The responsibilities of the Co-Chairs of the LOINC/RadLex Committee include:

  1. Organizing the Committee
  2. Assist in facilitating logistics for Committee meetings (supported by the Secretariat)
  3. Conducting Committee meetings
  4. Preparing and announcing agendas
  5. Supporting the Secretariat in documenting and disseminating meeting minutes
  6. Being a consistent active participant in Committee discussions


The Regenstrief Institute and the Radiological Society of North America (RSNA) jointly serve as the Secretariat for the LOINC/RadLex Committee.

Officer Selection

The LOINC/RadLex Committee will be co-chaired by a Regenstrief appointee and an RSNA appointee.

Active officers must be Members of the LOINC Committee. Should a seated officer experience a change in membership status due to either the loss of individual membership or loss of membership by their organization; that individual will be removed as an officer. The Secretariat holds the responsibility for filling the vacant officer role.


Members of the LOINC/RadLex Committee will be drawn from stakeholder organizations. Members of the LOINC/RadLex Committee must meet the general qualifications for membership, and will hold membership in the overall LOINC Committee.

Each co-chair will appoint up to three (3) additional committee members. Additionally, the co-chairs, by mutual agreement, will select up to three (3) at-large members representing other stakeholder organizations. The total number of committee members will thus not exceed eleven (11).


The LOINC/RadLex Committee will meet at least once a year. The LOINC/RadLex Committee may hold additional meetings and teleconferences with the agreement of at least one co-chair. The LOINC/RadLex Committee meetings will be open to all interested participants.


The decisions of the Committee will be made by consensus whenever possible. The following decisions will be made by a majority vote of the voting members at a meeting of the Committee at which a quorum is present:

  1. Whether to include or exclude terms from the LOINC/RSNA Radiology Playbook
  2. The content and format of the LOINC/RSNA Radiology Playbook term metadata
  3. Changes to the information model for the LOINC/RSNA Radiology Playbook

A quorum which consists of a majority of Committee members with active voting rights will be required for the Committee to take action.
