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 2013Estimated Mortality Impact of Vaccinations 2011–2020 in 73 GAVI Alliance Countries
From August to December 2011, a multidisciplinary group with expertise in mathematical modeling was constituted …
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 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 2011Cost-Effectiveness of Psychotherapy for Cluster C Personality Disorders
This article, published in the Journal of Clinical Psychiatry, describes a probabilistic Markov cohort model …
This article, published in the Journal of Clinical Psychiatry, describes a probabilistic Markov cohort model that compares the cost-effectiveness of five treatment modalities (long-term outpatient psychotherapy, short-term and long-term day hospital psychotherapy, and short-term and long-term inpatient psychotherapy) for patients with cluster C personality disorders. The analyses are conducted from the societal and payer perspectives. Patient-level data comes from 466 patients with cluster C personality disorders who were admitted to 6 specialist centers of psychotherapy…

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…

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 2010Model Uncertainty in Economic Evaluation of Health Interventions: Rotavirus Vaccination in Vietnam
Motivated by observed discrepancies between 2 published studies on the cost-effectiveness of rotavirus vaccination in …
Motivated by observed discrepancies between 2 published studies on the cost-effectiveness of rotavirus vaccination in Vietnam, the authors' objectives were to illustrate a specific, systematic approach to assessing model (structure and process) uncertainty and to quantify explicitly the contributions of different sources of variation in the outputs of different studies that share the same research question. On the basis of a series of working definitions of key model elements, the authors developed 5 alternative computer…

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 2010Cost-Effectiveness of Psychotherapy for Cluster B Personality Disorders
This article, published in the British Journal of Psychiatry, presents a probabilistic Markov cohort model …
This article, published in the British Journal of Psychiatry, presents a probabilistic Markov cohort model that compares the cost-effectiveness of three treatment strategies (outpatient, day-hospital and inpatient psychotherapy) for patients with cluster B personality disorders. Patient-level data is used to populate the model and the analyses are conducted from the societal and payer perspectives. From the societal perspective, the findings show that the incremental cost-effectiveness ratio (ICER) of day hospital psychotherapy compared to outpatient psychotherapy…
