Estimated Loss of Productivity Attributed to Cardiovascular Diseases in South America. / Estimativa de Produtividade Perdida Atribuída a Doenças Cardiovasculares na América do Sul.

BACKGROUND: Cardiovascular diseases (CVD) have significant health and economic burdens. In South America, the loss of productivity related to these diseases has not yet been well explored. OBJECTIVE: Estimate the potentially productive years of life lost (PPYLL) and loss of productivity related to premature mortality associated with CVD in South America, in 2019. METHODS: Mortality data available from the 2019 Global Burden of Disease Study were used to estimate the burden of disease attributable to CVD. For monetary calculations of productivity loss, a proxy of the human capital approach was used. Data were stratified by sex, in working age groups. RESULTS: The total number of deaths due to CVD in South America in 2019 was 754,324, and the total number of PPYLL was 2,040,973. The total permanent loss of productivity was approximately US$ 3.7 billion and US$ 7.8 billion in purchasing power parity, equivalent to 0.11% of the gross domestic product. The cost per death was US$ 22,904, and the ratio between men and women for the cost per death was 1.45. The variation in scenarios indicates that the estimates are robust, even with important differences between countries. CONCLUSIONS: CVD impose a significant economic burden on countries in South America. The characterization of this burden can support governments in the allocation of resources for the planning and execution of health policies and interventions in promotion, prevention, and recovery.

FUNDAMENTO: As doenças cardiovasculares (DCV) têm ônus sanitário e econômico significativos. Na América do Sul (AS), a perda de produtividade relacionada a estas enfermidades ainda não foi bem explorada. OBJETIVO: Estimar os anos de vida produtiva perdidos (AVPP) e a perda de produtividade relacionados a mortalidade prematura associada as DCV na AS, em 2019. MÉTODOS: Empregou-se dados de mortalidade disponíveis no Global Burden of Disease Study 2019 na estimativa da carga de doença atribuível a DCV. Para os cálculos monetários da perda da produtividade usou-se uma proxy da abordagem de capital humano. Estratificou-se por sexo, nas faixas etárias de trabalho. RESULTADOS: O número total de mortes por DCV na AS no ano de 2019 foi de 754.324 e os AVPP foram 2.040.973. A perda permanente de produtividade total foi de aproximadamente US$ 3,7 bilhões e US$ 7,8 bilhões em paridade do poder de compra, equivalente a 0,11% do produto interno bruto. O custo por morte foi de US$ 22.904, e a razão desse custo por óbito, entre homens e mulheres foi 1,45. A variação dos cenários aponta robustez nas estimativas, mesmo com diferenças importantes entre os países. CONCLUSÕES: As DCV impõem um ônus econômico significativo a este bloco de países. A caracterização deste fardo pode amparar os governos na alocação de recursos destinados ao planejamento e execução de políticas e intervenções sanitárias, sejam de promoção, prevenção ou recuperação.

Health and economic burden of sugar-sweetened beverages consumption in Brazil.

Sugar-sweetened beverages (SSBs) are a major source of added sugar and are associated with noncommunicable diseases (NCDs) such as obesity and diabetes. This study assessed the impact of SSBs consumption on disease burden in Brazil, including deaths, disability-adjusted life years (DALYs), and healthcare costs. A 3-stage methodology was used to assess the direct effects of SSBs on diabetes, cardiovascular diseases, and body mass index (BMI), along with the influence of BMI on disease incidence. These assessments were then used to estimate the economic and health burden using population-attributable factors. Results showed that 2.7% and 11% of adult and children overweight/obesity cases were attributable to SSBs, respectively. SSBs consumption in Brazil led to 1,814,486 cases, 12,942 deaths, 362,088 DALYs, and USD 2,915.91 million in medical costs related to diabetes, cardiovascular diseases, oncological diseases, and other NCDs. Urgent implementation of public policies is crucial to address the consumption of SSBs, recognized as a key risk factor for NCDs.

Cost-effectiveness analysis and budgetary impact of anidulafungin treatment for patients with candidemia and other forms of invasive candidiasis in Brazil.

