- The Procedures Manual shall contain:
- clearly assigned responsibilities and procedures for quality assurance/quality control testing
- procedures for proper use and maintenance of equipment, including the appropriate image receptors and kVp-target-filter combinations for mammography
- mammographic techniques to be used, including pertinent information on positioning, compression, exposure techniques, image quality and average glandular doses with those techniques
- precautions to protect the operator of the equipment, the patient, and individuals in surrounding areas from unnecessary radiation exposure
- policies and employee responsibilities concerning personnel radiation monitoring
- proper maintenance of records, including records of all quality control testing, equipment service and maintenance, and quality assurance meetings.
- There shall be a system in place for reviewing outcome data from mammography, including follow-up re the disposition of abnormal mammograms, and correlation of surgical biopsy results with mammogram reports5,16,17,19,26,27.
- Prior mammograms should be available for comparison when practical17.
- The following quality assurance mechanisms shall be in place:
- double-readings of at least 5%15 of screening mammograms;
- individual monitoring and feedback to radiologists consisting of: (a) referral
rates, (b) outcomes of assessments, including rate of cancers detected per
1000 women screened at prevalence and incidence rounds, rate of small cancers
(≤15mm) detected, and (c) rate of interval cancers15-17,29; and
- inservice education programs and access to professional development workshops related to mammography15,16,19,21,30 (e.g., Level I, II and III Tabar courses in mammography) .
Other possible strategies include:
- monthly site reviews/rounds that include the radiologists and technologists to discuss new breast cancer cases detected, interval cancers, cases where opinions differed on double-reads, etc. 15,16;
- annual multidisciplinary rounds where the radiologists, surgeons, pathologists and family physicians meet to review assessment findings15,16;
- submission of a portion of mammograms for review by external radiologists16,30; and
- Review of Breast Cancer Screening statistics.
