Estimating the Effectiveness of Health Warnings on Cigarette Packaging in Nigeria: A Modeling Study.

INTRODUCTION: Tobacco consumption is associated with nearly 30 000 deaths annually in Nigeria alongside other adverse health and economic effects. Our objective was to estimate the health and economic implications of the current cigarette labeling policies (text-only HWs); new health warnings policies in the country (adding graphic health warnings with up to 60% coverage), and plain packaging policy as recommended by the World Health Organization. AIMS AND METHODS: We used a probabilistic state-transition individual microsimulation model, considering natural history, healthcare costs, and quality-of-life losses associated with main tobacco-attributable diseases; and the potential effects of packaging and labeling policies. We used three scenarios: (1) text-only health warnings (HWs) covering 50% of the pack, (2) introduction of graphic HWs of 50% (and later increasing to 80%) of the pack, and (3) plain packaging with HWs covering 80% of the pack. RESULTS: A total of 748 deaths are averted in the current situation; 7478 and 14 208 deaths can be averted with the new policy and with plain packaging, respectively. The number of cardiac, cerebrovascular, and cancer events that could be averted by adopting text and graphic HWs are 3093, 5093, and 1346, respectively; increasing to 5876, 9676, and 2557, respectively, with plain packaging. Up to 251 794 years were lost because of early deaths and disability, and ₦144.6 billion (USD 469 million) in health costs could be saved with HWs covering 50% to 80% of the pack over 10 years. With plain packaging and graphic HWs covering 80% of the package 478,408 years and ₦274.7 billion (USD 895 million) would be saved. CONCLUSIONS: The new cigarette labeling policy in Nigeria may yield significant health and economic benefits over 10 years. Moving the current policy to plain packaging can significantly improve these benefits. IMPLICATIONS: The new cigarette labeling policy that Nigeria is implementing should aim to achieve 100% compliance with its current regulation and the logical next step: Plain packaging with large warnings. The present study adds evidence of the potential health effects and cost savings of these levels of implementation, which is valuable for local policymakers.

Cost-effectiveness of COVID-19 vaccination in Latin America and the Caribbean: an analysis in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru.

OBJECTIVE: Our study analyzes the cost-effectiveness of the COVID-19 vaccination campaigns in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru. METHODS: Using a previously published SVEIR model, we analyzed the impact of a vaccination campaign (2021) from a national healthcare perspective. The primary outcomes were quality adjusted life years (QALYs) lost and total costs. Other outcomes included COVID-19 cases, hospitalizations, deaths, and life years. We applied a discount rate of 3% for health outcomes. We modeled a realistic vaccination campaign in each country (the realistic country-specific campaign). Additionally, we assessed a standard campaign (similar, "typical" for all countries), and an optimized campaign (similar in all countries with higher but plausible population coverage). One-way deterministic sensitivity analyses were performed. FINDINGS: Vaccination was health improving as well as cost-saving in almost all countries and scenarios. Our analysis shows that vaccination in this group of countries prevented 573,141 deaths (508,826 standard; 685,442 optimized) and gained 5.07 million QALYs (4.53 standard; 6.03 optimized). Despite the incremental costs of vaccination campaigns, they had a total net cost saving to the health system of US$16.29 billion (US$16.47 standard; US$18.58 optimized). The realistic (base case) vaccination campaign in Chile was the only scenario, which was not cost saving, but it was still highly cost-effective with an ICER of US$22 per QALY gained. Main findings were robust in the sensitivity analyses. INTERPRETATION: The COVID-19 vaccination campaign in seven Latin American and Caribbean countries -that comprise nearly 80% of the region- was beneficial for population health and was also cost-saving or highly cost-effective.

The health, economic and social burden of smoking in Argentina, and the impact of increasing tobacco taxes in a context of illicit trade.

