Registry Data

The IR registry collects data for procedures involving the placement and removal, where applicable, of lines and filters. Reporting templates, developed by the Society of Interventional Radiology (SIR), standardize and structure IR procedure data to create quality measures that can be compared to national benchmarks. Templates are currently available for

  • CVA tunneled catheter placement and removal

  • CVA non-tunneled catheter placement

  • PICC placement

  • Venous port placement and removal

  • Venous filter insertion and removal


The registry uses procedure data to create six specialized IR measures, five of which may be reported as QCDR measures for MIPS, and 15 CMS-defined MIPS measures. See IR Measures for a complete list of available quality measures.


The IR registry collects summary and detailed data about each measured procedure, including impression and plan data. The registry does not collect Protected Health Information (PHI) such as patient name, date of birth, etc. Instead, a unique patient identifier is created and transmitted, to allow for longitudinal tracking of a single patient without using PHI. Refer to the IR Data Dictionary for a detailed list of data elements collected, and IR Data Collection Using TRIAD for more on how data are anonymized before transmission to the registry.



Data Submission Components and Data Flow

Data collection is an automated process that utilizes three components

  • SIR standardized templates, to structure the data

  • HL7 messaging, to transmit data across medical systems

  • TRIADTM Site Server, to capture, format, and submit data to the registry

IR Data Flow

The SIR’s standardized reporting templates structure registry data during the dictation process so that the correct data elements and values are captured. For example, the templates tag each procedure with the correct, pre-determined label so that the TRIAD software can identify the message and transmit relevant data elements to the registry.

SIR .XML template files are optimized for use with PowerScribe 360® and can be customized, and .RTF versions (rich text files) may be modified and imported into other systems, as needed. Consult your software vendor or local IT team for help loading templates during the setup process.

HL7, or Health Level Seven, is a communications standard for exchanging health-related information between medical applications. Each message contains data about a particular event, such as a patient admission, procedure or observation. Information is sent as a collection of one or more delimited text messages, each containing one record of health-related data (see example, below).IR Sample HL7 Message

The ACR’s TRIADTM software, installed locally on a computer at each participating facility, “listens” for HL7 messages as they are transmitted from dictation software to other medical systems within the facility. TRIAD identifies specific procedures to be sent to the IR registry, parses each relevant message, anonymizes the data, and transmits only the required data elements to the IR registry through the NRDR portal.IR Data Submission Using Site Server

Note: TRIADTM Site Server is a “passive listener” that monitors the HL7 messages transmitted across your internal network and does not require direct access to local computer systems, such as Epic.

TRIAD has transmitted data from more than 2,000 sites to the ACR’s Dose Index Registry (DIR) since 2011. Site Server is registry-specific, so facilities currently participating in the DIR will require the IR version of Site Server to participate in the IR registry. The DIR and IR Site Server software can reside on the same local server, if desired.

Registry participants may also opt to use software from an IR-Certified Partner to transmit data to the registry.
