Project description:BACKGROUND:Studies find that identifying additional study data is possible by contacting study authors or experts. What is less certain is the time taken, costs involved and value found by using this supplementary search method. The purpose of this study is to determine the effectiveness, efficiency, cost and value of contacting study authors by e-mail, updating the evidence available for this search method. METHODS:Eighty-eight study authors, whose studies met title/abstract inclusion in a. systematic review, were contacted by e-mail. * effectiveness was assessed by comparing the number of study authors contacted. compared to the number of replies received; * efficiency was assessed by recording the time taken to contact study authors; * cost was assessed by comparing the efficiency of contacting authors with the. effectiveness; and * value was assessed by reading and comparing the published studies with the replies received to see if any unique data was identified. RESULTS:Contacting study authors took 6 h, 54 min and 25 s across 7 weeks. 38 answers (46%) were received from 83 possible contacts. Contacting study authors cost £80.33 or £2.11 per reply. We identified unique data from author replies when compared with data reported in published studies, determining this method as 'valuable'. CONCLUSIONS:Whilst our effectiveness findings differ from other studies, we believe that this study demonstrates the effectiveness of contacting study authors. By linking effectiveness to value and cost, we offer a new way to interpret the 'effectiveness' of this supplementary search method.

Project description:The article offers a comparative analysis of the influence of cost-effectiveness thresholds in the decision-making processes in financing policies, coverage, and price regulation of health technologies in nine countries. We investigated whether countries used cost-effectiveness thresholds for public health policy decision making and found that few countries have adopted the cost-effectiveness threshold as an official criterion for financing, reimbursement, or pricing. However, in countries where it is applied, such as Thailand, the results have been very favorable in terms of minimizing health technology prices and ensuring the financial sustainability of the health system. Although the cost-effectiveness threshold has opportunities for improvement, particularly in certain institutional contexts and with adequate participation of the different strategic actors in the formulation of public policy, its potential use and added value are significant in various aspects.

Project description:BackgroundCost-effectiveness analysis can guide policymakers in resource allocation decisions. It assesses whether the health gains offered by an intervention are large enough relative to any additional costs to warrant adoption. When there are constraints on the health care system's budget or ability to increase expenditures, additional costs imposed by interventions have an "opportunity cost" in terms of the health foregone because other interventions cannot be provided. Cost-effectiveness thresholds (CETs) are typically used to assess whether an intervention is worthwhile and should reflect health opportunity cost. Nevertheless, CETs used by some decision makers-such as the World Health Organization that suggested CETs of 1 to 3 times the gross domestic product (GDP) per capita-do not.ObjectivesTo estimate CETs based on opportunity cost for a wide range of countries.MethodsWe estimated CETs based on recent empirical estimates of opportunity cost (from the English National Health Service), estimates of the relationship between country GDP per capita and the value of a statistical life, and a series of explicit assumptions.ResultsCETs for Malawi (the country with the lowest income in the world), Cambodia (with borderline low/low-middle income), El Salvador (with borderline low-middle/upper-middle income), and Kazakhstan (with borderline high-middle/high income) were estimated to be $3 to $116 (1%-51% GDP per capita), $44 to $518 (4%-51%), $422 to $1967 (11%-51%), and $4485 to $8018 (32%-59%), respectively.ConclusionsTo date, opportunity-cost-based CETs for low-/middle-income countries have not been available. Although uncertainty exists in the underlying assumptions, these estimates can provide a useful input to inform resource allocation decisions and suggest that routinely used CETs have been too high.

Project description:Background:Typhoid fever remains a major public health problem globally. While new Vi conjugate vaccines hold promise for averting disease, the optimal programmatic delivery remains unclear. We aimed to identify the strategies and associated epidemiologic conditions under which Vi conjugate vaccines would be cost-effective. Methods:We developed a dynamic, age-structured transmission and cost-effectiveness model that simulated multiple vaccination strategies with a typhoid Vi conjugate vaccine from a societal perspective. We simulated 10-year vaccination programs with (1) routine immunization of infants (aged <1 year) through the Expanded Program on Immunization (EPI) and (2) routine immunization of infants through the EPI plus a 1-time catch-up campaign in school-aged children (aged 5-14 years). In the base case analysis, we assumed a 0.5% case-fatality rate for all cases of clinically symptomatic typhoid fever and defined strategies as highly cost-effective by using the definition of a low-income country (defined as a country with a gross domestic product of $1045 per capita). We defined incidence as the true number of clinically symptomatic people in the population per year. Results:Vi conjugate typhoid vaccines were highly cost-effective when administered by routine immunization activities through the EPI in settings with an annual incidence of >50 cases/100000 (95% uncertainty interval, 40-75 cases) and when administered through the EPI plus a catch-up campaign in settings with an annual incidence of >130 cases/100000 (95% uncertainty interval, 50-395 cases). The incidence threshold was sensitive to the typhoid-related case-fatality rate, carrier contribution to transmission, vaccine characteristics, and country-specific economic threshold for cost-effectiveness. Conclusions:Typhoid Vi conjugate vaccines would be highly cost-effective in low-income countries in settings of moderate typhoid incidence (50 cases/100000 annually). These results were sensitive to case-fatality rates, underscoring the need to consider factors contributing to typhoid mortality (eg, healthcare access and antimicrobial resistance) in the global vaccination strategy.