Candidemia and other forms of invasive candidiasis (C/IC) are serious conditions, especially for immunosuppressed individuals with prolonged hospitalization in intensive care units (ICU). This study analyzed the incremental cost-effectiveness and budgetary impact (BI) of treatment for IC with anidulafungin compared to amphotericin B lipid complex (ABLC) and amphotericin B deoxycholate (ABD) or conventional amphotericin B (CAB), in the Brazilian Unified Health System (SUS). A decision model was conducted with a time horizon of two weeks from the perspective of SUS. The primary effectiveness endpoints were survival and treatment response rate. All patients were followed up until successful therapy or death. BI analysis was performed based on the measured demand method. A five-year time horizon was adopted based on the number of hospitalizations (per 1,000 hospitalizations). For effectiveness measured in the successful response rate (SRR), anidulafungin dominated the ABLC and ABD formulations. In the results of the analysis with the effectiveness measured according to survival, anidulafungin had a better cost-effectiveness ratio (R$988.26/survival) compared to ABD (R$16,359.50/survival). The BI estimate related to the incorporation of anidulafungin suggests savings of approximately 148 million reais in 5 years when comparing it to ABD. The economic evaluation of anidulafungin and its comparators found it to be cost-effective. The consensus of international scientific societies recommends it as a first-line drug for IC, and its incorporation by SUS would be important.

Using the analytic hierarchy process to elicit patient preference in the evaluation of first-line treatment of HER2-overexpressing metastatic breast cancer / Uso do processo analítico hierárquico para eleger a preferência do paciente na avaliação da primeira linha de tratamento do câncer de mama metastático her2 hiperexpresso

Abstract Background The many combinations of chemotherapeutic agents and biologicals available in the Brazilian National Health System for the treatment of metastatic breast cancer require analysis that contribute to decision making. Objective The study's primary aim was to evaluate the first-line treatment of HER2- overexpressing metastatic breast cancer from the Brazilian Unified Health System perspective using multicriteria decision analysis (MCDA). Method The treatment options evaluated were (a) pertuzumab combined with trastuzumab and docetaxel, and (b) trastuzumab in combination with docetaxel. Using the hierarchical analytical method, medical oncologists compared the relevance of five predefined criteria: overall survival, response to treatment, adverse events, cost- effectiveness, and budget impact. Results The therapeutic scheme considered more appropriate by the model was pertuzumab combined with trastuzumab and docetaxel. The most sensitive criteria were adverse events, cost-effectiveness, and budget impact. The results suggest that the classification has a close relationship with the perspective of healthcare professionals participating in the questionnaire. Conclusion Defining the treatment of an incurable disease associated with a short survival time and high-cost treatment options necessitates complex decision-making. MCDA allows the weighting of criteria and considering criteria that would be difficult to measure in other methods, such as cost-effectiveness. These aspects differ from economic models and contribute to a broader evaluation of health decision-making.

Resumo Introdução As diversas combinações de agentes quimioterápicos e biológicos disponíveis no Sistema Único de Saúde brasileiro para o tratamento do câncer de mama metastático requerem análises que contribuam para a tomada de decisões. Objetivo O objetivo principal deste estudo foi avaliar o tratamento de primeira linha para câncer de mama metastático HER2 hiperexpresso sob a perspectiva do Sistema Único de Saúde, utilizando a análise de decisão multicritérios (MCDA). Método As opções de tratamento avaliadas foram: (a) pertuzumabe em combinação com trastuzumabe e docetaxel, e (b) trastuzumabe em combinação com docetaxel. Usando o método analítico hierárquico, médicos oncologistas compararam a relevância dos cinco critérios predefinidos: sobrevida global, resposta ao tratamento, eventos adversos, custo-efetividade e impacto orçamentário. Resultados O esquema terapêutico considerado mais apropriado pelo modelo foi pertuzumabe em combinação com trastuzumabe e docetaxel. Os critérios mais sensíveis foram eventos adversos, custo-efetividade e impacto orçamentário. Os resultados sugerem que a classificação está associada à perspectiva do profissional de saúde participante do questionário. Conclusão Definir o tratamento de uma doença incurável associada a um tempo de sobrevida curto e opções de tratamento de alto custo requer uma tomada de decisão complexa. O MCDA permite ponderar e considerar critérios que seriam difíceis de medir em outros modelos de decisão. Esses aspectos contribuem para uma avaliação mais ampla da tomada de decisões em saúde.