Tobacco tax increases, the most cost-effective measure in reducing consumption, remain underutilized in low and middle-income countries. This study estimates the health and economic burden of smoking in Argentina and forecasts the benefits of tobacco tax hikes, accounting for the potential effects of illicit trade. Using a probabilistic Markov microsimulation model, this study quantifies smoking-related deaths, health events, and societal costs. The model also estimates the health and economic benefits of different increases in the price of cigarettes through taxes. Annually, smoking causes 45,000 deaths and 221,000 health events in Argentina, costing USD 2782 million in direct medical expenses, USD 1470 million in labor productivity loss costs, and USD 1069 million in informal care costs-totaling 1.2% of the national gross domestic product. Even in a scenario that considers illicit trade of tobacco products, a 50% cigarette price increase through taxes could yield USD 8292 million in total economic benefits accumulated over a decade. Consequently, raising tobacco taxes could significantly reduce the health and economic burdens of smoking in Argentina while increasing fiscal revenue.

Health, economic and social burden of tobacco in Latin America and the expected gains of fully implementing taxes, plain packaging, advertising bans and smoke-free environments control measures: a modelling study.

OBJECTIVE: To investigate the tobacco-attributable burden on disease, medical costs, productivity losses and informal caregiving; and to estimate the health and economic gains that can be achieved if the main tobacco control measures (raising taxes on tobacco, plain packaging, advertising bans and smoke-free environments) are fully implemented in eight countries that encompass 80% of the Latin American population. DESIGN: Markov probabilistic microsimulation economic model of the natural history, costs and quality of life associated with the main tobacco-related diseases. Model inputs and data on labour productivity, informal caregivers' burden and interventions' effectiveness were obtained through literature review, surveys, civil registrations, vital statistics and hospital databases. Epidemiological and economic data from January to October 2020 were used to populate the model. FINDINGS: In these eight countries, smoking is responsible each year for 351 000 deaths, 2.25 million disease events, 12.2 million healthy years of life lost, US$22.8 billion in direct medical costs, US$16.2 billion in lost productivity and US$10.8 billion in caregiver costs. These economic losses represent 1.4% of countries' aggregated gross domestic products. The full implementation and enforcement of the four strategies: taxes, plain packaging, advertising bans and smoke-free environments would avert 271 000, 78 000, 71 000 and 39 000 deaths, respectively, in the next 10 years, and result in US$63.8, US$12.3, US$11.4 and US$5.7 billions in economic gains, respectively, on top of the benefits being achieved today by the current level of implementation of these measures. CONCLUSIONS: Smoking represents a substantial burden in Latin America. The full implementation of tobacco control measures could successfully avert deaths and disability, reduce healthcare spending and caregiver and productivity losses, likely resulting in large net economic benefits.

Making visible the cost of informal caregivers' time in Latin America: a case study for major cardiovascular, cancer and respiratory diseases in eight countries.

BACKGROUND: Informal care is a key element of health care and well-being for society, yet it is scarcely visible and rarely studied in health economic evaluations. This study aims to estimate the time use and cost associated with informal care for cardiovascular diseases, pneumonia and ten different cancers in eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico and Peru). METHODS: We carried out an exhaustive literature review on informal caregivers' time use, focusing on the selected diseases. We developed a survey for professional caregivers and conducted expert interviews to validate this data in the local context. We used an indirect estimate through the interpolation of the available data, for those cases in which we do not found reliable information. We used the proxy good method to estimate the monetary value of the use of time of informal care. National household surveys databases were processed to obtain the average wage per hour of a proxy of informal caregiver. Estimates were expressed in 2020 US dollars. RESULTS: The study estimated approximately 1,900 million hours of informal care annually and $ 4,300 million per year in average informal care time cost for these fifteen diseases and eight countries analyzed. Cardiovascular diseases accounted for an informal care burden that ranged from 374 to 555 h per year, while cancers varied from 512 to 1,825 h per year. The informal care time cost share on GDP varied from 0.26% (Mexico) to 1.38% (Brazil), with an average of 0.82% in the studied American countries. Informal care time cost represents between 16 and 44% of the total economic cost (direct medical and informal care cost) associated with health conditions. CONCLUSIONS: The study shows that there is a significant informal care economic burden -frequently overlooked- in different chronic and acute diseases in Latin American countries; and highlights the relevance of including the economic value of informal care in economic evaluations of healthcare.

