Differences in utilization of screening mammography partly explain the increased breast cancer mortality observed in African American (AA) women compared with non-Hispanic White women. However, the contribution of noncompliance from women who do not come for their scheduled screening mammography appointment (ie, no-shows) is unknown. The purpose of this study was to investigate racial differences in no-show rates for screening mammography.
Women scheduled for routine screening mammograms between January 2018 and March 2018 were identified from the Joanne Knight Breast Health Center at Siteman Cancer Center in St. Louis, Missouri. Using a case-control design, this study retrospectively identified patients who no-showed for their mammograms (cases) and randomly sampled an equal number of patients who completed their mammograms (controls). These participants were compared by race. The main outcome measure was whether AA race was associated with no-shows for screening mammography.
During the study period, 5060 women were scheduled for screening mammography, and 316 (6.2%) did not keep their appointment (ie, they no-showed). Women who no-showed were more likely to be AA than women who kept their appointment (odds ratio, 2.64; 95% confidence interval, 1.90-3.67). Even after adjustments for marital status, insurance type, and place of residence, AA race was still significantly associated with no-shows for screening mammography.
This study identified a no-show rate of 6.2% for screening mammography at the authors' institution. Women who no-showed were more likely to be AA than women who completed their mammogram even after adjustments for multiple factors. These data can be leveraged for future studies aimed at improving mammography attendance rates among AA women.
利用筛查性乳房 X 光检查的差异部分解释了与非西班牙裔白人女性相比，非洲裔美国（AA）女性的乳腺癌死亡率上升的原因。然而，对于那些未按预约时间前来进行筛查性乳房 X 光检查的女性（即失约者）的不遵约情况的影响尚不清楚。本研究旨在调查筛查性乳房 X 光检查中种族差异导致的失约率。
从密苏里州圣路易斯市 Siteman 癌症中心的 Joanne Knight 乳腺健康中心确定了 2018 年 1 月至 2018 年 3 月期间预约进行常规筛查性乳房 X 光检查的女性。使用病例对照设计，本研究回顾性地确定了失约进行乳房 X 光检查的患者（病例），并随机抽取了相同数量的完成乳房 X 光检查的患者（对照）。对这些参与者按种族进行比较。主要结局指标是 AA 种族是否与筛查性乳房 X 光检查的失约有关。
在研究期间，有 5060 名女性预约了筛查性乳房 X 光检查，其中 316 人（6.2%）未如约进行检查（即失约）。失约者更有可能是 AA 女性而非如约进行检查的女性（比值比，2.64；95%置信区间，1.90-3.67）。即使在调整了婚姻状况、保险类型和居住地后，AA 种族与筛查性乳房 X 光检查的失约仍存在显著相关性。
本研究确定了作者所在机构筛查性乳房 X 光检查的失约率为 6.2%。即使在调整了多个因素后，失约者更有可能是 AA 女性而非完成乳房 X 光检查的女性。这些数据可用于未来旨在提高 AA 女性接受乳房 X 光检查比例的研究。
