The CT Administrative Aggregate Report enables users to analyze performance and drive improvement in CT imaging. The report provides insights about:
The report is specially formatted for viewing and downloading aggregated dose performance data for further analysis and report sharing.
How to Access
Log into the NRDR Portal and access the CT Administrative Aggregate Report in one of two ways:
Report Help Features
The report is divided into five tabs called dashboards across the top of the report. The About this Report dashboard provides a brief description of each dashboard, information about the measures and inclusion criteria, and a few pointers for navigating across the dashboards.
In each dashboard, hover your pointer over the information icon (blue circle) in the upper left corner for a brief description of the dashboard's purpose and how to populate it with data. Once the report is populated with data, click the Help link to bring up an overlay with specific report navigation instructions. The Read about this report link opens this Knowledge Base article and the Feedback link opens a user input form.
Aggregate Comparisons Dashboard:
Highlights dose index outliers aggregated by either the Exam Short Name or Body Area level using the Exam Aggregate Level filter and enables comparison of one or more facilities to the registry and a selected Peer Group such as location type or facility category. The date From-To filter enables targeting specific periods, for example, to observe how a protocol change affected dose performance. The Statistics filter and Comparison Standing filter allow you to select performance parameters of most interest. Facility median dose index performance is compared to the registry and reflected in the DIR Standing column. Percentiles reflect the proportion of facilities with median values falling below the specified value. For example:
25th Percentile: 25 percent of facilities have a median dose index falling below this value.
Median: 50 percent of facilities have a median dose index falling below this value.
75th Percentile: 75 percent of facilities have a median dose index falling below this value.
The screenshot example of the Aggregate Comparison Dashboard below shows the dose index CTDIvol results for adult Chest-Abdomen-Pelvis exams have a comparison standing above the 75th percentile compared to the registry and to the selected peer group.
Trend Data Dashboard:
Allows for viewing the performance of one or more facilities over time using the Time Periods filter to select a Semiannual, Quarterly, or Monthly view option. The report provides performance data for one or more facilities in a downloadable format so that users can create trend charts.
Short Name Lookups Dashboard:
Shows how a facility's exams map to Radlex Playbook IDs (RPIDs) and the report's Exam Short Names. Using this report helps identify mapping inconsistencies across facilities.
