1.       Opening

1.1.    The conference was called to order at 2:00 p.m. US ET.

1.2.    The antitrust rules were reviewed, and DICOM patent policy as well.

1.3.    The agenda was approved.

1.4.    Approval of the minutes from June 26th and August 8th were approved.

2.       Argonaut Diagnostic Report for Imaging

The Argonaut Project (a consortium including HL7, EMR vendors, and others) is profiling “Clinical Notes” for interoperability within the US. Initially they were focusing on using the DocumentReference resource for unstructured notes, but now they are expanding scope to include use of DiagnosticReport for a number of uses, including Pathology, Laboratory, and Imaging. A concern was raised with Argonaut about profiling DiagnosticReport for imaging for US use in advance of II considering profiling DiagnosticReport for imaging in an international context. Brett Marquard, chair of the Argonaut Project clinical notes task force, presented the project to II.

 If anyone is interested in Argonaut project, please either contact Co-Chairs of WG-20 II at wg20chairs@dicomstandard.org or directly Brett Marquard at brett@waveoneassociates.com

https://argonautproject.github.io/clinicalnotes/

Please click on the following link if you are interested in Rad Reporting: http://www.radreport.org/

This topic will be on the agenda at the F2F mtg in October.

We might devote one or two quarter/s during II mtg.  The agenda has not been finalized yet.

We will discuss this at the next WG-20 II call: http://build.fhir.org/diagnosticreport.html;

3.       Tracker Item Review

3.1.    Identifier

There was a discussion on STU3 ImagingStudy identifier. Here is the example on how to represent accession number and study instance UID.

It is expected we will be removing the “use” requirements, since that was how we were differentiating the identifiers. Current thinking is to use “type” for this instead.

ImagingStudy.identifier should list Study UID and Accession number, but this is also the place to put any other study identifiers.

Unfortunately, to keep with FHIR methodology, DICOM UIDs will need to be prefixed with “urn:oid:”. And we need to fill in the code system.

For series and instance, it is expected that since we can stuff any identifier in there, we should change the cardinality to 1..* rather than 1..1.

Please note that an assigner has been added for the accession number. Since we don’t have an Organization resource, we have just used “MGH” for an identifier for site, which we expect to be consistent with how the local namespace entity id (0040,0031) of Issuer of Accession Number Sequence (008,0051) would be populated.

  "identifier": [

    {

      "use": "official",

      "type": {

        "coding": [

          {

            "system": "http://dicom.nema.org/resources/ontology/DCM",

            "code": "110180"

          }

        ]

      },

      "value": "urn:oid:1.2.840.74831.8.134.574.1.79.581004183",

      "system": "urn:ietf:rfc:3986"

    },

    {

      "use": "secondary",

      "type": {

        "coding": [

          {

            "system": "http://hl7.org/fhir/v2/0203",

            "code": "ACSN"

          }

        ]

      },

      "value": "W12342398",

      "assigner":

{

         "identifier":

{

              "value": "MGH"

              }

       }

    }

  ]

4.       FHIRCast

FHIRcast is modern, simple application context synchronization built on top of SMART on FHIR for the tight synchronization of full featured healthcare application, native apps or even synchronizing applications across multiple machines. See http://fhircast.org/ and the zulip stream for more info: https://chat.fhir.org/#narrow/stream/118-FHIRcast

September’s FHIR Connectathon FHIRcast track in Baltimore

The FHIRcast track at the HL7 FHIR Connectathon will further the specification and solicit additional feedback from developers, as we work towards a stable and mature specification for balloting into HL7. If you’re interested in developing and testing a FHIRcast implementation, there’s no better place than the connectathon! The track planning teleconference will be on Thursday, September 20th at 9am Central. Check out the track wiki page for details: http://wiki.hl7.org/index.php?title=201809_FHIRcast.

Sandbox Updates

Over the past month, the team has been working hard at improving the FHIRcast sandbox (https://github.com/fhircast/sandbox), which provides an easy on-ramp for prototyping and testing FHIRcast for interested developers. We’re still working on publishing the sandbox to something like https://sandbox.fhircast.org and on adding Websocket support to both it and the spec.

Specification Updates

We recently published the launch scenarios page - http://fhircast.org/launch-scenarios/ which describes how a SMART on FHIR standalone launch integrates a FHIRcast client into the driving system. This enhancement to the spec also resolves issue https://github.com/fhircast/docs/pull/25.

We’re already looking ahead to determine an appropriate timeline for an informative ballot FHIRcast into HL7 and are leaning towards either balloting at HL7 January, 2019 or May, 2019 meeting.

5.       FHIR Ballot 

http://wiki.hl7.org/index.php?title=FHIR_Ballot_Prep

Imaging Study – we plan to move it up to maturity level and have it as a normative candidate, right now is level 3.  No stability or QA issues to take care of as of now.

6.       Action Items for the next meetings
