ArticlePublication 2007Multiparameter Calibration of a Natural History Model of Cervical Cancer
This paper presents a two-step approach to model calibration of a comprehensive natural history model …
This paper presents a two-step approach to model calibration of a comprehensive natural history model of human papillomavirus (HPV) and cervical cancer. Using primary epidemiologic data from a longitudinal study of women in Brazil, a plausible range for each input parameter was identified that would produce model output within the 95% confidence intervals of the data. The authors then performed a simultaneous search over all input parameters to identify parameter sets that produced output consistent…

ArticlePublication 2022Spatial-Mechanistic Model to Estimate Sub-National Tuberculosis Burden in Brazilian Municipalities
Reliable subnational estimates of TB incidence are needed to focus disease control resources in areas …
Reliable subnational estimates of TB incidence are needed to focus disease control resources in areas of highest need. This study developed an approach for generating small area estimates of TB incidence, and the fraction of individuals missed by routine case detection, based on available notification and mortality data. The approach is demonstrated by estimating TB outcomes for 5568 municipalities in Brazil, revealing substantial subnational differences in disease burden and other metrics useful for designing high-impact…

ArticlePublication 2022Early HPV Natural History Transitions
Microsimulation models used to evaluate the cost-effectiveness of novel cervical cancer screening technologies rely on …
Microsimulation models used to evaluate the cost-effectiveness of novel cervical cancer screening technologies rely on accurate transition risks for human papillomavirus (HPV) infection, persistence (or absence of HPV clearance), progression to precancerous lesions, and invasion. To inform the refinement of such models, we compared the early natural history of HPV types using prospective data from immunocompetent women in the Guanacaste Natural History Study, the ASCUS-LSIL Triage Study, and the Costa Rica HPV Vaccine Trial. We…

ArticlePublication 2022Distributional Effects of Tobacco Tax Increases across Mexico: An ECEA
This study examines the distributional impacts of a one-peso tobacco tax increase in Mexico, focusing …
This study examines the distributional impacts of a one-peso tobacco tax increase in Mexico, focusing on health, poverty, and financial outcomes at the subnational level. Utilizing an extended cost-effectiveness analysis, the research estimates various metrics such as life-years gained, smoking attributable deaths averted, treatment costs averted, and financial impacts by income group across five regions. Findings reveal that the tax increase would lead to significant benefits, including approximately 1.5 million smokers quitting across the regions,…

ArticlePublication 2021Distributional Health and Financial Consequences of Increased Cigarette Tax in Iran: An ECEA
This study examines the potential impact of a tax-induced cigarette price increase on financial and …
This study examines the potential impact of a tax-induced cigarette price increase on financial and health outcomes across different socioeconomic groups in Iran. Using pooled cross-sectional data from Household Income and Expenditure Surveys (2002–2017) and population data from Iran in 2019, an extended cost-effectiveness analysis (ECEA) methodology is employed to model the effects of a hypothetical increase in cigarette tax. The analysis evaluates health benefits, health expenditures averted, additional tax revenues generated, changes in household…

ArticlePublication 2018HTA and MCDA Solely or Combined? The Case of Priority-Setting in Colombia
Given the limited resources available worldwide, healthcare systems face problems of justice and efficiency related …
Given the limited resources available worldwide, healthcare systems face problems of justice and efficiency related to setting priorities. Two methods, Health Technology Assessment (HTA) and Multi-Criteria Decision Analysis (MCDA) have emerged as tools to assist in informed decision-making, but both have advantages and disadvantages. Colombia established a Health Technology Assessment Institute in 2012. The authors discuss challenges faced by the Colombian health system, characteristics of HTA in Colombia and the potential benefits and drawbacks of…

ArticlePublication 2018Equity Impact Vaccines May Have on Averting Deaths and Medical Impoverishment
In this analysis, authors estimated the number of deaths averted and the number of cases …
In this analysis, authors estimated the number of deaths averted and the number of cases of medical impoverishment averted of ten antigens and their corresponding vaccines across income quintiles for forty-one low- and middle-income countries. The study found that vaccines administered between 2016 and 2030 would prevent 36 million deaths. Vaccines will have the greatest impact on reducing cases of poverty caused by hepatitis B, helping an estimated 14 million people avoid medical impoverishment. An…

ArticlePublication 2017Cost Determinants of Routine Infant Immunization Services
The EPIC study collected data on routine infant immunization costs from Benin, Ghana, Honduras, Moldova, …
The EPIC study collected data on routine infant immunization costs from Benin, Ghana, Honduras, Moldova, Uganda, Zambia, using a standardized approach. The authors estimated how costs were distributed across budget categories and programmatic activities, and investigated how the cost structure of immunization sites varied by country and site characteristics. For each country, the economic costs of infant immunization were estimated by administrative level, budget category, and programmatic activity from a program perspective. Regression models were…

ArticlePublication 2016Cost-Effectiveness of Routine Vaccination With a Live-Attenuated Dengue Vaccine: Model Comparison
Large Phase III trials across Asia and Latin America have demonstrated the efficacy of a recombinant, …
Large Phase III trials across Asia and Latin America have demonstrated the efficacy of a recombinant, live-attenuated dengue vaccine (Dengvaxia) over the first 25 months following vaccination. Subsequent data collected in the longer-term follow-up phase, however, have raised concerns about a potential increase in hospitalization risk of subsequent dengue infections, in particular among young, dengue-naïve vaccinees. This paper reports predictions from eight independent modelling groups on the long-term safety, public health impact, and cost-effectiveness of routine…
