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 2013Public Finance of Rotavirus Vaccination in India and Ethiopia: Extended CEA
This study uses extended cost-effectiveness analysis (ECEA) to evaluate a hypothetical publicly financed program for …
This study uses extended cost-effectiveness analysis (ECEA) to evaluate a hypothetical publicly financed program for rotavirus vaccination in India and Ethiopia. The authors measured program impact on: (1) averted rotavirus deaths; (2) reduction in household expenditures; (3) financial risk protection; and (4) distributional consequences across the country’s wealth strata. In India and Ethiopia, the program was predicted to decrease rotavirus deaths substantially, and effectively provide financial risk protection among the poor, while also reducing household…

ArticlePublication 2012Modeling the Risks and Benefits of Depression Treatment for Children and Young Adults
This article, published in Value in Health, presents a discrete event simulation model to quantify …
This article, published in Value in Health, presents a discrete event simulation model to quantify the trade-offs with respect to clinical benefits and the risk of fatal and non-fatal suicidal behavior of alternative treatment strategies for a U.S. pediatric population with major depressive disorder. The authors evaluate treatment strategies including: selective serotonin reuptake inhibitors (SSRIs), cognitive behavioral therapy (CBT), and a combination of both. The results show that the use of SSRIs is associated with…

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…

ArticlePublication 2011Health and Economic Impact of HPV 16/18 Vaccination and Cervical Cancer Screening in Eastern Africa
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe …
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe to develop models of HPV-related infection and disease. For each country, they assessed HPV vaccination of girls before age 12 followed by screening with HPV DNA testing once, twice, or three times per lifetime (at ages 35, 40, 45). For women over age 30, they assessed only screening (with HPV DNA testing up to three times per lifetime or VIA…

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…

ArticlePublication 2009Cost Effectiveness Analysis of Including Boys in a HPV Vaccination Program in the U.S.
This article reports on a societal-perspective cost effectiveness analysis of including preadolescent boys in a …
This article reports on a societal-perspective cost effectiveness analysis of including preadolescent boys in a routine human papillomavirus (HPV) vaccination program for preadolescent girls. The analysis included girls and boys aged 12 years; interventions included HPV vaccination of girls alone and of girls and boys in the context of screening for cervical cancer. The authors found that with 75% vaccination coverage and an assumption of complete, lifelong vaccine efficacy, routine HPV vaccination of 12-year-old girls…

ArticlePublication 2009Cost-Effectiveness of Alternative Pregnancy Termination Strategies in Mexico City
This study evaluated the health and economic outcomes associated with three alternative first-trimester abortion techniques …
This study evaluated the health and economic outcomes associated with three alternative first-trimester abortion techniques in Mexico City using a computer-based model to simulate induced abortion and its potential complications. Strategies included alternative modalities for first-trimester pregnancy termination: hospital-based dilatation and curettage (D&C), hospital-based manual vacuum aspiration (MVA), clinic-based MVA and medical abortion using vaginal misoprostol. Outcomes included number of complications, lifetime costs, life expectancy, and quality-adjusted life expectancy. Assuming all options were equally available,…
