Organised breast cancer screening: the acceptability of a French decision-aid tool among women and Health professionals

Background: The decision decision-aid (lamammo lamammo-etvous.fr) was designed to support women s decision on whether or not to take part in organised breast cancer screening (DOCS) via mammography.Objectives: To assess its acceptability among women and healthcare professionals. The secondary objective was to assess its impact on women s knowledge, decision decision-making conflict and intention to participate in DOCS.Method: A cross cross-sectional survey involving a beta test of the DA, conducted in France in 2023 at three health centres. Healthcare professionals (general practitioners, midwives and gynecologists) were involved. Women were invited to take part whilst waiting in the consultation room. The questionnaire for healthcare professionals assessed the acceptability and real real-world use of the DA. The questionnaire for women assessed acceptability, level of knowledge, decision conflict (DCS DCS-10) and intention to participate in the DOCS before and after readingthe DA.Results: 18 healthcare professionals and 55 women completed the questionnaires. Acceptability was good among both women and healthcare professionals. The tool was considered useful (66.7% of healthcare professionals and 77.6% of women), clear and relevant. Reading the DA significantly increased the women s level of knowledge (10.15 vs 12.18; p < 0.001), reduced decision decision-making conflict (20.19 vs 31.70; p < 0.001), and did not alter their motivation to participate in the DOCS (9.46 vs 9.41; p = 0.742). The evaluation revealed differences in perception between women and healthcare professionals: 50% of healthcare professionals consideredthe text too long, compared with only 10.2% of women ( p < 0.001). The information was perceived as biased against the DOCS by 38.9% of healthcare professionals, compared with 2.0% of women (p < 0.001).Conclusion: This acceptability study found that reading this DA, which was well well-received by healthcare professionals and women alike, significantly increased women s level of knowledge, reduced decision decision-making conflict, and did not alter their motivation to participate in the DOCS. These findings will need to be confirmed by larger larger scale studies.