Project description:Chronic liver disease and liver cancer associated with chronic hepatitis B (CHB) are leading causes of death among adults in China. Although newborn hepatitis B immunization has successfully reduced the prevalence of CHB in children, about 100 million Chinese adults remain chronically infected. If left unmanaged, 15-25% will die from liver cancer or liver cirrhosis. Antiviral treatment is not necessary for all patients with CHB, but when it is indicated, good response to treatment would prevent disease progression and reduce disease mortality and morbidity, and costly complications. The aim of this study is to analyze the cost-effectiveness of generic and brand antiviral drugs for CHB treatment in China, and assessing various thresholds at which a highly potent, low resistance antiviral drug would be cost-saving and/or cost-effective to introduce in a national treatment program. We developed a Markov simulation model of disease progression using effectiveness and cost data from the medical literature. We measured life-time costs, quality adjusted life years (QALYs), incremental cost-effectiveness ratios (ICERs), and clinical outcomes. The no treatment strategy incurred the highest health care costs ($12,932-$25,293) per patient, and the worst health outcomes, compared to the antiviral treatment strategies. Monotherapy with either entecavir or tenofovir yielded the most QALYs (14.10-19.02) for both HBeAg-positive and negative patients, with or without cirrhosis. Threshold analysis showed entercavir or tenofovir treatment would be cost saving if the drug price is $32-75 (195-460 RMB) per month, highly cost-effective at $62-110 (379-670 RMB) per month and cost-effective at $63-120 (384-734 RMB) per month. This study can support policy decisions regarding the implementation of a national health program for chronic hepatitis B treatment in China at the population level.

Project description:BackgroundMyocarditis is a major public health, social, and economic issue. Currently, few studies have provided comprehensive analyses of the global burden of myocarditis based on GBD (Global Burden Disease) 2021. We therefore analyzed long-term trends in the global burden of myocarditis from 1990 to 2021, described risk factors, examined the impact of COVID-19 (coronavirus infection disease 2019), and predicted future trends to inform health policy development and healthcare resource allocation.MethodFrom the GBD 2021 database, incident cases, deaths, and DALYs (disability-adjusted life years) were obtained for countries, regions, ages, and sexes globally. The estimated annual percentage change (EAPC) was used to analyze Trends in age-standardized rates of myocarditis and significant time points were examined using joinpoint regression analysis.ResultsGlobally, the age-standardized incidence rate (ASIR), DALYs rate (ASDALYsR), and death rate (ASDR) for myocarditis in 2021 were 16.16 [(13.11 to 19.76) per 100 000 people], 12.41 [10.37 to 14.76) per 100 000 people], and 0.40 [0.32 to 0.47) per 100 000 people], respectively. High-income Asia Pacific had the highest myocarditis ASIR in 2021, whereas Central Europe had the highest ASDALYsR and ASDR. Gender comparison showed myocarditis was more common in men. The burden of myocarditis was larger in the elderly aged 80 and older, but children should not be neglected. Analysis revealed a rise in worldwide ASIR from 2016 to 2021 (APC = 0.0945, 95%CI: 0.0709 to 0.1440, p < 0.001). During COVID-19, myocarditis burden did not peak. Both high and low temperatures increase myocarditis risk. The Bayesian age-period-cohort (BAPC) model predicted that myocarditis ASIR would rise while ASDALYsR and ASDR would decrease.ConclusionsThe global burden of myocarditis remains a health issue that cannot be ignored and shows significant regional and sex-based differences. Effective and targeted strategies for the prevention and management of myocarditis in this population are needed to reduce the overall burden.Clinical trial numberNot applicable.

Project description:BackgroundRabies is a viral zoonosis that imposes a substantial disease and economic burden in many developing countries. Dogs are the primary source of rabies transmission; eliminating dog rabies reduces the risk of exposure in humans significantly. Through mass annual dog rabies vaccination campaigns, the national program of rabies control in Mexico progressively reduced rabies cases in dogs and humans since 1990. In 2019, the World Health Organization validated Mexico for eliminating rabies as a public health problem. Using a governmental perspective, we retrospectively assessed the economic costs, effectiveness, and cost-effectiveness of the national program of rabies control in Mexico, 1990-2015.MethodologyCombining various data sources, including administrative records, national statistics, and scientific literature, we retrospectively compared the current scenario of annual dog vaccination campaigns and post-exposure prophylaxis (PEP) with a counterfactual scenario without an annual dog vaccination campaign but including PEP. The counterfactual scenario was estimated using a mathematical model of dog rabies transmission (RabiesEcon). We performed a thorough sensitivity analysis of the main results.Principal findingsResults suggest that in 1990 through 2015, the national dog rabies vaccination program in Mexico prevented about 13,000 human rabies deaths, at an incremental cost (MXN 2015) of $4,700 million (USD 300 million). We estimated an average cost of $360,000 (USD 23,000) per human rabies death averted, $6,500 (USD 410) per additional year-of-life, and $3,000 (USD 190) per dog rabies death averted. Results were robust to several counterfactual scenarios, including high and low rabies transmission scenarios and various assumptions about potential costs without mass dog rabies vaccination campaigns.ConclusionsAnnual dog rabies vaccination campaigns have eliminated the transmission of dog-to-dog rabies and dog-mediated human rabies deaths in Mexico. According to World Health Organization standards, our results show that the national program of rabies control in Mexico has been highly cost-effective.

