NMD Facility Screening Report
Modified on: Thu, 18 Jan, 2018 at 8:46 AM
The NMD Facility Screening Report compares your facility’s data to peer and national benchmarks, helping you identify opportunities for improvement.
Reports are posted quarterly with preliminary data for Jan. – Mar. and Jul. – Sep.
Click the Aggregate Reports menu item in the NMD Reports menu to generate a table of reports available for download. A sample report is available here.
NMD Active Facilities Map
The Active Facilities Map displays the geographic distribution of facilities that contributed data for the given reporting period, grouped by Census Region.
The map provides a visual representation of which facilities are included in the Registry statistics the report.
Bar charts provide frequency distributions for the NMD registry for several characteristics, including:
Census Region, and
Annual Procedure Volume
The sample chart, to the right, shows the distribution of facilities by Annual Procedure Volume; the sample facility’s volume of < 5,000 exams per year is indicated in the chart title.
Measure Definitions and Sections
The Measures Definitions table provides a brief description of each measure listed in the report.
Data are grouped into two sections:
Section 1 contains data for exams with at least 365 days of follow-up data. Facilities with no exams having at least 365 days of follow-up data receive only NMD aggregate benchmark data in this section but do have preliminary data in Section 2.
Section 2 includes preliminary data on exams performed in the most recent 12 months.
Facility data are shown in three sets of comparison tables:
Facility data compared to All Facilities (i.e. entire NMD registry) and Breast Cancer Surveillance Consortium (BCSC) benchmarks
Facility data compared to similar facilities, as defined by facility type and annual procedure volume
Facility data compared to similar facilities as defined by location and Census Region
Comparison Bar Charts
A series of bar charts provides data for seven measures, grouped into the following graphs:
Recall Rate and PPV2
Cancer Detection Rate (CDR), and
Biopsy Results (Biopsy Positive, DCIS, Invasive Cancer, Minimal Cancer)
Each chart plots your facility’s rate along with rates for similar facilities (by location, type, volume, and Census region), the entire NMD registry, and BCSC benchmarks.
Histograms and Box Plots
For each measure, there is a histogram plotting the distribution for that measure across all facilities in NMD, with your facility’s rate plotted as a vertical line. Data for other facilities are shown in box-and-whiskers form, with max, min, mean, median and quartiles for each comparison group.
For comparison purposes BCSC benchmarks are provided including the mean, median, quartiles, and 10th and 90th percentiles. Benchmark charts are provided once, in Section 1, because Section 2 is comprised of Preliminary data.
Trend charts plot data by year, from the start of the NMD registry. Facility data are shown along with data for similar facilities and the entire registry.
Clinical Demographics Tables and Charts
The last set of tables and charts provides distributions for various clinical demographics including age, BI-RAD assessment category, family history of breast cancer, and symptoms reported. Data for similar facilities and the entire registry are included.
