目的：回顾性评价放射科医生在筛查性乳腺X线摄影检查中的表现结果范围，使用美国的代表性样本。S.材料和方法：获得了机构审查委员会的批准，并且研究符合HIPAA。根据机构审查委员会指南获得或未获得知情同意书。从1996年至2002年之间获得的188个乳腺摄影设施和807名放射科医生的数据进行了分析，从乳腺癌监测联盟（BCSC）的六个登记处。贡献的数据包括人口统计学信息、临床结果、乳腺X线摄影解释和活检结果。计算的测量值为筛查乳腺X线摄影（PPV 1）的阳性预测值（PPV）、活检建议（PPV 2）、进行的活检（PPV 3）、召回率、癌症检出率、平均癌症大小和癌症分期。放射科医生的性能数据呈现为第50（中位数），第10，第25，第75，和第90次扫描，并通过使用平滑curve.Results图形演示：有2 580 151筛选乳腺X线摄影研究1 117 390名妇女（年龄范围，< 30 to >= 80岁）。中间50%放射科医生的性能结局的平均值和范围如下：召回率，9.8%和6.4% - 13.3%; PPV 1，4.8%和3.4% - 6.2%; PPV 2，24.6%和18.8% -32.0%。平均癌症检出率为4.7每1000，和浸润性癌症的平均大小为13毫米。的范围内的性能结果为中间80%的放射科医生也presented.Conclusion：社区筛查乳腺摄影性能测量的癌症结果的大多数放射科医生在BCSC超过性能的建议。然而，几乎一半的放射科医生的回忆率高于推荐率。
Purpose: To retrospectively evaluate the range of performance outcomes of the radiologist in an audit of screening mammography by using a representative sample of U. S. radiologists to allow development of performance benchmarks for screening mammography.Materials and Methods: Institutional review board approval was obtained, and study was HIPAA compliant. Informed consent was or was not obtained according to institutional review board guidelines. Data from 188 mammographic facilities and 807 radiologists obtained between 1996 and 2002 were analyzed from six registries from the Breast Cancer Surveillance Consortium (BCSC). Contributed data included demographic information, clinical findings, mammographic interpretation, and biopsy results. Measurements calculated were positive predictive values (PPVs) from screening mammography (PPV1), biopsy recommendation (PPV2), biopsy performed (PPV3), recall rate, cancer detection rate, mean cancer size, and cancer stage. Radiologist performance data are presented as 50th ( median), 10th, 25th, 75th, and 90th percentiles and as graphic presentations by using smoothed curves.Results: There were 2 580 151 screening mammographic studies from 1 117 390 women (age range, < 30 to >= 80 years). The respective means and ranges of performance outcomes for the middle 50% of radiologists were as follows: recall rate, 9.8% and 6.4% - 13.3%; PPV1, 4.8% and 3.4% - 6.2%; and PPV2, 24.6% and 18.8% - 32.0%. Mean cancer detection rate was 4.7 per 1000, and the mean size of invasive cancers was 13 mm. The range of performance outcomes for the middle 80% of radiologists also was presented.Conclusion: Community screening mammographic performance measurements of cancer outcomes for the majority of radiologists in the BCSC surpass performance recommendations. Recall rate for almost half of radiologists, however, is higher than the recommended rate.
