ArticlePublication 2013Contribution of H. Pylori and Smoking to US Incidence of Gastric Adenocarcinoma: A Microsimulation Model
Although gastric cancer has declined dramatically in the US, the disease remains the second leading …
Although gastric cancer has declined dramatically in the US, the disease remains the second leading cause of cancer mortality worldwide. This analysis estimates the contribution of risk factor trends on past and future intestinal-type non-cardia gastric adenocarcinoma (NCGA) incidence. The authors developed a population-based microsimulation model of intestinal-type NCGA and calibrated it to U.S. epidemiologic data on precancerous lesions and cancer. The model explicitly incorporated the impact of Helicobacter pylori and smoking on disease natural history, for which…

ArticlePublication 2013Health Benefits and Cost-Effectiveness of Strategies to Reduce Maternal Mortality in Afghanistan
This article, published in Health Policy and Planning, disaggregates data on pregnancies in Afghanistan to …
This article, published in Health Policy and Planning, disaggregates data on pregnancies in Afghanistan to evaluate health outcomes and cost-effectiveness of interventions related to childbirth. These interventions include antenatal care, family planning, skilled birth attendance, access to transport, referral facilities, and quality of overall care. Outcomes include pregnancy-related complications, maternal deaths, maternal mortality ratios, costs and cost-effectiveness ratios. The authors report that increasing family planning would be the most effective individual intervention. The model suggests…

ArticlePublication 2012Health and Economic Outcomes of Interventions to Reduce Pregnancy-Related Mortality in Nigeria
This paper examines the cost-effectiveness and impact of individual and integrated packages of interventions aimed …
This paper examines the cost-effectiveness and impact of individual and integrated packages of interventions aimed to reduce maternal mortality in Nigeria, a country with extremely high maternal mortality rates. Using a previously validated model adapted to the Nigerian context, the study finds that an increase of access to family planning is the most effective individual strategy, which not only reduces pregnancy-related mortality but also proves to be economically efficient. However, relying solely on family planning…

GuidelinesPublication 2011HPV Vaccine Introduction in LMIC's: Guidance on the Use of Cost-Effectiveness Models
This article is a literature review of HPV vaccination models suitable for low-income and middle-income …
This article is a literature review of HPV vaccination models suitable for low-income and middle-income country use to provide information about the feasibility of using such models in a developing country setting. The authors evaluated models in terms of their capacity, requirements, limitations and comparability. Their literature review identified six HPV vaccination models suitable for low-income and middle-income country use and representative of the literature in terms of provenance and model structure. Each model was…

ArticlePublication 2010Cost-Effectiveness of Alternative Pregnancy Termination Strategies in Nigeria and Ghana
To explore the policy implications of increasing access to safe abortion in Nigeria and Ghana, …
To explore the policy implications of increasing access to safe abortion in Nigeria and Ghana, the authors developed a computer-based decision analytic model which simulates induced abortion and its potential complications in a cohort of women. The model was used to compare the costs and benefits of unsafe abortion and three first-trimester abortion modalities: hospital-based dilatation and curettage, hospital- and clinic-based manual vacuum aspiration (MVA), and medical abortion using misoprostol (MA). The results showed that…

ArticlePublication 2010Empirically Evaluating Decision-Analytic Models
To augment model credibility, evaluation via comparison to independent, empirical studies is recommended. The authors …
To augment model credibility, evaluation via comparison to independent, empirical studies is recommended. The authors developed a structured reporting format for model evaluation and conducted a structured literature review to characterize current model evaluation recommendations and practices. As an illustration, they applied the reporting format to evaluate a microsimulation of human papillomavirus and cervical cancer. The model's outputs and uncertainty ranges were compared with multiple outcomes from a study of long-term progression from high-grade precancer…

ReviewPublication 2010Validation of Population-Based Disease Simulation Models: A Review
This article develops a framework for validating population-based chronic disease simulation models, and reviews the …
This article develops a framework for validating population-based chronic disease simulation models, and reviews the principles and methods for such models. While computer simulation models are used increasingly to support public health research and policy, questions about their quality persist. Based on the review, the authors formulated a set of recommendations for gathering evidence of model credibility. They find that evidence of model credibility derives from examining: 1) the process of model development, 2) the…

ArticlePublication 2009Cost-Effectiveness of HPV Vaccination and Cervical Cancer Screening in Women Aged 30+ Years in the U.S.
The objective of the study was to assess the health and economic outcomes of HPV …
The objective of the study was to assess the health and economic outcomes of HPV vaccination in older U.S. women. The authors conducted a cost-effectiveness analysis with an empirically calibrated model using data from published literature; interventions included HPV vaccination added to screening strategies that differ by test (cytology or HPV DNA testing), frequency, and start age versus screening alone.They found that in the context of annual or biennial screening, HPV vaccination of women aged…

ArticlePublication 2007Including Boys in an HPV Vaccination Program: A CEA in a Low-Resource Setting
This paper looks at the cost-effectiveness of including boys vs girls alone in a pre-adolescent vaccination …
This paper looks at the cost-effectiveness of including boys vs girls alone in a pre-adolescent vaccination program against human papillomavirus (HPV) types 16 and 18 in Brazil. Using demographic, epidemiological, and cancer data from Brazil, the authors developed a dynamic transmission model of HPV infection between males and females. Model-projected reductions in HPV incidence under different vaccination scenarios were applied to a stochastic model of cervical carcinogenesis to project lifetime costs and benefits. They found that at 90%…
