CG Working Group Meeting Minutes

Meeting Minutes - HL7 WGM

• CG Monday Q3 Joint with CIC
  • Attendance: CG - Joyce and Amnon, CIC - Anita and Ed
  • M&M is in the process of coming up with some DAM guidance for HL7. It is our understanding they will be starting with the document CIC created on the subject.
  • Lloyd McKenzie is spear-heading this effort. The DAM guidance will be based on the document produced by CIC on Feb. 2011.
  • Spoke about the different projects with a focus on how the disease projects in HL7 are interfacing with the CDISC therapeutic area standards. The modeling effort in HL7 is focused on clinical and administration domains
  • Example interaction for cardiovascular standards:
  • CDISC ACS (Acute Coronary Syndrome), HL7, FDA working through C-PATH (funded by Gates Foundation) work on identifying disease data end points and DAMs.
  • Subsequently these end-points are presented to the CDISC SDS team for inclusion into the standard.
  • HL7 WGM Vancouver May 2012

• Tues Q3
  • Attendance: Amnon Shabo, Bob Milius, Jill Kaufman, Joyce Hernandez, Phil Pochon, Grant Wood
  • Jill suggests that the CG WG consider doing a CME tutorial at the next WGM in Baltimore.
  • Amnon reviews the agenda.
  • Joyce suggests we get AP more involved in Omics DAM development.
  • Amnon gives a quick description of the new HL7 initiative called FHIR.
  • A deeper discussion is scheduled for Wed Q2.
  • Amnon also gives a quick description of an outside effort called iPOP. A deeper discussion is scheduled for Thurs Q2.
  • He then went through a review of CG activities.
  • Joyce had a question about O&O Lab 3.0 and genetic variation. Phil shared related efforts with CDISC and RCRIM.
  • Lab V3 no research or genomics – also need to upgrade specimen semantics
  • Research labs could use V2.5.1 message
  • Sponsors might be more interested in a V3 XML solution – add clinical research concepts – study, visits, subject id etc. into O&O Lab V3 message. Unclear what is going to be used on the Research side.
  • Can we use FHIR?

• Tues Q4
  • Attendance: Amnon Shabo, Bob Milius, Joyce Hernandez, Phil Pochon, Lisa Schick, Grant Wood
  • Amnon continued his slides on CG activities, reviewing CG CMETs and the Pedigree specification.
  • Genetic Variation - Take out specimen handling and identifiers that will be revised in the current Specimen project
  • The Phenotype CEMT model is okay since we are pointing to a separate model
  • Associated Observations are used through controlled vocabulary
  • The Pedigree model was successfully reaffirmed in HL7 balloting, with Release 2 and a US-specific Implementation Guide under development; Exchange of pedigrees in CCD was discussed; Pilots: Hughes Risk Apps and Surgeon General.
  • The V2 Implementation Guides publishing status was given by Grant. Official HL7 publishing forms have been completed, and the TSC will (likely) approve the guides at their next meeting.
  • Amnon reviewed the CG DAMs (Clinical genomics including gene expression, and clinical sequencing). Amnon concluded with a review of CG work on clinical sequencing workflows and use cases - from summary slides written by Mollie.
  • Bob presented his work on HLA tissue typing. This comes from the NMDP matching program, and interest in adopting HL7 standards (CDA GTR) to transmit and receive electronic data with transplant sites. He gave an explanation of the NMDP HLA tissue typing nomenclature version 3. Their Allele types cover up to 6 exons and 800 SNPs. Bob reviewed the NMDP gold and silver standards for reporting data. He showed how he is attempting to put this data into a CDA GTR and Genetic Variation message. They have 150,000 allele codes, but are looking for a different code format. They are looking to use GL Strings for the report, and QR codes that can take you back to the original sequence.

• Wed Q1
  • Attendance: Amnon Shabo, Joyce Hernandez, Phil Pochon, Lisa Schick, Grant Wood
  • This was a joint meeting with O&O, II (Imaging Integration) and AP (Anatomic Pathology). AP is discussing using the same unique identifier throughout the sample collection, sample prep, lab accession, and result reporting process. They are discussing using a dumb (random number) or smart identifier (meta data, code that describes the specimen). Either way, the container is what is labeled.
  • APSR – Anatomic Pathology Structure Report is a joint IHE-HL7 AP initiative and includes 21 CDA templates (Document Content Modules) and 490 observations and procedure templates
  • The discussion then switched to some of the molecular biology work based on CAP protocols and AJCC (American Joint Committee on Cancer)
  • They are working on a design to implement "value sets" a constrained set of terminology.
  • Based on high-level requirements it seemed they wanted to have a unique identifier that corresponds to the status of the samples as it is processed: bio-specimen collection, resection, and glass slide.
  • Various techniques of associating an id to a specimen were discussed – affixing a barcode on a specimen to bar-coding the container.
  • Two current ideas regarding the specimen ids were mentioned:
    • Use of a pseudo random number
    • Building intelligence in the key. The ramification is that the key would need to appropriately be sized to handle the required built-in intelligence.
    • Specimen process is current documented in DICOM 5.17 specs which are currently informative.
    • DICOM is using OIDS to provide unique identifiers for specimens and containers.

Wed Q2 - Amnon Shabo, Joyce Hernandez, Lisa Schick, Grant Wood

Amnon reviewed the status of CDA GTR. Joyce suggested separating human and viral genomics in the Genetic Variation section. Amnon describes the concept of clinical genetic statements. He suggests we consider doing dynamic binding of answer lists. Amnon then reviewed what he calls the Layout Challenge (see slides in the overview presentation at our page in the HL7 main site), the question of the separation of CDA rendering and logic. A motion was made to adopt GTR sections, get LOINC codes for those sections, then offer style sheets (CAP, ACMG, JMD). the motion received no objections. Amnon plans to do tissue typing pilot with Bob and two transplant centers. Grant plans to do a pilot with Pathology group at Intermountain, and hopefully Myriad and ARUP. Don Rule has also talked about doing a CDA GTR pilot on previous CG calls.

Family history in Meaningful Use Stage 2 was discussed. Amnon continued slides that reviewed the Pedigree Release 2 Implementation Guide work, the question of Pedigree and the new HL7 FHIR. Joyce commented that the IG should show how to move from CCD to full Pedigree. Amnon slides will be posted to the website.

Wed Q3 - Amnon Shabo, Joyce Hernandez, Phil Pochon, Lisa Schick, Grant Wood, Elaine Ayers (NIH)

Omics DAM ballot reconciliation and comments were addressed. There was not enough time to complete this process.

Wed Q4
