Review of economic models assessing the cost-effectiveness of lifestyle interventions for people with impaired g!ucose tolerance and/or impaired fasting glucose

摘要

The aim of this chapter is to assess the existing evidence relating to the long-term cost-effectiveness of lifestyle interventions for the prevention of diabetes in high-risk groups. As part of a previous literature review on screening for diabetes,72 we previously appraised all published studies relevant to this question (up to the end of June 2005) using the British Medical Journal (BMJ) guidelines for reviewers of economic evaluations240 in conjunction with a checklist for good practice in decision-analytic modelling in Health Technology Assessment (HTA).241 The main objective of this chapter is to update the previous review with any relevant studies published up until August 2006. First of all, the findings of the previous review are summarised. Following this, new studies are appraised and then discussed in the context of the previously reviewed papers.
