The objective of this study was to assess trends in screening breast MRI utilization among privately insured women in the U.S. from 2007 to 2017.
The utilization of screening breast MRI among women aged 25-64 years from January 1, 2007, to December 31, 2017, was obtained using the MarketScan Commercial Database. We used Current Procedural Terminology codes to exclude breast MRI exams performed in women with a new breast cancer diagnosis and in women imaged to assess response to neoadjuvant therapy in the preceding 90 days. During the 11-year study, 351 763 study-eligible women underwent 488 852 MRI scans.
An overall 55.0% increase in screening breast MRI utilization was observed over the study period, with a steadily increasing trend. The greatest annual increase in percent utilization was from 2007 to 2008 at 16.6%. The highest utilization rate was in 2017, in which 0.4% of women aged 25-64 years underwent screening breast MRI. Of the women who underwent screening MRI with sufficient follow-up, 76.5% underwent only one examination during the study period.
Utilization of screening breast MRI has increased steadily in the past decade to a peak of 0.4% of adult women. However, an estimated 9% of U.S. women are eligible for high-risk breast MRI screening; thus, utilization falls short of optimal compliance. Further studies to evaluate the barriers to screening compliance may help optimize utilization.
本研究的目的是评估2007年至2017年美国参加私人保险的女性中乳腺MRI筛查的使用趋势。
利用MarketScan商业数据库获取2007年1月1日至2017年12月31日期间25至64岁女性的乳腺MRI筛查使用情况。我们使用现行程序术语代码排除在新诊断为乳腺癌的女性以及在过去90天内为评估新辅助治疗反应而进行成像的女性中进行的乳腺MRI检查。在为期11年的研究中，351763名符合研究条件的女性接受了488852次MRI扫描。
在研究期间，乳腺MRI筛查的使用总体增加了55.0%，且呈稳步上升趋势。使用率年度增长最大的是2007年至2008年，为16.6%。使用率最高的是2017年，其中25至64岁的女性中有0.4%接受了乳腺MRI筛查。在接受了充分随访的筛查MRI的女性中，76.5%在研究期间仅接受了一次检查。
在过去十年中，乳腺MRI筛查的使用率稳步上升，达到成年女性的0.4%的峰值。然而，估计有9%的美国女性符合高危乳腺MRI筛查的条件；因此，使用率未达到最佳依从性。进一步评估筛查依从性障碍的研究可能有助于优化使用率。
