There are now a large number of instruments available for assessing health-related quality of life, many of which are used within economic evaluations. When considering the use of quality-of-life instruments, meaningful questions need to be asked to determine whether an instrument has been used...

Markov models are often employed to represent stochastic processes, that is, random processes that evolve over time. In a healthcare context, Markov models are particularly suited to modelling chronic disease. In this article, we describe the use of Markov models for economic evaluation of...

Objective: We constructed a UK-based decision model of palliative care for terminally ill cancer patients who were switched from a weak to a strong opioid so that the expected direct healthcare costs in the UK could be estimated from the time a patient commenced a strong opioid until death....

Clinical trials and meta-analyses of trials are models of clinical reality. A pharmacoeconomic model is a logical, quantitative blend of therapeutic and/or disease management strategies, evidence-based clinical outcomes, patient survival data and/or quality-of-life (utility) data,...

Objective: Conflicting recommendations have been made on whom to treat with antibacterials to eradicate Helicobacter pylori . The present analysis aims to explain the basis of such discrepancies. Design and Setting: The decision in favour of or against antibacterial therapy in patients with...

Objective: The objective of this study was to examine the cost effectiveness of fluvoxamine compared with tricyclic antidepressants (TCAs) in the treatment of patients with depressive episodes. Design and Setting: A Markov process model was constructed to model the effectiveness, as measured by...

While the EuroQOL instrument (EQ-5D) is being considered and used in clinical trials in the United States and Canada, and in large international multicentre studies, population weights for the instrument have never been established in North America. The primary purpose of this investigation was...

Traditionally, US teaching hospitals have subsidised research by charging higher costs for treatment; however, this approach is being challenged. The growth of managed-care organisations, concerned about maximising profits, has led many to argue that clinical research will be damaged, whether by...

The objective of this study was to develop, and subsequently test, a Bayesian discrimination model for the purpose of identifying both the personal and the healthcare system characteristics predictive of hospitalisation for the treatment of patients with diabetes mellitus or commonly observed...
