Report Features

Get started by selecting one or more Corporate Account, at least one corresponding Facility, and a time frame of interest using the Exam From - To filter.

Exam Search Tab

The report enables you to query exam data for one or more facilities using a variety of filters:

  • Modality, Physician NPI, CPT Code, and Study Name: Pinpoint areas to further explore using the filters' criteria.

  • Place of Service: Sort performance by Ambulatory, Inpatient, and ED care settings.

  • Number of Readers: View the impact on turnaround times of having more than one reader, e.g., a resident and attending physician.

  • Sort Exams by: View performance results sorted by date or turnaround time.

  • Turnaround (filter): Filter exams by the report turnaround time, in hours. 

The sample report below shows performance results for x-ray wrist exams submitted in the last quarter of 2022. The turnaround time sliding filter is set between -0.3 and 72 hours. Hover over a value in the Turnaround Time (hrs.) column to see the details of the calculation, including the date the final report was signed.

The turnaround time filter is a useful way to identify exams with unusual values, such as very high turnaround times or negative times. The sample report to the left shows the table sorted by date. Turnaround times, in hours, are displayed both numerically and with a bar to help highlight larger values. The bar is light blue for positive turnaround times and red for negative values.

Note: Negative turnaround times highlighted in red likely indicate incorrect data.


The report can also help you investigate performance for a specific setting and type of exam. The example to the right shows turnaround times for trauma emergency services.

Turnaround Time Summaries Tab

This report can help you quickly identify turnaround time performance anomalies or patterns by reviewing data across a variety of variables. The report can also provide insight into the effect of new processes and performance improvement efforts. For example, the report can help you assess the impact of new scheduling methods, changes in staffing levels, and new equipment. Performance trends can be delved into for a specific period for one or more facilities, modalities, and exam types.

The tables display the number of exams and average turnaround time by Facility ID, NPI, Modality, Place of Service, and Number of Readers. 

Rows in each table are sorted by descending average turnaround time. The light gray bars highlight exam volumes and the blue bars indicate turnaround times. All summary tables are interactive; clicking on a row will filter the rest of the report, including the exam table. For example, click on ED in the Place of Service Summary Table asshown in the example below to display data for the ED only in all other tables and charts.

To undo a selection, click it again or click the Undo button in the bottom left corner of the report.

The Sort Exam Table filter sorts the exams by turnaround time or by date.

The heat map calendars display average turnaround times by the date exams are completed and by the date, the corresponding final reports are signed for the time period selected in the Exam From and To filter. Blue denotes dates with average shorter turnaround times and red indicates average longer times. 

Note: Each heat map calendar has a different legend as the ranges may differ. Click a date in the Date Exam Completed calendar to filter the report.  Scroll through the Date Final Report Signed Calendar to view the corresponding dates when the final reports were signed or through the GRID Exam Search Table for more detail.   

The sample report presented below shows how selecting a day in the Data Exam Completed calendar updates the report.

GRID 2.0 Measures Tab

The report displays aggregate rates for each GRID 2.0 measure for which the site is submitting data. Click a measure in the table to display the Exam Detail Table that lists all of the exams that contribute to the measure's rate. The exam detail legend denotes the color coding used in the table.