Cost-effectiveness analysis and budgetary impact of anidulafungin treatment for patients with candidemia and other forms of invasive candidiasis in Brazil

ABSTRACT Candidemia and other forms of invasive candidiasis (C/IC) are serious conditions, especially for immunosuppressed individuals with prolonged hospitalization in intensive care units (ICU). This study analyzed the incremental cost-effectiveness and budgetary impact (BI) of treatment for IC with anidulafungin compared to amphotericin B lipid complex (ABLC) and amphotericin B deoxycholate (ABD) or conventional amphotericin B (CAB), in the Brazilian Unified Health System (SUS). A decision model was conducted with a time horizon of two weeks from the perspective of SUS. The primary effectiveness endpoints were survival and treatment response rate. All patients were followed up until successful therapy or death. BI analysis was performed based on the measured demand method. A five-year time horizon was adopted based on the number of hospitalizations (per 1,000 hospitalizations). For effectiveness measured in the successful response rate (SRR), anidulafungin dominated the ABLC and ABD formulations. In the results of the analysis with the effectiveness measured according to survival, anidulafungin had a better cost-effectiveness ratio (R$988.26/survival) compared to ABD (R$16,359.50/survival). The BI estimate related to the incorporation of anidulafungin suggests savings of approximately 148 million reais in 5 years when comparing it to ABD.

Cost-Effectiveness Analysis of the Implementation of Cryptococcal Antigen Lateral Flow Assay for the Diagnosis of Cryptococcal Meningitis in Symptomatic People Living With Human Immunodeficiency Virus in Brazil.

OBJECTIVES: Cryptococcal meningitis constitutes a significant source of mortality in the developing world. Annually, approximately 625 000 deaths occur worldwide among patients with human immunodeficiency virus (HIV) infection. This study aims to assess the cost-effectiveness of implementing cryptococcal antigen lateral flow assay (CRAG-LFA) screening in Brazil compared with the current practice. METHODS: An economic evaluation using a Monte Carlo microsimulation was conducted, considering the perspective of the Brazilian Public Health System, to calculate the cost-effectiveness of 4 diagnosis tests: (1) CRAG-LFA, (2) the cryptococcal antigen latex agglutination (CRAG-LA) test, (3) India ink, and (4) nontracking as a baseline. The time horizon comprised 1 year for the intervention and 5 years for the budgetary impact analysis. Two primary effectiveness outcomes were considered: years of life and quality-adjusted life-years. RESULTS: CRAG-LFA has extended dominance vis à vis CRAG-LA and India ink. CRAG-LFA would cost $418.46 more than CRAG-LA for the treatment of each symptomatic patient living with HIV, with an incremental cost effectiveness ratio of $2478.75/quality-adjusted life year. The budgetary impact analysis estimated that the incorporation of CRAG-LFA would have an additional cost of $1 959 236.50 in 5 years. CONCLUSIONS: These findings suggest that, for patients living with HIV in the Brazilian Public Health System, the adoption of CRAG-LFA screening is cost-effective compared with the use of CRAG-LA and India ink. It represents an opportunity to prevent cryptococcal meningitis and its mortality in Brazil.

Cost-effectiveness analysis and budgetary impact of the Cryptococcal Antigen Lateral Flow Assay (CRAG-LFA) implementation for the screening and diagnosis of cryptococcosis in asymptomatic people living with HIV in Brazil.