[Burden of disease and economic burden attributable to the consumption of sugar-sweetened beverages in El SalvadorCarga de morbidade e econômica atribuível ao consumo de bebidas açucaradas em El Salvador]. / Carga de enfermedad y económica atribuible al consumo de bebidas azucaradas en El Salvador.

Objective: To estimate the burden of disease and economic burden attributable to the consumption of sugar-sweetened beverages in El Salvador. Methods: A comparative risk model was used to estimate the effects on deaths, health events, disability-adjusted life years (DALYs), and direct medical costs attributable to the consumption of sugar-sweetened beverages. Results: A total of 520 deaths (8 per 100 000 individuals), 214 082 health events (3 220 per 100 000 individuals) and 16 643 DALYs could be attributable to the consumption of sugar-sweetened beverages in El Salvador, representing US$69.35 million in direct medical costs for the year 2020. In particular, type 2 diabetes (T2DM) events attributable to the consumption of sugar-sweetened beverages could represent more than 20% of total T2DM cases in the country. Conclusion: A high number of deaths, events, and costs could be attributed to the consumption of sugar-sweetened beverages in El Salvador.

Objetivo: Estimar a carga de morbidade e econômica atribuível ao consumo de bebidas açucaradas em El Salvador. Métodos: Foi utilizado um modelo de risco comparativo para estimar os efeitos sobre óbitos, eventos de saúde, anos perdidos devido a morte prematura ou vividos com incapacidade (AVAI) e custos médicos diretos atribuíveis ao consumo de bebidas açucaradas. Resultados: Um total de 520 mortes (8 por 100 00 indivíduos), 214 082 eventos de saúde (3 220 por 100 000 indivíduos) e 16 643 AVAI podem ser atribuídos ao consumo de bebidas açucaradas em El Salvador, o que representa US$ 69,35 milhões em custos médicos diretos para o ano de 2020. Os eventos de diabetes mellitus tipo 2 (DM2) atribuíveis ao consumo de bebidas açucaradas, em especial, podem representar mais de 20% do total de casos de DM2 no país. Conclusões: Um número elevado de mortes, eventos de saúde e custos pode ser atribuído ao consumo de bebidas açucaradas em El Salvador.

Health-Related Quality of Life in Patients with Breast Cancer in Latin America and the Caribbean: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Breast cancer (BC) is the most common cancer in women. It imposes a huge disease burden and a significant impact on health-related quality of life (HRQoL). Our study focused on HRQoL of patients with BC in Latin America and the Caribbean (LAC). We conducted a systematic review to identify relevant articles published between 2008 and August 2018. We conducted several meta-analyses and subgroup analyses by country, disease stage, and instrument used (Prospective Register Of Systematic Reviews registration number: CRD42018106835). RESULTS: From 2,265 initial references, we finally included 75 articles (8,806 participants) that assessed HRQoL. The European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire C30 and B23 modules (34 studies; 8 countries; 4,866 participants) were the most used instruments, followed by the Short Form 36-item, the abbreviated version of the World Health Organization Quality of Life instrument, and the Functional Assessment of Cancer Therapy - Breast instrument. Only four studies reported specific HRQoL data of patients with metastatic disease. Half the studies were rated as having moderate quality (38/75), and 38% (29/75) as high quality. We identified substantial heterogeneity. As expected, the meta-analyses revealed that patients with metastatic disease reported lower HRQoL values and high symptom burden compared with patients at earlier stages. Similar results can be observed when we compared patients with early breast cancer in active treatment phases versus those in follow-up. CONCLUSION: This study provides a synthesis of breast cancer HRQoL reported in LAC and exposes existing evidence gaps. Patients with BC in active treatment or with metastatic disease had worse HRQoL compared with survivors during the follow-up period. IMPLICATIONS FOR PRACTICE: This systematic review provides an exhaustive synthesis of breast cancer health-related quality of life in women in the Latin American and Caribbean region. Patients with breast cancer in active treatment or with metastatic disease had worse health-related quality of life compared with survivors during the different follow-up periods. This study also shows important evidence and methods gaps that can help inform future research.

