Purpose Obesity is associated with increased morbidity and mortality. Weight loss due to gastric bypass (GBP) surgery improves clinical outcomes and may be a cost-effective intervention. To estimate the cost-effectiveness of GBP compared to clinical treatment in severely obese individuals with and without diabetes in the perspective of the Brazilian public health system. Materials and Methods A Markov model was developed to compare costs and outcomes of gastric bypass in an open approach to clinical treatment. Health states were living with diabetes, remission of diabetes, non-fatal and fatal myocardial infarction, and death. We also included the occurrence of complications related to surgery and plastic surgery after the gastric bypass surgery. The direct costs were obtained from primary data collection performed in three public reference centers for obesity treatment. Utility values also derived from this cohort, while transition probabilities came from the international literature. A sensitivity analysis was performed to evaluate uncertainties. The model considered a 10-year time horizon and a 5% discount rate. Results Over 10 years, GBP increased quality-adjusted life years (QALY) and costs compared to clinical treatment, resulting in an incremental cost-effectiveness ratio (ICER) of Int$1820.17/QALY and Int$1937.73/QALY in individuals with and without diabetes, respectively. Sensitivity analysis showed that utility values and direct costs of treatments were the parameters that affected the most the ICERs. ConclusionThe study demonstrated that GBP is a cost-effective intervention for severely obese individuals in the Brazilian public health system perspective, with a better result in individuals with diabetes.

A simple adjustment in vial size may reduce the waste of bortezomib by 36% to 62% and can also reduce the cost of treatment.

Life expectancy has increased over the last century as it had never been before. This is the result of a combination of many favorable variables such as level of education, improved socio-economic environment and development of medicine. However, new improvements demand heavy investment. Thus, the incorporation of medical technology became a health and economic issue. The pharmacoeconomic knowledge field is being developed to help in the analysis of medical costs and patient needs. The applies to hepatitic C, a common and chronic worldwide disease. In this article, the authors describe the rational behind this type of health economic analysis and review a hepatitis C model. Overall, in a non-Brazilian scenario, it was demonstrated that peginterferon alfa-2a (40KD) is cost effective in the treatment of HCV disease.

Background and purpose: RESILIENT Trial was the first study in a developing country to demonstrate the benefit of mechanical thrombectomy (MT) in acute stroke patients. This economic evaluation aimed to access the cost-utility of MT under the perspective of the Brazilian Public Healthcare System. Methods: Analysis was based on a subset sample of the original study (151 of 221 patients) from 4 hospitals. We compared costs and utilities between MT plus standard care (n=78) vs. standard care alone (n=73). Direct medical costs were considered, and utilities were inputted according to each patient’s Utility-Weighted modified Rankin Score (UW-mRS). First-year survival was obtained from trial follow-up and modelled for a life-time horizon adjusted by National Mortality Data. Direct medical costs were converted to I$ using Purchasing Power Parity (PPP). A discount rate of 5% was used. Incremental cost-effectiveness ratio (ICER) is expressed in cost (I$) per Quality-Adjusted Life Year (QALY). Results: RESILIENT trial was stopped on its first interim analysis because of early efficacy. The incremental costs and QALYs gained with MT were estimated at I$ 8,369 and 0.75, respectively, compared with standard medical care, yielding an incremental cost-effectiveness ratio (ICER) of I$ 7,256 per QALY. Conclusion: The initially higher costs of MT were offset by the clear benefit of the intervention. RESILIENT trial demonstrated that such therapy is likely to be cost-effective despite the economical constraints in the Brazilian healthcare system.
