Objectives: to assess the knowledge of health workers on radiological screening for breast cancer.
Methods: Descriptive cross-sectional study, carried out from February 18 to April 5, 2019. Inclusion criteria: general practitioners, doctors specializing in gynecology (DES), gynecologists, midwives / midwives from three university hospital centers in the city of Ouagadougou. Two hundred and two health workers were selected.
Results: 143 health workers or 70.79% prescribed breast imaging. Female staff represented 72.03%, or a sex ratio of 0.39. The average age of prescribers was 38.17 + 7.20 years. 20.98% of agents regularly ordered breast imaging with a weekly mean of 2.67 + 2.04. The best known x-rays were mammography in 94.40% of cases and
breast ultrasound in 90.21% of cases. As a means of screening for breast cancer, 48.95% of prescribers cited mammography and 36.36%, breast ultrasound. Regarding the age at the start of screening, 58.73% of prescribers were in favor of starting it before the age of 40, with a periodicity of 2 years for 30.07% of them. The American
College of Radiology (ACR) Breast Imaging Report and Data System (BIRADS) classification was known by 37.76% of prescribers. The mean knowledge score of prescribers was 46.57 + 16.45%.
Conclusion: There are gaps in the knowledge of prescribers in terms of radiological screening for breast cancer in Burkina Faso. Emphasis should be placed on training these agents, a factor in the success of a systematic breast cancer screening program in Burkina Faso.
