Abstract：
OBJECTIVE: To evaluate the effects of the Enhancing Quality Using the Inspection Program (EQUIP) on quality control (QC) and quality assurance (QA) at an academic medical center.
METHODS: EQUIP audit logs for technologist image quality review as well as mammography unit QA and QC formed the basis for study data. One randomly selected screening mammogram was evaluated by the lead interpreting physician (LIP) using EQUIP criteria for each technologist for each imaging site worked, initially semiannually and then monthly. One randomly selected screening mammogram interpreted by each interpreting physician (IP) for each imaging site was evaluated on a semiannual basis. Quarterly, the LIP reviewed QA and QC logs for each mammography unit with deficiencies further investigated.
RESULTS: Of 214 965 eligible screening mammograms performed, 5955 (2.8%) underwent EQUIP image quality review. Five were found to be technically inadequate (0.08%, 5955/214 965). The LIP identified 20 significant interpretive differences compared with the clinical interpretation resulting in 10 biopsies and 7 previously undetected malignancies, with supplemental cancer detection rate of 1.2/1000 cases reviewed. Two hundred ninety mammography unit QA/QC reviews identified 31 potential deficiencies, 29 of which were due to human documentation error (93.4%).
CONCLUSIONS: EQUIP review of both IP and technologists\' quality and mammography unit QA/QC logs as performed identified few deficiencies. EQUIP policies should be evaluated at each institution and modified to best utilize resources and provide opportunities for meaningful quality improvement. Although not an EQUIP focus, supplemental cancer detection was observed as might be expected with double reading.

摘要：
目的：在学术医疗中心评估使用检查计划（EQUIP）提高质量对质量控制（QC）和质量保证（QA）的影响。
方法：技术专家图像质量审查的EQUIP审计日志以及乳房X线照相术单元QA和QC构成了研究数据的基础。由首席解释医师（LIP）使用EQUIP标准对每个成像部位的每个技术专家进行评估，最初每半年一次，然后每月一次。每半年评估一次由每位解释医师（IP）对每个成像部位进行解释的随机选择的筛查乳房X线照片。季度,LIP审查了每个乳房X线照相术单元的QA和QC日志，并进一步研究了缺陷。
结果：在进行的214965次合格筛查乳房X线照片中，5955(2.8%)行EQUIP图象质量检讨。五个被发现在技术上是不够的(0.08%,5955/214965)。与临床解释相比，LIP发现了20个显着的解释差异，导致10个活检和7个以前未发现的恶性肿瘤。以补充肿瘤检出率1.2/1000例复查。二百九十个乳房X光检查单位QA/QC审查确定了31个潜在缺陷，其中29个是由于人为文档错误（93.4％）。
结论：对知识产权和技术专家的质量和乳房X线照相术单元QA/QC日志进行的EQUIP审查发现了很少的缺陷。EQUIP政策应在每个机构进行评估和修改，以最佳利用资源并提供有意义的质量改进机会。虽然不是EQUIP焦点，观察到补充的癌症检测，这可能是双读数所预期的。
