Legislative and regulatory mandates for mammography quality assurance.

The current practice of screening mammography in the United States has been the focus of numerous legislative and regulatory mandates at the state and federal levels, both in terms of increasing access to age-eligible women and elevating the quality of mammographic imaging. Several parameters have emerged as central to a comprehensive mammography quality assurance program: (1) equipment specifications, (2) equipment performance testing including radiation dose limits, (3) facility quality assurance procedures, and (4) personnel qualifications. In 1992, Congress enacted the Mammography Quality Standards Act (MQSA) (P.L. 102-539) to address the problem of differences in mandated standards across states. By October 1994, all facilities will be required to comply with interim MQSA regulations which were released in December 1993. However, depending upon the specific requirements of applicable state standards, the extent and nature of modifications of existing quality assurance procedures will differ for facilities across states as they attempt to come into compliance with uniform Federal standards. In addition, because some provisions within state standards are likely to be more stringent than Federal standards, some level of variation will persist. This paper reviews the components of mandated standards established by states and the standards established by other organizations, including the Federal Government, prior to the MQSA interim regulations. This review will provide an understanding of the highly technical and complicated requirements surrounding mammography quality assurance.