Improving the monitoring of chronic heart failure in Argentina: is the implantable pulmonary artery pressure with CardioMEMS Heart Failure System cost-effective?

BACKGROUND: The CardioMEMS® sensor is a wireless pulmonary artery pressure device used for monitoring symptomatic heart failure (HF). The use of CardioMEMS was associated with a reduction of hospitalizations of HF patients, but the acquisition cost could be high in low-and-middle income countries. Evidence of cost-effectiveness is needed to help decision-makers to allocate resources according to "value for money". This study is aimed at estimating the cost-effectiveness of CardioMEMS used in HF patients from the third-party payer perspective -Social Security (SS) and Private Sector (PS)- in Argentina. METHODS: A Markov model was developed to estimate the cost-effectiveness of CardioMEMS versus usual medical care over a lifetime horizon. The model was applied to a hypothetical population of patients with HF functional class III with at least one hospitalization in the previous 12 months. The main outcome was the incremental cost-effectiveness ratio (ICER). To populate the model we retrieved clinical, epidemiological and utility parameters from the literature, whilst direct medical costs were estimated through a micro-costing approach (exchange rate USD 1 = ARS 76.95). Uncertainties in all parameters were assessed by deterministic, probabilistic and scenario sensitivity analysis. RESULTS: Compared with the usual medical care, CardioMEMS increased quality-adjusted life years (QALY) by 0.37 and increased costs per patient by ARS 1,081,703 for SS and ARS 919,051 for PS. The resultant ICER was ARS 2,937,756 per QALY and ARS 2,496,015 per QALY for SS and PS, respectively. ICER was most sensitive to the hazard ratio of HF hospital admission and the acquisition price of CardioMEMS. The probability that CardioMEMS is cost-effective at one (ARS 700,473), three (ARS 2,101,419,) and five (ARS 3,502,363) Gross Domestic Product per capita is 0.6, 17.9 and 64.1% for SS and 5.4, 33.3 and 73.2% for PS. CONCLUSIONS: CardioMEMS was more effective and more costly than usual care in class III HF patients. Since in Argentina there is no current explicit threshold, the final decision to determine its cost-effectiveness will depend on the willingness-to-pay for QALYs in each health subsector.

Sugar sweetened beverages attributable disease burden and the potential impact of policy interventions: a systematic review of epidemiological and decision models.

BACKGROUND: Around 184,000 deaths per year could be attributable to sugar-sweetened beverages (SSBs) consumption worldwide. Epidemiological and decision models are important tools to estimate disease burden. The purpose of this study was to identify models to assess the burden of diseases attributable to SSBs consumption or the potential impact of health interventions. METHODS: We carried out a systematic review and literature search up to August 2018. Pairs of reviewers independently selected, extracted, and assessed the quality of the included studies through an exhaustive description of each model's features. Discrepancies were solved by consensus. The inclusion criteria were epidemiological or decision models evaluating SSBs health interventions or policies, and descriptive SSBs studies of decision models. Studies published before 2003, cost of illness studies and economic evaluations based on individual patient data were excluded. RESULTS: We identified a total of 2766 references. Out of the 40 included studies, 45% were models specifically developed to address SSBs, 82.5% were conducted in high-income countries and 57.5% considered a health system perspective. The most common model's outcomes were obesity/overweight (82.5%), diabetes (72.5%), cardiovascular disease (60%), mortality (52.5%), direct medical costs (57.35%), and healthy years -DALYs/QALYs- (40%) attributable to SSBs. 67.5% of the studies modelled the effect of SSBs on the outcomes either entirely through BMI or through BMI plus diabetes independently. Models were usually populated with inputs from national surveys -such us obesity prevalence, SSBs consumption-; and vital statistics (67.5%). Only 55% reported results by gender and 40% included children; 30% presented results by income level, and 25% by selected vulnerable groups. Most of the models evaluated at least one policy intervention to reduce SSBs consumption (92.5%), taxes being the most frequent strategy (75%). CONCLUSIONS: There is a wide range of modelling approaches of different complexity and information requirements to evaluate the burden of disease attributable to SSBs. Most of them take into account the impact on obesity, diabetes and cardiovascular disease, mortality, and economic impact. Incorporating these tools to different countries could result in useful information for decision makers and the general population to promote a deeper implementation of policies to reduce SSBs consumption.

