ArticlePublication 2014HIV Cure Strategies: How Good Must They be to Improve on ART?
This article uses a microsimulation model to explore under what circumstances three HIV cure strategies …
This article uses a microsimulation model to explore under what circumstances three HIV cure strategies (gene therapy, chemotherapy and stem cell transplantation (SCT)) would improve efficacy, toxicity, cost and quality of life outcomes compared to current antiretroviral therapy (ART). Assuming a cost-effectiveness threshold of $100,000 per QALY, results show that gene therapy was cost-effective compared to ART with an efficacy of 10%, relapse rate of 0.5%/month, and cost of $54,000. Chemotherapy was cost-effective with an…

ArticlePublication 2014Cost-Effectiveness of Second-Generation Antipsychotics for the Treatment of Schizophrenia
This article, published in Value in Health, describes a Markov model that compares the cost-effectiveness …
This article, published in Value in Health, describes a Markov model that compares the cost-effectiveness of alternate sequences of treatment strategies using second-generation antipsychotics (SGAs) for patients with schizophrenia. First-line treatments include one of the four SGAs: olanzapine (OLZ), risperidone (RSP), quetiapine (QTP), and ziprasidone (ZSD). Patients are able switch to another of these antipsychotics as second-line therapy, and only clozapine (CLZ) is allowed as third-line treatment. Model input parameters were obtained from the Clinical…

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 2010Empirically Evaluating Decision-Analytic Models
To augment model credibility, evaluation via comparison to independent, empirical studies is recommended. The authors …
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 2007Modeling HPV and Cervical Cancer in the U.S. for Analyses of Screening and Vaccination
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty …
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty about the natural history of disease that was used to provide quantitative insight into U.S. policy choices for cervical cancer prevention. The authors developed a stochastic microsimulation of cervical cancer that distinguishes different HPV types by their incidence, clearance, persistence, and progression. For each set of sampled input parameters, likelihood-based goodness-of-fit (GOF) scores were computed based on comparisons between model-predicted…

ArticlePublication 2002Empirically Calibrated Model of Hepatitis C Virus Infection in the United States
This article presents an epidemiologic model of hepatitis C in the United States. The authors …
This article presents an epidemiologic model of hepatitis C in the United States. The authors used empirical calibration of model parameters to gain insights into uncertainty in the natural history of hepatitis C and to improve future projections. The authors identified model inputs by way of a systematic review. Model simulations were conducted and model predictions were compared with epidemiologic data on infection prevalence and mortality from liver cancer. Goodness-of-fit criteria were used to identify…

ArticlePublication 2000Preference-Based Measures in Economic Evaluation in Health Care
Estimating preferences for states of health has been an active area of research in recent …
Estimating preferences for states of health has been an active area of research in recent years. Unlike psychophysical approaches, which discriminate levels of health status, preference-based approaches incorporate values or utilities for health outcomes and can be used in cost-effectiveness analyses to aid resource allocation decisions. This chapter considers issues and controversies involved in using preference-based measures in economic evaluation in health care, with a particular emphasis on cost-utility analysis and the estimation of quality-adjusted…
