Performance Benchmarks for Diagnostic Mammography

Sickles EA, Miglioretti DL, Ballard-Barbash R, Geller BM, Leung JWT, Rosenberg RD, Smith-Bindman R, Yankaskas BC. Performance benchmarks for diagnostic mammography. Radiology 2005;235(3):775-790. [AbstractExternal Web Site Policy]

In the United States, a Food and Drug Administration (FDA) regulation requires limited auditing of clinical outcomes for all screening and diagnostic mammography examinations that have been assessed as either suspicious for malignancy or highly suggestive of malignancy. More comprehensive auditing is performed by many mammography facilities in both the United States and other countries. Auditing is thought to be a useful quality assurance procedure, providing performance feedback to both mammography facilities and individual interpreting radiologists.

The following tables and figures contain a range of performance parameters pertinent to the comprehensive auditing of diagnostic mammography examinations. These tables and figures contain supplemental information from the published paper listed above. (Note: These data have not been submitted for peer review.) Pooling of these data from BCSC registries provides by far the largest reported experience involving diagnostic mammography practice, from which reasonable and realistic performance benchmarks may be derived.

Tables

The latest estimates for the following tables are based on 363,048 diagnostic mammography examinations performed between 2004 and 2008.

Figures

The following figures display smoothed plots of frequency distributions for performance parameters as a function of indication for examination.
