CDS R-SCAN Registry

The CDS R-SCAN (Radiology Support, Communication and Alignment Network) Registry, now in pilot phase, will become a registry under the ACR’s National Radiology Data Registry (NRDR). The CDS R-SCAN Registry provides access to a subset of a facility’s CDS data. The data provided correspond to imaging Choosing Wisely recommendations in the R-SCAN program.

The registry is a mechanism for radiologists and referring clinicians to collaborate on improving the ordering of imaging exams that add value to patient care. By reviewing CDS R-SCAN Registry reports, imaging areas that could benefit from educational intervention can easily be identified. Additional benefits include:

  • Engagement of referring physicians in a targeted quality initiative using CDS to demonstrate how consultation of appropriate use criteria demonstrates improvements made in the ordering of imaging exams
  • Access to reports that provide quantitative data about improvements achieved and track that achievements are maintained over time
  • Fulfillment of “Improvement Activity” credit requirements for practices participating in the MIPS track of the CMS Quality Payment Program
  • Access to an archive of educational material for each R-SCAN topic including activities that award CME and provide hands on experience with clinical decision support

How to Participate

  • Currently, participation is available for facilities that have CareSelect Imaging/ACR Select provided by the National Clinical Decision Support Company (NDSC).
  • Participation is at no cost through December 2019 and is made available through a CMS Transforming Clinical Practice Initiative grant, NDSC in-kind services, and additional ACR financial support.
  • Interested facilities will need to complete participation agreements and attend a webinar demonstration.
  • Contact us at to get started.

How to Submit Data

With an executed NRDR Participation Agreement/Business Associate Agreement, a facility can submit its imaging CDS data to the registry. Data is transmitted to the ACR using Web services from the facility’s CDS or electronic health record (EHR) system. Facility designated representatives are granted access to view their facility’s data.

Sites that have integrated CareSelect Imaging/ACR Select into their EHR can start participating in the registry during the pilot phase currently in progress.

What Registry Data Are Provided to Participants?

The CDS R-SCAN Registry reports provide the following filters for obtaining feedback information:

  • R-SCAN topics
  • Imaging clinical indications
  • Ordering departments, practices, or groups along with a breakdown of the respective number of cases ordered
  • Date range