Cryptococcal infection is a frequent cause of mortality in Brazilian HIV-infected patients. The present study aimed to evaluate the cost-effectiveness and budgetary impact of four cryptococcosis screening strategies in HIV-infected patients with CD4+ ≤ 200 cells/mm3, in Brazil. A Monte Carlo microsimulation was used to compare the following diagnostic tests: a systematic serum cryptococcal antigen (CRAG) screening with latex agglutination (CRAG-LA), a lateral flow immunochromatographic test (CRAG-LFA), India ink staining and no intervention. The rationale was that of the Unified Health System (SUS), and the time horizon was of one year for the intervention and of five years for the budgetary impact analysis (BIA). The effectiveness outcomes were years of life and years of life adjusted for quality (QALY). The cost-effectiveness analysis showed that the two cryptococcal antigen tests were cost-effective, presenting with superior results in comparison with India ink and no screening. CRAG-LFA, compared to CRAG-LA, has an incremental cost of US$0.25 and an incremental cost-effectiveness ratio of US$73.36 (considering the US dollar equal to 5 reais, the Brazilian current money). The probabilistic sensitivity analysis between CRAG-LFA and CRAG-LA, despite showing a high agreement between the two tests, indicated the superiority of CRAG-LFA. The BIA estimated that the incorporation of CRAG-LFA would have an additional cost of approximately U$S 10.4 million dollars in five years. These findings suggest that, for the group of studied patients, the adoption of CRAG-LFA and CRAG-LA are cost-effective, while the India ink test and no intervention are less effective strategies. The BIA showed that using the CRAG-LFA test for people living with HIV (PLHIV) with CD4+ ≤ 200 cells/mm3 could reduce costs for the Brazilian Unified Health System (SUS).

Drug prices in Latin American countries: the case of rheumatoid arthritis Biosimilars

Abstract Background: The objective of this paper is to analyze the prices of biological drugs in the treatment of Rheumatoid Arthritis (RA) in three Latin American countries (Brazil, Colombia and Mexico), as well as in Spain and the United States of America (US), from the point of market entry of biosimilars. Methods: We analyzed products authorized for commercialization in the last 20 years, in Brazil, Colombia, and Mexico, comparing them to the United States of America (USA) and Spain. For this analysis, we sought the prices and registries of drugs marketed between 1999 and October 1, 2019, in the regulatory agencies' databases. The pricing between countries was based on purchasing power parity (PPP). Results: The US authorized the commercialization of 13 distinct biologicals and four biosimilars in the period. Spain and Brazil marketed 14 biopharmaceuticals for RA, ten original, four biosimilars. Colombia and Mexico have authorized three biosimilars in addition to the ten biological ones. For biological drug prices, the US is the most expensive country. Spain's price behavior seems intermediate when compared to the three LA countries. Brazil has the highest LA prices, followed by Mexico and Colombia, which has the lowest prices. Spain has the lowest values in PPP, compared to LA countries, while the US has the highest prices. Conclusions: The economic effort that LA countries make to access these medicines is much higher than the US and Spain. The use of the PPP ensured a better understanding of the actual access to these inputs in the countries analyzed.(AU)

Cost-effectiveness analysis and budgetary impact of antipsychotics available in the Brazilian Unified Health System / Análise de custo-efetividade e impacto orçamentário dos antipsicóticos disponíveis no Sistema Único de Saúde brasileiro

Objective: To carry out a cost-effectiveness and budget impact analysis of antipsychotic use in adults to treat schizophrenia from the perspective of the Unified Health System (SUS). Methods: A Markov model simulated the treatment of schizophrenic patients with an initial average age of 25 years and a lifetime horizon. The possibility of combining drugs resulted in 20 pharmacotherapeutic strategies. Results: The lowest-cost strategy, risperidone/olanzapine, obtained values of $45,092.77 with effectiveness of 15.97 QALY. The incremental cost-effectiveness ratio in dollars/QALY of olanzapine/risperidone was 2,470.24, and risperidone/ziprasidone was 352,671.90, compared to the first option. All other therapeutic combinations were dominated. The budgetary impact assessment indicated that the most cost-effective choice could generate savings of US$ 1,555.00 on average, per patient, over five years. Conclusion: The therapeutic proposal with the lowest cost per patient was risperidone combined with olanzapine, revealing these two drugs as a strategy with lower budgetary impact and better cost-effectiveness.

