LCSR Facility Comparisons Report

Article Contents

Report Overview


Get started by signing in to the National Radiology Data Registry (NRDR) portal and selecting the LCSR Facility Comparisons Report in the left menu under Interactive Reports. The report is divided into tabs across the top of the screen. The About this Report tab provides a general overview of the information displayed across all report tabs. In each report tab, hover your pointer over the information icon (blue circle) in the upper left corner to learn more about navigating the report's features.


Note: Several short videos are available to demonstrate how to navigate and use the report:

Report Features

Facilities Map

The Facilities Map provides a visual representation of which facilities are included in the report's Census Division comparison statistics for a selected year. Each division is color coded. LCSR Division Map


Facility Peer Comparisons

The Facility Peer Comparisons tab compares a single site’s data to various peer groups, including sites 

  • in the same Census Division (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), and

  • in the entire registry


The data table shows each measure, the measure rate, and the numerator and denominator values for the rate.  Using the Report Section filter and the Measure filter, you can adjust the amount of information to view.

Note: The LCSR Measure Definitions tab contains a brief description of each measure. More detailed information about each measure is also available here.

 

Each facility must meet a minimum number of cases for the measurement year to be included in peer group statistics. Hovering over the number of cases in a peer group shows how many facilities met the threshold.

LCSR Facility Comparison Rankings

Each color-coded circle represents the site's ranking compared to the peer group, in terms of quartiles. For example, the highest 25% group typically indicates the facility performed well and was better than 75% of all sites in that group, and the lower 25% indicates the facility performance was relatively poor, faring worse than 75% of all sites in the group.


Note: Beginning in 2022, the Screened Population measure now includes results for the 2021 screening criteria recommended by the United States Preventative Services Task Force (USPSTF). The report will continue to show the USPSTF 2013 criteria for the next several years.


Additional details are available for each measure comparison by hovering over the circle. In the example below, hovering the mouse over the circle for Radiation Exposure, Mean CTDIvol – healthy weight (BMI of 18.5 to 24.9) shows a detailed bar chart with the facility rate (dark blue dot) and each of the quartiles (differently colored shaded areas) for all sites in the same Census Division.

Each shaded area represents the range of rates for one-quarter of the facilities in the Pacific Census Division in 2021 that met the case threshold:

  • The leftmost shaded area shows 25% of sites had a rate of 1.7 or lower

  • The next shaded region is for sites that had a rate between 1.7 and 2.3

  • The third from the left shaded area is for sites with a rate between 2.3 and 2.9, and

  • The rightmost shaded region shows 25% of sites with rates greater than 2.9

Note: Some measures, such as volume CT dose index (CTDIvol) and dose length product (DLP), are inverse, so lower rates are better. For other rates, such as smoking cessation counseling, higher rates are better.


Note: The registry median (gray line), also known as the 50th percentile, represents the midpoint across all facilities; that is, half of the facilities in the LCSR have a rate below this value, and half have a rate above this value.

 

Hover over a colored ranking circle or over the registry data point (indicated by a dot with a numbered value) in the line chart to see details for that year, including the registry 25th, median (50th), 75th, and 95th percentiles.

 

The bar chart shows the number of cases for the facility for the selected measure by year, to provide some context to the facility rate and ranking.


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.

 

Lung-RADS Comparison

The Lung-RADS Comparison tab shows the percentage of lung cancer screening exams by Lung-RADS category for the year and facilities selected (light blue bars) and for their total (green bar).  Use the comparison filters (shaded in gray), to view Lung-RADS reporting results compared with the entire registry or with facilities in a selected Census Division, Facility Category, or Location Type.  Use the Statistic filter to select a comparison percentile.  In the screenshot below, the Lung-RADS reporting breakdown for two facilities is shown compared with all academic facilities submitting data for 2021. The example shows the median percentile for reporting Lung-RADS 2 exam results among academic facilities in 2021 is 59.8% demonstrating the two facilities are well above the median for this Lung-RADS category.



Adherence to Annual Screening

The Adherence report tab provides insight into the percent and number of patients who had a previous screening exam of LungRads 1 or 2 and return for their annual screen. The report year is the date a patient returned for a screening exam if they returned within 15 months. You can view facility performance results by the comparison categories of census division, facility type, location type, or the full registry.  You can also select a percentile for the comparison category that displays as a red line on the bar charts.


The blue bars in the first chart represent the percentage of patients who return for an annual screening exam within 11 to 15 months. The green bars show the total for all selected facilities.   The example below displays the comparison data for three academic facilities with the red line showing the 50th percentile, or median, of all academic facilities submitting registry data. Hovering over the blue bar for a facility shows more specific details.  

Clicking a blue bar in the first chart enables you to drill into the adherence performance for a single facility.  Clicking a blue bar in the second chart displays the individual cases for the facility for a specific time period to track the percentage of patients who return for an annual screening exam within 16 to 24 months or greater than 24 months after their last annual exam.  Patients who are overdue (have not returned within 11 to 15 months) for a follow-up exam are tracked in the No followup (overdue) column until they return.

Facility Characteristics

The Facility Characteristics tab displays the number of sites by Facility Type, Location Type, and Census Division. 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).
