Bayesian methods in cost-effectiveness studies: objectivity, computation and other relevant aspects.
In a probabilistic sensitivity analysis (PSA) of a cost-effectiveness (CE) study, the unknown parameters are considered as random variables. A crucial question is what probabilistic distribution is suitable for synthesizing the available information (mainly data from clinical trials) about these parameters. In this context, the important role of Bayesian methodology has been recognized, where t...
متن کاملBayesian Variable Selection in Cost-Effectiveness Analysis
Linear regression models are often used to represent the cost and effectiveness of medical treatment. The covariates used may include sociodemographic variables, such as age, gender or race; clinical variables, such as initial health status, years of treatment or the existence of concomitant illnesses; and a binary variable indicating the treatment received. However, most studies estimate only ...
متن کاملCost Effective Use of Formal Methods
Formal methods offer the promise of significant improvements in verification and validation, and may be the only approach capable of demonstrating the absence of undesirable system behavior. But it is widely recognized that these methods are expensive, and their use has been limited largely to high-risk areas such as security and safety. This paper focuses on cost-effective applications of form...
متن کاملMethods for Handling Unobserved Covariates in a Bayesian Update of a Cost-effectiveness Model.
Health economic decision models often involve a wide-ranging and complicated synthesis of evidence from a number of sources, making design and implementation of such models resource-heavy. When new data become available and reassessment of treatment recommendations is warranted, it may be more efficient to perform a Bayesian update of an existing model than to construct a new model. If the exis...
متن کاملBayesian sample size determination for cost-effectiveness studies with censored data
Cost-effectiveness models are commonly utilized to determine the combined clinical and economic impact of one treatment compared to another. However, most methods for sample size determination of cost-effectiveness studies assume fully observed costs and effectiveness outcomes, which presents challenges for survival-based studies in which censoring exists. We propose a Bayesian method for the d...
