BRIDG Release 5.0

  • The BRIDG team announces the release of BRIDG 5.0 on Feb. 1, 2017. This release includes a new sub-domain for Imaging semantics from relevant portions of DICOM and NCI’s Annotation and Image Markup (AIM) project. It also contains new semantics from a vendor who is using a BRIDG-based model in a clinical trials management application. And it contains a few new semantics from the harmonization of concepts from NCI’s Surveillance, Epidemiology and End Results (SEER) program. BRIDG 5.0 will be balloted by HL7, CDISC and ISO in a joint ballot cycle process culminating with ballot reconciliation beginning at HL7’s May 2017 Working Group Meeting.

BRIDG Release 4.1.1

  • On Aug. 8, 2016, the BRIDG team announced the release of BRIDG Release 4.1.1, a minor release that addresses comments from the HL7 May 2016 Informative Ballot (BRIDG R2). The ballot brought forth 16 comments, 10 of which were deemed to be persuasive or persuasive with modifications, according to the HL7 ballot process. These comments resulted in a small number of minor changes to the User’s Guide and the UML Model.

BRIDG Release 4.1

  • The BRIDG team announces the release of BRIDG 4.1 on March 18, 2016. This release includes resolutions to HL7 ballot comments from the BRIDG 4.0 May 2015 HL7 Draft Standard for Trial Use (DSTU) ballot cycle. It also contains new semantics from a vendor who is using a BRIDG-based model in a clinical trials application. BRIDG 4.1 will be balloted in HL7’s May 2016 ballot cycle as an Informative ballot. 

Future Plans

  • Based on comments during the BRIDG 4.0 balloting cycle, the HL7 BRIDG WG is looking to build subject-matter-expert-friendly views of the BRIDG model to make it more easily consumable by domain experts.
  • The BRIDG team is actively working on interoperability scenarios involving DICOM Imaging in the context of clinical trials. This project will be the first to reconcile BRIDG semantics with other standards using an approach called ‘modeling by reference’. This approach is part of a broader effort to review the BRIDG architecture and ensure the scalability and viability of the model going forward. Also, additional semantics from other stakeholders will likely be harmonized into the next release of BRIDG.

BRIDG is ISO 14199

  • Several years ago the BRIDG Board of Directors decided to advance BRIDG to the status of an international standard through the International Organization for Standardization (ISO) process under ISO Technical Committee 215 for Healthcare Informatics, which included joint SDO balloting through the Joint Initiative Council (JIC). This collaboration provided the opportunity to gather feedback from a variety of key member countries and stakeholders, applying recommendations to improve the BRIDG Model. In May 2010, BRIDG R3.0.1 passed the first round of joint balloting in ISO TC215, HL7 and CDISC. All comments were addressed and published as part of BRIDG 3.2 September 2012. Most recently in 2015 BRIDG R3.2 unanimously passed the ISO DIS ballot as a Draft International Standard which allows BRIDG to advance directly to publication. BRIDG is now an ISO standard, ISO 14199.
