Perda de Produtividade Atribuída a Neoplasias na América do Sul / Lost Productivity Attributed to Neoplasms in South America / Pérdida de Productividad Atribuida a Neoplasias en América del Sur

Introdução: A carga da doença tem sido empregada em estimativas do impacto das neoplasias, mas a perda de produtividade em razão dessas enfermidades ainda não foi tão explorada. Objetivo: Estimar os anos de vida produtiva perdidos (AVPP) e a perda de produtividade por conta da mortalidade prematura relacionada ao câncer em países da América do Sul em 2019. Método: Dados de mortalidade disponíveis no Global Burden of Disease (GBD) Study 2019 foram usados para estimar a carga de doença atribuível a neoplasias. A perda de produtividade em termos monetários foi calculada usando um proxy da abordagem do capital humano (ACH). Os cálculos foram realizados por sexo, nas faixas etárias de trabalho. Resultados: O total de óbitos foi de 192.240 e o de AVPP, 2.463.155. A perda total de produtividade permanente foi de US$ 4,4 bilhões e US$ 9,4 bilhões em purchasing power parity (PPP) ­ 0,13% do produto interno bruto (PIB) da região. O custo total por morte foi de US$ 23.617. Houve diferenças significativas entre os países, mas a variação dos cenários mostra robustez das estimativas. Conclusão: O câncer impõe um ônus econômico significativo à América do Sul tanto em termos de saúde quanto de produtividade. Sua caracterização pode subsidiar os governos na alocação de recursos destinados ao planejamento de políticas e execução de intervenções de saúde

Introduction: The burden of the disease has been utilized in estimates of the impact of neoplasms, but the loss of productivity due to these diseases has not yet been explored. Objective: To estimate the years of productivity life lost (YPLL) and lost productivity due to premature cancer-related mortality in South American countries in 2019. Method: Mortality data available from Global Burden of Disease (GBD) Study 2019 was analyzed to estimate the burden attributable to neoplasms. The productivity loss in monetary terms was estimated using a proxy of the human capital approach (HCA). Calculations were performed by sex, in working age groups. Results: The total deaths and YPLL reached 192,240 and 2.463.155, respectively. The total permanent productivity loss was around US$ 4.4 billion and US$ 9.4 billion in purchasing power parity (PPP) ­ 0.13% of the continent's gross domestic product (GDP). Total cost per death was US$23,617. There were significant differences among countries, but the variation of scenarios shows robustness of the estimates. Conclusion: Cancer imposes a significant economic burden on South American, both in terms of health and productivity. Its characterization can help governments to allocate resources for policies planning and health interventions.

Economic Analyses of Respiratory Tract Infection Diagnostics: A Systematic Review.

BACKGROUND: Diagnostic testing for respiratory tract infections is a tool to manage the current COVID-19 pandemic, as well as the rising incidence of antimicrobial resistance. At the same time, new European regulations for market entry of in vitro diagnostics, in the form of the in vitro diagnostic regulation, may lead to more clinical evidence supporting health-economic analyses. OBJECTIVE: The objective of this systematic review was to review the methods used in economic evaluations of applied diagnostic techniques, for all patients seeking care for infectious diseases of the respiratory tract (such as pneumonia, pulmonary tuberculosis, influenza, sinusitis, pharyngitis, sore throats and general respiratory tract infections). METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, articles from three large databases of scientific literature were included (Scopus, Web of Science and PubMed) for the period January 2000 to May 2020. RESULTS: A total of 70 economic analyses are included, most of which use decision tree modelling for diagnostic testing for respiratory tract infections in the community-care setting. Many studies do not incorporate a generally comparable clinical outcome in their cost-effectiveness analysis: fewer than half the studies (33/70) used generalisable outcomes such as quality-adjusted life-years. Other papers consider outcomes related to the accuracy of the test or outcomes related to the prescribed treatment. The time horizons of the studies generally are limited. CONCLUSIONS: The methods to economically assess diagnostic tests for respiratory tract infections vary and would benefit from clear recommendations from policy makers on the assessed time horizon and outcomes used.

Availability of biological cancer drugs under research: registration and price in Brazil, Colombia, and Mexico / Disponibilidade de medicamentos biológicos contra o câncer: registro e preço no Brasil, Colômbia e México

Abstract This study seeks to understand biological cancer drug availability through registration and prices of the biological agents used for cancer therapy and authorized for sale in the last 5 years in Brazil, Colombia, and Mexico, comparing the data to those for the United States of America (USA) and Spain. The regulatory agencies' websites were assessed for drugs registered between January 1, 2014, and February 20, 2019. Drug prices were sought in the clerical databases. Prices were also compared using purchasing power parity (PPP). The comparison between the purchasing power (PP) of the three Latin American countries is hampered by market heterogeneity and uncertainty in the data. There is no registration synchronization. The average difference between the launch time in the USA and in the other countries is 1.6 to 2.6 years. The USA has the lowest PPP values, compared to the Latin American countries studied, but higher prices. Differences in registration time reveal issues in drug access in the Latin American countries studied or a lack of equity between countries. The economic effort that these countries make to have access to these supplies is much higher than that of the USA and Spain.

