Recently, a number of papers have brought up the issue of how to make cost-effectiveness (CE) studies stochastic, i.e. how to obtain confidence intervals for CE ratios. In this note we present a bootstrap procedure for estimating bias-corrected confidence intervals for CE ratios. The bootstrap...

No consensus has yet been reached on how to analyse uncertainty in economic evaluation studies where individual patient data are available for costs and health effects. This paper summarises the available results regarding the analysis of uncertainty on the cost-effectiveness plane and argues...

This study addresses the issue of efficiency in the treatment and rehabilitation of hip fracture patients in Sweden. The treatment and rehabilitation of hip fracture patients is defined in terms of a hip fracture treatment process where resources in orthopaedics and after care are used for...

How to obtain confidence intervals for cost-effectiveness ratios is complicated by the statistical problems to obtain a confidence interval for a ratio of random variables. Different approaches have been suggested in the literature, but no consensus has been reached. In this note we propose an...

A relatively new approach to measure health status is to use non-parametric frontier methods, based on index and production theory. The purpose of this study is to construct and investigate some properties of a non-parametric health status index. The index is based on a non-radial efficiency...

It is shown that the bootstrap method should be applied with care for the Data Envelopment Analysis (DEA) estimator of average technical efficiency if the production frontier is stochastic. A stochastic production frontier leads to an inconsistency of the DEA estimator, which in turn leads to...

Background: Compliance among patients with schizophrenia is typically poor. Consequently, treatments that are equally efficacious under trial-based conditions but face different compliance rates in clinical practice (e.g. due to adverse-effect profile, ease of use, reputation) may have...
