目的测量COVID-19大流行和相关指南对乳房X线检查的影响程度。数据来源独立蓝十字为接受乳房X线检查的妇女提供了来自医疗索赔和资格文件的去识别汇总数据。研究设计我们使用了不同的差异的方法来表征随着时间的推移进行的乳房X光检查的变化，以及估计清除错过的乳房X光检查队列的时间的计算公式。在2020年3月11日之后的20周内，筛查性乳房X光检查和诊断性乳房X光检查的数量平均下降了预期水平的58%和38%。在第15周（4月8日至14日）观察到最低量，当时筛查和诊断性乳房X光检查分别下降了99%和74%。乳腺癌在第19周（5月）开始反弹，诊断性乳房X光检查达到与前几年相似的水平，筛查性乳房X光检查仍低于预期14%。我们估计，在我们的研究样本中，至少需要22周才能清除错过的乳房X光检查队列。结论由于COVID-19大流行，乳房X光检查的提供受到了严重干扰。
Objective To measure the extent to which the provision of mammograms was impacted by the COVID-19 pandemic and surrounding guidelines.Data Sources De-identified summary data derived from medical claims and eligibility files were provided by Independence Blue Cross for women receiving mammograms.Study Design We used a difference-in-differences approach to characterize the change in mammograms performed over time and a queueing formula to estimate the time to clear the queue of missed mammograms.Data Collection We used data from the first 30 weeks of each year from 2018 to 2020.Principal Findings Over the 20 weeks following March 11, 2020, the volume of screening mammograms and diagnostic mammograms fell by 58% and 38% of expected levels, on average. Lowest volumes were observed in week 15 (April 8 to 14), when screening and diagnostic mammograms fell by 99% and 74%, respectively. Volumes began to rebound in week 19 (May), with diagnostic mammograms reaching levels to similar to previous years' and screening mammograms remaining 14% below expectations. We estimate it will take a minimum of 22 weeks to clear the queue of missed mammograms in our study sample.Conclusions The provision of mammograms has been significantly disrupted due to the COVID-19 pandemic.
