The CDS R-SCAN Registry

What is the CDS R-SCAN Registry?

The CDS R-SCAN (Radiology Support, Communication and Alignment Network) Registry provides facilities with access to their image-ordering clinical decision support data that correspond to imaging Choosing Wisely recommendations in the R-SCAN program, CMS Priority Clinical Areas, and several other imaging areas.

The registry data can identify imaging exam ordering patterns for some of the most commonly ordered exams to pinpoint areas where best practices are being followed as well as areas in need of improvement.  View a video of the CDS R-SCAN Registry interactive report.

Participation benefits include:

  • Access CDS data with no facility IT set up required – data are sent to the registry from the CDS vendor directly to the ACR.
  • Review interactive reports that provide quantitative data about improvements achieved and monitor how well achievements are maintained over time. Reports contain filtering and drill-down functionality by a variety of dimensions including R-SCAN topic, imaging clinical indications, ordering department/practice/groups, etc. to help draw insights from the data. Currently, reports are site-specific; registry comparison reports are not yet available.
  • Review image-ordering adherence to the ACR’s Appropriateness Criteria for a growing list of imaging areas, both facility-wide and by service line.
  • Gain insight into trends in imaging exam volume for a specific date range and over time.
  • Associate the CDS data with R-SCAN topics to conduct an R-SCAN practice quality improvement project -- a mechanism for radiologists and referring clinicians to collaborate on improving the ordering of imaging exams that add value to patient care. Completing an R-SCAN QI project affords clinicians: 
  • Fulfillment of Improvement Activity credit requirements for practices participating in the MIPS track of the CMS Quality Payment Program
  • Qualification for Practice Improvement CME (up to 20 CME credits).
  • 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?

Through the integration of CareSelect Imaging into a facility’s electronic health record (EHR), CDS transactional data are stored in the NDSC database and transmitted to the ACR using an NDSC-developed web service. No additional IT support is required. 

Transmissions from NDSC to CDS R-SCAN include procedure-related data only, along with patient age; no Protected Health Information (PHI) is sent to the registry. Once data are stored in the database only facility-designated representatives are granted access to view their facility’s data.

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.
