BackgroundIn recent years, there has been growing awareness of the significant burden of Chagas disease in the United States (US). However, epidemiological data on both prevalence and access to care for this disease are limited. The objective of this study is to provide an updated national estimate of Chagas disease prevalence, the first state-level estimates of cases of T. cruzi infection in the US and to analyze these estimates in the context of data on confirmed cases of infection in the US blood supply.MethodsIn this study, we calculated estimates of the state and national prevalence of Chagas disease. The number of residents originally from Chagas disease endemic countries were computed using data on Foreign-Born Hispanic populations from the American Community Survey, along with recent prevalence estimates for Chagas disease in Latin America from the World Health Organization that were published in 2006 and updated in 2015. We then describe the distribution of estimated cases in each state in relation to the number of infections identified in the donated blood supply per data from the AABB (formerly American Association of Blood Banks).FindingsThe results of this analysis offer an updated national estimate of 238,091 cases of T. cruzi infection in the United States as of 2012, using the same method as was used by Bern and Montgomery to estimate cases in 2005. This estimate indicates that there are 62,070 cases less than the most recent prior estimate, though it does not include undocumented immigrants who may account for as many as 109,000 additional cases. The state level results show that four states (California, Texas, Florida and New York) have over 10,000 cases and an additional seven states have over 5,000 cases. Moreover, since 2007, the AABB has reported 1,908 confirmed cases of T. cruzi infection identified through screening of blood donations.ConclusionsThis study demonstrates a substantial burden of Chagas disease in the US, with state variation that reflects the distribution of at risk Latin American immigrant populations. The study lends important new insight into the distribution of this disease in the US and highlights the need for further research quantifying prevalence and incidence to guide interventions for control of Chagas disease across the US.

Analyzing antibiotic utilization in Latin America presents a series of challenges. Creating policy-relevant evidence based on antimicrobial consumption patterns is needed in order to foster policies aimed at improving appropriate use of antibiotics in the region.

Cardiovascular diseases (CVD) represent the highest burden of disease globally. Medicines are a critical intervention used to prevent and treat CVD. This review describes access to medication for CVD from a health system perspective and strategies that have been used to promote access including providing medicines at lower cost, improving medication supply, assuring medicine quality, promoting appropriate use, and managing intellectual property issues. Using key evidence in published and grey literature and systematic reviews, we summarize advances in access to cardiovascular medicines using the five health system dimensions of access: availability, affordability, accessibility, acceptability and quality of medicines. There are multiple barriers to access of cardiovascular disease medicines, particularly in low- and middle-income countries. Low availability of CVD medicines has been reported in public and private health care facilities. Where patients lack insurance and pay out-of-pocket to purchase medicines, they can be unaffordable. Accessibility and acceptability are low for medicines used in secondary prevention; increasing use is positively related to country income. Fixed-dose combinations (FDC) have shown a positive effect on adherence and intermediate outcome measures such as blood pressure and cholesterol. We have a new opportunity to improve access to CVD medicines by using strategies such as efficient procurement of low cost, quality-assured generic medicines, developing FDC medicines, and by promoting adherence through insurance schemes that waive copayment for chronic medications. Monitoring progress at all levels – institutional, regional, national, and international – is vital to identify gaps in access and implement adequate policies.

Key points for Decision Makers: European countries apply different pharmaceutical pricing and reimbursement policies. These policies are frequently assessed against their financial consequences and their ability to contain costs but less so in terms of access to medicines. Policies should be accompanied by regular evaluations, facilitated by the use of the appropriate methodology and access to the relevant data. There appears to be a need for additional changes beyond traditional pharmaceutical pricing and reimbursement policies. Collaborative approaches (e.g. between countries or between regulatory authorities, pricing and reimbursement agencies) and more transparency in terms of real medicine prices, R+D costs and medicines in the pipeline are considered as possible pathways for the future. AbstractThe paper discusses pharmaceutical pricing and reimbursement policies in European countries with regard to their ability to ensure affordable access to medicines. A frequently applied pricing policy is external price referencing. While it provides some benchmark for policy-makers and has shown to be able to generate savings, it may also contribute to delay in product launch in countries where medicine prices are low. Value-based pricing has been proposed as a policy that promotes access while rewarding useful innovation, however implementing it has proven quite challenging. For high-priced medicines, managed-entry agreements are increasingly used. These agreements allow policy-makers to manage uncertainty and obtain lower prices. They can also facilitate earlier market access in case of limited evidence about added therapeutic value of the medicine. However, these agreements raise transparency concerns due to the confidentiality clause. Tendering as used in the 2 hospital and offpatent outpatient sectors has proven to reduce medicine prices but it requires a robust framework and appropriate design with clear strategic goals in order to prevent shortages. These pricing and reimbursement policies are supplemented by the widespread use of Health Technology Assessment to inform decision-making, and by strategies to improve the uptake of generics, and also biosimilars. While European countries have been implementing a set of policy options, there is a lack of thorough impact assessments of several pricing and reimbursement policies on affordable access. Increased cooperation between authorities, experience sharing, and improving transparency on price information, including the disclosure of confidential discounts, are opportunities to address current challenges.3
