Universidade Federal de GoiásTo analyze the access to mammographic screening of the Unified Health System (SUS), as well as a geographic distribution of the equipment in Brazil and its Health Regions, in 2016. Data on the number of mammographs available for SUS were collected of the National Register of Health Establishments (CNES / DATASUS). The equipment was geo-referenced according to its location, headquarters of the municipality and Region of Health. The distance of 60 km was considered as the maximum limit to be covered for the examination. A linear regression analysis was performed to evaluate the relationship between the distribution of women aged 50-69 years with a number of mammograms by the Health Region. In 2016, in Brazil, 2,113 mammographs were available for SUS, 6 % Installed in the North Macroregion, 28% in the Northeast, 39% in the Southeast, 18% in the South, and 8% in the Midwest. When analyzing the spatial coverage of up to 60 km of the mammography network, it was observed that 4,502 (80.9%) municipalities had mammograms available for the SUS and coverage was 93.8% of the target population. The linear regression showed a distribution of SUS equipment was adequate, and 438 Health Regions, 405 (92.5%) had mammography. A geospatial assessment showed that gaps (7.5%) were concentrated in the North and Midwest Macroregions, these being environmental preservation, indigenous lands and military areas. The linear regression coefficient, with value close to 1 (1.1271), showed excellent accuracy of the distribution. The regression dispersion of 0.6615 indicated that the distribution of mammographs to the existing population was accurate. This study allowed to infer that the geographic distribution of the equipment available for SUS is not a factor preventing the target population’s access to mammographic screening in Brazil.Brazilian Public Health System, Facility Access, mammography, mass screening.