Objetivo: Realizar uma análise de custo-efetividade e impacto orçamentário do uso de antipsicóticos em adultos para o tratamento da esquizofrenia, na perspectiva do Sistema Único de Saúde (SUS). Métodos: Um modelo de Markov simulou o tratamento de pacientes com esquizofrenia, com idade média inicial de 25 anos e horizonte lifetime. Analisaram-se 20 estratégias farmacoterapêuticas. Resultados: A estratégia de menor custo ­ risperidona/olanzapina ­ obteve valores de US$ 45.092,77, eficácia de 15,97 QALY. A relação custo-efetividade incremental em dólares/QALY da olanzapina/risperidona foi de 2.470,24, e de 352.671,90 para risperidona/ziprasidona, em comparação com a primeira opção. Todas as outras combinações terapêuticas foram dominadas. A avaliação do impacto orçamentário indicou que a escolha mais econômica geraria economia de US$ 1.555,00 em média, por paciente, ao longo de cinco anos. Conclusão: A proposta terapêutica de menor custo por paciente foi a risperidona associada à olanzapina, estratégia de menor impacto orçamentário e melhor custo-efetividade.

PEG-asparaginase and native Escherichia coli L-asparaginase in acute lymphoblastic leukemia in children and adolescents: a systematic review

Abstract Introduction Acute lymphoblastic leukemia (ALL) is the cancer with the highest incidence in childhood and adolescence, and pharmacotherapy is the primary form of treatment. Objective and methods A systematic review of the efficacy and safety of polyethylene glycol (PEG)-asparaginase in acute lymphoblastic leukemia therapy in children and adolescents was conducted to compare it with native Escherichia coli L-asparaginase. PubMed, Web of Science, Science Direct, Cochrane Library, Scopus, LILACS (Latin American and Caribbean Health Sciences Literature) and EMBASE databases were selected. The following outcomes were analyzed: complete remission of the disease, event-free survival, overall survival, anti-asparaginase antibody level, hypersensitivity reactions, asparaginase and asparagine serum levels, number of postdiagnosis events, and overall mortality. Five randomized controlled trials were included. Analysis of the quality of evidence and risk of bias was performed using the Cochrane recommendation tool and the GRADE system. Results The assessment results suggest that the level of certainty on the technology addressed is relatively weak from a methodological point of view. Evidence is insufficient to assess the effects on health outcomes because of the limited number and power of studies and important flaws in their design or conduct in classifying PEG-asparaginase as a superior drug or not, in the pharmacotherapy of ALL in children and adolescents. PEG-asparaginase can be used as a substitute for native E. coli L-asparaginase, demonstrating similar efficacy and safety. Conclusion The study may help decision-makers in the public health system to offer a more in-depth judgment on the therapeutic alternatives used to treat this neoplasm in children and adolescents.

[Economic assessment of dexrazoxane in prophylaxis of cardiotoxicity in children undergoing chemotherapy with anthracyclines]. / Avaliação econômica do uso de dexrazoxano na profilaxia de cardiotoxicidade em crianças em tratamento quimioterápico com antraciclinas.

Cancer in individuals 0 to 19 years of age is considered rare when compared to incidence in older age brackets, and is estimated at 2% to 3% of all malignant tumors recorded in Brazil. The use of anthracyclines is frequently associated with cardiotoxicity, and these drugs are part of approximately 60% of treatment protocols in pediatric oncology. Among the existing strategies for the prevention of cardiotoxicity, dexrazoxane obtained favorable results based on intermediate outcomes (biochemical markers and echocardiographic parameters). This study was based on a cost-effectiveness assessment comparing the use of dexrazoxane in different populations, besides an assessment of the budget impact from the technology's potential incorporation. The patient's lifetime was used as the timeline, and the analysis was performed from the perspective of the Brazilian Unified National Health System (SUS). A budget impact analysis was also performed for each technology. After a literature search, a Markov model was developed, capable of comparing the use of dexrazoxane in six profiles of patients at risk of developing cardiotoxicity. Use of the drug in children under 5 years of age proved to be the most cost-effective alternative (incremental cost effectiveness ratio - ICER of BRL 6,156.96), followed by use in all patients (ICER of BRL 58,968.70). If the price decreased to less than BRL 250.00 per vial, the alternative of using the drug in all children would become the most cost-effective. The budget impact at 5 years was BRL 30,622,404.81 for use only in children under 5 years of age. Using the technology in all the children could produce an incremental impact of BRL 94,352,898.77.