Need and inequality in the use of health care services in a fragmented and decentralized health system: evidence for Argentina.

BACKGROUND: The high fragmentation and decentralization in the provision of health care services that characterizes Argentina's health system, as well as the economic and social inequalities, challenge the achievement of the Universal Health Coverage (UHC). The objective of this study is to measure socioeconomic-related inequality and horizontal inequity in the use of health care services in Argentina as well as identify the factors that contribute to these disparities. METHODS: The 2013 National Risk Factor Survey, developed by the Ministry of Health of Argentina, was used to measure socioeconomic-related inequality and inequity in the use of health care services through concentration curves, the Erreygers concentration index, and the index of horizontal inequity. Econometric micro-decomposition was applied to estimate the contribution of each determining factor to inequality in the use of health care services. RESULTS: The Erreygers concentration index for the use of health care services was 0.1223, evidencing pro-rich inequalities. By adding variables of health care needs, the horizontal inequity index was 0.1296. Non-need factors such as education and health coverage with social security increase pro-rich inequality. CONCLUSIONS: The Argentine health system shows pro-rich inequality in the use of health care services. It is necessary to design strategies to improve articulation between the three coverage subsectors and national, provincial, and municipal governments to keep the commitment of "not leaving anyone behind." The results showed here could provide lessons for countries with similar contexts and challenges in public health.

Health and Economic Impact of Health Warnings and Plain Tobacco Packaging in Seven Latin American Countries: Results of a Simulation Model.

INTRODUCTION: The burden of disease attributable to tobacco use in Latin America is very high. Our objective was to evaluate the 10-year potential impact of current legislation related to cigarette packaging and warnings and expected effects of moving to a higher level of strategies implementing cigarette plain packaging on health and cost outcomes in Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru, using a microsimulation model. AIMS AND METHODS: We used a probabilistic state-transition microsimulation model, considering natural history, costs, and quality of life losses associated with main tobacco-related diseases. We followed up individuals in hypothetical cohorts and calculated health outcomes annually to obtain aggregated long-term population health outcomes and costs. We performed a literature review to estimate effects and analyzed studies and information from ministries, relevant organizations, and national surveys. We calibrated the model comparing the predicted disease-specific mortality rates with local statistics. RESULTS: Current graphic warnings already in place in each country could avert, during 10 years, 69 369 deaths and 638 295 disease events, adding 1.2 million years of healthy life and saving USD 5.3 billion in the seven countries. If these countries implemented plain packaging strategies, additional 155 857 premature deaths and 4 133 858 events could be averted, adding 4.1 million healthy years of life and saving USD 13.6 billion in direct health care expenses of diseases attributable to smoking. CONCLUSIONS: Latin American countries should not delay the implementation of this strategy that will alleviate part of the enormous health and financial burden that tobacco poses on their economies and health care systems. IMPLICATIONS: Tobacco smoking is the single most preventable and premature mortality cause in the world. The Framework Convention on Tobacco Control, supported by the World Health Organization, introduced a package of evidence-based measures for tobacco control. This study adds evidence on the potential health effects and savings of implementing cigarette plain packaging in countries representing almost 80% of the Latin American population; findings are valuable resources for policy makers in the region.

Alcohol consumption's attributable disease burden and cost-effectiveness of targeted public health interventions: a systematic review of mathematical models.

