Clinical quality assurance in breast cancer screening and diagnosis: a warning regarding mammographic positioning

This study aimed to evaluate the clinical image quality of mammograms performed in users of the Brazilian Unified Health System (SUS) referred to a tertiary hospital. Methods: A prospective study assessed mammograms from women referred to a specialist breast center in Goiânia, Goiás, Brazil, between May and October 2017. Scans performed in the preceding 6 months, either screening or diagnostic, were included in the study. Clinical quality was determined from 40 variables related to patient identification, technical performance, the equipment, radiological findings, reporting of results, and breast positioning. Scans performed in the public and private healthcare networks were compared regarding mammographic positioning. Results: Overall, 4,560 variables associated with the clinical quality of the images were evaluated in scans from 114 women with a mean age of 50.6 years. A total of 660 (14.47%) inadequacies were found, 443 (67.12%) of which were related to breast positioning. The most common errors were as follows: pectoral muscle could not be seen in 86.8% of scans in the craniocaudal view and inframammary angle could not be seen in 79.8% of scans in the mediolateral oblique view. Considering the breast-positioning criteria evaluated in the mediolateral oblique view, there was a greater risk of the breast not being centrally positioned with the nipple in profile (RR 4.66; 95%CI 1.05−20.62; p=0.02) and of nonvisualization of the retro-areolar area (RR 4.14; 95%CI 0.92−18.66; p=0.04) in the exams performed in the private compared to the public network.

Opportunistic mammography screening by the Brazilian Unified Health System in 2019

Introduction: Mammography screening has been the best method for detecting early tumors and reducing breast cancer mortality according to different studies. In Brazil, the number of women who undergo mammography tests by the Brazilian Unified Health System (SUS) has been far below international recommendations. Objective: To describe the number of mammographies, mammography coverage, and the amount spent on this exam during 2019 by SUS, in Brazil. Method: Ecological study with data from the Department of Informatics of the Brazilian Unified Health System and the Brazilian Institute for Geography and Statistics in order to verify the number of mammographies performed by the SUS concerning the Brazilian female population in Brazil, in the age group of 50 to 69 years, in the states and in macro-regions during 2019. Results: In 2019, 2,660,469 mammographies were performed in the country out of the expected total of 12,154,979, accounting for a 21.9% mammography coverage by SUS at the cost of BRL 117,841,231.97. The lowest coverage rates were verified in the states of Amapá (0.6%) and the Federal District (4.9%), whereas the best rates were found in the states of Paraná (29.7%) and Alagoas (29.6%). Conclusions: The number of mammographies performed in Brazil in 2019 by SUS corresponded to almost » of the country's need, with mammography coverage far below the target and being widely different among the many Brazilian states.

Análise retrospectiva do trânsito do delgado em um serviço de radiologia de hospital geral / Retrospective analysis of small bowel contrast examinations at the radiology service of a general hospital

OBJETIVO: Os autores se propõem a revisar os exames de trânsito do delgado, a fim de demonstrar os principais diagnósticos e achados radiológicos, e o atual benefício para o paciente. MATERIAIS E MÉTODOS: Estudo retrospectivo e descritivo realizado a partir de levantamento de exames realizados no período de janeiro/2001 a junho/2002, no serviço de radiologia do Hospital Santa Cruz da Beneficência Portuguesa de Niterói. RESULTADOS: Do total de 60 exames, 24 (40,0 por cento) apresentaram alterações radiológicas (anatômicas, enterites, divertículos, relacionadas a cirurgias e outras) e 36 (60,0 por cento) foram normais. Observamos que 36 pacientes (60,0 por cento) tinham entre 35 e 65 anos incompletos, apenas dois (3,32 por cento) eram menores de 18 anos e o paciente mais idoso tinha 87 anos. CONCLUSÃO: Apesar do advento da endoscopia para a avaliação do trato gastrintestinal superior e inferior, o uso do estudo contrastado do intestino delgado se manteve como método de escolha para avaliação do duodeno, jejuno e íleo. Sabe-se que o trânsito do delgado é a principal técnica diagnóstica para o estudo deste órgão e importante para o estudo das enterites, além de ser um exame de fácil execução e de alta sensibilidade. Dessa forma, estamos reforçando a sua importância diagnóstica e devemos ter em mente que o exame do trato gastrintestinal superior é complementar, devendo considerar suas limitações e vantagens.
