BRIDG & ISO
BRIDG 3.0.1 was first balloted in ISO in 2010 through the Joint Initiative Council (JIC) whereby ISO, CDISC and HL7 balloted BRIDG concurrently. Around that time, BRIDG was given the identifier ISO 14199. Comments provided in that process were addressed during the ISO meeting in Brazil in May of 2010 and resolutions published in the next release of BRIDG 3.0.3 in Dec. 2010. BRIDG was balloted in ISO again, this time release BRIDG 3.2, in 2015 and it passed the ISO balloting process. BRIDG is now an ISO standard, ISO 14199. ISO has been added as the fifth stakeholder in BRIDG and is now represented on the BRIDG Steering Committee.

ISO standards are expected to be reviewed every five years, so the 5.3.1 version of BRIDG will be balloted again in ISO in 2022.

BRIDG & DICOM
In order to support the use of imaging in research and clinical trials, various components of the Digital Imaging and Communications in Medicine (DICOM) (ISO 12052) information model, have been incorporated into BRIDG. In particular, the information necessary to identify and describe the protocols defined and used for the acquisition of images has been mapped, and corresponding classes and attributes added to BRIDG. The concepts used in DICOM for structured reporting of results, particularly for quantitative imaging, have been incorporated and mapped into the observations class structure in BRIDG. Sufficient imaging-related concepts were added to BRIDG to support interfacing between a Clinical Trials Management System (CTMS) and a DICOM-based Picture Archiving and Communications System (PACS), so that researchers can formulate queries to search for imaging studies of interest in the CTMS, without trying to replicate the entire DICOM standard within BRIDG.
