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…

From August to December 2011, a multidisciplinary group with expertise in mathematical modeling was constituted by the GAVI Alliance and the Bill & Melinda Gates Foundation to estimate the impact of vaccination in 73 countries supported by the GAVI Alliance. The number of deaths averted in persons projected to be vaccinated during 2011–2020 was estimated for ten antigens: hepatitis B, yellow fever, Haemophilus influenzae type B (Hib), Streptococcus pneumoniae, rotavirus, Neisseria meningitidis serogroup A, Japanese…

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…

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…

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 2010Health and Economic Impact of Rotavirus Vaccination in GAVI-Eligible Countries
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately …
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately borne by children in low-income countries. Motivated by the global recommendation by the WHO that all countries include infant rotavirus vaccination in their national immunization programs, the objective of this analysis was to provide information on the expected health, economic and financial consequences of rotavirus vaccines in the 72 GAVI support-eligible countries. The authors synthesized population-level data from various sources (primarily from…

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…