O câncer em indivíduos de 0 a 19 anos é considerado raro, quando comparado à incidência em faixas etárias maiores, sendo estimado entre 2% e 3% de todos os tumores malignos registrados no Brasil. O uso de antraciclinas está frequentemente associado ao aparecimento de cardiotoxicidade e faz parte de aproximadamente 60% dos protocolos terapêuticos em oncologia pediátrica. Dentre as estratégias existentes para a prevenção de cardiotoxicidade, o dexrazoxano obteve resultados favoráveis pautados em desfechos intermediários (marcadores bioquímicos e medidas ecocardiográficas). Foi desenvolvida, neste trabalho, uma avaliação de custo-efetividade que compare o uso do dexrazoxano em diferentes populações, além de uma avaliação do impacto orçamentário causado pela possível incorporação da tecnologia. Foi utilizado o horizonte temporal de toda a vida do paciente e a perspectiva de análise do Sistema Único de Saúde. Uma análise de impacto orçamentário para cada tecnologia também foi construída. Após uma busca na literatura, foi desenvolvido um modelo de Markov capaz de comparar o uso do dexrazoxano em seis perfis de pacientes com risco de desenvolver cardiotoxicidade. Usar o medicamento nas crianças menores de cinco anos de idade se mostrou a alternativa mais custo-efetiva (razão de custo-efetividade incremental - RCEI de R$ 6.156,96), seguida de usar em todos os pacientes (RCEI de R$ 58.968,70). Caso o preço diminua a um valor menor que R$ 250,00 por frasco, a alternativa de usar em todas as crianças se torna a mais custo-efetiva. O impacto orçamentário ao final de cinco anos foi de R$ 30.622.404,81 para uso apenas nas crianças menores de cinco anos. Usar a tecnologia em todas as crianças produziria um impacto incremental de R$ 94.352.898,77.

El cáncer en individuos de 0 a 19 años está considerado raro, cuando se compara la incidencia en franjas etarias mayores, estimándose entre 2% y 3% de todos los tumores malignos registrados en Brasil. El uso antraciclinas está frecuentemente asociado a la aparición de cardiotoxicidad y forma parte de aproximadamente un 60% de los protocolos terapéuticos en oncología pediátrica. Entre las estrategias existentes para la prevención de cardiotoxicidad, el dexrazoxano obtuvo resultados favorables pautados en desenlaces intermedios (marcadores bioquímicos y medidas ecocardiográficas). Se desarrolló en este trabajo, una evaluación de costo efectividad que compare el uso del dexrazoxano en diferentes poblaciones, además de una evaluación del impacto presupuestario causado por la posible incorporación de la tecnología.

En caso de que el precio disminuya a un valor inferior a BRL 250,00 por frasco, la alternativa de usarlo en todos los niños se convierte en la más costo-efectiva. El impacto presupuestario tras 5 años fue de BRL 30.622.404,81 para su uso exclusivo en niños menores de 5 años. Usar esta tecnología en todos los niños, tendría un impacto presupuestario incrementándolo hasta los BRL 94.352.898,77.

Cost-Effectiveness of Proton Versus Photon Therapy in Pediatric Medulloblastoma Treatment: A Patient Volume-Based Analysis.

BACKGROUND: Proton radiation therapy offers advantages over photon therapy, assisting with severe side effect avoidance. Pediatric patients with medulloblastoma have demonstrated benefit from this technology in recently published cohort studies. OBJECTIVES: To compare the costs and benefits between proton and photon therapy in treating pediatric medulloblastoma. METHODS: The model was built with a lifetime horizon from the Brazilian health system perspective using a 3% discount rate. A microsimulation model was developed after a literature search, comparing scenarios of equipment life span and number of patients treated per year (50, 100, and 150 patients with 10, 25, and 20 years of equipment life span). The baseline parameters were 50 patients treated annually and 20 years of equipment life span. RESULTS: The quality-adjusted life-year gain was 2.71, and the average incremental cost-effectiveness ratio was $34 590.54 per quality-adjusted life-year. For the willingness-to-pay threshold of 1 gross domestic product per capita, it was observed that the incorporation of the technology would be cost-effective if more than 150 patients were treated per year. The weight of the equipment life span and other variables was limited when it varied in the sensitivity analysis, without significant changes to the model results. CONCLUSIONS: Proton therapy is not cost-effective for pediatric medulloblastoma treatment from the Brazilian health system perspective. The investment is not worth when considering the number of potential patients and the country dimensions.