BACKGROUND: Around 6% of total deaths are related to alcohol consumption worldwide. Mathematical models are important tools to estimate disease burden and to assess the cost-effectiveness of interventions to address this burden. METHODS: We carried out a systematic review on models, searching main health literature databases up to July 2017. Pairs of reviewers independently selected, extracted data and assessed the quality of the included studies. Discrepancies were resolved by consensus. We selected those models exploring: a) disease burden (main metrics being attributable deaths, disability-adjusted life years, quality-adjusted life years) or b) economic evaluations of health interventions or policies, based on models including the aforementioned outcomes. We grouped models into broad families according to their common central methodological approach. RESULTS: Out of 4295 reports identified, 63 met our inclusion criteria and were categorized in three main model families that were described in detail: 1) State transition -i.e Markov- models, 2) Life Table-based models and 3) Attributable fraction-based models. Most studies pertained to the latter one (n = 29, 48.3%). A few miscellaneous models could not be framed into these families. CONCLUSIONS: Our findings can be useful for future researchers and decision makers planning to undertake alcohol-related disease burden or cost-effectiveness studies. We found several different families of models. Countries interested in adopting relevant public health measures may choose or adapt the one deemed most convenient, based on the availability of existing data at the local level, burden of work, and public health and economic outcomes of interest.

Cost-Effectiveness of a Comprehensive Approach for Hypertension Control in Low-Income Settings in Argentina: Trial-Based Analysis of the Hypertension Control Program in Argentina.

BACKGROUND: A recent cluster randomized trial evaluating a multicomponent intervention showed significant reductions in blood pressure in low-income hypertensive subjects in Argentina. OBJECTIVES: To assess the cost-effectiveness of this intervention. METHODS: A total of 1432 hypertensive participants were recruited from 18 primary health care centers. The intervention included home visits led by community health workers, physician education, and text messaging. Resource use and quality of life data using the three-level EuroQol five-dimensional questionnaire were prospectively collected. The study perspective was that of the public health care system, and the time horizon was 18 months. Intention-to-treat analysis was used to analyze cost and health outcomes (systolic blood pressure [SBP] change and quality-adjusted life-years [QALYs]). A 1 time gross domestic product per capita per QALY was used as the cost-effectiveness threshold (US $14,062). RESULTS: Baseline characteristics were similar in the two arms. QALYs significantly increased by 0.06 (95% confidence interval [CI] 0.04-0.09) in the intervention group, and SBP net difference favored the intervention group: 5.3 mm Hg (95% CI 0.27-10.34). Mean total costs per participant were higher in the intervention arm: US $304 in the intervention group and US $154 in the control group (adjusted difference of US $140.18; 95% CI US $75.41-US $204.94). The incremental cost-effectiveness ratio was $3299 per QALY (95% credible interval 1635-6099) and US $26 per mm Hg of SBP (95% credible interval 13-46). Subgroup analysis showed that the intervention was cost-effective in all prespecified subgroups (age, sex, cardiovascular risk, and body mass index). CONCLUSIONS: The multicomponent intervention was cost-effective for blood pressure control among low-income hypertensive patients.

[Cost-effectiveness of screening for colorectal cancer in Argentina.] / Costo-efectivided de las pruebas de tamizaje del cáncer colorectal en la Argentina.

International evidence show that screening for colorectal cancer is cost-effective; however, in Argentina is unknown. OBJECTIVE: The study shows the results of a cost-effectiveness evaluation based on two alternative mechanisms: annual faecal immunochemical testing (FIT), and colonoscopy every ten years in Argentina. METHODS: The study develops a Mar- kov model in ten stages, based on information provided by the INC, prior literature review and on-line questionnaires to physicians enrolled in the four major scientific societies related to cancer. Cost information arrived from the Na- tional Superintendence of Social Health Insurances and a sample of managers in social and private insurance schemes. RESULTS: The most cost-effective strategy consisted annual FIT, in comparison no intervention and colonoscopy every 10 years. The incremental cost effectiveness ratio (ICER) of FIT versus no intervention was of 980.5 pesos per QALY The findings were robust to deterministic sensitivity analysis. CONCLUSIONS: We confirmed that screening for CRC is a cost-effective intervention. Whereas the CCR is one of the leading causes of mortality in Argentina, these results support the widespread use of screening for CRC using anual FIT which proves to be highly cost effective for the country.

