Proposed Changes to IAC Vascular Testing Standards Now Open for Public Comment - COMMENT PERIOD NOW CLOSED

APRIL 5, 2017 | In keeping with the IAC's continued commitment to streamlining and simplifying the accreditation process, we are pleased to announce that the public now has the opportunity to comment on proposed changes to the IAC Standards and Guidelines for Vascular Testing Accreditation.

The Standards are reviewed periodically by the IAC Vascular Testing Board of Directors and revised as needed. As a component to the accreditation process, proposed Standards that have been approved by the Board of Directors are then posted to the IAC website for a 60-day public comment period. These proposed Standards include changes to the current Standards and/or the addition of new Standards

Beginning April 5, 2017, the public may visit the IAC website at intersocietal.org/iac/comment_period.htm#vascular to comment on any of the proposed Standards until June 5, 2017. In order to provide comments, the IAC Comment Form must be completed and submitted electronically by the provided deadline.

To Submit a Comment on Proposed Standards

  1. Visit the IAC website at intersocietal.org/iac/comment_period.htm#vascular;
  2. Select the proposed Vascular Testing Standard on which to comment;
  3. A window will expand with the description of the Standard and the proposed change on the left;
  4. On the right, fill in your name and comment in the boxes provided;
  5. Hit Submit.

At the close of the comment period, the IAC Vascular Testing Board of Directors will review any submitted comments, consider modifications as needed and vote for final approval of the Standards. Facilities are notified of changes to the published Standards, and the most current version of the Standards can be viewed or printed from the IAC Vascular Testing website at www.intersocietal.org/vascular/seeking/ vascular_standards.htm.

Update on the IAC Vascular Testing Carotid Diagnostic Criteria Project

MARCH 2017 | In 2014, IAC Vascular Testing published a white paper document regarding carotid diagnostic criteria and its activities in this arena1. The document discusses the variability in carotid stenosis interpretation across accredited facilities and summarizes data from surveys of IAC accredited laboratories that support efforts toward standardization. The document describes plans to internally validate carotid diagnostic criteria for use in IAC accredited facilities, including commissioning of a carotid research committee.
As an update, the IAC Vascular Testing Carotid Research Committee met on February 17, 2017 to review progress of its diagnostic criteria project. Eleven clinical sites have submitted protocol-directed case study materials. At this time, all 210 complete case studies (bilateral carotid duplex studies and catheter-based angiograms) have been collected and technical data has been abstracted from these studies. The angiograms and ultrasounds are now undergoing interpretive review. Study data will be analyzed in 2017, with plans for publication and dissemination of the study results in 2018. 
The IAC will continue to provide updates regarding this project as it moves ahead. With regard to which carotid diagnostic criteria to use at the present time, IAC Vascular Testing continues to recommend that in the absence of internally validated single set of diagnostic criteria, facilities should consider the use of one single set of standardized diagnostic criteria: The Society of Radiologists in Ultrasound (SRU) Criteria for Carotid Stenosis Interpretation 2. Facilities that have internally validated their own criteria may continue to use these criteria.

Participating sites in the diagnostic criteria research project:
Cleveland Clinic (Heather Gornik, MD, RVT, RPVI; Alia G. Grattan, RDMS, RVT)
Novant Health Heart and Vascular Institute (Kelly M. Estes RT(R), RDMS, RVT, RDCS)
Riverside Radiology (Lucy LaPerna, DO, FSVM, RPVI, RVT)
TriHealth (Joann Lohr, MD, FACS, RVT)
University at Buffalo (Adnan Siddiqui, MD, PhD)
University Hospital and Clinics (Michel E. Comeaux, RN, BSN, RVT, RDMS, FSVU)
University of Maryland (Michael Lilly, MD, RVT, RPVI)
University of Miami (Tatjana Rundek, MD, PhD)
University of Pittsburgh (Steven Leers, MD, RVT)
University of Southern California (Susana Robison, BS, RVT, FASE)
University of Washington (R. Eugene Zierler, MD, RPVI)
