The CDS R-SCAN Registry


What is the CDS R-SCAN Registry?

The CDS R-SCAN Registry, now in pilot phase, will become one of seven registries under the American College of Radiology’s National Radiology Data Registry. The CDS R-SCAN Registry provides access to a subset of a facility’s clinical decision support (CDS) data. Currently, participation is available for facilities that have This email address is being protected from spambots.

The data provided correspond to imaging Choosing Wisely recommendations in the R-SCAN program and address the following imaging topics:

  • Uncomplicated headache
  • Low back pain
  • Pre-operative chest x-rays
  • CT angiography for suspected pulmonary embolism
  • Adult minor head trauma
  • Pediatric minor head trauma
  • Febrile seizures
  • Uncomplicated rhinosinusitis
  • Prostate cancer staging for low-risk patients
  • Imaging for patients at low risk for coronary artery disease


What Are the Benefits of CDS R-SCAN Registry Participation?

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


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


How Are a Facility’s CDS Data Obtained?

With an executed National Radiology Data Registry (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.


How Much Does CDS R-SCAN Registry Cost?

Participation in the CDS R-SCAN Registry is free of charge through December 2019 and is made available through a CMS Transforming Clinical Practice Initiative grant, NDSC in-kind services, and additional ACR financial support.
