The Summary Comparison report allows you to query your facility’s data and compare it to the entire registry and similar facilities.


The report is available via the Summary Comparison link under the Interactive Reports menu. You must first select one Facility ID, a Quarter, and at least one Exam Report Name to generate the report.


The rest of the report filters and parameters are set to default values and may be changed at any time:

  • DIR Measure (unit of measure): Dose Index type CTDIvol, DLP or SSDE; either maximum value across scans or total for the exam

  • Exam Year

  • Quarter

  • Age Group

  • Exam Report Name

  • Peer Group, for comparisons with the entire registry, same location type, same Census division, and same facility type

  • Exam Count Threshold: sets criteria for minimum number of exams


The report generates a summary table with columns for the number of exams (N), and quartiles for the selected DIR measure by exam and age group.

DIR Interactive Reports - Sample Summary Comparison


Comparisons are listed in rows below the facility row. Facility rows with median values below the 25th percentile for the entire DIR registry or above the 75th percentile are highlighted.


Selecting the Corporate Account from the Facility filter aggregates data for all facilities within that account.

Note: All DIR Sites is the only Peer Group available for Corporate Account-level data because facilities within the account may have different peers - e.g. two different facilities may have two different facility types, location types, etc.
