National Mammography Database for Breast Screening

National Mammography Database

American College of Radiology · NCT01900821

This program collects mammogram data from breast imaging centers to give them semi-annual feedback comparing their cancer detection, recall, and positive predictive values to national benchmarks.

What this trial studies

The American College of Radiology's National Mammography Database aggregates data that radiology practices already collect under federal mandates to create national and regional benchmarking reports. Participating centers submit screening and diagnostic mammography metrics and receive semi-annual feedback reports including cancer detection rates, positive predictive value, and recall rates. Participation is free for facilities designated as Breast Imaging Centers of Excellence (BICOE). The project is observational and aims to improve quality of mammography through regular performance comparison rather than changing individual patient care.

Who should consider this trial

Good fit: Ideal participants are breast imaging centers—especially ACR-designated Breast Imaging Centers of Excellence—that routinely perform and can submit screening and diagnostic mammography data.

Not a fit: Individual patients may not receive direct clinical benefit from participation, particularly if their imaging facility does not contribute data or if data-driven changes are not implemented locally.

Why it matters

Potential benefit: If successful, this program could help imaging centers improve screening accuracy and reduce unnecessary recalls, leading to earlier cancer detection and fewer false positives for patients.

How similar studies have performed: Similar national registries and quality-benchmarking programs, such as the Breast Cancer Surveillance Consortium, have been used to track performance and improve mammography quality, so this approach is established.
