The NMD Data Quality Report provides summary and detailed tables for a selected History ID. Use this report to make sure the data you submitted to the NMD are accurate and complete. While the report includes a wide range of information, it does not show all submitted data and does not display performance measures. Its primary purpose is to help users confirm the integrity of their data.

Access the report as follows:

1. Click Reports in the top menu from any page in the NRDR portal.

2. Click the drop-down arrow next to NMD in the left menu.

3. Click Data Quality.

Data for all tabs are determined by the Facility and History ID selected from the Summary of Records tab. The report includes all History IDs uploaded within the past 365 days for the facility selected. 

The report includes data for both NMD file versions 2.x and 3.x. Data are grouped into the tabs described below, with data elements and formatting depending on the NMD file version submitted.

To view the report, choose the Facility ID whose data you want to view by clicking the Facility ID in the drop-down menu on the Summary of Records tab:

Then select the desired history ID from the History ID drop-down menu:

At the top of the Summary of Records page is a record count by modality. 

It is recommended that you verify that the following is what you expect:

• The range of exam dates. In this example, the range is from February 4, 2019, to April 18, 2020.

• The number of records, that is, the number of exams reported.

• The number of exams recalled, that is, the number of screening exams with an abnormal interpretation.

• The number of cancers, that is, the number of records with lesions classified as malignant.

• The number of records with no NPI.

  Records with no NPI will not be included in physician-level reports.

Check the Missing and Unknown Values table to make sure that the optional fields you intended to report were actually reported:

You should also check the count of required fields that have unknown values. A high incidence does not necessarily indicate a problem. For example, in the table above, a 63.8% unknown rate for Malignancy Type makes sense, because most of the records did not report a malignancy.

The Errors/Inconsistencies tab shows data elements with incorrect or inconsistent data. You can click the Patient NRDR ID to see additional information about the exam.

For security reasons, the patient name that corresponds to the Patient NRDR ID is not included. You can find the patient name as follows:

• Click the Manage Patients link on the NRDR home page.

• Click the + to the left of the Filter.

• Enter the Patient NRDR ID in the Patient ID field.

The Data Frequencies tab shows single-variable frequencies of selected data elements.

The Patient Demographics tab shows exam frequencies for patient sex and age, as well as height and weight (2.x file formats only).

The Cancer Summaries tab shows frequencies for selected cancer data elements.

The Indication and Assessment tab shows bar charts for combinations of Indication of Exam and Assessment Category.
