ArticlePublication 2013Validation and Calibration of a Simulation Model of Pediatric HIV Infection
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of …
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model framework. This CEPAC-Pediatric model was then validated by varying CD4 data and comparing the corresponding model-generated survival curves to empirical survival curves obtained from the International Epidemiologic Database to Evaluate AIDS (IeDEA). The model was calibrated to other African countries by systematically varying immunologic and HIV mortality-related input parameters. In the calibration analyses, the model-generated…

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 2012Value of Family Planning for Improving Maternal Health in Rural Afghanistan
This article, published in the Afghanistan Journal of Public Health, uses a model designed to …
This article, published in the Afghanistan Journal of Public Health, uses a model designed to simulate the natural history of pregnancy and associated maternal mortality and morbidity contextualized to Afghanistan to assess the cost-effectiveness of family planning in the rural Maywand district of Kandahar. Using total fertility rate, pregnancy-related complications, maternal mortality ratio, lifetime risk of maternal death, and proportionate mortality ratio as outcomes, the model finds that increasing family planning from 8% to 30-50% could…

ArticlePublication 2010Clinical Benefits, Costs, and Cost-Effectiveness of Neonatal Intensive Care in Mexico
This article reports on a study to estimate the clinical outcomes, costs, and cost-effectiveness of …
This article reports on a study to estimate the clinical outcomes, costs, and cost-effectiveness of neonatal intensive care in Mexico. The authors conducted a cost-effectiveness analysis using a decision analytic model of health and economic outcomes following preterm birth. Model parameters governing health outcomes were estimated from Mexican vital registration and hospital discharge databases, supplemented with meta-analyses and systematic reviews from the published literature. Costs were estimated on the basis of data provided by the…

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…
