To better understand the barriers, motivators, and behaviors of women and healthcare professionals regarding the organized breast cancer screening program (DOCS), the National Cancer Institute (INCa) conducted a quantitative survey in 2010 involving 3,240 women and a series of qualitative interviews with 96 physicians. In each of the 44 radiology practices that participated in the survey, a questionnaire was offered to women coming in for a screening mammogram, regardless of the initial referral source—whether DOCS or individual screening (DI). The qualitative interviews were conducted with radiologists, gynecologists, and general practitioners. Among the women surveyed, advice from a healthcare professional was the most frequently cited factor (67%) encouraging screening. Furthermore, 55% of those who came for ID mistakenly believe they are part of the DOCS program. Although the DOCS program has a reputation for quality and simplicity, and aside from barriers specific to each specialty, the value placed on the second reading within the DOCS program does not seem sufficient to secure the full support of healthcare professionals. In conclusion, given the trust women place in healthcare providers, it is important to foster greater engagement among these professionals with the DOCS, especially since their support for this system is not yet universal.
