文献中缺乏对从筛查乳腺X线摄影到诊断性成像再到乳腺穿刺活检术所预计时间的明确基准。本研究使用2005年至2019年提交至全国乳腺中心质量指标（NQMBC）的总体数据对诊断性成像工作的时效性进行了评估。共有419个乳腺中心提交了180,515例患者的筛查乳腺X线摄影至诊断性成像的时间数据。整体时间为7天，75百分位数、25百分位数和10百分位数分别为5、10和13.5天。研究期间，工作日平均时间从9.1天降至7.1天（p < 0.001），在表现最差的四分之一中改善最为显著。筛查中心和中西部地区的中心的诊断性成像时间显著较短。共有406个设施提交了386,077名患者的诊断性成像至乳腺穿刺活检术的时间数据。平均时间为6个工作日，75百分位数、25百分位数和10百分位数分别为4、9和13.7天。从平均9.0天降至6.3天（p < 0.001），在表现最差的四分之一中改善最为显著。筛查中心、中西部地区和都市地区的中心的活检术时间显著较短。在强大的数据集中，从筛查乳腺X线摄影至诊断性成像以及从诊断性成像至活检术的时间从2005年至2019年有所降低。平均而言，患者可以期待在异常结果出现后的1周内进行诊断性成像和活检。监测并与报告的数据进行比较可能提高乳腺护理的质量。©2023. 作者。

The literature lacks well-established benchmarks for expected time between screening mammogram to diagnostic imaging and then to core needle breast biopsy.Timeliness of diagnostic imaging workup was evaluated using aggregate data from 2005 to 2019 submitted to The National Quality Measures for Breast Centers (NQMBC).A total of 419 breast centers submitted data for 1,805,515 patients on the time from screening mammogram to diagnostic imaging. The overall time was 7 days with 75th, 25th, and 10th percentile values of 5, 10, and 13.5 days, respectively. The average time in business days decreased from 9.1 to 7.1 days (p < 0.001) over the study period with the greatest gains in poorest-performing quartiles. Screening centers and centers in the Midwest had significantly shorter time to diagnostic imaging. Time from diagnostic imaging to core needle biopsy was submitted by 406 facilities representing 386,077 patients. The average time was 6 business days, with 75th, 25th, and 10th percentiles of 4, 9, and 13.7 days, respectively. Time to biopsy improved from a mean of 9.0 to 6.3 days (p < 0.001) with the most improvement in the poorest-performing quartiles. Screening centers, centers in the Midwest, and centers in metropolitan areas had significantly shorter time to biopsy.In a robust dataset, the time from screening mammogram to diagnostic imaging and from diagnostic imaging to biopsy decreased from 2005 to 2019. On average, patients could expect to have diagnostic imaging and biopsies within 1 week of abnormal results. Monitoring and comparing performance with reported data may improve quality in breast care.© 2023. The Author(s).
