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. 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 an interactive report (see video example) that provides quantitative data about improvements achieved and monitor how well achievements are maintained over time. The report 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, the report if facility-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:

How to Participate

  • Currently, participation is available for facilities that have CareSelect Imaging/ACR Select provided by the National Clinical Decision Support Company (NDSC).
  • During the period of measure and benchmark report development planned for 2020, the ACR will continue to provide participation in the CDS R-SCAN registry at no cost.
  • Interested facilities will need to complete participation agreements and attend a webinar demonstration.

How to Submit Data

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.