Resumo Este estudo busca entender a disponibilidade de medicamentos contra o câncer biológico por meio do registro e preços dos agentes biológicos utilizados na terapia do câncer e autorizados para venda nos últimos cinco anos no Brasil, Colômbia e México, comparando os dados com os dos Estados Unidos da América (EUA) e Espanha. Os sites das agências reguladoras foram consultados para medicamentos registrados entre 1º de janeiro de 2014 e 20 de fevereiro de 2019. Os preços dos medicamentos foram procurados nas bases de dados administrativas. Os preços também foram comparados usando a paridade do poder de compra (PPP). A comparação entre o poder de compra (PP) dos três países da América Latina é dificultada pela heterogeneidade de mercado e incerteza nos dados. Não há sincronização de registro. A diferença média entre o tempo de lançamento nos EUA e nos outros países é de 1,6 a 2,6 anos. Os EUA têm os menores valores de PPP, em comparação com os países latino-americanos estudados, mas preços mais altos. As diferenças no tempo de registro revelam problemas no acesso a medicamentos nos países latino- americanos estudados ou falta de equidade entre os países. O esforço econômico que esses países fazem para ter acesso a esses suprimentos é muito maior do que o dos EUA e da Espanha.

[Mathematical models for economic evaluation: dynamic models based on differential equations]. / Modelos matemáticos para la evaluación económica: los modelos dinámicos basados en ecuaciones diferenciales.

The joint utilization of both decision trees and epidemiological models based on differential equations is an appropriate method for the economic evaluation of preventative interventions applied to infectious diseases. These models can combine the dynamic pattern of the disease together with health resource consumption. To illustrate this type of model, we adjusted a dynamic system of differential equations to the epidemic behavior of influenza in Spain, with a view to projecting the epidemiologic impact of influenza vaccination. The results of the epidemic model are implemented in a diagram with the structure of a decision tree so that health resource consumption and the economic implications can be calculated.

Cost-utility analysis of eprosartan compared to enalapril in primary prevention and nitrendipine in secondary prevention in Europe--the HEALTH model.

OBJECTIVE: To investigate the cost-utility of eprosartan versus enalapril (primary prevention) and versus nitrendipine (secondary prevention) on the basis of head-to-head evidence from randomized controlled trials. METHODS: The HEALTH model (Health Economic Assessment of Life with Teveten for Hypertension) is an object-oriented probabilistic Monte Carlo simulation model. It combines a Framingham-based risk calculation with a systolic blood pressure approach to estimate the relative risk reduction of cardiovascular and cerebrovascular events based on recent meta-analyses. In secondary prevention, an additional risk reduction is modeled for eprosartan according to the results of the MOSES study ("Morbidity and Mortality after Stroke--Eprosartan Compared to Nitrendipine for Secondary Prevention"). Costs and utilities were derived from published estimates considering European country-specific health-care payer perspectives. RESULTS: Comparing eprosartan to enalapril in a primary prevention setting the mean costs per quality adjusted life year (QALY) gained were highest in Germany (Euro 24,036) followed by Belgium (Euro 17,863), the UK (Euro 16,364), Norway (Euro 13,834), Sweden (Euro 11,691) and Spain (Euro 7918). In a secondary prevention setting (eprosartan vs. nitrendipine) the highest costs per QALY gained have been observed in Germany (Euro 9136) followed by the UK (Euro 6008), Norway (Euro 1695), Sweden (Euro 907), Spain (Euro -2054) and Belgium (Euro -5767). CONCLUSIONS: Considering a Euro 30,000 willingness-to-pay threshold per QALY gained, eprosartan is cost-effective as compared to enalapril in primary prevention (patients >or=50 years old and a systolic blood pressure >or=160 mm Hg) and cost-effective as compared to nitrendipine in secondary prevention (all investigated patients).

[Use of European Quality of Life-5 Dimensions (EQ-5D) questionnary to value the health related quality of life variation because of influenza]. / Utilización del cuestionario European Quality of Life-5 Dimensions (EQ-5D) para valorar la variación de la calidad de vida relacionada con la salud debida a la gripe.

OBJECTIVE: To describe self-perceived health status and health-related quality of life (HRQoL) in healthy individuals of working age, to measure changes due to influenza infection, and to evaluate the effect of influenza infection on HRQoL in monetary terms. METHOD: We performed a descriptive observational study through questionnaires administered to 50 patients of working age infected with the influenza virus during the epidemiologic year 2004-2005 and living in private homes of the city of Logroño (Spain). The patients completed the questionnaires twice: with and without influenza. The dimensions and HRQoL indicators of the European Quality of Life-5 Dimensions (EQ-5D) questionnaire were evaluated. HRQoL utility indices were used to calculate lost quality-adjusted life years (QALYs). RESULTS: On average, the reduction in the HRQoL utility index caused by influenza infection was between 0.37 and 0.65, on a scale from 0 (death) to 1 (perfect health). An influenza epidemic in 100,000 individuals could imply a loss of 137 QALYs, which in monetary terms could represent 2,722,609euro. CONCLUSIONS: The EQ-5D dimension most negatively affected by influenza was <> while the least affected dimension was <>. Influenza causes substantial losses in HRQoL among the population of working age. The results of the sensitivity analysis of the monetary effects of influenza infection yielded intervals showing a range of more than 5 times the mean value.
