BRIDG Release 5.2.1
- BRIDG Release 5.2.1 is a very minor release that updates one class definition from the ballot reconciliation of the Anatomic Pathology Structured Report 2.1 (APSR) harmonization described below, adds one diagram leveraging existing semantics (a new CDMH View) and has corrected the HL7 release numbers corresponding to the BRIDG version numbers.
BRIDG Release 5.2
- BRIDG Release 5.2 is a minor release that adds semantics from the Anatomic Pathology Structured Report 2.1 (APSR) harmonization activity, HL7 Specimen DAM harmonization as well as changes from the BRIDG 5.1 ballot reconciliation. Each of these change topics are described in more detail in the Release Notes and Change Lists contained in the Release Package.
BRIDG and HL7 FHIR
The BRIDG Model is a Domain Information Model of the HL7 Biomedical Research and Regulation (BR&R) Work Group (WG). It provides the semantic foundation for relevant research artifacts created in the BR&R WG. Two BRIDG-based FHIR resources were balloted at HL7 in January 2018 and are now part of the HL7 FHIR R4 Ballot (Mixed Normative/Trial Use). The HL7 FHIR Resources of ResearchStudy and ResearchSubject have been informed by the BRIDG model semantics. BRIDG has also provided the State Transition Diagrams for ResearchStudy.Status and ResearchSubject.Status
The two BR&R FHIR Resources can be reviewed at the links below:
BRIDG Release 5.1
- BRIDG Release 5.1 is a minor release that adds semantics from the US Food and Drug Administration’s Common Data Model Harmonization (CDMH) project; the Anatomic Pathology Structured Report 2.0 (APSR); a new CDISC View Package; and removes several deprecated items. Each of these change topics are described in more detail in the Release Notes and Change Lists contained in the Release Package.
BRIDG Release 5.0.1
- On September 8, 2017, the BRIDG team announced the release of BRIDG Release 5.0.1, a minor release that addresses comments from the HL7 May 2017 Informative Ballot (BRIDG R3). The ballot elicited 31 comments, 12 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 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.
- 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.
