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…

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,…

ReviewPublication 2008Modeling Cervical Cancer Prevention in Developed Countries
Decision-analytic models are increasingly developed to simulate disease burden and interventions in different settings in …
Decision-analytic models are increasingly developed to simulate disease burden and interventions in different settings in order to evaluate the benefits and cost-effectiveness of primary and secondary interventions. This article is a review of mathematical models that have been used to evaluate HPV vaccination in the context of developed countries with existing screening programs. Despite variations in model assumptions and uncertainty in existing data, pre-adolescent vaccination of females in the setting of current screening practices has…

ArticlePublication 2008Mathematical Models of Cervical Cancer Prevention in Latin America and the Caribbean
This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted …
This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (I$/DALY averted) for human papillomavirus (HPV) vaccination of young adolescent girls using population and epidemiologic data for 33 countries in Latin America and the Caribbean (LAC). The authors found that an absolute reduction in lifetime cancer risk varied between countries, depending on incidence, proportion attributable to HPV-16 and 18, and population age-structure; for…

ArticlePublication 2007Decision Analysis: A Personal Account of How It Got Started and Evolved
In this chapter, Howard Raiffa discusses the evolution of decision analysis and his personal involvement …
In this chapter, Howard Raiffa discusses the evolution of decision analysis and his personal involvement in its development. He describes the early days of Operations Research (OR) in the late 1940s with its approach to complex, strategic decision making. After reading John von Neumann and Oskar Morgenstern’s Theory of Games and Economic Behavior (1947) and Abraham Wald’s two books (1947, 1950), he became involved in statistical decision theory. A few years later, after reading Leonard…

ArticlePublication 2007Economic Evaluation of Hepatitis B Vaccination in Low-Income Countries: Cost-Effectiveness Affordability Curves
In the face of uncertainties about both the health and economic consequences of a vaccine …
In the face of uncertainties about both the health and economic consequences of a vaccine program, as well as the availability and magnitude of resources needed to fund the program, cost-effectiveness affordability curves can provide information to decision-makers about the probability that a program will be both cost-effective and affordable: these are distinct but equally relevant considerations in resource-poor settings. This paper describes the application of this method to assess a hepatitis B vaccination program in the…

ArticlePublication 2006Can Discrete Event Simulation be of Use in Modeling Major Depression?
This article, published in Cost Effectiveness and Resource Allocation, reviews the published literature on Markov …
This article, published in Cost Effectiveness and Resource Allocation, reviews the published literature on Markov models in depression and identified potential limitations in using this particular modelling approach in this disease area. Additionally, the authors develop a “Discrete Event Simulation” (DES) model to investigate the benefits and drawbacks of this simulation method compared with Markov modelling techniques. The findings of this study indicate that the most important limitation of using Markov models in depression is…
