ArticlePublication 2017Revealed Willingness-to-Pay vs. Standard Cost-Effectiveness Thresholds
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The …
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The use of CETs based on a country’s income per capita has been criticized for not being grounded in theory or evidence, especially in low and middle-income countries (LMICs). An alternative has been produced for South Africa, based on estimates of life years saved and the country’s committed HIV budget. The authors used a previously -published optimization method to estimate CETs,…

ArticlePublication 2017Using Data-Driven Agent-Based Models to Forecast Emerging Infectious Diseases
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which …
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which was subsequently used in the Ebola forecasting challenge. Producing timely and reliable forecasts for an epidemic of an emerging infectious disease is a challenge. Epidemiologists and policy makers have to deal with poor data quality, limited understanding of the disease dynamics, a rapidly changing social environment and the uncertainty around the effects of various interventions in place. In this setting,…

ArticlePublication 2017Likelihood Approach for Calibration of Stochastic Epidemic Models
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens …
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens given the importance of chance events when the number of infectious individuals is small. However, methods for parameter estimation and prediction for these types of stochastic models remain limited. This paper describes a calibration and prediction framework for stochastic compartmental transmission models of epidemics. The proposed method applies a linear noise approximation to describe the size of the fluctuations, and…

ArticlePublication 2015Broader Economic Impact of Vaccination: Reviewing and Appraising the Strength of Evidence
Economic evaluations of public health programs such as immunization often consider only direct health benefits and …
Economic evaluations of public health programs such as immunization often consider only direct health benefits and medical cost savings. Evidence linking immunization to important benefits in indicators such as childhood development, household behavior, and other macro-economic data are unclear. A conceptual framework of the pathways between immunization and these broader economic benefits was developed through expert consultation. The authors obtained articles from previous reviews, snowballing, and expert consultation, and associated them with one of the pathways and assessed them using modified Grading…

ArticlePublication 2022Modeling the Relative Risk of Incidence and Mortality of Select Vaccine-Preventable Diseases
Immunization is one of the most effective public health interventions, saving millions of lives every …
Immunization is one of the most effective public health interventions, saving millions of lives every year. Ethiopia has seen gradual improvements in immunization coverage and access to child health care services; however, inequalities in child mortality across wealth quintiles and regions remain persistent. This paper models the relative distributional incidence and mortality of four vaccine-preventable diseases (VPDs) (rotavirus diarrhea, human papillomavirus, measles, and pneumonia) by wealth quintile and geographic region in Ethiopia. The authors approach…

ArticlePublication 2021Health Gains and Financial Protection from HPV Vaccination
High out-of-pocket medical expenses for cervical cancer can lead to catastrophic health expenditures and medical …
High out-of-pocket medical expenses for cervical cancer can lead to catastrophic health expenditures and medical impoverishment in many low-resource settings. This article uses a static cohort model that captures the main features of HPV vaccines and population demographics to project health and economic outcomes associated with routine HPV vaccination in Ethiopia. The findings show that, assuming 100% vaccine efficacy against HPV-16/18 and 50% vaccination coverage, routine HPV vaccination could avert up to 970 000 cases…

ArticlePublication 2020Distributional Impact of Supplementary Immunization Activities: Measles
Although evidence shows that inequalities in under-5 mortality in low- and middle-income countries are decreasing, …
Although evidence shows that inequalities in under-5 mortality in low- and middle-income countries are decreasing, disparities persist and highlight the need to prioritize inequality reduction and equity in decision-making at the global and national levels. This article studied the differential coverage impact of routine delivery versus supplementary immunization activities (e.g., campaigns) for the delivery of measles vaccine in defining and comparing an equity impact number across the two distinct vaccine delivery modes. The analysis can…

COVID-19-related policies are fraught with trade-offs. Many of these trade-offs involve dimensions that can be quantitatively weighed using economic evaluation, such as those between health and cost outcomes. Other types of dimensions, such as those involving equity or autonomy, can be harder to quantify but should be considered in a comprehensive health policy decision-making context nonetheless. The authors of this New England Journal of Medicine Perspectives article outline how methods of economic evaluation and decision…

ArticlePublication 2021New Microsimulation Models to Inform Cervical Cancer Control
Health decision models consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis …
Health decision models consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis of cervical cancer, and estimate the long-term impact of preventive interventions. We propose a new health decision modeling framework that de-emphasizes previously used cytologic-colposcopic-histologic diagnoses, which are subjective and lack reproducibility, relying instead on HPV type and duration of infection as the major determinants of model transition probabilities. We posit that new model health states and corollary transitions are universal,…
