HTA responses and the classic HTA report.

Abstract

Reports produced in response to the need for health technology assessment (HTA) vary greatly in the methods they use, depending on the decision-maker's needs, the technology's characteristics and the resources available. HTA reports vary from the brief, such as 'vignettes' produced when a new technology emerges, to the exhaustive, such as 'Cochrane reviews' synthesising a mature evidence base. They may address a wide range of different questions. 'Classic HTAs', typically those reports prepared to support NICE appraisal decisions, seek to use scientifically rigorous methods to address a focused policy question. These are based on systematic reviews of the effectiveness evidence but this is often fed into economic models, in order to generate estimates of cost-effectiveness. Future developments in HTA responses will reflect both the embedding of systematic methods and a growing responsiveness to customer needs.
