BACKGROUND: To evaluate the cost-effectiveness ratio and economic impact of the Rapid Antigen Test (TR-Ag) to replace RT-PCR for the detection of the new Coronavirus in the Unified Health System (SUS). METHODS: This is a cost-effectiveness analysis. Clinical protocols were used for the diagnosis of COVID-19 at the São José Municipal Hospital, located in the city of Itaberá-SP. The Incremental Cost-Effectiveness Ratio (ICER) was divided into two scenarios. In the first, the accuracy reported by the test manufacturers was included, and in the second, the cost resulting from a systematic review. Both were compared with the performance of the RT-PCR test. The increase in diagnoses was chosen as a health outcome and absenteeism was used as a criterion for assessing the economic impact. RESULTS: The analysis resulted in incremental cost-effectiveness ratios of R$ 42,136.67 and R$ 68,329.73 for every thousand tests, according to the accuracy of the manufacturers' TR-Ag tests and what is reported in the literature in relation to RT-PCR, respectively. The average value found for the RT-PCR test (R$ 202.87) represents an increase of 165.32% in cost in relation to the value found for the TR-Ag. 4,305 tests were performed between April 2020 and December 2021 at the referral hospital. Also, maintaining the use of RT-PCR as the first choice for diagnosing COVID-19 and regulating absenteeism in the economically active population could have an impact of up to R$ 1,022,779.68 on municipal management. CONCLUSION: It is concluded that the TR-Ag are configured as a cost-effective alternative for the SUS in the detection of the new Coronavirus. The strategy becomes economically favorable for the expansion of testing, combating the COVID-19 pandemic and reducing the impact on the local economy. However, studies are needed to validate the accuracy of the tests so that economic evaluations on the subject are more assertive.
OBJECTIVE: To analyze the factors associated with the proportion of abnormal results in screening mammograms. METHODS: Ecological study, with data from DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE, and Sistema e-Gestor, from 2016 to 2019, of women aged 50 to 69 years in the 645 municipalities of São Paulo (Brazil). Independent variables were associated with the outcome: proportion of unsatisfactory coverage of abnormal test results (Breast Imaging Reporting and Data System - BI-RADS® 0, 4 and 5 proportion >10% of tests performed). Multiple Poisson regression was used. RESULTS: Higher proportion of screening mammography (PR=1.20; 95%CI: 1.00;1.45), higher percentage of poor (PR=1.20; 95%CI: 1.07;1.36), low (PR=1.57; 95%CI: 1.38;1.78) and medium coverage of the Family Health Strategy (ESF) (PR=1.30; 95%CI: 1.09;1.52) were associated to the outcome. CONCLUSION: Socioeconomic and FHS coverage factors mediate the proportion of mammograms with abnormal results in public health services. Therefore, they are important aspects in the fight against breast cancer.

RESUMEN Objetivo: Analizar los factores asociados a la proporción de resultados alterados en las mamografías de tamizaje. Métodos: Estudio ecológico, con datos de DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE y Sistema e-Gestor, de 2016 a 2019, de mujeres de 50 a 69 años en los 645 municipios de São Paulo (Brasil). Las variables independientes se asociaron con el resultado: proporción de cobertura insatisfactoria de resultados de pruebas alteradas (BreastImagingReporting and Data System - BI-RADS® 0, 4 y 5 proporción >10% de pruebas realizadas). Se utilizó la regresión de Poisson múltiple. Resultados: Mayor proporción de mamografía de tamizaje (RP=1,20; IC95%: 1,00;1,45), mayor porcentaje de mala (RP=1,20; IC95%: 1,07;1,36), baja (RP=1,57; IC95%: 1,38) ;1,78) y cobertura media de la Estrategia Salud de la Familia (ESF) (RP=1,30; IC95%: 1,09;1,52) se asociaron al desenlace. Conclusión: Factores socioeconómicos y de cobertura de la ESF median la proporción de mamografías alteradas en el servicio público. Por lo tanto, son aspectos importantes en la lucha contra CM.
RESUMO Objetivo: Analisar os fatores associados aproporção de resultados alterados nas mamografias de rastreamento. Métodos: Estudo ecológico, com dados do DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE, e Sistema e-Gestor, de 2016 a 2019, de mulheres de 50 a 69 anos dos 645 municípios de São Paulo (Brasil).Variáveis independentes foram associadas ao desfecho: proporção de cobertura insatisfatória de resultados de exames alterados (proporção Breast Imaging Reporting and Data System - BI-RADS® 0, 4 e 5 >10% dos exames realizados). Utilizou-se regressão múltipla de Poisson. Resultados: Maior proporção de mamografia de rastreamento (RP=1,20; IC95%: 1,00;1,45), maior porcentagem de pobres (RP=1,20; IC95%: 1,07;1,36), baixa (RP= 1,57; IC95%: 1,38;1,78) e média cobertura de Estratégia Saúde da Família (ESF) (RP=1,30; IC95%: 1,09;1,52) foram associados ao desfecho. Conclusão: Fatores socioeconômicos e de cobertura da ESF medeiam a proporção de mamografias alteradas no serviço público. Portanto, são aspectos importantes no combate ao câncer de mama.