Project description:ObjectivesCost-effectiveness analysis can guide decision making about health interventions, but the appropriate cost-effectiveness threshold to use is unclear in most countries. The World Health Organization (WHO) recommends vaccinating girls 9 to 14 years against human papillomavirus (HPV), but over half the world's countries have not introduced it. This study aimed to investigate whether country-level decisions about HPV vaccine introduction are consistent with a particular cost-effectiveness threshold, and to estimate what that threshold may be.MethodsThe cost-effectiveness of vaccinating 12-year-old girls was estimated in 179 countries using the Papillomavirus Rapid Interface for Modelling and Economics (PRIME) model, together with vaccine price data from World Health Organization's Market Information for Access to Vaccines database. In each year from 2006 to 2018, countries were categorized based on (1) whether they had introduced HPV vaccination, and (2) whether the incremental cost-effectiveness ratio for HPV vaccine introduction fell below a certain cost-effectiveness threshold.ResultsA cost-effectiveness threshold of 60% to 65% of GDP per capita has the best ability to discriminate countries that introduced vaccination, with a diagnostic odds ratio of about 7. For low-income countries the optimal threshold was lower, at 30% to 40% of GDP per capita.ConclusionsA cost-effectiveness threshold has some ability to discriminate between HPV vaccine introducer and non-introducer countries, although the average threshold is below the widely used threshold of 1 GDP per capita. These results help explain the current pattern of HPV vaccine use globally. They also inform the extent to which cost-effectiveness thresholds proposed in the literature reflect countries' actual investment decisions.

Project description:ObjectivesTo assess the distribution and spending by cost-effectiveness category among those drugs with the highest public spending levels in Canada.DesignRepeated cross-sectional study.SettingThe Canadian provinces of Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland.Main outcomes and measuresCost-effectiveness assessments by the Canadian Agency for Drugs and Technologies in Health (CADTH) for top-100 brand-name outpatient drugs by gross public plan spending in any year between 2015 and 2021 in Canada Institute for Health Information's National Prescription Drug Utilization Information System data. Gross public plan spending by cost-effectiveness category.ResultsFrom 2015 to 2021, 152 brand-name drugs occupied a top-100 rank and were included in the analysis. Of those, 117 had been assessed by CADTH. During the 7-year period, there was an increase in both top-100 drugs with cost-effective (from 18 to 24) and cost-ineffective (from 29 to 41) assessments, while drugs not assessed or with an unclear assessment declined (from 31 to 19 and from 22 to 16, respectively). As a share of spending on top-100 drugs with an assessment, spending on cost-effective drugs was mostly stable at 40%-46% from 2015 to 2021, while spending on cost-ineffective drugs increased from 30% to 45%.ConclusionA large and growing share of public drug spending has been allocated to cost-ineffective drugs in Canada. Dedicating large budgets to such treatments prevents spending with greater health impact elsewhere in the healthcare system and could restrain the capacity to pay for groundbreaking pharmaceutical innovation in the future.

Project description:BackgroundRecent updates to the Chinese guidelines for dyslipidemia management have reduced the 10-year risk threshold for starting statins in the primary prevention of atherosclerotic heart disease. This study aims to evaluate the potential negative effects of different statin initiation thresholds on diabetes risk in the Chinese population, while also analyzing their health economic implications.MethodsI We developed a microsimulation model based on event probabilities to assess the cost-effectiveness of statin therapy. The model utilized the China-PAR prediction tool for ASCVD risk and incorporated data from a nationally representative survey and published meta-analyses of middle-aged and elderly Chinese populations. Four strategies were evaluated: a 7.5% 10-year risk threshold, the current guideline strategy, and a 15% threshold. For each strategy, we calculated the incremental cost per quality-adjusted life year (QALY) to gain insights into the economic impact of each approach.ResultThe incremental cost per QALY for the 10% 10-year risk threshold strategy, compared to the untreated, was $52,218.75. The incremental cost per QALY for the guideline strategy, compared to the 7.5% 10-year risk threshold strategy, was $464,614.36. These results were robust in most sensitivity analyses.ConclusionMaintaining the recommended thresholds outlined in the current guidelines for the management of dyslipidemia may represent a cost-effective option for China at present. Variations in statin prices and the risk of statin-induced diabetes have significant impacts on the cost-effectiveness outcomes.