Budget impact analysis of venetoclax for the management of acute myeloid leukemia from the perspective of the social security and the private sector in Argentina.

OBJECTIVE: This study aimed to estimate the budget impact of the incorporation of venetoclax for the treatment of patients with Acute Myeloid Leukemia (AML) over 75 years of age or those with comorbidities and contraindications for the use of intensive chemotherapy, from the perspective of the social security and the private third-party payers in Argentina. METHODS: A budget impact model was adapted to estimate the cost difference between the current scenario (azacitidine, decitabine and low doses of cytarabine) and the new scenario (incorporation of venetoclax) for a third-party payer over a time horizon of three years. Input parameters were obtained from a literature review, validated or complemented by expert opinion using a modified Panel Delphi approach. All direct medical costs were estimated by the micro-costing approach and were expressed in US dollars (USD) as of September 2020 (1 USD = 76.18 Argentine pesos). RESULTS: For a third-party payer with a cohort of 1,000,000 individuals covered, incorporating venetoclax was associated with an average budget impact per-member per-month (PMPM) of $0.11 USD for the social security sector and $0.07 USD for the private sector. The duration of treatment with venetoclax was the most influential parameter in the budget impact results. CONCLUSION: The introduction of venetoclax was associated with a positive and slight budget impact. These findings are informative to support policy decisions aimed to expand the current treatment landscape of AML.

Discovery, synthesis and in combo studies of a tetrazole analogue of clofibric acid as a potent hypoglycemic agent.

A tetrazole isosteric analogue of clofibric acid (1) was prepared using a short synthetic route and was characterized by elemental analysis, NMR ((1)H, (13)C) spectroscopy, and single-crystal X-ray diffraction. The in vitro inhibitory activity of 1 against 11ß-hydroxysteroid dehydrogenase type 1 (11ß-HSD1) was evaluated, showing a moderate inhibitory enzyme activity (51.17% of inhibition at 10 µM), being more active than clofibrate and clofibric acid. The antidiabetic activity of compound 1 was determined at 50 mg/Kg single dose using a non insulin dependent diabetes mellitus rat model. The results indicated a significant decrease of plasma glucose levels, during the 7h post-administration. Additionally, we performed a molecular docking of 1 into the ligand binding pocket of one subunit of human 11ß-HSD1. In this model, compound 1 binds into the catalytic site of 11ß-HSD1 in two different orientations. Both of them, show important short contacts with the catalytic residues Ser 170, Tyr 183, Asp 259 and also with the nicotinamide ring of NADP(+).

A Systematic Review of Health Economic Evaluations and Budget Impact Analyses to Inform Healthcare Decision-Making in Central America.

BACKGROUND: Little is known about the quality, quantity and disease areas analysed by health economic research that inform healthcare decision-making in Central America. This study aimed to review the existing health economic evaluations (HEEs) and budget impact analyses (BIAs) evidence in Central America based on scope and reporting quality. METHODS: HEEs and BIAs published from 2000 to April 2021 were searched in five electronic databases: PubMed, Embase, LILACS (Latin American and Caribbean Health Science Literature), EconLIT and OVID Global Health. Two reviewers assessed titles, abstracts and full texts of studies for eligibility. The quality appraisal for the reporting was based on La Torre and colleagues' version of the Drummond checklist and the ISPOR good practices for BIA. For each country, we correlated the number of studies by disease area with their respective burden of disease to identify under-researched health areas. RESULTS: 102 publications were eligible for this review. Ninety-four publications reported a HEE, six publications reported a BIA, and two studies reported both a HEE and a BIA. Costa Rica had the highest number of publications (n = 28, 27.5%), followed by Guatemala (n = 25, 24.5%). Cancer and respiratory infections were the most common types of disease studied. Diabetes mellitus, chronic kidney diseases, and mental disorders were under-researched relative to their disease burden in most of the countries. The overall mean quality reporting score for HEE and BIA studies were 71/119 points (60%) and 7/10 points (70%), respectively; however, these assessments were made on different scales. CONCLUSION: In Central America, health economic research is sparse and is considered as suboptimal quality for reporting. The findings reported information useful to other low- and middle-income countries with similar advances in the application of economics to promote health policy decision-making.

