large enough – use RP for those
ACTION: Check with radiology message for metadata transmission – next step is to write up as true CP

OBR and TCD Fields

Out of these discussions pointed to other segments we support in the messages and that generated discussion about additional TCD fields that could be used
Added discussion points from Siemens and Roche
Additional TCD-9 to TCD-11 should be OO proposal first
Update TCD-2 to allow dilution factors
Added new document with HL7 proposal
Close gap on OBR field suggestions from Beckman Coulter

Housekeeping & Announcements

Call for proposals went out – deadline to submit is 3/31/2014:

Suggested proposals – will send reminder to google groups

May 12-14, 2014 Paris France Face to Face Meeting Agenda

Send suggestions to Francois via email <a href="mailto:francois.macary@sante.gouv.fr">francois.macary@sante.gouv.fr</a>

April 08, 2014 11:00AM ET/ 10:00AM Central

5 to 10 minutes for an update on LCC if Jim is available, so we know better what will be done on LCC during face to face meeting. (I remember there is a feedback awaited from Austin Kreisler, and a Change Request to be posted by Jim to OO)
40 to 45 minutes on LAW if Ed wants to.
