Report Purpose

The interactive NMD Measures – Aggregate Report Set allows you to view your site’s data in comparison to regional and national peers as well as annual trends.


The report contains many of the statistics available in the quarterly NMD Facility Screening Report and several new calculations and features:

  • Data for the current performance year are refreshed weekly, rather than quarterly

  • Color-coded rankings provide visual feedback with values determined by how well your site’s measure compares to a peer group’s quartiles – e.g. in the Top 25% of all sites in the group, Bottom 25% of all sites, etc.

  • Site rankings compared to the entire NMD are available across years, to identify measures that have improved or declined over time

  • Site performance for selected NMD measures in comparison with ACR BI-RADS Benchmarks as derived from the ACR BI-RADS Atlas, 2013.


Uses of the Report

  • Compare your facility's performance measures such as recall rate and positive predictive values with peers and with ACR BI-RADS® benchmarks to identify potential areas for conducting a quality improvement initiative. The Annual Trends report data can provide insight into how quality improvement initiatives have affected performance over time. 

  • Corporate Accounts with multiple Facility Accounts can now easily assess performance across facilities using the Facility Comparison report tab and variances in performance can be investigated.

New: You can now compare your facility's performance against the ACR BI-RADS®for select measures. See more information below about the BI-RADS Benchmarking tab.


How to Access and Navigate

The report is available in the NRDR portal. Upon selecting the NMD registry in the left menu, locate the heading Interactive Reports in the left menu and select Measures - Aggregate Report.


The About this Report tab provides insight into the reports’ measures and filter use. Upon selecting a report tab, hover over the information icon (blue circle in the upper left corner) to obtain details about maximizing the report’s capabilities.


Report Features

The NMD Measures - Aggregate report set is comprised of multiple tabs with each described below. 


Facility Map

The Facilities Map provides a visual representation of the facilities included in the report's United states Census Bureau Region comparison statistics for a selected year. Each region is color coded.

 

NMD Star Status

The NMD Star Status enables monitoring of a Corporate Account's data submission results with regard to achieving Star Status targets and for earning incentive awards applied toward NRDR annual participation fees.


Peer Comparison Report

The Peer Comparisons Report compares a single facility’s data to the entire registry and to peer groups: 

  • in the same census region (e.g. East North Central, Mountain)

  • of the same facility type (e.g. Academic, Freestanding center)

  • in the same type of location (e.g. Suburban, Metropolitan)

The data table shows each measure, the measure rate, and the numerator and denominator values for the rate. Measure definitions are provided in the Measure Definitions tab. Each site must meet a minimum number of cases for the measurement year to be included in peer group statistics.

Each circle is color-coded to represent the site's ranking compared to the peer group, in terms of quartiles. For example, the top 25% group indicates the facility performed well and was better than 75% of all sites in that group, and the bottom 25% indicates the facility rate was relatively poor, faring worse than 75% of all sites in the group. The information can be downloaded to a PDF following the instructions in the upper-right corner of the report.


Note: Several NMD measures are inverse measures for which being in the bottom 25% indicates better performance.


Additional details are available for each measure comparison by hovering over the circle. In the example, above, hovering the mouse over the circle for Recall Rate shows a detailed bar chart with the facility rate (black dot) and each of the quartiles (differently colored shaded areas) for all facilities in the same Facility Region.


Note: New measures evaluating the timeliness to additional imaging and the timeliness to biopsy were added to the Peer Comparisons report in 2021. See the NMD Measures Definitions tab in this report for more information.  The example below shows a detailed bar chart of a facility's rate compared with all facilities of the same type.


The Annual Trends tab provides rankings over time compared to all NMD facilities meeting the case threshold. Clicking on a measurement name in the table creates detailed graphs for that measure. The line chart compares the facility’s rate (green line) to the registry median (gray line), for each available year. Therefore, when the facility rate is below the registry median line the facility ranking will be in either the Bottom 25% or Bottom 50% to 25%.

Facility Comparisons

The Facility Comparisons tab provides rankings for multiple facilities so you can compare data across facilities. The report also includes total measurement rates, compiled across the selected facilities.

Hovering over a ranking circle provides additional information about the registry percentiles that determined the ranking for that facility and measure.


ACR BI-RADS Benchmarking

The BI-RADS Benchmarking tab displays how a facility's rate compares to the ACR BI-RADS benchmark for the measures: 

  • Recall Rate

  • Positive Predictive Value 1 

  • Positive Predictive Value 2 

  • Cancer Detection Rate



Selecting a measure in the table generates a detailed line chart with facility rates and exam counts by year. The BI-RADS® benchmarks are shaded in the chart to highlight when facility rates fall above or below benchmark values.


Facility Characteristics Report

The Facility Characteristics tab displays the number of sites by Facility Type, Location Type, and United States Census Bureau Region. Each stacked bar chart denotes the number of sites that met the case threshold for the year (blue bars), and the number of sites that fell below the threshold (gray bars).

NMD Measure Definitions

The Measure Definition tab is a list of each NMD measure name and description.
