Information
for mammography facility personnel, inspectors, and consumers about the implementation of the Mammography Quality Standards Act of 1992 (MQSA) |
PERFORMANCE EVALUATION OF ACCREDITATION BODIES UNDER THE MAMMOGRAPHY QUALITY STANDARDS ACT OF 1992 as amended by the MAMMOGRAPHY QUALITY STANDARDS REAUTHORIZATION ACT OF 1998 |
January 1, 2004 through December 31, 2004
Executive Summary
The goal of the Mammography Quality Standards Act (MQSA) of 1992, as amended by the Mammography Quality Standards Reauthorization Act (MQSRA) of 2004, is to ensure that facilities meet standards for performing high quality mammography. The Food and Drug Administration (FDA) administers MQSA. Among other things, MQSA provides for the FDA-approved accreditation bodies (ABs) to evaluate and accredit mammography facilities against quality standards. Based on successful completion of this process, FDA then issues certificates to the facilities so that they can legally operate. MQSA requires annual reports to Congress on AB performance. This ninth annual report covers the period from January 1 through December 31, 2004.
To implement the MQSA (Public Health Service Act section 354, 42 USC section 263b), FDA issued final regulations that became effective on April 28, 1999 (21 CFR Part 900). The final regulations state that FDA’s evaluation of ABs shall include a(n):
Status of Accreditation Bodies
FDA approved the American College of Radiology (ACR), a private, nonprofit organization, as well as the states of Arkansas, Iowa, and Texas under the MQSA and the final regulations. Since each AB’s approval expires on April 28, 2006, they will begin the renewal process in the fall of 2005.
FDA approved the State of California (SCA) under the interim MQSA regulations in 1994. Then, in 1998, the SCA applied for AB status under the final regulations. Despite the collaborative efforts of FDA and the SCA, the State was unable to develop its MQSA accreditation program to achieve approval under the final regulations. Therefore, on May 5, 2004, the SCA withdrew its application to become an FDA-approved AB under the MQSA final regulations. Through its withdrawal, the SCA relinquished its authority and responsibilities under the MQSA. Section 900.13(b)(1) and (2) (under 21 CFR Part 900) allows certificates of facilities previously accredited by a withdrawn AB to remain in effect for up to one year from the date of the withdrawal of approval, unless FDA determines that there are public health issues or that the AB fraudulently accredited any of its facilities. As a result of the SCA’s withdrawal, all SCA-accredited facilities were required to apply for accreditation from the ACR no later than May 5, 2005. On May 7, 2004, and May 13, 2004, the SCA and the FDA, respectively, notified all SCA-accredited facilities (465) of the State’s withdrawal and the MQSA requirement that these facilities obtain accreditation from the ACR within one-year. As of May 5, 2005, all SCA facilities had transitioned to the ACR.
Core Functions of the Accreditation Bodies
The ABs review documentation and clinical1 and phantom2 images that are submitted by mammography facilities for accreditation purposes. On determining that facilities meet specific requirements, the ABs make a positive accreditation decision. FDA then certifies the facilities based on that accreditation.
FDA evaluates the ABs on a number of elements, but concentrates on these core AB functions:
Performance Indicators
FDA evaluates the performance of its ABs through:
To assess overall performance of the ABs, the agency evaluates information in various areas: administrative processes, reporting and record keeping processes, accreditation review and decision-making processes, AB on-site visits to facilities, random clinical image reviews, additional mammography reviews, and accreditation revocations and suspensions. FDA’s evaluation includes on-site visits to the ABs and ongoing written and oral communications with the ABs.
Findings from CY 2004 AB Performance Evaluations
The following items are highlights of FDA’s CY 2004 report to Congress:
FDA and the ABs, working in partnership with the certified mammography facilities in the United States, as well as the states participating in inspections and other MQSA activities, are ensuring quality mammography across the Nation.
1Clinical image review: the facility must submit
to the AB two cases (one fatty breast and one dense breast) to be reviewed and
scored by an AB panel of trained interpreting physicians. Each case consists
of four views, two craniocaudal and two mediolateral oblique views.
2 Phantom images are x-ray films of plastic objects
that contain various simulated abnormalities of breast tissues. Phantom images
are used to test the ability of the equipment to discriminate abnormalities.