[Breast cancer screening: modeling improvement of access using mobile mammography unitsSeguimiento del cáncer de mama: modelo de mejora del acceso con el uso de mamógrafos móviles]. / Rastreamento do câncer de mama: modelo de melhoria do acesso pelo uso de mamógrafos móveis.

OBJECTIVE: To investigate the impact of combined use of fixed and mobile mammography units to rationalize the management of breast cancer screening programs and increase population coverage. METHODS: An observational study was performed using agents-based modeling. The model was used to simulate breast cancer screening coverage in a specific region in the state of Rio de Janeiro (região serrana) where 22 fixed mammography units are installed. The number and distribution of fixed and mobile units, as well as the required number of daily exams, were estimated considering a population coverage of 100% and 60% in the region for the 2015-2016 biennium. RESULTS: For the two-year period, a 60% population coverage could be reached with eight mammography units (five fixed and three mobile). Considering a scenario in which 100% of the eligible population would undergo screening, 11 units would be required (seven fixed and four mobile units). The actual coverage in the region for the 2015-2016 biennium was 36.4%, with 22 mammography units performing four exams daily. CONCLUSIONS: The present simulation showed that it would be possible to reduce by half the number of mammography units in the region, ensuring 100% coverage. Adding more mobile units would facilitate access by the population from cities without installed mammography units and from rural areas.

OBJETIVO: Investigar la repercusión del uso conjunto de mamógrafos fijos y móviles para racionalizar la gestión de los programas de seguimiento del cáncer de mama, con el objeto de ampliar la cobertura de la población. MÉTODOS: Se realizó un estudio de observación con un modelo computacional basado en agentes. El modelo se utilizó para simular la cobertura mediante el seguimiento del cáncer de mama en la región serrana del estado de Rio de Janeiro (Brasil), donde se han instalado 22 mamógrafos fijos. Se estimaron el número y la distribución de mamógrafos fijos y móviles y el número de exámenes por día necesarios para lograr una cobertura de un 100% y de un 60% de la población de la región serrana en el bienio 2015-2016. RESULTADOS: Se determinó que, en el bienio objeto de estudio, se alcanzaría una cobertura de un 60% de la población con ocho mamógrafos (cinco fijos y tres móviles). En un escenario en el cual se haría el examen a un 100% de la población seleccionada, se necesitaría un total de 11 mamógrafos (siete fijos y cuatro móviles) en la región serrana. En el bienio citado, la cobertura real de la mamografía en dicha región fue de 36,4%, con la realización de cuatro exámenes diarios con 22 mamógrafos. CONCLUSIONES: Esta simulación mostró que sería posible reducir a la mitad el número de equipos existentes en la región estudiada y garantizar un 100% de cobertura. El uso de un mayor número de mamógrafos móviles facilitaría el acceso de la población en los municipios carentes de ese equipo y en las zonas rurales.

Mortalidade Cardiovascular Associada ao Rastreamento Mamográfico / Cardiovascular Mortality Associated with Mammographic Screening / Mortalidad Cardiovascular Asociada al Cribado Mamográfico

