Patient-Assisted Compression in Screening Mammography: Patient Experience and Image Quality.

Abstract

Screening mammography is critical to reduce breast cancer mortality, yet many women cite pain from compression as a reason they avoid this test. We evaluated patient experience and image quality in screening patients opting for a handheld patient-assisted compression (PAC) device. After institutional review board approval, women screened between February and July 2018 with a synthetic 2D/tomosynthesis mammography unit were offered use of a handheld PAC device. Patient experience through survey, image quality, compression thickness, compression force, and average glandular dose were evaluated and compared between women opting for PAC and women opting for technologist-controlled compression (TC). Multivariable ordinal logistic and linear regression models were estimated to control for age and breast density. In addition, for women opting for PAC, image quality obtained with their current PAC mammogram was compared with that obtained with their prior TC mammogram, by using Wilcoxon/Pearson tests. Seventy-three percent of women preferred their mammogram experience with PAC compared with their prior mammogram without PAC. Women using PAC reported decreased anxiety compared with those using TC, after controlling for age and breast density (adjusted odds ratio [aOR] 0.22 [95% confidence interval (CI): 0.09-0.49]). There were no significant differences in image quality, compression thickness, or average glandular dose in exams for women using PAC compared with exams for women using TC. Women using PAC had significantly more compression force than women using TC had (P = 0.012). Mammography with PAC improves patient experience and results in similar image quality compared with mammography with TC.
