THE MAMMOGRAPHY AUDIT - A PRIMER FOR THE MAMMOGRAPHY QUALITY STANDARDS ACT (MQSA)

The medical audit of a mammography practice is a recognized method for evaluating mammography and the accuracy of mammographic interpretatio n [1-4]. As such, portions of the audit will become integral to the qu ality assurance activities of every mammography practice under the Mam mography Quality Standards Act (MQSA) of 1992, administered by the Foo d and Drug Administration (FDA). The FDA Interim Rules, which became e ffective October 1, 1994, state that ''each facility shall establish a system for reviewing outcome data from all mammography performed, inc luding follow-up on the disposition of positive mammograms and correla tion of surgical biopsy results with mammogram reports'' [5]. It is ex pected that the proposed final rules, due to be released for public co mment in 1995, will require collection of additional data for medical audits (public meeting of the National Mammography Advisory Committee, May 3, 1994). Although most mammography practices are now collecting clinical outcomes data on abnormal mammographic examinations, very few have established an organized and deliberate system of data collectio n necessary for a more complete mammography audit [6]. A detailed disc ussion of and recommendations for such an audit were recently publishe d as part of the Quality Determinants of Mammography Guideline by the Agency for Healthcare Policy and Research (AHCPR) [7]. As members and consultants on the multidisciplinary panel that produced the guideline , we offer the following review of the various elements, definitions, and processes of the mammography audit. This is intended as a primer f or all radiologists who will be performing some of the same audit acti vities for the MQSA.