Determining the efficiency path to universal health coverage: cost-effectiveness thresholds for 174 countries based on growth in life expectancy and health expenditures.

BACKGROUND: Assessment of the efficiency of interventions is paramount to achieving equitable health-care systems. One key barrier to the widespread use of economic evaluations in resource allocation decisions is the absence of a widely accepted method to define cost-effectiveness thresholds to judge whether an intervention is cost-effective in a particular jurisdiction. We aimed to develop a method to estimate cost-effectiveness thresholds on the basis of health expenditures per capita and life expectancy at birth and empirically derive these thresholds for 174 countries. METHODS: We developed a conceptual framework to assess how the adoption and coverage of new interventions with a given incremental cost-effectiveness ratio will affect the rate of increase of health expenditures per capita and life expectancy at the population level. The cost-effectiveness threshold can be derived so that the effect of new interventions on the evolution of life expectancy and health expenditure per capita is set within predefined goals. To provide guidance on cost-effectiveness thresholds and secular trends for 174 countries, we projected country-level health expenditure per capita and life expectancy increases by income level based on World Bank data for the period 2010-19. FINDINGS: Cost-effectiveness thresholds per quality-adjusted life-year (QALY) ranged between US$87 (Democratic Republic of the Congo) and $95 958 (USA) and were less than 0·5 gross domestic product (GDP) per capita in 96% of low-income countries, 76% of lower-middle-income countries, 31% of upper-middle-income countries, and 26% of high-income countries. Cost-effectiveness thresholds per QALY were less than 1 GDP per capita in 168 (97%) of the 174 countries. Cost-effectiveness thresholds per life-year ranged between $78 and $80 529 and between 0·12 and 1·24 GDP per capita, and were less than 1 GDP per capita in 171 (98%) countries. INTERPRETATION: This approach, based on widely available data, can provide a useful reference for countries using economic evaluations to inform resource-allocation decisions and can enrich international efforts to estimate cost-effectiveness thresholds. Our results show lower thresholds than those currently in use in many countries. FUNDING: Institute for Clinical Effectiveness and Health Policy (IECS).

Budget impact analysis of the freestyle libre flash continuous glucose monitoring system® in patients with diabetes mellitus type 1 in Chile.

OBJECTIVE: To estimate the budget impact of covering the FreeStyle Libre Flash Continuous Glucose Monitoring System (FSL) for type 1 Diabetes Mellitus patients (T1DM), compared to self-monitoring of blood glucose (SMBG), from the perspective of public and private third-party payers in Chile. METHODS: A budget impact model was developed to estimate the cost difference between SMBG and FSL over five years. Two FSL coverage schemes were assessed. Input parameters were retrieved from the literature review and complemented by expert opinion. Healthcare costs were estimated by a micro-costing approach and reported in USD. RESULTS: For a public sector third-party payer, incorporating FSL implied a cost increase up to USD 0.013 per member per month (PMPM) for the fifth year under the broad coverage scheme and a net saving of 0.0001 PMPM (all years) under the restricted coverage scheme. From a private sector third-party payer, incorporating FSL implied savings up to USD 0.028 PMPM (fifth year) for the broad coverage scheme and up to USD 0.012 PMPM (fifth year) for the restricted scheme. CONCLUSION: Incorporating the FSL for T1DM patients was associated with a marginal incremental cost for the public sector third-party payer and cost savings in Chile's private healthcare sector.
