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 2016Funding Gap for Immunization Across 94 Low- and Middle-Income Countries
This analysis estimates immunization program costs, potentially available financing, and resulting funding gap for 94 …
This analysis estimates immunization program costs, potentially available financing, and resulting funding gap for 94 low- and middle-income countries over the five-year period of 2016–2020. Vaccine financing by country governments, GAVI, and other development sources was forecasted for vaccine, supply chain, and service delivery based on an analysis of comprehensive multi-year plans together with a series of scenarios. The authors found that that delivery of full vaccination programs across the 94 countries would result in a total…

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…

ArticlePublication 2016Health Gains & Financial Protection from Ethiopian Mental Health Strategy: An ECEA
Using the extended cost-effectiveness analysis (ECEA), this paper evaluates the impacts of fully publicly financed …
Using the extended cost-effectiveness analysis (ECEA), this paper evaluates the impacts of fully publicly financed care for depression, bipolar disorder, schizophrenia and epilepsy as part of the mental and neurological package (MN) of the National Mental Health Strategy in Ethiopia. The following outcomes were estimated disaggregated across wealth quintiles: (1) healthy-life-years (HALYs) gained; (2) household out-of-pocket (OOP) expenditures averted (3) expected financial risk protection (FRP); and (4) productivity impact. The MN package is expected to…

ArticlePublication 2016Combining Microsimulation and Agent-Based Modeling
This paper proposes a hybrid model structure combining microsimulation and agent-based modeling to simulate population …
This paper proposes a hybrid model structure combining microsimulation and agent-based modeling to simulate population dynamics. Microsimulation describes the population dynamics at the individual level, and actions conducted by the individuals are generated by stochastic processes. An emerging method is the agent-based model, which focuses on the interactions among individuals and expects to see unexpected situations created from the interactions. In the proposed hybrid model, the microsimulation model takes a role to depict how an…

ArticlePublication 2015Cancer Models and Real-World Data: Better Together
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of …
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of the long-term consequences of care. While models have been influential in informing US cancer screening guidelines under ideal conditions, incorporating detailed data on real-world screening practice has been limited given the complexity of screening processes and behaviors throughout diverse health delivery systems in the United States. The authors describe the synergies that exist between decision-analytic models and health care utilization…

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…

The Commission on Investing in Health published its report, GlobalHealth2035, in 2013, estimating an investment case for a grand convergence in health outcomes globally. In support of the drafting of the Sustainable Development Goals (SDGs), this paper presents estimates of what the grand convergence investment case might achieve—and what investment would be required—by 2030. The authors start with a country-based (bottom-up) analysis of the costs and impact of…!--?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" /-->
