ReportPublication 2015Improving Diagnosis in Health Care
Getting the right diagnosis is a key aspect of health care - it provides an …
Getting the right diagnosis is a key aspect of health care - it provides an explanation of a patient's health problem and informs subsequent health care decisions. The diagnostic process is a complex, collaborative activity that involves clinical reasoning and information gathering to determine a patient's health problem. This report, Improving Diagnosis in Health Care, explains that diagnostic errors-inaccurate or delayed diagnoses-persist throughout all settings of care and continue to harm an unacceptable number of patients.…

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 2013Contribution of H. Pylori and Smoking to US Incidence of Gastric Adenocarcinoma: A Microsimulation Model
Although gastric cancer has declined dramatically in the US, the disease remains the second leading …
Although gastric cancer has declined dramatically in the US, the disease remains the second leading cause of cancer mortality worldwide. This analysis estimates the contribution of risk factor trends on past and future intestinal-type non-cardia gastric adenocarcinoma (NCGA) incidence. The authors developed a population-based microsimulation model of intestinal-type NCGA and calibrated it to U.S. epidemiologic data on precancerous lesions and cancer. The model explicitly incorporated the impact of Helicobacter pylori and smoking on disease natural history, for which…

ArticlePublication 2011Model-Based Analyses to Compare Health and Economic Outcomes of Cancer Control: Inclusion of Disparities
In order to identify strategies that improve both population health and ensure its equitable distribution, …
In order to identify strategies that improve both population health and ensure its equitable distribution, the authors developed a typology of cancer disparities that considers types of inequalities among black, white, and Hispanic populations across different cancers. This paper reports on the typology using an existing disease simulation model of cervical cancer that was calibrated to clinical, epidemiological, and cost data in the United States and presents characteristics important for policy discussions. The typology proposed…

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…

The objective of the study was to assess the health and economic outcomes of HPV vaccination in older U.S. women. The authors conducted a cost-effectiveness analysis with an empirically calibrated model using data from published literature; interventions included HPV vaccination added to screening strategies that differ by test (cytology or HPV DNA testing), frequency, and start age versus screening alone.They found that in the context of annual or biennial screening, HPV vaccination of women aged…

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…

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…