Introdução: Os danos cardiovasculares do rastreamento mamográfico não têm sido objeto de estudo ou preocupações, inclusive na área de cardio-oncologia. O resultado é uma importante lacuna na literatura a despeito de evidências da grande magnitude do sobrediagnóstico e do sobretratamento no rastreamento e sua ligação com aumento da mortalidade cardiovascular. Objetivo: Apresentar e discutir as principais evidências a respeito das causas de aumento de mortalidade cardiovascular associadas ao rastreamento. Método: Foram realizadas buscas sistemáticas na literatura, por meio de quatro estratégias de busca em duas bases de dados (MEDLINE e LILACS), para identificar as causas de aumento de mortalidade cardiovascular potencialmente associadas ao sobrediagnóstico e ao sobretratamento. Para cada uma das estratégias de busca, os resultados tiveram seu nível de evidência atribuídos de acordo com a classificação do Oxford Centre for Evidence-Based Medicine. Resultados: Dois grandes grupos de causas de aumento da mortalidade cardiovascular foram identificados: o primeiro ligado diretamente ao diagnóstico de câncer de mama; e o segundo ao tratamento do câncer de mama, incluindo cirurgia e radioterapia adjuvante. O aumento de mortalidade cardiovascular incluiu diversos subgrupos de causas, tais como infarto agudo do miocárdio, tromboembolismo pulmonar, insuficiência cardíaca, arritmias, doença orovalvar e acidente vascular encefálico. Conclusão: Existem evidências consistentes sobre mortalidade cardiovascular associada ao diagnóstico e ao tratamento do câncer de mama em situações clinicamente compatíveis com o rastreamento. É provável também que essa seja uma das causas mais importantes da mortalidade relacionada ao rastreamento, em especial aquelas associadas ao sobretratamento com radioterapia adjuvante.

Introduction: Cardiovascular harms of mammographic screening have not been the subject of study or concern, including in the cardio-oncology area of. The result is an important gap in literature despite the evidence of great magnitude of overdiagnosis and overtreatment in screening and its association with increased cardiovascular mortality. Objective: Present and discuss the main evidence regarding the causes of increased cardiovascular mortality associated with screening. Method: Systematic searches were performed in the literature through four search strategies in two databases (MEDLINE and LILACS), to identify the causes of increased cardiovascular mortality potentially associated with overdiagnosis and overtreatment. For each one of the search strategies, it was used the classification of the Oxford Centre for Evidence-Based Medicine to assign the level of evidence of the results. Results: Two major groups of causes of increased cardiovascular mortality were identified: the first linked directly to the diagnosis of breast cancer; and the second to the treatment of breast cancer, including surgery and adjuvant radiotherapy. The increase of cardiovascular mortality included several subgroups of causes such as acute myocardial infarction, pulmonary thromboembolism, heart failure, arrhythmias, heart valve disease and stroke. Conclusion: There are consistent evidence about cardiovascular mortality associated with breast cancer diagnosis and treatment in conditions clinically compatible with screening. It is also likely to be one of the most important causes of mortality related to screening, especially those associated with overtreatment with adjuvant radiotherapy.

Fuzzy Visa: um modelo de lógica fuzzy para a avaliação de risco da Vigilância Sanitária para inspeção de resíduos de serviços de saúde / Fuzzy Visa: a fuzzy logic model for risk assessment of Health Surveillance for health services waste inspection

Resumo A inspeção sanitária de Gerenciamento de Resíduos de Serviços de Saúde (GRSS) carece de metodologia de trabalho padronizada que proporcione bases seguras de avaliação de risco potencial (RP). O objetivo deste trabalho foi propor um instrumento baseado em lógica fuzzy capaz de padronizar a inspeção e gerar indicadores de controle sanitário. O modelo foi desenvolvido com 18 subsistemas relacionados ao GRSS, que resultaram da aglutinação de elementos identificados na inspeção, como aqueles que interferem na avaliação e permeiam todas as etapas do GRSS. A validação do modelo foi realizada em dez unidades de saúde no Rio de Janeiro, de maio a novembro de 2009. Os resultados obtidos no sistema seguiram os diagnósticos realizados pelos especialistas, mostrando a possibilidade de sistematização e racionalização das avaliações de RP. Esse sistema de apoio à decisão torna mais eficiente a gestão e o planejamento de ações na avaliação do RP.

Abstract The sanitary inspection of Health Services Waste Management (HSWM) lacks a standardized work methodology that provides a secure basis for evaluating potential risk (PR). This study aimed to propose an instrument based on fuzzy logic that could standardize inspection and generate indicators of sanitary control. The model was developed with 18 subsystems related to HSWM obtained from the assembly of elements identified in the inspection as those that interfere with the assessment and permeate all stages of HSWM. The validation of the model was conducted in 10 health establishments in Rio de Janeiro between May to November 2009. The results obtained by this model were consistent with the diagnoses made by experts and clearly indicated the possibility of the systematization and rationalization of PR assessments. This decision support system makes management and planning of actions more efficient in PR evaluation.
