We derived the EQ-5D-5L Uruguayan value set, the first in Latin America. These results will help inform decision-making using economic evaluations for resource allocation decisions.
Although CE in other settings, trastuzumab was not CE in LA. The use of health technology assessment to prioritize resource allocation and support price negotiations is critical to making innovative drugs available and affordable in developing countries.
ObjectiveTo estimate the impact of Argentine policies to reduce trans fatty acids (TFA) on coronary heart disease (CHD), disability-adjusted life years (DALYs) and associated health-care costs.MethodsWe estimated the baseline intake of TFA before 2004 to be 1.5% of total energy intake. We built a policy model including baseline intake of TFA, the oils and fats used to replace artificial TFAs, the clinical effect of reducing artificial TFAs and the costs and DALYs saved due to averted CHD events. To calculate the percentage of reduction of CHD, we calculated CHD risks on a population-based sample before and after implementation. The effect of the policies was modelled in three ways, based on projected changes: (i) in plasma lipid profiles; (ii) in lipid and inflammatory biomarkers; and (iii) the results of prospective cohort studies. We also estimated the present economic value of DALYs and associated health-care costs of coronary heart disease averted.FindingsWe estimated that projected changes in lipid profile would avert 301 deaths, 1066 acute CHD events, 5237 DALYs and 17 million United States dollars (US$) in health-care costs annually. Based on the adverse effects of TFA intake reported in prospective cohort studies, 1517 deaths, 5373 acute CHD events, 26 394 DALYs and US$ 87 million would be averted annually.ConclusionEven under the most conservative scenario, reduction of TFA intake had a substantial effect on public health. These findings will help inform decision-makers in Argentina and other countries on the potential public health and economic impact of this policy.
The risks of severe leukopenia and agranulocytosis have varied over time and among geographical regions and cultures, with little information available on South American populations. Accordingly, we reviewed and analyzed data from a 6-year experience monitored by an Argentine national registry to which reporting of adverse events reports is required. We analyzed data for 2007-2012 from the pharmacovigilance program of the Argentine drug-regulatory agency (ANMAT) using standard bivariate and multivariate statistical methods and survival analysis. We identified 378 cases of adverse hematological events over 6 years among an average of 12 305 individuals/year treated with clozapine (308±133 mg/day) to estimate the mean annualized rates of leukopenia [0.19 (95% confidence interval [CI] 0.11-0.27)], neutropenia [0.38 (95% CI 0.34-0.43)], and agranulocytosis [0.05 (95% CI 0.02-0.08)] % per year [median latency 2 (95% CI 1.3-2.1) months]; fatalities related to agranulocytosis averaged 4.2 (95% CI 0.0-9.2) per 100 000 treated individuals/year. Factors associated significantly and independently with agranulocytosis were female sex, older age, and use of other drugs in addition to clozapine. With monitoring by international standards, recent risks of clozapine-associated agranulocytosis in Argentina were lower, but fatality rates were higher than that in other regions of the world. Risk factors include the use of multiple psychotropic drugs, female sex, and older age.
Background
The treatment of choice for advanced non–small cell lung cancer is selected according to the presence of specific alterations. Patients should undergo molecular testing for relevant modifications and the mutational status of EGFR and translocation of ALK and ROS1 are commonly tested to offer the best intervention. In addition, the tests costs should also be taken in consideration. Therefore, this work was performed in order to evaluate the cost-effectiveness of a unique exam using NGS (next generation sequencing) versus other routinely used tests which involve RT-PCR and FISH.
Methods
The target population was NSCLC, adenocarcinoma, and candidates to first-line therapy. Two strategies were undertaken, strategy 1 corresponded to sequential tests with EGFR RT-PCR, then FISH for ALK and ROS1. Strategy 2 differed from 1 in that ALK and ROS1 translocation testing were performed simultaneously by FISH. Strategy 3 considered single test next-generation sequencing, a platform that includes EGFR, ALK and ROS1 genes. A decision tree analysis was used to model genetic testing options. From the test results, a microsimulation model was nested to estimate survival outcomes and costs of therapeutic options.
Results
The use of NGS added 24% extra true cases as well as extra costs attributed to the molecular testing. The ICER comparing NGS with sequential tests was US$ 3479.11/correct case detected. The NGS improved a slight gain in life years and QALYs.
Conclusion
Our results indicated that, although precise, the molecular diagnosis by NGS of patients with advanced stage NSCLC adenocarcinoma histology was not cost-effective in terms of quality-adjusted life years from the perspective of the Brazilian supplementary health system.
