We aimed to investigate self-reported pain during screening with digital breast tomosynthesis (DBT).
The study was approved by the Regional Committee for Medical and Health Research Ethics in the South East of Norway (2015/424). Women completed a questionnaire about experienced pain directly after the examination, August-November 2019. A numeric rating scale (NRS, 0-10) was used. Data on compression force (N), pressure (kPa), and compressed breast thickness (mm) were obtained from the Digital Imaging and Communication in Medicine header and density assessment software. Stepwise ordinary least-squares regression was used to estimate mean self-reported pain score with 95% confidence interval (CI) for values of compression force, pressure, and compressed breast thickness.
The mean pain score was 1.9, whereof 19.3% (822/4266) of the women reported moderate or severe pain. The mean pain score of 2.6 (95% CI: 2.4-2.7) was observed at a compression force of 60 N, decreasing to 1.3 (95% CI: 1.2-1.4) at 130 N. The mean pain score of 1.3 (95% CI: 1.1-1.4) was at a compression pressure of 6 kPa, increasing to 2.9 (95% CI: 2.7-3.1) at 16 kPa. The mean pain score was 0.6 (95% CI: 0.4-0.6) at a compressed breast thickness of 20 mm, increasing to 2.9 (95% CI: 2.7-3.1) at 90 mm.
The mean pain score was low, 1.9 on NRS, for women screened with DBT. A compression force of 60-130 N and a pressure 6-16 kPa were associated with no or mild pain.
我们旨在调查在数字乳腺断层合成（DBT）筛查过程中自我报告的疼痛情况。
该研究获得了挪威东南部地区医疗卫生研究伦理委员会的批准（2015/424）。2019年8月至11月，女性在检查结束后立即填写了一份关于经历疼痛的问卷。采用数字评分量表（NRS，0 - 10）。从医学数字成像和通信头部及密度评估软件中获取压缩力（N）、压力（kPa）和压缩乳房厚度（mm）的数据。采用逐步普通最小二乘法回归来估计压缩力、压力和压缩乳房厚度值下自我报告疼痛评分的均值及95%置信区间（CI）。
平均疼痛评分为1.9，其中19.3%（822/4266）的女性报告有中度或重度疼痛。在压缩力为60 N时，平均疼痛评分为2.6（95% CI：2.4 - 2.7），在130 N时降至1.3（95% CI：1.2 - 1.4）。在压缩压力为6 kPa时，平均疼痛评分为1.3（95% CI：1.1 - 1.4），在16 kPa时升至2.9（95% CI：2.7 - 3.1）。在压缩乳房厚度为20 mm时，平均疼痛评分为0.6（95% CI：0.4 - 0.6），在90 mm时升至2.9（95% CI：2.7 - 3.1）。
接受DBT筛查的女性平均疼痛评分较低，NRS评分为1.9。60 - 130 N的压缩力和6 - 16 kPa的压力与无疼痛或轻度疼痛相关。
