ReportPublication 2015Chapter 4: Cervical Cancer
This chapter focuses on the possibility of primary prevention of cervical cancer as a result …
This chapter focuses on the possibility of primary prevention of cervical cancer as a result of the introduction of two commercially available vaccines against human papillomavirus (HPV). Few low- and middle-income countries (LMICs) have initiated or sustained cytology-based cervical cancer prevention programs, and these countries experience very high incidence and mortality rates. Fortunately, alternative strategies to prevent cervical cancer have been investigated and extensively evaluated in these settings. The authors report findings from cost-effectiveness analyses…

ReviewPublication 2015Medicare's Use of CEA for Prevention (But Not Treatment)
Medicare currently pays for 23 preventive services in its benefits package, the majority of which …
Medicare currently pays for 23 preventive services in its benefits package, the majority of which were added since 2005. In the past decade, the program has transformed from one essentially administering treatment claims, to one increasingly focused on health promotion and maintenance. What is largely unappreciated is the role cost-effectiveness analysis has played in the coverage of preventive services. This study reviews the role of cost-effectiveness analysis in Medicare coverage of preventive services and contrast it…

Tutorial/PrimerPublication, Teaching Resource 2015Calibration of Complex Models through Bayesian Evidence Synthesis: A Tutorial
This tutorial demonstrates how to implement a Bayesian synthesis of diverse sources of evidence to …
This tutorial demonstrates how to implement a Bayesian synthesis of diverse sources of evidence to calibrate the parameters of a complex model. To illustrate these methods, the authors demonstrate how a previously developed Markov model for the progression of human papillomavirus (HPV-16) infection was rebuilt in a Bayesian framework. Transition probabilities between states of disease severity are inferred indirectly from cross-sectional observations of prevalence of HPV-16 and HPV-16–related disease by age, cervical cancer incidence, and…

ArticlePublication 2015Controlling Measles Using Supplemental Immunization: A Mathematical Model
The Measles & Rubella Initiative, a broad consortium of global health agencies, has provided support …
The Measles & Rubella Initiative, a broad consortium of global health agencies, has provided support to measles-burdened countries, focusing on sustaining high coverage of routine immunization of children and supplementing it with a second dose opportunity for measles vaccine through supplemental immunization activities (SIAs). Authors estimate optimal scheduling of SIAs in countries with the highest measles burden using an age-stratified dynamic compartmental model of measles transmission. They explore the frequency of SIAs in order to achieve…

ArticlePublication 2014Rise and Fall of HIV in High-Prevalence Countries: A Challenge for Mathematical Modeling
Several countries with generalized, high-prevalence HIV epidemics, mostly in sub-Saharan Africa, have experienced rapid declines …
Several countries with generalized, high-prevalence HIV epidemics, mostly in sub-Saharan Africa, have experienced rapid declines in transmission. These HIV epidemics, often with rapid onsets, have generally been attributed to a combination of factors related to high-risk sexual behavior. The subsequent declines in these countries began prior to widespread therapy or implementation of any other major biomedical prevention. This change has been construed as evidence of behavior change, often on the basis of mathematical models, but…

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…

The purpose of this review is to provide guidance for determining when incorporating a decision-analytic model alongside a systemic review would be of added value for decision making purposes. The purpose of systematic reviews is to synthesize the current scientific literature on a particular topic in the form of evidence reports and technology assessments to assist public and private organizations in developing strategies that improve the quality of health care and decision making. However, there…

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 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…

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…
