ArticlePublication 2002Empirically Calibrated Model of Hepatitis C Virus Infection in the United States
This article presents an epidemiologic model of hepatitis C in the United States. The authors …
This article presents an epidemiologic model of hepatitis C in the United States. The authors used empirical calibration of model parameters to gain insights into uncertainty in the natural history of hepatitis C and to improve future projections. The authors identified model inputs by way of a systematic review. Model simulations were conducted and model predictions were compared with epidemiologic data on infection prevalence and mortality from liver cancer. Goodness-of-fit criteria were used to identify…

Working PaperPublication 2024Economic Evaluation Primer
Economic evaluation is a powerful tool, encouraging the systematic collection and assessment of the evidence …
Economic evaluation is a powerful tool, encouraging the systematic collection and assessment of the evidence needed to support sound policy decisions. In low- and middle-income countries, where resources are especially scarce and needs are very great, such decisions are exceptionally difficult. In these settings, economic evaluation can be particularly useful in determining how to best improve health and welfare. Typically, cost-effectiveness analysis (CEA) is used to prioritize interventions within the health care sector. This approach…

ArticlePublication 2024Extended Cost-Effectiveness Analysis of Interventions to Improve Uptake of Diabetes Services in South Africa
This study examines the potential impact of a conditional cash transfer (CCT) program on diabetes …
This study examines the potential impact of a conditional cash transfer (CCT) program on diabetes diagnosis and treatment service utilization in South Africa (SA) using extended cost-effectiveness analysis (ECEA). Applying a Markov model over a 45-year period, the analysis compares costs, health benefits, and financial risk protection (FRP) attributes of different CCT strategies, drawing from SA-specific data. Three scenarios were simulated: covering diagnosis services only, treatment services only, and both diagnosis and treatment services. Cost-effectiveness,…

ArticlePublication 2008Cost-Effectiveness of Rapid Point-of-Care Prenatal Syphilis Screening in Sub-Saharan Africa
This paper investigates the cost-effectiveness of using rapid point-of-care tests for prenatal syphilis screening among …
This paper investigates the cost-effectiveness of using rapid point-of-care tests for prenatal syphilis screening among pregnant women in sub-Saharan Africa, a region with syphilis prevalence rates as high as 17%, and where traditional multi-test screening methods have been challenging to implement. Focusing on newly available rapid point-of-care screening tests, strategies differed by the initial test [rapid plasma reagin (RPR), immunochromographic strip (ICS)], need for confirmation with Treponema pallidum hemagglutination assay, and number of visits required.…

ArticlePublication 2022Estimated Transmission Outcomes and Costs of SARS-CoV-2 Diagnostic Testing, Screening, and Surveillance Strategies Among a Simulated Population of Primary School Students
In the wake of the COVID-19 pandemic's significant educational disruptions, the U.S. government allocated $10 …
In the wake of the COVID-19 pandemic's significant educational disruptions, the U.S. government allocated $10 billion in March 2021 for testing in schools. The study aimed to analyze the costs and benefits of different COVID-19 testing strategies, particularly focusing on full-time, in-person elementary and middle school education. Utilizing an updated agent-based network model, the study simulated transmission scenarios in schools, considering various testing strategies ranging from diagnostic testing (test-to-stay) to reduce symptom-based isolations, routine screening…

ArticlePublication 2023Effects of Public Financing of Essential Maternal and Child Health Interventions Across Wealth Quintiles in Nigeria: An Extended Cost-Effectiveness Analysis
This study evaluates the potential health and financial risk protection benefits of public financing for …
This study evaluates the potential health and financial risk protection benefits of public financing for maternal, newborn, and child health (MNCH) interventions in Nigeria, focusing on different wealth quintiles. Employing extended cost-effectiveness analysis, the research assesses the impact of a policy ensuring zero out-of-pocket costs for 18 essential MNCH services. Three scenarios were modeled: status quo, uniform scale-up, and pro-poor scale-up. Findings suggest that a 5% increase in coverage for all quintiles could prevent significant…

ArticlePublication 2023Cost-Effectiveness of Novel TB Vaccines: A Modeling Study
A modeling study assessed future costs, cost-savings, and cost-effectiveness of introducing novel tuberculosis (TB) vaccines …
A modeling study assessed future costs, cost-savings, and cost-effectiveness of introducing novel tuberculosis (TB) vaccines in 105 low- and middle-income countries (LMICs) for a range of product characteristics and delivery strategies, compared to a ‘no-new-vaccine’ counterfactual. Vaccine scenarios considered two vaccine product profiles (one targeted at infants, one at adolescents/adults), both assumed to prevent progression to active TB. Vaccine introduction was estimated to require substantial near-term resources, offset by future cost-savings from averted TB burden.…

ArticlePublication 2022Re-Evaluating the Health Impact and Cost-Effectiveness of Tuberculosis Prevention for Modern ART Cohorts
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in …
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in HIV-infected individuals receiving antiretroviral therapy (ART). However, as individuals initiate ART earlier in the course of disease, TB incidence is lower, and it is unclear how ART cost-effectiveness has changed. This study assessed the cost-effectiveness of TPT in contemporary ART cohorts. The authors developed a microsimulation model of TB and HIV and parameterised it using data from a large HIV…

ArticlePublication 2021Impact of COVID-19 on Cancer Diagnosis and Survival in Chile
This paper estimates the impact of the COVID-19 pandemic on delays in cancer diagnosis in …
This paper estimates the impact of the COVID-19 pandemic on delays in cancer diagnosis in Chile, using a microsimulation model of five cancers: breast, cervix, colorectal, prostate, and stomach. The model simulates cancer incidence and progression, as well as stage-specific cancer detection and survival probabilities, and was calibrated to empirical data on monthly detected cases, stage at diagnosis, and 5-year net survival. The analysis accounted for the impact of COVID-19 on month-by-month excess mortality and…
